Abstract:

Objective

Based on the multi-criteria decision-making model to evaluate the benefits and risks of artificial femoral head replacement (FHR) in the treatment of intertrochanteric fracture offemur(IFF).

Methods

Selected 94 patients with lateral wall comminuted IFF treated in our hospital from June 2018 to August 2022 were analyzed retrospectively. The patients were divided into PFNA group (47 cases,treated with PFNA internal fixation), there were 17 males and 30 females, with an average age of (74.29 ±8.09)years,and FHR group(47 cases,treated with FHR),there were 22 males and 25 females with an average age of(75.44±9.52)years.To establish a multi-criteria decision-making model of IFF treated with FHR for lateral wall comminution.

Results

There were differences in intraoperative blood loss, operation time,postoperative weight-bearing time, incision length, clinical effect, adverse reactions and hospital stay.There were differences in QOL-BREF score, coagulation function index and Harris score between the two groups.Compared with PFNA group, FHR group has higher benefit and lower risk. When both benefit and risk are important, the total benefit-risk value of FHR group and PFNA group is 75 and 62 respectively, and the observation group is 100% better than the control group.The stability of the multi-criteria decision evaluation model is good.

Conclusions

Compared with PFNA, the benefit of FHR in the treatment of lateral wall comminuted IFF outweighs the risk, and it could be used in clinical treatment of lateral wall comminuted IFF. Clinically, the benefit-risk of FHR in the treatment of lateral wall comminution of IFF may be better than that of PFNA.
