Proximal functional kyphosis (PJK) is a common complication (26-39%) following multilevel instrumented fusion for spinal deformities. It is defined as a focal segmental kyphosis of more than 10 degrees between upper instrumented vertebra (UIV) and 2 levels cranial to UIV (UIV+2); and a focal increase in kyphosis of more than 10 degrees between UIV and UIV+2 [1]. Although the clinical impact of ...

Study Design: This is a retrospective cohort study using data from the adult spinal deformity (ASD) database of single institution. Purpose: To investigate incidence proximal junctional failure and distal (DJF) after ASD surgery with lower instrumented vertebra (LIV) at L5. Overview Literature: Spinopelvic fixation thoracic to pelvis current gold standard treatment for ASD. However, LIV L5 acce...

STUDY DESIGN Retrospective review of a prospectively collected pediatric orthopedic spine database. OBJECTIVE To investigate whether pelvic incidence (PI) changes during growing rod treatment and to report the effects of PI, if any, on complications during treatment. SUMMARY OF BACKGROUND DATA Growing rods have been demonstrated to correct spinal deformity in early onset scoliosis while all...

Background: The purpose of this study was to use magnetic resonance imaging (MRI)-based assessments of multifidus muscle to predict development of proximal junctional kyphosis (PJK). Methods: We retrospectively reviewed 62 patients with lumbar degenerative disease (LDD) who underwent fusion of L5 and all the upper instrumented vertebrae (UIVs) in the thoracolumbar spine (T9-L2), with ≥2 years’ ...

Magnetically controlled growing rods (MCGR) allow more frequent outpatient lengthenings to better mimic the physiological growth. The assessment of distractions with radiographs raised concerns regarding ionizing radiation exposure in children. aim was assess necessity after every lengthening MCGR. A retrospective analysis 30 consecutive patients (19F, 11 M) treated a single institution between...

Introduction. Kyphosis is a deformity of the spine characterized by excessive backward curvature thoracic spine. The normal range kyphosis in teenagers 20 - 40 degrees, and diagnosis hyper-kyphosis beyond 45 degrees. aim this review was to assess magnitude effects various corrective exercises on kyphotic angle reduction. Material Methods. Web Science PubMed were searched retrieve relevant liter...

Radiographic sagittal plane analysis of VATS (video-assisted thoracoscopic surgery) anterior instrumentation for adolescent idiopathic scoliosis. This is retrospective study. To report, in details about effects of VATS anterior instrumentation on the sagittal plane. Evaluations of the surgical outcome of scoliosis have primarily studied in coronal plane correction, functional, and cosmetic aspe...
