Extension type of supracondylar humerus fractures typically result from a fall on to an outstretched hand, usually leading to a forced hyperextension of the elbow. The olecranon acts as a fulcrum which focuses the stress on distal humerus (supracondylar area), predisposing the distal humerus to fracture.
Isometric exercise avoids hyperextension and contributes to strength. Unwanted symptoms are frequently reduced by some forms of yoga; Low-impact sports Use of low impact elliptical trainer machines can replace high-impact running. Pain-free swimming may require a kickboard or extra care to avoid hyperextending elbow and other joints.
The acute rupture occurs in collisions when the elbow is in flexion such as that in a wrestling match or a tackle in football. The ulnar collateral ligament distributes over fifty percent of the medial support of the elbow. [16] [17] This can result in an UCL injury or a dislocated elbow causing severe damage to the elbow and the radioulnar joints.
A hand imitating an ulnar claw. The metacarpophalangeal joints of the 4th and 5th fingers are extended and the Interphalangeal joints of the same fingers are flexed.. An ulnar claw, also known as claw hand or Spinster’s Claw, is a deformity or an abnormal attitude of the hand that develops due to ulnar nerve damage causing paralysis of the lumbricals.
Elbow pain is a common complaint in both the emergency department and in primary care offices. The CDC estimated that 1.15 million people visited an emergency room for elbow or forearm-related injuries in 2020. [1] There are many possible causes of elbow discomfort but the most common are trauma, infection, and inflammation.
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.
