Treatment of Hammertoe Deformity Using a One-piece Intramedullary Device: A Case Series

Hammertoe Correction With Interphalangeal Joint Arthrodesis

“…13,14 In 2012, a case series demonstrated the successful use of a 1-piece hammertoe system in 7 toes in 3 patients. At approximately 1 year postoperative, no complications were seen and all patients were satisfied with the cosmetic appearance of their corrected toes.…”

“…At approximately 1 year postoperative, no complications were seen and all patients were satisfied with the cosmetic appearance of their corrected toes. 13 In 2013, we reported a review of our past 253 hammertoe corrections. 14 Of the 63 Pro-Toe VO hammertoe implants used, only 4 patients developed a malunion, all being asymptomatic.…”

“…Recent studies have demonstrated successful patient outcomes and low complication rates using various 1-piece implant designs for intramedullary hammertoe correction. [13][14][15][16] The purpose of the article is to describe the indications and surgical technique for hammertoe correction using a 1-piece intrameduallary fixation device for PIPJ arthrodesis.…”

Dual-Component Intramedullary Implant Versus Kirschner Wire for Proximal Interphalangeal Joint Fusion: A Randomized Controlled Clinical Trial

“…The degree of bone-to-bone contact remained constant thereafter, because each component of the implant was screwed into the corresponding phalanx and, as such, could not piston, rotate, or flex. Resistance to flexion, rotation, and pistoning is a feature of certain intramedullary fixation devices that are threaded, those that effect interfragmental compression, and those that are not simply round in the cross-section (15). If desired, the surgeon could position the components of the intramedullary implant such that, on coupling, a gap will be maintained between the phalangeal surfaces.…”

“…It is characterized by concomitant flexion of the proximal interphalangeal joint (PIPJ) and hyperextension of the metatarsophalangeal joint (MTPJ) (3,4). Numerous procedures have been described for the correction of the HT deformity, ranging from interphalangeal (IP) arthroplasty with or without tendon transfer and temporary Kirschner wire (K-wire) stabilization to PIPJ fusion using any of a wide range of fixation devices, including a K-wire (5,6) or wires (7), sutures (8), single and multicomponent internal fixation devices (9)(10)(11)(12)(13)(14)(15), PIPJ fusion augmented with a bone graft (16), and combinations of interphalangeal (IP) manipulations with MTPJ relocation and stabilization (17). Regardless of the surgical technique used, the goals of surgery are to correct the deformity (or limit its progression) and alleviate pain.…”
