A broken finger or finger fracture is a common type of bone fracture, affecting a finger. [1] Symptoms may include pain, swelling, tenderness, bruising, deformity and reduced ability to move the finger. [2] Although most finger fractures are easy to treat, failing to deal with a fracture appropriately may result in long-term pain and disability ...
Symptoms of Bennett fracture are instability of the CMC joint of the thumb, accompanied by pain and weakness of the pinch grasp. Characteristic signs include pain, swelling, and ecchymosis around the base of the thumb and thenar eminence, and especially over the CMC joint of the thumb.
Fractures in the proximal third have a high incidence of AVN (~30%) Waist fractures in the middle third is the most frequent fracture site and has moderate risk of AVN. Fractures in the distal third are rarely complicated by AVN. Non union can also occur from undiagnosed or undertreated scaphoid fractures. Arterial flow to the scaphoid enters ...
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.
X-rays may be employed to achieve a more accurate diagnosis of a jammed finger, enabling the identification of varying types of dislocation or fractures. In order to account for all possibilities, it is recommended that a variety of views (lateral, oblique, and anteroposterior) are observed. [2] Joints of the finger
Of the three types of occult fractures mentioned above, the latter two, fatigue fracture secondary to repetitive and unusual stress being applied to bone with normal elastic resistance, and insufficiency fracture resulting from normal or minimal stress on a bone with decreased elastic resistance are also described as "stress fractures".

Gamekeeper's thumb and skier's thumb are two similar conditions, both of which involve insufficiency of the ulnar collateral ligament (UCL) of the thumb. The chief difference between these two conditions is that skier's thumb is generally considered to be an acute condition acquired after a fall or similar abduction injury to the metacarpophalangeal (MCP) joint of the thumb, whereas gamekeeper ...
Anterior interosseous syndrome is a medical condition in which damage to the anterior interosseous nerve (AIN), a distal motor and sensory branch of the median nerve, classically with severe weakness of the pincer movement of the thumb and index finger, and can cause transient pain in the wrist (the terminal, sensory branch of the AIN innervates the bones of the carpal tunnel).
