ABSTRACT
The favourable results we achieved in primary THR with the ABG HA-coated hemispheric metal backed cup led us to use this same cup in revision arthroplasty. Changes in inclination and migration of the cup were measured, as well as the radiologic appearance of the bone-cup interface. The most important features are quick osseointegration and immediate stability. The early and three to five years results with the use of the ABG HA-coated cup in revision arthroplasty are promising.

A prospective study was performed over a period of 2 years to identify the cause of peroneal palsy following hip fracture treatment. Sixty-eight patients in Group I had their injured leg placed in traction in a splint with a metal frame. In Group II (66 patients) elevation only of the fractured extremity was maintained with a few pillows. There were five cases of peroneal palsy in Group I and none in Group II. The difference is significant. Direct pressure on the nerve in the area of the fibular head during the preoperative traction period seems to be the cause of this transient dysfunction.

Occipital condyle fractures are rarely reported in survivors of trauma. Most cases involve patients with a major head trauma, lower cranial nerve palsy, and/or suspected lesions demonstrated on plain x-ray films of the skull or cervical spine. The authors describe a traffic-accident victim in whom an atlanto-occipital joint lesion was suspected based only on mobility investigation of the skull. Axial high-resolution computerized tomography of the atlanto-occipital joint showed a fracture of the right occipital condyle.

To our knowledge, no case of occipital condyle fracture after minor head trauma in the pediatric population has been published. We report the case of a 12-year-old girl with a Jefferson's fracture detected on x-ray films. Axial high resolution computed tomography and coronal reconstruction images demonstrated the additional occipital condyle fracture.

The MRI features of a hibernoma have been described, as no previous report of MRI findings was found in the literature. The hibernoma presents as a well-delineated soft tissue mass with tissue attenuation intermediate between that of skeletal muscle and subcutaneous fat. Marked contrast enhancement is noted.

Three cases of femoral head fractures in a single car accident are described. The outcome of these relatively uncommon fractures after 14 months of followup is fair for the Pipkin Type I and II lesions and good for the Pipkin Type IV one. A review of consulted literature has been added.
