Hypermobility, also known as double-jointedness, describes joints that stretch farther than normal. [2] For example, some hypermobile people can bend their thumbs backwards to their wrists and bend their knee joints backwards, put their leg behind the head or perform other contortionist "tricks".
Most small joint manipulation is done on the hands or feet to hyperextend joints as part of a pain compliance strategy. The basic techniques of small-joint manipulation involve grabbing and bending back one or more fingers/toes and by applying pressure to the wrist/ankle joints that disrupt the interconnectivity of the system of smaller joints within.
It is a variation of a jammed finger, where the extensor tendons on the back of the finger are damaged. [18] Mallet finger occurs in similar situations as a jammed finger. The tendon that extends the tip of the finger is torn due to trauma causing it to flex beyond normal range. [17]
Finger sprains occur when the ligaments which are attached to the bone are overstretched and this results in pain, swelling, and difficulty for moving the finger. Common examples of a sprain are jammed or twisted fingers. These injuries are common among ball players but can also occur in laborers and handy men.
Finger displacement towards the back of the hand is often irreducible due to associated injuries, while finger displacement towards the palm of the hand is more readily reducible. [23] Overall, recovering from a joint dislocation can range from a few weeks to months, depending on the severity of the injury.
Ligamentous laxity or ligament laxity can appear in a variety of ways and levels of severity. In most people, ligaments (which are the tissues that connect bones to each other) are naturally tight in such a way that the joints are restricted to 'normal' ranges of motion. This creates normal joint stability.
At home, you strive to be super careful with your clubbed thumbs while handling plates, wine glasses and other fragile items, but the fact is, your dish collection leaves much to be desired. 4 ...
Symptoms of Bennett fracture are instability of the CMC joint of the thumb, accompanied by pain and weakness of the pinch grasp.
