Rotator cuff tears are common in middle-aged and elderly patients. Despite advances in the surgical repair of rotator cuff tears, the rates of recurrent tear remain high. This may be due to the complexity of the tendons of the rotator cuff, which contributes to an inherently hostile healing environment. During the past 20 years, there has been an increased interest in the use of biologics to complement the healing environment in the shoulder, in order to improve rotator cuff healing and reduce the rate of recurrent tears. The aim of this review is to provide a summary of the current evidence for the use of forms of biological augmentation when repairing rotator cuff tears. Cite this article:

Indocyanine green (ICG) fluorescence angiography is an emerging technique that can provide detailed anatomical information during surgery. The purpose of this study is to determine whether ICG fluorescence angiography can be used to evaluate the blood flow of the rotator cuff tendon in the clinical setting. Twenty-six patients were evaluated from October 2016 to December 2017. The participants were categorized into three groups based on their diagnoses: the rotator cuff tear group; normal rotator cuff group; and adhesive capsulitis group. After establishing a posterior standard viewing portal, intravenous administration of ICG at 0.2 mg/kg body weight was performed, and fluorescence images were recorded. The time from injection of the drug to the beginning of enhancement of the observed area was measured. The hypovascular area in the rotator cuff was evaluated, and the ratio of the hypovascular area to the anterolateral area of the rotator cuff tendon was calculated (hypovascular area ratio).Objectives
Methods
Total shoulder arthroplasty (TSA) and reverse shoulder arthroplasty (RSA) are excellent surgical options for individuals with shoulder arthritis, providing good to excellent results in the vast majority of patients. Complications are rare, but can be devastating for both the patient and surgeon. An uncommon, but extremely problematic complication following shoulder arthroplasty is shoulder stiffness. While substantial literature discussing post-arthroplasty stiffness is available for other joints such as the hip, knee, and elbow, there is a paucity of research available discussing this complication in the shoulder. As noted in multiple reviews, diminished range of motion following TSA or RSA may be due to a number of factors, including pre-operative diagnosis of proximal humerus fracture, inadequate post-operative rehabilitation, implant-related factors such as malpositioning and/or inappropriate-sized implants, and heterotopic ossification. Often, pathology leading to post-arthroplasty stiffness involves scarring of the long head of the biceps tendon, rotator
Summary. Data of 663 patients with three different pathologies were examined. We found that using patients with significant symptoms and functional difficulty in the opposite shoulder will not bias the results of observational studies if outcomes are based on routine disability measures such as ASES or Constant-Murley scores. Introduction. Recently, using patients with bilateral limb problems as independent cases has raised concerns in orthopaedic research due to violating the assumption of independence. If observations are too similar in characteristics, they become highly correlated which leads to lowering the variance and biasing the results. Type of pathology (impingement, cuff tear, osteoarthritis) and aging are expected to affect the incidence of bilateral shoulder complaints and should be considered when examining potential bias in this area. In addition, the impact of dominant side pathology has not been investigated primarily in patients with shoulder problems. The objectives of this study were: 1) to examine the incidence of bilateral shoulder complaints and pathology on the dominant side in patients with impingement syndrome, rotator cuff tear and osteoarthritis of the glenohumeral joint, 2) to explore the role of sex and age in developing bilateral shoulder complaints, and 3) to examine the impact of bilaterality and hand dominance on pre and one year post-operative disability. Patients and Methods. This study involved review of data of patients with a diagnosis of impingement syndrome, rotator cuff tears and osteoarthritis (OA) of the gleno-humeral joint who had undergone surgery and had returned for their one year follow-up. Two outcome measures were used; the American Shoulder & Elbow Surgeons (ASES) and the Constant Murley score (CMS). Results. Data of 663 patients (317 females; 269 impingement syndrome, 290 rotator cuff tear, 104 osteoarthritis) were included in the analysis. There was a difference in the incidence of bilateral symptoms in patients with different pathologies: osteoarthritis 46%, impingement 26%, and rotator cuff tears 23% (p<0.0001). The incidence of dominant side involvement was 70%, 68% and 50% in patients with rotator
Aim. To review the natural history of upper limb osteochondromas and assess their functional effect. Materials. We performed a retrospective casenote review of a consecutive patient cohort presenting between 1997–2012 with upper limb osteochondromas. Indications for surgical intervention were noted and considered to be cosmetic, functional (including pain relief) and ‘prophylactic’ in terms of deformity prevention. All patients were invited to complete questionnaires for the PODCI, DASH, OSS and MHS scores. Results. We identified 102 patients (62 male: 40 female; mean age = 13.3 years; range 3–31 years). 84 patients had multiple exostoses whilst 18 had a solitary lesion. 52 patients had shoulder girdle involvement (scapula, clavicle and proximal humerus), 51 forearm (Masada I (n=31) Masada II (n=9) Masada III (n=11)), and 38 hand involvement. 46/102 patients had concurrent lower limb lesions. 56 operative procedures were performed primarily for functional benefit. Shoulder girdle procedures (n=21) improved pressure related pain, scapular pseudowinging/dyskinesia and
A total of 159 patients (84 women and 75 men,
mean age of 53 (20 to 87)) with subacromial impingement were randomised
to treatment with subacromial injections using lidocaine with one
of hyaluronic acid (51 patients), corticosteroid (53 patients) or
placebo (55 patients). Patients were followed up for 26 weeks. The
primary outcome was pain on a visual analogue score (VAS), and secondary
outcomes included the Constant Murley score, shoulder pain score,
functional mobility score, shoulder disability questionnaire and
pain-specific disability score. The different outcome measures showed
similar results. After three, six and 12 weeks corticosteroid injections
were superior to hyaluronic acid injections and only at six weeks
significantly better than placebo injections. The mean short-term
reduction in pain on the VAS score at 12 weeks was 7% ( We were not able to show a convincing benefit from hyaluronic
acid injections compared with corticosteroid or placebo injections.
Corticosteroid injections produced a significant reduction in pain
in the short term (three to 12 weeks), but in the long term the
placebo injection produced the best results.
We treated 47 patients with a mean age of 57 years (22 to 88) who had a proximal humeral fracture in which there was a severe varus deformity, using a standard operative protocol of anatomical reduction, fixation with a locking plate and supplementation by structural allografts in unstable fractures. The functional and radiological outcomes were reviewed. At two years after operation the median Constant score was 86 points and the median Disabilities of the Arm, Shoulder and Hand score 17 points. Seven of the patients underwent further surgery, two for failure of fixation, three for dysfunction of the rotator cuff, and two for shoulder stiffness. The two cases of failure of fixation were attributable to violation of the operative protocol. In the 46 patients who retained their humeral head, all the fractures healed within the first year, with no sign of collapse or narrowing of the joint space. Longer follow-up will be required to confirm whether these initially satisfactory results are maintained.
In a prospective randomised study we compared the results of arthroscopic subacromial bursectomy alone with debridement of the subacromial bursa followed by acromioplasty. A total of 57 patients with a mean age of 47 years (31 to 60) suffering from primary subacromial impingement without a rupture of the rotator cuff who had failed previous conservative treatment were entered into the trial. The type of acromion was classified according to Bigliani. Patients were assessed at follow-up using the Constant score, the simple shoulder test and visual analogue scores for pain and functional impairment. One patient was lost to follow-up. At a mean follow-up of 2.5 years (1 to 5) both bursectomy and acromioplasty gave good clinical results. No statistically significant differences were found between the two treatments. The type of acromion and severity of symptoms had a greater influence on the clinical outcome than the type of treatment. As a result, we believe that primary subacromial impingement syndrome is largely an intrinsic degenerative condition rather than an extrinsic mechanical disorder.
We have examined the accuracy of 143 consecutive ultrasound scans of patients who subsequently underwent shoulder arthroscopy for rotator-cuff disease. All the scans and subsequent surgery were performed by an orthopaedic surgeon using a portable ultrasound scanner in a one-stop clinic. There were 78 full thickness tears which we confirmed by surgery or MRI. Three moderate-size tears were assessed as partial-thickness at ultrasound scan (false negative) giving a sensitivity of 96.2%. One partially torn and two intact cuffs were over-diagnosed as small full-thickness tears by ultrasound scan (false positive) giving a specificity of 95.4%. This gave a positive predictive value of 96.2% and a negative predictive value of 95.4%. Estimation of tear size was more accurate for large and massive tears at 96.5% than for moderate (88.8%) and small tears (91.6%). These results are equivalent to those obtained by several studies undertaken by experienced radiologists. We conclude that ultrasound imaging of the shoulder performed by a sufficiently-trained orthopaedic surgeon is a reliable time-saving practice to identify rotator-cuff integrity.

Two surgeons performed arthroscopic subacromial decompression (ASD) on 302 shoulders between January 1995 and January 1999. The mean age of patients was 49.6 years (28 to 81). The mean follow-up period was 36 months (4 to 62). Evaluated using the modified UCLA scoring system, 91% of patients had a good to excellent result at short-term follow-up. However, patients reviewed for two years or longer showed a 98% successful outcome. The commonest delay in improvement was stiffness, with six patients requiring surgical intervention. Early mobilisation with posterior capsular stretching is recommended. Careful clinical assessment of patients with chronic rotator
Painful conditions of the acromioclavicular (AC) joint are common in South Africa, particularly among sportsmen. These conditions are often treated by open excision of the distal end of the clavicle, but an arthroscopic procedure offers many advantages. From February 1994 to February 2000, we performed 138 procedures. The mean age of patients ({71% men and 29% women) was 29 years (19 to 53). In cases of rotator
From January 1995 to January 1999, the author performed arthroscopic subacromial decompression (ASD) on 220 patients. The mean age of patients was 47.4 years (28 to 72). The follow-up period ranged from 4 to 60 months. The modified UCLA scoring system was used to evaluate patients at four months and again at 24 to 60 months. At short-term follow-up, 91% of patients achieved good to excellent results. However, patients reviewed for two years or longer showed a 98% successful outcome. Stiffness was commonly the last thing to improve, and three patients required surgical intervention. Early mobilisation with posterior capsular stretching is recommended.
