Prechannel entrapment of the ulnary nerve by an intermuscular arcade: The importance of ultrasonographic neurography in the demonstrating of compression site
Özet
Aim: Ultrasonographic neurography is a described method in the cases with peripheral nerve injury and entrapment. The usual entrapment of the peripheral nerves had been described previously. Material and Method: In this report it was presented the unusual entrapment of the ulnar nerve and the neurographic findings in an illustrative case. The case was admitted to our neurosurgery department with the symptoms of ulnar nerve entrapment. Results: Electrophisiologic examination revealed that ulnary nerve entrapment before entering ulnary nerve canal. We examined the patient by using ultrasound assisted neurographic examination before operation. Ultrasonographic neurography demonstrated ulnary nerve compression 5 cm proximal portion from its entrance into the ulnary nerve canal. The patient was operated. Operative findings were similar with those of ultrasonographic neurography. Discussion: In this report we present clinical and operative findings of this case including the role of ultrasonographic neurography in the demonstrating these type of pathologies in the clinical practice.
