The aim of this study was to evaluate prospectively the outcome following arthroscopic Bankart repair using two types of suture anchors, absorbable and non-absorbable. Patients with a diagnosis of recurrent traumatic anterior instability of the shoulder, seen between April 2000 and June 2003 in a single unit, were considered for inclusion in the study. Patients were assessed pre-operatively and post-operatively using a subjective patient related outcome measurement tool (Oxford instability score), a visual analogue scale for pain and instability (VAS Pain and VAS instability) and a quality of life questionnaire (SF-12). The incidence of recurrent instability and the level of sporting ability were recorded. Patients were randomised to undergo surgical repair with either non-absorbable or absorbable anchors. 130 patients were included in the study. 6 patients were lost to follow-up and 124 patients (95%) completed the study. Both types of anchors were highly effective. There were no differences in the rate of recurrence or any of the scores between the two. Four patients in the non-absorbable group and 3 in the absorbable group experienced further episodes of dislocation after a traumatic event. The rate of redislocation in the whole series was therefore, 5.6%. In addition, 4 patients, all of them in the absorbable group (4%) described ongoing symptoms of instability but no true dislocations. 85% of the patients have returned to their previous level of sporting activity. There are no differences in the outcome of Arthroscopic Bankart repair using either absorbable or non-absorbable anchors. Both are highly effective, showing a redislocation rate of 5.6%.
A prospective study was carried out over a period of 4 years. 31 patients with a mean age of 49 years were treated using the clavicular hook plate. The mean follow up was 28.34 months. 23 patients were operated primarily and 8 patients were operated for symptomatic non-union. All the patients achieved clinical and radiological union in a mean 12.71 weeks. According to Constant scoring the mean was 94. According to HSS (Hospital for Special Surgery) scoring 9 patients had excellent, 21 had good. The clinical results of the clavicular hook plate were good leading to good shoulder girdle function.
Scapular instability is a disabling deformity that results in pain and influences the overall upper limb function ; for which scapular stabilization may be necessary.
The technique used for fusion was plate and wires in 6, Rush pin and wires in 2. All of them had bone grafting . At the last follow up the mean DASH score was 37 and the mean constant score was 74.67. All patients had mild or no pain,felt their scapula stable and were satisfied with the outcome. The main post operative complaint was wire breakage and migration that necessitated removal in 3 patients. We conclude that scapulothoracic fusion is a valuable procedure and can restore reasonable shoulder function and relieve pain in patients with scapular instability.
