The hallux rigidus, first described by Nicoladoni in 1881 (1), is the painful and decreased motion, especially dorsiflexion at the metatarsophalangeal joint, of the great toe. The purposes of this report were to evaluate the mid-term results of the Sliding osteotomy technique(2,3,4).

Thirty nine (46 feet) consecutive patients (mean age 38 years) with hallux rigidus of I and II grade were followed over a five-year period.

All patients were evaluated clinically and radiographically preoperatively and post operatively.

At the time of final follow-up, the mean AOFAS score was significantly improved: excellent 26 (56,5%); good 12 (26%); fair 6 (13%); poor 2 (4,5%).

This clinical review suggest that this procedure as a safe, effective measure to treat in patients with hallux rigidus of I and II grade.
