Summary
Overtightened handcuffs can cause severe and permanent nerve damage, particularly to the superficial radial nerve. This prospective study highlights the risks of handcuff neuropathy, emphasizing the need for careful application.
Area of Science:
- Neurology
- Orthopedics
- Forensic Medicine
Background:
- Previous research on handcuff-related neuropathies is limited to retrospective studies or small case series.
- There is a need for prospective data on nerve injuries caused by overtightened handcuffs.
Purpose of the Study:
- To prospectively evaluate patients presenting with symptoms attributed to overtightened handcuffs.
- To determine the incidence and severity of nerve injuries, including superficial radial, median, and ulnar neuropathies.
Main Methods:
- A 27-month prospective study was conducted at a large urban teaching hospital.
- Clinical evaluation and electrodiagnostic testing were performed on 41 patients complaining of hand numbness, weakness, or paresthesias.
- Nerve injuries were assessed using electrodiagnostic tests.
Main Results:
- Electrodiagnostic testing revealed neuropathies in 22 superficial radial, 12 median, and 9 ulnar nerves.
- Superficial radial neuropathies showed the strongest correlation between clinical and electrodiagnostic findings, with some cases being severe.
- Median and ulnar nerve injuries were generally mild.
Conclusions:
- Handcuff-related injuries, especially to the superficial radial nerve, can be severe and permanent.
- Prospective evaluation confirms the risk of significant nerve damage from overtightened handcuffs.
- Clinical findings are consistent with electrodiagnostic results in identifying handcuff neuropathy.
