Symptomatic scapulothoracic crepitus and bursitis

Division of Sports Medicine, Section of Orthopaedic Surgery, University of Michigan Medical Center, Ann Arbor, USA.

Scapulothoracic crepitus and scapulothoracic bursitis are related painful disorders of the scapulothoracic articulation. Scapulothoracic crepitus is the production of a grinding or snapping noise with scapulothoracic motion, which may be accompanied by pain. Scapulothoracic bursitis manifests as pain and swelling of the bursae of the scapulothoracic articulation. Scapulothoracic bursitis is always seen in patients with symptomatic scapulothoracic crepitus, but may exist as an isolated entity. Symptomatic scapulothoracic crepitus may be due to pathologic changes in the bone or soft tissue between the scapula and the chest wall or may be due to changes in congruence of the scapulothoracic articulation, as seen in scoliosis and thoracic kyphosis. Treatment of patients with symptomatic scapulothoracic crepitus begins with nonoperative methods, including postural and scapular strengthening exercises and the application of local modalities. When soft-tissue lesions are the cause of scapulothoracic crepitus, conservative treatment is highly effective. When symptomatic scapulothoracic crepitus is due to osseous lesions, or when conservative treatment has failed, surgical options are available. Partial scapulectomies have produced satisfactory outcomes in selected patients. Recently, open and arthroscopic scapulothoracic bursectomies have been performed with some success and are being used more frequently.
