Abstract：Objective To assess the clinical value of combining primary total hip arthroplasty with autologous bone impaction grafting.Methods A retrospective analysis was conducted on 80 cases of primary total hip arthro-plasty treated at Zunyi First People's Hospital between January 2021 and January 2024.The patients were divided into two groups based on whether autologous bone impaction grafting was performed:the observation group(with autologous bone impaction grafting,n=40)and the control group(without autologous bone impaction grafting,n=40).Hip joint function,pain levels,neurological function,and prosthesis loosening were compared between the two groups.Re-sults Prior to treatment,there were no significant differences between the two groups in terms of hip joint function,pain levels,or the levels of nerve-specific proteins S-100B and NSE(P＞0.05).After treatment,improvements were observed in hip joint function,pain levels,and nerve-specific protein levels in both groups(P＜0.05).The observation group had significantly higher Harris scores(P＜0.001)and lower VAS scores(P＜0.001)compared to the control group.Addition-ally,the observation group exhibited lower levels of S-100B and NSE proteins compared to the control group(P＜0.05).Postoperatively,no patients in the observation group experienced prosthesis loosening(0.00％incidence),which was significantly lower than the five cases(12.50％incidence)of prosthesis loosening in the control group(P＜0.05).Con-clusion Combining autologous bone impaction grafting with primary total hip arthroplasty is beneficial for the recovery of hip joint function and neurological function,alleviates pain,and reduces the incidence of prosthesis loosening.
