Arthroscopically assisted core decompression of the proximal humerus for avascular necrosis.

Abstract

Abstract Core decompression has been described as an effective treatment for early stage avascular necrosis of the humeral head. This article describes the technique for arthroscopically assisted core decompression of the humeral head using a transtibial anterior cruciate ligament guide. This technique provides an advantage over the open procedure by avoiding soft-tissue stripping or damaging the biceps tendon or ascending branch of the anterior humeral circumflex artery, as well as providing accurate and safe placement of the core biopsy tract and the ability to address other intra-articular pathology.
