Smart device neuropathy

Area of Science:

• Neurology
• Medical Devices

Background:

• Meralgia paresthetica is a condition caused by compression of the lateral femoral cutaneous nerve (LFCN).
• Common causes include obesity, pregnancy, and tight clothing.
• The LFCN supplies sensation to the anterolateral thigh.

Observation:

• Two cases of meralgia paresthetica were identified.
• The compression of the LFCN in both cases was attributed to the use of portable electronic or "smart" devices.
• These devices were positioned in a manner that exerted pressure on the nerve.

Findings:

• Portable electronic devices can act as an external factor causing LFCN compression.
• This represents a novel etiology for meralgia paresthetica.
• Symptoms of meralgia paresthetica may arise from prolonged contact with smart devices.

Implications:

• Awareness among clinicians and patients regarding device-induced nerve compression is crucial.
• Patients presenting with thigh paresthesia should be questioned about their use of portable electronic devices.
• Recommendations for device usage may need to be updated to prevent nerve entrapment syndromes.
