medi 4C – Hyperextension Brace with Ratchet-Closer

The medi 4C is a hyperextension brace designed for stabilization and immobilization of the thoracic and lumbar spine following fractures, post-operative recovery, and inoperable spinal tumors. The stable framework construction provides sagittal plane stabilization, rotational restriction, and lateral flexion control.

Equipped with a ratchet-closer system for easy handling and secure fit adjustment, the medi 4C allows for precise three-dimensional customization. Made from waterproof materials, it ensures durability and long-lasting performance.

Adjustment Instructions:

Adjusting the Width:

1️⃣ Loosen the four Allen screws on the chassis.
2️⃣ Adjust the orthosis to match the patient’s body width, ensuring a flat and secure fit.
3️⃣ Retighten the screws securely.

Adjusting the Upper Angle:

1️⃣ Loosen the two upper screws and adjust the angle so the extension pads rest just below the clavicle.
2️⃣ Retighten the screws securely.

Adjusting the Length:

1️⃣ Remove both side pads and loosen the screws on the lateral chassis.
2️⃣ Adjust the orthosis to the patient’s body length.
3️⃣ Move the chassis up or down at the connecting sites to match the level of the spinal lesion.
4️⃣ Do not bend the lateral frame sections—only the upper chest rod and pelvic clasp should be adjusted.
5️⃣ Cut the padding to the required length and secure it with Velcro.
6️⃣ Tighten the chassis screws.

Adjusting the Extension Pads:

1️⃣ Loosen the screws to adjust the height and angle of the extension pads.
2️⃣ Ensure the central chassis does not touch the sternum.
3️⃣ Tighten the screws securely.

Adjusting the Lower Angle:

1️⃣ Loosen the two lower screws and adjust the symphysis pad to fit the patient’s body contours.
2️⃣ Ensure the pad is not too low so that the patient can still sit upright.
3️⃣ Tighten both screws securely.

Closing the Buckle:

1️⃣ Fold back both buckle closers.
2️⃣ Insert the strap ends into the clip openings from the back, allowing them to emerge from the front.
3️⃣ Open the clasp to 90 degrees, then close it to tighten the strap securely into hyperextension.
4️⃣ Do not force close the belt—press both buckles firmly once in the desired position.
5️⃣ If needed, shorten the strap with scissors and smooth the ends.

Opening & Removing the Brace:

✔ Fold back one buckle only to remove the brace.
✔ Avoid bending the buckle excessively to prevent damage.

medi 4C Cliplock – Alternative Secure Closure System

Setting the Belt Length:

1️⃣ Adjust the belt length using Velcro fasteners and guide loops.
2️⃣ Ensure the compression pad is centered on the back.
3️⃣ Cut the side padding to fit, ensuring no overlap between the compression pad and the side padding.

Closing the Cliplock:

✔ Fold back the buckle and press it downward until it is fully locked.
✔ Ensure the clip is securely closed before wearing.

Additional Recommendations:

✔ Check the brace function and fit the day after initial fitting and make any necessary adjustments.
✔ For optimal comfort, wear a T-shirt underneath the brace.
