Summary
Five cases of fracture of the lateral tibial condyle of the split-depression type were treated by elevation of the depressed fragment, bone grafting and cancellous bone screws. During the operation, tantalum markers were inserted into the depressed fragment and the tibial metaphysis for radiographic stereophotogrammetric analysis. Postoperatively a plaster cast was applied for one month and weightbearing was not allowed for 3 months. In three cases, a depression of the elevated fragment, at the most 2.8 mm, recurred during the first month after operation. This was not considered to be significant and more aggressive postoperative mobilisation may be warranted.
Résumé
Cinq cas de fracture par enfoncement du plateau tibial externe ont été traités par relévement du fragment impacté, greffe osseuse et vis à spongieux. Au cours de l'intervention des marqueurs au tantale ont été placés dans le fragment enfoncé et dans la métaphyse tibiale pour analyse stéreophotogramétrique. En post-opératoire un plâtre a été maintenu pendant un mois et l'appui n'a été autorisé qu'à la fin du troisième mois. Une récidive de l'enfoncement du fragment relevé (2.8 mm au maximum) est survenue dans trois cas, durant le premier mois post-opératoire. Les auteurs concluent que la mise en décharge post-opératoire n'est pas indispensable et qu'une mobilistion précoce plus active pourrait être envisagée.
