Flexor Tendon Repair

Concepts

 

1. Core suture

 

Strength of repair proportional to

A.  Number of strands crossing the gap (not suture type)

B.  Suture size (usually non absorbable braided suture 3/0 or 4/0)

 

2. Repair strength increases more rapidly with early motion stress

 

3. Dorsal sutures are stronger but may interfere with blood supply
