[A rare anatomical condition causing carpal tunnel syndrome]
Handchirurgie
|January 1, 1977
Summary
A rare anatomical variant, an extra flexor digitorum sublimis muscle, caused carpal tunnel syndrome by splitting the median nerve. This unique cause of carpal tunnel syndrome has not been previously documented.
Area of Science:
- Anatomy
- Neurology
- Orthopedics
Context:
- Carpal tunnel syndrome (CTS) is a common condition.
- Median nerve compression at the wrist is the typical cause of CTS.
- Anatomical variations can contribute to or mimic CTS.
Purpose:
- To report a novel anatomical variant causing carpal tunnel syndrome.
- To describe the mechanism of median nerve splitting by an anomalous muscle.
- To highlight the importance of recognizing rare anatomical causes of CTS.
Summary:
- A case of carpal tunnel syndrome (CTS) is presented.
- The CTS was caused by an unusual anatomical variant: an additional flexor digitorum sublimis muscle.
- This muscle longitudinally split the median nerve, leading to CTS symptoms.
Impact:
- This finding expands the known etiologies of carpal tunnel syndrome.
- It underscores the need for detailed anatomical evaluation in refractory CTS cases.
- It contributes to the understanding of nerve entrapment syndromes due to muscular anomalies.
