LBN – proximal humerus nail
Locking Blade Nail
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.
Blade Fixation Screws
The blade fixation screws hold the blade in position over the lateral cortex and the nail.
PEEK insert
Provides secure fixation of the screw in the nail.
Blade/ triangle of forces
Provides secure fixation of the screw in the nail.
Distal nail diameter
Tapering of the nail to 6.5 mm at the distal end for easier insertion of the nail in tight medullary canals.
Anterior chamfer
Head locking screws
The 5.0 mm head locking screws provide a secure fit in the humeral head, even without a blade
Modular washer
The modular washer provides a secure, form-fitting transmission of forces to the cortex. Additional suture holes offer the possibility to fix the rotator cuff.
Material
Titanium, anodization type II
