Spine deformity

The purpose of this study was to assess L4-S1 inter-vertebral coronal motion of the unfused distal segments of the spine in patients with adolescent idiopathic scoliosis (AIS) after instrumented fusion with regards to postoperative time and fusion length, independently. ⋯ Motion in the unfused distal lumbar segments did not vary within the >10-year follow-up period. However, in patients with a primary thoracic curve and a nonstructural lumbar curve, the choice to fuse longer versus shorter may have significant consequences. The summed motion from L4 to S1 is 50% greater in patients fused longer compared with those patients with a selective fusion, in which postoperative motion is shared by more unfused segments. The implications of this focal increased motion are unknown, and further research is warranted but can be surmised.

Observational Study. ⋯ In one of the first studies evaluating the publication rate of podium presentation from the SRS and IMAST annual meetings, we found an overall publication rate of 44.37% (47.83% SRS, 41.53% IMAST) and 63.64% for award-nominated papers.
