Spine
-
A descriptive cadaveric study. ⋯ The presence of both synoviocytes and chondrocytes has been recorded in the present study, suggesting that the uncovertebral interface is synovial in nature. Immunoreactivity to PGP 9.5, SP, CGRP, and NPY indicates the presence of nerve fibers from both the somatic and autonomic nervous systems. These findings suggest that the uncovertebral joints are potential pain generators in the cervical spine.

A case-control study of older adults with and without chronic low back pain (CLBP). ⋯ From a research perspective, radiographic evaluation of spinal pathology provides additional information about older adults with CLBP compared to pain-free individuals, but its clinical utility for diagnostic purposes is still in question.

Randomized Controlled Trial Comparative Study
A prospective randomized study of clinical outcomes in patients with cervical compressive myelopathy treated with open-door or French-door laminoplasty.
A prospective randomized clinical study. ⋯ Perioperative complications occurred more frequently in open-door laminoplasty than in French-door laminoplasty. JOA scores and recovery rates suggested that both open-door and French-door laminoplasties could be similarly effective in decompressing the spinal cord. Axial pain was improved in French-door laminoplasty but became worse in open-door laminoplasty. SF-36 suggested that French-door laminoplasty could be more beneficial than open-door laminoplasty for patients with cervical compressive myelopathy.

The risk for transection of the medial branch nerve (MBN) after minimally invasive insertion of pedicle screws was evaluated in a human cadaver model. ⋯ Using a percutaneous technique for pedicle screw insertion significantly reduces the risk of injury to the MBN. We therefore recommend using this technique especially at the most cephalic levels to minimize the risk of denervating the multifidus muscle fascicles that originate from the adjacent mobile level.

Comparative Study
Comparison of selective anterior versus posterior screw instrumentation in Lenke5C adolescent idiopathic scoliosis.
Retrospective review of anterior and posterior fusions for treatment of Lenke5C adolescent idiopathic scoliosis (AIS). ⋯ Selective anterior and posterior screw instrumentation both achieved good surgical lumbar and subsequent spontaneous thoracic correction. There was no statistically significant difference between the 2 groups in lumbar correction or thoracic correction, but fusion levels were shorter in the anterior group. Patients with late thoracic curve decompensation had smaller thoracolumbar/lumbar-thoracic Cobb ratios and less preoperative flexibility than those who did not decompensate.
