RESUMO
BACKGROUND:Unstable intertrochanteric fracture is often treated with proximal femoral nail anti-rotation (PFNA), which has good repair effect, but there is the risk of varus deformity. Reverse less invasive stabilization system (LISS) is a new treatment, which can avoid varus deformity. However, little evidence has focused on the comparison of PFNA and LISS. OBJECTIVE:To compare the clinical efficacy, complications and joint function of reverse LISS and PFNA in treatment of unstable intertrochanteric fractures in the elderly patients. METHODS:A retrospective analysis was performed among 64 elderly patients with unstable intertrochanteric fractures. Among them, 28 cases were treated with reverse LISS and 36 cases were treated with PFNA. The healing time, loading time, complications and Harris score of hip joint function after internal fixation were compared in the two groups. RESULTS AND CONCLUSION:The loading time in the LISS group was earlier than the PFNA group. The healing time, incidence of complications and Harris score of hip joint function showed no significant differences between the two groups (P>0.05). Reverse LISS internal fixation has similar efficacy and complication with PFNA for the treatment of senile unstable intertrochanteric fractures, and it is a reliable method for internal fixation with few complications.Subject headings:Femoral Fractures;Clinical Healing;Internal Fixators;Bone Nails;Fol ow-Up Studies
