Bone defects are frequently observed in anterior shoulder instability. Over the last decade, knowledge of the association of bone loss with increased failure rates of soft-tissue repair has shifted the surgical management of chronic shoulder instability. On the glenoid side, there is no controversy about the critical glenoid bone loss being 20%. However, poor outcomes have been described even with a subcritical glenoid bone defect as low as 13.5%. On the humeral side, the Hill-Sachs lesion should be evaluated concomitantly with the glenoid defect as the two sides of the same bipolar lesion which interact in the instability process, as described by the glenoid track concept. We advocate adding remplissage to every Bankart repair in patients with a Hill-Sachs lesion, regardless of the glenoid bone loss. When critical or subcritical glenoid bone loss occurs in active patients (> 15%) or bipolar off-track lesions, we should consider anterior glenoid bone reconstructions. The techniques have evolved significantly over the last two decades, moving from open procedures to arthroscopic, and from
Aims. The aim of this study is to report the results of a case series of olecranon fractures and olecranon osteotomies treated with two bicortical screws. Methods. Data was collected retrospectively for all olecranon fractures and osteotomies fixed with two bicortical screws between January 2008 and December 2019 at our institution. The following outcome measures were assessed; re-operation, complications, radiological loss of reduction, and elbow range of flexion-extension. Results. Bicortical screw fixation was used to treat 17 olecranon fractures and ten osteotomies. The mean age of patients being treated for olecranon fracture and osteotomy were 48.6 years and 52.7 years respectively. Overall, 18% of olecranon fractures were classified as Mayo type I, 71% type II, and 12% type III. No cases of fracture or osteotomy required operative re-intervention. There were two cases of loss of fracture reduction which occurred in female patients ≥ 75 years of age with osteoporotic bone. In both cases, active extension and a functional range of movement was maintained and so the loss of reduction was managed non-operatively. For the fracture fixation cohort, at final follow-up mean elbow extension and flexion were -5. °. ± 5. °. and 136. °. ± 7. °. , with a mean arc of motion of 131. °. ± 11. °. . Conclusion. This series has shown that patients regain near full range of elbow flexion-extension and complication rates are low following bicortical
