Complications and revisions in metal-backed anatomic total shoulder arthroplasty: a comparative study of revision rates between stemless and stemmed humeral components.

Background: The primary objective of this study was to evaluate and compare the incidence of complications and revision surgeries between in 2 of convertible metal-back glenoid systems in total shoulder arthroplasty (aTSA) groups over a follow-up period of up to 5 years.

Methods: A retrospective analysis included 69 shoulders from 65 patients with primary aTSA. Patients were divided into group 1 (n = 31), receiving convertible cementless stemmed aTSA (Lima SMR) and group 2 (n = 38), receiving humeral head replacement aTSA (Arthrex, Eclipse) both with metal-back glenoid components.

Age-Independent Clinical Outcome in Proximal Humeral Fractures: 2-Year Results Using the Example of a Precontoured Locking Plate.

Introduction: The optimal treatment strategy for the proximal humeral fracture (PHF) remains controversial. The debate is centered around the correct treatment strategy in the elderly patient population. The present study investigated whether age predicts the functional outcome of locking plate osteosynthesis for this fracture entity.
