Comparison of clinical effects of minimally invasive femoral head replacement and proximal femoral nail antirotation in the treatment of comminuted intertrochanteric fracture in the elderly / 中国骨伤

ABSTRACT

OBJECTIVE@#To analyze the clinical effect of minimally invasive femoral head replacement and proximal femoral nail antirotation(PFNA) internal fixation at the same time in the treatment of elderly patients with comminuted intertrochanteric fracture.@*METHODS@#From April 2020 to October 2020, 76 elderly patients with comminuted intertrochanteric fracture treated by minimally invasive femoral head replacement and PFNA were analyzed retrospectively. There were 35 patients in the prosthetic group, including 24 females and 11 males with an average age of (86.2±6.1) years old. There were 41 patients in PFNA group including 28 females and 13 males with an average age of (84.6±5.3) years old. The operation time, intraoperative blood loss, postoperative ambulation time, hospitalization time and complications were observed and compared between two groups. Harris hip score was performed at 1, 6 and 12 months after operation.@*RESULTS@#All patients were followed up for 13 to 17 months with an average of (14.3±1.4) months. The operation time of the prosthesis group was longer than that of the PFNA group (P<0.05);the amount of bleeding in PFNA group was less than that in prosthesis group (P>0.05);the time of ambulation in prosthetic group was earlier than that in PFNA group(P<0.05);the number of complications in the prosthesis group was less than that in the PFNA group(P<0.05); the Harris score of prosthesis group was significantly higher than that of PFNA group at 1 and 6 months after operation (P<0.05), but there was no significant difference in Harris score between two groups at 12 months after operation(P>0.05);the number of complications in the prosthesis group was less than that in the PFNA group (P<0.05).@*CONCLUSION@#Minimally invasive femoral head replacement is a good choice for the elderly patients with commuited intertrochanteric fracture. It can improve the quality of life and reduce the burden of family members and society.
