BACKGROUND CONTEXT In situ fusion is the gold standard method of treatment of spondylolisthesis. There is no study in the literature evaluating the effect of sagittal contour realignment on clinical outcomes in comparison with the addition of anterior slippage reduction. PURPOSE The correction of sagittal plane vs. reduction with instrumentation in the patients with low or high dysplastic spo...

OBJECTIVE To identify the characteristics of patients with spinal cord injury (SCI) undergoing surgery. METHODS Previously, 321 patients with SCI were selected. Clinical and socio-demographic variables were collected. RESULTS A total of 211 patients were submitted to surgery. Fall and injuries in the upper cervical and lumbosacral regions were associated with conservative treatment. Patient...

BACKGROUND Posterior decompression, instrumentation, and posterolateral fusion are surgical procedures for the treatment of degenerative lumbar diseases. Solid fusion usually causes adjacent problems. This study investigated the clinical outcome and radiographic fate of the L5-S1 segment in patients who underwent posterior instrumented surgery for degenerative lumbar diseases. METHODS From Ja...

EDUCATIONAL OBJECTIVES As a result of reading this article, physicians should be able to: 1. Understand the forces that predispose adjacent cervical segments to degeneration. 2. Understand the challenges of radiographic evaluation in the diagnosis of cervical and lumbar adjacent segment disease. 3. Describe the changes in biomechanical forces applied to adjacent segments of lumbar vertebrae wit...

Background: Intraspinal synovial cysts (SCs) are uncommon benign growths that occur adjacent to the spinal facet joints. Surgical resection is the treatment of choice for symptomatic patients, but, much debate continues regarding the indication of concomitant fusion to prevent delayed instability. In this study, we report a retrospective review of 40 patients treated for lumbar SCs with microsu...

BACKGROUND In instrumented posterolateral fusion reduction of a spondylolisthesis is appealing on theoretical grounds since this may lead to indirect decompression of the entrapped nerve roots. However, there is no consensus in the literature whether a beneficial effect of reduction on outcome can be expected. The objective of the current study was to evaluate whether a correlation between the ...

BACKGROUND The occipitocervical contoured rod (CR) stabilization for use in craniovertebral junction (CVJ) pathologies is an effective and economical technique of posterior fusion (PF). AIMS The various indications for CR in CVJ pathologies are discussed. SETTINGS AND DESIGN Retrospective analysis. MATERIALS AND METHODS Fifty-four patients (mean age: 31.02+/-13.44 years; male: female rati...

Introduction Unilateral pedicle screw fixation and transforaminal cage for interbody fusion are well-established form of treatment for lumbar spondylolisthesis. It is cost effective and has shown to have a comparable outcome to bilateral pedicle screw fixation. We present a case of unilateral pedicle screw fixation and transforaminal cage for interbody fusion in a patient of Grade 1 Degenerativ...

I In nt tr ro od du uc ct ti io on n: : Spinal fusion with instrumentation is an essential component in the management of degenerative condition in the spinal motion segment. It is performed to improve initial stability with simplified external fixation for early ambulation1)2). The solid fixation, however, often induces an adjacent segment degeneration (ASD) above or below the fusion 3). ASD c...

BACKGROUND This is a retrospective review of 25 patients with severe lumbar nerve root compression undergoing multilevel anterior retroperitoneal lumbar interbody fusion and posterior instrumentation for deformity. The objective is to analyze the outcomes and clinical results from anterior interbody fusions performed through a lateral approach and compare these with traditional surgical procedu...
