Describe the epidemiology of flexor tendon injuries of fingers? (incidence rising or decreasing, sex, age)
44
Describe the zones of the hand to describe flexor injuries?
45
Describe the management of flexor of the hand injuries?
* Surgically and early * Beware old injuries * Partial tears (\<60%) do not require repair * Rehabilitation * Early movement (stress) increases healing and strength
