摘要： An orthopedic implant device and method is disclosed. Specifically, a knee mold system is disclosed, including elastic tibial and femoral molds, each of which may be configured and dimensioned as a unitary mold for in situ placement during a surgical procedure. Each mold may be manufactured from an elastic material that may be disposable. The tibial mold may further comprise a sidewall forming a cavity, markings for relative depth measurement, and depth rings for use as a guide for scoring, cutting, and/or trimming and tearing away an excess portion of the tibial mold. The femoral mold may further comprise a sidewall defining a cavity, two legs extending from a body of the femoral mold for forming the artificial condyles, and an eyelet for aiding in placement and removal of the femoral mold. The resulting prosthetic tibial and femoral components may form an articulation surface that mimics, at least in part, the natural articulation surface of the knee.

摘要： A pedicle screw and rod assembly is provided which has a low profile in the final position. The pedicle screw includes a screw having a threaded portion and a head portion. A tulip body is positioned on the head portion of the screw. A tulip saddle is coupled to the tulip body and positioned to retain the tulip assembly on the pedicle screw. Wedge members are inserted in between the tulip body and the tulip saddle, causing the saddle to compress and thereby retain a rod within the tulip assembly. Colored wedge members alert a surgeon as to whether the system is in a locked or unlocked state. The top of the tulip assembly is approximately equal in height to, or lower than the rod itself. This provides a low profile pedicle screw and rod assembly since the rod itself will be the uppermost member of the completed assembly.
