The relationship between the Tampa Scale of Kinesiophobia and low back pain rehabilitation outcomes.
The Tampa Scale for Kinesiophobia (TSK) is commonly used in clinical practice to quantify levels of pain-related fear of activity or re-injury in patients presenting with back pain. Patients with high levels of kinesiophobia are often considered at greater risk of developing long-term activity limitation and chronicity. There is, however, little evidence to support this assumption. ⋯ The TSK provides no benefit as a screening tool to predict pain, functional and work outcomes following rehabilitation. Measured changes in TSK scores following rehabilitation do not correlate strongly with similar, concordant changes in pain scores, functional levels, or return-to-work outcomes.

There have been no previous studies looking at the outcome of surgical decompression (+/-stabilization) for various grades of epidural spinal cord compression (ESCC) due to spinal metastases. ⋯ Surgery can achieve improvements in neurology even in higher grades of cord compression. There is a trend toward more complications and worse survival with spinal surgery in patients with higher grades of compression.

There is little information regarding the surgical outcomes with regard to the timing of surgery in children under age 10 years for congenital scoliosis with a long-term follow-up. ⋯ In congenital scoliosis patients, posterior hemivertebra resection after pedicle screw fixation before the age of 6 years had significantly better deformity correction and did not cause a negative effect on the growth of vertebral body or spinal canal compared with the group treated after 6 years of age. Therefore, early surgical correction of a congenital hemivertebra in children under 6 years of age, before structural changes occur, effectively achieves a more satisfactory correction without causing iatrogenic spinal stenosis or neurologic complications compared with children older than 6 years but under 10 years of age.

Short-segment pedicle screw instrumentation constructs for the treatment of thoracolumbar fractures gained popularity in the 1980s. The load-sharing classification (LSC) is a straightforward way to describe the extent of bony comminution, amount of fracture displacement, and amount of correction of kyphotic deformity in a spinal fracture. There are no studies evaluating the relevance of fracture comminution/traumatic kyphosis on the long-term radiologic outcome of burst fractures treated by short-segment instrumentation with screw insertion in the fractured level. ⋯ The six-screw construct is effective for treating thoracolumbar junction burst fractures. The medium-to-long-term loss of correction is affected by the amount of bony comminution of the fracture, objectified through the LSC score.

Facet joint orientation and tropism influence the biomechanics of the corresponding segment. Therefore, the sagittal orientation or tropism of the facet joint adjacent to the fusion segment seems a potential risk factor for adjacent segment degeneration. However, there have been no biomechanical studies regarding this issue. ⋯ Facet joint orientation and tropism at the adjacent segment influences the overstress of the adjacent segment, especially under the clinical circumstance of increased anterior shear force.
