While it can look unsightly - the finger turns shades of purple and red and can swell, the condition resolves by itself. Paroxysmal hand hematoma is a skin condition characterized by spontaneous focal hemorrhage into the palm or the volar surface of a finger, which results in transitory localized pain, followed by rapid swelling and localized ...
The slow process of reabsorption of hematomas can allow the broken down blood cells and hemoglobin pigment to move in the connective tissue. For example, a patient who injures the base of their thumb might cause a hematoma, which will slowly move all through their finger within a week. Gravity is the main determinant of this process.
The radialis indicis artery (radial artery of index finger) is a branch of the radial artery that provides blood to the index finger.. It arises close to the princeps pollicis artery, and descends between the first dorsal interosseous muscle and the transverse head of the adductor pollicis, and runs along the lateral side of the index finger to its extremity, where it anastomoses with the ...
External bleeding is generally described in terms of the origin of the blood flow by vessel type. The basic categories of external bleeding are: Arterial bleeding: As the name suggests, blood flow originating in an artery. With this type of bleeding, the blood is typically bright red to yellowish in colour, due to the high degree of oxygenation.
Bleeding, hemorrhage, haemorrhage or blood loss is blood escaping from the circulatory system from damaged blood vessels. [1] Bleeding can occur internally , or externally either through a natural opening such as the mouth , nose , ear , urethra , vagina or anus , or through a puncture in the skin .
Fractures of the fingers occur when the finger or hands hit a solid object. Fractures are most common at the base of the little finger (boxer's fracture). Nerve injuries occur as a result of trauma, compression or over-stretching. Nerves send impulses to the brain about sensation and also play an important role in finger movement.
The blood pools under the nail, giving a reddish, brownish, blueish, or grey/blackish discoloration. The blood puts pressure to the nailbed causing pain which can be throbbing in quality and disappears when the pressure on the nail bed is relieved. [2] Subungual hematomas typically heal without incident, though infection may occur.
The ulnar artery is the main blood vessel, with oxygenated blood, of the medial aspects of the forearm. It arises from the brachial artery and terminates in the superficial palmar arch, which joins with the superficial branch of the radial artery. It is palpable on the anterior and medial aspect of the wrist.
