Indikationen und Operationstechniken für kombinierte mediale und laterale Eingriffe bei schwerer extrinsischer Ellenbogensteife

Abstract

Severe extrinsic elbow contracture can be treated effectively using elbow arthrolysis to obtain satisfactory results. Preoperative planing is of prime importance to evaluate joint involvement and to decide how to approach the capsule from the lateral or medial aspect of the elbow. Most of the time because of the extensive involvement of the periarticular tissue, a combined approach is usually preferred. It is a step-by-step procedure that must be adapted to the progressive gain of motion. The ulnar nerve must be identified systematically and often anteriorly transposed. Maximum gain of motion must be obtained at surgery because loss of elbow motion after surgery is common. Postoperative management must be closely followed static splint being preferable to active physiotherapy. Results of surgical arthrolysis for extrinsic stiffness is often satisfactory with an absolute gain in the flexion-extension arc between 30 and 60°.
