Hypothesis
Can Guyon's canal syndrome be misdiagnosed as occupational overuse syndrome in computer users?
Conclusion
The study highlights the importance of nerve conduction or imaging studies to avoid misdiagnosis of occupational overuse syndrome.
Supporting Evidence
- The patient was misdiagnosed with ulnar nerve neuropraxia due to occupational overuse.
- Nerve conduction studies showed prolonged motor latency in affected muscles.
- Magnetic resonance imaging confirmed the presence of a ganglion in Guyon's canal.
- Symptoms resolved completely after surgical decompression of the canal.
Takeaway
A woman thought to have a typing injury actually had a ganglion causing her hand problems, and fixing it made her feel better.
Methodology
Case report detailing clinical history, nerve conduction studies, and MRI findings.
Potential Biases
Potential bias in initial diagnosis due to occupational history.
Limitations
The study is based on a single case, limiting generalizability.
Participant Demographics
54-year-old female secretary.
