[Surgical treatment of congenital scoliosis].

objectiveEarly correction of congenital scoliosis including short fusion, while minimizing both mobility restrictions and growth impairment. INDICATIONS: Congenital scoliosis with marked deformity, proven progression, significant compensatory curves, and/or impairment of trunk balance. Furthermore, in case of compression of neural structures or pain due to secondary degeneration. CONTRAINDICATIONS: No absolute contraindication. SURGICAL TECHNIQUE: Posterior approach to the apex of the deformity. In the growing spine the periosteum should only be touched at the levels where fusion is planned. Insertion of pedicle screws adjacent to the hemivertebra. The posterior elements of the hemivertebra are removed: lamina, joint facets, pedicle, transverse process. Resection of the accessory proximal rib in the thoracic spine. Following blunt dissection at the lateral and anterior surface of the hemivertebra, the body of the hemivertebra and the adjacent discs are resected. The resulting gap is closed by compression via transpedicular instrumentation thus correcting the scoliotic deformity. In case of synostosis or contralateral bar formation, the concave side of the spine is dissected and the synostosis osteomized. POSTOPERATIVE MANAGEMENT: Early mobilization on postoperative day 1. Bracing for 12 weeks depending on stability of the instrumentation. Periodic clinical and radiographic controls until the end of growth.

resultsPosterior hemivertebra resection with transpedicular instrumentation is considered as the standard treatment of congenital scoliosis. Correction rates of 60-80% are achieved. Cervical and lumbosacral hemivertebrae may require an additional anterior approach. In case of synostosis, bar formation, or rib synostosis, further corrective surgeries may be necessary during growth.
