Stable fracture fixation is key for fracture healing and regaining mobility.

 

Axial stability with intramedullary nailing

 

Intramedullary nailing is a well-accepted method for stable treatment of fractures of the long bones, i.e. upper leg, lower leg and upper arm. Intramedullary nailing involves inserting a metal rod into the hollow middle part of the fractured bone (the "intramedullary canal") in order to splint the fracture until healing occurs.

 

The nail itself provides axial stability, i.e. prevents sideward movement of the bone fragments. Additionally, the locking bolts placed at the extremities through the bone and the nail ensure rotational stability and maintain the length of the bone. The bolts and holes in the nail are not a tight fit, which can lead to slight toggling of the nail, i.e. the fixation is not angular stable.​​​​​​​​​​​​​​​​​​

 

ASLS - A new key technology for angular stability

 

The Angular Stable Locking System (ASLS) offers angular stability for screws used in combination with an intramedullary nail. ASLS is especially indicated in cases requiring a high degree of stability (e.g. in patients with poor quality bone, or for fractures close to the end of long bones).

 

The Angular Stable Locking System works like an anchor with a screw. The dowel, or sleeve, is inserted into the nail together with the screw. The expansion during screw insertion results in a tight fit and prevents toggling between nail and screw.

 

Thanks to the enhanced and controlled fracture fixation with ASLS, the patient can start weight-bearing early and will quickly restore its mobility and independence.​​​​​​
