Fixation of the Proximal Interphalangeal Arthrodesis with the Use of an Intraosseous Loop of Stainless-Steel Wire Suture

Digital Arthrodesis With a One-Piece Memory Nitinol Intramedullary Fixation Device

“…Several methods for PIPJ arthrodesis when correcting digital deformities have been described in the literature including the use of k-wires, silicone implants, allograft bone, stainless steel wire suture, titanium screws, and absorbable screws. 1-13 Our focus in this study was to evaluate the efficacy of a 1-piece memory Nitinol intramedullary fixation device, when performing a PIPJ arthrodesis to correct digital deformities.…”

“…Success rates for these implants have been reported to range from 54% to 97%. 1-13 With 1-piece implants, fusion rates have been reported at 93%, with no additional surgeries or implant removal required. 4…”

“…1 Osseous procedures include joint arthroplasty or arthrodesis, each with its own well-described variations. 1-13 The goals of surgical correction are to relieve pain, eliminate the deformity, and create a rectus digit.…”

StayFuse for Proximal Interphalangeal Joint Fusion

“…Two patients found the toe to be "too straight." Other described techniques include the use of freeze-dried allograft cortical bone pins, 13 sutures, 8 pins 10 that address some of the problems with wires and screws. The potential for disease transmission and painful foreign body-related granulomas exists for these methods of stabilization.…”

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

“…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.…”
