BMC Endocr Disord 2022; 22:227. [PMID: 36096804 PMCID: PMC9465918 DOI: 10.1186/s12902-022-01144-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2022] [Accepted: 08/11/2022] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Diabetes is associated with microvascular and macrovascular complications. Although it is less recognized, diabetes also has an important role in the development of musculoskeletal disorders. Our objective was to evaluate the effect of type 2 diabetes (T2D) on the severity of adhesive capsulitis of the shoulder (AC) and on the efficacy of ultrasound guided hydrodistension treatment. METHODS We conducted a retrospective longitudinal observational study, of patients with AC who underwent ultrasound guided hydrodistension at our Centre. Severity was measured with DASH (Disabilities of Arm, Shoulder and Hand) score and pain was evaluated with a score between 0 and 10. The association of T2D with baseline characteristics of AC, and with outcomes at 6-12 months was analyzed using linear and logistic regression models. RESULTS We evaluated 120 ultrasound guided hydrodistension treatments of AC, 85 in patients without diabetes and 35 in patients with T2D. Patients with diabetes had a higher prevalence of dyslipidemia, hypertension and higher HbA1c values. The average duration of diabetes was 4.8 years (2.0, 7.9). The baseline characteristics of AC were not significantly different between patients with and without diabetes. Patients with T2D relapsed more frequently and required more reinterventions than patients without diabetes (20.0% vs 4.7%, p = 0.008), had higher post-intervention pain scale values [4.0 (0.0-5.0) vs 0.0 (0.0-5.0), p = 0.022] and higher post-intervention DASH score [0.8 (0.0-1.8) vs 0.0 (0.0-0.8), p = 0.038]. CONCLUSION Although baseline characteristics of AC in patients with diabetes were similar to those without diabetes, patients with diabetes had a worse response to treatment, more frequent relapses and a greater need for new interventions.

Manipulation under Anesthesia versus Non-Surgical Treatment for Patients with Frozen Shoulder Contracture Syndrome: A Systematic Review. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:9715. [PMID: 35955074 PMCID: PMC9368476 DOI: 10.3390/ijerph19159715] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Revised: 08/03/2022] [Accepted: 08/05/2022] [Indexed: 06/15/2023]
Abstract
Purpose: To investigate the efficacy of manipulation under anesthesia (MUA) compared to other non-surgical therapeutic strategies for patients with frozen shoulder contracture syndrome (FSCS). Methods: A systematic review of literature was conducted. A literature search was performed in MEDLINE, EMBASE, PEDro, Cochrane Central Library and Scopus. Only randomized controlled trials were included and assessed for critical appraisal through the Cochrane Collaborations tools. Results: Five randomized controlled trials were included. The overall risk of bias (RoB) was high in 4 out of 5 of the included studies. MUA was found to be not superior in terms of reduction of pain and improvement of function when compared to cortisone injections with hydrodilatation (mean regression coefficient MUA −2.77 vs. injection −2.75; 95% CI (−1.11 to 1.15)) and home exercise (mean difference 95% CI: 0.2 (−0.64 to 1.02)) in the short term (3 months), and cortisone injections with hydrodilatation (mean regression coefficient MUA 3.13 vs. injection 3.23; 95% CI (−0.90 to 1.11)) in the long term (>6 months). Moreover, if compared to structured physiotherapy, MUA highlighted a higher Oxford Shoulder Score at final 1-year follow up (mean difference 95% CI: 1.05 (−1.28 to 3.39); p = 0.38). Similar results were obtained for disability, with statistically no significant long-term (>12 months) differences between MUA and home exercise (mean difference 95% CI: 0 (−3.2 to 3.2)) or structured physiotherapy (mean difference 95% CI: −0.50 (−5.70 to 4.70); p = 0.85)). Only two trials reported adverse events. Conclusions: This review suggested that limited and inconsistent evidence currently exists on the efficacy of MUA compared to other non-surgical strategies in the management of patients with FSCS. Future research should focus on clinical trials with higher methodological quality.

[PMID: 35323136 PMCID: PMC9191332 DOI: 10.1097/corr.0000000000002181] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2021] [Accepted: 02/28/2022] [Indexed: 01/31/2023]
Abstract
BACKGROUND Shoulder injury related to vaccine administration (SIRVA) is postulated to be an immune-mediated inflammatory response to a vaccine antigen injected into or near the subacromial bursae or synovium, leading to shoulder pain and dysfunction. The number of studies on this topic is rapidly increasing. Recent comparative studies have reported conflicting conclusions, which suggests that a systematic review of the best-available evidence may be helpful. QUESTIONS/PURPOSES In this systematic review, we asked: What are the (1) clinical characteristics, (2) diagnoses, and (3) management approaches and outcomes reported in association with SIRVA? METHODS A search was performed on October 4, 2021, of the PubMed and Medline databases for studies related to SIRVA. Inclusion criteria were English-language comparative studies, case series, and case reports that involved shoulder pain occurring after vaccination. Studies of exclusively neurologic conditions after vaccination were excluded. Forty-two studies met the eligibility criteria, including three retrospective comparative studies (72 patients and 105 controls), five database case series (2273 patients), and 34 case reports (49 patients). Study quality was assessed for the database case series and retrospective comparative studies using the Methodological Index for Non-randomized Studies tool. RESULTS Among patients in the case reports, the median age was 51 years (range 15-90 years), and 73% (36 of 49) were women. BMI was reported for 24% of patients (12 of 49) in case reports, with a median of 23.5 kg/m2 (range 21-37.2 kg/m2). The most common symptoms were shoulder pain and reduced ROM. The most common diagnoses were shoulder bursitis, adhesive capsulitis, and rotator cuff tears. The most frequent management modalities included physical or occupational therapy, NSAIDs, and steroid injections, followed by surgery, which was generally used for patients whose symptoms persisted despite nonsurgical management. Full resolution of symptoms was reported in 2.9% to 56% of patients. CONCLUSION The association between inflammatory conditions of the shoulder (such as bursitis) and vaccination appears to be exceedingly rare, occurring after approximately 1:130,000 vaccination events according to the best-available comparative study. Currently, there is no confirmatory experimental evidence supporting the theory of an immune-mediated inflammatory response to vaccine antigens. Although the clinical evidence is limited, similar to any bursitis, typical treatments appear effective, and surgery should rarely be performed. Additional research is needed to determine the best injection technique or evaluate alternate injection sites such as the anterolateral thigh that do not involve positioning a needle close to the shoulder.

Abstract
BACKGROUND Claims of shoulder injury now account for half of all claims to the Vaccine Injury Compensation Program. Reports from databases of claims or potential adverse events note a relatively high mean age and high prevalences of rotator cuff tendinopathy and adhesive capsulitis-common shoulder problems that might be incidental to vaccination. Published case reports provide much more detail about individual patients than is available in databases. A review of published cases provides an opportunity for more detailed review of symptoms, diagnoses, pathology, treatment, and prognosis. Such a review can better assess the relative likelihood that pathologies associated with new persistent shoulder symptoms after vaccination are coincidental or unique to and caused by vaccine. QUESTIONS/PURPOSES Regarding published case reports addressing persistent shoulder pain after vaccination: (1) In what proportion of patients was a specific diagnosis made? (2) What diagnoses were most common? (3) Among patients treated nonsurgically, what proportion resolved, and over what time span did they resolve? METHODS In August 2020, we searched PubMed and Embase between 2006 and 2020 using the following search strategy: Search 1: (shoulder dysfunction OR shoulder pain OR shoulder bursitis OR rotator cuff tendonitis OR adhesive capsulitis OR glenohumeral arthritis AND [vaccine OR vaccination OR immunization]); Search 2: (shoulder injury related to vaccine administration or SIRVA). The search was supplemented by reviewing reference lists of identified studies. Inclusion criteria were any detailed report of three or fewer cases involving shoulder pain after vaccine administration. Twenty published reports of 29 patients were identified and assessed by two reviewers independently. One reported glenohumeral joint infection was excluded because the relationship between this type of relatively uncommon, discrete diagnosis and vaccination raises different considerations. We assumed a high risk of bias, although we are not aware of bias assessment tool for case reports. We recorded and summarized patient demographics, symptoms, examination and imaging findings, surgery findings, diagnoses, treatments, and outcomes. Seventy-five percent (21 of 28) of patients were women, with a mean age of 54 ± 19 years. In search of an underlying pathology, at least one diagnostic study was performed in 82% (23 of 28) of patients including radiographs in seven, ultrasound in seven, and MRI in 16 patients (some patients underwent more than one type of imaging). We distinguished specific pathophysiological diagnosis from shoulder pain and stiffness, counted the most common diagnoses among patients a specific diagnosis, and tracked symptom resolution among patients treated nonoperatively. RESULTS A specific diagnosis was made in 57% (16 of 28) of patients. Twelve patients had pain and limitation of motion due to pain but no specific pathological diagnosis. The most common specific diagnoses were rotator cuff tendinopathy (9 of 16) and adhesive capsulitis (4 of 16). Less common specific diagnoses included rotator cuff arthropathy (and rheumatoid arthritis) and suspected septic arthritis with nonspecific synovitis on arthroscopy. One patient had transient MRI signal change in the humeral head, which was interpreted as osteonecrosis that resolved in a manner not typical for that diagnosis. Of the 17 patients treated nonsurgically, 15 reported resolution, and two had incomplete symptom resolution with the mean 6-month evaluation period. CONCLUSION The observation that persistent shoulder pain after vaccination overlaps with common shoulder pathology-both in large databases as well as in more detailed reports of specific patients as analyzed in this review-establishes a high probability of a coincidental rather than a causal association. In the absence of high-quality experimental evidence of vaccine-specific shoulder pathology, in our opinion, it seems safest and healthiest to assume that perceived shoulder injury related to vaccine administration (SIRVA) is due to misinterpretation of new symptoms from established pathology rather than a new, vaccine-specific pathology. LEVEL OF EVIDENCE Level IV, therapeutic study.

Abstract
Frozen shoulder (FS), also known as adhesive capsulitis, is a painful inflammatory fibrotic disease of the glenohumeral joint capsule. While it's frequently self-limiting, patients can be symptomatic for years. The clinical course is often divided into three phases: the freezing phase with predominantly pain, the frozen phase with mainly stiffness, and the thawing phase during which the complaints slowly resolve. Diagnosing FS can be challenging during the freezing phase as the symptoms in this phase are similar to other common shoulder conditions (such as subacromial pain syndrome). Treatment options include analgesia, physical therapy, corticosteroid injections, hydrodilatation, manipulation under anaesthesia, and arthroscopic release. Despite the many treatment options, there is no clear treatment guideline. Based on recent literature, conservative management is indicated as it can provide temporary symptom reduction. Due to significant risk of complications, surgical management should only be considered if patients retain complaints despite long-term conservative therapy.

Does capsular distension and a short period of countertraction improve outcome following manipulation under anesthesia for the treatment of primary adhesive capsulitis of the glenohumeral joint? J Shoulder Elbow Surg 2022; 31:772-781. [PMID: 34619350 DOI: 10.1016/j.jse.2021.08.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Revised: 08/24/2021] [Accepted: 08/29/2021] [Indexed: 02/01/2023]
Abstract
BACKGROUND Despite the fact that primary adhesive capsulitis of the glenohumeral joint is often considered a self-limiting condition, not all patients make a full recovery. Manipulation under anesthesia (MUA) is performed to forcibly rupture the contracted capsule in a controlled manner. However, the technique, timing, and use of additional injections are often debated. In this study, we report the outcomes following the addition of capsular distension and countertraction to MUA as a treatment for adhesive capsulitis. METHODS We performed a retrospective case-cohort study comparing 3 groups: Group 1 underwent MUA alone (n = 54); group 2, MUA with capsular distension (n = 114); and group 3, MUA with capsular distension and countertraction (n = 167). The re-MUA rate, Constant-Murley shoulder (CMS) score, and visual analog scale (VAS) score (for pain) were measured after 6 weeks and 6 months. RESULTS The re-MUA rate fell with the addition of both capsular distension and countertraction: 63% in group 1, 39% in group 2, and 18% in group 3. Patients in group 3 recorded the greatest improvement in the CMS score after 6 weeks (+90% vs. +68% in group 2 and +58% in group 1), with all groups showing improvements compared with before treatment. The only independent risk factor identified for re-MUA was smoking. If a second MUA was performed, the CMS (+67%) and VAS (+61%) scores improved, but at 6 months, the CMS score (74.57 ± 7.6 vs. 83.30 ± 5.5) and VAS score (10.57 ± 1.8 vs. 12.96 ± 1.5) remained inferior to those of patients who only needed a single MUA. DISCUSSION AND CONCLUSION MUA combined with capsular distension and countertraction reduces the need for a second MUA and results in a faster improvement in functional outcome (CMS score) and reduction of pain (VAS score) compared with MUA alone or MUA with capsular distension. The results of this case-cohort study are of clinical relevance because they show that the efficacy of an MUA can be improved through relatively simple adaptations of the treatment protocol.

Abstract
The clinical evidences on acupuncture and moxibustion for the treatment of frozen shoulder were sorted and summarized systematically. The relevant articles of frozen shoulder treated with acupuncture and moxibustion were searched from PubMed, EMbase, Cochrane database of systematic review (CDSR), Cochrane database of controlled trials register (CENTRAL), China national knowledge infrastructure (CNKI), Wanfang, VIP, and Chinese biomedical literature databases (SinoMed), from database inception to May 31, 2021. Using AMSTAR-2, the methodological quality of the included systematic reviews was evaluated. With evidence map, the current status of clinical evidence was summarized on acupuncture and moxibustion in treatment of frozen shoulder. A total of 266 original studies and 6 systematic reviews were included finally. At present, many randomized controlled trials are designed with small sample size and the simple acupuncture and moxibustion therapy is dominant as the intervention, e.g. warm acupuncture, acupuncture with filiform needle, acupotomy and electroacupuncture. The outcomes considered in the current trials focus on clinical effective rate, the score of shoulder pain, the score of shoulder function and the score of quality of life. Most of the studies have shown that acupuncture and moxibustion is advantageous as an adjunctive therapy for frozen shoulder, but its clinical evidence is few in terms of the recurrence rate and safety. Moreover, it needs to improve the evidence quality of the relevant studies on acupuncture and moxibustion for frozen shoulder.

Abstract
INTRODUCTION Frozen shoulder (adhesive capsulitis) is a common painful and functionally-limiting disease affecting around 2% of the population. So far, therapeutic options are limited and often unsatisfactory. Platelet-rich plasma (PRP) has been used as a treatment option in other orthopedic diseases since it contains growth factors that stimulate tissue repair. So far, the effect of PRP on frozen shoulder lacks evidence. We hypothesized that PRP may be valuable in the prophylaxis and treatment of secondary frozen shoulder due to capsular remodeling. MATERIALS AND METHODS An experimental study of an in vivo frozen shoulder model was conducted. Twenty Sprague-Dawley rats underwent surgery in which the body of the scapula was connected to the humerus with a high-strength suture. Two groups of 8 weeks survival time were allocated; a treatment group with one intraoperative injection of PRP into the glenohumeral joint (n = 10) and a control group without PRP (n = 10). The primary outcome was the structural change in the posterior synovial membrane of the posterior and inferior part of the glenohumeral joint using a semi-quantitative grading from 0 (lowest) to 3 (highest). RESULTS The posterior synovial membrane structural changes were significantly lower in the PRP group (median = 1 [interquartile range (IQR) = 0-1]) compared to controls (median = 2 [IQR = 1-3]) (p = 0.028). There were no differences for the remaining synovial membrane changes and fibrous capsule responses between groups. CONCLUSIONS In this in vivo shoulder contracture model, PRP injections seem to reduce the histological severity grade of some parts (i.e., posterior synovial membrane changes) of the secondary frozen shoulder without causing any side effects. It may be considered to investigate this effect further in future studies as a potential prophylaxis of secondary frozen shoulder (e.g., in operated or immobilized shoulders) or as a treatment option for patients with frozen shoulder in the early stage.

Abstract
ABSTRACT Adhesive capsulitis, a common primary care and orthopedic diagnosis often referred to as frozen shoulder, is a painful inflammatory process that leads to a mechanical block in active and passive range of shoulder motion. Risk factors include diabetes and thyroid dysfunction. Diagnosis is made based on physical examination, but can be augmented by diagnostic imaging. Nonsurgical management is the mainstay of treatment because the disease is self-limiting. However, some patients may need surgical intervention.

Abstract
Currently, there is limited evidence to guide treatment and no standard management guidelines exist for treating frozen shoulder (FS). A general management approach consists of initial evaluation, range of motion (ROM) exercises, intra-articular injection of glucocorticoid, home exercise program (HEP), and/or physical therapies. However, the general approach lacks detail and has limited evidence of its effectiveness. This retrospective cohort study evaluates the short-term recovery of near-full to full-ROM technique followed by an instructed HEP for strengthening and coordinating shoulder girdle muscle group for FS management. This study details our experiences following a general approach to managing FS and aims to fill this knowledge void, providing additional context of the efficacy of FS management in the real-world. Seven-two adult patients with FS (46 females, 26 males; mean age of 66; standard deviation of 15.1; range 23-87) from an orthopedic and physical medicine and sport medicine office between 2014 and 2018 were included in this study. Following general management of FS, patients received a glucocorticoid-lidocaine mixture injection administered to the respective shoulder at the glenohumeral joint space and/or subacromial separately. Immediately, patients underwent active manipulation of the affected shoulder in 3 directions: forward flexion, abduction, and extension in the sagittal plane. Lastly, patients were instructed to perform movements similar to the active manipulation protocol as a HEP. The abduction and forward flexion ROM showed significant improvements with the described protocol. Following treatment, there was a 90.20° and 77.33° increase in average shoulder abduction and forward flexion ROM, respectively (P < .05). The immediate goal of this protocol was to gain maximum ROM in different directions of shoulder mobility. Following the general management of FS, active manipulation under local anesthetic was a highly effective treatment modality for adhesive capsulitis that was time-saving and cost-effective.

Abstract
OBJECTIVE To compare the combination of corticosteroid injection and physiotherapy with physiotherapy alone in patients of frozen shoulder in terms of SPADI score. METHODS This study included 80 patients of either gender from PMC and affiliated hospitals of Faisalabad with ages between 18-55 years having frozen shoulder of either gender with more than 1 month duration. Patients having frozen shoulder secondary to trauma, cerebrovascular accident and taking steroid injections were excluded. Combination of corticosteroid injection and physiotherapy was performed in combination therapy group (n=40) and physiotherapy alone was performed in Single therapy group (n=40). RESULTS A total of 80 patients, 30(37.5%) males and 50(62.5%) females were selected for the study. Each group, combination therapy and single therapy had 40 patients each. The combination therapy group included 18(45.0%) males and 22(44.0%) females whereas the single therapy group comprised of 12(39.9%) males and 28(70%) females. The treatment method was independent of duration of disease (p= 0.251 for c2= 1.317). After six weeks of treatment, the t-test applied on SPADI score showed that combined treatment is better than the single treatment method (p= 0.016). However, both treatment methods were found same after stratification of duration of disease. CONCLUSIONS Combination of corticosteroid injection and physiotherapy is more effective than the physiotherapy alone in resolving the shoulder pain and disability of shoulder.

Abstract
Musicians comprise a specific occupational group with high musculoskeletal loads as well as demands. A frozen shoulder, or adhesive capsulitis, is a common musculoskeletal condition characterized by pain and loss of function of the glenohumeral joint. Despite being described as a generally self-limiting condition, the clinical course of the disease is unclear. A frozen shoulder can be a career-threatening diagnosis for musicians who need a wide range of motion of the shoulder to play their instruments. The aim of this narrative review is to provide healthcare providers and musicians with an overview of treatment principles for instrumental musicians with frozen shoulder. In this review, both general treatment principles as well as instrument-specific ergonomic tools are discussed. The aim is to provide an overview of the available tools to preserve a musician's playing capabilities and to enable early return to playing the instrument.

Abstract
BACKGROUND To our knowledge, there have been no published clinical trials to assess the synergistic effects of applying pulsed radiofrequency (PRF) stimulation of the suprascapular nerve (SSN) plus physical therapy on pain and function in patients with adhesive capsulitis. Therefore, we will conduct this present randomized, double-blind study to evaluate the synergistic effects of applying PRF stimulation of the SSN plus physical therapy on pain and function in patients with adhesive capsulitis. METHODS The study protocol is a randomized, controlled, double-blind design. Recruitment will be started in March 2021 and completed in October 2022. The treating surgeon will assess 90 patients for eligibility. The study protocol was approved through Institutional Review Board in the People's Hospital of Beilun district of Ningbo. Each patient will be randomized into 3 treatment groups, receiving PRF stimulation of the SSN or physical therapy or both of them. After baseline examination, all patients will be given a full explanation of the treatment protocol and will be required to sign a written informed consent for study participation and for publication of the results. All the data collectors, surgeons, statistical analysts, as well as result assessors are not aware of grouping assignment. The outcomes include Constant score, visual analog scale score, range of motion, and strength. RESULTS This protocol will provide a reliable theoretical basis for the following research. CONCLUSION It is assumed that there will be a remarkable difference in postoperative outcomes between the intervention and control groups. TRIAL REGISTRATION NUMBER 10.17605/OSF.IO/PZ9ES.

Abstract
Manipulation under anesthesia (MUA) combined with intra-articular steroid injection (ISI) is preferred in management of the refractory frozen shoulder (FS). This study aimed to evaluate the effect of MUA with ISI or not on pain severity and function of the shoulder.Data on 141 patients receiving MUA with primary FS refractory to conservative treatments for at least 1 month were retrospectively obtained from medical records. We performed propensity score matching analysis between patients receiving MUA only and those receiving MUA plus ISI, and then conducted logistic regression analysis to identify the risk factors for the need to other treatments during 6-month follow-up.More improvement in terms of the SPADI pain scores and passive ROM at 2 weeks after first intervention remained in patients receiving MUA plus ISI after matching. The need to other treatments during 6-month follow-up occurred in 10.6% patients (n = 141). Logistic regression analysis revealed that a repeat MUA 1 week after first intervention was a protective factor (OR 0.042; 95% CI 0.011-0.162; P = .000) and duration of disease was the only one risk factor (OR 1.080; 95% CI 1.020-1.144; P = .008) for the need to other treatments during follow-up.ISI immediately following MUA provided additional benefits in rapid relief of pain and disability for patients with refractory FS. Pain and disability of the shoulder may be rapidly alleviated by an earlier MUA from the onset of the symptoms and a repeat MUA 1 week after first intervention.

Abstract
PURPOSE To assess the angiographic findings and the effects of transcatheter arterial embolization on physical activity and histopathology using a frozen shoulder rat model. MATERIALS AND METHODS First, the angiographic and histopathologic findings of rats in which the shoulder was immobilized with molding plaster for 6 weeks (n = 4) were compared to control rats with normal non-immobilized shoulders (n = 4). Next, a total of 16 frozen shoulder rats were divided into 2 groups. In the transcatheter arterial embolization group (n = 8), imipenem/cilastatin was injected into the left thoracoacromial artery. The changes of physical activity before and after procedures were evaluated and compared with a saline-injected control group (n = 8). Histopathologic findings were also compared between the 2 groups. RESULTS Angiography revealed abnormal shoulder staining in all of the rats with a frozen shoulder. On histopathology, the numbers of microvessels and mononuclear inflammatory cells in the synovial membrane of the joint capsule were significantly higher compared with the control rats (both P = .03). In the transcatheter arterial embolization group, the running distance and speed were improved (P = .03 and P = .01, respectively), whereas there were no significant differences in the control group. The number of microvessels and mononuclear inflammatory cells in the transcatheter arterial embolization group were significantly lower than the control group (P = .002 and P = .001, respectively). CONCLUSIONS The rat frozen shoulder model revealed the development of neovascularization. Transcatheter arterial embolization decreased the number of blood vessels and inflammatory changes in the frozen shoulder and increased the moving distance and speed of the rats.

Abstract
Purpose Adhesive capsulitis of the hip (ACH) is likely that this condition had been previously encountered, but easily unrecognised. We investigated the clinical features of patients with ACH, the efficacy of ultrasound-guided intra-articular hydrodilatation, and the patients’ prognosis. Methods We enrolled 84 patients (93 hips) who visited the outpatient clinic from August 2018 to November 2019. ACH was diagnosed by restricted range of motion and sharp pain when turning with the affected leg fixed on the ground. We evaluated patient demographics and associated intra-articular pathologies found on magnetic resonance angiography (MRA) images. Injections were performed twice at two week intervals with a mixture of 0.5% lidocaine (25 mL) and triamcinolone (40 mg; 1 mL) with capsular distension under ultrasound guidance. Patients were assessed before and after treatment using a visual analogue scale (VAS), hip disability and osteoarthritis outcome score (HOOS), hip range of motion (ROM), and distance from floor to knee (DFK) when sitting in the cross-legged position. Results On MRA, 18 patients had abnormal findings (eight labral tears, seven abductor tendinosis, three primary arthrosis). The mean VAS decreased from 7.1 ± 1.1 to 0.8 ± 0.9 after the last injection, and the HOOS improved in all subsets. The mean DFK decreased from 17.9 ± 4.8 to 9.7 ± 2.8 cm, and passive ROM showed improvement, especially in flexion and rotation. In seven patients, symptom recurrence was reported a mean of 4.1 months after the latest injection, but no independent risk factor for recurrence was identified. Conclusion Based on these current observations, patients with ACH may receive relief from hip joint pain and experience improved function with a timely diagnosis and effective treatment.

Abstract
IMPORTANCE There are a myriad of available treatment options for patients with frozen shoulder, which can be overwhelming to the treating health care professional. OBJECTIVE To assess and compare the effectiveness of available treatment options for frozen shoulder to guide musculoskeletal practitioners and inform guidelines. DATA SOURCES Medline, EMBASE, Scopus, and CINHAL were searched in February 2020. STUDY SELECTION Studies with a randomized design of any type that compared treatment modalities for frozen shoulder with other modalities, placebo, or no treatment were included. DATA EXTRACTION AND SYNTHESIS Data were independently extracted by 2 individuals. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. Random-effects models were used. MAIN OUTCOMES AND MEASURES Pain and function were the primary outcomes, and external rotation range of movement (ER ROM) was the secondary outcome. Results of pairwise meta-analyses were presented as mean differences (MDs) for pain and ER ROM and standardized mean differences (SMDs) for function. Length of follow-up was divided into short-term (≤12 weeks), mid-term (>12 weeks to ≤12 months), and long-term (>12 months) follow-up. RESULTS From a total of 65 eligible studies with 4097 participants that were included in the systematic review, 34 studies with 2402 participants were included in pairwise meta-analyses and 39 studies with 2736 participants in network meta-analyses. Despite several statistically significant results in pairwise meta-analyses, only the administration of intra-articular (IA) corticosteroid was associated with statistical and clinical superiority compared with other interventions in the short-term for pain (vs no treatment or placebo: MD, -1.0 visual analog scale [VAS] point; 95% CI, -1.5 to -0.5 VAS points; P < .001; vs physiotherapy: MD, -1.1 VAS points; 95% CI, -1.7 to -0.5 VAS points; P < .001) and function (vs no treatment or placebo: SMD, 0.6; 95% CI, 0.3 to 0.9; P < .001; vs physiotherapy: SMD 0.5; 95% CI, 0.2 to 0.7; P < .001). Subgroup analyses and the network meta-analysis demonstrated that the addition of a home exercise program with simple exercises and stretches and physiotherapy (electrotherapy and/or mobilizations) to IA corticosteroid may be associated with added benefits in the mid-term (eg, pain for IA coritocosteriod with home exercise vs no treatment or placebo: MD, -1.4 VAS points; 95% CI, -1.8 to -1.1 VAS points; P < .001). CONCLUSIONS AND RELEVANCE The findings of this study suggest that the early use of IA corticosteroid in patients with frozen shoulder of less than 1-year duration is associated with better outcomes. This treatment should be accompanied by a home exercise program to maximize the chance of recovery.

Abstract
BACKGROUND Frozen shoulder causes pain and stiffness. It affects around 10% of people in their fifties and is slightly more common in women. Costly and invasive surgical interventions are used, without high-quality evidence that these are effective. OBJECTIVES To compare the clinical effectiveness and cost-effectiveness of three treatments in secondary care for adults with frozen shoulder; to qualitatively explore the acceptability of these treatments to patients and health-care professionals; and to update a systematic review to explore the trial findings in the context of existing evidence for the three treatments. DESIGN This was a pragmatic, parallel-group, multicentre, open-label, three-arm, randomised superiority trial with unequal allocation (2 : 2 : 1). An economic evaluation and a nested qualitative study were also carried out. SETTING The orthopaedic departments of 35 hospitals across the UK were recruited from April 2015, with final follow-up in December 2018. PARTICIPANTS Participants were adults (aged ≥ 18 years) with unilateral frozen shoulder, characterised by restriction of passive external rotation in the affected shoulder to < 50% of the opposite shoulder, and with plain radiographs excluding other pathology. INTERVENTIONS The inventions were early structured physiotherapy with a steroid injection, manipulation under anaesthesia with a steroid injection and arthroscopic capsular release followed by manipulation. Both of the surgical interventions were followed with post-procedural physiotherapy. MAIN OUTCOME MEASURES The primary outcome and end point was the Oxford Shoulder Score at 12 months post randomisation. A difference of 5 points between early structured physiotherapy and manipulation under anaesthesia or arthroscopic capsular release or of 4 points between manipulation under anaesthesia and arthroscopic capsular release was judged clinically important. RESULTS The mean age of the 503 participants was 54 years; 319 were female (63%) and 150 had diabetes (30%). The primary analyses comprised 473 participants (94%). At the primary end point of 12 months, participants randomised to arthroscopic capsular release had, on average, a statistically significantly higher (better) Oxford Shoulder Score than those randomised to manipulation under anaesthesia (2.01 points, 95% confidence interval 0.10 to 3.91 points; p = 0.04) or early structured physiotherapy (3.06 points, 95% confidence interval 0.71 to 5.41 points; p = 0.01). Manipulation under anaesthesia did not result in statistically significantly better Oxford Shoulder Score than early structured physiotherapy (1.05 points, 95% confidence interval -1.28 to 3.39 points; p = 0.38). No differences were deemed of clinical importance. Serious adverse events were rare but occurred in participants randomised to surgery (arthroscopic capsular release,n = 8; manipulation under anaesthesia,n = 2). There was, however, one serious adverse event in a participant who received non-trial physiotherapy. The base-case economic analysis showed that manipulation under anaesthesia was more expensive than early structured physiotherapy, with slightly better utilities. The incremental cost-effectiveness ratio for manipulation under anaesthesia was £6984 per additional quality-adjusted life-year, and this intervention was probably 86% cost-effective at the threshold of £20,000 per quality-adjusted life-year. Arthroscopic capsular release was more costly than early structured physiotherapy and manipulation under anaesthesia, with no statistically significant benefit in utilities. Participants in the qualitative study wanted early medical help and a quicker pathway to resolve their shoulder problem. Nine studies were identified from the updated systematic review, including UK FROST, of which only two could be pooled, and found that arthroscopic capsular release was more effective than physiotherapy in the long-term shoulder functioning of patients, but not to the clinically important magnitude used in UK FROST. LIMITATIONS Implementing physiotherapy to the trial standard in clinical practice might prove challenging but could avoid theatre use and post-procedural physiotherapy. There are potential confounding effects of waiting times in the trial. CONCLUSIONS None of the three interventions was clearly superior. Early structured physiotherapy with a steroid injection is an accessible and low-cost option. Manipulation under anaesthesia is the most cost-effective option. Arthroscopic capsular release carries higher risks and higher costs. FUTURE WORK Evaluation in a randomised controlled trial is recommended to address the increasing popularity of hydrodilatation despite the paucity of high-quality evidence.
