What does cancellous screw mean?
Cancellous Screws These screws have larger threads that provide more purchase in soft cancellous bone and therefore are more frequently used in the metaphyseal areas.
What is HCS screw?
The Merete® Cannulated HCS (Headless Compression Screws) are self-drilling/self-tapping, dual pitched screws with a threaded head which can be countersunk into the bone. The screws are available in diameters of 3.0 mm, 4.3 mm and 6.5 mm in various lengths.
What is an arthrex screw?
Arthrex carries an extensive line of both solid and cannulated metal screws in cortical, cancellous, and locking screw options. These screw are utilized for surgical fixation of fractures, fusions, and osteotomies.
What is a cancellous bone?
Spongy (cancellous) bone is lighter and less dense than compact bone. Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow. The canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply.
What is Malleolar screw?
3.5mm Malleolar Screw is designed to be used for fracture fixation of small fragments in cancellous bone. It is primarily used in interfragmental compression bone plates and used in hard cortical where buttress thread form provide enhanced pull-out resistance.
What is LCP plate?
The Locking Compression Plate (LCP) is a new screw-plate system that offers the possibility of inserting conventional and locking head screws into the specially designed combination holes. It represents a further development of the PC-Fix and the LISS and was released for clinical application in March 2000.
Which screw is better for ACL surgery?
Abstract. BACKGROUND: Graft fixation during anterior cruciate ligament (ACL) reconstruction can be achieved with use of either bioabsorbable screws or metal screws. Although bioabsorbable screws and metal screws have similar fixation strengths, bioabsorbable screws eliminate the need for removal.
What is a bioabsorbable screw?
Bioabsorbable screws are made from poly L-lactic acid (PLLA) and are absorbed by the body. This prospective, randomized study compared the safety and efficacy of the PLLA screw with that of the metal cannulated interference screw for anterior cruciate ligament reconstruction.
Where is the cancellous?
Cancellous bone is the meshwork of spongy tissue (trabeculae) of mature adult bone typically found at the core of vertebral bones in the spine and the ends of the long bones (such as the femur or thigh bone).
Where is cancellous tissue?
Cancellous tissue, also known as cancellous bone, spongy bone or trabecular bone, is characterized by its spongy, porous, honeycomb-like structure and is typically found at the ends of long bones. Compact tissue is also known as hard bone, compact bone or compact cortical bone.
What is a cancellous screw?
Cancellous Screw Cancellous screws consist of a thicker inner diameter with thinner threads that provide more purchase in cancellous bone, usually in the metaphyseal area. From: Case Competencies in Orthopaedic Surgery, 2017
When should surgical stabilization with cancellous screws be performed?
Surgical stabilization with cancellous screws should be urgently performed for young patients with a high-energy injury and good bone quality. This may also be performed after timely medical evaluation for highly functional elderly patients with good bone quality and minimal osteoarthritis.
How do you use a screwdriver with a cancellous bone?
The torque must not exceed the holding power of the threaded segment of the screw in the cancellous bone. Therefore, care must be taken to avoid maximal torque. When using a screwdriver, the surgeon may choose to use a tripod finger grip instead of a power palmar grip.
