Background. Several orthopaedic studies have found significant correlation between pre-operative psychological status and post-operative outcomes. The majority of research has focused on patients requiring lower limb and spine surgery. Few studies have investigated the effect of psychological status on the outcome of upper limb operations. We prospectively investigated the association between pre-operative psychological status and early postoperative shoulder pain and function in patients requiring arthroscopic subacromial decompression (ASAD) for impingement syndrome. Methods. A consecutive series of patients in 2009/10 completed questionnaires 2 weeks pre-operatively and 3 and 6 weeks post-operatively that assessed psychological state, shoulder function and pain. The hospital anxiety and depression scale, the Oxford shoulder score and a pain visual analogue scale assessed psychological status, shoulder function and shoulder pain, respectively. Data was analysed using non-parametric statistical methods. Results. Thirty-one patients participated (21 women; 10 men; mean age 54.6 years; age range 21–89 years). Preoperative anxiety was significantly associated with pre-operative shoulder pain (P < 0.05). Pre-operative psychological status did not correlate with post-operative shoulder pain or function. Greater pre-operative anxiety and depression were significantly associated with post-operative psychological distress (P < 0.05). Overall shoulder pain, function and psychological state improved significantly during the study (P < 0.05) regardless of pre-operative psychological status. Conclusion. Despite pre-operative associations between anxiety and shoulder pain, there were no associations between pre-operative psychological status and post-operative outcomes. Our results from a total of 31 patients suggest there is no justification for routinely assessing psychological status in patients with ‘uncomplicated’ impingement syndromes that require ASAD. The majority of patients benefit from ASAD both physically and psychologically regardless of psychological state. Therefore abnormal pre-operative psychological status should not be a justifiable reason for delaying or denying this effective operation

Introduction

Health Economists in Denmark have recently reported low and delayed return to work for patients treated for Sub-Acromial Impingement syndrome (SAIS) by Arthroscopic Sub-Acromial Decompression (ASAD). Surgeons however are reporting that patients achieve good pain relief and a high standard of activities of daily living (ADL) after surgery.

Purpose of the study:. Improved technology, increasing experience and techniques warrant an analysis of cost effective ways of medical management in general and shoulder decompression specifically. The question raised was whether a less invasive technique is necessarily the most cost effective way or merely the surgeons' preferred technique. This is a retrospective study of patients at Tertiary Academic Institution who underwent an open or arthroscopic shoulder decompression in the past 3 years. The aim of the study is to do a cost analysis of shoulder surgery as private health care (medical aid) is demanding more cost effective procedures and we have limited funds in the Government setting. Methods:. We focused on the following: the surgeon; the procedure; operating time; inpatient time; intraoperative block; physiotherapy costs, time off work and the cost of instrumentation used. Patients had to comply with specific inclusion and exclusion criteria. Inclusion: All patients that had shoulder decompression surgery in the past three years by a qualified orthopaedic surgeon; Exclusion: sepsis, tumours, rotator cuff tears, conversion of an arthroscopic procedure to an open procedure intraoperatively, inadequate notes, multiple surgical procedure under the same anaesthetic (e.g. scope with a trapezium excision). Results:. We evaluated 260 patients. Only 147 complied with the inclusion and exclusion criteria, of which 54 were open decompressions and 73 were arthroscopic decompressions. Arthroscopic surgery was significantly more expensive than open surgery (p<0.0001). Conclusion:. With a 95% confidence level, we concluded that the total cost of an arthroscopic decompression can be between 257.5% and 285.0% higher than that of an open decompression. The outcome of this study has proven that we need to take the cost of every procedure into consideration as our patients can benefit more by the redistribution of funds for other possible procedures. Level of evidence:. Level III

Introduction. The purpose of this study was to assess the rate of revision subacromial decompression and identify different pathologies. Materials/Methods. We analysed the patients who underwent Revision Arthroscopic Subacromial decompression from our prospective database of shoulder patients. Between April 2003 and Dec 2010, 797 patients underwent arthroscopic subacromial decompression. Patients who underwent any other procedure i.e. biceps tenotomy, capsular release, cuff repair were excluded from the study. Of these, 37 underwent a revision subacromial decompression (Revision rate 4.6%). The indication for revision procedure was persistent pain or restricted movements not responding to physiotherapy and injections. Results. We found that 1) Patients having cuff pathology i.e. partial tear or degenerate cuff were more likely to need a revision procedure (11/37 and 92/797, p = 0.001). 2) The rate of ACJ excision done for residual pain after primary subacromial decompression was similar to the rate of ACJ excision at the time of the primary procedure (7/37 vs. 100/797, p= 0.5). 3) Presence of Calcific deposits did not have any influence on the risk of having a revision procedure (2/37 and 12/797, p= 0.1). 4) Patients found to have synovitis in the primary procedure were more likely to need revision procedure (10/37 and 81/797, p = 0.001). 5) Presence of biceps tendonitis did not significantly affect the risk of having a revision procedure after arthroscopic subacromial decompression (3 /37 and 21 /797, p = 0.5). Conclusion. Our revision rate is similar to those published in literature. In our failed cases there was a trend for patients to have an associated partial rotator cuff tear and synovitis

Introduction. Whiplash injury following rear shunt Road traffic accident (RTA) has been associated with impingement syndrome of shoulder. However, the results of arthroscopic subacromial decompression (ASAD) for this group of patients have never been compared to the non accident group. In our study we aim to compare the results of ASAD in these patients to a group who did not sustain whiplash injury. Materials/Methods. Thirteen patients with impingement syndrome following rear shunt RTA were followed up (2004–09). After failed conservative management for at least 6 months ASAD was performed. This group was compared with a control group (not involved in an RTA) of 13 consecutive patients (age and sex matched). All patients were assessed with Oxford shoulder score preoperatively and twice post operatively (within 3 months and at one year). Results. In the RTA group all 13 patients showed improvement in their oxford score over one year. While the improvement was only Marginal (p= 0.08) at three months it was better at the end of a year (p=0.04). Comparatively in the cohort without the whiplash injury the improvement was more marked in the first three months (p=0.05) with significant improvement at the end of the year (p=0.03). The overall improvement in Oxford score was more in the cohort of patients who were not involved in a RTA as opposed to the RTA group (p= 0.05). Conclusion. The results of the study show that even though there was an improvement in shoulder scores after an arthroscopic subacromial decompression it was much slower and overall results were inferior in the RTA group as opposed to the controls and hence prognosis should be guarded when offering ASAD for patients with whiplash injury

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. Methods. Patients attending a designated shoulder clinic and diagnosed by an experienced shoulder surgeon as having a SAIS between January 2009 and December 2011 were considered for inclusion in the study. 67 of 86 patients screened completed the study (3 did not meet inclusion criteria; 9 declined to participate; 3 lost to follow-up; 4 developed frozen shoulder syndrome). Each patient had a pre-injection Oxford Shoulder Score (OSS) and was given one subacromial injection of 10ml 0.25% levobupivacaine(Chirocaine) + 40 mg triamcinolone(Kenalog) through the posterior route. Radiograph imaging was also assessed. Follow-up was carried out at 6 to 12 weeks post injection when OSS was repeated. A 6 month follow-up assessment to assess if the patient's improvement in functionality and absence of symptoms indicated that a subacromial decompression operation was not necessary. The percentage of patients showing improvement in OSS was calculated and the difference in OSS pre- and post-injection assessed using a Wilcoxon Signed Rank test. Results. The median OSS pre-injection was 29 (range 2–43) and post-injection was 40 (range 2–48) (p=< 0.001; z=−6.0; r=−0.5). 45/69 (71%) of patients benefited significantly from subacromial injection at 6 to 12 weeks post-injection. However only 28/53 (53%) benefited significantly from injection by 6 months post-injection. These results support the continued use of sub-acromial corticosteroid injections in the treatment of SAIS. 31% of these patients were subsequently treated with an arthroscopic subacromial decompression operation. Previous injection history had no impact on the results. Conclusions. We recommend that all patients with SAIS should be offered at least one subacromial injection before being considered for an arthroscopic subacromial decompression operation

Introduction. Adhesive capsulitis is a common condition causing painful limitation of shoulder movements. Hydrodistension is one of the techniques, is well recognised and has shown good outcomes. However, the results of hydro distension release in secondary adhesive capsulitis are not clear. Patients and Methods. This is a retrospective study on patients undergoing hydro distension release. Patients who had any surgical intervention were classed as secondary whilst the rest were included in the primary group. The hydro distension is a standard technique where in the senior author locates the gleno humeral joint using radio opaque dye, followed by injection of 20 mls 0.5% L-bupivacaine and 80 mg of Triamcinolone, this is followed by use of 60 mls saline to perform the hydro distension. Results. We included 86 shoulders in 80 patients who underwent the procedure. There were 46 females and 34 males, with average age of 51.07 years (range 35 – 75). Left side was involved in 42 shoulders and right in 44. 25 patients showed associated risk factors of which 17 patients had diabetes, 12 had hypercholesterolemia and 5 had underactive thyroid. 65 of the shoulders were in the primary group whilst 21 in the secondary group. In the secondary group the procedures included 8 arthroscopic subacromial decompression with ACJ excision, 7 had rotator cuff repairs, 4 had biceps labral procedure and 2 ORIF clavicle. 3/21 patients required further intervention in secondary group, whilst 10/65 in the primary group required further intervention. Patients who have history of inflammatory arthritides were found to have higher incidence of revision surgery and poorer outcomes. 85% patients in both groups had improvement in their function and range of movements and were happy with the outcome. Conclusion. Hydrodistension provides safe and predictive results in both primary and secondary adhesive capsulitis and should be considered as an option before any invasive procedure

The incidence of frozen shoulder (FS) as a complication of simple arthroscopic shoulder surgery has yet to be defined. A single-surgeon case series of patients undergoing arthroscopic subacromial decompression (ASD) or ASD with arthroscopic acromioclavicular joint (ACJ) excision was analysed to establish FS rate, this cohort was then compared to a matched group of primary FS patients. Retrospective analysis of 200 consecutive cases was undertaken. All procedures listed, performed and reviewed by the senior author. 96 underwent ASD and 104 underwent ASD and ACJ excision. 6-months follow-up minimum. Incidence of frozen shoulder was 5.21% (ASD) and 5.71% (ASD+ACJ excision). Mean age was 52.3 years (95% CI: 47.4 to 57.2) of the patients that developed FS, compared to 57.2 years (95% CI: 55.2 to 59.2) in the patients who did not and 52 years (95% CI: 50.7 to 53.3) in the primary FS cohort (n=136). 9.1% of post-operative FS were diabetic compared to 17.1% of primary FS. 63.6% were female in the post-operative FS group, 47.1% in the primary FS group. Our results suggest that the risk of FS following simple arthroscopic procedures is 5%, with no increased risk if the ACJ is also excised. This cohort has the same average age as a primary FS. There is a trend toward female sex and diabetes does not increase the risk

Aims. To determine whether a correlation exists between the clinical symptoms and signs of impingement, and the severity of the lesions seen at bursoscopy. Methods. Fifty-five consecutive patients who underwent arthroscopic subacromial decompression were analysed. Pre-operatively patients completed an assessment form consisting of visual analogue pain score, and shoulder satisfaction. The degree of clinical impingement was also recorded. At arthroscopy impingement was classified according to the Copeland-Levy classification. Clinical assessment and scoring was performed at 6 months post-operatively. Linear regression coefficients were calculated to determine if the degree of impingement at arthroscopy correlated with pre-operative pain, satisfaction and clinical signs of impingement. Results. Pre-op pain levels, shoulder satisfaction and the degree of clinical impingement did not correlate with severity of the lesions of the acromion and cuff. (Average Correlation co-efficient r2 = 0.018). There was no correlation between the improvement in the shoulders post-operatively and the severity of lesions (r2 = 0.008). Conclusion. There is no significant correlation between pain, clinical signs, or satisfaction and the severity of lesions seen at arthroscopy

Aim. The present study aimed to assess the accuracy of preoperative departmental ultrasound scans in identifying rotator cuff tears at our institution. Methods. Preoperative ultrasound scan reports were obtained from 64 consecutive patients who subsequently underwent arthroscopic subacromial decompression and/or rotator cuff repair. Data was collected retrospectively using our 2010 database. The ultrasound reports were compared with the arthroscopic findings. The presence or absence of partial and full thickness rotator cuff tears was recorded. Results. Ultrasound correctly identified 30/43 (70%) of all tears, 18/30 (60%) of full thickness tears but only 1/13 (8%) of partial tears seen at arthroscopy. Of the remaining 12 partial tears seen at surgery, 6 were misdiagnosed as full thickness tears on ultrasound and 6 were not picked up at all. Five partial thickness tears were repaired and the rest were debrided. If both full and partial thickness tears are counted as true positives, ultrasound had a sensitivity of 70%, a specificity of 67%, a positive predictive value of 81%, a negative predictive value of 51% and an overall accuracy of 69%. If only partial tears are counted as true positives sensitivity decreases to 8% and positive predictive value to 10%. Conclusion. In this series a preoperative departmental ultrasound scan identified 70% of the actual rotator cuff tears present at arthroscopy. However ultrasound was not accurate in identifying partial thickness tears or distinguishing them from full thickness defects. Due to this relatively low sensitivity, we question the usefulness of routine preoperative departmental ultrasound scans in the evaluation of suspected cuff tears
