Spinal Surgery

Patients in the restricted group were older and had higher rates of diabetes and hypertension than those in the unrestricted group, indicating a more comorbid population. For upper cervical decompression, a shift from the transoral to the endonasal endoscopic approach reduced tissue invasiveness and SSI rates. Fused segments are said to reduce movement-based signaling from receptors in joints and muscles. The article argues that fusion removes motion that previously generated signals to the brain. SSI risk can differ based on number of levels, surgical approach (anterior, lateral, or posterior), invasiveness (open vs minimally invasive), and underlying pathology (degenerative vs oncologic). Patients undergoing instrumented fusion had significantly increased odds of SSI (OR 3.30). The article states that signal deprivation after fusion can degrade brain regulation of the affected region over time. The final study cohort comprised 58,829 adult patients who underwent elective spinal surgery during the seventh, eighth, and ninth QA waves. Spinal surgery is described as often involving fusion of vertebral segments to stabilize them and prevent motion.
