Hand (Tendon), Reading: Primary Flexor Tendon Repair in Zone 1 and 2…

- - - - [Healing occuring from the outside of the tendon through scarring]
        
        Through cells extrinsic to the tendon through fibroblastic response from surrounding tissues (from surround, through scarring/adhesions)
      - How
        
        3 Phases (overlapping phases are predictable and sequential)
        
        1. Inflammatory phase (Early phase)
        
        Early fibroplasia phase of tendon healing (when the tendon is at its weakest and collagen is just beginning to be laid down at the repaired site)
        
        This phase is also the time when adhesions begin to occur
        
        48 to 72 hours
        
        2. Proliferative/ Fibroplasia phase (Intermediate phase)
        
        During which tendon repair gain tensile strength
        
        Period of 4 weeks to 7/8 weeks after repair
        
        3. Late phase (Remodeling/Maturation phase)
        
        Tendon repair continues to gain tensile strength and begins to remodel in alignment with the tension placed on it
        
        Includes the period from week 7 or 8 to 12 weeks after repair
        
        Considered to have nearly full tensile strength at 12 weeks after repair
    - - [Healing happening within the tendon itself]
        
        Healing of tendons in isolated, cell-free environment
      - How
        
        By nutrition direct from blood supply via the vincula
        
        By diffusion of nutrients in the synovial fluid that surrounds the tendons as they run under the pulley system
