ABSTRACT
Observation The hand should be observed in the resting position. This is termed the posi
tion of function. The wrist will be slighdy dorsiflexed, the MP joints will be in 45-75° o f flexion, the PIP joints in about 10° of flexion, and the DIP joints will be in 0-10° of flexion. Any alterations in the normal resting position should be noted. A single finger fixed in extension can be due to a flexor tendon laceration or rupture. A single finger in fixed flexion may be due to an extensor tendon injury. If the abnormal flexion is chronic, flexor tendon contracture must also be considered. This can be seen in Dupuytrens disease.
