Summary
Evaluating nerve reconstruction outcomes requires precise methods. Two-point discrimination, aided by the two-point-star, is the most reliable quantitative measure for assessing sensory nerve repair success.
Area of Science:
- Neurosurgery
- Microsurgery
- Reconstructive Surgery
Background:
- Nerve reconstruction often involves complementary use of suture and autogenous grafts.
- Objective parameters are needed to reliably evaluate the success of sensory nerve repair.
Purpose of the Study:
- To identify the most valid quantitative measurement for assessing sensory nerve reconstruction.
- To compare different clinical tests used in evaluating nerve repair outcomes.
Main Methods:
- Review of current practices in nerve reconstruction.
- Evaluation of various clinical tests including action potential, Moberg-test, two-point discrimination (with two-point-star), and Millesi-test.
Main Results:
- Action potential of sensory nerves is not an objective parameter for evaluating results.
- The Moberg-test can detect pinch deficits.
- Two-point discrimination is identified as the most valid quantitative measurement for sensory reconstruction.
- The two-point-star simplifies the two-point discrimination test.
- The Millesi-test demonstrates good correlation with two-point discrimination.
Conclusions:
- Two-point discrimination is the preferred quantitative method for evaluating sensory nerve reconstruction.
- Clinical tests like the Moberg-test and Millesi-test can supplement sensory testing but do not replace two-point discrimination.
