Glossary Term
Cancellous Screw
Definition
A Cancellous Screw is a type of orthopedic screw designed for fixation in the spongy, trabecular bone found in areas like the epiphysis of long bones. These screws have a wider thread and a smaller core diameter, providing better purchase and holding strength in the porous structure of cancellous bone.
Relevance to the MedTech Industry
Cancellous screws are essential for internal fixation in orthopedic surgeries, particularly for stabilizing fractures, reconstructing joints, and securing implants. Their design ensures effective anchorage in cancellous bone, facilitating proper healing and biomechanical stability.
