Anatomical Tibial Tunnel Vector in Pull-Out Repair for a Medial Meniscal Posterior Root Tear (MMPRT) and Its Clinical Potential.

Introduction This study focuses on the tibial tunnel in the pull-out repair of medial meniscus posterior root tears (MMPRTs), with attention to the distal hole as the anatomical vector. Little research has explored this aspect, as previous studies have mainly emphasized the proximal hole as the attachment point. Methods The anatomical vector was identified by analyzing magnetic resonance images of 84 healthy knees.

Estimated Blood Loss in Surgery for Thoracolumbar Fracture With Diffuse Idiopathic Skeletal Hyperostosis Using Percutaneous Pedicle Screws Compared to Surgery for Femoral Trochanteric Fractures.

Introduction: Long posterior spinal stabilization is often needed for thoracolumbar fractures with diffuse idiopathic skeletal hyperostosis (DISH). Recently, surgery using percutaneous pedicle screws (PPS) has become more frequent. However, hidden blood loss (HBL) cannot be ignored in surgeries using PPS.

Intratumoral Flow Void Diameter as a Predictor of High Intraoperative Blood Loss in Palliative Excisional Surgery for Metastatic Spinal Tumors.

Massive intraoperative blood loss (IBL) is one of the major complications in metastatic spinal tumor surgery (MSTS), and understanding the predictors of this risk is essential. This study aimed to determine the impact of the intratumoral flow void (IFV) observed on standard magnetic resonance imaging (MRI) and its association with IBL in palliative surgery for metastatic spinal tumors. This retrospective analysis included 88 palliative excisional surgeries performed at a single hospital between 2010 and 2024.
