Vibration-induced carpal tunnel syndrome

Area of Science:

• Orthopedics
• Neurology
• Occupational Medicine

Background:

• Carpal tunnel syndrome (CTS) is a common condition affecting the median nerve.
• Vibration tool use is a potential, though often overlooked, cause of CTS.
• Identifying and treating vibration-induced CTS (VI-CTS) is crucial for patient recovery.

Purpose of the Study:

• To investigate the outcomes of surgical intervention for vibration-induced carpal tunnel syndrome (VI-CTS).
• To explore the association between vibration exposure, CTS, and trigger finger.
• To evaluate the efficacy of median nerve decompression and trigger finger release in VI-CTS patients.

Main Methods:

• Retrospective review of 787 median nerve decompressions performed between 1976 and 1985.
• Identification of 42 cases potentially related to vibration tool use.
• Inclusion of 6 non-operated patients with confirmed VI-CTS, totaling 48 patients.
• Analysis of surgical outcomes for 65 median nerve decompressions and associated trigger finger releases.

Main Results:

• 42 of 787 surgical cases were potentially VI-CTS.
• All patients presented with classic CTS symptoms and positive electrodiagnostic tests (EMG/NCS).
• Median nerve decompression and/or trigger finger release yielded good subjective results in properly selected VI-CTS patients.

Conclusions:

• Median nerve decompression is an effective treatment for vibration-induced carpal tunnel syndrome.
• Trigger finger release may be beneficial in conjunction with median nerve decompression for VI-CTS.
• Proper patient selection is key to achieving favorable outcomes in VI-CTS treatment.
