The unstable intertrochanteric femur fracture remains a challenge for surgeons. However, few studies have compared the clinical effectiveness of intramedullary nail in combination with a reconstruction plate and intramedullary nail alone in the treatment of patients with unstable intertrochanteric femoral fractures with lateral wall damage.


This study retrospectively analyzed 16 patients with 31 A3 intertrochanteric fractures treated with the intramedullary nail in combination with reconstruction plate (the study group) and 19 patients with 31 A3 intertrochanteric fractures treated with intramedullary nail alone (the control group) between January 2012 and January 2018. The operation time, intra-operative blood loss, time of fracture healing, and complication rates of post-operative fixation failure were assessed between the two groups. At the follow-up of post-operative six and 12 months, Harris hip score (HHS) and the Parker-Palmer mobility score (PPMS) were used to evaluate the functional states and mobility levels.


The distribution of all basic characteristics was similar between the two groups (P ˃ 0.05). The study group had longer operation time and more intra-operative blood loss in comparison with the control group (P < 0.001), while the study group had shorter fracture healing time (P = 0.03) and lower fixation failure rate as compared with the control group. Regarding the functional outcome, the study group had higher HHSs and PPMS than the control group (P = 0.003).


Although intramedullary nails in combination with reconstruction plates had longer operation time and more intra-operative blood loss, it might be superior to intramedullary nail alone in terms of fracture healing time, fixation failure complication rate, and post-operative functional recovery.
