[Osteoarthrosis of the first metatarso-phalangeal joint. Surgical treatment; 92 cases]

The study of 92 cases of osteoarthrosis of the first metatarso-phalangeal joint (or hallux rigidus) shows the importance of two aetiological factors : excessive length of the first metatarsal in the so-called primitive osteoarthrosis, and traumatism for the secondary forms. The results of arthrodesis are rather better than these of arthroplasty and exostosectomy, mainly in men after 50 years.
