Effects of femoral offset reconstruction or non-reconstruction on hip joint function in total hip arthroplasty / 中国组织工程研究

ABSTRACT

BACKGROUND:Femoral offset reconstruction is significant for recovering strength of abductor and the balance of soft tissue tension surrounding hip joint, maintaining joint stabilization, restoring joint function, reducing limping after replacement, decreasing prosthetic abrasion, and the incidence of joint prosthesis dislocation. OBJECTIVE:To discuss effect of femoral offset reconstruction on hip joint function in total hip arthroplasty. METHODS:We comparatively analyzed 20 patients (20 hips) undergoing the modular prosthesis (S-ROM) total hip arthroplasty and 19 patients (20 hips) undergoing the one modular prosthesis (Corail) total hip arthroplasty at the same time. According to Harris hip score and radiography results, hip joint function and femoral offset reconstruction rate were comparatively studied in both groups. RESULTS AND CONCLUSION:No infection, fracture, dislocation, deep venous thrombosis or neurovascular injury occurred in either group. Clinical fol ow-up results:In the modular prosthesis and one modular prosthesis groups, there was no significant difference in preoperative Harris hip score between the femoral offset reconstruction and non-reconstruction groups (P>0.05). At 12 months and the latest fol ow-up, the Harris hip score was higher in the patients with femoral offset reconstruction than those with femoral offset non-reconstruction (P0.05). These results indicated that functional recovery and the range of abduction were better in patients with femoral offset reconstruction than those without femoral offset reconstruction. Modular prosthesis has a high rate of femoral offset reconstruction.
