Summary
This study details a rare first extensor compartment tendon injury at the myotendinous junction following radial styloid and forearm fractures. A novel surgical repair technique and proposed rupture mechanism are presented for this specific injury.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Hand Surgery
Background:
- Fractures of the radial styloid and both-bone forearm are common orthopedic injuries.
- Injuries to the extensor tendon compartments, particularly the first dorsal compartment, are less frequently associated with these fractures.
Observation:
- A rare case of first extensor compartment tendon injury occurred at the myotendinous junction in a healthy 59-year-old male post-fracture.
- The injury involved the abductor pollicis longus and extensor pollicis brevis tendons.
Findings:
- A novel surgical technique for repairing this specific myotendinous junction injury was successfully employed.
- A new mechanism contributing to tendon rupture in this context is proposed, highlighting the biomechanical stress.
Implications:
- Clinicians should maintain a high suspicion for first dorsal compartment tendon rupture in patients with radial styloid and both-bone forearm fractures.
- The described tubularization and tendon transfer technique, utilizing abductor pollicis longus and extensor pollicis brevis to the brachioradialis, may offer a beneficial reconstructive option.

01:09Bones of the Upper Limb: Radius
3.9K
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.

01:15Bones of the Upper Limb: Ulna
3.5K
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...

01:19Bones of the Upper Limb: Humerus
6.0K
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...

01:16Muscles that Move the Forearm
3.0K
The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...

01:27Fractures: Bone Repair
4.2K
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...

01:17Muscles of the Forearm that Move the Hand and Fingers
1.8K
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...
