Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

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...
Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

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 of the...
Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
Muscles that Move the Forearm01:16

Muscles that Move the Forearm

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...
Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
Muscles that Move the Arm01:31

Muscles that Move the Arm

Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

Summary

Elbow dislocations in athletes are common, but treatment guidelines are unclear. Early range of motion exercises after brief immobilization can speed return to sports within six weeks.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Rehabilitation Science

Background:

  • Elbow dislocations are frequent injuries among athletes.
  • Current treatment protocols lack clear guidelines, often relying on general population data.
  • This gap necessitates specific evidence-based recommendations for athletic elbow injuries.

Purpose of the Study:

  • To review current literature on elbow dislocation treatment in athletes.
  • To propose an evidence-based approach for managing athletic elbow dislocations.
  • To determine optimal rehabilitation strategies for timely return to sport.

Main Methods:

  • Literature review of studies on elbow dislocations in athletic individuals.
  • Analysis of treatment outcomes, including immobilization duration and rehabilitation protocols.

Related Experiment Videos

  • Evaluation of factors influencing return to sports participation timelines.

    • Main Results:

    • A short immobilization period followed by early range of motion exercises is effective.
    • This approach was shown to limit disability and facilitate a return to athletic activities.
    • Athletes can typically resume sports participation within approximately six weeks.

    Conclusions:

    • Early mobilization and targeted exercises are crucial for athletes with elbow dislocations.
    • This strategy minimizes recovery time and functional deficits.
    • Standardized treatment guidelines for athletic elbow injuries should be established based on these findings.
