The Acumed Cannulated Screw System is intended for fixation of fractures, fusions, and osteotomies of large and small bones and consists of screws, washers, and accessories. The system comprises partially or fully threaded screw implants using a cancellous thread form.The partially threaded screws can be used to lag one bone fragment to another where the bone fragment is captured by the threads of the screw and pulled toward the fragment piece closest to the headed end of the screw. Fully threaded screws are intended to stabilize fractures where little to no compression across the fracture site is needed.
To accommodate a high variety of fracture patterns and varying patient anatomy, the 7.3 mm screws are available in lengths ranging from 30-150 mm, all of which can be used over a guide wire. Made of titanium alloy per ASTM F136, all screws and washer implants are available in sterile and non-sterile forms.
The 7.3 mm Cannulated Screw System features the largest diameter and longest lengths in the Cannulated Screw System family. This set is commonly used in the pelvis, hip, knee, ankle, and foot. Specific indications include: Femoral neck fractures, sacroiliac joint disruptions, tibial plateau and femoral intercondylar fractures, calcaneal fractures, talar fractures, ankle arthrodesis, subtalar arthrodesis, fracture of the distal femur, and fracture of the dorsal pelvic ring. The system offers short, long, and full thread forms in sizes ranging from 30-150 mm to address a range of fracture patterns and patient anatomy.
Additional sizes and diameters are currently being developed and will soon be available within this system.
