Muscles of the Forearm that Move the Hand and Fingers01:16

Muscles of the Forearm that Move the Hand and Fingers

2.9K
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...

Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

10.7K
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...

Ankle Joint01:10

Ankle Joint

3.4K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Work Done Over an Inclined Plane

4.1K
The center-of-mass framework helps to easily describe the work done on rigid bodies. Since the internal forces in a rigid body do no work, they can be ignored, and the external forces can be considered in the work-energy theorem.
The work done by gravity to move a rigid body, or the work done by an opposing force to move a rigid body against gravity, can be calculated using the center-of-mass framework. It is the line integral of the force of gravity over the path, considered positive if...

Knee Joint01:23

Knee Joint

3.6K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

10.4K
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...

    Area of Science:

    • Orthopedics
    • Sports Medicine
    • Hand Surgery

    Background:

    • Skier's thumb is a frequent injury among athletes.
    • It involves damage to the ulnar collateral ligament (UCL) at the thumb's base.
    • Accurate diagnosis is crucial for effective treatment and recovery.

    Purpose of the Study:

    • To outline the diagnostic methods for skier's thumb.
    • To describe treatment strategies based on injury severity.
    • To discuss expected outcomes and rehabilitation for athletes.

    Main Methods:

    • Diagnosis relies on patient history and physical examination.
    • Key physical findings include point tenderness and ligament instability.
    • Instability is assessed with the thumb in neutral and flexed positions.

    Main Results:

    • Grade 1 and 2 injuries (ligament sprains) are managed non-surgically with casting/splinting and physical therapy.
    • Grade 3 injuries (complete tears) typically necessitate surgical repair.
    • Treatment outcomes are generally excellent, facilitating return to athletic activity.

    Conclusions:

    • Skier's thumb diagnosis is primarily clinical.
    • Non-operative and operative treatments yield successful outcomes.
    • Rehabilitation is key for athletes to regain function and return to sport.
