Summary
Primary uncemented Porous-Coated Anatomic total hip replacement was carried out in 72 hips in 62 Chinese patients. Their average age was 50 years and the average follow up was 3 1/2 years. The most common diagnosis was avascular necrosis. The average preoperative Harris score of 36.3 points improved to 83.2 at the last follow up. The pain score improved from 13.7 out of 44 to an average of 42. Seven of 8 hips with thigh pain had an inadequately fitting stem which had subsided. Only one cup was revised because of a technical error and one femoral component for loosening. Uncemented Porous-Coated Anatomic total hip replacement gave good early results in Chinese patients.
Résumé
Soixante-douze hanches chez 62 patients chinois ont été remplacés par des prothèses totale de hanche PCA non cimentées. L'âge moyen des patients était de 50 ans. Le diagnostic le plus fréquent était la nécrose avasculaire. Le suivi moyen était de 3 ans 1/2. Le score pré-opératoire selon Harris était de 36.3 et s'était amélioré à 83.2 lors du dernier contrôle. L'amélioration de la douleur était très bonne. Le score pré-opératoire moyen de la douleur qui était en moyenne de 13,7 pour 44 patients, est passé à une moyenne de 42 lors du dernier suivi. Sept sur 8 hanches avec douleur de cuisse ont eu une pose inadéquate de la tige de prothèse qui montra un certain degré d'enfoncement. La pose inadéquate et l'enfoncement de la tige semblèrent être les causes essentielles contribuant à des douleurs de cuisse. Une planification pré-opératoire signeuse est essentielle pour obtenir une bonne mise en place de la tige. Une seule cupule a été révisée en raison d'une erreur technique et une tige fut reprise en raison du descellement. La prothèse de hanche PCA sans ciment a donné de bons résultats précoces chez les patients chinois.
