Arthrodesis of the 1st metatarso-phalangeal joint (MTPJ) is a common procedure in forefoot surgery for hallux rigidus and severe hallux valgus. Debate persists on two issues - the best preparation method for the articular surfaces, and the optimal technique for operative stabilisation of the joint. We performed 1st MTPJ arthrodesis in 100 patients randomized into two equal groups. In the first group, the articular surfaces were prepared using cup-and-cone reamers, whilst in the second group, ‘flat cut’ osteotomies were performed with an oscillating saw. In all other respects, their treatment was identical. Fixation was secured using a plantar double compression Fixos™ screw and dorsal Anchorage™ plate. Full weight-bearing was allowed on the first post-operative day. Patients completed self-administered satisfaction questionnaires, including an AOFAS and SF-36 score pre-operatively and at two and six months post-operatively. Clinical examination and radiographs were compared at zero, two and six months. Statistical analysis was performed using Instat.Introduction
