The use of transperitoneal endoscopic approaches to the distal segments of the lumbar spine has recently been described. This has been the catalyst for the development of other minimally invasive anterior approaches to the spine. ⋯ The efficacy and safety of minimal access techniques in the spine have been established, and outcome standards set by which future techniques can be judged. The importance of proper training is emphasised.

Retroperitoneal videoscopic spine surgery has been developed in our department since 1994. It has been used not only at the lumbar, but also at the thoracolumbar and lumbosacral level. Thirty-eight patients have been operated on. ⋯ The complications related to the approach were the same as those seen with open surgery; however, the videoscopic approach seems to us less invasive, with cosmetic benefit, less blood loss, and more rapid recovery. A video-assisted technique appears to be a good compromise between videoscopic technique and open surgery. With the development of these techniques, few indications remain for open anterior surgery on the lumbar spine in our opinion.

A 17-year-old patient with pre-existing grade II spondylolisthesis of L5/S1 sustained a partial disruption of the left sacroiliac joint with haematoma of the iliac muscle after a fall. The haematoma probably led to occlusion of the left ureter, resulting in a urinary tract infection. After initial conservative treatment the patient developed fever and radicular pain of the left leg. ⋯ Staphylococcus aureus was identified as the pathogen. At follow-up 6 months postoperatively all symptoms had resolved, while MRI still revealed residual osseous oedema of the sacroiliac joint. The haematoma of the iliac muscle resolved without surgical intervention.

Four cases of aspergillus spondylodiscitis were treated with operative debridement and fusion. In this rarely encountered mycotic infection of the spine in immunocompromised patients rapid destruction of the intervertebral disc and vertebral bodies can occur. In advanced cases antimycotic drug therapy is thought to be ineffective and a forcing indication for surgery exists when the destruction is progressive and spinal cord compression is imminent or manifest. ⋯ In two of three patients with a neurologic deficit, this deficit disappeared. Two patients died within 6 months after the operative treatment, due to complications related to the underlying illness. One patient was left with a subtotal paraplegia.

Comparative Study
Sagittal alignment in lumbosacral fusion: relations between radiological parameters and pain.
The objective of this study was to conduct a radiological analysis of posture before and after lumbosacral fusion to evaluate the influence of spinal alignment on the occurrence and pattern of post surgical pain. The study included 81 patients, of whom 51 had a history of previous low back surgery. We excluded patients with suspected or confirmed nonunion. ⋯ Appropriate position of the fused vertebrae is also of paramount importance to minimize muscle work during posture maintenance. The main risk is failing to correct or to causing excessive pelvic retroversion with a vertical sacrum leading to a sagittal alignment that replicates the sitting position. This situation is often accompanied by loss of lumbar lordosis and adversely affects stiff or degenerative hips.
