Comparative StudyLong-term follow-up after open-window corpectomy in patients with advanced cervical spondylosis and/or ossification of the posterior longitudinal ligament.
Prospective study was performed in case with cervical spondylosis and ossification of the posterior longitudinal ligament (OPLL). ⋯ Long-term follow-up indicates that OWC yields satisfactory clinical and radiologic outcomes in patients with anterior compressive cervical spondylosis and/or OPLL. OWC technique creates a more stable construct with 3-point fixation and offers better load sharing among implants and healthy vertebrae. Our observations suggest that OWC is a good surgical option for this patient group.

Comparative StudyDynamic evaluation of the spinal cord in patients with cervical spondylotic myelopathy using a kinematic magnetic resonance imaging technique.
This prospective study analyzed preoperative and postoperative dynamic changes of the spinal cord in patients with cervical spondylotic myelopathy. ⋯ Cord distances are relatively smaller at C4/5 and C5/6 levels, resulting in a narrowing of the posterior subarachnoid space with posterior cord compression in patients with cervical spondylotic myelopathy. The outcome of surgery was not correlated with the magnitude of postoperative backward shifting of the spinal cord, although the spinal cord of patients after posterior decompression moved significantly dorsally at any of the flexed, neutral, or extended spinal positions. Thus numerous factors might affect the postoperative outcomes.

Case ReportsTraumatic subacute spinal subdural hematoma successfully treated with lumbar drainage: case report.
A case report. ⋯ Traumatic spinal SDH is extremely rare and is usually associated with intracranial injury. Here, the authors report a rare case of traumatic spinal SDH not associated with head injury, which was successfully treated by lumbar drainage.
