For an intact bone, the head faces medially, the capitulum is lateral, and the olecranon fossa is posterior. This technique can be successfully employed even in comminuted and unstable fracture patterns without the fear of loss of reduction and risk of iatrogenic ulnar nerve injury. Operative fixation of the olecranon includes tension band wiring, intramedullary fixation, or fixation with plates and screws.

Louise Scheuer, in Juvenile Osteology, 2009. Posteriorly, the capsule is tight in flexion; anteriorly, the capsule is tight in extension. The LCL provides significant stability to the elbow because of its resistance to varus and posterolateral forces. If the articular end is missing, the coronoid fossa is larger and more medial than the radial fossa. This forms the attachment site for the humerus over the ulnar surface. In elbow extension, the tip of the ulnar olecranon process lodges into this fossa. articulates with fossa of humerus. Make up the wrist, eight bones Scaphoid, Lunate, Triquetrum, Pisiform, Trapezium, Trapezoid, Capitate, Hamate.

[TA] a hollow on the anterior surface of the distal end of the humerus, just above the trochlea, in which the coronoid process of the ulna rests when the elbow is flexed. Operative: Access to OCD lesions on the medial ridge of the talus can be achieved through a medial operative portal distal to the medial malleolus and immediately caudal to the collateral ligament. The canine alveolus in the mandible is deeper than the incisor alveolus. An olecranon foramen, also known as septal aperture or supratrochlear foramen, is a common normal anatomical variant of the distal humerus. Olecranon fossa - Fossa olecrani. How many such bones are present in the body? OLECRANON FOSSA SYNDROME The olecranon process is a large, thick, and curved eminence of the proximal ulna that forms the point of the elbow.
