Surgical treatment of scoliosis in patients with osteogenesis imperfecta: a single institution case series.

Background: Osteogenesis imperfecta (OI) is a connective tissue disorder characterized by skeletal deformities, bone fragility, and spinal complications. Various studies' insights underscored the impact of scoliosis on pulmonary function, positive outcomes with spinal fusion, and improved functional abilities post-surgery. However, partial loss of correction remains inevitable.

Methods: This study examines six surgically treated OI patients with scoliosis. Surgical intervention using a posterior approach with pedicle screws and hooks aimed to correct spinal deformities. Preoperative, postoperative, and follow-up radiological assessments were conducted, revealing significant reductions in scoliotic angles post-surgery.

Results: Complications included infections and proximal junctional kyphosis requiring revision surgeries. Despite the challenges posed by poor bone quality and implant stability, no implant failures occurred in this series. Ponte osteotomies at the apex of deformity aided in corrective maneuvers.

Conclusion: Surgical treatment of scoliosis in patients affected by OI is challenging and may be associated with perioperative and postoperative complications. Ponte osteotomy may improve the correction and reduce necessary force at the time of correction.
