We report two sibs with a similar syndrome of abnormal external ears, peculiar facial features, nail hypoplasia, a bilateral fibrous fusion of the outer third of the clavicle and the scapular spine, and the absence of a normal acromioclavicular joint. The present patients represent the fourth and fifth cases of the oto-onycho-peroneal syndrome (MIM 259780).

BACKGROUND Surgery for clavicular shaft fractures is becoming more common but incisional and chest wall numbness reportedly occurs in 10% to 29% of patients. This may be the result of iatrogenic injury to the supraclavicular nerve branches. QUESTIONS/PURPOSES We determined if there was a predictable branching pattern of the supraclavicular nerve at the anterior clavicular border and determine...

Intra-articular punctures and injections are performed routinely on patients with injuries to and chronic diseases of joints, to release an effusion or haemarthrosis, or to inject drugs. The purpose of this study was to investigate the accuracy of placement of the needle during this procedure. A total of 76 cadaver acromioclavicular joints were injected with a solution containing methyl blue an...

The acromioclavicular (AC) joint may be affected by a number of pathologic processes, most commonly osteoarthritis, posttraumatic arthritis, and distal clavicle osteolysis. The correct diagnosis of a problem can usually be deduced from a thorough history, physical examination, and radiologic evaluation. Asymptomatic AC joint degeneration is frequent and does not always correlate with the presen...

A distinctive and consistent pattern of degenerative change was seen in 560 acromioclavicular joints from dry bone skeletons of subjects over 40 years of age. An appreciation of this characteristic configuration is helpful at operation or when introducing a needle into the joint.

Massive acromioclavicular joint (ACJ) cysts are an extremely rare cause of shoulder impairment and with limited consensus in its management. We present the first published case report of a patient with a massive ACJ cyst treated with a reverse total shoulder replacement with minimal ACJ excision arthroplasty.

A 44-year-old diabetic man with isolated septic arthritis of the left acromioclavicular joint (A-C) caused by Staphylococcus aureus is described. He was admitted to the Department of Rheumatology with clinical symptoms of left shoulder arthritis and fever. Laboratory findings showed leukocytosis, elevated levels of erythrocyte sedimentation rate and C-reactive protein, all indicating septic art...
