Arthritis Recovery

The Digitalis PIP system is designed for arthroplasty of the proximal interphalangeal joint. It contains a silicone body device which is implanted using surgical procedure to replace the joint. When implanted, the Digitalis PIP restores natural flexion and extension movement to the affected finger. It ensures PIP joint mobility of between 0-70° and a 15° pre-flexion angle. The latter allows the device to respect normal finger positioning and avoid material overload.

The interphalangeal joints are essential to fine motor control of the fingers. The proximal interphalangeal joint allows for articulation between the proximal and middle phalanx of the hand. As such, any disruption or damage to the PIP joint can directly impact patient quality of life by preventing efficient gripping and pinching.

    Frequently Asked Questions

    Digitalis should be used for the treatment of severe arthritis in the hand. This includes rheumatoid arthritis, arthrosis, destroyed joint surfaces, ankylosed joints and joints with a limited range of motion. The system can also be used to treat joints that are non-functional due to bone misalignment.

    The main contraindications that surgeons must be aware of are:

    • Inadequate musculo-tendon and skin mass.
    • Inadequate bone stock.
    • Patient has an in-progress infection or active sepsis.
    • Significant stage bone demineralisation.
    • Inadequate neuro-vascular system.
    • Child patients.

    Those suffering from PIP joint arthritis typically present with swelling around the middle of the fingers. This is often accompanied by sensitivity and stiffness surrounding the joints, with both symptoms increasing in severity relative to one another.

    Rheumatoid arthritis symptoms can manifest in a range of upper and lower extremity joints. Of these, the most commonly affected are the joints in the hands, wrists, elbows, knees, ankles and shoulders. This includes the MCP and PIP joints.
