Abstract
Purpose: Managing severe scoliosis is challenging and risky with a significant complication rate regardless of treatment strategy. In this retrospective comparative study, we report our results using a three-rod compared to two-rod construct in the surgical treatment of severe spine deformities to investigate which technique is safer, and which provides superior radiological outcomes.
Methods: Forty-six consecutive patients undergoing posterior spine fusion for scoliosis between 2006 and 2017 were identified in our institutional records. Inclusion criteria were minimum coronal deformity of 90°, age < 18 years at the time of surgery and a minimum 2 years of follow-up. Radiographic and clinical parameters, as well as post-operative complications were compared between the two groups.
Results: There were 21 patients in the three-rod group and 25 in the two-rod group. The mean preoperative major coronal deformity was 100°± 9 and 102°± 10 in the three-rod and two-rod, respectively (p = 0.6). The average major curve correction was 51% and 59% in three-rod and two-rod groups, respectively (p = 0.03). The post-operative thoracic kyphosis was 30°± 11 and 21°± 12 in the three-rod and the two-rod groups, respectively (p = 0.01). The surgical time was 476 ± 52 and 387 ± 84 min in three-rod and two-rod, respectively (p < 0.01). One patient in the two-rod cohort showed permanent post-operative sensory deficit. There were three unplanned returns to operating theater in the two-rod group.
Conclusions: Coronal correction was better with two-rod, whereas sagittal balance was superior with three-rod. Both techniques achieved balanced spine treating severe scoliosis. The two-rod technique was associated with a higher likelihood of requiring revision surgery.

Aims & Scope
The Journal of Children’s Orthopaedics is the official journal of the European Paediatric Orthopaedic Society (EPOS) and is published by The British Editorial Society of Bone & Joint Surgery.
It provides a forum for the advancement of the knowledge and education in paediatric orthopaedics and traumatology across geographical borders. It advocates an increased worldwide involvement in preventing and treating musculoskeletal diseases in children and adolescents.
The journal publishes high quality, peer-reviewed articles that focus on clinical practice, diagnosis and treatment of disorders unique to paediatric orthopaedics, as well as on basic and applied research. It aims to help physicians stay abreast of the latest and ever-changing developments in the field of paediatric orthopaedics and traumatology.
The journal welcomes original contributions submitted exclusively for review to the journal. This continuously published online journal is fully open access and will publish one print issue each year to coincide with the EPOS Annual Congress, featuring the meeting’s abstracts.
