Two-stage spinal osteotomy combined with lateral lumbar interbody fusion for lumbar kyphosis: illustrative case.
J Neurosurg Case Lessons
December 2024
Department of Orthopaedic Surgery, University of Toyama, Toyama City, Toyama, Japan.
Background: Adult spinal reconstructive surgery that requires multilevel spinal fusion is highly invasive and requires two-stage surgery using lateral lumbar interbody fusion (LLIF) and/or percutaneous pedicle screw (PPS) fixation to make it less invasive. However, it is still difficult to make spinal osteotomy less invasive, and the high complication rate is an issue.
Observations: The authors present the surgical techniques of a two-stage Schwab grade 4 spinal osteotomy using LLIF, which could reduce surgical invasiveness and enable good correction and anterior spinal column reconstruction for lumbar kyphosis, and also report a case treated with this procedure.
Subchronic cyanuric acid treatment impairs spatial flexible behavior in female adolescent rats through depressing GluN2B-dependent neuronal and synaptic function.

Subchronic exposure to cyanuric acid (CA) and its structural analogue melamine induces long-term effects on brain and behavior in male rodents. To examine if this exposure induced negative effects on cognitive function in females, we examined the behavioral performance and further attempted to investigate synaptic and neuronal function. CA was intraperitoneal treated with 20 or 40 mg/kg/day to adolescent female rats for 4 consecutive weeks.

Cerebral autoregulation (CA) is the mechanism that maintains stable cerebral blood flow (CBF) despite fluctuations in systemic blood pressure, crucial for brain homeostasis. Recent evidence highlights distinct regional variations in CA between the anterior (carotid) and posterior (vertebrobasilar) circulations. Non-invasive neuromonitoring techniques, such as transcranial Doppler, transfer function analysis, and near-infrared spectroscopy, facilitate the dynamic assessment of CBF and autoregulation.

Article Synopsis
- Vertebral arterial injury (VAI) can be a serious complication after C1-C2 posterior screw fixation, as observed in a case of a 34-year-old woman with quadriplegia who suffered bilateral VAI caused by her surgical screws.
- Postoperative imaging revealed that the screws had violated the vertebral arteries but did not result in any neurological deterioration or infarction.
- The case highlights the importance of careful screw placement to prevent VAI during surgery, as well as the potential for variations in blood circulation to impact patient outcomes.
Atypical Multi-ligamentous Knee Injury (MLKI): Binary Injury with Avulsion of One Cruciate and Tear of the Other, or Bi-cruciates Avulsion with or Without Collateral Ligament Injury Following Road Traffic Accidents (RTA).

Department of Orthopaedics and Spine Surgery, Ganga Medical Center & Hospital, Coimbatore, India.
Background: Multi-ligamentous knee injuries (MLKI) fall within a narrow spectrum, accounting for around 11% of all knee injuries. Atypical MLKI involve binary injury: avulsion of one cruciate and tear of the other, or both cruciates avulsion with or without collateral ligament injury.
Purpose: The purpose of this study is to analyse the clinical and radiological outcomes of patients diagnosed with atypical MLKI, and to assess the differences in outcomes between patients with collateral injury and those without.
