Bunionette / Overlapping 5th Toe Deformity



- Discussion:
     - bunionette deformity may be created by wide 4-5 intermetatarsal angle;
     - symptomatic plantar callus is 2nd to concomitant plantar flexion of the fifth metatarsal;
     - soft corn caused by the pressure of the bone of the proximal phalanx of 5th toe (may be exacerbated by tight shoes);
     - soft tissue surgery will not solve the problem and the offending agent is usually the condyle of the proximal phalanx of 5th toe;
     - associated 5th toe cross over deformity:
           - 5th toe lies contracted in a dorsal medial direction over the 4th toe;

- Radiographs:  

- Treatment: Diaphyseal Osteotomy:
     - best method for correction is w/ long oblique osteotomy, which allows for medial displacement (and dorsiflexion if it is required)
