Selective hemivertebrae resection in congenital scoliosis with multiple hemivertebrae

There are no established guidelines regarding the surgical strategy to be adopted in congenital scoliosis with multiple hemivertebrae-decision has to be guided taking into account the contribution of each hemivertebra to the deformity and its growth potential. We describe a case of a 12-year-old woman with congenital scoliosis due to unbalanced multiple hemivertebrae. Preoperative imaging revealed the presence of three hemivertebrae-at D7, D10 and L5. Our surgical strategy was guided by various factors-the morphology of the hemivertebrae, the location, the contribution of each hemivertebra to the deformity and their relationship to each other. Based on this, we performed a selective hemivertebrae resection-completely resecting L5 hemivertebra and performing 'egg-shell' decancellation of D7 hemivertebra and in situ fusion of D10 hemivertebra, yielding satisfactory results. This case report illustrates a rational thought process that can guide a paediatric spinal deformity surgeon in treating scoliosis with multiple hemivertebrae.
