Comparative Study
Health-related quality of life in patients with adolescent idiopathic scoliosis after treatment: short-term effects after brace or surgical treatment.
For treatment of teenagers with progressive adolescent idiopathic scoliosis in an early stage, two options are generally considered: treatment with a brace or observation followed by surgery if necessary. Many doctors and patients prefer conservative treatment (i.e. brace treatment) to surgical treatment, because surgery of the spine is generally considered a drastic intervention. Because potential differences in health-related quality of life (HRQoL) after treatment between braced and surgically treated patients are not well explored, this study aimed to determine whether short-term differences exist in HRQoL between adolescents treated with a brace or treated surgically. ⋯ No other consistent differences in HRQoL were found between patients treated with a brace and patients treated surgically. Gender, curve type and curve size had no relevant effect on HRQoL. We conclude that short-term differences in HRQoL after treatment in adolescent patients with idiopathic scoliosis are negligible and cannot support preference of one treatment above the other.

This morphometric and experimental study was designed to assess the dimensions and axes of the subaxial cervical pedicles and to compare the accuracy of two different techniques for subaxial cervical pedicle screw (CPS) placement using newly designed aiming devices. Transpedicular fixation is increasingly used for stabilizing the subaxial cervical spine. Development of the demanding technique is based on morphometric studies of the pedicle anatomy. ⋯ Because of the variability of cervical pedicles preoperative CT evaluation with multiplanar reconstructions of the pedicle anatomy is essential for transpedicular screw placement in the cervical spine. Cadaver studies remain mandatory to develop safer and technically less demanding procedures. A similar study is projected to further develop the technique of CPS fixation with regard to safety and clinical practicability.

Low back and pelvic pain (LBPP) is prevalent during pregnancy and also post-partum. The aetiology is poorly understood. The aim of this study was to investigate possible associations between epidural or spinal anaesthesia and caesarean section (CS) with persistent LBPP half a year after pregnancy. ⋯ Epidural or spinal anaesthesia was not associated with risk of persistent LBPP. Elective CS was associated with an increased risk of persistent LBPP. However, the results must be interpreted with caution because of a relatively small study sample.

Clinical Trial
Interobservational variation in determining fusion rates in anterior cervical discectomy and fusion procedures.
The fusion rate represents one of the most commonly used criteria for evaluating the efficacy of spinal surgical techniques and the effectiveness of newly developed instrumentation and spinal implants. Reported fusion rates are not frequently supported by adequate information regarding by whom and how fusion was defined. In our prospective study we examined the fusion rate in patients undergoing first time anterior cervical discectomy and fusion for degenerative disease. ⋯ Our findings confirm the necessity of defining and describing criteria for fusion whenever this rate is reported in clinical series. The lack of widely accepted, well-defined criteria makes comparison of these results difficult. The development of a well organized, prospective clinical study in which fusion and outcome will be assessed by both clinical and radiographic parameters could significantly contribute to a more accurate evaluation of overall outcome of cervical spinal procedures.

Comparative Study
Anterior versus posterior surgery for osteoporotic vertebral collapse with neurological deficit in the thoracolumbar spine.
Despite the increasing number of reports on surgical treatments for thoracolumbar osteoporotic vertebral collapse with neurological deficits, the choice of surgery remains controversial. In this retrospective study, we compared the outcomes of posterior and anterior surgeries for single-level osteoporotic vertebral collapse with neurological deficit in the thoracolumbar spine. Both posterior and anterior surgical approaches were performed with a consistent procedure for a single surgical indication at one institution. ⋯ None of the patients developed instrumentation-related neurological problems. Two cases in each group developed pseudoarthrosis. In single-level osteoporotic vertebral collapse with neurological deficit, anterior surgery tended to improve neurological deficit in wedge type, but not in flat type collapse, compared with posterior surgery.
