Spine

We investigated the mechanical load of the lumbar spine caused by changes of posture and carried load. ⋯ We found that the increase of the actual spinal load during trunk flexion in healthy individuals consisted of the theoretical spinal load and load generated by the back muscle activities.

Retrospective single-center consecutive case series with two [corrected] year follow-up. ⋯ Kyphoplasty markedly improves clinical outcome [corrected] and results in significant vertebral height restoration and normalization of morphologic shape indices [corrected] that remain stable for at least two [corrected] years following treatment.
-
A case report. ⋯ It must be kept in mind that cervical spine surgery is not an exceptional precipitator of cervical dystonia, despite the fact that it is extremely rare.

Seventeen healthy volunteers were subjected to right and left lateral impacts 5.0, 6.8, 9.2, and 16.8 m/s acceleration while positioned in a Volvo car seat with lap and shoulder seat belt restraint in laboratory setting. ⋯ Compared with previously reported impact studies with a 5-point harness and rigid seat, the use of a 3-point lap and shoulder seat belt with car seat does not appear to adversely affect the cervical muscle response. In very-low- and low-velocity impact experiments, seat belt and seat type may thus not be particularly relevant to cervical EMG and kinematics.

A retrospective review. ⋯ Harvesting cancellous autograft anteriorly from the lumbar spine using a trephine technique appears to be safe and reliable, with satisfactory fusion rates. Iliac crest graft harvesting with its attendant morbidity is avoided.
