Wrist

The wrist is a highly complex and versatile joint that plays a crucial role in hand movement and function. This article provides an exhaustive overview of the wrist, including its anatomy, functions, common problems, diagnostic methods, treatments, preventive measures, and lifestyle tips to maintain healthy wrists.

‍

Bony Structure

The wrist is composed of eight small bones, known as the carpal bones, arranged in two rows. These bones connect the hand to the forearm and allow for a wide range of motion.

• Proximal Row: Includes the scaphoid, lunate, triquetrum, and pisiform bones.
• Distal Row: Includes the trapezium, trapezoid, capitate, and hamate bones.

The carpal bones articulate with the radius and ulna (forearm bones) to form the wrist joint. The distal ends of the radius and ulna create a concave surface that accommodates the convex surfaces of the carpal bones.

Muscular Structure

The muscles of the wrist are essential for movement and stability. They can be divided into extrinsic and intrinsic muscles.

• Extrinsic Muscles: These muscles originate in the forearm and insert into the hand and wrist. They include:some text
  • Flexor Carpi Radialis and Flexor Carpi Ulnaris: Responsible for wrist flexion.
  • Extensor Carpi Radialis Longus and Brevis, and Extensor Carpi Ulnaris: Responsible for wrist extension.
• Intrinsic Muscles: These muscles are located entirely within the hand and wrist, contributing to fine motor movements.

Ligamentous and Nervous Structure

The wrist is supported by several ligaments and innervated by nerves that ensure stability and function.

• Ligaments:some text
  • Palmar Radiocarpal Ligament: Stabilizes the wrist joint on the palmar side.
  • Dorsal Radiocarpal Ligament: Stabilizes the wrist joint on the dorsal side.
  • Ulnar Collateral Ligament: Stabilizes the ulnar side of the wrist.
  • Radial Collateral Ligament: Stabilizes the radial side of the wrist.
• Nerves:some text
  • Median Nerve: Provides sensation to the palmar side of the thumb, index finger, middle finger, and half of the ring finger.
  • Ulnar Nerve: Provides sensation to the palmar and dorsal sides of the little finger and half of the ring finger.
  • Radial Nerve: Provides sensation to the dorsal side of the thumb, index finger, and middle finger.
