Continuous ulnar nerve block at the forearm for early active mobilisation following flexor tendon reconstruction

Continuous ulnar nerve block at the forearm for early active mobilisation following flexor tendon... A 63‐year‐old woman had sustained a subcutaneous rupture of the flexor digitorum profundus tendon of the little finger due to osteoarthritis of the pisotriquetral joint. She underwent excision of the pisiform bone and reconstruction of the flexor digitorum profundus tendon of the little finger using an autogenous palmaris longus tendon graft. After surgery, a continuous ulnar nerve block was performed at the forearm under ultrasound and nerve stimulator guidance. During rehabilitation, she could not actively extend her little finger independently due to the block; however, she could actively extend it when the dorsum of the metacarpophalangeal joint was pressed by the occupational therapist, resulting in successful early active mobilisation. A continuous ulnar nerve block at the forearm may help to facilitate early active mobilisation after reconstructive surgery for little finger flexor tendon rupture. However, it may restrict the active extension of the little finger because the block does not spare the innervation of the intrinsic muscles responsible for little finger extension. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Anaesthesia Reports Wiley

Abstract

A 63‐year‐old woman had sustained a subcutaneous rupture of the flexor digitorum profundus tendon of the little finger due to osteoarthritis of the pisotriquetral joint. She underwent excision of the pisiform bone and reconstruction of the flexor digitorum profundus tendon of the little finger using an autogenous palmaris longus tendon graft. After surgery, a continuous ulnar nerve block was performed at the forearm under ultrasound and nerve stimulator guidance. During rehabilitation, she could not actively extend her little finger independently due to the block; however, she could actively extend it when the dorsum of the metacarpophalangeal joint was pressed by the occupational therapist, resulting in successful early active mobilisation. A continuous ulnar nerve block at the forearm may help to facilitate early active mobilisation after reconstructive surgery for little finger flexor tendon rupture. However, it may restrict the active extension of the little finger because the block does not spare the innervation of the intrinsic muscles responsible for little finger extension.
