Granulomatous reaction on a double-level cervical total disc arthroplasty : case report.
Cervical total disc arthroplasty (TDA), or cervical artificial disc replacement, is an alternative technique to anterior cervical discectomy and fusion for treatment of symptomatic degenerative cervical spine disease. The main goal of TDA is to maintain cervical motion and lower the risk of deterioration of adjacent levels. Granuloma formation on a cervical TDA is exceptional. ⋯ We report a third case of granulomatous reaction on nylon thread extrusion after partial breakdown of a prosthesis for cervical TDA.

Indocyanine green videoangiography (ICG-V) is used with increasing frequency in neurovascular surgery. ICG-V use in spinal dural arteriovenous fistulas (DAVFs) allows visualization of the hemodynamics of the fistula and to confirm its exclusion after ligation of the feeder. Here, we illustrate how ICG-V is useful for centering the surgical exposure during mini-invasive approaches to spinal DAVFs. ⋯ IGC-V can be helpful in mini-invasive approaches to spinal DAVFs to recalibrate the bone opening after misplacement of the initial hemilaminectomy.

Deep Brain Stimulation of Nucleus Accumbens for Methamphetamine Addiction: Two Case Reports.
Methamphetamine (MA) addiction is one of the most prevalent socioeconomic and health problems worldwide. In recent years, deep brain stimulation (DBS) has increasingly been used for the treatment of addiction. ⋯ These case reports demonstrate that NAc-DBS maybe a possible treatment option for MA addiction.

We retrospectively analyzed and report the clinical results of percutaneous endoscopic lumbar discectomy (PELD) in treating patients with calcified lumbar intervertebral disc herniation (CLDH). ⋯ With the application of Peak philosophy, PELD is safe and effective in treating patients with CLDH. The use of PELD results in good neurological recovery, pain relief, and a low incidence of complications.

Case Reports
Delayed recurrent laryngeal nerve palsy following anterior cervical discectomy and fusion: A case report.
Vocal cord dysfunction resulting from recurrent laryngeal nerve palsy (RLNP) is a known complication following anterior cervical discectomy and fusion. RLNP occurs typically secondary to neurapraxia caused by intraoperative compression or traction on the nerve and less commonly from direct nerve injury intraoperatively in the setting of anterior cervical spine surgery. Patients with RLNP typically present with hoarseness immediately after surgery owing to unilateral vocal cord paralysis. In rare cases, there is late-onset, progressive development of RLNP that may potentially lead to permanent vocal cord paralysis or respiratory failure. ⋯ To our knowledge, this is the first report of delayed RLNP in patients undergoing anterior cervical discectomy and fusion. This rare complication should be discussed during preoperative patient counseling. Previous literature indicates the underlying pathophysiology for delayed onset of RLNP may be small vessel ischemia, vasospasm, or viral resurgence that leads to recurrent laryngeal nerve dysfunction.
