Introduction: Minimally invasive hallux valgus corrective osteotomies have gained popularity in recent years, with several implant options used to stabilize osteotomies. We aim to report the early radiological outcomes of the Spear plate intramedullary system used in minimally invasive hallux valgus correction in Asian patients.
Materials and methods: A total of 17 patients (22 foot) who underwent minimally invasive distal metatarsal osteotomy for hallux valgus correction with the Spear plate intramedullary system between June 2020 and February 2022 were included in this study. All patients were followed up for a minimum of 3 months when the radiological bony union of the osteotomy site was evident. Preoperative and postoperative hallux valgus angle (HVA), first–second intermetatarsal angle (IMA), and tibial sesamoid position (based on the Hardy and Clapton system) on weight-bearing dorsoplantar foot radiographs were measured.
Results: The mean radiological follow-up period was 4.4 months (range, 3.0–10.0 months). Radiographic analysis showed the HVA, IMA, and tibial sesamoid position all improved significantly postoperatively after a minimally invasive hallux valgus correction with the Spear plate. All cases showed union of the osteotomy sites by postoperative 3 months.
Conclusion: The Spear plate system is a reasonable option for stabilization of a minimally invasive Bosch osteotomy in the correction of hallux valgus.
