To evaluate the effectiveness and safety of core decompression in the treatment of avascular necrosis (AVN) of the femoral head. ⋯ Core decompression with cancellous bone grafting is a safe and effective procedure for the treatment of early AVN of the femoral head. Results with this form of treatment are considerably better than those obtained in patients treated nonoperatively. Decompression with or without bone grafting is the author's treatment of choice for patients with early AVN of the femoral head.

To familiarize the surgeon with problem-based learning (PBL) and to discuss the current and future role of PBL in undergraduate surgical education. ⋯ Centres that have adopted a PBL approach have found improved student motivation and enjoyment, but there has been no convincing evidence of improved learning. An intelligent combination of both traditional and PBL approaches will likely provide the most effective training for undergraduate surgical clerks.

Imaging studies are essential for the diagnosis and management of many of the hip disease entities dealt with in this symposium. This paper briefly touches on salient aspects of standard radiography, "special" views, arthrography, radioisotope imaging, computed tomography and magnetic resonance imaging. Orthopedic surgeons must be familiar with the correct applications and interpretation of these modalities so as to use them efficiently and economically.
