Arthrodesis of the toe joints with an intramedullary cannulated screw for correction of hammertoe deformity.
Twenty-four patients (37 feet, 51 toes) affected by hammertoe deformity of the lesser toes and treated surgically by arthrodesis of the proximal interphalangeal joint, stabilized with an intramedullary titanium cannulated screw, were reviewed 1-4 years after the operation. At follow-up, the arthrodesis was fused in 48 toes; three toes showed an asymptomatic radiographic nonunion, and in one of them the screw was broken. In seven toes, the cannulated screw was removed because of persistent pain at the tip of the toe where the head of the screw was located. In one case only, there was a late infection, with toe malalignment. All the patients were able to use street shoes 2 weeks after surgery. The average AOFAS score at follow-up was 86.54 points. Compared to the conventional temporary stabilization with an intramedullary Kirschner wire, the stabilization with a cannulated screw decreases the risk of infection, of radiographic nonunion, and of mallet toe deformity.
