De Quervain’s tendinitis, also known as Quervain’s tenosynovitis, is caused by
irritation and inflammation of the tendons located at the base of the thumb, usually
as a result of repetitive movements. Some traumatic injuries resulting from
fractures in which an increase of tendon tension is evident can predispose the
occurrence of tendinitis in the first dorsal compartment.
Sudden or gradual pain originating in the first dorsal compartment of the wrist
and thumb, radiating to the forearm.
Pain increases with mechanical effort, gripping or squeezing objects, together
with pronosupination movements of the wrist.
Possible loss of sensitivity in the thumb and index finger.
Passive wrist and thumb immobilising splints, in which the wrist, trapeziometacarpal
and proximal metacarpophalangeal joints are immobilised at rest and in a
functional position, enabling reduction of irritation and inflammation, are a perfect
complement to rehabilitation techniques.
