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

Muscles of the Forearm that Move the Hand and Fingers

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 radialis,...
Muscles of the Leg that Move the Foot and Toes01:28

Muscles of the Leg that Move the Foot and Toes

The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.
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...
Somatic Spinal Reflexes01:22

Somatic Spinal Reflexes

Somatic spinal reflexes are rapid, involuntary muscular responses to external stimuli that involve the somatic musculature and the spinal cord.
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...
Ankle Joint01:10

Ankle Joint

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...
Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

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 short...

Summary
This summary is machine-generated.

Mallet injuries and flexor digitorum profundus (FDP) ruptures are common athletic tendon injuries. Treatment varies, with mallet injuries managed non-surgically or surgically, while FDP ruptures typically require surgery.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Hand Surgery

Background:

  • Mallet injuries represent the most frequent closed tendon injury in athletes.
  • Flexor digitorum profundus (FDP) ruptures, though rare in baseball, are prevalent in contact sports.

Purpose of the Study:

  • To outline the diagnostic and treatment considerations for mallet injuries and FDP ruptures in athletes.
  • To differentiate management strategies based on injury type and athlete goals.

Main Methods:

  • Diagnosis relies on clinical examination.
  • Radiographs are utilized to identify potential bony involvement.
  • Treatment decisions are individualized based on athlete's competitive objectives and understanding of treatment implications.

Main Results:

  • Mallet injury treatment is contingent upon the athlete's goals and acceptance of potential functional limitations.
  • Immobilization for mallet injuries can impede gripping, throwing, and catching.
  • FDP ruptures necessitate surgical intervention for tendon reattachment to the distal phalanx.

Conclusions:

  • Effective management of mallet injuries and FDP ruptures requires accurate diagnosis and tailored treatment plans.
  • Understanding the functional impact of treatment options is crucial for athletes.
  • Surgical repair is the standard for FDP ruptures, while mallet injury treatment is more variable.
