Tremor Induced by Focal Peripheral Nerve Entrapment: A Case Series

Area of Science:

• Neurology
• Neurosurgery

Background:

• Tremors are often idiopathic or associated with central nervous system disorders.
• The link between peripheral nerve entrapment and tremors is not well-established.

Observation:

• Two patients presented with intentional tremors and symptoms of peripheral nerve compression in their hands.
• Case 1: Ulnar nerve double-crush compression at the cubital tunnel and Guyon canal.
• Case 2: Lacertus syndrome.

Findings:

• Surgical decompression of the affected nerves was performed in both cases.
• Following surgery, both patients experienced complete resolution of tremors.
• Neurological symptoms significantly improved in both patients at the 1-month follow-up.

Implications:

• Peripheral nerve entrapment should be considered in the differential diagnosis of tremors, especially when accompanied by neuropathy symptoms.
• Surgical nerve release can be an effective curative treatment for tremors caused by peripheral nerve compression.
