Article Synopsis
- - The study is a secondary data analysis of an NIH-sponsored research focusing on cost-effectiveness between surgical and non-surgical treatments for Adult Symptomatic Lumbar Scoliosis (ASLS) eight years post-enrollment.
- - Previous analyses at the five-year mark showed a cost-effectiveness ratio (ICER) of $44,033 (As-Treated) and $27,480 (Intent-to-treat), while the current eight-year data suggests that surgical treatment is more economically favorable, with an ICER of $20,569 per Quality Adjusted Life Year (QALY) gained.
- - The conclusion highlights that operative treatment for ASLS presents a more cost-effective option compared to non-operative treatment, as indicated
Article Synopsis
- The study aimed to find the best fusion levels for spinal surgery in patients with Scheuermann kyphosis by analyzing outcomes from 86 patients.
- Out of these patients, 32% developed proximal junctional kyphosis (PJK), yet there were no significant differences in preoperative characteristics between those with and without PJK.
- The research concluded that to minimize PJK and maintain better surgical results, surgeons should position the uppermost instrumented vertebra at T2 or higher, especially in cases where the C7 plumb line to sacrum distance is 50 mm or more.
Objective: The Adult Symptomatic Lumbar Scoliosis (ASLS) study is a prospective multicenter trial with randomized and observational cohorts comparing operative and nonoperative treatment for ASLS. The objective of the present study was to perform a post hoc analysis of the ASLS trial to examine factors related to failure of nonoperative treatment in ASLS.
Methods: Patients from the ASLS trial who initially received at least 6 months of nonoperative treatment were followed for up to 8 years after trial enrollment.
Mechanical complications and patient-reported outcome measures associated with high pelvic incidence and persistent pelvic retroversion: the Roussouly "false type 2" profile.

Objective: The objective of this paper was to report mechanical complications and patient-reported outcome measures (PROMs) for adult spinal deformity (ASD) patients with a Roussouly "false type 2" (FT2) profile.
Methods: ASD patients treated from 2004 to 2014 at a single center were identified. Inclusion criteria were pelvic incidence ≥ 60° and a minimum 2-year follow-up.
Objective: Previous reports of rod fracture (RF) in adult spinal deformity are limited by heterogeneous cohorts, low follow-up rates, and relatively short follow-up durations. Since the majority of RFs present > 2 years after surgery, true occurrence and revision rates remain unclear. The objectives of this study were to better understand the risk factors for RF and assess its occurrence and revision rates following primary thoracolumbar fusions to the sacrum/pelvis for adult symptomatic lumbar scoliosis (ASLS) in a prospective series with long-term follow-up.
