Randomized Controlled Trial Comparative Study Clinical Trial
Lumbar epidural perineural injection: a new technique.
Two controlled studies for a new epidural, perineural, single-shot, selective nerve root injection with a double-needle approach to the anterior epidural space of the lumbar spinal canal are presented. The results were analysed to determine the effectiveness of the new epidural perineural injection technique. The trial comprised two controlled studies on 182 patients. ⋯ There were no severe complications or side effects in any of the three groups. The studies concluded that single-shot epidural perineural injection is effective in the treatment of lumbar radicular pain. It is a "one drop only" therapy to the source of pain.

We report a case of a hernia through the thoracolumbar fascia in a young adult male who presented with pain and swelling in the thoracolumbar region. Surgical repair of the defect was performed in the superficial layer of the thoracolumbar fascia and, 18 months following surgery, he remained asymptomatic. The purpose of this report is to make clinicians aware of a thoracolumbar hernia as a rare cause of back pain.

The complications of 648 consecutively inserted Universal AO pedicle screws (140 in the thoracic spine and 508 in the lumbar spine) performed by one surgical team to treat 91 patients with spinal problems, were reviewed. The spinal pathology consisted of: scoliosis (34 patients), degenerative lower lumbar spinal disease (25 patients), neoplastic spinal disease (11 patients), thoracic kyphosis (8 patients), spinal fractures (7 patients), lumbo-sacral spondylolisthesis (3 patients), and osteomyelitis (3 patients). ⋯ Postoperative complications were; deep wound infection (n = 4), screw loosening (n = 2) and rod-screw disconnection (n = 1). The conclusion was that pedicle screw fixation has an acceptable complication rate and neurological injury during this procedure is unlikely.

We report a unique complication caused by the rod of a Harrington instrumentation device, which resulted in spinal stenosis and myelopathy. A literature review revealed no previous causes of direct spinal cord impingement caused by the rod of a Harrington device. In this case, years after the initial operation, the rod penetrated the lamina at the junction between a thoracic and a lumbar curve, causing spinal stenosis and myelopathy. We conclude that regular control of the position of the device and awareness of possible late neurological complications are necessary to identify such complications as early as possible.

Corrective surgery for kyphotic deformities of the spine in ankylosing spondylitis is a major surgery for rare indications. The authors report 31 lumbar osteotomies. The goal is to correct the deformity through a posterior limited approach and to minimise the neurological risks. ⋯ The choice of level depends on secondary effects on pelvic position and projection of the centre of gravity. The preferred procedure remains a monosegmental correction because it is faster and easier, with minimum bleeding. Short monobloc posterior fixation is sufficient to maintain reduction and to obtain stability from posterior compression.
