Weber Ankle Fracture Classification System Yields Greatest Interobserver and Intraobserver Reliability Over AO/OTA and Lauge-Hansen Classification Systems Under Time Constraints in an Asian Population.

No previous studies have evaluated the intra- and interobserver reliability between the Weber, Lauge-Hansen and AO Foundation/Orthopaedic Trauma Association (AO/OTA) classification systems under time constraints. This study compares the interobserver and intraobserver reliability of the aforementioned classification systems under simulated time constraints. Anteroposterior and lateral radiographs of ankle malleolar fractures from 80 consecutive patients from 2015 to 2016 were classified by 2 independent observers according to Weber, Lauge-Hansen and AO/OTA.

Outcomes of Reverse Total Shoulder Arthroplasties Performed for Proximal Humeral Fractures Versus Elective Etiologies.

Background: Reverse Total Shoulder Arthroplasty is commonly performed for elective indications, such as cuff tear arthropathies, salvage arthropathies and tumours with excellent outcomes. However, its use in treating acute conditions such as 3- and 4-part proximal humeral fractures in the elderly has been more controversial. The aim of our study is to directly compare the short-term intra-operative and post-operative outcomes of RTSA for traumatic proximal humeral fractures as compared to elective shoulder arthroplasty.
