Bursae are small, fluid-filled sacs whose function is to reduce friction, distribute stress, and protect the underlying structures. They may be found between a bone and a tendon, between two tendons, or between a bone or tendon and the overlying skin. There are a number of permanent bursae around the hips, knees, feet, shoulders, and […] Introduction A distal biceps rupture occurs when the tendon attaching the biceps muscle to the elbow is torn from the bone. This injury occurs mainly in middle-aged men during heavy work or lifting. A distal biceps rupture is rare compared to ruptures where the top of the biceps connects at the shoulder. Distal biceps ruptures […] Introduction The usual cause of bleeding into a bursa is a direct impact such as a fall. It may also be caused indirectly by tendon rupture or by bleeding within a joint to which the bursa is connected. Blood within the bursa causes chemical irritation, and in severe cases, may clot and cause adhesion of […] Positioning. The subject stands with the arm hanging and the elbow bent to a right angle. The examiner stands in front of the subject. Both hands encircle the distal forearm in such a way that the heel of the contralateral hand is placed against the volar part of the ulna and the fingers of the […] Over the olecranon lies the olecranon bursa,which is only really palpable when it becomes inflamed and swollen.Keep the subject’s elbow flexed. Palpate for the upper border (apex) of the olecranon. Feel just lateral to this apex for the insertion of the tendon of the triceps muscle. Move the fingers upwards: a broad and flat tendon […] Ask the subject to contract the biceps. Place the thumb and fingers in the indentations on both sides of the bicipital tendon (the lateral and medial bicipital grooves) and now ask for an isometric nexion. Under the fingers – and behind the biceps tendon – the contraction of the brachialis muscle can be felt. During […] |
