In severe congenital scoliosis, traction (whether with a halo or instrumental) is known to expose patients to neurologic complications. However, patients with restrictive lung disease may benefit from halo traction during the course of the surgical treatment. The goal of treatment of such deformities is, therefore, twofold: improvement of the respiratory function and avoidance of any neurologic complications. ⋯ Her definitive surgery consisted of locking the dominoes and the application of a contralateral rod. Satisfactory outcome was achieved for both correction of the deformity (without neurologic sequels) and improvement of her pulmonary function (1200 c.c. at 2 years). This technique using sliding rods in combination with halofemoral traction can be useful in high-risk, very severe congenital scoliosis.

This study was designed as a cross-sectional questionnaire-based survey of low back pain (LBP) in 13- to 16-year-old Danish school children. The cohort consisted of 671 boys and 718 girls in eighth and ninth grade in 46 municipal schools in three counties of Sealand. All the pupils filled in a questionnaire with LBP as the main topic and were at the same time examined by the school doctors. ⋯ This was positively correlated to female gender, BMI more than 25 kg/m(2), competitive sport for boys, poor physical fitness, daily smoking, heavy jobs in leisure time, increased use of the health system and reduced life quality. Stepwise logistic regression analysis indicates that female gender, daily smoking and heavy jobs are important associated factors for severe LBP in adolescents, with an observed probability of 46% if all factors are present. We don't know yet whether these factors are of any causal importance in the development of severe LBP.

Case Reports
Unusual presentation of spinal cord compression related to misplaced pedicle screws in thoracic scoliosis.
Utilization of thoracic pedicle screws is controversial, especially in the treatment of scoliosis. We present a case of a 15-year-old girl seen 6 months after her initial surgery for scoliosis done elsewhere. She complained of persistent epigastric pain, tremor of the right foot at rest, and abnormal feelings in her legs. ⋯ At the time of the revision surgery the somatosensory evoked potentials (SSEP) returned to normal after screw removal. The clinical symptoms resolved 1 month after the revision. The authors conclude that after pedicle instrumentation at the thoracic level a spinal cord compression should be looked for in case of subtle neurologic findings such as persistent abdominal pain, mild lower extremity weakness, tremor at rest, thermoalgic discrimination loss, or unexplained imbalance.

Case Reports
Myelopathy due to calcification of the cervical ligamenta flava: a report of two cases in West Indian patients.
Two cases of cervical myelopathy due to calcification of the ligamenta flava (CLF) are described for the first time in black patients from the French West Indies. A pre-operative CT scan differentiated the diagnosis from one of ossification of the ligamenta flava. Microanalysis on the operatively excised specimen in one patient revealed a mixture of calcium pyrophosphate dihydrate crystals and hydroxypatite crystals. Poor outcome in one patient contrasting with excellent recovery in the other one, who had undergone posterior decompressive laminectomy, emphasizes the importance of surgery in the management of CLF.

This study retrospectively reviews 20 sequential patients with thoracolumbar burst fractures without neurologic deficit. All patients were treated by indirect reduction, bisegmental posterior transpedicular instrumentation and monosegmental fusion. Clinical and radiological outcome was analyzed after an average follow-up of 6.4 years. ⋯ Therefore, posterolateral fusion alone does not prevent disc space collapse. Nevertheless, clinical long-term results are favorable. However, if disc space collapse has to prevented, an interbody disc clearance and fusion is recommended.
