Updates on preoperative planning, limb deformity analysis and surgical correction for the growing children: EPOS Meeting Marseille 2015 proceedings

Successful deformity correction depends on establishing the aetiology of the deformity. Clinical examination, additional laboratory tests and consultation with other experts may be needed to complete the workup. Imaging studies should include full-length standing X-rays in all relevant planes, and additional imaging modalities like computed tomography (CT) and magnetic resonance imaging (MRI) may add information on bone morphology and growth plates’ anatomy. Based on the data, analysis of the deformity and length differences is performed, followed by prediction of deformities at skeletal maturity. The patients need to be followed up on a regular basis and repeat analysis should be done to improve the accuracy of prediction for final limb length difference. Limb deformity and lengthening correction plans are drawn and updated during follow-up, to achieve straight and equal lower limbs at maturity. Timely surgical procedures are performed using appropriate techniques and the most modern technologies available. These principles are discussed and demonstrated with case examples.
