8 The choice of treatment must be decided by individual case. More than 130 different surgical procedures have been described for its treatment. 7 There has been significant progression of the disease in HR with osteophyte formation and bony hypertrophy and there is a complete absence of motion of the first MTP joint. In cases of HL, where there is usually only a mild degree of osteophyte formation, there is generally little restriction in the range of motion available. 6 The range of motion in the joint will therefore depend on the degree of any occurring arthrosis. 1 The first MTP joint normally requires 45 to 65 degrees of dorsiflexion for adequate function of foot during ambulation. 2 developed widely accepted classification systems for HL, based on either radiographic findings and sub-chondral pathology 2 or radiographic and clinical changes. 3, 4Hallux limitus is generally acknowledged to be a precursor state, before the condition worsens and progresses to hallux rigidus. The condition is characterised by reduced or absent sagittal plane motion (usually dorsiflexion) of the hallux, with associated degenerative arthritis of the 1st MTP joint. Hallux limitus (HL) and hallux rigidus (HR) describe a painful and progressive clinical condition that affects the great toe. Keywords: Intermetatarsal, Radiographic, Osteoarthritis, Metatarsophalangeal Abbreviations The results in terms of foot function and stability did not deteriorate with time and there was little restriction in movement. At the final follow-up radiographs of both feet were taken to assess the development of osteoarthritis. Clinical re-evaluation, including examination of the foot and the completion of the Maryland Foot Score and American Orthopaedic Foot and Ankle Society questionnaire was performed on 12 patients after a mean follow-up of 14 years. Between July 1993 and June 1995, 12 patients who had undergone this procedure completed the foot and ankle outcome score survey for the subjective evaluation of symptoms. 1, 2In this paper, we have reviewed the long term outcome in terms of the clinical and radiographical results, post-operative quality of life, function of the joint and the late development of osteoarthritis. This procedure includes the treatment of hallux limitus, hallux rigidus and hallux valgus with associated degenerative joint disease. We performed a retrospective study to assess the long-term outcome of regnauld’s procedure, as originally described by Regnauld, 1 for the treatment of hallux valgus.
