Background: Screws have been recommended for fixation of the site of the metatarsal osteotomy. Methods: A report is presented on one surgeon's experience with a temporary, single Kirschner wire instead of screws for fixation of metatarsal neck osteotomies combined with proximal interphalangeal (PIP) joint resection arthroplasty in patients with dislocated metatarsophalangeal (MTP) joints and severe hammertoe deformities. Eleven consecutive patients (13 toes) were treated between January 1999 and January 2002 (mean age, 69 years; range, 44–81 years; seven women, four men) at a tertiary care foot and ankle center. Records and radiographs were reviewed retrospectively, and all patients were examined at follow-up by one of the authors (mean follow-up, 13 months; range, 6–32 months). Results: All 13 metatarsal neck osteotomies had clinical and radiographic union by 6 weeks, with no evidence of nonunion, malunion, avascular necrosis of the metatarsal head, deep wound infection, pin-tract infection, broken pins, or other serious complications. Two metatarsals (18%) had minor residual plantar calluses beneath the metatarsal head. The mean postoperative American Orthopaedic Foot and Ankle Society score was 76 of 95 points possible. All patients were satisfied with the procedure and would do it again. Conclusion: The use of a single, temporary K-wire provides adequate fixation for combined PIP joint resection arthroplasty and metatarsal neck osteotomy in patients with central metatarsalgia and severe hammertoe deformity.

Between January 1997 and July 2000, 10 patients with symptomatic bunionette deformity underwent 12 distal fifth metatarsal chevron osteotomies in which an absorbable poly- p-dioxanone suture (PDS) pin was used for fixation. Of the 10 patients, nine were female. Average age at operation was 41 years (range, 23–70). Mean duration of follow-up was 48 months (range, 6–81). All patients obtained clinical and radiographic union by 6 weeks, and there was no radiographic evidence of osteolysis, displacement, or avascular necrosis of the metatarsal head at final follow-up. There were no serious complications. The average postoperative AOFAS score was 93 of 100 possible. All patients were satisfied with the procedure and would have it again. Distal chevron osteotomy with a single, nonpredrilled PDS absorbable pin for the correction of symptomatic bunionette deformity is a reliable and effective technique that provides adequate fixation without complications.

Background: This study reviewed the results, complications, and patient satisfaction rates of a modified technique of flexor-to-extensor tendon transfer for correction of lesser-toe deformities. Methods: Records of 38 patients (79 toes; 46 feet) were identified and reviewed retrospectively. The mean duration of clinical followup was 33 (range 6 to 121) months. The average age of patients was 65 (range 27 to 82) years; 32 were women (84%) and six were men. Results: In 89% of the toes (70 toes; 34 patients; 42 feet) patients were satisfied with the procedure and would have it again. Conclusions: The technique described for flexor-to-extensor transfer for correction of lesser-toe deformities resulted in few complications, no “floating” toes and high patient satisfaction.
