Purpose:
This study compares the clinical results of microsurgical nerve repairs in unilateral digital arterial-nerve-injuries with and without repair of the finger artery.
Patients And Methods:
Between January 2000 and May 2007 a total of 81 patients with unilateral digital vascular nerve bundle lesions, including concomitant soft-tissue tendon lesions, were operated on the emergency day. Forty of the 56 patients treated with a nerve repair alone took part in a follow-up after an average of 47 (7-87) months. Twenty of the 25 patients treated with a microsurgical arterial and nerve repair took part in a follow-up after an average of 12 (6-66) months; 3 patients were excluded due to a negative digital Allen-test. In addition to anamnestic data, peripheral nerve function was evaluated by the static and the moving two-point discrimination test, and by Semmes-Weinstein pressure aesthesiometer in the autonomous zone of the affected side of the injured finger. Stereognosis also was examined. The patency of the reconstructed digital artery was tested by a digital Allen-test.
Results:
No statistically significantly worse results were found in patients with a nerve repair alone compared to patients with additional repair of the finger artery.
Conclusion:
Repair of the finger artery therefore appears to offer no improvement of the clinical outcome following nerve repair in unilateral injury of a digital arterial-nerve bundle.
