ABSTRACT
BACKGROUND:There is controversy on the treatment of old femoral neck fracture with hemiarthroplasty. OBJECTIVE:To observe the clinical effect of cementless hemiarthroplasty in the treatment of old femoral neck fracture, and to compare with total hip arthroplasty. METHODS:A retrospective analysis was performed on the clinical data of 23 old femoral neck fracture patients treated by artificial joint replacement from January 2009 to June 2010. Among the 23 patients, 11 cases were treated with cementless hemiarthroplasty, and 12 cases were treated with total hip arthroplasty. The time for off-bed activity, Harris score and the incidence of perioperative complications were compared between cementless total hip arthroplasty and hemiarthroplasty. RESULTS AND CONCLUSION:Al the patients were fol owed-up for 12-18 months. The active straight leg raising angle, time for off-bed activity, incidence of early postoperative complications and Harris score at 1 week after treatment of the cementless hemiarthroplasty group were better than those of the total hip arthroplasty group;there were no significant differences in Harris score at 6 weeks, 3 and 6 months between two groups;the incidence of forward hip pain of the cementless hemiarthroplasty group was higher than that of the total hip arthroplasty group. So, we general y think that cementless hemiarthroplasty has better short-term effect in the treatment of old femoral neck fracture, but the long-term integrated efficacy needs to be further identified.
