Open reduction and internal fixation versus minimally invasive plate osteosynthesis of unstable proximal humerus fractures treated with locking plate and intramedullary allograft: A retrospective study.

Background: This retrospective clinical study aims to compare the functional and radiological outcomes after open reduction and internal fixation versus minimally invasive plate osteosynthesis of unstable proximal humerus fractures treated with both locking plate and intramedullary graft.

Methods: Forty-seven patients with proximal humerus fractures were treated with either open reduction and internal fixation (25 cases) or minimally invasive plate osteosynthesis (22 cases) and evaluated retrospectively with a minimum follow-up of 12 months. Thirty-one fresh-frozen fibulae and 16 lyophilized tibia allografts were used for augmentation.

Volar versus combined dorsal and volar plate fixation of complex intraarticular distal radius fractures with small dorsoulnar fragment - a biomechanical study.

Complex intraarticular distal radius fractures (DRFs), commonly managed with volar locking plates, are challenging. Combined volar and dorsal plating is frequently applied for treatment, however, biomechanical investigations are scant. The aim of this biomechanical study was to investigate volar plating versus double plating in DRFs with different degrees of lunate facet comminution.

Two reconstruction plates provide superior stability of displaced midshaft clavicle fractures in comparison to single plating - A biomechanical study.

Background: Displaced midshaft fractures are the most common surgically treated clavicle fractures. However, they are associated with high complication rates following plating due to fixation failure in terms of plate breakage, screw breakage and/or screw loosening. The aim of this study was to compare the biomechanical competence of three different plating techniques for fixation of displaced midshaft clavicle fractures.

Does Supplemental Intramedullary Grafting Increase Stability of Plated Proximal Humerus Fractures?

Objectives: To investigate the biomechanical competence of locked plating augmented with supplemental intramedullary graft in comparison to conventional locked plate fixation in proximal humerus fractures (PHF).

Methods: Complex four-part PHFs were set in 30 artificial humeri assigned to 3 study groups (n = 10 in each group). Group 1 was characterized by loss of medial support, group 2 by simulated severe cancellous bone damage due to osteoporosis, and group 3 by combination of the 2 features.

Complications after interlocking intramedullary nailing of humeral shaft fractures.

Introduction: IM nails have gained popularity for stabilization of humeral shaft fractures (HSF). The initial enthusiasm was tempered by a number of specific complications and thus indications need to be re-evaluated.

Patients And Methods: This retrospective study includes 111 patients with HSF subjected to a treatment protocol of IM fixation with first and second generation of humeral nails.
