The head of the radius is wider than the bone's neck, and, because the annular ligament embraces both, the radial head is "trapped" inside the ligament which thus acts to prevent distal displacement of the radius. [4] It helps to stabilise the proximal radial head, [6] and the radioulnar joint. [7]
During pronation the radius is rotated so that the head's major axis reaches the radial notch on the ulna. This causes a small but significant lateral displacement of the radius' main axis — equal to half the difference between the two axes of the head (2 mm (0.079 in)) — just enough space to accommodate the radial tuberosity as it being ...
Radial referring to the radius bone, seen laterally in the standard anatomical position. Ulnar referring to the ulna bone, medially positioned when in the standard anatomical position. Additional terminology is used to describe the movement and actions of the hands and feet, and other structures such as the eyes.
According to the Oxford English Dictionary, the etymology is uncertain, but probably derives from the slang term "bean", meaning "head".In New Zealand and Australia, the term "beanie" is normally applied to a knit cap known as a toque in Canada and parts of the US, but also may apply to the kind of skull cap historically worn by surf lifesavers [1] and still worn during surf sports.

Injury to Erb's point is commonly sustained at birth or from a fall onto the shoulder.The nerve roots normally involved are C5 and partly C6. Symptoms include paralysis of the biceps, brachialis, and coracobrachialis (through the musculocutaneous nerve); the brachioradialis (through the radial nerve); and the deltoid (through the axillary nerve).
A subluxation of the humeroradial joint is called a "nursemaid's elbow", also known as radial head subluxation. [1]It is generally caused by a sudden pull on the extended pronated forearm, such as by an adult tugging on an uncooperative child or by swinging the child by the arms during play.
A side cap is a military cap that can be folded flat when not being worn. It is also known as a garrison cap or flight cap in the United States, wedge cap in Canada, or field service cap in the United Kingdom. [1] In form the side cap is comparable to the glengarry, a folding version of the Scottish military bonnet. It has been associated with ...
