Radiocapitellar arthroplasty.

J Clin Orthop Trauma 2021 Aug 24;19:237-244. Epub 2021 May 24.

Department of Orthopaedics, Jan Yperman Hospital, Ieper, Belgium.

This article sets out the evidence demonstrating that the clinical need for a prosthetic arthroplasty designed specifically for the radiocapitellar joint has been underestimated. The prevalence of radiocapitellar degenerative change requiring treatment is discussed and the relationship between 'isolated' radiocapitellar joint arthritis and more generalised elbow arthritis is explained. Current literature now supports our view that radiocapitellar joint arthroplasty is not only an effective long-term solution for patients with localised radiocapitellar arthritis but also for those patients with more severe degenerative changes involving the elbow joint irrespective of their cause.

Authors:
Jörn Kircher

Arthrosc Tech 2021 May 18;10(5):e1217-e1222. Epub 2021 Apr 18.

Department of Shoulder and Elbow Surgery, ATOS Klinik Fleetinsel Hamburg, Hamburg; and Department of Orthopedic and Trauma Surgery, Heinrich-Heine-University Düsseldorf, Medical Faculty, University Hospital, Düsseldorf, Germany.

Multidirectional shoulder instability and hyperlaxity can be treated with arthroscopic shoulder stabilization and capsular shift. In these patients, the joint capsule often becomes the weak link in terms of pullout strength and cutting through of the used sutures, which can further be compromised by reduced quality of the capsular tissue. The described delta-loop-stitch combines a loop stitch through the capsule with a 3-point-fixation to the intact labrum thus distributing the load and reducing the risk of failure of the fixation.
