Thumb sprains are common injuries where a ligament stretches or tears within your thumb joint. In severe thumb sprains, your ligament can be partially or completely torn, which often needs surgery. Treatment for thumb sprains often involves rest, using a splint and physical therapy.
A sprained thumb occurs when the ligaments that support the thumb are stretched beyond their limits. This commonly happens when a strong force bends the thumb backward, away from the palm of the hand. The most common way for this to occur is by falling onto an outstretched hand.
The most common mechanism of injury for a UCL sprain is when the thumb is in a position of full extension and then is forcefully abducted (pulled away from the body) or hyperextended. If the force exceeds the tensile strength of the ligament, a tear will occur.
Evaluation. Neurovascular and active flexion/extension testing will reveal clues to tendon and ligament injuries as well as subtle rotational abnormalities. The neurovascular evaluation should...
Common causes of finger sprains include: An injury that causes your finger either to bend too far or bend in the wrong direction. If your finger bends backwards, it’s called “hyperextension.”
A thumb may become sprained when the joint is stressed or overextended. We look at symptoms, treatment, and how to feel more comfortable during recovery. Medical News Today
Ligamentous injuries of the thumb IP joint range from mild sprains to complete ruptures, and the mechanism responsible is usually a hyperextension force to the joint, which may occur in some ball-handling sports or from a fall on an outstretched hand (FOOSH).
A thumb sprain can be caused when you hit your thumb forcefully against a hard surface or bend your thumb too far in one direction. Trying to soften a fall with your outstretched hand and...
Hyperextension: Aside from wear and tear, one of the most common causes of carpometacarpal joint injuries is a forced hyperextension of the first carpometacarpal joint (the base of the thumb). Carpometacarpal Joint Injury Symptoms. The symptoms associated with carpometacarpal joint injuries are similar to those of arthritis, including:
A hyperextension injury of the finger is a condition where any of the finger joint moves beyond its normal range of motion i.e. it hyperextends. The cause of this condition can include: playing racket sports and a heavy fall on an outstretched arm.
