The aim of the study was to assess the medium term outcome for complex proximal humeral fractures treated with the long proximal humeral internal locking system (PHILOS) plate fixation. All patients who had long PHILOS plate fixation of proximal humerus fractures with metaphyseal or diaphyseal extension over a three year period at our institution were included in the study. Patients had their case notes and radiographs reviewed. Patients were also contacted to assess functional outcome using the Visual Analogue Scale (VAS) for pain, DASH, Oxford shoulder score (OSS) and Stanmore Percentage of Normal Shoulder Assessment (SPONSA). Out of an initial cohort of 34 patients, 1 died, 2 patients had unrelated illnesses resulting in them being unable to complete the assessment and 6 were lost to follow-up, leaving 25 patients (74%) for review. All patients had proximal humeral fractures with metaphyseal or diaphyseal extension requiring long plate osteosynthesis. One patient had the procedure for non union following initial treatment with an intra medullary nail and the rest were acute injuries. The patients were followed up after a mean of 27 months (range 11–60). The length of plate used varied from 5 to 12 holes for the shaft region. There was 1 wound infection. 3 patients had non unions which required bone grafting and revision internal fixation. At final follow-up, mean pain was 3.6 (95% Confidence Interval 2.5–4.8) with only 4 patients having residual pain greater than 5 on the VAS scale. Mean DASH score was 41.2 (95% CI 32.0–50.4), mean OSS was 29.1 (95% CI 24.3–33.9) and mean SPONSA was 63.9% (95% CI 50.8–77.2) The long PHILOS plate appears to represent a good treatment option for complex proximal humerus fractures with favourable medium term results and few complications.
The aim of the study was to assess the rate of greater tuberosity non union in reverse shoulder arthroplasty performed for proximal humerus fractures and to assess if union is related to type of fracture or the intraoperative reduction of the greater tuberosity. All cases of reverse shoulder arthroplasty for proximal humerus fractures at our institution over a three year period were retrospectively reviewed from casenotes and radiologically and the position of the greater tuberosity was documented at immediate post op, 6 months and 12 months. Any malunion or non union were noted. A total of 27 cases of reverse shoulder arthroplasty for proximal humeral fractures were identified. 4 cases did not have complete follow up xrays and were excluded from analysis. The average age at operation of the cohort of the 23 remaining patients was 79 years (range 70–91). The greater tuberosity was anatomically well positioned intraoperatively in 17 of the 23 cases. At the end of 12 months there were 4 cases of tuberosity non union (17%), all except one occurring in poorly intraoperatively positioned greater tuberosity. 50% (3 out of 6) of greater tuberosities displaced further and remained ununited if the intraoperative position was poor. Only 6% (1 out of 17) greater tuberosities did not unite if the greater tuberosities was reduced anatomically. Intra operatively position of the greater tuberosity was strongly associated with their union (Fischer's exact test p<0.05). Union of greater tuberosity was not statistically associated with fracture pattern (Fischer's exact test p=0.48). Our case series show a low rate of tuberosity malunion after reverse shoulder arthroplasty for proximal humerus fracture. Good positioning and fixation of the greater tuberosity intra operatively is a strong predictor of their uneventful union to shaft.
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%.
