Abstract:
BACKGROUND:Hemiarthroplasty is a proven method for reconstruction of the hip joint function, especialy for the elderly patients who cannot tolerate the total hip arthroplasty. However, for the patients with osteoporosis, there are stil more controversial in clinical practice about using cemented or cementless femoral prosthesis for hemiarthroplasty. OBJECTIVE: To observe the repair effect of cemented or cementless femoral prosthesis when were used for hemiarthroplasty in patients with osteoporosis. METHODS:The clinical data from 105 patients treated with hemiarthroplasty were retrospectively analyzed. Osteoporosis was diagnosed in these patients using the dual energy X-ray absorptiometry before surgery.Patients were divided into bone cement group (n=56) and cementless group (n=49) depending on different types of femoral stem prosthesis. The difference of efficacy between cemented or cementless femoral prosthesis when were used for hemiarthroplasty in patients with osteoporosis was analyzed by comparing the operative time, volume of drainage, post-operative Harris scores of hip joint function and radiographic assessment (prosthesis subsidence, osteolysis, severe stress shielding, heterotopic ossification) during the folow-up after the replacement. RESULTS AND CONCLUSION:In the process of hemiarthroplasty in patients with osteoporosis, the operative time in the cement group was significantly longer than that in the cementless group (P < 0.05). However, there was no significant difference in the postoperative volume of drainage between these two groups (P > 0.05). At the 1, 3, 6 and 12 of folow-up after replacement, there were no significant differences in the Harris score of hip joint function, total effective rate and radiographic assessment between these two groups (P> 0.05). These results suggest that in the process of hemiarthroplasty in patients with osteoporosis, the clinical efficacy of cementless femoral prosthesis is similar to the cement femoral prosthesis, therefore two prostheses can al be selected; however, the operative time of the cement femoral prosthesis is longer than the cementless femoral prosthesis, so we can give priority to the cementless femoral prosthesis for patients with osteoporosis who can’t tolerate a long operative time because of the poor basic condition.
