Evaluation and comparison of translated and culturally adapted self-reported measurements. ⋯ QBPDS-PL and RODI-PL are reliable and valid. Furthermore, investigation of the psychometric properties of the LBOS-PL in different spinal conditions is required. There is a relation between the results of the QDS-PL, and different levels of advancement in degenerative disease of the lumbar spine, according to the Modic Classification.

Case Reports
Nightmare complication after lumbar disc surgery: cranial nontraumatic acute epidural hematoma.
Case report. ⋯ There have been described rare cases of spontaneous subdural, intracerebral, and intracerebellar hematoma caused by intracranial hypotension, but this is the first described case of spontaneous cranial epidural hematoma after lumbar disc surgery caused by intracranial hypotension.

Prospective, intraoperative force measurement in consecutive lengthening procedures in a series of growing-rod patients undergoing lengthening. ⋯ Distraction forces increase significantly after repeated lengthening of growing-rod constructs, and the length obtained at each procedure exhibits a decreasing trend.

Randomized Controlled Trial Multicenter Study
Cost-effectiveness of balloon kyphoplasty versus standard medical treatment in patients with osteoporotic vertebral compression fracture: a Swedish multicenter randomized controlled trial with 2-year follow-up.
A multicenter, randomized, controlled, cost-effectiveness analysis. ⋯ In this randomized controlled trial, it was not possible to demonstrate that BKP was cost-effective compared with standard medical treatment in patients treated for an acute/subacute vertebral fracture due to osteoporosis. However, sensitivity analysis indicated a certain degree of uncertainty, which needs to be considered.
