Abstract

We treated 45 hips with idiopathic necrosis of the femoral head stages I–III with core decompression. Average age of patients was 41 (27–68) years and average follow-up 68.9 (31–120) months. In 30 hip joints in stage I, 29 showed no radiographic progression and a complete remission of the changes consistent with necrosis on MRI at the last follow-up. In 27 patients the clinical result – based on the Harris Hip Score (HHS) assessment – was excellent (average HHS 91.9 points). Of nine hips in stage II, four had received a total hip arthroplasty, one had deteriorated to stage IV, and four were still classified as stage II (average HHS 95 points). Of six hips in stage III, three had received a total hip arthroplasty and three had deteriorated to stage IV (average HHS 73 points).

Résumé

Nous avons traité 45 hanches présentant une nécrose idiopathique de la tête fémorale de stade I–III par décompression . L'âge moyen des malades était de 41 (27–68) ans et le temps moyen de suivi de 68,9 (31–120) mois. Pour 30 hanches de stade I, 29 n'ont montré aucune progression radiographique au dernier recul et une complète regressiondes des anomalies IRM. Chez 27 malades le résultat clinique était excellent (HHS moyen 91,9 points). De neuf hanches au stade II,quatre avait reçu une arthroplastie totale, une s'était aggravée au stade IV et quatre étaient encore classées comme stade II (HHS moyen 95 points). De six hanches au stade III, trois avait reçu une arthroplastie totale et trois s'étaient aggraveés au stade IV (HHS moyen 73 points).
