RESUMEN
Hammertoe deformity correction surgery is one of the most common procedures performed by foot and ankle surgeons. Recent foot and ankle medical literature presents conflicting opinions regarding the optimal intramedullary fixation device and techniques for use in digital deformity correction. There are a number of varying fixation constructs of intramedullary Kirschner wire fixation reported for proximal interphalangeal joint arthrodesis; however, there are no reports of relative loading strength of the fixations. In this study, 90 sawbone models were divided equally into 3 groups of different intramedullary Kirschner wire fixation techniques: Group A- single straight, Group B- single bent, Group C- double bent. Each fixation construct underwent controlled axial loading and failure points were observed. Results showed no significant difference in load failure from all 3 groups with mean maximum force of Group A = 20N, Group B = 19.1N, and Group C =17.5N. We conclude that all Kirschner wire fixation options for digital deformity correction, will provide similar resistance to sagittal plane axial loads.

Coalitions of the hindfoot are a relatively rare but challenging condition encountered by foot and ankle surgeons. Those that manifest between the cuboid and navicular (cubonavicular coalitions) are seen even more infrequently and are estimated to comprise â¼1% of all tarsal coalitions. Treatment for cubonavicular coalitions parallels protocols for more common hindfoot coalitions. Typically, resection versus hindfoot arthrodesis procedures are used. The present study describes the case of a 34-year-old male with a painful cubonavicular coalition and early secondary signs of arthrosis. Despite the recommended guidelines of hindfoot arthrodesis, he elected for surgical resection. Autogenous adipose tissue and cryopreserved amniotic membrane were used for interposition at the resection site. This case demonstrates that surgical resection with interpositional grafting can be successful even in advanced disease states.
