BACKGROUND: There has been increasing interest in the use of percutaneous osteotomy techniques for bunionette (tailor's bunion) correction. This study evaluated clinical and radiographic outcomes following an unfixed, percutaneous oblique distal metaphyseal-diaphyseal osteotomy and compared outcomes between complete and incomplete osteotomy groups.
METHODS: A total of 43 feet (mean age 54.2 ± 17.1) underwent percutaneous oblique distal osteotomy by a single surgeon over a 4-year period. The primary outcome was the presence of significant postoperative hypertrophic callus at the osteotomy site (>150% of the width of the fifth metatarsal shaft), which decreases over time due to normal bone remodeling. Secondary exploratory outcomes included the radiographic parameters fourth-fifth intermetatarsal angle (IMA) and metatarsophalangeal angle (MPA), and patient-reported outcome measures (PROMs) of Manchester-Oxford Foot Questionnaire (MOXFQ), EuroQol 5-Dimension, 5-Level (EQ-5D-5L), and visual analogue scale (VAS) Pain (minimum 12 months' follow-up).
RESULTS: Thirty feet had a complete osteotomy, and 13 feet had an incomplete osteotomy with the lateral cortex remaining intact. In the complete osteotomy group, 60% of patients (P = .001) had callus equivalent to >150% of the metatarsal width at 6-week follow up; this reduced to 19% (P = .31) at 6 months and 0% (P = 1) at 12 months. No significant hypertrophic callus was observed in the incomplete osteotomy group. All PROMs, except EQ-5D-5L VAS, showed significant improvements (P < .05). The IMA and MPA significantly decreased postoperatively across both groups (P < .001). There were no significant differences between the incomplete and complete osteotomy groups at follow-up radiographically and clinically, except for the MOXFQ Walking/Standing Domain (P = .014), where patients in the incomplete osteotomy group demonstrated greater improvement.
CONCLUSION: Unfixed, minimally invasive oblique distal osteotomy for bunionette deformity is a safe and effective procedure that is associated with significant improvement in radiographic and clinical outcomes. Whether or not the osteotomy is complete does influence hypertrophic callus formation but does not significantly affect the radiographic or clinical outcomes.
LEVEL OF EVIDENCE: Level III, retrospective comparative study.
