"Champagne Fracture": A Superior Fracture-Dislocation of the Proximal Humerus: A Case Report.

A 79-year-old right-handed woman presented with an indirect trauma to her left shoulder after a fall down the stairs. X-rays and computed tomography showed a four-part glenohumeral fracture-dislocation with a subcutaneous ectopic location of the humeral head in the retroclavicular space. A reverse total shoulder arthroplasty was performed using a deltopectoral approach with direct superior extraction of the humeral head.

Long-term survival analysis of 191 MAÏA® prostheses for trapeziometacarpal arthritis.

Surgery for trapeziometacarpal osteoarthritis after failure of medical treatment remains controversial. The aim of this study was to determine the long-term results of the MAÏA® trapeziometacarpal prosthesis (Lépine, Genay, France). This was a retrospective clinical and radiographic study of 191 MAÏA® trapeziometacarpal prostheses implanted between 2001 and 2016 from a single centre.

Comparative study of a Y- anatomical and innovative locking plate versus double plate for supracondylar humeral fracture.

Introduction: There is no "gold standard" for the type of plate to be used for distal extra-articular humeral fractures; the most used is plating of each column. The objective was to evaluate the short-term clinical and radiological results of a Y- anatomical and innovative locking plate (YALP).

Hypothesis: The hypothesis is: this anatomical and innovative locking plate will produce satisfactory and reliable results on extra-articular distal humerus fracture superior to double plate fixation.
