ABSTRACT

The purpose of this study is to describe the outcome of total hip arthroplasty for management of aseptic osteonecrosis of the femoral head due to sickle cell disease. This consecutive series carried out over a 7-year period in 38 patients with a sickle-cell anaemia includes a total of 48 cemented prosthesis. The mean follow-up period was 5 years. Arthroplasty restored normal hip function (PMA score = 18) in 64% of cases. In 32% of cases the PMA score was more than 15. Pain was greatly reduced with total relief being achieved in 94% of cases. Walking ability also improved with 85% of patients having an unlimited walking distance. Radiological examination demonstrated edging on 36% of cupulas and 29% of the shafts. Complications were observed in 19% of cases. The main complications were loosening and dislocation of the prosthesis. Although the complication rate was high, functional outcomes in this series were good. These findings indicate that arthroplasty should be considered as the treatment of choice for aseptic osteonecrosis due to stage 3 and 4 sickle-cell disease in young patients. Use of uncemented implant and type of frictional torque are discussed.

ABSTRACT

Trente-huit patients drepanocytaires presentant une osteonecrose aseptique de la tete femorale ont beneficie d'une arthroplastie totale de la hanche sur une periode de 7 ans; soit une serie consecutive de 48 protheses cimentees. Avec un recul moyen de 5 ans; l'arthroplastie a permis d'obtenir dans 64des cas une fonction normale (score PMA = 18); et dans 32des cas un PMA superieur a 15. Le gain sur la douleur etait tres important puisque l'indolence a ete obtenue dans plus de 94des cas; de meme que sur la marche car 85des patients n'avaient pas de limitation du perimetre de marche. Sur le plan radiologique; 36des cupules et 29des tiges presentaient des liseres. Les complications ont ete retrouvees chez 19des patients; dominees par les descellements et les luxations. Les resultats fonctionnels obtenus dans la serie; avec un taux de complication important mais qui reste inferieur a ceux deja publies dans la litterature pour cette pathologie; incitent a retenir l'arthroplastie comme traitement de choix de l'osteonecrose aseptique du drepanocytaire au stade 3 et 4 du sujet jeune. Ils amenent a discuter le choix de l'implant; et du couple de frottement
