Fracture separation of the coracoid process associated with acromioclavicular dislocation: conservative treatment--a case report and review of the literature.

Complete acromioclavicular dislocation associated with fracture separation of the base of the coracoid process is uncommon. This is a report of a 51-year-old man with severe emphysema and limited physical demands in whom the acromioclavicular dislocation and coracoid process fracture were treated conservatively with sling immobilization and early motion and exercises. Good power and full, painless range of motion with minimal symptoms was observed at 6 months follow-up. The strong coracoclavicular ligaments, rather than rupture, may avulse the coracoid process near its base and with disruption of the acromioclavicular joint may allow complete dislocation of the clavicle. A satisfactory result may be obtained without operative reduction of either the acromioclavicular joint or the coracoid process.

Total knee arthroplasty.

Over the past 15 years, total knee arthroplasty has evolved to a substantial degree with respect to both design and technique. Although initially it lagged well behind the "state of the art" for total hip arthroplasty, it now appears to have surpassed the older procedure, particularly with respect to durability. The management of severe deformities and the improvement of the eventual range of motion remain challenges, but both are being met with increasing success.

Posterior stabilization of pelvic fractures by use of threaded compression rods. Case reports and mechanical testing.

Threaded compression rods were placed between the posterior-superior spines as a means of posterior stabilization of pelvic fractures. To document the increase in sacroiliac stability afforded by this technique, biomechanical testing was performed. Malgaigne-type fractures with sacroiliac disruptions were created in four cadaver pelvises. The fractures were stabilized with anterior frames of the Slatis or Pittsburgh type and subjected to longitudinal and torsional loading patterns on an Instron machine. The anterior fixation was then augmented with threaded compression rods placed between the posterior-superior spines to compress the disrupted sacroiliac joints, and repeat testing was conducted. Anterior frames alone were found to provide little stabilization of the disrupted sacroiliac joints with either longitudinal or torsional loading. Markedly improved stabilization in both loading modes was achieved with posterior augmentation. Two typical cases are presented to demonstrate that posterior stabilization is as efficacious in clinical practice as in the biomechanics laboratory.

Ipsilateral supracondylar femur fractures following knee arthroplasty.

A retrospective study was performed to evaluate the treatment of five patients with prosthetic knee arthroplasty who sustained a supracondylar femoral fracture of the ipsilateral side. Four of the patients were initially treated by plaster immobilization or traction. Two of the four showed no signs of healing at three months postfracture and had to have open reduction and internal fixation. The fifth patient had primary open reduction and internal fixation. The three patients who were treated surgically regained their prefracture knee rating score. The two who were treated nonoperatively for their fracture had a significant loss in limb function and failed to regain their prefracture knee rating score. Open reduction and internal fixation of these fractures achieves the best results despite the complicating factors of in situ prosthetic components.
