Comparative Study Controlled Clinical TrialComparison of kyphoplasty and vertebroplasty for treatment of painful osteoporotic vertebral compression fractures: twelve-month follow-up in a prospective nonrandomized comparative study.
A prospective nonrandomized comparative study. ⋯ Kyphoplasty and vertebroplasty demonstrated similar good clinical outcomes during the 12-month follow-up. Kyphoplasty offers a higher degree of spinal deformity correction and results in less cement leakage than vertebroplasty. The benefits of these relative merits need to be ascertained in future long-term studies.

Clinical TrialClinical evaluation of a new kyphoplasty technique with directed cement flow.
Prospective, single-center 2-year study. ⋯ Directed cement flow allows cement to fill the anterior vertebral body, stabilizing fractures and supporting biomechanical loading. Control of cement flow may help minimize the risk of posterior leakage into the basivertebral vein or spinal canal.

Comparative StudyThree-dimensional kinematic lumbar spine motion analyses of trunk motion during axial rotation activities.
An experimental design was conducted to investigate kinematic changes in 3-dimensional trunk motions between subjects with and without chronic low back pain (LBP) while demonstrating axial rotation. ⋯ Decreased spinal range of motion in older subjects might result in a stiffened spine in addition to possible poor proprioception from back injuries to passive structures in subjects with chronic LBP.

Retrospective. ⋯ Our findings suggest that the Tai Chi pedicle screw placement technique, which does not require intraoperative radiographic imaging, is an accurate, reliable, safe, and time-saving method of placing pedicle screws in severe scoliotic spines.

Case ReportsImpact of prone surgical positioning on the scoliotic spine.
To study the impact of patient-specific prone positioning on the sagittal and coronal curves of scoliotic spines, including the impact of various patient and surgical frame factors. ⋯ Prone positioning results in a reduction of all spinal segmental curves which is dependent on a number of patient and surgical frame factors.
