Investigating the relationship between ultrasound findings and the results of repair of Madin nerve tears in Imam Khomeini Hospital, Urmia

Abstract:
Introduction:
Median Nerve-traumatic injury is seen in 2.8% of trauma patients. Electrodiagnostic tests cannot provide the needed information about extent of healing, neuroma or scar formation following repair to help prognosis or decision -making on time for intervention. Sonography ,as a cheap, easily accessible tool might be helpful.


Materials & Methods: The median nerve traumatic injuries during one year in a teaching hospital were entered into a retrospective study. The cases with diabetes mellitus and systemic illness, congenital neuromuscular conditions, cervical discopathy were excluded. The cases underwent clinical , electro-diagnostic and ultrasonographic assessments three months post surgical repair.

Results:
within a one-year period ,21 patients -12 male and 9 female , with 20-55 years age range ,were evaluated 3 months post median nerve laceration repair.
The volume of neuroma formed at the site of repair was clearly less in cases with complete recovery than in patients with partial recovery. Also, the volume of neuroma formed at the site of repair was clearly lower
in cases with electromyographic results of nerve regeneration than in patients with severe
axonal injury, but with no statistical significance . All patients with injury at the carpal tunnel level had complete recovery after surgery, but without statistically significant relationship .
Conclusion: Ultrasound can be used as a low-cost and non-invasive method in the study of post -repair evaluation of peripheral nerve damage.
