Carpal arch alteration after carpal tunnel release
The Journal of Hand Surgery
|May 1, 1986
Summary
Postoperative widening of the transverse carpal arch after carpal tunnel release averages 10.4% or 2.7 mm. This arch widening directly correlates with reduced grip strength in patients.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Clinical Biomechanics
Background:
- Carpal tunnel release is a common surgical procedure.
- Postoperative changes in transverse carpal arch dimensions are not fully understood.
- Evaluating these changes may offer insights into surgical outcomes.
Purpose of the Study:
- To quantify the postoperative widening of the transverse carpal arch after carpal tunnel release.
- To investigate the relationship between transverse carpal arch widening and key functional outcomes.
Main Methods:
- Retrospective clinical study involving 50 patients.
- Measurement of transverse carpal arch dimensions post-surgery.
- Correlation analysis with postoperative pain, grip strength, forearm circumference, and wrist range of motion.
Main Results:
- Mean transverse carpal arch widening was 10.4% (2.7 mm).
- A significant direct relationship was found between arch widening and loss of grip strength.
- No significant relationship was observed between arch widening and residual pain, forearm circumference, or wrist range of motion.
Conclusions:
- Transverse carpal arch widening is a quantifiable outcome after carpal tunnel release.
- Increased arch widening is associated with diminished grip strength.
- Further research may explore the clinical implications of transverse carpal arch changes on hand function.

01:16Muscles of the Forearm that Move the Hand and Fingers
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...
