Miniopen coracohumeral ligament release and manipulation for idiopathic frozen shoulder

摘要

In the management of idiopathic frozen shoulder, manipulation under anaesthesia is known to have serious potential complications including fractures and intra-articular injuries. Arthroscopy is a safer treatment modality but requires special instruments, experience, and involves added cost. The aim of this work was to study the use of miniopen Coracohumeral ligament release and manipulation of the shoulder as a safe and simple method of treating idiopathic frozen shoulder that could be performed as a quick procedure under short duration anaesthesia obtaining a significant improvement of shoulder function while avoiding complications that are feared to occur with the use of manipulation under anaesthesia. Miniopen Coracohumeral ligament release is performed through a 3-cm incision. The Coracohumeral ligament is divided, and then the shoulder is manipulated without undue force. A case series including fifteen patients (19 shoulders) with idiopathic frozen shoulder operated by this technique is described. Miniopen Coracohumeral ligament release and manipulation is a quick procedure that may be performed under short duration anaesthesia obtaining a significant improvement of shoulder function meanwhile avoiding complications that are feared to occur with the use of manipulation under anaesthesia.Keywords: coracohumeral ligament, frozen shoulder, mini-open, safe, simple
