Double plating - surgical technique and good clinical results in complex and highly unstable proximal humeral fractures.

Injury 2021 Jun 5. Epub 2021 Jun 5.

Department of Orthopedics and Traumatology, Diakovere Friederikenstift, Humboldtstraße 5, Hanover 30169, Germany.

Introduction: A stable fixation of highly unstable proximal humerus fractures remains challenging and complication rates, especially secondary varus dislocation, remains high. Different techniques of double plate osteosynthesis have been suggested for the treatment of complex proximal humeral fractures as they are well established for other fractures. The aim of this study was to evaluate an operative technique using an angular stable lateral plate supported by a one-third tubular plate positioned anteriorly at the lesser tuberosity for unstable proximal humeral fractures.

Variability of Glenoid Labral Tear Patterns: A Study of 280 Sequential Surgical Cases.

J Shoulder Elbow Surg 2021 May 18. Epub 2021 May 18.

Peachtree Orthopaedics, Atlanta, GA, USA. Electronic address:

Background: Glenoid labrum tears are a common cause of shoulder pain and instability and tear patterns have historically been ascribed into categorical descriptions such as anterior, posterior, and superior labral tears (SLAP) with multiple sub-types. Although often quoted as representing no more than 10% of instabilities, posterior shoulder instability may be more common than previously recognized. The purpose of this study was to review observed labral tear patterns and compare incidence and morphologies to historical descriptions. Read More
