PURPOSE OF THE STUDY: @entity2096 ( @entity2096 ) is a rare and @entity85 . The results and complications of surgical correction of this deformity using ring fixators (Ilizarov/ @entity2414 ) have been evaluated. MATERIAL AND METHODS: We retrospectively reviewed a consecutive series of 30 @entity1 with @entity2096 , between the ages of 3.3 and 17 years (mean, 9.3 years), with 35 lengthening procedures. Ten cases were treated with an Ilizarov frame, 25 cases with a @entity2414 ( @entity2414 ). RESULTS: The average lengthening at femoral osteotomy was 44.3 mm. Nine @entity1 underwent an additional tibial lengthening by an average of 24.2 mm. The total lengthening was 50.5 mm (28-85 mm). A @entity174 after removal of the fixator occurred in 25.7% of the cases, and a pin-site infection with the subsequent need of operative revision was found in 8.5%. A subluxation of the knee joint was observed in 11.4% and a persistent limitation of the knee joint range of motion in 22.8%. CONCLUSIONS: Despite several complications, the use of ring fixators, especially the @entity2414 , is an effective method for treatment of this @entity85 . The complication rate was similar with the use of either ring fixator. Some complications can be decreased with experience. The risk of @entity3031 can be reduced by joint bridging and @entity174 after frame removal can be avoided by prophylactic rodding.
