To compare the clinical and radiological outcomes of posterior atlantoaxial fixation and fusion using C1 lateral mass-C2 pedicle screws (screw-rod constructs, SRC) with C1-C2 transarticular screws (TAS). ⋯ Both SRC and TAS produced excellent outcomes for atlantoaxial stabilization. But the volume of bleeding and operation time tended to be better in TAS group compared to SRC group.

The generation and tissue origination of disc-associated axial pain is still under exploration. This study was performed to evaluate disc-associated axial pain and to explore whether it originates in the disc or its surrounding components. ⋯ Preoperative axial pain due to single-level disc protrusion was triggered and aggravated only during PLL resection and disappeared postoperatively. This implies that the intervertebral PLL could be the site of origination of axial pain. Axial pain from the PLL at different disc levels had different distributions.

Review Meta Analysis Comparative Study
Zero-profile anchored cage reduces risk of postoperative dysphagia compared with cage with plate fixation after anterior cervical discectomy and fusion.
To compare the rate of postoperative dysphagia between zero-profile anchored cage fixation (ZPC group) and cage with plate fixation (CP group) after anterior cervical discectomy and fusion (ACDF). ⋯ Zero-profile anchored cage had a lower risk of postoperative dysphagia than cage with plate.

The purpose of this study was to assess long-term follow-up data after anterior cervical decompression and fusion (ACDF) with and without Caspar plating (ACDF + PS) for the treatment of cervical spondylotic myelopathy (CSM) with special focus on functional outcome, pain, and repeat surgery for adjacent segment disease (ASD). ⋯ ACDF and ACDF + PS yield significant decrease in neck pain, a significant increase in sensorimotor function and a high rate of clinical success. Patients with preoperative gait disturbance completely recovered in about 60% of cases. Overall prevalence for ASD was 17.4% after 25 years.

A fresh frozen cadaver study was conducted. ⋯ The dynamic surgical guidance probe is a safe tool to assist the surgeon with screw placement in the cervical spine. Additionally, the DSG potentially avoids the cumulative risks associated with fluoroscopy and provides real-time feedback to the surgeon allowing correction at the time of breach. Level of evidence Level IV.
