A 67-year-old patient suffered a fall and sustained injuries to the thorax, combined with fractures of the ribs, sternum and thoracic spine. Her pre-existing kyphosis (caused by osteoporotic vertebral collapse) increased in severity. There was a clear relationship between a sternal fracture, deterioration of thoracic kyphosis and a fracture of the thoracic spine.

Comparative Study
Three-dimensional measurement of wedged scoliotic vertebrae and intervertebral disks.
Idiopathic scoliosis involves complex spinal intrinsic deformations such as the wedging of vertebral bodies (VB) and intervertebral disks (ID), and it is obvious that the clinical evaluation obtained by the spinal projections on the two-dimensional (2D) radiographic planes do not give a full and accurate interpretation of scoliotic deformities. This paper presents a method that allows reconstruction in 3D of the vertebral body endplates and measurement of the 3D wedging angles. This approach was also used to verify whether 2D radiographic measurements could lead to a biased evaluation of scoliotic spine wedging. ⋯ There was no statistical relation between the 2D radiographic angles and the locations of the 3D intervertebral wedging angles. These results clearly indicate that VB and ID endplates are wedged in 3D, and that measurements on plain radiographs allow incomplete evaluation of spinal wedging. Clinicians should be aware of these limitations while using wedging measurements from plain radiographs for diagnosis and/or research on scoliotic deformities.

Halm-Zielke instrumentation (HZI) was developed to eliminate the disadvantages of Zielke instrumentation (VDS) in terms of lack of primary stability and a kyphogenic effect. HZI is an anterior double-rod system. The system is composed of a lid-plate, which is fixed at the lateral aspect of the vertebral body with two screws, a sunk screw anteriorly and a VDS screw posteriorly. ⋯ All patients were treated without any additional external immobilization. In our opinion, HZI is a major improvement on the original Zielke VDS. It eliminates the kyphogenic effect and provides primary stability.

Comparative Study
Functional outcome after posterolateral spinal fusion using pedicle screws: comparison between primary and salvage procedure.
Lumbar spinal fusion is a commonly performed surgical procedure, yet both the indications for its performance and its results remain controversial. It is generally believed that apart from situations where obvious measurable instability exists, a repeat surgical procedure such as spinal fusion does not improve the functional outcome in more than an average of 50% of cases. The aim of this study was to analyse functional outcome after posterolateral lumbar or lumbosacral spinal fusion, comparing primary and salvage procedures. ⋯ This study demonstrates that a posterolateral spinal fusion can be effectively used as a salvage procedure. The functional and radiological outcome of the patients with revision surgery did not differ from those of the group of patients who underwent primary surgery. There was, however a clear indication of inferior social functioning after revision surgery.

Randomized Controlled Trial Clinical Trial
Conservative treatment in patients sick-listed for acute low-back pain: a prospective randomised study with 12 months' follow-up.
We evaluated three different conservative treatment methods for acute low-back pain patients in groups following a manual therapy programme, an intensive training programme, or a general practitioner programme, the latter serving as the control group. Patients aged 19-64 years on sick leave for low-back pain with or without sciatica were included in a prospective randomised study evaluating outcomes such as impairment, pain, functional disability, socio-economic disability and satisfaction with the treatment or explanations. Evaluation by unbiased observers was performed at 1, 3 and 12 months. ⋯ All three study groups showed rapid improvement. After 1 month a significant improvement was noted in all outcome values compared with the values on entry to the study. Within the limitations discussed in our study, it is concluded that (1) patients sick listed with acute low-back pain, with or without sciatica, will be significantly improved after 1 month regardless of conservative treatment programme; (2) they will be more satisfied with the treatment if they are referred to a manual treatment programme or a training treatment programme; (3) they will be more satisfied with the explanations of the acute low-back problem if they are referred to one of the above groups, especially the manual treatment group; (4) they will not show any other differences with respect to subjective and objective variables, either at short-term or at long-term follow-ups.
