Subscapular Spaces (Intermuscular Spaces In The Scapular Region)

By Dr. Joseph H Volker | 2018-08-30T10:45:20+00:00 August 8th, 2018|Anatomy, Areas, Upper Limb|0 Comments

Subscapular Spaces are (1) quadrangular and (2) triangular intermuscular spaces in the scapular region, that are clearly viewed from behind after reflecting the posterior part of the deltoid. The knowledge of subscapular spaces is necessary during surgery in the shoulder region. Quadrangular Space Boundaries Quadrangular subscapular spaces are bound by 4 sides which are as [...]

Olecranon Fossa

By Dr. Joseph H Volker | 2018-08-30T09:48:38+00:00 August 8th, 2018|Anatomy, Areas, Upper Limb|0 Comments

Olecranon fossa is a depression situated directly superior to trochlea, at the posterior part of the distal end of the humerus. The olecranon process of ulna fits into olecranon fossa during full extension of elbow. Olecranon fossa is the largest of all three fossae in the region. The capsule of elbow joint is connected above [...]

Radial Fossa

By Dr. Joseph H Volker | 2018-08-30T08:36:04+00:00 August 8th, 2018|Anatomy, Areas, Upper Limb|0 Comments

Radial fossa is an indentation above the capitulum and is found on the anterior surface of humerus. The head of radius fills the radial fossa at the time of extreme flexion of the elbow joint. At the lower end of humerus, the capitulum joins together with the upper curved in surface of the head of [...]

Head of the Humerus

By Dr. Joseph H Volker | 2018-08-30T09:05:25+00:00 August 8th, 2018|Anatomy, Areas, Upper Limb|0 Comments

The humerus, a.k.a. the upper arm bone is the largest and longest bone of the upper limb. It is a comparatively thick bone with a large, smooth head at the proximal end and a number of projections a.k.a. “process” at the distal end. Head of Humerus Proximal Humerus/Head The proximal end of the [...]

Coronoid Fossa

By Dr. Joseph H Volker | 2018-08-30T08:45:13+00:00 August 8th, 2018|Anatomy, Areas, Upper Limb|0 Comments

Coronoid fossa is an impression at the lower end of humerus just above the trochlea. The coronoid process of ulna covers the coronoid fossa of humerus while flexion. At the lower end of humerus, the trochlear notch of ulna joins together with the trochlea. The trochlea is divided in a medial and lateral portion and is [...]

Acromion Process

By Dr. Joseph H Volker | 2018-10-08T11:39:18+00:00 August 8th, 2018|Anatomy, Areas, Upper Limb|0 Comments

The acromion process is an anterolateral protuberance of the spine that arcs over the glenohumeral joint and articulates with the clavicle via a small oval facet on its distal end. Acromion process protrudes forward form the lateral end of spine, nearly at right angle and overhangs the glenoid cavity. It has subcutaneous superior surface. One [...]

Lateral Epicondyle of Humerus

By Dr. Joseph H Volker | 2018-08-30T08:47:55+00:00 August 8th, 2018|Anatomy, Areas, Upper Limb|0 Comments

The rounded protuberance at the end of a bone which is most often part of a joint or an attachment with another bone is called condyle. A rounded protuberance on a bone that is located upon a condyle is an epicondyle. Its lower part consists of the lateral supracondylar rim and the lateral border of [...]

Conoid Tubercle

By Dr. Joseph H Volker | 2018-08-30T09:35:26+00:00 August 8th, 2018|Anatomy, Areas, Upper Limb|0 Comments

The conoid tubercle is a bony protrusion at the inferior surface of the lateral third of the clavicle. Location The conoid tubercle is located near the posterior border on the junction of the lateral one-fourth along with medial three-fourth of the clavicle on the inferior surface. The trapezoid ridge spreads forwards as well as laterally [...]

Medial Epicondyle of Humerus

By Dr. Joseph H Volker | 2018-08-30T08:51:32+00:00 August 8th, 2018|Anatomy, Areas, Upper Limb|0 Comments

The rounded protuberance at the end of a bone which is most often part of a joint or an attachment with another bone is called condyle. A rounded protuberance on a bone that is located upon a condyle is an epicondyle. Medial Epicondyle of Humerus The medial epicondyle creates a prominent, blunt protuberance [...]

Glenoid Cavity

By Dr. Joseph H Volker | 2018-08-30T11:19:37+00:00 August 8th, 2018|Anatomy, Areas, Upper Limb|0 Comments

The scapula is a flat triangular bone and consists of three processes: the glenoid process, the acromial process, along with the coracoid process. The lateral angle of the scapula is represented by a shallow, somewhat comma-shaped glenoid cavity, which interconnects along with the head of the humerus in order to create the glenohumeral joint.
