      Zone IV

    Correct Answer
    B. Zone II
    Explanation
    The correct answer is Zone II. In the extensor tendon injury classification system, Zone II refers to injuries located over the middle phalanx, which is the bone in the middle section of the finger. Injuries in this zone can affect the extensor tendons that run over the middle phalanx, often leading to difficulty in fully straightening the finger.Treatment for Zone II injuries usually involves a combination of approaches, including:P/AA/Arom: This stands for passive, active-assisted, and active range of motion exercises. These exercises are designed to help maintain flexibility and mobility in the finger while the injured tendon heals. They should be performed under the guidance of a therapist.Dynamic splinting: This involves the use of a specially designed splint that helps support the injured finger while allowing some controlled movement. Dynamic splinting can help decrease tendon adherence and promote healing while minimizing the risk of stiffness or contracture development.A therapist may also provide additional treatment modalities and techniques based on the specific needs and circumstances of the patient.

      Is a possible MD treatment for injuries in either zone III or IV

    • B.

      Are indications of an Closed injury 

    • C.

      None of the above

    • D.

      All of the above

    Correct Answer
    A. Is a possible MD treatment for injuries in either zone III or IV
    Explanation
    The correct answer is "is a possible MD treatment for injuries in either zone III or IV." Immobilization in neutral or mild hyperextension for 4-6 weeks is a common treatment approach for extensor tendon injuries in Zone III or IV, which are located over the proximal interphalangeal (PIP) joint or proximal phalanx, respectively. Immobilization of the injured finger helps protect the healing tendon and maintain proper positioning during the recovery process. The finger is typically splinted in a neutral or slightly hyperextended position to minimize stress on the healing tendon and promote optimal function after recovery. This treatment approach allows the injured tendon to heal without the need for surgical intervention. After the immobilization period, hand therapy may be recommended to regain range of motion, strength, and flexibility in the finger. It is important to consult with a healthcare professional to determine the most appropriate treatment plan based on the specific circumstances of each patient, as individualized care is essential for optimal recovery.

      Full tendon gliding

    Correct Answer(s)
    A. Prevent infection
    D. Maintain and/or increase ROM
    E. Full tendon gliding
    Explanation
    The three general treatment goals for extensor tendon repair are:
    Prevent infection: Ensuring proper wound care and hygiene helps minimize the risk of infection, which can complicate the healing process and lead to poorer outcomes.
    Maintain and/or increase range of motion (ROM): Therapeutic exercises and splinting techniques aim to preserve or improve the flexibility and mobility of the injured finger, hand, or wrist. This is crucial for regaining normal function and preventing joint stiffness or contractures.
    Full tendon gliding: Achieving smooth and unrestricted gliding of the repaired tendon is essential for optimal function. Therapeutic exercises, scar tissue management, and splinting techniques are employed to promote proper tendon gliding and reduce the risk of adhesions or other complications.
    It is important to note that other goals, such as edema reduction and realignment of scar tissue, may also be important components of a comprehensive treatment plan, depending on the specific injury and individual patient needs.
