The "diagonal" principle in the surgery of femoral intertrochanteric fractures

Abstract Objective: To explore the role of "diagonal principle" surgical technique in the treatment of elderly femoral intertrochanteric fractures. Methods: From October 2015 to February 2018, we treated 28 cases of femoral intertrochanteric fractures (8 cases of AO / OTA classification 31A1 type, 12 cases of 31A2 type, and 8 cases of 31A3 type), and they all received extended pith internal nail (length ≥340mm) internal fixation surgery. Results: Hip function scores were excellent in 18 cases, good in 7 cases, poor in 1 case, and dead in 2 cases. The excellent and good rate was 89.3%. No internal fixation fracture, failure, or re-fracture occurred. Conclusion: The use of "diagonal principle" for the treatment of elderly femoral intertrochanteric fractures has promising results.
