Background:
Percutaneous, implantless basal closing wedge osteotomy (PIBCO) is a new technique for hallux valgus (HV) deformity correction that does not need internal fixation. We present this technique and its short-term clinical outcomes for moderate-to-severe HV deformities.
Methods:
A retrospective review of 162 feet in 114 patients who underwent PIBCO of the first metatarsal (MT1) was conducted. Follow-up averaged 18.5 months. Outcomes were assessed using the visual analog scale (VAS), hallux valgus angle (HVA), intermetatarsal angle (IMA), and radiologic union. Complications were also assessed.
Results:
Average VAS score improved from 6.2 to 1.0 (P < 0.001). HVA improved from 29.8° to 7.6° (P < 0.001). IMA improved from 14.5° to 6.3° (P < 0.001). A total of 8 major complications were noted (4.9%).
Conclusions:
Satisfactory HV deformity correction was achieved. However, some instances may require internal fixation in order to avoid complications related to instability and noncompliance of postoperative rehabilitation protocols.
