Ulnar nerve double crush by entrapment of a peri-cubital tunnel ganglion cyst and cubital tunnel: a case report.

BACKGROUND

Double crush syndrome (DCS) is a relatively rare nerve compression syndrome among peripheral nerve compression diseases. However, ulnar nerve double entrapment caused by peri-cubital tunnel ganglion cysts has been rarely reported.

CASE PRESENTATION: Here, we present a case of a 54-year-old woman who experienced occasional pain, numbness and paralysis in her right half hand for 1 year. A B-ultrasound of the right elbow initially revealed cubital tunnel syndrome only. Further Magnetic Resonance Imaging (MRI) showed a ganglion cyst near the cubital tunnel. After evaluation, we performed open surgery to excise the cyst and incise the cubital tunnel, completely decompressing the ulnar nerve entrapment. Ulnar nerve anterior transposition was also performed simultaneously.

CONCLUSIONS

The patient was followed up for 1 month, and she experienced a complete recovery with no functional limitations.

CLINICAL TRIAL NUMBER: Not applicable.
