Current And Emerging Insights On Hammertoe Correction
Case Study Two: When There Is Post-Op Drift Of The Second Toe At The Proximal Interphalangeal Joint
A 46-year-old female previously had hammertoe correction via a condylectomy of the second proximal interphalangeal joint with percutaneous K-wire fixation. The initial procedure and postoperative course were unremarkable. Protected weightbearing occurred until K-wire removal at six weeks postoperatively. Gradually over a three-month period, the patient noted a drift of the second toe at the proximal interphalangeal joint laterally toward the third toe. The surgeon attempted conservative care but this ultimately failed to realign the toe.
Typically, pseudofibrosis at the arthroplasy site maintains stabilization of the toe following K-wire removal but this was not the case for this patient. In this case, with mobilization of the fibrosis, the toe destabilized at the proximal interphalangeal joint and a valgus deformity occurred. Surgical options included a repeat K-wire stabilization, a trans-distal interphalangeal/proximal interphalangeal screw or an intramedullary device. In this case, use of the Pro-Toe salvaged and stabilized the proximal interphalangeal joint deformity.
As technology drives the world of foot and ankle surgery, there will be many more devices developed for the correction of digital deformity. Each of the aforementioned devices has its own pros and cons. However, the most important aspect in hammertoe correction is selecting the appropriate implant for each individual patient. Different implant usage will also vary according to the comfort level of the surgeon. As we proceed forward in practice, the role of K-wire fixation has decreased due to the obvious apparent risks these wires carry. However, K-wires do and always will have an appropriate place in the foot and ankle surgeon’s armamentarium for digital correction.
When we consider the evolution occurring with hammertoe correction and surgical implants, it is important to be comfortable with multiple devices and techniques. As with any surgical procedure, one must tailor implant selection to each patient’s specific individual anatomic constraints. Simply said, there may not be one hammertoe implant or fixation that covers every patient.
