A new nail with a locking blade for complex proximal humeral fractures
INTRODUCTION: The objective of this study was to assess the clinical outcome of displaced proximal humerus fracture treated with a new locking blade nail. MATERIALS AND METHODS: This prospective study included a series of 92 patients with acute fracture of the proximal humerus treated in one hospital level I trauma centre with locking blade nail between December 2010 and December 2013. According to the Neer classification, all fractures were two- to four-part fractures. Age adopted Constant score, DASH and visual analogue scores were used as outcome measures. RESULTS: A total of 92 patients were enrolled in the study. However, 29 patients were excluded due to loss to follow-up and death. Ultimately, 63 patients were available for final follow-up and data analysis. The mean duration of follow-up was 22 months (range 16–48 months). On average at 1 year, all fractures had united. The mean weighted Constant score was 84.2 % and the median disabilities of the arm, shoulder and hand (DASH) score was 26, the range of elevation was 115 and range of abduction was 97. The head shaft angle was 130, and pain visual analogue was 1.6. We found that 5 of the 63 patients (8 %) demonstrated complications. Two patients (3 %) displayed secondary displacement and require device removal. Two patients (3 %) had impingement due to prominent metal work, and one patient had a superficial wound infection which was treated with a course of antibiotics. CONCLUSION: Our study shows excellent results with new locking blade nail for displaced proximal humerus fractures. We think the locking blade nail offers stiff triangular fixation of the head fragment and support of the medial calcar region to prevent secondary varus collapse. LEVEL OF EVIDENCE: III

Shoulder hemiarthroplasty for fractures of the proximal humerus
Proximal humeral fractures were managed with primary hemiarthroplasty in 57 patients, 53 women (93%) and 4 men (7%) aged 51–87 years (mean 72.2). The mean follow-up period was 52 months (range 12–98), and the mean Constant score was 59.2 (range 38–76). Patients were very satisfied (n = 19); satisfied (n = 32) or dissatisfied with the outcome (n = 5). One patient required early revision surgery. Surgical treatment of three- and four-part fractures of the proximal humerus with hemiarthroplasty is a safe and effective approach, the outcome of which appears to be related to the quality of the anatomical reconstruction of the tuberosities
Does fixed-angle plate osteosynthesis solve the problems of a fractured proximal humerus?: A prospective series of 87 patients
Background and purpose There is considerable controversy about the treatment of complex, displaced proximal humeral fractures. Various types of head-preserving osteosynthesis have been suggested. This prospective case series was designed to evaluate the perioperative and early postoperative complications associated with fixed-angle implants and to record outcome after bone healing

Open MR imaging of the unstable shoulder in the apprehension test position: description and evaluation of an alternative MR examination position
The aim of this study was to describe and evaluate an alternative MR assessment procedure for analysis of unstable shoulders. Twelve patients with unilateral recurrent anterior shoulder dislocation had both shoulders examined. Magnetic resonance imaging was performed with an open-MR system in the apprehension position with the shoulder in 90 ° of abduction and maximum tolerable external rotation. Contrast enhancement was achieved with intravenous gadolinium. Correlations were made to the findings at operation. In 10 of 12 unstable shoulders the inferior glenohumeral ligament labral complex (IGHLLC) was detached from the glenoid as seen on MR and later verified during surgery. In one shoulder MR was unable to show a capsulolabral detachment that was verified at surgery, whereas in one shoulder both MR and surgical assessment revealed no soft tissue detachment (accuracy 92 %). A Hill-Sachs lesion was visualized and verified in all unstable shoulders, whereas the stable controls revealed normal IGHLLC and no Hill-Sachs lesion. Open-MRI evaluation of the shoulder in the apprehension test position may become a useful tool for the evaluation of anterior shoulder instability
