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.
Radioulnar synostosis is a rare condition where there is an abnormal connection between the radius and ulna bones of the forearm. [1] This can be present at birth ( congenital ), when it is a result of a failure of the bones to form separately, or following an injury (post-traumatic).
The forearm is the region of the upper limb between the elbow and the wrist. [1] The term forearm is used in anatomy to distinguish it from the arm , a word which is used to describe the entire appendage of the upper limb, but which in anatomy, technically, means only the region of the upper arm, whereas the lower "arm" is called the forearm.
Direct blow on back of upper forearm would be a very uncommon cause. In this context, isolated ulnar shaft fractures are most commonly seen in defence against blunt trauma (e.g. nightstick injury). Such an isolated ulnar shaft fracture is not a Monteggia fracture. [citation needed] It is called a 'nightstick fracture'.
The Colles fracture is named after Abraham Colles (1773–1843), an Irish surgeon, from Kilkenny who first described it in 1814 by simply looking at the classic deformity before the advent of X-rays. [14] Ernest Amory Codman was the first to study it using X-rays.
Radial deviation of the wrist is caused by lack of support to the carpus, radial deviation may be reinforced if forearm muscles are functioning poorly or have abnormal insertions. [3] Although radial longitudinal deficiency is often bilateral, the extent of involvement is most often asymmetric. [1]
Hypertrophic cardiomyopathy develops when the walls of your left ventricle become thicker than normal. It’s the most common cardiomyopathy caused by inherited genes. Restrictive cardiomyopathy.
Cubitus valgus is a medical deformity in which the forearm is angled away from the body to a greater degree than normal when fully extended. A small degree of cubitus valgus (known as the carrying angle) is acceptable and occurs in the general population.
