This study analyzed transverse facet joint angulations at the three lower lumbar levels in 132 patients assigned to one of four groups. Group A comprised 23 patients with degenerative spondylolisthesis (DS) at the level L4-5, group B comprised 40 patients above the age of 50 years, group C comprised 38 patients aged between 35 and 50 years, and group D(More)
Degenerative spondylolisthesis (DS) is a common condition of the aging spine, but the underlying pathomechanisms remain controversial. Most previous studies focused on the role of facet-joint alignment and reported a pronounced sagittal orientation. This, however, may also be a secondary feature to the slippage. This study analyzed several radiologic(More)
The study investigates lower lumbar segments with posterior vertebral shifts (retrolisthesis) with respect to the orientation of facet joints, disc height, lordosis of the lumbar spine, and orientation of vertebral endplates. Standing lumbar radiographs as well as CT and/or MRI investigations of 69 patients were analyzed. Data from patients with(More)
Destruction of the second cervical vertebra leads to a highly unstable situation. Reconstruction is difficult because the axis plays a central role in rotatory movements and has a unique function in redistributing axial loads. The axis transfers the axial load of the two lateral masses of the atlas to three surfaces on the third cervical vertebra: the two(More)
BACKGROUND Congenital scoliosis due to hemivertebrae usually progresses during further growth and leads to severe deformities. Early correction in young children is therefore required. PATIENTS Thirty-six hemivertebrae in 33 children aged 1 to 6 years (average 3 years 5 months) underwent surgical intervention. Mean follow-up was 4.5 years (2 months to 13(More)
There is increasing awareness of the need for pedicle screw constructs in the treatment of spinal deformities in very young children. However, the long-term effects of pedicle screws on the immature spine are still unclear. We used a porcine model to analyze the morphological changes of the spinal canal and vertebral body in response to the placement of(More)
STUDY DESIGN A case report of traumatic atlantooccipital dislocation (AOD) managed by intraarticular-posterior fusion from a posterior approach at the C0-C1 level with preservation of C1-C2 motion. OBJECTIVE To present a new technique for atlantooccipital fusion with long-term follow-up. SUMMARY OF BACKGROUND DATA There is an increasing number of(More)
PURPOSE According to literature there is a pseudarthrosis rate of about 1% up to 64% depending on the treatment of the dens fracture (16). Generally the treatment of dens pseudarthrosis consists of the fusion of the joint C1/C2 with or without dens resection. Now, a method is presented whereby, on the one hand the pseudarthrosis is treated, while on the(More)
STUDY DESIGN This was a prospective study of two cohort groups of patients (one group receiving anterior instrumentation and the other posterior instrumentation) receiving treatment for thoracic idiopathic scoliosis. OBJECTIVE To present the 2-year postoperative results of a prospective multicenter study comparing the use of anterior instrumentation with(More)
