不同病因股骨头坏死的临床特征分析

Objective To explore the compositions and clinical characteristics of osteonecrosis of the femoral head (ONFH) with different etiology. Methods From January 2000 to August 2008, 602 cases (1036 hips) of ONFH were collected to analyze the compositions, age, incubation, ARCO stage and the rate of misdiagnosis of different etiology. Results In corticosteroid group, there are 280 cases (518 hips). They included 160 males and 120 females with an averaged age of 35.58±10.87 years old. The times from taking corticosteroid to the onset of pain were 25.95±34.94 months. 37 cases have been misdiagnosed. The mean stage was 2.48±0.76 according to ARCO staging system. In alcoholic group, there are 194 cases (346 hips). They included 193 males and 1 female with an averaged age of 41.55±9.09 years old. The times from taking alcohol to the onset of pain were 183.68±86.17 months. 55 cases have been misdiagnosed. The mean stage was 2.69±0.67. In traumatic group, there are 52 cases (52 hips). They included 25 males and 27 females with an averaged age of 41.63±15.84 years old. The times since injury to the onset of pain were 24.13±27.85 months. No misdiagnosed. The mean stage was 2.90±0.77. In idiopathic group, there are 52 cases (77 hips). They included 30 males and 22 females with an averaged of 40.87±14.24 years old. 14 cases have been misdiagnosed. The mean stage was 2.55±0.77. In corticosteroid combined with alcohol group, there are 19 cas-es (36 hips), including 19 males with an averaged age of 40.42±11.64 years old. 5 cases have been misdiag-nosed. The mean stage was 2.61±0.63. Conclusion Traumatic ONFH have more advanced ARCO stage and lowest misdiagnosis when complained with discomfort. Corticosteroid drugs is the main cause of ONFH, which affect younger person than other groups, with lower misdiagnosis. Most of alcoholic ONFH occurred in male.
