Clinical Comparison Between Shortening Osteotomy of the Proximal Phalanx Neck and Arthrodesis in Hammer Toe Surgery at Mid-TermFollow-Up



Clinical Comparison Between Shortening Osteotomy of the Proximal Phalanx Neck and Arthrodesis in Hammer Toe Surgery at Mid-TermFollow-Up



Journal of Foot and Ankle Surgery 58(2): 221-225



The treatment of hammer toe has been advocated for years, and many procedures have been proposed with skeletal and soft tissue intervention. The purpose of the present study was to compare arthrodesis of the proximal interphalangeal joint with shortening osteotomy of the proximal phalanx neck. In most cases, both procedures have been associated with elongation of the extensor apparatus, capsulotomy of the metatarsophalangeal joint, and stabilization with a Kirschner wire. To experiment with a technique that respects the anatomy and joint function, we used a distal subtraction osteotomy of the proximal phalanx neck. We compared a series of 78 patients, divided in to 2 groups: 38 (48.7%) treated with arthrodesis and 40 (51.3%) with shortening osteotomy. Patients were aged 22 to 78 years, with a mean final follow-up period of 56.6 (range 24 to 96) months. For clinical evaluation, we used the American Orthopaedic Foot and Ankle Society score, Foot and Ankle Outcome Score, and a subjective rating scale. The results were comparable between the 2 techniques; however, we report faster functional recovery in the group treated with shortening osteotomy (p < .0001), with an adjunctive advantage of preserving the integrity of the proximal interphalangeal joint. Thus, according to our results, this technique is comparable to arthrodesis.
