Marked swelling about the left elbow was noted particularly at the olecranon process and common wrist extensor musculature.
The monitor measuring flexion/ extension was positioned at the approximate center of wrist thickness on the ulnar side slightly proximal to the styloid process, aligned with the ulnar aspect of the fifth metacarpal distally and the tip of the olecranon process proximally.
* Triceps: Vertical fold, on the posterior midline of the upper arm, halfway between acromion and olecranon process
Ueh: antero-posterior width of proximal end, taken from the most extreme point of olecranon process to the most extreme point of coronoid process.
Olecranon bursitis or capped elbow is inflammation of an acquired, subcutaneous bursa over the olecranon process of ulna i.e.
The biceps skinfold thickness was measured as the thickness of a vertical fold raised on the anterior aspect of the arm, the triceps skinflold thickness was measured over the triceps muscle at a point midway between the lateral projection of the acromion process of scapula and the inferior margin of the olecranon process of ulna .The subscapular skinfold was picked up on a diagonal, inclined inferolaterally approximately 45c to the horizontal plane in the natural cleavage line of the skin.
Mid-arm circumference (MAC) (cm) was measured using a plastic tape at the mid-point between the acromion and olecranon process to the nearest 0.1 cm.
Importance of Accurate Reduction: Extension of the elbow joint is limited by the olecranon process locking in the olecranon fossa of humerus.
Forearm circumference: Forearm circumference was measured at midpoint between olecranon process of ulna and styloid process of radius bones by flexible measuring tape.
Trauma, Excessive movement of skin and tear the subcutaneous connective tissue over the olecranon process causes subcutaneous accumulation of transudative fluid that eventually, becomes encapsulated by fibrous tissue lined with a synovial like membrane (Shappel and Little, 1992).
The smaller humeral head arises from the medial epicondyle of the humerus and larger ulnar head has an extensive origin from the medial margin of the olecranon process, proximal two thirds of posterior border of ulna, an aponeurosis which is common for FCU, extensor carpi ulnaris muscle and flexor digitorum profundus muscle and intermuscular septum between it and flexor digitorum superficialis muscle.
