BACKGROUND Proximal humeral fractures are common lesions of the elderly, but there are no established treatment guidelines. A surgical treatment for comminuted and displaced fractures of the proximal humerus was developed and is still evolving. The aim of this study was to perform a quantitative review to evaluate the risk of avascular necrosis (AVN) in patients with proximal humeral fractures ...

BACKGROUND Humeral head fractures and their postoperative outcome remain a challenging problem in surgical daily routine. Predictive factors for loss of fixation are rare. OBJECTIVE Determination of predictive factors for the failure of osteosynthesis with the loss of fixation or migration of screws in humeral head fractures. METHOD From 1995 to 2011, 408 patients with proximal humeral frac...

BACKGROUND Proximal humeral fractures in elderly patients present with severe comminution and osteoporotic bone quality. Reverse shoulder arthroplasty has lately been proven beneficial in treating patients with complex proximal humeral fractures. The above technique is recommended and has better results in elderly than in younger individuals. METHODS We performed a literature search in the da...

BACKGROUND Complex acute proximal humeral fractures may require prosthetic replacement of the proximal humerus. Reverse shoulder arthroplasty (RSA) has been suggested as an alternative to hemiarthroplasty in the management of such fractures. This study compared the functional outcomes of RSA with hemiarthroplasty in patients with acute proximal humeral fractures. MATERIALS AND METHODS All pat...

Proximal humeral fractures are common and most challenging, due to the complexity of the glenohumeral joint, especially in the geriatric population with impacted fractures, that the development of implants continues because currently the problems with their fixation are not solved. Pre-, intra-, and postoperative assessments are crucial in management of those patients. Finite element analysis, ...

Displaced three- and four-part proximal humerus fractures are among the most challenging shoulder conditions to manage. Because of the risk of symptomatic malunion, nonunion, and humeral head osteonecrosis, surgical management is preferred. Locking plate technology has provided an alternative to hemiarthroplasty for certain three- and four-part fracture patterns, even in the setting of osteopen...

Distal humeral fractures in adults are relatively uncommon injuries that require operative intervention in the majority of cases. Dual plate fixation, with placement of a separate strong plate on each column and orientation of the plates either at 90° or 180° to each other, is indicated for all adult fractures involving both columns of the distal part of the humerus. Acute total elbow arthropla...

Introduction: Approximately 15 to 20 percent of all proximal humeral fractures are displaced and require operative treatment [1]. Reduced bone quality of the humeral head complicates internal fixation and may result in implant loosening, fracture re-displacement and poor functional outcome for the patient [2, 3]. Little is known about the effect of bone mineral density (BMD) on internal fixatio...

BACKGROUND The purpose of this study was to evaluate the biomechanical advantages of medial support screws (MSSs) in the locking proximal humeral plate for treating proximal humerus fractures. METHODS Thirty synthetic left humeri were randomly divided into 3 subgroups to establish two-part surgical neck fracture models of proximal humerus. All fractures were fixed with a locking proximal hume...
