New Option For Hammertoe Fixation
Until now, options for hammertoe fixation haven’t been ideal. Simply fusing the joint with a K-wire alone is fast but often not effective. Intramedullary fixation, on the other hand, is time-consuming, complex, and expensive.
ExoToe offers a new option. It’s the first and only extramedullary device that’s just 0.6mm thin. And it’s the only implant to preserve the bony canal.
EASY, FAST, AND ADJUSTABLE
Interoperative anatomic angle adjustability. Only interoperative adjustable implant that allows straight or customized angle adjustability
Extramedullary device that preserves medullary bone allowing ExoToe to be used as a primary hammertoe device or for hammertoe revision cases
Allows for K-Wire to be used in conjunction with the implant to stabilize the MTPJ
Easily removed using a Mini-Hohmann
Provides rotational stability

ExoToe was developed by Surgical Design Innovations. The team at Surgical Design Innovations have extensive experience in all levels of medical device development – including product development, early design prototyping, mechanical and cadaveric testing, and early clinical use.
Prepare the PIPJ fusion site using standard surgical techniques. Make a linear dorsal incision over the proximal interphalangeal joint extending over the middle phalanx to the DIPJ. The extensor tendon is transected at the level of the PIPJ and elevated off the proximal and middle phalanges (alternatively the tendon can be left on the middle phalanx and the ExoToe implant applied over the tendon). Collateral ligaments are released at the PIPJ. Prepare the proximal and middle phalanges for fusion using surgeon preference*. The PIPJ fusion site is fixated with standard K-Wire** with or without crossing the MTPJ.
*Examples: End to end, cup and cone, “V”, etc.
**K-Wires not included
Once alignment and fixation of the toe with the K-Wire is confirmed, determine the correct size of ExoToe implant to be used. Starting with the largest sizing template (7.5), place the template onto the bone and center it over the fusion site. The sizing template clears the bone when the dorsal aspect touches the bone and the proximal and distal cuffs do not touch the bone. If the template clears the bone, continue with the next smallest size until the template does not clear the bone. Select the ExoToe implant that corresponds with the smallest template that clears the bone.
*If the smallest template (5.5) clears the bone, assess the approximation. If excessive, do not proceed with implantation of the ExoToe implant.
Middle Phalanx Fixation
Center the ExoToe implant directly over the fusion site. Dorsal to plantar digital pressure is used to push the ExoToe down onto the fusion site. The forceps are then used to crimp the tines into the middle phalanx in order to secure the ExoToe to the bone.
NOTE: Alternatively, the crimping may be completed with a curved Kelly hemostat.
Proximal Phalanx Fixation
Once the middle phalanx is crimped appropriately, the proximal portion is crimped to the proximal phalanx, making certain the ExoToe is held close to the bone with dorsal to plantar pressure during crimping. Proper fixation and engagement of the ExoToe to the bone segments is then confirmed.
NOTE: Surgeon discretion is used for removal of K-Wire. If control across the MTPJ is preferred, the K-Wire is left in place at the surgeons’ preference.
