primaLOK SP 12mm Implant Assembly, Sterile The Wenzel Spine primaLOK SP Interspinous Fusion System is a posterior, nonpedicle supplemental fixation device, intended for use in the non-cervical spine (T1-S1). it is intended for plate fixation/attachment to spinous process for the purpose of achieving supplemental fusion in the following conditions: degenerative disc disease (defined as ack pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), spondylolisthesis, trauma (i.e. fracture or dislocation), and/or tumor. The primaLOK SP Interspinous Fusion System is intended for use at one level with bone graft material and not intended for stand-alone use.
A sterile collection of small sheets of firm material and bone screws intended to be implanted onto fractured bone fragments to bridge and stabilize the fracture gap, and shield the site from stress as the bone heals; the components are made of a material that is not chemically degraded or absorbed by natural body processes (includes implant grade metal such as surgical steel, titanium alloy, or carbon fibre). Tools for implantation may be included. The device is typically used to treat traumatic or pathological orthopaedic fractures; it may also be used to temporarily augment bone following a lengthening procedure, or for arthrodesis (joint fusion).
