Peroperative difficulties in fluoroscopy of the femoral head in massive obese patient: enhanced visualization by intra-articular contrast agent.

Peroperative fluoroscopic visualization of the femoral head in massive obese patient can be enhanced by the administration of intra-articular contrast agent into the hip joint. It provides safe alternative for compromised resolution during the introduction of femoral head screws. We report our experiences with one patient as a technical report and believe that in certain cases this method may be quite helpful.
