| Summary: | Aim: This study aimed to examine the effect of cable cerclage on reduction quality and union time in patients treated with cephalomedullary nails for subtrochanteric fractures.
Materials and Methods: 75 closed subtrochanteric fractures treated with cephalomedullary nails by two different surgeons with at least 10 months of follow-up were included in the study. Patients operated by Surgeon 1 were grouped as Group 1 (closed cephalomedullary nailing without cables, n=43), patients operated by Surgeon 2 with 1-2 cables as Group 2 (n=20), and those operated with 3-4 cables were grouped as Group 3 (open cephalomedullary nailing + cable fixation, n=12). Postoperative radiographs were evaluated for the presence of cables, the number of cables used, deformity, the residual gap between the fracture ends, and the union time.
Results: The cable fixation rate was calculated as 42.6%. There was a statistically significant relationship between cable use and the amount of gap (p=0.033). The average gap was 3.97 mm in patients without cables, 0.65 mm in patients with 1-2 cables, and 0.66 mm in patients with 3-4 cables. A positive correlation was found between the amount of gap and the time to union (Spearman's rho= 0.468, p=0.001). A statistically significant difference was found between Group 1 and Group 2 and also between Group 1 and Group 3 regarding the union time (p=0.007, p=0.001, respectively). The mean time to union was determined as 7.3 months in Group 1, 5.4 months in Group 2, and 5.7 months in Group 3.
Conclusion: Reducing the gap in the fracture line by using cables provides a better reduction, stability, and a shorter union time than fixation without a cable in subtrochanteric fractures treated with cephalomedullary nailing.
