Somatic Spinal Reflexes01:22

Somatic Spinal Reflexes

8.6K
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...

Muscles of the Forearm that Move the Hand and Fingers

3.4K
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...

Summary

Open extensor tendon injuries are common and can cause significant morbidity. Recent advances in repair and rehabilitation techniques offer improved outcomes for these hand injuries.

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Traumatology

Background:

  • Extensor tendons on the hand dorsum are superficial, leading to frequent open injuries.
  • These injuries range from simple lacerations to complex cases with significant tissue loss.
  • Historically, flexor tendon injuries received more focus, but extensor tendons are gaining research attention.

Purpose of the Study:

  • To summarize current treatment strategies for open extensor tendon injuries.
  • To highlight recent advancements in repair and rehabilitation protocols.
  • To provide an overview based on current literature.

Main Methods:

  • Review of recent scientific literature on open extensor tendon injuries.
  • Synthesis of information on modern surgical repair techniques.
Keywords:
