Bones of the Upper Limb: Ulna

Bones of the Upper Limb: Ulna

The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

Bones of the Upper Limb: Radius

Bones of the Upper Limb: Radius

The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

Bones of the Upper Limb: Humerus

Bones of the Upper Limb: Humerus

The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Statistical Software for Data Analysis and Clinical Trials

Statistical Software for Data Analysis and Clinical Trials

Statistical software is pivotal in data analysis and clinical trials by providing tools to analyze data, draw conclusions, and make predictions. These software packages range from simple data management applications to complex analytical platforms, supporting various statistical tests, models, and simulation techniques. Their significance lies in their ability to handle vast amounts of data with precision and efficiency, enabling researchers to validate hypotheses, identify trends, and make...

Area of Science:

Medical Imaging
Biomechanical Engineering
Computational Anatomy

Background:

Tridimensional scanning in medicine generates digital patient surfaces for anthropometric measurements and limb volume quantification.
Limited availability of free software hinders study reproducibility and the evaluation of alternative measurement techniques.
Reliance on proprietary software restricts data sharing and inter-center comparisons in medical research.

Purpose of the Study:

To introduce a novel, free software package designed for 3D medical imaging analysis.
To detail the software's functions for volume assessment and anthropometric measurement.
To evaluate the performance of digital volumes generated by the software, including the convex-hull gift-wrapping algorithm.

Main Methods:

Development and release of a three-program software package with supporting materials.
Introduction of volume assessment steps and upper limb quantification procedures.
Pilot study using the software on a small group of young adults to assess digital volume accuracy.

Main Results:

The software package demonstrated substantial agreement between clinical measurements and its digital volume configurations (R²: 0.93–0.97, r: 0.965–0.984).
The convex-hull gift-wrapping algorithm and other analysis methods within the software were validated.
Gender was identified as a potential influencing variable in upper limb volume quantification models.

Conclusions:

The developed free software package enhances reproducibility and comparability in medical imaging studies.
The software provides accurate limb volume quantification, supporting clinical and research applications.
Further research should consider factors like gender when developing generalized limb volume models.
