To assess the cause of hip lesions when combined with pelvic posterior inclinatiop such as osteoarthritic and rapidly destructive coxopathy-like changes, coverage of the femoral head to the acetabulum was measureed on computed torn ograms of 35 patients, and the relationship between degree of inclination and coverage was investigated. Patients were divided to in three groups according to their degree of pelvic posterior inclination: Group 1; less than 20° of inclination, 18 hips; Group 2; 21-25°, 6 hips; Group 3; more than 26°, 11 hips.There was no statistical difference in total coverage of the head among the three groups. Coverage of the anterior part of the head decreased and coverage of the posterior part of the head increased with an increase in posterior inclination.These findings suggest that the decrease in anterior coverage of the head with increasing pelvic inclination may lead fo the developmenf of some hip lesions.
