Aims. The primary aim of this study was to assess the feasibility of recruiting and retaining patients to a patient-blinded randomized controlled trial comparing corticosteroid injection (CSI) to autologous protein solution (APS) injection for the treatment of subacromial shoulder pain in a community care setting. The study focused on recruitment rates and retention of participants throughout, and collected data on the interventions’ safety and efficacy. Methods. Participants were recruited from two community musculoskeletal treatment centres in the UK. Patients were eligible if aged 18 years or older, and had a clinical diagnosis of subacromial impingement syndrome which the treating clinician thought was suitable for treatment with a subacromial injection. Consenting patients were randomly allocated 1:1 to a patient-blinded subacromial injection of CSI (standard care) or APS. The primary outcome measures of this study relate to rates of recruitment, retention, and compliance with intervention and follow-up to determine feasibility. Secondary outcome measures relate to the safety and efficacy of the interventions. Results. A total of 53 patients were deemed eligible, and 50 patients (94%) recruited between April 2022 and October 2022. Overall, 49 patients (98%) complied with treatment. Outcome data were collected in 100% of participants at three months and 94% at six months. There were no significant adverse events. Both groups demonstrated improvement in patient-reported outcome measures over the six-month period. Conclusion. Our study shows that it is feasible to recruit to a patient-blinded randomized controlled trial comparing APS and CSI for subacromial pain in terms of clinical outcomes and health-resource use in the UK. Safety and efficacy data are presented. Cite this article: Bone Jt Open 2024;5(7):534–542

Introduction

The conservative management of Sub-Acromial Impingement Syndrome (SAIS) of the shoulder includes both physiotherapy treatment and subacromial injection with local anaesthetic and steroids. The outcome from injection treatment has rarely been evaluated scientifically.

Subacromial corticosteroid injection has been shown to be effective in treating impingement syndrome. The exact mechanism of action is not clear but it may be due to its anti-inflammatory properties. However, there are potential side effects of steroid injection including tendon weakening, dermal atrophy and infection. NSAIDs may offer similar anti-inflammatory properties but without the side effects of corticosteroids. Tenoxicam is a long-acting water soluble NSAID and is available without irritant preservatives. Studies have shown that peri-articular Tenocixam injection was useful in treating painful shoulders and local tolerability was good. The aim of this study is to carry out a blinded ran-domised controlled study comparing subacromial Tenoxicam injection (NSAID) against methylprednisolone (steroid) injection in patients with clinical subacromial impingement syndrome. The study protocol was approved by local research ethics committee. Patients over 18 with a clinical diagnosis of subacromial impingement syndrome were considered eligible to this study. Patients with other known causes of shoulder pain, contraindication or sensitivity to NSAID and pregnant patients were excluded. Three functional outcome measures were used – Constant-Murley Shoulder Score, DASH and the Oxford Shoulder Score. The patients completed all three outcome measures before and 2, 4 and 6 weeks after the subacromial injection. Simple randomisation method was used and blinded to both researcher and the patient. 58 patients randomised into two groups were reviewed at the end of six weeks. Patients treated with subacromial steroid injection had a much better outcome compared to patients treated with subacromial tenoxicam injection and this difference was highly significant (p< .003). In conclusion, patients with subacromial impingement syndrome have a better clinical outcome when treated with subacromial steroid injection than NSAID injection

To assess the value of physiotherapy in the treatment of patients with subacromial impingement syndrome. Patients with subacromial impingement syndrome were identified. Those who had not previously had any physiotherapy and had failed to respond to non-surgical management were selected and placed on the waiting list for subacromial decompression. Patients were randomised into two groups. One group was referred for physiotherapy while waiting for surgery. The control group had no intervention prior to surgery. The patients in the physiotherapy arm underwent assessment and treatment by a single physiotherapist. All patients were evaluated independently at 3 and 6 months. The Constant Score was used to assess all patients initially and at each visit. Physiotherapy group: All patients (n=42) increased their Constant score. 11 of the 42 patients improved to an extent that surgery was no longer required (26%). In patients not requiring surgery, the mean improvement in Constant score was 25 (12–45) In patients requiring surgery (n=31), the mean improvement was 21 (3–34). Patients not requiring surgery had a higher initial Constant score, 65 (30–84) than those requiring surgery 48 (17–59). Patients not requiring surgery also tended to be younger 52 (27–68) than those requiring surgery 59 (48–68). Control group: All patients (n=23) went on to have surgery. The mean improvement in Constant score was 2 (−16 to 12). All patients with subacromial impingement syndrome improved with physiotherapy when compared to a control group that did not receive physiotherapy. Some patients in the physiotherapy group improved to the extent that surgery was no longer required (26%)

Aim: To assess the value of physiotherapy in the treatment of patients with subacromial impingement syndrome. Methods: Patients with subacromial impingement syndrome were identified. Those who had not previously had any physiotherapy and had failed to respond to other types of non-surgical management were selected and placed on the waiting list for subacromial decompression. These patients were randomised into two groups. One group was referred for physiotherapy while waiting for surgery. The control group had no intervention prior to surgery. The patients in the physiotherapy group underwent an assessment and treatment by a single physiotherapist. All patients were evaluated independently after each of three and six months. The Constant Score was used to assess all patients initially and at each visit. Results: Physiotherapy group: All patients (n=42) increased their Constant score. Eleven of the 42 patients (26%) improved to an extent that surgery was no longer required. In patients not requiring surgery, the mean improvement in the Constant score was 25 (range: 12 to 45) In the patients requiring surgery, (n=31), the mean improvement was 21 (range: three to 34). Patients not requiring surgery had a higher initial Constant score, 65 (range: 30–84) than those requiring surgery 48 (range: 17 to 59). Patients not requiring surgery also tended to be younger 52 (range: 27 to 68) than those requiring surgery 59 (range: 48 to 68). Control Group: All patients (n=23) went on to have surgery. The mean improvement in Constant score was two (Range: −16 to 12). Conclusions: All patients with subacromial impingement syndrome improved with physiotherapy when compared with a control group that did not receive physiotherapy. Some patients in the physiotherapy group (26%) improved to the extent that surgery was no longer required

Background: The aim of this study is to evaluate the efficacy of extracorpereal shock wave therapy (ESWT) in some of most frequent muscularskeletal pathologies. Material and methods: From July to October 2004 310 patients were treated with ESWT, suffering from the following pathologies: 96 symptomatic calcific tendonitis of the shoulder, 53 symptomatic sub-acromial impingement, 48 humeral epichondylitis, 52 plantar fasciitis, 24 pertrochanteric bursitis, 15 Achilleous tendinopathy and 22 patellar tendinopathy. Patients were evaluated clinically and instrumentally before the first application and at one and three months of follow-up. Three disability scales we utilized (NRS, Mcgill Pain Questionnaire e Chronic Pain Grade Questionnaire). Results: We observed a reduction of the pain and an increase of the articular functionality in 83% of calcific tendonitis of the shoulder, in 55% of sub-acromial impingement, in 76% of epichondylitis, in 74% of palantar fasciitis, in 90% of pertrochanteric bursitis, in 82% of Achilleous tendinopathy and in 86% of patellar tendinopaty. Discussion: The data confirm the therapy with ESWT is efficient in some of most frequent musculoskeletal pathologies, with variable outcome in the various pathologies under investigation

Purpose: To evaluate the use of a steroid and local anaesthetic subacromial injection as a prognostic tool for patient recovery following arthroscopic subacromial decompression (ASD). Methods: A prospective study of all patients seen in our unit with a clinical diagnosis of subacromial impingement syndrome was carried out between 1/00 and 9/01. All patients were diagnosed clinically, followed by a local anaesthetic/steroid subacromial injection test. In the event of a negative result to the injection test, the diagnosis was confirmed by CT arthrography or MRI scanning. All patients underwent standard ASD, with clinical evaluation via the Constant score preoperatively, at 3 weeks, 3 months, and at discharge. The eventual functional outcome was correlated with the results of the impingement test and the operative findings. Results: One hundred and one patients (53 male, 48 female), with a mean age of 52 years (range 21–77) were entered into the study. Patients were followed up for a mean of 14 months (range 3–24). All patients had an impingement lesion noted at arthroscopy. The mean preoperative Constant score for the entire group was 48 (20–67) with a postoperative mean of 81 (46–98). 16 patients had a negative preoperative injection test. The mean improvement in this group was 21 points (47 rising to 68) compared to 35 points (48 to 83) in the positive group (p< 0.05, Mann-Whitney U test). The groups were otherwise similar for age, sex and operative findings. Conclusions: The subacromial injection test is a useful tool both diagnostically and prognostically in patients with subacromial impingement syndrome. In patients with a confirmed diagnosis but a negative test there is still a significant improvement in the post operative Constant score, but this is of a lesser degree than in those with a positive injection test. This does not appear to be related to age, impingement grade or cuff tears, and may represent a true difference in the underlying pathology

Aims

Steroid injections are used for subacromial pain syndrome and can be administered via the anterolateral or posterior approach to the subacromial space. It is not currently known which approach is superior in terms of improving clinical symptoms and function. This is the protocol for a randomized controlled trial (RCT) to compare the clinical effectiveness of a steroid injection given via the anterolateral or the posterior approach to the subacromial space.

Background. Shoulder impingement syndrome (SIS) is a common debilitating condition, treated across multiple health disciplines including Orthopaedics, Physiotherapy, and Rheumatology. There is little consistency in diagnostic criteria with ‘Shoulder impingement syndrome’ being used for a broad spectrum of complex pathologies. We assessed patterns in diagnostic procedures for SIS across multiple disciplines. Methods. This is a systematic review of electronic databases MEDLINE, PubMed, The Cochrane Library, Embase, Scopus and CINAHL five years of publications, January 2009 - January 2014. Search terms for SIS included subacromial impingement syndrome, subacromial bursitis. Searches were delimited to articles written in English. The PRISMA guidelines were followed. Two reviewers independently screened all articles, data was then extracted by one reviewer and twenty percent of the extraction was independently assessed by the co-reviewer. Studies included were intervention studies examining individuals diagnosed with SIS and we were interested in the process and method used for the diagnosis. Results. The search strategy yielded 3339 articles of which 1931 were duplicates. A further 1260 were excluded based on relevance obtained from title/abstract. A total of 148 articles were identified investigating SIS across thirty different journals internationally. Fourteen different health disciplines have investigated twenty-five different surgical and conservative treatments. Studies document their diagnostic approach, reporting on duration of symptoms, medical history, physical examination tests and radiological investigations. Duration of symptoms for inclusion ranged from a minimum of 2 weeks to 18 months where the median duration of symptoms is 3 months observed in 46 percent of the studies. Commonly used physical tests were Neer's test, Hawkins-Kennedy test, Jobe and Yocum, and a further eight tests identified. Neer's test or Hawkins-Kennedy tests were individually used in 72 percent of studies. Thirty of the studies used more than one and up to six physical tests per study to determine the presence of impingement. Radiological investigations were reported in twenty-eight studies, sixteen of these required more than one radiological investigation to confirm the diagnosis of SIS. Comparisons between disciplines identify important differences in diagnostic criteria used by different health professionals. Conclusions. This study highlights the variety of diagnostic methods which are currently used between health disciplines and will be a useful comparative tool for clinicians. Diagnostic transparency is pertinent for shoulder impingement syndrome to ensure all disciplines are treating the same pathology and importantly to contribute to our understanding of the common pathology

68 patients underwent arthroscopic subacromial decompression for shoulder impingement syndrome. Patients were evaluated preoperatively, at 3 weeks and 3 months post operatively using the Constant score. Mean preoperative Constant score was 46. 5 (34–67), at 3 weeks 65. 8 (40–86), and at 3 months 82. 4 (50–99). There was no correlation between the impingement grade, presence of a cuff tear or acromioclavicular joint involvement, and a significant poorer outcome. Arthroscopic subacromial decompression is a reliable method of improving the functional ability of patients with subacromial impingement syndrome, with a 20 point increase in the Constant score at 3 weeks post surgery, rising to a 40 point increase at 3 months. Patients can therefore be counselled that they will make a significant functional improvement in a short time after surgery

Intra-articular shoulder pathology has been recognised in more detail following widespread use of shoulder arthroscopy. The purpose of this epidemiological study is to present the incidence and exact type of SLAP lesions in our operated population and to correlate them with the presence of other shoulder lesions. Between 2004 and 2010 425 patients underwent shoulder arthroscopy in our department (311 for rotator cuff tears or subacromial impingement, 102 for shoulder instability, 12 for SLAP lesions). Eighty-two SLAP lesions (19.2% overall) were recognized during these procedures. In 44 cases the lesion was SLAP type I (53.6%), in 10 type II (12.2%), in 1 type III (1.2%), in 1 type IV (1.2%), in 24 type V (29.26%) and finally in 2 type VI (2.43%). In more detail SLAP I lesions were associated in 8 patients with subacromial impingement syndrome, in 33 with RC tear and in 3 patients with anterior instability. Type II, III and IV were preoperatively diagnosed, while type V and VI lesions were found in patients with chronic anterior shoulder instability. SLAP lesions are diagnosed more accurately during shoulder arthroscopy rather than with plain shoulder MRI scan. In our study population only 12 cases were accurately diagnosed with a pre-operative MRI scan, while the remaining 70 cases were missed. Additionally, there was significant correlation between rotator cuff problems and SLAP I lesions, while chronic shoulder instability was associated with SLAP V and VI (25.4% of patients with instability). Shoulder arthroscopy not only has changed SLAP lesion diagnosis and treatment but also reveals the correlation of various SLAP lesion types with specific shoulder pathologies

Introduction. There are over 110 special tests described in the literature for clinical examination of the shoulder, but there is no general consensus as to which of these are the most appropriate to use. Individual opinion appears to dictate clinical practice. Rationalising which tests and clinical signs are the most useful would not only be helpful for trainees, but would also improve day to day practice and promote better communication and understanding between clinicians. Methodology. We sent a questionnaire survey to all shoulder surgeons in the UK (BESS members), asking which clinical tests each surgeon found most helpful in diagnosing specific shoulder pathologies; namely sub-acromial impingement, biceps tendonitis, rotator cuff tears and instability; both anterior and posterior. Results. For impingement; Hawkins-Kennedy and Neer's tests were used by the majority of respondents, with 50% also routinely performing Neer's injection test. For frozen shoulder; the shoulder quadrant test was the commonest used, followed by loss of passive range of motion and loss of external rotation. For biceps tendonitis; Speed's and Yergason's tests were by far the commonest used. For rotator cuff tears the commonest signs were; the Napoleon belly press, Hornblower's sign, Gerber's sign, Jobe's sign and Codman's drop arm sign. For instability; the apprehension test, the Gerber-Ganz drawer test, load and shift test and Jobe's relocation test were the commonest used, with the jerk test also popular for posterior instability. We are also currently assessing how individuals actually perform these tests, and whether they are as the original authors described them. Conclusion. Our results demonstrated some variation in which tests were being used, but with an increased preference for certain tests. Interestingly a large number of respondents commented that the history was of paramount importance and that clinical signs should only substantiate the clinician's diagnosis

Aims: The purpose of this study was to verify a partial bursal-side rupture of the rotator cuff (RC) using different imaging techniques with special emphasis on the validity of a specific method of subacromial arthrography (SAA). Methods: Patients (n=92, age 53.8 years) with a subacromial impingement syndrome underwent sonography, magnetic resonance imaging (MRI), and SAA. All diagnostic results were controlled by subsequent arthroscopic surgery. Results: Out of 31 surgically verified ruptures, 17 cases showed a partial rupture located towards the bursa. These had been detected by MRI and ultrasound with a sensitivity of 64% and 41%, respectively, while SAA as a diagnostic tool yielded a sensitivity of 82%. In 14 cases of complete RC ruptures, all imaging techniques had a similar sensitivity of 86 to 93%. Conclusions: It appears that SAA is a sufficient and valid diagnostic tool for the detection of partial bursa-sided RC ruptures. Ultrasound and MRI showed a comparably lower sensitivity. It is therefore concluded that SAA has clear advantages in the diagnosis of this defect with the consequence that open surgical techniques to the patient can be avoided

Purpose: Subacromial impingement syndrome is a painful condition which occurs during overhead activities as the rotator cuff is compressed between the greater tuberosity and the acromion. Unrecognized secondary causes of impingement syndrome may lead to treatment failure. Posterior capsular tightness, believed to alter shoulder joint kinematics, is often cited as a secondary cause but scientific evidence is lacking. The objective of this study was to evaluate the effect of posterior capsular tightness on pressure in the subacromial space. Method: Ten fresh-frozen cadaver shoulder specimens were mounted on a custom testing apparatus. With the scapula fixed, the deltoid and cuff muscles were loaded statically with a constant ratio to elevate the humerus in the scapular plane under physiologic loading conditions. For each treatment (intact capsule, 1cm and 2cm plication), pressure in the subacromial space and glenohumeral kinematics were recorded during elevation. The treatment order was randomly assigned to each specimen. Peak pressure and translation of the humeral head center were compared using a repeated measures ANOVA. Results: Peak subacromial pressures (mean±sd) were similar between treatment groups: 345±152 kPa, 410±213 kPa and 330±164 kPa for the intact, 1cm and 2cm plication respectively (p> 0.05). No significant differences were found for superior or antero-posterior translations of the humeral head at the peak pressure position (p> 0.05). Conclusion: Posterior capsular tightness, as a sole variable, did not contribute significantly to increased pressure in the subacromial space or to increased anterior or superior humeral head translation during abduction. Clinically, posterior capsular tightness may occur in association with impingement syndrome but may not play a significant role in causation

Purpose: Appropriate treatment of full-thickness tears of the rotator cuff with subacromial impingement remains a subject of debate. Considering that in most patients, spontaneous tears of the long biceps tendon reduces the pain and that subacromial osteoarthritis is well tolerated by many patients, we proposed arthroscopic tenotomy of the long biceps in this indication with the aim of relieving pain. We report here the long-term outcome. Material and methods: Between 1988 and 1999, 307 arthroscopic tenotomies of the long biceps tendon were performed in patients with unrepairable tears of the rotator cuff tendons (massive full thickness tears, old patients, non-motivated patients). The procedure was isolated in 64% and associated with acromioplasty in 36%. All patients were given prior medical treatment. Mean age at surgery was 64.3 years. The preoperative subacromial height was 6.6 mm. The tendon lesion was an isolated tear of the supraspinatus in 31%, tears of two tendons in 44.6% and tears of three tendons in 21.8%, and isolated tears of the subscapularis in 2.6%. Mean follow-up was 57 months (24–168). Results: The Constant score improved from 48.4 to 67.6 points (p< 0.001). Glenohumeral osteoarthritis (Samilson) increased from 38% to 67% of the shoulders postoperatively. Association with acromioplasty improved the objective and subjective result solely in the group of isolated tears of the supraspinatus. The size of the tear and the degree of fatty degeneration of the rotator cuff muscles had a statistically significant influence on functional and radiographic outcome (p< 0.001) while time since surgery had no effect on radiographic outcome (p< 0.001). Discussion: This simple easy-to-perform procedure yielded pain relief at rest and also nighttime pain. It can be recommended for massive rotator cuff tears with sub-acromial impingement in elderly or poorly-motivated patients whose pain fails to respond to medical treatment. This procedure does not allow recovery of shoulder motion or force

Purpose: To present our experience in the treatment of sub-acromial impingement by the method of arthroscopic acromioplasty. Material – Method: This study includes 41 patients (17 males and 24 females) with average age 53.07 years (range 22 – 69). All patients were suffering from intense pain in the shoulder joint and presented movement limitation. The patients were evaluated clinically and with plain Xrays and MRI of the region. Prior to the intervention all the patients had followed a variety of adequate conservative treatment including immobilization, anti-inflammatory therapy, physical therapy, local infiltration with corticoids and xylocain. The results proved unsatisfactory. The surgical technique consisted of triple portal arthhroscopic intervention (anterior, posterior, lateral) and the use of a shaver for the completion of the acromio – plasty. The surgical time was 40 minutes (30 – 55). The post – operative protocol, which included passive and active physiotherapy, was identical for all patients. Results: The required average hospitalization was 36 hours (14 – 48). The average time needed for satisfactory rehabilitation amounted to 27 days (20 – 45). We followed closely our patients for an average of 11 months. (4 – 16). The painful symptoms disappeared thoroughly in 92.7% of our cases (38). Moderate pain persisted in 7.3% (3). Shoulder movements were fully restored in 95.1% (39). We observed no peri-operative or post – operative complications. Conclusions: The arthroscopic airomioplasty is the surgical treatment of choice in the cases of sub-aromial impingement. The method presents no great technical difficulties. The operative time is considered short, and the results in their great majority are excellent. The hospitalization needed is minimal, the rehabilitation is rapid, and the economic cost is not significant. We firmly believe that the arthroscopic acromio – plasty is the treatment of choice in the case of failed conservative treatment

Purpose: Operative wounds are commonly washed with a more or less diluted antiseptic solution to prevent infection or to treated overt infection. Chlorhexidine is widely used. We report the cases of nine patients who developed joint destruction attributed to peroperative irrigation with a chlorhexidine solution. Material and methods: Nine patients (three men and six women) who had undergone surgery in another facility were referred to our unit for unexplained postoperative chondrolysis. The joint localisations were: wrists (n=7) after surgery for a dorsal arthrosynovial cyst (mean age 37 years); elbow (n=1) after surgery for epicondylalgia (age 49 years); shoulder (n=1) after arthroscopy for sub-acromial impingement (age 51 years). The time between surgery and the first consultation in our unit varied from three to nine years (mean five years four months). Persistent stiffness had been noted in the postoperative period with pain at joint mobilisation which worsened progressively. For the patients with chondrolysis of the wrist: the x-rays demonstrated destruction of the radius-first ray joint in one, the medio-carpal joint in four and overall destruction in two. Overall joint destruction was also observed in the elbow and shoulder patients. Search for other causes of joint destruction was negative; infection and inflammatory rheumatoid disease were ruled out. The common feature identified in all patients was joint irrigation with a chlorhexidine solution (Biseptine®). Results: Four of the nine patients underwent surgical treatment: a four-bone arthrodesis with scaphoidectomy was used for the three patients with mediocarpal involvement and a shoulder arthrodesis was performed in one patient. The pathology study demonstrated cartilage defects filled with dense strongly hyalinised acellular tissue. Bacteriological specimens were all negative. Discussion: The chondrolytic effect of chlorhexidine, a member of the biguanide family, was first reported in 1986 with a few cases described with knee involvement. Experimentally, there would be a dose-dependent effect. The mechanism involves a disorganisation of the cell membrane with cartilaginous necrosis and ostocartilaginous resorption. Individual predisposition cannot be ruled out. Conclusion: In light of these observations, it would be advisable to avoid peroperative joint irrigation with chlorhexidine solution

Arthroscopic subacromial decompression for shoulder impingement syndrome is one of the commonest procedures performed by the shoulder surgeon. Although much has been written on this procedure since Ellman published in 1985, very little work has been carried out on the rate of recovery after surgery, despite this being one of the main concerns of the patient. This prospective study describes the early functional results after this procedure and the rate of recovery seen. Sixty-eight patients underwent arthroscopic subacromial decompression for shoulder impingement syndrome between January and November 2000. All patients had suffered pain for at least six months prior to surgery, and all were diagnosed on the basis of clinical findings, radiographic evidence, and a positive response to Neer’s impingement test, i.e. abolition of pain after an injection of local anaesthetic into the subacromial space. All patients were evaluated preoperatively, at three weeks and three months post operatively using the Constant score to obtain an objective assessment of shoulder function. Surgery was carried out via an arthroscopic technique using the Dyonics power shaver with the 4.5 mm Helicut blade (Smith & Nephew). Immediate post operative physiotherapy was allowed, together with the encouragement of activities of daily living. Sixty-eight patients with a mean age of 45 years (range: 30–77 years) underwent surgery over a 10 month period. Male: female ratio was 60:40, and the lateral clavicle was affected in 33 cases, resulting in the need for an acromioclavicular joint resection to be performed arthroscopically at the same sitting. Mean preoperative Constant score was 46.5 (34–67), at three weeks 65.8 (40–86), and at three months 82.4 (50–99). Sixty-five out of 68 patients returned to full activities, including heavy manual work where necessary, by three month review. There was no correlation between the impingement grade, presence of a cuff tear, or acromioclavicular joint involvement, and a significantly poorer outcome. In particular, no patient was made worse by surgery, and at the latest review of the cohort the improvement seen has not deteriorated. Arthroscopic subacromial decompression is a reliable method of improving the functional ability of patients with subacromial impingement syndrome, with a 20 point increase in the Constant score at three weeks post surgery, rising to a 40 point increase at three months. Patients can therefore be counseled that they will make a significant functional improvement in a short time after surgery

The December 2014 Shoulder & Elbow Roundup³⁶⁰ looks at: cuff tears and plexus injury;

corticosteroids and physiotherapy in SAI; diabetes and elbow arthroplasty; distal biceps tendon repairs; shockwave therapy in frozen shoulder; hydrodilation and steroids for adhesive capsulitis; just what do our patients read?; and what happens to that stable radial head fracture?
