At the head-trunk transition, hindbrain and spinal cord alignment to occipital and vertebral bones is crucial for coherent neural and skeletal system organization. Changes in neural or mesodermal tissue configuration arising from defects in the specification, patterning or relative axial placement of territories can severely compromise their integration and function. Here, we show that coordina...

The purpose of this study was to determine whether sagittal plane posture differed between fallers and nonfallers and to explore the relationship between skeletal alignment and balance in elderly females. Forty-eight women > 65 years of age were recruited from various medical and senior citizen centers. Thirteen of these women were classified as fallers. Spinal posture was measured in standing ...

We report on a 12-year-old boy in whom a glass fragment migrated into the lumbar spinal canal causing low back pain and radiculopathy 6 years after injury. Computed tomography showed a foreign body in the anterior spinal canal of L5/S1. The patient underwent recapping T-saw laminoplasty to remove the foreign body. Scar formation was noted at the anterior dura. The glass fragment seemed to have ...

OBJECTIVE Restoration of lumbar lordosis is a critical factor in long-term success after lumbar fusions. Transforaminal lumbar interbody fusion (TLIF) is a popular surgical technique in the lumbar spine, but few data exist on change in spinal alignment after the procedure. METHODS Eighty patients who underwent TLIF surgery were retrospectively reviewed (minimum follow-up period, 2 years). Sta...

To examine whether the association between spinal alignment and sacral anatomical orientation (SAO) can be detected in skeletal populations, by comparing SAO values in individuals with a typical SD to individuals with normal spinal alignment. 2025 skeletons were screened for Scheuermann's disease. Scheuermann's kyphosis was established by the presence of apophyseal abnormalities associated with...

Minimally invasive transforaminal lumbar interbody fusion (TLIF) as a short fusion is widely accepted among the spine surgeons. However in the long fusion for degenerative kyphoscoliosis, corrective spinal fixation by an open method is thought to be frequently selected. Our objective is to study whether the mini-open TLIF and corrective TLIF contribute to the improvement of the spinal segmental...

There is no universal agreement on the best procedure for treating lower cervical dislocation because anterior reduction and interbody fusion fixation have not been directly compared to posterior short-segmental pedicle screw fixation. This study compares long-term effects of severe with spinal cord injury treated using an versus a method. A total 149 patients (follow-up rate 84.1%) could be fo...

BACKGROUND Failed fusion surgery remains difficult to treat. Few published data on disc replacement surgery after failed fusion procedures exist. Our objective was to evaluate outcomes of junctional lumbar disc replacement after previous fusion surgery and to correlate outcome with radiological changes to parameters of sagittal balance. METHODS Out of a single-center prospective registry of 2...
