Flexor tenosynovitis can develop
as early as 6 hours after the initial wound. Signs and symptoms include
fusiform swelling of the digit, and the digit or hand is held semi-flexed
and rigid. Passive flexion and extension are painful. Tenderness tends
to be greatest over the proximal portion of the tendon sheath.
Except in very early cases,
treatment is prompt surgical drainage, as involvement of a joint (other
than the thumb) may necessitate amputation.
