Lumbar fusion using the pedicle screw system is a popular operative procedure, with favorable clinical results and high fusion rates. However, the risk of adjacent segment disease after lumbar fusion is problematic. We report a complicated case of severe retrolisthesis at L3-4 level following dynamic interspinous process stabilization at L2-3 level and a fusion at L4-5 level. The radiological a...

The C1-2 complex allows far more motion than any other single level in the cervical spine. This motion is predominantly rotational, since translational motion at C1C2 is limited by the strong transverse ligament. This restriction is lost after fracture of the odontoid and may be associated with anteroor retrolisthesis of the C1-C2 complex in relation to the C2 body. This may result in spinal co...

The study was to comprehensively compare the postoperative outcome and imaging parameter characters in a short/middle period between the percutaneous endoscopic lumbar discectomy (PELD) and the internal fixation of bone graft fusion (the most common form is posterior lumbar interbody fusion [PLIF]) for the treatment of adjacent segment lumbar disc prolapse with stable retrolisthesis after a pre...
