Summary
Radiographers can use measured radial inclination (RI) to guide tube angulation for anatomical tilt lateral (ATL) wrist X-rays. This improves accuracy and reduces patient radiation exposure from repeat imaging.
Area of Science:
- Orthopedic Surgery
- Radiology
- Medical Imaging
Background:
- Open Reduction and Internal Fixation (ORIF) is common for distal radial fractures.
- Anatomical tilt lateral (ATL) wrist X-rays are crucial for assessing screw penetration.
- Accurate screw placement evaluation depends on precise radiographic technique.
Purpose of the Study:
- To investigate the correlation between radiographer-applied tube angulation for ATL projections and measured radial inclination (RI) on PA wrist images.
- To determine if RI measurements can inform ATL projection technique.
Main Methods:
- Retrospective review of 36 patients' X-ray images.
- Standardized measurement of RI on Posterior Anterior (PA) wrist images.
- Analysis of annotated tube angulation on ATL images using Pearson's correlation.
Main Results:
- A strong positive correlation (p=0.792) was found between applied tube angulation and measured RI.
- The average RI measured was 19 degrees.
Conclusions:
- Radiographers can utilize measured RI to determine optimal tube angulation for ATL wrist X-rays.
- This approach offers a more reliable and reproducible method for image acquisition.
- Implementing this technique can decrease repeat imaging and patient radiation dose.

01:15Bones of the Upper Limb: Ulna
2.3K
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...

01:09Bones of the Upper Limb: Radius
2.3K
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.

01:11Anatomical Positions
10.4K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

01:19Bones of the Upper Limb: Humerus
3.4K
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...

00:51Anatomical Movements
7.3K
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...

01:28Articulations of the Vertebral Column
2.0K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...
