Anatomy of the Elbow Joint The three bones that are responsible for the formation of the elbow joint are humerus, radius and ulna. It includes two articulations: (a) humero-ulnar articulation, between the trochlea of the humerus and trochlear notch of the ulna, and (b) humero-radial articulation, between the capitulum of the humerus and the head [...]

Radio-Ulnar Joints

By Dr. Joseph H Volker | 2018-08-30T08:36:48+00:00 August 8th, 2018|Anatomy, Joints, Upper Limb|0 Comments

The Superior radio-ulnar joint and the Inferior radio-ulnar joint are the two joints formed between the radio and ulna. The Superior radio-ulnar joint is formed at the upper end, while the Inferior radio-ulnar joint is formed at the lower end of radius and ulna. Both these Radio-Ulnar Joints are synovial joints of pivot variety. Both [...]

Joints of The Digits

By Dr. Joseph H Volker | 2018-09-12T08:25:39+00:00 August 8th, 2018|Anatomy, Joints, Upper Limb|0 Comments

The joints of digits are: Metacarpophalangeal joints. Interphalangeal joints. Metacarpophalangeal (MP) Joints Type They're synovial joints of ellipsoid/condylar variety. Articular Surfaces They're created by heads of metacarpals and bases of proximal phalanges. Ligaments Palmar Ligaments The palmar ligament is a fibrocartilaginous plate, that is more firmly connected to the phalanx than to the [...]

Coracoclavicular Ligament

By Dr. Joseph H Volker | 2018-08-30T11:12:31+00:00 August 8th, 2018|Anatomy, Joints, Upper Limb|0 Comments

The coracoclavicular ligament is in fact two ligaments, the trapezoid and the conoid. The trapezoid and the conoid ligaments have identical dimensional, viscoelastic behavioral and structural characteristics, regardless of their morphologic differences. It plays an important function in sustaining the integrity of the joint however lies little far from the joint itself. Structure [...]

Coracohumeral ligament is a strong strap of fibrous tissue that enters from the base of the coracoid process to the anterior element of the greater tubercle of the humerus. Origin of Coracohumeral Ligament Coracohumeral ligament enters obliquely downwards and laterally to the front of the greater tubercle of the humerus, where the coracohumeral [...]

Coracoacromial Ligament

By Dr. Joseph H Volker | 2018-08-30T11:01:13+00:00 August 8th, 2018|Anatomy, Joints, Upper Limb|0 Comments

Coracoacromial ligament guards the superior aspect of the joint and develops within coracoid and acromion processes. The ligament is often illustrated as containing two marginal bands as well as a thinner intervening part, the two bands being connected specifically towards the apex along with the base of the coracoid process, and also merging at the [...]
