Risk factors for hand disability:
(1) loss or significant reduction in sensation
(2) recurrent trauma to the hand, with the digits most vulnerable
(3) chronic and recurrent infection, especially over the distal aspects of the fingers
(4) abnormal pressure on soft tissue when compensating for loss of function
(5) ischemia of the digits
(6) performing activities in an unsafe manner
Recurrent trauma involving an open wound is associated with a high risk of deformity,
Signs of potential problems on physical examination:
(1) open wounds, especially if infected
(2) calluses or scars indicating points of abnormal stress
(3) abnormal pinch (side pinch rather than pulp pinch)
(4) loss of spherical and cylindrical grasp (no or hook grasp)
(5) partial absorption of one or more fingers
