Flexor tendon gliding in the hand. Part II. Differential gliding
The Journal of Hand Surgery
|July 1, 1985
Summary
Three finger motions maximize flexor tendon gliding. These movements ensure optimal differential gliding of the superficialis and profundus tendons within the flexor sheath and against bone.
Area of Science:
- Orthopedic surgery
- Hand therapy
- Biomechanics
Background:
- Flexor tendon gliding is crucial for maintaining hand function after injury.
- Understanding tendon mechanics is essential for effective rehabilitation protocols.
Purpose of the Study:
- To identify specific finger motions that promote optimal flexor tendon gliding.
- To analyze differential gliding between superficialis and profundus tendons.
Main Methods:
- In vivo study involving 48 human hands.
- Analysis of three distinct finger motion patterns: straight-fist, hook, and fist.
Main Results:
- Specific finger motions were identified to provide maximum differential gliding.
- Optimal gliding achieved for superficialis and profundus tendons relative to each other, sheath, and bone.
Conclusions:
- The straight-fist, hook, and fist motions are key for maximizing flexor tendon gliding.
- These findings can inform therapeutic strategies for flexor tendon injuries.
