Comparison of cannulated screw and kirschner wire in the chevron osteotomy of hallux valgus

This study aimed to compare the outcomes of Chevron osteotomy for hallux valgus fixation using a cannulated screw versus a Kirschner wire.
This study included 20 feet of 23 patients with hallux valgus fixed with a cannulated screw (Group A) and 22 feet of 18 patients with hallux valgus fixed with a Kirschner wire (Group B) between 2015 and 2020. We excluded one patient who was infected and three patients who could not be contacted. We evaluated our patients retrospectively.
No significant difference was found between the postoperative early- and late-stage hallux valgus angles in both groups (P > 0.05). Likewise, no significant intergroup difference was not found between the postoperative early- and late-stage intermetatarsal angle values (P > 0.05). Patients in Group B were followed up for an average of 18.2 months, whereas patients in Group A were followed up for an average of 17.4 months. No significant difference was observed between the two implants in terms of the union time of the osteotomy line (P > 0.05). The time to union was significantly longer in the male patient group than in the female patient group, regardless of the type of implant used.
