Objective: Postural abnormalities are a debilitating symptom of Parkinson disease (PD) that may require spinal intervention. Camptocormia is a unique abnormality most seen in PD, defined by a severe forward flexion of the trunk that completely resolves when supine. The condition presents a challenge due to an undefined pathophysiology and optimal therapeutic approach in a high-risk patient population. In this study, we systematically reviewed the literature regarding the use of spine surgery for the treatment of camptocormia in PD.
Methods: PubMed, Embase, Web of Science, and Cochrane Library were systematically queried for studies involving spine surgery as treatment of PD-associated camptocormia. Studies involving nonsurgical management, involving deep brain stimulation, involving noncamptocormic PD patients undergoing surgery, or were out of scope were excluded.
Results: The search resulted in 5 studies, with a total of 19 patients with PD with camptocormia who underwent spine surgery (73.7% women). The mean age was 69.5 years (range, 59-83), and the mean PD duration was 69.5 months (range, 36-84). Of 19 patients, 11 required surgical revision (57.9%), with an average of 0.68 revisions per patient (range, 0-2). Radiographic and patient-reported outcomes were inconsistently reported yet showed improvement. Ultimately, 18 patients were reported to have positive outcomes.
Conclusions: Despite an increased risk of complication and revision that is inherent to patients with PD, spine surgery has been proven as a reasonable alternative that should be prospectively studied further because 18 of 19 patients had favorable outcomes.

Background: Research has demonstrated that individuals with sarcopenia or sarcopenic obesity who experience fractures or undergo major surgical interventions exhibit a poorer prognosis compared to the general population. However, few studies have investigated the relationship between the skeletal muscle and adipose tissue indices, as measured at the 12th thoracic spine level, and adverse outcomes following orthopedic surgery. Therefore, this study aimed to prove whether skeletal muscle and adipose tissue index measured by computed tomography (CT) images based on a single layer are associated with one-year postoperative mortality in elderly hip fracture patients.

Background: Perioperative neurocognitive disorder (PND) is a prevalent form of cognitive impairment in elderly patients following anesthesia and surgery. The underlying mechanisms of PND are closely related to perineuronal nets (PNNs). PNNs, which are complexes of extracellular matrix primarily surrounding neurons in the hippocampus, play a critical role in neurocognitive function.

Background: Spinal epidural arachnoid cysts (SEACs) are rare, non-neoplastic pathologies that can cause compressive myelopathy. Preoperative identification of the exact fistula location is crucial for minimally invasive management.
Methods: This single-center retrospective study included 27 patients with SEACs who underwent "double-needle puncture myelography" to precisely localize the fistula before minimally invasive surgery.

Surgical site infections (SSIs) are a significant concern following posterior lumbar fusion surgery, leading to increased morbidity and healthcare costs. Accurate prediction of SSI risk is crucial for implementing preventive measures and improving patient outcomes. This study aimed to construct and validate a nomogram predictive model for assessing the risk of SSIs following posterior lumbar fusion surgery.

Introduction: Recurrent lumbar disc herniation (rLDH) remains a challenge in spinal surgery. This systematic review analyzes the use of transforaminal endoscopic discectomy (TFED) for the treatment of rLDH.
Methods: A comprehensive search of 4 electronic databases, including PubMed, Google Scholar, Science Direct, and Cochrane, was conducted.
