Overall anatomical features and clinical value of the sacral nerve in high resolution computed tomography reconstruction.

Background: Sacral nerve injury is a common complication of pelvic or sacral fractures. As the sacral nerve courser within the sacrum and has a complex relationship with the surrounding tissues, different parts of the sacral plexus injury have similar clinical symptoms and signs. Since lack of specific imaging technique in the diagnosis of sacral nerve injury, especially on multi-segment, multi-site, how to determine the preoperative location and extent of the sacral nerve injury accurately becomes a concern of the general orthopaedic and images practitioners.

[Study on the overall anatomical features and clinical value of lumbar nerve root, plexus and branches in CT reconstruction].

Objective: To identify the overall anatomical characteristics and the clinical value of the lumbar nerves under CT multiplanar reconstruction.

Methods: Fifty normal subjects and 30 patients with LN diseases (51 sides) were selected, including 10 patients with lumber intervertebral disk hernia, eight patients with spinal stenosis, 5 patients with spondylolisthesis, 1 patient with tethered cord syndrome, 1 patient with lumbar scoliosis, and 5 patients with spinal trauma The 16-slice helical CT (Light Speed, GE Company) was used for scanning the lumbar vertebra with multiplanar reconstruction in Workstation (ADW4.1) with UNIX System in DICOM format.

[Features of obturator nerve by high-resolution CT at the same slice with multiplanar planar reconstruction techniques and clinic value thereof].

Objective: To explore the features of obturator nerve (ON) by high-resolution CT (HRCT) at the same slice with multiplanar planar reconstruction techniques and clinic value thereof.

Methods: The normal lumbar vertebral bodies of 60 healthy adults and the abnormal lumbar vertebral bodies of 31 patients with ON disorders were scanned with 16-slice spiral CT, multiplanar reconstruction was conducted in the Workstation ADW4. 1, with UNIX system and DICOM form.

[Value of multiplanar reconstruction of lumbar nerve roots on the same level by high resolution computed tomography in diagnosis of lumbar disc herniation and/or bulge].

Objective: To explore value of multiplanar reconstruction of lumbar nerve roots on the same level by high resolution computed tomography (HRCT) in diagnosis of lumbar disc herniation and/or bulge (LDHB).

Methods: Thirty-one patients with manifestations of typical nerve root compression, such as lumbago and tenderness of percussion pain at the corresponding sites were scanned with 16-slice spiral CT and multiplanar reconstruction of lumbar nerve roots on the same level with the workshop ADW4.150, and were diagnosed as with LDHB with 50 segments.
