Artificial femoral head arthroplasty versus proximal femoral nail antirotation for the injured lateral wall Intertrochanteric fracture in elderly adults / 中国组织工程研究

ABSTRACT

BACKGROUND: For the treatment of intertrochanteric fracture in elderly patients, if there is no operative contraindication, surgical treatment is recommended. Operative methods include internal fixation and joint replacement. Surgical techniques are mature, but the choice of surgical methods is controversial. OBJECTIVE: To compare the efficacy of artificial femoral head arthroplasty and proximal femoral nail antirotation in elderly patients with injured lateral wall femoral intertrochanteric fracture so as to provide the basis of clinical method selection and to provide the original data for the systematic analysis of large sample. METHODS: According to the case criterion, 48 cases of AO classification of type A2.2, A2.3 intertrochanteric fractures were selected in Department of Orthopedics, the 71 Group Army Hospital of Chinese PLA from January 2012 to December 2017. They were divided into femoral head arthroplasty group (n=29) and proximal femoral nail antirotation group (n=19). All patients signed the informed consent. This study was approved by the Hospital Ethics Committee. The patients were followed up for 1-3 years. Operation time, bleeding volume, hospitalization expenses, the incidence of complications, and Harris hip score at 1 month and 1 year after the surgery were compared between the two groups. RESULTS AND CONCLUSION: (1) After statistical analysis, operation time was significantly shorter in the femoral head arthroplasty group than in the proximal femoral nail antirotation group (P 0.05). The cost of hospitalization was significantly more in the femoral head arthroplasty group than in the proximal femoral nail antirotation group (P 0.05). (3) There was no significant difference in the incidence of complications between the two groups (P > 0.05). (4) For the patients over 70 years old with intertrochanteric fracture of injured lateral wall, artificial femoral head replacement has the advantages of early getting out of bed, high quality of life and quick recovery of joint function. It is suggested to choose artificial femoral head replacement first.
