The screw utilizes the superelastic properties of Nitinol to allow higher levels of compression than contemporary bone screws. During manufacturing, the screw is stretched and held in an elongated position with a pin.
Once physicians implant the device into the patient, the pin can be removed. The screw then attempts to shrink to its original length, causing the desired compression in the bone.
“Bone is a living material that remodels with altering stress levels, changing shape and mechanical properties. The dynamic healing process of bone warrants a dynamic implant material. The dynaMẌ™ Nitinol Compression Screw represents the next generation of screw fixation technology as it is engineered to change shape in vivo, enhancing fracture reduction while applying controlled compression to the fracture site,” said Matthew Fonte, PhD, founder and president of MẌ Orthopedics.
