Abstract

Abstract:

Objective

Exploring the short-term clinical efficacy of femoral locking plate combined with cortical bone plate in the treatment of bone defect induced femoral fractures and non union.

Methods

A retrospective analysis was conducted on 24 cases of postoperative femoral non union admitted to the bone trauma ward of our hospital from August 2016 to August 2021. 16 male patients and 8 female patients.

Results

The average age is 22-65 （41.54±13.46） years old. All patients were treated with femoral locking plates combined with allogeneic cortical bone plates. Harris and HSS scores are used to evaluate hip and knee joint function.Further evaluation includes surgical time and intraoperative blood loss.The average follow-up period for 24 patients was 12-16（13.58±1.32）months.All patients showed bone healing on imaging，and no limb deformities were observed；The average healing time is 4-13（6.38±2.06）months.In the last follow-up， the Harris score ranged from 69.2 to 96.6 （87.23±6.33）， with 10 cases being excellent， 11 cases being good， 2 cases being average， and 1 case being poor. The excellent and good rate was 87.5%； The HSS score ranges from 72 to 96（83.91±7.62），with 15 cases being excellent，7 cases being good，1 case being average，and 1 case being poor；The excellent rate is 91.7%.The average surgical time and intraoperative blood loss were 90-160（123.42±15.52）minutes and 340-600（438.75±78.87）mL，respectively.

Conclusions

The use of femoral locking steel plate combined with cortical bone plate for the treatment of bone defect induced femoral non union can achieve initial mechanical stability of the femur and long-term biological stability；Meanwhile， autologous iliac bone can effectively induce osteogenesis， and the combination of steel plates?and bone plates increases the stability of the femoral fracture end， achieving both mechanical and biological bone reconstruction，greatly increasing the probability of fracture healing.
