Locking Blade Nail with patented blade support

Intramedullary nail osteosynthesis of the proximal humerus

The patented triangle of forces between nail and blade makes the LBN system from Marquardt Medizintechnik unique. The Locking Blade Nail achieves a higher primary stability due to the additional blade support on the medial column. The blade is also a support for the calotte fragment during abduction.

Secure fixation of humeral fractures

Flexible concept

The nail can be used with or without an additional blade. An integrated screw lock made of PEEK fixes the screw in the nail and prevents implant loosening.
