Cement augmentation of intertrochanteric fractures stabilised with intramedullary nailing

We studied 80 patients (56 females) with an average age of 84 years (range 80-94). All patients were suffering from osteoporosis (1 or 2 Singh score) and had an unstable intertrochanteric fracture, defined as a fracture with three fragments or more. Patients were divided in group A (40 patients), treated by a cement augmentation technique and group B (40 patients) treated by Gamma Nail conventional technique. Augmentation was performed with MetilMetacrilate (Mendec Spine, Tecres) inserted through the cannulated cephalic screw at its apex. Such parameters were evaluated as the length of operating time, early functional recovery using the Harris hip score, assessment with radiography of the TAD index and development of implant related complications. The HHS average score was 48.2 and 49.31 after 1 month post-operation, 54.37 and 53.56 after 3 months, 54.71 and 56.42 after 6 months, 57.91 and 59.86 after 12 months, in groups A and B, respectively. The average drop of haemoglobin was 1.55 g/dL and 1.05 g/dL, in groups A and B, respectively. Except one joint penetration with the guide wire and some small amount of cement leakage, no other complications (infection, screw cut out and femoral head necrosis) were observed. We believe that in femoral intertrochanteric fractures cement augmentation could improve the mechanical stability of the implant, ensuring early functional recovery.
