The treatment of femoral fractures in children with cerebral palsy.

OBJECTIVE

The purpose of this study is to retrospectively evaluate a group of children affected by cerebral palsy with a recent femoral fracture, and to analyse the results and complications in relation to the treatment used.

MATERIALS AND

METHODS

The analysis was performed on 36 children (21 M, 15 F, 8-14 years old) with cerebral palsy (7 diplegia, 28 tetraparesis, 1 hemiplegia) with a metaphyseal or a diaphyseal femoral fracture. The patients were subdivided into two groups according to their Gross Motor Function Classification System (GMFCS) level: level 2-3 (9 patients) and level 4-5 (27 patients), evaluating the presence of complications and malunions for each group at the end of each follow up.

RESULTS

The fractures were displaced in 24 patients and nondisplaced in 12 patients. In 26 cases the treatment involved a closed reduction and immobilisation in a long leg hip spica cast for 7 weeks, while in 10 cases the treatment involved an open reduction-internal fixation (ORIF) followed by a 3-week period in a plaster coated fracture bandage.

CONCLUSIONS

Taking into consideration the maximum possible recovery of function, an ORIF is preferable to prevent malunion, particularly in distal metaphysis and distal shaft fractures. In the GMFCS level 2-3 patients, surgery has allowed to recover, or at least maintain, the pre-fracture functional level, while in patients with GMFCS level 4-5, it has allowed to reduce the immobilisation times and prevent the development of decubitus lesions.
