Operative intervention of unstable paediatric pelvic fracture: radiological and functional assessment.

Abstract

The aim of the study was to add to the literature new data regarding the evaluation of surgical fixation of challenging unstable paediatric pelvic fractures, radiologically and clinically besides recording any complications through the follow-up period. Prospective study was conducted at our hospital between 2012 and 2017 where 21 patients less than 16years with unstable fracture pelvis were surgically fixed. The method of fixation varied between the external percutaneous fixation and internal fixation. The Infix system was used in for anterior ring fixation in some cases. Patients were evaluated radiologically and functionally using the functional independence measure questionnaire (FIM) and the modified Merle d'Aubigne and Postel (MDP) score. Twelve males and 9 females were fixed with mean age of 12.5years. Motorcar accident was the main mode of trauma. Nine patients had fracture pelvis Tile's type B and 12 had Tile's type C injuries. All fractures united by 8weeks. No patients suffered from pelvic asymmetry or leg length discrepancy at a mean follow-up of 2years. The mean of FIM was 122.5 and the mean of MDP score was 16.2. Displaced unstable pelvic fractures in children need a systematic evaluation of the injury pattern. These serious fractures should be referred for anterior ± posterior ring stabilization. Promising clinical outcomes with surgical fixation can be reached with a low rate of complications. Further large-scale studies should be conducted for the calling literature.
