Comparative StudyComparison of isocentric C-arm 3-dimensional navigation and conventional fluoroscopy for C1 lateral mass and C2 pedicle screw placement for atlantoaxial instability.
A retrospective study. ⋯ On comparing the 2 imaging techniques, it was found that using Iso-C 3D navigation can significantly improve the accuracy of screw placement and decrease intraoperative fluoroscopic time and blood loss. This study demonstrates that Iso-C 3D navigation is a safe and effective means of guiding C1LM-C2P screw fixation for atlantoaxial instability.

Modified double-door laminoplasty in managing multilevel cervical spondylotic myelopathy: surgical outcome in 520 patients and technique description.
This is a prospective study on surgical outcomes of double-door laminoplasty in patients with cervical spondylotic myelopathy (CSM). ⋯ Modified double-door laminoplasty is a safe, reliable, and effective procedure for patients with CSM.

Mid-term follow-up of clinical and radiologic outcomes in cervical total disk replacement (Mobi-C): incidence of heterotopic ossification and risk factors.
Cervical arthroplasty has been shown to have successful, short-term and long-term radiologic and clinical outcomes. The incidence of and predisposing factors for heterotopic ossification (HO) have not been determined. We retrospectively assessed the intermediate-term clinical and radiologic outcomes, especially the incidence of HO and its risk factors. ⋯ Intermediate follow-up of cervical arthroplasty showed good clinical outcomes, although there was a trend toward reduction in alignment and motion at 24 months. The overall HO occurrence was 94.1% at 24 months. In our study, the most important factor affecting HO was the different surgical techniques.

Percutaneous posterior instrumentation followed by direct lateral interbody fusion for lumbar infectious spondylitis.
Retrospective study. ⋯ Minimally invasive PPI followed by debridement and DLIF was a feasible surgical alternative in our consecutive 16 cases of pyogenic spondylitis. In most cases, however the subsidence of anteriorly grafted fusion was inevitable despite successful fusion and eradication of the primary lesion.
