Biomechanical analysis of posteromedial tibial plateau fracture fixation in fresh cadaveric bone.

This study aims to compare the mechanical strength of three different posterior-based internal fixation methods for posteromedial tibial plateau fractures. The study utilized 12 tibial plateaus harvested from fresh-frozen cadavers, and the posteromedial fracture fragments were created. The bones were then randomly assigned to one of three fixation methods: two posteroanterior lag screws (LS) size 4.

Artificial intelligence (AI) vs. human in hip fracture detection.

Objective: This study aimed to assess the diagnostic accuracy and sensitivity of a YOLOv4-tiny AI model for detecting and classifying hip fractures types.

Materials And Methods: In this retrospective study, a dataset of 1000 hip and pelvic radiographs was divided into a training set consisting of 450 fracture and 450 normal images (900 images total) and a testing set consisting of 50 fracture and 50 normal images (100 images total). The training set images were each manually augmented with a bounding box drawn around each hip, and each bounding box was manually labeled either (1) normal, (2) femoral neck fracture, (3) intertrochanteric fracture, or (4) subtrochanteric fracture.

Bone metastasis from cholangiocarcinoma mimicking osteosarcoma: A case report and review literature.

Cholangiocarcinoma is an aggressive tumor of the hepatic biliary system and it commonly spreads to the regional lymph nodes, liver and lungs. However, bone metastasis from cholangiocarcinoma is rare compared with other tumors. We herein present the case of a 61-year-old Asian woman who presented with pain in the right scapular area.
