[Idiopatic chondrolysis of the hip. Long-term follow-up of a case].

Idiopathic chondrolysis of the hip is a very rare disease occurring during adolescence. Pain and limp are the most common symptoms and are a consequence of an accelerated loss of the articular cartilage with a lower range of move-ment producing rigidity in the last instance. The natural history is unpredictable and varies between complete and spon-taneous recovery and the ankylosis. The current recommended treatment is conservative, restricting the surgical option for residual stiffness. A clinical case of an eleven year old patient is presented. He consulted for a 2 year, torpid course of left groin pain with limp and rigidity. He received treatment with rest, discharge, analgesics and rehabilitation without any improvement initially. He was treated conservatively with NSAIDS, extremity discharge periods, soft traction in the hospital and at home and rehabilitation, recovering mobility and normal gait 6 years after the beginning of the symptoms. Twelve years after the onset of the symptoms the patient leads a normal life without symptoms and has a symmetric range of motion of both hips.
