Unilateral Dual‐Plane Puncture Percutaneous Vertebroplasty Reduces Re‐Collapse in Osteoporotic Vertebral Compression Fractures by Advancing Cement Delivery

Orthopaedic Surgery, Volume 17, Issue 5, Page 1322-1331, May 2025.
Trajectory of the unilateral dual‐plane puncture. The sagittal CT scan after surgery clearly shows the puncture trajectory of the unilateral dual‐plane puncture. The bone cement simultaneously contacted both the upper and lower end plates. ABSTRACT Purpose Evaluate the efficacy of a novel unilateral dual‐plane puncture technique in improving bone ...

A Neural Network Model for Intelligent Classification of Distal Radius Fractures Using Statistical Shape Model Extraction Features

Orthopaedic Surgery, Volume 17, Issue 5, Page 1513-1524, May 2025.
This study developed an automated distal radius fracture classification system based on statistical shape model (SSM) feature extraction and neural network classification. The method first extracts point cloud data from CT images, then extracts fracture features through registration, downsampling, and PCA dimensionality reduction, before inputting them

Efficient multiple‐robust estimation for nonresponse data under informative sampling

Scandinavian Journal of Statistics, EarlyView.
Abstract Nonresponse in probability sampling presents a long‐standing challenge in survey sampling, often necessitating simultaneous adjustments to address sampling and selection biases. We develop a statistical framework that explicitly models sampling weights as random variables and establish the semiparametric efficiency bound for the parameter of ...

Effect of artificial gravity on calcaneal bone marrow adipose tissue and mineral content in female and male participants in 60 days of bed rest

Experimental Physiology, EarlyView.
Abstract Modulation of bone marrow adipose tissue (BMAT) with prolonged inactivity was reported in haemopoietic but not in non‐haemopoietic bones. This prospective randomized controlled trial submitted 16 men and 8 women to 60 days of 6° head‐down‐tilt bed rest.

50% body weight loading reduces stature increases and lumbar disc expansion from 4 h hyper‐buoyancy floatation versus 15 min sitting upright

Experimental Physiology, EarlyView.
Abstract Microgravity is associated with stature increases, back pain and post‐flight intervertebral disc (IVD) herniation. This study aims to determine whether 30 s seated 50% body weight (BW) axial loading is comparable to 15 min sitting upright in 1 g upon changes in stature, anterior lumbar IVD height (via ultrasound), passive vertebral stiffness ...
