BACKGROUND Lateral approach to lumbar fusion has been gaining popularity in recent years. With increasing awareness of the significance of sagittal balance restoration in spinal surgery, it is important to investigate the potential of this relatively new approach in correcting sagittal deformities in comparison to conventional approaches. The aim of this study was to evaluate sagittal contour c...

AIM Our goal was to investigate the long-term results of anterior lumbar interbody fusion combined with percutaneous pedicle screw fixation for degenerative lumbar instability. MATERIAL AND METHODS Forty-seven patients that had undergone anterior lumbar interbody fusion combined with percutaneous pedicle screw fixation for degenerative lumbar instability at Tianjin Hospital between May 2003 a...

Degenerative changes of the knee often cause loss of extension. This may affect aspects of posture such as lumbar lordosis. A total of 366 patients underwent radiological examination of the lumbar spine in a standing position. The knee and body angles were measured by physical examination using a goniometer. Limitation of extension of the knee was significantly greater in patients whose lumbar ...

This study aims to assess the differences in the radiological and clinical results depending on the lordotic angles of the cage in posterior lumbar interbody fusion (PLIF). We reviewed 185 segments which underwent PLIF using two different lordotic angles of 4° and 8° of a polyetheretherketone (PEEK) cage. The segmental lordosis and total lumbar lordosis of the 4° and 8° cage groups were compare...

OBJECTIVE To test the hypothesis that restoring the lumbar lordosis will increase a patient's voluntary muscular strength and decrease back pain symptoms. CLINICAL FEATURES A patient was diagnosed with mechanical low back pain. The initial radiographic study revealed a loss of the lumbar lordosis. The patient determined his maximum bench press prior to the treatment program. The treatment out...

Subchondral insufficiency fracture (SIF) of the femoral head occurs in the elderly and recipients of organ transplantation. Osteoporosis and deficient lateral coverage of the acetabulum are known risk factors for SIF. There has been no study about relation between spinopelvic alignment and anterior acetabular coverage with SIF. We therefore asked whether a decrease of lumbar lordosis and a defi...

abstract objective: to present the changes in projected thoracic hypokyphosis and the behavior of lumbar lordosis within and below the fusion and to compare these changes between the harrington rod (hr) and posterior multisegmented hook instrumentation. methods: 178 patients with idiopathic scoliosis, who had undergone posterior spinal fusion with harrington technique (106 patients) or multiseg...

BACKGROUND CONTEXT: Lateral approach to lumbar fusion has been gaining popularity in recent years. It utilises a retroperitoneal transpsoas approach to reach the disc space in a minimally invasive fashion. It allows better access for disc clearance and insertion of large foot print cages. PURPOSE: To compare radiographic and clinical results following lateral lumbar interbody fusion (LLIF) and ...

STUDY DESIGN Prospective cohort study. PURPOSE To evaluate the contribution of upper and lower lumbar segments to flexion and extension of the lumbar spine in normal and diseased spines. OVERVIEW OF LITERATURE The specific contributions of upper and lower lumbar segments during flexion/extension have rarely been reported. Furthermore, no comparisons between the flexion/extension behaviors o...
