Abstract
1. The etiology of hallux rigidus has been studied by an examination of ten adolescent and four adult patients.
2. Although osteochondritis dissecans of the metatarsal head has been seen in two cases, our evidence generally suggests that metatarsus primus elevatus is the important etiological factor in established hallux rigidus.
3. The common factor for the production of symptoms is the limitation of dorsiflexion of the first metatarso-phalangeal joint, just as the key to treatment is the existence of a good range of plantar-flexion of the joint.
4. The technique and results of the operation of phalangeal extension osteotomy for hallux rigidus are given.
