  • Comparison of the predictive value of tip-apex distance and calcar referenced tip-apex distance in treatment of femoral intertrochanteric fractures with Asian type proximal femoral nail fixation

    ObjectiveTo compare the predictive value of the two concepts for complications by comparing the incidences of surgical complications associated with different tip-apex distance (TAD) and calcar referenced tip-apex distance (Cal-TAD) in the treatment of femoral intertrochanteric fractures with Asian type proximal femoral nail (APFN) fixation. MethodsA total of 188 cases of femoral intertrochanteric fractures treated with APFN fixation between January 2014 and December 2018 were collected according to inclusion criteria. TAD and Cal-TAD were measured on the X-ray film at immediate after operation; the patients were divided into two groups according to the measurement results: <25 mm and ≥25 mm. Gender, age, and fracture side and AO type were recorded. The patients in each group were reviewed whether there was delayed fracture union or nonunion, whether the screw blade moved axially, whether the femoral neck collapsed or even screw blade cut out, whether the internal fixator became loose or broken within 12 months after operation. Then statistical analysis was performed. ResultsThere were 119 patients with TAD<25 mm and 69 patients with TAD≥25 mm, and 142 patients with Cal-TAD<25 mm and 46 patients with Cal-TAD≥25 mm. There was no significant difference in gender, age, or fracture side and AO type between groups (P>0.05). During the follow-up, 6 patients (5.04%) with TAD<25 mm, 10 patients (14.49%) with TAD≥25 mm had complications, and 1 patient (0.70%) with Cal-TAD<25 mm and 15 patients (32.61%) with Cal-TAD≥25 mm had complications. There were significant differences in the incidence of complication between the patients with different TAD, between the patients with different Cal-TAD, and between patients with TAD<25 mm and Cal-TAD<25 mm (P<0.05). ConclusionIn the operation of femoral intertrochanteric fracture with APFN fixation, surgical complications can be significantly reduced when TAD or Cal-TAD was controlled within 25 mm, Cal-TAD is more significant in the prediction of postoperative complications.
