Purpose: Although the dicision of treatment method regarding to combined hammer toes deformity before operation for hallux valgus is necessary, there is no definitive principle about necessity of deformity correction. This study was performed to evaluate the clinical outcomes following combined surgery for hallux valgus and hammer toes deformity.
Materials and Methods: Twenty-eight cases underwent surgery for hallux valgus concomitant with hammer toes deformity were followed up for at least 1 year. The clinical evaluation was performed according to the American Orthopaedic Foot and Ankle Society(AOFAS) score, patient’s satisfaction score, pain scores. As the radiographic evaluation, hallux valgus angle(HVA), intermetatarsal angle(IMA), and the period to bone union were measured. In addition, the preoperative expectation and postoperative satisfaction of patients about hammer toes deformity, complication rate were analyzed.
Results: AOFAS score had improved significantly to 93.2 points at the last follow-up. The pain score of big toe and lesser toe had improved significantly to 1.1, 0.6 points. HAV and IMA had improved significantly to 14.6°, 10.2°. All cases achieved union of osteotomy site, and the period to union was average 7.8 weeks. On preoperative expectation of patients, the correction of hammer toes deformity was ranked third, following the improvement of big toe pain and the correction of hallux valgus. The patient’s satisfaction score at the last follow-up was average 93.4 points, and the importance of lesser toe operation was 29.8%.
Conclusion: Combined operation for hallux valgus and concomitant hammer toes deformity seems to be considerable treatment method, because of high preoperative expectation and high postoperative satisfaction, reliable pain relief, improvement of gait ability and cosmetic appearance.
