Technical Note: Arthroscopic Resection of Snapping, Interponating Annular Ligament of the Elbow

Abstract

The indication for surgical treatment of lateral snapping elbow syndrome is recurrent joint blockage in combination with pain of the affected elbow joint. Different parts of the lateral synovial capsule sleeve complex, including the annular ligament itself, a hypertrophic synovial fold, or meniscus-like soft tissue interposition can lead to painful entrapment. Surgical treatment options can include an arthroscopic or open procedure. The aim of this technical note is to provide a step-by-step illustration of the authorsʼ preferred arthroscopic approach with a comprehensive review of literature on clinical outcome.

Zusammenfassung

Rezidivierende Gelenkblockaden in Kombination mit Schmerzen und Schnappen im Bereich des lateralen Ellenbogengelenkes können häufig mit einem sogenannten „Snapping annular ligament“ assoziiert werden. Ursächlich hierfür ist eine Interposition des Ligamentum annulare bzw. eine hypertrophierte Plica posterolateralis in das humeroradiale Gelenkkompartiment. Operative Therapieoptionen beinhalten ein arthroskopisches oder offenes Vorgehen. Die nachfolgende Technical note thematisiert das arthroskopische Vorgehen sowie die aktuellste Literatur.
