de Quervain’s Tenosynovitis What is it? de Quervain’s tenosynovitis refers to inflammation of the soft tissues surrounding the tendons that move the thumb – it is an overuse injury. de Quervain’s tenosynovitis affects two thumb tendons. These tendons are responsible for extending the thumb backwards and for moving the thumb away from the palm of the hand. These tendons connect their respective muscles in the forearm to the thumb. On their way to the thumb, the tendons slide through a thick fibrous sheath that forms a tunnel. Normally the tendons glide easily back and forth within this tunnel but in de Quervain’s tenosynovitis the tunnel is tight and irritates the tendons. See figure 1. Figure 1 What are the symptoms?
