Elbow fractures are any broken bone in or near the elbow joint and include olecranon fractures, supracondylar humerus fractures and radial head fractures. [1] The elbow joint is formed by three different bones: the ulna, radius, and humerus that permit the joint to move like a hinge and allow a person to straighten and bend their arm and these bones are connected by tendons, ligaments, and ...
The olecranon (/ oʊ ˈ l ɛ k r ə n ɒ n /, from Greek olene 'elbow' and kranon 'head'), is a large, thick, curved bony process on the proximal, posterior end of the ulna.It forms the protruding part of the elbow and is opposite to the cubital fossa or elbow pit (trochlear notch).
Olecranon fracture is a fracture of the bony portion of the elbow. The injury is fairly common and often occurs following a fall or direct trauma to the elbow. The olecranon is the proximal extremity of the ulna which is articulated with the humerus bone and constitutes a part of the elbow articulation. Its location makes it vulnerable to ...
Because dislocations make the knee unstable, 15% of patellas will re-dislocate. [31] Patellar dislocations often occur when the knee is in full extension and sustains a trauma from the lateral to medial side. [32] Elbow: Posterior dislocation, 90% of all elbow dislocations [33] Wrist: Lunate and Perilunate dislocation most common [34]
Elbow dislocation and radial head or neck fractures are common when one falls on an outstretched hand. [18] Elbow Dislocations are divided into two categories; Simple and complex. Simple dislocations are defined as soft tissue injury whereas complex involves a fracture.
Elbow dislocations constitute 10% to 25% of all injuries to the elbow. The elbow is one of the most commonly dislocated joints in the body, with an average annual incidence of acute dislocation of 6 per 100,000 persons. [30] Among injuries to the upper extremity, dislocation of the elbow is second only to a dislocated shoulder. A full ...

Osteosynthesis (open reduction and internal fixation) of the ulnar shaft is considered the standard of care in adults. It promotes stability of the radial head dislocation and allows very early mobilisation to prevent stiffness. [5] The elbow joint is particularly susceptible to loss of motion. [citation needed]
