Symptomatic flexion deformity of proximal interpahalangeal joint (PIPJ) is one of the most common foot deformities and usually treated with arthrodesis. In general, percutaneous K-wires are used to stabilize the joint after excision of cartilage. K-wires projecting out of the toe need special care and can occasionally be dislodged accidentally. Furthermore issues such as cellulitis, pin tract infections, rarely osteomyelitis and need for removal make alternative fixation methods desirable. Smart toe is an intra-osseous titanium memory implant, which is stored frozen. It expands on insertion and does not require removal. 30 consecutive K-wire PIPJ arthrodesis were compared with 30 Smart toe PIP fusions with a mean follow up of 6 months. Post operative forefoot scores and complications were documented.Background
Methods
The patients were retrospectively assessed with a case note review and an updated clinical evaluation. The assessment focussed particularly on wound complications including breakdown classified as either major or minor, and association with infection, haematoma and drainage. Neurological symptoms were also noted.
Forty-five procedures were carried out over a 10-year period. The patients were retrospectively assessed with a case note review, and an updated clinical evaluation. The assessment focussed on pain, stability and impact on daily living.
