This report describes a patient with a fracture of the manubrium of the sternum of a type which has not been reported previously. We discuss the incidence, the mechanism of production and the site of these fractures, and their treatment and prognosis.
Erosion of the insertions of tendons and ligaments in bone (i.e. of the enthesis) due to chronic aseptic inflammation causes reparative ossification. With regard to our clinical and radiological findings in ten patients hyperostosis of the sterno-clavicular joint seems to be the late stage of such an enthesopathy. Pain and swelling of the soft tissues and an elevated erythrocyte sedimentation rate are characteristics of this seronegative rheumatic disease. For visualizing the extraarticular changes in the sterno-costo-clavicular region tomography is necessary. Early diagnosis and consequent antiphlogistic therapy should remit pain and help avoid hyperostosis.
Scapulothoracic dissociation, although rare, causes significant morbidity and mortality by completely disrupting the attachments of the scapula to the axial skeleton with the skin remaining intact. The defining constellation of injuries is subclavian or axillary vascular disruption, lateral displacement of the scapula, separation of the clavicular articulations with or without fracture of the clavicle, and cervical nerve root avulsion or brachial plexus injury. Orthopedic stabilization, vascular repair, and brachial plexus exploration are mandatory. Above elbow amputation, either primarily or within 24 hours, is recommended for the flail extremity.

We report three cases of a rare late complication of neck dissection: anterior dislocation and hypertrophy of the sternal head of the clavicle manifesting as a hard lump in the lower neck. We describe the mode of presentation, etiology, and methods of prevention.

An analysis is presented of 20 patients with the human immunodeficiency virus (HIV) infection who were treated for skeletal infection in our hospital. Seventeen cases of septic arthritis and three of osteomyelitis were found. All patients were intravenous drug abusers, 75% were male and all were younger than 40 years old. Eighty-eight percent of the septic arthritis cases were monarticular, the hip joint being the area most commonly affected (29%), and Staphylococcus aureus and Candida albicans were the most frequently isolated agents (60% and 20%, respectively). Gram negative bacteria were not found. No correlation between the number of CD4 lymphocytes, affected joints, isolated microorganism or functional capacity was found. Four of 17 patients with septic arthritis and 2 of 3 with osteomyelitis fulfilled the CDC criteria for the diagnosis of acquired immunodeficiency syndrome (AIDS). All cases except one responded to conventional therapy. We conclude that skeletal infection in HIV-infected patients is more closely associated with the risk-group than with HIV itself.
Imaging of patients with pelvic trauma begins with a logical approach to plain radiographs. These films reveal the probable mechanism of injury and suggest a rationale for emergent reduction. Radiographs, along with the clinical impression, suggest the likelihood of associated soft tissue injury, possibly requiring further specific radiographic studies. Significant vascular injury most often accompanies disruption of the posterior pelvic ring. Bladder and urethral trauma may be suspected in any displaced type III pelvic fracture with suggestive clinical signs. Ideally, urethrography precedes bladder catheterization. Acetabular fractures must be recognized because of their implications for future hip joint function. CT is very helpful in definitive treatment planning of pelvic (especially acetabular) fractures but may be delayed until other life-threatening injuries have been addressed. Plain radiography is also well suited to evaluation of chest wall trauma. When multiple ribs are fractured in two places, the radiologist should suggest the possibility of flail chest. Sternal fractures and multiple rib fractures, including the first three ribs, may herald life-threatening vascular or cardiac damage. To summarize, the radiologist contributes most to the care of the trauma patient by recognizing roentgen patterns of injury, knowing which are commonly accompanied by damage to critical soft tissues, and performing the indicated radiographic studies efficiently.
Five cases of total claviculectomy are described to demonstrate that the functional results are excellent. A review of the literature supports the concept that the clavicle is an accessory to the body skeleton and that patients can function well without its bony support. The exception is dysfunction of the trapezius.
