Radial head fractures are a common type of elbow fracture that typically occurs after a fall on an outstretched arm. [1] They account for approximately one third of all elbow fractures and are frequently associated with other injuries of the elbow. [2] [3] Radial head fractures are diagnosed by a clinical assessment and medical imaging.
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]
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 ...
An injury resulting in an outward (valgus) stress on the elbow, such as falling on an outstretched hand causes an avulsion fracture of the medial epicondyle. [citation needed] The medial epicondyle is often the final growth plate (ossification center) to ossify in the elbow. Growth plates are particularly vulnerable to injury compared to bone.

Pipkin: posterior dislocation of hip with avulsion fracture of fragment of femoral head by the ligamentum teres: impact to the knee with the hip flexed (dashboard injury)
The posterior fat pad is normally pressed in the olecranon fossa by the triceps tendon, and hence invisible on lateral radiograph of the elbow. [3] When there is a fracture of the distal humerus, or other pathology involving the elbow joint, inflammation develops around the synovial membrane forcing the fat pad out of its normal physiologic resting place.
A partial dislocation is referred to as a subluxation. Dislocations are often caused by sudden trauma on the joint like an impact or fall. A joint dislocation can cause damage to the surrounding ligaments, tendons, muscles, and nerves. [2] Dislocations can occur in any major joint (shoulder, knees, etc.) or minor joint (toes, fingers, etc.).
The success of the Krukenberg procedure depends directly on the strength of the pronator teres, the sensibility of the skin surrounding both ulna and radius, elbow mobility, and mobility of the ulna and radius at the proximal radioulnar joint. Individual patient expectations and motivations, although more difficult to assess, probably play a ...
