The Clinical Results of Total Hip Replacement Arthroplasty for Infection Hip Sequelae with Dislocation and Severe Shortening / 대한정형외과학회잡지

ABSTRACT

PURPOSE: The purpose of this study is to evaluate the results of total hip replacement arthroplasty (THRA) in sequelae of the infected hip with dislocation and severe shortening. MATERIALS AND METHODS: We reviewed 22 cases of THRA performed from January 1985 to March 1995, for painful, dislocated hips secondary to infection in childhood, with shortening of the limb more than 5 cm. Among 22 cases, seventeen were pyogenic infection sequelae, and five were tuberculous infection sequelae. RESULTS: Mean followup period was 44 months (range: 24-111 months) . The mean value of the Harris score was increased to 86.7, which had been 61. The mean postoperative limb-length discrepancy was 1.8 cm and amount of correction ranged from 2.5 cm to 6.1 cm (average : 4.2 cm) . There was remarkable difference between the Crowe Group I and combined Group II and III in correction of shortening. The incidence of radiological loosening was not related to preoperative morbid period or the age of patients. CONCLUSION: The main resistant factor in lengthening of the affected limb was soft tissue contracture related to old age or long term after infection, and complication rate (14%) was higher than that in the other kinds of disease on hip.
