A large process of the ulna projecting behind the elbow joint and forming the bony prominence of the elbow. A fossa do olecrano é encontrada no úmero, mais especificamente na parte distal do úmero, essa fossa é o local onde uma estrutura chamada olecrano se insere parcialmente. olecranon fossa, coronoid fossa. When trying to understand the relative positioning of boney features, the condyles found at the distal end of the humerus can help orientate which side of the humerus it may belong to. olecranon process - process of the ulna that forms the outer bump of the elbow and fits into the fossa of the humerus when the arm is extended. Estruturas anatômicas. Use a saw to cut distal to the outermost circular groove made by the reamer to remove the remains of the trochlea along the previously marked lines (Figure 8). The olecranon can thus be fractured (avulsed) by a traction force from triceps contracture. Deep dissection. A bone contains a. olecranon fossa, b. deltoid tuberosity, c. head, and d. medial epicondyle. 12. The olecranon fossa is a deep triangular depression on the posterior side of the humerus, superior to the trochlea, in which the summit of the olecranon is received during extension of the forearm. They have been reported mainly in the olecranon fossa [1-3] or in the coronoid fossa [4] Clinical and radiographic diagnosis is often difficult [3,5,6]. The olecranon has a beak-like structure and is bent forwards into the olecranon fossa of the humerus during extension of the elbow. This forms the attachm… On the posterior surface of the lower end of the humerus, a depression proximal to the trochlea and between the medial and lateral epicondyles; it is analogous to the coronoid fossa on the opposite side of the humerus. The subcutaneous location of the olecranon makes it vulnerable to trauma. 2. INTRODUCTION. Olecranon fractures may occur as a result of direct trauma, indirect trauma, or a combination of both. Extension is limited by the olecranon reaching the olecranon fossa, tension in the anterior ligament, and resistance in flexor muscles. This is a large, curved bony prominence which is accepted into the olecranon fossa, located on the humerus, during elbow extension. Preoperative radiographs revealed osteophytes on coronoid process, olecranon tip, coronoid fossa, radial fossa and olecranon fossa. It passes in the groove between the medial epicondyle and the olecranon fossa (Fig. ulna, proximal end. The distal fragment is usually small and osteoporotic and stable fixation is not easy to achieve. 6-1). How many such bones are present in the body? Elbow joint. The olecranon fossa is contiguous with the radial fossa, a similar excavation on the cranial aspect of the distal metaphysis of the humerus, via the supratrochlear foramen.
