The protocol of this study has been approved by the Human Research Ethics Committee of Longhua Hospital Affiliated with Shanghai University of Traditional Chinese Medicine (Approval Number: 2023-LHXS-030). Before the trial, written informed consent was provided by each patient included in the study. A total of 76 patients with stage I-II frozen shoulder in the rehabilitation department of Longhua Hospital affiliated to Shanghai University of Traditional Chinese Medicine from December 2022 to May 2023, who met the inclusion criteria, were randomly divided into a control group and a treatment group, with 38 cases in each group. The operator must be familiar with the anatomy of the shoulder joint and the specific surgical method.
1. Recruitment of patients
<ol>
	<li>Use the following inclusion criteria to enroll patients in this study: Conform to the diagnostic criteria of frozen shoulder; stage I or II frozen shoulder; regardless of gender, 40-65 years old; VAS score &#8804; 7; without other treatment at the same time.</li>
	<li>Use the following exclusion criteria to not include patients in this study: Patients with blood coagulation dysfunction; diabetic patients with unstable blood sugar control; pregnant pand lactating women; patients with damaged treatment sites or serious infection; Patients with allergies to anesthesia.</li>
</ol>
2. Exercises regime for control group
<ol>
	<li>Subject patients in the control group to a treatment course of functional exercises as described below19.
	<ol>
		<li>Hand wall climbing: Ask the patient to stand facing the wall with both feet open and raising both hands to climb up along the wall. Ask the patient to take the hands to the highest scales with the maximum tolerance and record this for each patient.</li>
		<li>Assisted hand: In a standing position, ask the patient to keep the affected upper limb in the state of backward extension and perform internal rotation to the opposite side by pulling the wrist of the affected upper limb with the healthy upper limb, and then maintain the upward pulling state to the maximum tolerance for the patient.</li>
		<li>Pendulum swings: In standing and bending down position, ask the patient to support the healthy arm of each patient and drop to the affected side and perform the back and forth, left and right, as well as circle movements. Increase the range of motion when the symptoms are improved and draw circles by holding an object which is 1-2 kg (such as water bottles, dumbbells) to increase the intensity of stretching exercises.</li>
	</ol>
	</li>
	<li>Course of functional exercise: Ensure the patients in the control group perform functional exercises every day including wall climbing, assisted hand and the pendulum swings, 30 times/day for 4 weeks. 
	NOTE: The functional exercise must be carried out within the tolerance range; otherwise, it may cause soft tissue strain in the shoulder and lead to deterioration of the condition.</li>
	<li>Follow the principle of - from light to heavy, from small to large, step by step and continuously - during the functional exercise. Ask the patient to avoid long-term shoulder work, heavy lifting, or strenuous activities, though the patient can perform all day-to-day activities during treatment.</li>
</ol>
3. Exercise regime for treatment group
<ol>
	<li>Subject patients in the treatment group to small needle knife therapy with functional exercises.</li>
	<li>Preoperative preparation
	<ol>
		<li>Material preparation (Figure 1): Sterilize disposable medical plastic cup, medical tweezers, absorbent cotton ball, dressing block, a 40 mm x 40 mm disposable sterile small needle knife, marker pen, type II skin disinfectant, 2% lidocaine hydrochloride, sterile water for injection, 10 mL disposable sterile syringe, disposable sterile injection needle, rubber surgical gloves, self-adhesive dressing.</li>
		<li>Patient information check: Check the basic information of each patient (name, age, affected shoulder). Explain the process and advantages of the small needle knife therapy. Make sure that the patients fully understand and relax during the operational procedure.</li>
		<li>Patient preparation: Fully expose the affected shoulder in a sitting position.</li>
		<li>Positioning (Figure 2): Mark the obvious tenderness points of the affected shoulder, such as the coracoid process point (attachment point of the short head of the biceps), lesser tuberosity of greater (attachment point of the subscapular muscle), intertubercular sulcus (attachment point of the long head of the biceps muscle), subacromial bursae (attachment point of the supraspinatus muscle), 2 cm behind the greater tuberosity of humerus (attachment point of the teres minor muscle)20.</li>
		<li>Disinfection: Prepare cotton balls in type II skin disinfectant. Routinely disinfect the skin 3x with gradually reduced diameter starting from 15 cm around the marking point.</li>
	</ol>
	</li>
	<li>Operational procedure (Figure 2)
	<ol>
		<li>Load 5 mL 2% lidocaine plus 5 mL of sterile water into&#160;a 10 mL syringe to prepare a 10 mL 1% lidocaine working solution.&#160;</li>
		<li>Replace the 22G needle with a 25G needle (use thinner needles to ease the pain). Wear the sterile gloves on the left hand and hold the syringe in the right hand.</li>
		<li>Insert the needle into the mark and make sure no blood returns upon aspiration. Perpendicularly inject 1-2 mL of 1% lidocaine working solution at each marked point.</li>
		<li>Small needle knife insertion (Figure 2): Wear sterile gloves in the right hand to hold the small needle knife. Rapidly insert the small needle knife into the lidocaine injection site perpendicularly with a depth of about 1-3 cm. Make sure that the blade of the small needle knife is parallel to the muscle fibers to avoid damage to important blood vessels and nerves.</li>
		<li>Perform the 3-step manipulation of longitudinal incision, stripping and releasing the adhesion7,15. The patient will feel local soreness and pain, and the operator will feel resistance under the knife.</li>
		<li>Withdraw the needle when the operator feels a sense of looseness under the knife.</li>
	</ol>
	</li>
	<li>Postoperative care (Figure 2)
	<ol>
		<li>Press the injection site for 1 min with a dry sterile cotton ball. Cover the operating area with a sterile self-adhesive dressing.</li>
		<li>Assist the patients to dress well. 
		NOTE: Put the medical waste into the medical waste trash can.</li>
		<li>Ask the patient to sit still for about 15 min before leaving the operating room to avoid postoperative discomfort. Advice the patient to keep the self-adhesive dressing dry until it is removed 48 h later to avoid bleeding and infection.</li>
	</ol>
	</li>
	<li>Course of small needle knife therapy21: Subject the patients in the treatment group to small needle knife therapy, once a week with a total of 4 sessions. Carry out the same functional exercises for patients in the treatment group as done for the control group.</li>
</ol>
4. Post-intervention outcome assessments
<ol>
	<li>Evaluation index22,23,24
	<ol>
		<li>Use the visual analogue scores (VAS), the Constant and Murley scores (CMS), and the thickness of CHL under ultrasound to assess the outcome. 
		NOTE: The baseline measurements were performed before and one week after the treatment.</li>
	</ol>
	</li>
	<li>Assessment instruments
	<ol>
		<li>Use the GJJDC01 high-precision joint motion electronic measuring instrument for shoulder joint motion measurement and a portable color ultrasound system (Figure 3).</li>
	</ol>
	</li>
	<li>Assessment instruments operation method (Figure 3)
	<ol>
		<li>Measurement of shoulder range of motion.
		<ol>
			<li>Press ON to turn on the power. Ask the subject to uplift the shoulder to the maximum angle possible. Rotate the measuring ruler and obtain the measured value.</li>
			<li>Set the measuring instrument scale back to 0 and repeat the measurement 2x. Press and hold OFF to turn the power off.</li>
		</ol>
		</li>
		<li>Measurement of the thickness of CHL using an ultrasound.
		<ol>
			<li>Turn ON the ultrasound machine by pressing the Power button. Press the Patient button, click New Patient, and enter the name of the subject.</li>
			<li>Ask the patient to fully expose the affected shoulder in a seated position. Move the shoulder joint of the patient passively to locate the CHL. Align the ultrasound probe with the CHL.</li>
			<li>Press the Freeze button to save the ultrasound image. Press the Caliper button to test CHL thickness. Record the measurement and turn it OFF.</li>
		</ol>

In this study, we found that the small needle knife therapy significantly relieved the pain symptoms, improved the shoulder joint function, reduced the thickness of CHL, and improved the quality of life in stage I-II frozen shoulder patients. The small needle knife therapy had exact effect on frozen shoulder. However, the operation site is controversial. Due to the different knowledge backgrounds, many operation sites can be selected to treat frozen shoulders with small needle knife. The main operation sites are tender p...

Frozen shoulder is a disease characterized by pain and limitation of active and passive shoulder movement, which causes great inconvenience to the work and life of patients1. The global incidence of frozen shoulder is 2%-5%2,3 and higher in females than in males, showing a certain genetic tendency4. The majority of frozen shoulder patients are 40-60 years old5. Moreover, the frozen shoulder brings about a heavy social burden due to the longer recovery cycle and the absence of established treatment consensus in the clinic practice.
The main treatment methods for frozen shoulders include oral or external use of herbal medicine, acupuncture, massage, functional exercise, and so on6; however, the compliance of the patients is poor due to the multiple treatment frequency and longer time-consuming, and cannot meet the urgent necessities of patients to improve pain and functional limitations. Therefore, it is urgently needed to identify more effective therapeutics in the clinical management of frozen shoulder patients.
Small needle knife therapy is a special and effective external treatment of traditional Chinese medicine, which has arisen rapidly in the field of traditional Chinese medicine in recent decades7. It has the advantages of quick effect, definite curative effect, and high repeatability. Moreover, the operation instrument is cheap and easy to obtain, the operation process is simple, and the method is not limited by the environment and condition. The normal work and life of patients are not affected after the small needle knife therapy since the micro-incision will be recovered quickly without damage to the body, causing infection, or other side effects8,9,10,11. Systematic reviews showed that the efficacy of small needle knife on frozen shoulder was significantly superior to acupuncture, massage, and oral Chinese medicine12,13. Modern studies show that the mechanism of small needle knife treatment of frozen shoulder is to dredge the meridians and collaterals, promote the circulation of qi and blood, cut and strip the lesion tissue, remove adhesion, promote tissue repair, and restore the dynamic balance of the human body14,15.
The protocol presented here demonstrates the operation of small needle knife in treating frozen shoulders including patient management, material preparation, positioning, operation, and postoperative care. The purpose of this protocol is to relieve the pain and functional limitations and improve the living ability of patients with frozen shoulders.
With the development of small needle knife therapy, its application has been extended from the treatment of neck, shoulder, waist, leg pain, and other muscle and bone diseases to internal medicine, surgery, gynecology, pediatrics, and other diseases, playing an increasingly important role in the field of rehabilitation medicine16. In recent years, the small needle knife shows a more accurate, scientific, and safe therapeutic efficacy due to the application of ultrasound-guided small needle knife visualization therapy, whose development has entered a new stage17,18.

clinical efficacy of small needle knife therapy on stage i-ii frozen shoulder

Frozen shoulder is a kind of aseptic inflammatory disease of the shoulder caused by strain, trauma, and other reasons, resulting in shoulder joint pain and limited function. The protocol presented here demonstrates the operation of a small needle knife in treating frozen shoulders, including patient management, material preparation, positioning, operation, and postoperative care. The purpose of this protocol is to relieve the pain and functional limitations and improve the living ability of patients with frozen shoulders. In our study, 76 stage I-II frozen shoulder patients who met the inclusion criteria were randomly divided into a control group and a treatment group (n=38). Patients in the control group received functional exercise, while the treatment group received small needle knife therapy with functional exercise. The visual analogue scores (VAS), the Constant and Murley scores (CMS), and the thickness of the coracohumeral ligament (CHL) under ultrasound were evaluated. After small needle knife therapy, the VAS score was significantly lower in the treatment group (5.11 &plusmn; 0.89) than in the control group (5.49 &plusmn; 0.65; t=-2.065, p&lt;0.05); the CMS score was significantly higher in the treatment group (64.72 &plusmn; 4.78) than in the control group (60.97 &plusmn; 6.00; t=2.947, p&lt;0.05); the CHL thickness was significantly decreased in the treatment group (2.38 &plusmn; 0.36) than in the control group (2.57 &plusmn; 0.42; t=-2.117, p&lt;0.05). These results indicate that the small needle knife significantly relieved the pain symptoms, improved the shoulder function, reduced the CHL thickness, and improved the quality of life and, therefore, had significant therapeutic efficacy in stage I-II frozen shoulder patients.

In the control group, 1 patient received other treatment (intra-articular steroid injection) due to aggravation of pain, so the trial was terminated, and the remaining 37 patients in the control group were included in the final statistical analysis. For 2 patients in the treatment group CHL could not be detected under ultrasound, so the test was eliminated, and the remaining 36 patients in the treatment group entered the final statistical analysis.

Reverse Total Shoulder Arthroplasty

Reverse total shoulder arthroplasty was initially approved for use in rotator cuff arthropathy and well as chronic pseudoparalysis without arthritis in patients who were not appropriate for tendon transfer reconstructions. Traditional surgical options for these patients were limited and functional results were sub-optimal and at times catastrophic. The use of reverse shoulder arthroplasty has been found to effectively restore these patients function and relieve symptoms associated with their disease. The procedure can be done through two approaches, the deltopectoral or the superolateral. Complication rates associated with the use of the prosthesis have ranged from 8-60% with more recent reports trending lower as experienced is gained. Salvage options for a failed reverse shoulder prosthesis are limited and often have significant associated disability. Indications for the use of this prosthesis continue to be evaluated including its use for revision arthroplasty, proximal humeral fracture and tumor. Careful patient selection is essential because of the significant risks associated with the procedure.

Reverse total shoulder arthroplasty is indicated for the treatment of conditions that cannot be treated with conventional arthroplasty or other procedures. These primarily include degenerative and incapacitating conditions with irreparable rotator cuff and loss of the normal biomechanical coupling of the shoulder.

Cytotoxic Efficacy of Photodynamic Therapy in Osteosarcoma Cells In Vitro

In recent years, there has been the difficulty in finding more effective therapies against cancer with less systemic side effects. Therefore Photodynamic Therapy is a novel approach for a more tumor selective treatment.
Photodynamic Therapy (PDT) that makes use of a nontoxic photosensitizer (PS), which, upon activation with light of a specific wavelength in the presence of oxygen, generates oxygen radicals that elicit a cytotoxic response1. Despite its approval almost twenty years ago by the FDA, PDT is nowadays only used to treat a limited number of cancer types (skin, bladder) and nononcological diseases (psoriasis, actinic keratosis)2.
The major advantage of the use of PDT is the ability to perform a local treatment, which prevents systemic side effects. Moreover, it allows the treatment of tumors at delicate sites (e.g. around nerves or blood vessels). Here, an intraoperative application of PDT is considered in osteosarcoma (OS), a tumor of the bone, to target primary tumor satellites left behind in tumor surrounding tissue after surgical tumor resection. The treatment aims at decreasing the number of recurrences and at reducing the risk for (postoperative) metastasis.
In the present study, we present in vitro PDT procedures to establish the optimal PDT settings for effective treatment of widely used OS cell lines that are used to reproduce the human disease in well established intratibial OS mouse models. The uptake of the PS mTHPC was examined with a spectrophotometer and phototoxicity was provoked with laser light excitation of mTHPC at 652 nm to induce cell death assessed with a WST-1 assay and by the counting of surviving cells. The established techniques enable us to define the optimal PDT settings for future studies in animal models. They are an easy and quick tool for the evaluation of the efficacy of PDT in vitro before an application in vivo.

Preparation and Respirometric Assessment of Mitochondria Isolated from Skeletal Muscle Tissue Obtained by Percutaneous Needle Biopsy

Respirometric profiling of isolated mitochondria is commonly used to investigate electron transport chain function. We describe a method for obtaining samples of human Vastus lateralis, isolating mitochondria from minimal amounts of skeletal muscle tissue, and plate based respirometric profiling using an extracellular flux (XF) analyzer. Comparison of respirometric profiles obtained using 1.0, 2.5 and 5.0 &#956;g of mitochondria indicate that 1.0 &#956;g is sufficient to measure respiration and that 5.0 &#956;g provides most consistent results based on comparison of standard errors. Western blot analysis of isolated mitochondria for mitochondrial marker COX IV and non-mitochondrial tissue marker GAPDH indicate that there is limited non-mitochondrial contamination using this protocol. The ability to study mitochondrial respirometry in as little as 20 mg of muscle tissue allows users to utilize individual biopsies for multiple study endpoints in clinical research projects.

Methods for biopsy of Vastus lateralis, preparation of purified mitochondria, and respirometric profiling are described. The use of small muscle volume makes this technique suitable for clinical research applications.

A Clinical Trial Assessing the Safety, Efficacy, and Delivery of Olive-Oil-Based Three-Chamber Bags for Parenteral Nutrition

Limited evidence exists to precisely estimate efficacy and safety differences between parenteral nutrition (PN) prepared using olive-oil-based three-chamber bags (3CBs) and soybean-oil-based compounded bags (CoBs) in hospitalized adult patients. We designed a multicenter, randomized, prospective, open-label, noninferiority protocol to compare the efficacy, safety, and distribution of olive-oil-based 3CBs and soybean-oil-based CoB formulations in adult Chinese patients requiring PN during surgical intervention. Subjects were randomized to receive either one of the study treatments using an interactive voice or web-based recognition system in accordance with the randomization code. Randomization was further stratified based on the study site and surgical category. Both treatment groups received similar amounts of calories and protein. In addition, the two study treatments contained a similar composition of the amino-acid component. The only difference between the two PN formulations was the lipid constitution. The duration of administration of study treatments was a minimum of 5 days up to a maximum of 14 days after the surgical procedure. The primary efficacy endpoint was serum prealbumin levels on day 5 of the study. Noninferiority was proved if the anti-log of the lower bound of the 95% confidence interval (CI) of the treatment difference was at least 0.80. Other efficacy measures included treatment preparation time; duration to achieve tolerability of oral nutrition; associated infectious complications; length of hospitalization; and laboratory assessment of markers of nutrition, inflammation, metabolism, and oxidative stress. A total of 458 patients were enrolled in the study. The results showed that olive-oil-based 3CBs were non-inferior to soybean-based CoBs, besides being well tolerated. The infection rate was found to be significantly lower in the olive-oil-based 3CB group. Thus, this study may be used as a reference for future research on lipid emulsion and 3CBs.

Here, we present a protocol for a study comparing the efficacy, safety, and delivery of olive-oil-based 3CB and soybean-oil-based CoB formulations in adults requiring parenteral nutrition. The results revealed that olive-oil-based 3CBs is non-inferior and well tolerated compared to soybean formulations.

Proton Therapy Delivery and Its Clinical Application in Select Solid Tumor Malignancies

Radiation therapy is a frequently used modality for the treatment of solid cancers. Although the mechanisms of cell kill are similar for all forms of radiation, the in vivo properties of photon and proton beams differ greatly and maybe exploited to optimize clinical outcomes. In particular, proton particles lose energy in a predictable manner as they pass through the body. This property is used clinically to control the depth at which the proton beam is terminated, and to limit radiation dose beyond the target region. This strategy can allow for substantial reductions in radiation dose to normal tissues located just beyond a tumor target. However, the degradation of proton energy in the body remains highly sensitive to tissue density. As a consequence, any changes in tissue density during the course of treatment may significantly alter proton dosimetry. Such changes may occur through alterations in body weight, respiration, or bowel filling/gas, and may result in unfavorable dose deposition. In this manuscript, we provide a detailed method for the delivery of proton therapy using both passive scatter and pencil beam scanning techniques for prostate cancer. Although the described procedure directly pertains to prostate cancer patients, the method may be adapted and applied for the treatment of virtually all solid tumors. Our aim is to equip readers with a better understanding of proton therapy delivery and outcomes in order to facilitate the appropriate integration of this modality during cancer therapy.

The fundamentals of radiation planning and delivery for proton therapy using prostate cancer as a model are presented. The application of these principles to other selected disease sites highlights how proton radiotherapy may enhance clinical outcomes for cancer patients.

A Pre-clinical Rat Model for the Study of Ischemia-reperfusion Injury in Reconstructive Microsurgery

Ischemia-reperfusion injury is the main cause of flap failure in reconstructive microsurgery. The rat is the preferred preclinical animal model in many areas of biomedical research due to its cost-effectiveness and its translation to humans. This protocol describes a method to create a preclinical free skin flap model in rats with ischemia-reperfusion injury. The described 3 cm x 6 cm rat free skin flap model is easily obtained after the placement of several vascular ligatures and the section of the vascular pedicle. Then, 8 h after the ischemic insult and completion of the microsurgical anastomosis, the free skin flap develops the tissue damage. These ischemia-reperfusion injury-related damages can be studied in this model, making it a suitable model for evaluating therapeutic agents to address this pathophysiological process. Furthermore, two main monitoring techniques are described in the protocol for the assessment of this animal model: transit-time ultrasound technology and laser speckle contrast analysis.

Here, we describe a pre-clinical animal model for studying the pathophysiology of ischemia-reperfusion injury in reconstructive microsurgery. This free skin flap model based on the superficial caudal epigastric vessels in the rat may also allow for the evaluation of different therapies and compounds to counteract ischemia-reperfusion injury-related damage.

Large Animal Model for Evaluating the Efficacy of the Gene Therapy in Ischemic Heart

Coronary artery disease is one of the significant causes of mortality and morbidity worldwide. Despite the progression of current therapeutics, a considerable proportion of coronary artery disease patients remain symptomatic. Gene therapy-mediated therapeutic angiogenesis offers a novel therapeutic method for improving myocardial perfusion and relieving symptoms. Gene therapy with different angiogenic factors has been studied in few clinical trials. Due to the novelty of the method, the progress of myocardial gene therapy is a continuous path from bench to bedside. Therefore, large animal models are needed for evaluating the safety and efficacy. The more the large animal model identifies the original disease and the endpoints used in clinics, the more predictable outcomes are from clinical trials. Here, we introduce a large animal model for evaluating the efficacy of the gene therapy in the ischemic porcine heart. We use clinically relevant imaging methods such as ultrasound imaging and 15H2O-PET. For targeting the gene transfers into the desired area, electroanatomical mapping is used. The aim of this method is: (1) to mimic chronic coronary artery disease, (2) to induce therapeutic angiogenesis at hypoxic areas of the heart, and (3) to evaluate the safety and efficacy of the gene therapy by using relevant endpoints.

Myocardial gene therapy for ischemic heart disease holds great promise for future therapeutics. Here, we introduce a large animal model for evaluating the efficacy of gene therapy in the ischemic heart.

FSN Therapy for Knee Osteoarthritis Pain Management

Fu's Subcutaneous Needling for Knee Osteoarthritis Pain

Fu's subcutaneous needling (FSN) is a new acupuncture and dry needling technique based on traditional Chinese medicine. It rapidly produces long-lasting effects in soft tissue injuries, particularly in painful musculoskeletal conditions, by providing stimulation primarily in the subcutaneous area. Osteoarthritis (OA) is the most common joint disease in adults worldwide and is often accompanied by a painful syndrome of structural changes in the peripheral joints of the knee. However, the etiology of OA pain is not fully understood, though myofascial trigger points (MTrPs) are commonly found in the lower limb muscles (so-called "tightened muscles") of patients with knee OA. 
FSN has been used in many fields for the treatment of acute pain problems and can relieve muscle contraction from MTrPs, thereby improving the local circulation. This study recruited patients with pain from knee OA into an FSN group or a transcutaneous electrical nerve stimulation (TENS) group with three treatment sessions and a follow-up over the course of 2 weeks. The results showed that FSN was effective in treating soft tissue pain around the knee with OA. This study aimed to establish and visualize three key technical indicators during FSN therapy, including the FSN needle insertion point and layer; the frequency and duration of the swaying movement; and the manipulation of the reperfusion approach. These findings have great potential for future applications in myofascial pain treatment, especially for pain management. Following this protocol could enhance FSN skills.

Tuina Therapy for Frozen Shoulders in a Rat Model

Tuina in a Frozen Shoulder Rat Model: An Efficient and Reproducible Protocol

Frozen shoulder (FS) is a common condition with no defined optimal therapy. Tuina therapy, a traditional Chinese medicine (TCM) technique used to treat FS patients in Chinese hospitals, has demonstrated excellent results, but its mechanisms are not fully understood. Building on a previous study, this work aimed to develop a Tuina protocol for an FS rat model. We randomly divided 20 SD rats into control (C; n = 5), FS model (M; n = 5), FS model Tuina treatment (MT; n = 5), and FS model oral treatment (MO; n = 5) groups. This study used the cast immobilization method to establish the FS rat model. The effect of Tuina and oral dexamethasone on the glenohumeral range of motion (ROM) was evaluated, and the histological findings were assessed. Our study showed that Tuina and oral dexamethasone were able to improve shoulder active ROM and preserve the structure of the capsule, with Tuina therapy proving to be more effective than oral dexamethasone. In conclusion, the Tuina protocol established in this study was highly effective for FS.

Intra-articular Shoulder Injection for Reduction Following Shoulder Dislocation

Source: Rachel Liu, BAO, MBBCh, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA
The anterior shoulder dislocation is one of the most common joint dislocations seen in emergency settings. In anterior shoulder dislocation, the humeral head is displaced out of the glenohumeral joint in front of the scapular glenoid, resulting in a loss of the articulation between the arm and the rest of the shoulder. This can be caused by a fall onto an abducted, extended, and externally rotated arm, such as in a bicycle or running accident. Sometimes anterior shoulder dislocation can be due to a minor trauma or even result from rolling over in bed with an externally rotated and stretched overhead arm.
Anterior shoulder dislocation is a painful injury. Patients cannot actively abduct, adduct or internally rotate the shoulder. Reduction of the shoulder is the best form of analgesia and, of course, is necessary to restore arm function. While it is current practice for patients to undergo procedural sedation during the shoulder reduction procedure, the sedatives have serious side effects (cardiac and respiratory depression), and require long stays in the emergency department (ED), dedicated nursing staff, multiple radiographs, and consulting services.
Intra-articular injection with a local anesthetic, such as lidocaine, offers significant pain relief in patients with shoulder dislocations and during the reduction procedure. It is a technically simple procedure that doesn&#39;t require long ED stays or significant hospital resources. The success of the intra-articular anesthesia can be enhanced further by performing the procedure under the guidance of bedside ultrasound, which allows real-time visualization of the needle tip reaching the appropriate area.
