[Nerve transfer in patients with tetraplegia: improvement in hand function].

Reconstruction of arm and hand function in patients with a cervical spinal cord injury can improve their quality of life. Elbow extension, wrist extension, grip function and opening of the hand can be reconstructed. Traditionally, this has been done through tendon transpositions. Nerve transfer is a new technique. A functioning motor nerve branch is moved and connected to a muscle or muscle group damaged by the spinal cord injury. This technique has several advantages. Multiple functions can be restored by one nerve transfer, no long-term hand-rehabilitation is required and there is no risk of adhesions of the transposition. The most important disadvantage is the recovery time, as a results of the slow ingrowth of the nerve transfer, which takes at least 12 to 18 months. For each spinal cord injury patient, an individual action plan must be made, because not every patient has the same options and these are sometimes very limited.
