<p><b>OBJECTIVE</b>To study diagnosis and therapeutic efficacy of transient oeteoporods of the hip (TOH).</p><p><b>METHODS</b>From January 2005 to February 2010, 5 patients with TOH were treated with traditional methods. All the patients were male, with an average age of 38.6 years (ranged, 27 to 46 years). The clinical manifestation, physical examination and imageology characteristic was investigated. The therapeutic efficacy was evaluated by Harris hip score.</p><p><b>RESULTS</b>All the patients were followed up, the duration ranged from 12 to 36 months (averaged, 24 months). The Harris hip score before treatment were 63.1, 86.0, 74.9, 63.6 and 64.8 respectively, while after 6 months treatment, the scores improved to 90.5, 94.5, 89.7, 93.9 and 87.8 respectively.
