Medicrea | PASS LP™



PolyAxial Spine System
Low Profile :

Marketed for the treatment of spinal pathologies (scoliosis, spondylolythesis, traum..) , the PASS LP™​ thoraco-lumbar fixation system allows to connect the rod at distance from the spine and to perform a 3D correction through progressive stress distribution on all anchorages thanks to the ST2R technique (Simultaneous Translation on 2 Rods).

Registration :

US clearance: YES

CE marking : YES


Connection at distance from the spine: The rod is connected in an easy way to the PASS LP™​ anchorages, on threaded polyaxial posts and flexible guides , with no need for complex rod persuaders. The PASS LP™​ anchorages design with polyaxial post design eases the rod connection
Load sharing: It distributes the load on all the fixation points and allows a gentle progessive correction thanks to the ST2R technique (Simultaneous Translation on 2 Rods)
Optimum safety *: The risk of back out or breakage is reduced by lowering constraints at the bone contact surface, thanks to the innovative design of the implants and the surgical technique
Surgeon-friendly: Compact, optimized Instrumentation is well adapted for the surgeon in the OR. Only one container for implants and two for instruments allow to cover all the type of indications **

* See legal notice

** Mechanical tests ASTM F1717/08RAP037




Full polyaxiality: This is the most complete range of polyaxial anchorages with screws , self-stable hooks/claws, sacral plates and iliac fixation

Connection at distance at the spine: The PASS LP™​ combines the advantages of a top loading system with the side connection of the rod, and offers simple solutions well adapted to all situations even the most challenging cases *
Lowest profile: the PASS LP™​ offers the lowest profile polyaxial spinal system on the market**
Complete range to cover all indications *: deformities (scoliosis, kyphosis,…), degenerative (DDD, spondylolisthesis), trauma, tumors, a system to cover all the indications

* See legal notice
** Profile comparison done by Precision Metrology, Milwankee, WI on November 2010, using standard rod connection. Measurement done from the top of the implant to the surface, with screw placed to maintain 100% of claimed polyaxial range
