    Summary
    This summary is machine-generated.

    To reduce tension on flexor tendon repairs, position the injured finger with the metacarpophalangeal joint flexed and adjacent fingers extended. This technique aids healing and preserves joint mobility for better functional recovery.

    Area of Science:

    • Orthopedic Surgery
    • Hand Surgery
    • Tendon Repair

    Background:

    • Flexor profundus acts as a unit, meaning tension on one part affects the whole muscle.
    • Suture line tension is a critical factor in flexor tendon healing and outcomes.

    Purpose of the Study:

    • To describe an optimal positioning strategy for flexor profundus tendon repairs.
    • To minimize tension on the suture line during the healing phase.

    Main Methods:

    • Positioning the injured finger with the metacarpophalangeal (MCP) joint flexed and interphalangeal (IP) joints extended.
    • Simultaneously extending the adjacent fingers to create muscle redundancy.
    • Splinting adjacent fingers in full extension for up to three weeks if necessary.

    Main Results:

    • This positioning strategy effectively reduces tension at the flexor profundus suture line.
    • The described finger position promotes preservation of joint mobility.
    • It provides an ideal environment for restoring movement after flexor tendon repair.

    Conclusions:

    • The MCP flexion with IP extension position is optimal for flexor profundus tendon repair.
    • This technique facilitates healing by minimizing suture line tension.
    • It supports early mobilization and improved functional restoration of the repaired tendon.
