title: The Reverse Ludloff Osteotomy for Bunionette Deformity.
abstract: Background The typical bunionette deformity often presents as pain over the lateral margin of the fifth metatarsal head. There have been numerous operative treatments described for this pathology. The purpose of this study was to evaluate the results after a reverse Ludloff osteotomy in cases of severe bunionette deformities. Methods Between 2008 and 2012, 16 patients received a reverse Ludloff osteotomy of the fifth metatarsal due to a symptomatic type II or III bunionette that failed nonoperative treatment. We retrospectively reviewed charts, radiographic images, postoperative AOFAS (American Orthopaedic Foot and Ankle Society) lesser toe scores, and the EQ-5D at a mean of 41.9 months (range, 31-74 months) of follow-up. Additionally, limitation in activities of daily living, pain, and patient satisfaction were assessed. Results At latest follow-up, the mean AOFAS lesser toe score was 86.6 points and the mean EQ-5D score was 14.1. Fifteen patients had no or only little limitations. Fifteen out of 16 patients were satisfied or predominantly satisfied. Radiographic analysis showed for type II deformities a correction of the lateral bowing from 8.1° down to 0.67° (P < .001). The fourth-fifth intermetatarsal angle (4-5 IMA) improved from a mean of 13.2° to a mean of 5.2° (P < .001). The length of the fifth metatarsal was unchanged (P > .05). There were no observed complications, and no revision was necessary. Conclusion In the present study, the reverse Ludloff osteotomy had a high satisfaction rate and no complications. It provided radiographic correction of the deformity and may be considered in the surgical treatment of severe bunionette deformities.
