Table saw accident splitting the thumb in half! ⚠️

The thumb was able to be reconstructed and ended up healing well with partial loss of sensation. Sensation to the finger is supplied by four nerves, two (dorsal and volar digital nerves) running along each side of the finger. Damaging the nerve can cause numbness on the side of the finger supplied by the nerve. Digital nerve lacerations are common in hand trauma surgery and are even the most frequently injured of the peripheral nerves. Digital nerve injury can result from simple cuts or from severe hand trauma. In case a digital nerve is left unrepaired, the axonal growth will disperse and could lead to neuroma formation which then would interfere with rehabilitation, functional recovery, and sensory deficit especially in the thumb and the second digit which are involved in pinch and gnostic function. Sensibility is an essential factor, concerning a normal hand function. Primary repair by end-to-end neurorrhaphy is usually performed to try and restore the function.
