Summary
Carpal tunnel syndrome (CTS) can be unexpectedly caused by transverse muscular fibers in the carpal canal, found in 11% of patients. This finding is especially common in young male workers under 30, potentially explaining early CTS development.
Area of Science:
- Orthopedics
- Anatomy
- Surgical Pathology
Background:
- Carpal tunnel syndrome (CTS) is a common condition causing hand pain and numbness.
- The carpal canal is a narrow passageway in the wrist.
Purpose of the Study:
- To investigate the prevalence of transverse muscular fibers within the carpal canal in patients undergoing surgery for CTS.
- To determine if this anatomical variation is associated with early-onset CTS in specific patient demographics.
Main Methods:
- Retrospective review of 1,280 surgically treated carpal tunnel syndrome cases.
- Intraoperative assessment for the presence of transverse muscular fibers within the carpal canal.
Main Results:
- Transverse muscular fibers were unexpectedly found in 11% of the operated cases.
- A higher frequency of these fibers was observed in male patients under 30 years of age.
Conclusions:
- The presence of transverse muscular fibers is a significant, previously underreported finding in carpal tunnel syndrome.
- This anatomical anomaly may be a contributing factor to the early development of carpal tunnel syndrome in young male workers.
