Tremor Induced by Focal Peripheral Nerve Entrapment: A Case Series.

Little is known about tremors caused by peripheral nerve entrapment. We report two cases of tremors caused by peripheral nerve compressions. Two patients presented with intentional tremors combined with peripheral nerve compression symptoms on their affected hand. Based on the clinical findings and evaluations, the first patient was diagnosed with double-crush compression of the ulnar nerve at the cubital tunnel and Guyon canal, and the second patient was diagnosed with lacertus syndrome. The first patient underwent surgical release of the cubital tunnel and Guyon canal in two stages. The second patient underwent release of the lacertus fibrosus. At the 1-month follow-up after surgery, the tremors had completely resolved, and neurological symptoms improved. Peripheral nerve entrapment should be considered a potential cause of tremors in patients with tremors combined with symptoms of peripheral neuropathy. Surgical release can be curative.
