RESUMO
Hallux rigidus refers to limitation of motion of the metatarsophalangeal joint of the great toe. For patient who had diffuse osteoarthrosis of the first metatarso-phalangeal joint, arthrodesis is a reasonable alternative if non-operative measures fail. In the current series, 25 feet grade III and IV hallux rigidus were treated by arthrodesis of the first metatarso-phalangeal joint using a low profile miniplate and screws. After an average follow up period of 22 months, clinical examination showed good cosmetic and functional results in most of cases. Of the 25 feet, 23 [92%] had less or no pain postoperatively. Good radiological union was observed in 23 feet at a mean of 7 weeks. The complications were infrequent; mainly non- union in 2 feet [8%]. This study concludes that patients of advanced grades of hallux rigid- us with significant pain, limitation of joint motion, marked loss of articular cartilage, and osteophytes formation are best treated by arthrodesis of the metatarsophalangeal joint using rniniplate for fixation
