Abstract Objective To observe the clinical effect of the lateral reduction of proximal femur and internal fixation with locking compression paediatric hip plate （LCP PHP） for the treatment of femoral inter and subtrochanteric fractures in children. Methods There were 26 cases of femoral inter and subtrochanteric fracture treated with LCP PHP plate in Beijing Jishuitan Hospital from August 2010 to March 2016 were selected as study object. Beaty standard imaging evaluation methods were used for evaluation of imaging data, fracture healing time and complications were recorded, and hip function was evaluated according to Sanders standard. Results A total of 16 patients were followed up satisfactorily with an average follow-up time of 10 （7.25, 13.75） months. All the 16 patients were satisfied with the postoperative imaging data. 14 patients had normal bone healing through X-ray examination results. The average healing time was 11（7.75, 16.00） weeks. No complications occurred during follow-up. One patient with femoral subtrochanteric fracture combined with multiple fractures had internal fixation fracture due to delayed union of fracture, and the proximal humerus lateral plate （Philos system） internal fixation was used laterally to obtain bone healing. One patient of intertrochanteric fracture due to poor healing lead to failure of internal fixation, leading to coxa varus. About hip function, 12 cases were excellent, 3 were good, and 1 was middle of the 16 cases; among the 16 cases, 11 cases of intertrochanteric or simple subtrochanteric fracture were all excellent in hip joint function. Conclusion LCP PHP internal fixation system is used to treat the femoral inter and subtrochanteric fractures in children. The postoperative internal fixation is stable, the fracture healing is fast, and the postoperative complications are less. It can shorten the time of external fixation and facilitate the early functional exercise to restore the hip function, with high clinical value.
