Injuries of the Extensor Tendons of the Hand and Forearm
Summary
Extensor tendon injuries in the upper extremity require varied treatments based on injury zone. Prompt diagnosis and appropriate management, from splinting to surgical repair, are crucial for optimal outcomes.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Hand Surgery
Background:
- Extensor tendon injuries are frequent after trauma.
- These injuries can lead to significant upper extremity weakness.
- Treatment strategies vary widely based on injury severity and location.
Purpose of the Study:
- To outline the distinct treatment approaches for extensor tendon injuries.
- To correlate treatment methods with specific anatomical zones of injury.
- To emphasize the importance of zone-specific management for functional recovery.
Main Methods:
- Review of established treatment protocols for extensor tendon injuries.
- Classification of injuries based on anatomical zones (I-VI) of the upper extremity.
- Correlation of injury characteristics with recommended nonoperative and operative interventions.
Main Results:
- Zone I: Nonoperative treatment with potential pinning for avulsion fragments.
- Zone II & IV: Surgical repair with 6-week extension splinting recommended.
- Zone III: Closed extension splinting; Zone V: Delayed repair/reconstruction for bite wounds; Zone VI & proximal: Direct repair and immobilization.
Conclusions:
- Treatment of extensor tendon injuries is highly dependent on the specific anatomical zone.
- Nonoperative management is suitable for certain zones (e.g., Zone III), while others necessitate surgical intervention.
- Timely and zone-appropriate treatment is essential for restoring function and preventing long-term weakness.

Muscles of the Forearm that Move the Hand and Fingers
758
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...

Muscles that Move the Forearm
1.1K
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...

Bones of the Upper Limb: Ulna
1.9K
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: Humerus
2.7K
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...

Spinal Nerves: Plexus I
548
Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

Bones of the Upper Limb: Radius
1.9K
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.
The radius has a nail-shaped head, and a...
