AbstractWe used biodegradable poly-l-lactide screws in rotational acetabular osteotomy in 41 hips of 41 patients, and studied the complications after an average follow-up of 4.9 years (range 1.07.7 years). There were 39 females and 2 males, their average age at the time of the operation was 32 years (range 1255 years). A small subcutaneous abscess appeared around the non-absorbable sutures in 2 patients after surgery. There was 1 case of thrombophlebitis and 1 of local dermatitis. The small subcutaneous abscess resolved after the removal of the suture material in the 2 cases, and the thrombophlebitis resolved with aspirin. The local dermatitis persisted but was cured by local steroid therapy over 5.8 years. The incidence of local dermatitis after the use of biodegradable implants should be further investigated.
Rsum Nous avons utilis des vis biodgradables en poly L lactide pour les osttomies actabulaires rotatoires des 41 hanches de 41 patients et nous avons tudi les complications possibles sur un suivi moyen de 4.9 ans (de 1 7.7 ans). Lchantillon comportait 39 femmes et 2 hommes. Lge moyen au moment de lopration tait de 32 ans (12 55 ans). Nous avons not 2 cas de complication post-opratoire sous la forme dun petit abcs sous-cutan autour des sutures irrsorbables, 1 cas de thrombophlbite et 1 cas deczma local. Le petit abcs souscutan sest rsorb aprs enlvement du matriau de suture dans les 2 cas, la thrombophlbite a t traite laspirine et leczma local a t soign par une thrapie locale aux stroides en 5.8 ans. La frquence des dermatites locales aprs lutilisation des implants biodgradables devrait tre tudie sur un plus grand nombre de cas.
