Hammertoe digital deformity correction is a very controversial topic among foot and ankle surgeons. Hammertoes are characterized by an extension deformity at the metatarsophalangeal joint (MTPJ) and flexion deformity at the proximal interphalangeal joint (PIPJ). Current treatment options are often guided by the patient's discomfort as well as the reducibility of the affected digit. Kirschner wires (K-wires) have long been considered the gold standard for hammertoe digital repair. Although K-wires are simplistic to use as fixation, they carry inherit risks such as pin tract infections, migration, and breakage. This has lead to multiple intramedullary hammertoe devices including the PROTOE intramedullary device. This paper will discuss the usage and benefits the PROTOE has to offer over the conventional K - wire.
