Bones of the Upper Limb: Radius01:09

Bones 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.
The radius has a nail-shaped head, and a...

Fractures: Bone Repair

3.5K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

2.4K
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...

Muscles of the Forearm that Move the Hand and Fingers01:17

Muscles of the Forearm that Move the Hand and Fingers

1.2K
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

Summary
This summary is machine-generated.

Flexor tendon rupture after volar plate fixation for distal radius fractures is common, but patient age and radiographic factors like tilt and alignment do not predict rupture timing. Further research is needed to understand rupture causes.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering
  • Radiology

Background:

  • Flexor tendon rupture is a known complication following volar plate fixation of distal radius fractures.
  • Understanding factors influencing the timing of rupture is crucial for patient management and implant design.

Purpose of the Study:

  • To identify patient and radiographic factors correlating with the time to flexor tendon rupture after volar plate fixation.
  • To analyze the relationship between volar tilt, carpal alignment, and age with the interval to tendon rupture.

Main Methods:

  • Retrospective analysis of 31 patients who underwent volar plate removal due to flexor tendon rupture.
  • Radiographic measurements included volar tilt and lateral carpal alignment.
  • Volar plate prominence was graded using the Soong classification.

Main Results:

  • No correlation was found between the time to tendon rupture and the degree of volar tilt, carpal alignment, or patient age.
  • Volar plate prominence (Soong grade 1 or 2) was present in all cases of flexor tendon rupture.

Conclusions:

  • Radiographic parameters and patient age do not predict the time to flexor tendon rupture after volar plate fixation.
  • Volar plate prominence is a consistent finding in these ruptures, but its specific degree or associated radiographic measurements do not correlate with rupture timing.
