Whilst neurologic injury following correction of scoliosis with CD-instrumentation is generally known to be an early complication, any late occurrence of cauda compression secondary to employment of a laminar hook-rod construct is exceptional. We report on such a rare case of late occurrence of cauda equina syndrome, when a laminar hook at level L2 became symptomatic causing compression of the cauda equina almost a decade after spine surgery. This case demonstrates that one should not only be aware of a potential neural injury at intraoperative placement of laminar hooks, but also one is reminded that a laminar hook poses the threat of late neurologic injury years after successful osseous spinal fusion. The surgeon treating patients with scoliosis must be aware of the possible complication described in our patient in addition to those that have already been well documented.

There continues to be controversy surrounding the management of thoracolumbar burst fractures. Numerous methods of fixation have been described for this injury, but to our knowledge, spinal fusion has always been part of the stabilising procedure, whether this involves an anterior or a posterior approach. Apart from an earlier publication from this centre, there have been no reports on the use of internal fixation without fusion for this type of fracture. ⋯ The only significant factor affecting outcome was the influence of a compensation claim (P < 0.05). The implant failure rate (14% of patients) and the clinical outcome was similar to that from series where fusion had been performed in addition to pedicle screw fixation. The results of this study support the view that posterolateral bone grafting is not necessary when managing patients with thoracolumbar burst fractures by short segment pedicle screw fixation.

The authors present their experience in the operative treatment of unstable lesions at the cervicothoracic junction. Ten patients, six men and four women, underwent operative procedures at the cervicothoracic junction (C7-T1) between 1990 and 1997. Six patients had sustained fracture-dislocations, three patients had metastases and one patient had a primary malignant lesion. ⋯ Five patients were submitted to a posterior operation only, and the other five to bilateral procedures. In four of these a one-stage operation was performed and in the last case a two-stage procedure. The anatomic and biomechanical characteristics of the cervicothoracic junction require a precise pre-operative analysis of the local anatomy and the selection of the proper implants for anterior and posterior stabilization.

Review Case Reports
Cervical synovial cysts: case report and review of the literature.
The authors describe the case of a 58-year-old man with a 6-month history of severe myelopathy. CT scan and MRI of the spine revealed a cystic formation, measuring about 1 cm in diameter, at C7-T1 at a right posterolateral site at the level of the articular facet. At operation the mass appeared to originate from the ligamentum flavum at the level of the articular facet and was in contact with the dura mater. ⋯ There may also be a hypointense rim on T2-weighted images, which enhances after i.v. administration of gadolinium. Surgical treatment consists of removal of the mass. Fixation of the vertebral segments involved is not always necessary.

Low back pain (LBP) among children and adolescents has become the subject of an increasing amount of literature over the last 15 years. This topic, which was considered almost insignificant less than two decades ago, was the focus of a recent international meeting organised in Grenoble (France) in March 1999. This review paper is the result of an literature update search performed by members of three groups which have been active in this field for many years. Current epidemiological data on LBP is summarized as well as the role of the major risk factors according to studies published in the principal peer reviewed journals interested in the topic.
