stenosing tenovaginitis
This is a type of tenosynovitis of the tendons of the muscles of the
thumb as they pass into the wrist. The pain is over the styloid process
of the radius and there is a palpable nodule in the course of the
abductor pollicus longus and extensor poilicus brevis tendons. This is
a similar condition to trigger finger. The cause is unknown but is
often associated with repetitive activities involving much use of the
thumb and forefinger and wrists such as wringing clothes, working at
machines or on assembly lines.

- dupuytren's
contracture
This is a condition characterised by a flexion contracture of one or
more of the fingers due to thickening and shortening of the palmar
aponeurosis (thin fibrous sheet of tissue on the palm of the hand). The
flexion is much more common in men than in women and often both hands
are affected. The other sign is a small, thickened module in the mid
palm opposite the base of the ring finger. The area thickened gradually
spreads from this point giving rise eventually to firm cord like bands
that extend into the ring or little finger preventing full extension of
the metacarpal-phalangeal, and the proximal inter-phalangeal joints.
The flexion deformity becomes progressively worse over the course of
months or years and surgery may be necessary.
