Observation on the effect of different hip replacement surgeries on hip function in patients with acetabular fractures and postoperative complications

Abstract

Objective To study the effect of different hip replacement surgeries on hip function in patients with acetabular fractures and observe postoperative complications. Methods Ninety-six patients with acetabular fractures treated in our hospital between January 2011 and December 2014 were divided into observation group (n=51) and control group (n=45) according to different surgeries. Under general anesthesia, the patients in observation group were treated by total hip replacement, and the patients in control group were treated by total hip resurface replacement. Hip function score (Harris score) before and 1 month, 1 year after surgery, hip range of motion, and complications were compared between two groups. The degree of hip pain was compared between two groups by numerical rating scale (NRS). Results Harris score significantly improved in two groups 1 month, 1 year after surgery, those 1 year after surgery were significantly higher than those 1 month after surgery, with statistically significant differences (P 0.05). The range of motion of hip flexion, abduction, adduction, extorsion, and intorsion in two groups 1 year after surgery were significantly larger than those before surgery, with statistically significant differences (P 0.05). The degree of hip pain in two groups after surgery significantly decreased, with statistically significant differences (P 0.05). Conclusions The effect of total hip replacement and total hip resurface replacement on hip function are similar. Both can relieve hip pain, with few complications. Therefore, surgery can be chosen according to patients' condition and needs. Key words: Hip replacement; Acetabular fractures; Hip function; Postoperative complications
