OBJECTIVE The importance of spinopelvic balance and its implications for clinical outcomes after spinal arthrodesis has been reported in recent studies. However, little is known about the relationship between adjacent-segment disease (ASD) after lumbar arthrodesis and spinopelvic alignment. The purpose of this study was to clarify the relationship between spinopelvic radiographic parameters and symptomatic ASD after L4-5 single-level posterior lumbar interbody fusion (PLIF). METHODS This was a retrospective 1:5 matched case-control study...

INTRODUCTION: A goal of adult spinal deformity surgery is correction of sagittal imbalance by increasing lumbar lordosis (LL), allowing a previously retroverted pelvis to normalize as evidenced by decreases in pelvic tilt (PT). Realignment of pelvic orientation may alter the position of preexisting total hip arthroplasties (THAs). METHODS: Twenty-seven patients with unilateral THA who underwent thoracolumbar fusions for adult spinal deformity from the pelvis to L1 or above were retrospectively reviewed (levels fused, 10...

PURPOSE: Orthodontists influence dental occlusion directly. To suggest any link between dental occlusion and body posture is highly contentious, as evidenced by the literature. Rasterstereography, an optical technique that enables three-dimensional (3D) body measurements to be collected, has not yet been used to impartially examine whether different occlusal positions could instantaneously alter spine and body posture. We therefore set out to use this technique to nonsubjectively evaluate this question under static conditions...

OBJECTIVE: The scoliosis follow up is monitored by whole-spine radiographs with the Cobb angle measuring (Gold Standard). This technique is radiant, and could result from radiation-induced cancers (Ronckers et al., 2010). New monitoring methods could be needed. We have analyzed possible link between measured parameters by the optical system BIOMODTM-L, and (1) thoracic Cobb angle and (2) clinical thoracic humps (measured by scoliometer). MATERIAL/PATIENTS AND METHODS: Forty-four scoliosis patients (9 males, mean age 12...
