Anatomy

Upper Limb

Question 83 of 239

A 87 year old woman is brought in to the ED by her concerned family. They describe increasing swelling and tenderness of her right wrist. She is now febrile and you suspect septic arthritis. Which of the following synovial joint type best describes the wrist joint:

Answer:

The wrist joint is a synovial condyloid joint occurring between the distal end of the radius and the articular disc overlying the distal end of the ulna and the scaphoid, lunate and triquetrum.

Table: Anatomical Overview of the Wrist Joint

Joint Wrist joint
Type Synovial condyloid joint
Articulations Distal end of the radius and articular disc with scaphoid, lunate and triquetrum
Stabilising factors Joint capsule, palmar radiocarpal, palmar ulnocarpal and dorsal radiocarpal ligaments, radial and ulnar collateral ligaments of the wrist joint
Movements Flexion and extension, abduction and adduction

Articulations

The wrist joint is a synovial condyloid joint occurring between the distal end of the radius and the scaphoid, lunate and triquetrum. The ulna is prevented from articulating with the carpal bones by the presence of a fibrocartilaginous ligament, the articular disk. Instead, the ulna articulates with the radius just proximal to the wrist at the distal radioulnar joint.

Ligaments

The capsule of the wrist joint is reinforced by palmar radiocarpal, palmar ulnocarpal and dorsal radiocarpal ligaments. The radial and ulnar collateral ligaments of the wrist joint reinforce the medial and lateral sides of the wrist joint.

Movements

The wrist joint allows movement around two axes; the hand can be abducted and adducted, and flexed and extended at the wrist joint.

Table: Movements of the Wrist Joint

Movement Main Muscles Involved Main Nerves Involved
Flexion Flexor carpi radialis, flexor carpi ulnaris, flexor digitorum profundus, flexor digitorum superficialis, palmaris longus Median and ulnar nerves
Extension Extensor carpi radialis longus and brevis, extensor carpi ulnaris, extensor digitorum Radial nerve
Abduction Flexor carpi radialis, extensor carpi radialis longus and brevis Median and radial nerves
Adduction Flexor carpi ulnaris, extensor carpi ulnaris Ulnar and radial nerves
