TREATMENT OF PAINFUL NEUROMAS OF THE HAND AND WRIST BY RELOCATION INTO THE PRONATOR QUADRATUS MUSCLE

Thirteen painful end-neuromas of nerves of the palm and the dorsum of the hand were treated by resection of the neuroma and relocation of th e nerve ends into the pronator quadratus muscle proximal to the wrist in ten patients. The effectiveness of this treatment was assessed by m easurement of changes in level of spontaneous pain, pain on pressure, pain on movement and hyperaesthesia at the original site and at the si te to which the nerve was relocated, Subjective comments on changes of hand function and ability to return to work were also recorded. All t en patients reported total relief or marked improvement in each of the four modalities of pain assessed. In the five patients in whom the ne uromas were the only significant cause of hand dysfunction, there was sufficient improvement in hand function to allow the patients to retur n to work. In this series, the pronator quardratus muscle has proved a suitable site for relocation of sensory nerve ends after resection of painful neuromas in the proximal part of the hand and wrist.
