Outcome and Prognosis
The experiences of other authors indicate that complete correction of the toe is necessary to achieve the best result. Of course, this presumes careful attention to detail and a toe with normal vascularity. Taylor18,19 and Pyper,23 via transfer of both the long and short flexor to the extensor hood without bony resection, achieved only 72% and 51% good results, respectively. Pyper also noted that with soft-tissue procedures alone, the deformity recurred and results were somewhat unpredictable. Therefore, Frank and Johnson24 and McCluskey et al25 recommend PIP resection along with soft tissue procedures to realign the toe.
Barbari and Brevig26 reviewed 31 patients who had surgery on multiple toes. These authors concluded that the best cosmetic results were achieved in younger patients, and they noted that active or passive motion in the interphalangeal joints was present in 60% of these cases. Of course, restriction in range of motion is an intended outcome of the procedure. Patients must be aware that in most instances, they will sacrifice prehensile action of the toe for less pain, will have better shoe-wearing capabilities, and, ideally, will have an improved cosmetic result. Specific disease entities seem to fare similarly; Cyphers and Feiwell27 reported 60% good results in patients with myelomeningocele.
Future and Controversies
A future prospective study that separates claw toes from hammer toes, fixed from flexible, severe from mild, and bony correction (ie, PIP and metatarsal neck osteotomies) from soft-tissue procedures alone is necessary. The addition of an extensor tendon transfer beneath the intermetatarsal ligament with reattachment to the proximal phalanx may help improve continued deformity at the time of surgery or recurrent postoperative dorsiflexion deformity.
When to perform each of the procedures on a claw toe and the extent of the surgical procedure on a single toe remain controversial. Other controversies are a bolster suture above the PIP joint in lieu of a pin, the size of the toe fixation pin, the duration it needs to remain in place, and whether or not it needs to cross the MTP joint.
