The cubital tunnel is bordered medially by the medial epicondyle of the humerus, laterally by the olecranon process of the ulna and the tendinous arch joining the humeral and ulnar heads of the flexor carpi ulnaris. [1]
Olecranon bursitis is a condition characterized by swelling, redness, and pain at the tip of the elbow. [ 1 ] [ 2 ] If the underlying cause is due to an infection , fever may be present. [ 2 ] The condition is relatively common and is one of the most frequent types of bursitis .
A bursectomy is the removal of a bursa, which is a small sac filled with synovial fluid that cushions adjacent bone structures and reduces friction in joint movement. This procedure is usually carried out to relieve chronic inflammation ( bursitis ) or infection , when conservative management has failed to improve patient outcomes.
Since bursitis is caused by increased friction from the adjacent structures, a compression bandage is not suggested because compression would create more friction around the joint. Chronic bursitis can be amenable to bursectomy and aspiration. [1] Bursae that are infected require further investigation and antibiotic therapy. Steroid therapy may ...
The prepatellar bursa and the olecranon bursa are the two bursae that are most likely to become infected, or septic. [10] Septic bursitis typically occurs when the trauma to the knee causes an abrasion, though it is also possible for the infection to be caused by bacteria traveling through the blood from a pre-existing infection site.

The olecranon is situated at the proximal end of the ulna, one of the two bones in the forearm. [1] When the hand faces forward the olecranon faces towards the back (posteriorly). It is bent forward at the summit so as to present a prominent lip which is received into the olecranon fossa of the humerus during extension of the forearm. [2] [3]
Anderson and colleagues from St Thomas' Hospital, London, were the first to mention a case with possible clinical findings of LEMS in 1953, [11] but Edward H. Lambert, Lee Eaton, and E.D. Rooke at the Mayo Clinic were the first physicians to substantially describe the clinical and electrophysiological findings of the disease in 1956.
An articular branch that passes to the elbow joint while the ulnar nerve is passing between the olecranon and medial epicondyle of the humerus; In the forearm, via the muscular branches of ulnar nerve: Flexor carpi ulnaris [5] Flexor digitorum profundus (medial half) [5] In the hand, via the deep branch of ulnar nerve: [5] Hypothenar muscles
