The main objective in an Akin osteotomy is to maintain the lateral cortex of the phalanx as an additional point of fixation. But in patients with poor bone stock, the cortex is thin and brittle, and it is easy to break the cortex during reduction.

Maybe, an oblique oriented osteotomy reduces the chance of hinge failure, as it was suggested by Boberg et al.4 But a perpendicular oriented osteotomy to the long axis of the proximal phalanx achieves a greater degree of correction and more stable fixation. Douthett et al3 reported 47 intraoperative lateral cortex phalanx disruptions in 132 patients, and 88.6% of the osteotomies were perpen-dicular to the longitudinal axis of the phalanx. Additional fixation is often required when a lateral cortex disruption happens.

Multiple methods of fixation have been published in the literature. Staples are easy to u...
