BACKGROUND: Proximal junctional failure is a severe proximal junctional complication following adult spinal instrumentation and involving acute proximal junctional kyphotic deformity, mechanical failure at the upper instrumented vertebra or just above, and/or proximal junctional osseoligamentous disruption. Clinical studies have identified potential risk factors, but knowledge on their biomechanics is still lacking for addressing the proximal junctional failure issues. The objective of this study was to develop comprehensive computational modeling and simulation techniques to investigate proximal junctional failure...

PURPOSE: Metastatic epidural spinal cord compression (MESCC) often requires anterior-posterior decompression and stabilization. To reduce approach-related complications, single-stage posterolateral vertebrectomy and 360° fusion is often performed. However, a sufficient reduction of kyphotic deformity through this approach has not been reported. The purpose of this study is to investigate the efficacy of kyphotic deformity reduction by this approach in MESCC. METHODS: A retrospective analysis and chart review was performed for 14 consecutive patients who underwent a vertebrectomy and decompression from a posterolateral approach...

Evidence is limited regarding the regional changes in spinal posture after self-correction. The aim of the present study was to evaluate whether active self-correction improved standing and sitting spinal posture. Photogrammetry was used to assess regional spinal curvatures and vertical global spine orientation (GSO) in 42 asymptotic women aged 20-24 years. Upper thoracic spine angle and GSO increased in response to self-correction, while the thoracolumbar and lumbosacral angles decreased. Self-correction in the standing position resulted in decreased inclination of the upper thoracic and thoracolumbar spinal angles...

Spinal kyphotic deformity after spinal laminectomy or laminoplasty is more common in pediatric patients than adults. Laminectomy can lead to decreased cartilage growth, anterior wedging and posterior spinal muscle insufficiency which can result in kyphotic deformity. Herein we outline a case report of a child presenting with kyphotic deformity after receiving a spinal laminectomy to treat a penetrating spinal trauma. The 8-year-old male presented with penetrating spinal trauma following a gunshot wound and subsequently underwent L1 laminectomy and thecal sac decompression to remove the foreign body...

BACKGROUND: Percutaneous kyphoplasty (PKP) could achieve rapid pain relief for older patients with osteoporotic vertebral compression fractures (OVCFs). Bone cement in PKP was the key factor keeping the stabilization of the vertebral body. However, the same amount of cement can distribute differently in a vertebral body and can thereby result in different surgery outcomes. Therefore, the volume and distribution of bone cement should be considered as 2 distinct variables to evaluate the effectiveness of PKP...

OBJECTIVE: Rod-screw fixation systems are widely used for spinal instrumentation. Although many biomechanical studies on rod-screw systems have been carried out, but the effects of rod contouring on the construct strength is still not very well defined in the literature. This work examines the mechanical impact of straight, 20° kyphotic, and 20° lordotic rod contouring on rod-screw fixation systems, by forming a corpectomy model. METHODS: The corpectomy groups were prepared using ultra-high molecular weight polyethylene samples...

AIM The surgical approaches for spinal tumors, to a great extent, have been developed in accordance with the developments in technology. Today, many surgical techniques are implemented as anterior, anterolateral, posterior, posterolateral and combined approach. Due to its low morbidity, posterior approach is more preferred one. Laminectomy is a widely used technique especially in neoplastic lesions. However, following laminectomy, there are complications like instability, kyphotic deformity and scar formation...

Severe os odontoideum causing ventral brainstem compression is a rare and difficult entity to treat. It is generally accepted that severe os odontoideum causing ventral brainstem compression and neurological deficits warrants surgical treatment. This often requires both anterior and posterior procedures. Anterior approaches to the craniocervical junction are fraught with complications, including infection and risk of injury to neurovascular structures. External traction systems traditionally require long-term bedrest...

Patients with adult spinal deformity (ASD) are surgically treated for pain relief; however, visualization of the exact origin of the pain with imaging modalities is still challenging. We report the first case of a 60-year-old female patient who presented with painful degenerative kyphoscoliosis and was evaluated with flourine-18-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography ((18)F-FDG-PET/CT) preoperatively. Because her low back pain was resistant to conservative treatment, she was treated with posterior spinal correction and fusion surgery from Th2 to the ilium...
