Abstract:
INTRODUCTION Limitation of movement in the sagittal plane and pain in the first metatarsophalangeal joint was named 'hallux flexus' for the first time in 1887 by Davies-Colley. In 1888 Cotterill was the first to use the term 'hallux rigidus' to describe this condition. After hallux valgus, hallux rigidus is the disease that most commonly affects the first metatarsophalangeal joint, and can be more disabling for the patient.More than 100 years after this initial description, the debate on the etiology of this disease remains open. OBJECTIVESOur objective is to specify, by means of a scientific methodology, the anatomical variations that influence the pathogenesis of hallux rigidus. MATERIAL AND METHODSA retrospective study of cases and controls was performed.The cases were a series of patients afflicted with hallux rigidus operated on in several centres (Hospital Universitari de Tarragona Joan XXIII, Hospital Comarcal de Mora d'Ebre, Hospital de San Rafael and Hospital de Sant Pau i Santa Tecla). Out of a total 248 cases of hallux rigidus examined, 132 were chosen, the remainder being ruled out for various reasons. A control group with clinically and radiologically normal feet was established. Both groups were comparable in terms of side, sex and age.The following variables were studied:A- Clinical and Morphological Variables: 9 variables were collected from each foot. B- Radiological Measurements: 14 weight-bearing dorsoplantar projection measurements and 7 weight-bearing lateral projection measurements were taken of each foot. The statistical methodology included a descriptive analysis, univariable analysis, an analysis of measurement accuracy and a multivariable analysis.RESULTSA comparative statistical analysis of the resulting measurements between the group of pat
