Paralysis subsequent to spinal cord decompression in the cervical or thoracic region is infrequent, with White Cord Syndrome (WCS) being among its several causes. Due to WCS's infrequency, there exists a paucity of high-level evidence concerning its manifestations. Our primary objective is to systematically collate all documented WCS cases, discern prevalent risk and prognostic factors, appraise available treatment modalities, and evaluate patient outcomes. ⋯ WCS is a rare cause of postoperative neurological deficit following spinal cord decompression surgery. Risk factors for WCS include advanced age, extensive surgery, posterior approach for decompression, and the presence of OPLL. Treatment includes high-dose steroids, posterior cervical decompression, maintaining MAP over 85mmHg, rehabilitation, and sometimes neurotrophic drugs. Most patients can walk with or without assistance during follow-up, but around a quarter never regain neurological function. The only preoperative factor impacting outcomes is the preoperative neurological status (Nurick Grade).

Short-term efficacy of percutaneous kyphoplasty (PKP) for treating osteoporotic vertebral compression fracture (OVCF) in elderly patients is good, but long-term complications such as vertebral recompression (VRC) and adjacent vertebral fracture (AVF) may arise. Identifying risk factors in patients with poor prognoses, we developed a nomogram model to mitigate these potential complications. ⋯ This study identified four independent predictors of poor prognosis following PKP and devised a straightforward yet efficient predictive model. This model offers valuable insights for guiding clinical decision-making in the management of elderly patients with OVCFs.

Multicenter Study
Morphometric analysis of atlas lateral mass in Down syndrome cases with relevance to surgical intervention.
Surgical stabilization of the Atlas vertebrae is indicated for severe atlantoaxial instability (AAI) in patients with Down syndrome (DS). This study aims to evaluate the morphological characteristics of the Atlas lateral mass (ALM) in patients with DS with regard to safe instrumentation for surgical stabilization and to compare them with non-syndromic group. ⋯ Patients with DS had a smaller posterior ALM wall and a steeper arch-ALM angle than the control group without DS. This information is important for surgical planning of safe posterior ALM exposure and safe instrumentation for surgical stabilization in patients with DS.

Comparative Study
What is the early fate of adjacent segmental lordosis compensation at L3-4 and L5-S1 following a lateral versus transforaminal lumbar Interbody Fusion at L4-5?
Degenerative spondylolisthesis causes translational and angular malalignment, resulting in a loss of segmental lordosis. This leads to compensatory adjustments in adjacent levels to maintain balance. Lateral lumbar interbody fusion (LLIF) and transforaminal lumbar interbody fusion (TLIF) are common techniques at L4-5. This study compares compensatory changes at adjacent L3-4 and L5-S1 levels six months post LLIF versus TLIF for grade 1 degenerative spondylolisthesis at L4-5. ⋯ LLIF at L4-5 increases lordosis at the operated level, with compensatory decrease at L5-S1 but not L3-4. This reciprocal loss at adjacent L5-S1 may explain inconsistent improvement in lumbar lordosis (PI-LL) post L4-5 fusion.
