These devices are indicated as an adjunct to fusion for all of the following indications: degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies); spondylolisthesis; trauma (i.e., fracture or dislocation); spinal stenosis; curvatures (i.e., scoliosis, kyphosis, and/or lordosis); tumor; pseudoarthrosis; and failed previous fusion in skeletally mature patients.
Device Description
The M.U.S.T. Extension consists of the following implants that are to be used as part of the M.U.S.T. pedicle screw system (K121115): - New sizes (diameter and length) of the solid polyaxial pedicle screws that were cleared under K121115 - Solid and cannulated monoaxial pedicle screws - Cross connectors The M.U.S.T. Extension is intended to be used as part of the M.U.S.T. pedicle screw system for the stabilization and the fusion of the lumbar and thoracic spine. The M.U.S.T. Extension includes different sizes of screws and cross connectors. The screws are fixed in the pedicle and the vertebrae. The straight and pre-bent rods (K121115) act as a connector between the different screws to create a stable construct. The cross connectors act as a stabilizing construct between the rods on each side of the vertebrae. The cross connectors have an adjustable medial/lateral length in order to address various distances between the rods depending on the patient's anatomy. Rod distances from 35mm to 98 mm can be addressed with the various connector sizes. The connector offers an angular adjustable central joint in order to align the connection to the rod. The anqular adjustable feature as well as the size range of the connectors is within the range of the predicate devices. The M.U.S.T. Extension can be applied with the common surgical technique for posterior instrumentation. The M.U.S.T. Extension cross connectors are made of Titanium alloy (Ti6AI4V ELI -ISO 5832-3, ASTM F136) and come in 4 sizes: 35-42, 40-50, 48-66, and 64-98. The M.U.S.T. Extension pedicle screws are made of either Titanium alloy (Ti6Al4V ELI - ISO 5832-3, ASTM F136) or a combination of Titanium alloy (Ti6AI4V ELI - ISO 5832-3, ASTM F136) and CoCrMo (ISO 5832-12, ASTM F 1537). The M.U.S.T. Extension solid polyaxial pedicle screws have diameters of 8, 9, and 10mm and lengths between 20 and 100mm in 5mm increments. The M.U.S.T. Extension solid monoaxial pedicle screws have diameters between 4.5 and 7mm and lengths between 25 and 65mm in 5mm increments in addition to screws with a diameter of 8mm with lengths between 25 and 90mm. The M.U.S.T. Extension cannulated monoaxial pedicle screws have diameters between 5 and 7mm and lengths between 40 and 60mm in 5mm increments. The screw shaft is color anodized to simplify the identification of the screw diameter. The pedicle screw has a dual lead thread to simplify the screw insertion and reduce the number of turns. The threads are designed with a cylindrical diameter. The construct is secured using a set screw made of CoCrMo (ISO 5832-12, ASTM F 1537). The pedicle screws are available both in sterile and unsterile packaging while the cross connectors are available in sterile packaging.
