Purpose:The authors intended to evaluate the results of symptomatic bunionette treated with a diaphyseal oblique osteotomy.
Material and Methods : Nine patients were followed for more than 1 year after diaphyseal oblique osteotomy for a bunionette deformity with plantar callosity. The mean age was 43 years (23-69 years), and the mean follow-up period was 27 months (12-70 months). As a combined disorder, 7 patients had hallux valgus, for which 3 distal metatarsal oteotomies, 3 proximal osteotomies, and 1 double osteotomy were performed. Clinically, preoperative and postoperative AOFAS MP-IP scale, patient’s satisfaction, postoperative complications were analyzed. Radiologically, the 4th intermetatarsal angle and the 5th metatarso-phalangeal angle were analyzed.
Results: Clinically, AOFAS MP-IP scale was increased from 59 points preoperatively to 93 points postoperatively, and all patients were satisfied with the results. The plantar callosity had all disappeared at the final follow up. The 4th intermetatarsal angle was decreased from 12.6° preoperatively to 4.3° postoperatively, and the 5th metatarsophalangeal angle was decreased from 21.9° preoperatively to 2.4° postoperatively. There were no significant postoperative complications.
Conclusion: Diaphyseal oblique osteotomy of the 5th metatarsal appears to be safe and satisfactory procedure for the treatment of a symptomatic bunionette with plantar callosity.
