Abstract

This case study describes the micromorphology and some biochemical features of gluteus medius muscle in a 79yearold woman with radiographic signs of coxarthrosis but with no clinical symptoms who initially was admitted in the orthopaedic emergency service with a nondisplaced subcapital fracture of the femoral neck due to a domestic accident fall The Xray of the hip showed some characteristic features of coxarthrosis classified grade 2 of the Kellgren criteria After informed consent it was decided to carry out the functional evaluation according to the indexes of Lequesne and WOMAC Western Ontario and McMaster Universities Osteoarthritis Index and to take a biopsy of the gluteus medius muscle for microscopical examination and myosin heavy chain isoform identification during hip replacement surgery For the Lequesne Index score 0–24 the total score was 0 and for the WOMAC score 0–96 the total score was also 0 both speaking in favour of full joint and muscle function All the structural features observed in muscle were considered not to have any pathological relevance The composition of the myosin heavy chains in the gluteus medius muscle was 48 MHC I 41 MHC IIa and 11 MHC IIx The muscle characteristics do not support earlier concepts about muscle weakness as a predisposing factor for osteoarthritis It is moreover concluded that the diagnosis should rather consider clinical symptoms than radiographic signs of osteoarthritisCette étude de cas décrit la micromorphologie et quelques caractéristiques biochimiques du muscle gluteus medius moyen fessier chez une patiente âgée de 79 ans avec des signes radiographiques de coxarthrose mais sans symptomatologie qui avait été admise dans le service d’urgence avec une fracture souscapitale alignée du col du fémur à la suite d’un accident domestique chute La radiographie de la hanche montrait quelques signes de coxarthrose degré 2 de Kellgren Après information et acceptation de la patiente on a effectué en utilisant les Index de Lequesne et WOMAC l’évaluation fonctionnelle ainsi qu’une biopsie du muscle gluteus medius pendant l’intervention chirurgicale pour examen microscopique et identification des isomorphes de la chaîne lourde de myosine Pour l’Index de Lequesne score 0–24 le total a été 0 et pour celui de WOMAC score 0–96 le score total a aussi été zéro les deux indices étant favorables à une bonne fonctionnalité musculaire et articulaire Toutes les caractéristiques structurales observées ont été considérées sans relevance pathologique La composition des chaînes lourdes de myosine dans le muscle gluteus medius a été de 48 MHC I 41 MHC II et 11 MHC IIx Les caractéristiques du muscle n’appuient pas l’hypothèse que la dysfonction musculaire serait un facteur qui prédisposerait à l’arthrose On a conclut également que le diagnostic de coxarthrose doit plus prendre en compte les symptômes cliniques plutôt que les signes radiographiques d’arthrose
