Why the Hips Remain Stable When the Spine Strays: A Deeper Analysis of the Relationship Between Hip Displacement and Severe Scoliosis in Patients With Cerebral Palsy.

Matthew J Hadad, Amy L Xu, Barry R Bryant, Nicholas S Andrade, Alexander H Hoon, Paul D Sponseller,

<h4>Background</h4>Many patients with spastic quadriplegic cerebral palsy (CP) and severe scoliosis develop hip displacement, whereas others do not. We investigated demographic characteristics, risk factors for CP, and imaging findings associated with nondisplaced hips in patients with CP and severe scoliosis.<h4>Methods</h4>We retrospectively analyzed records of 229 patients with spastic quadriplegic CP ...

Changes in patients' depression and anxiety associated with changes in patient-reported outcomes after spine surgery.

Rafa Rahman, Alvaro Ibaseta, Jay S Reidler, Nicholas S Andrade, Richard L Skolasky, Lee H Riley, David B Cohen, Daniel M Sciubba, Khaled M Kebaish, Brian J Neuman,

OBJECTIVE:The authors conducted a study to analyze associations between changes in depression/anxiety before and 12 months after spine surgery, as well as changes in scores using the Patient-Reported Outcomes Measurement Information System (PROMIS) at the same time points. METHODS:Preoperatively and 12 months postoperatively, the authors assessed PROMIS scores for depression, ... Read more >>

Crossing the Cervicothoracic Junction in Cervical Arthrodesis Results in Lower Rates of Adjacent Segment Disease Without Affecting Operative Risks or Patient-Reported Outcomes.

Alvaro Ibaseta, Rafa Rahman, Nicholas S Andrade, Akachimere C Uzosike, Venkata K Byrapogu, Alim F Ramji, Richard L Skolasky, Jay S Reidler, Khaled M Kebaish, Lee H Riley, Daniel M Sciubba, David B Cohen, Brian J Neuman,

STUDY DESIGN:Retrospective cohort study. OBJECTIVE:To evaluate the risks and benefits of crossing the cervicothoracic junction (CTJ) in cervical arthrodesis. SUMMARY OF BACKGROUND DATA:Whether the CTJ should be crossed in cervical arthrodesis remains up for debate. Keeping C7 as the distal end of the fusion risks adjacent segment disease (ASD) and ...

Systematic review of observational studies reveals no association between low back pain and lumbar spondylolysis with or without isthmic spondylolisthesis.

Nicholas S Andrade, Carol M Ashton, Nelda P Wray, Curtis Brown, Viktor Bartanusz,

<h4>Purpose</h4>The hypothesis that spondylolysis (SL) and/or isthmic spondylolisthesis (IS) cause low back pain (LBP) is widely accepted representing surgical indication in symptomatic cases. If SL/IS cause LBP, individuals with these conditions should be more prone to LBP than those without SL/IS. Therefore, the goal of the study was to assess ... Read more >>

Twenty-year perspective of randomized controlled trials for surgery of chronic nonspecific low back pain: citation bias and tangential knowledge.

Nicholas S Andrade, John P Flynn, Viktor Bartanusz,

<h4>Background context</h4>After decades of clinical research, the role of surgery for chronic nonspecific low back pain (CNLBP) remains equivocal. Despite significant intellectual, human, and economic investments into randomized controlled trials (RCTs) in the past two decades, the role of surgery in the treatment for CNLBP has not been clarified.<h4>Purpose</h4>To delineate ...
