USS II: cross-links
Cross-link connectors are transverse stabilizers linking the two longitudinal rods. They are recommended for unstable fractures and multi-segmental constructs in thoracic and lumbar spine and posterior spinal deformity correction and stabilization. The 3.5 mm rods can be bent according to anatomy. Together with the cross-links, they absorb the transversal forces and prevent parallel displacement of the spinal rods, which increases the stiffness of the construct. The new cross-links minimize tissue irritation due to a profile 2 mm lower than existing cross-links. The cross-link connectors can be assembled in various combinations. An easy click-on mechanism allows to preassemble a cross-link construct which is then placed on the two longitudinal rods.
The Holding Sleeves and Nuts are new parts of the USS II which is indicated for the correction and stabilization of the spine. Placement of the Nut and Holding Sleeve for 5 mm or 6 mm rods on hooks or screws is now possible in one single step. The holding sleeve is to be used in combination with the existing straight-handled socket wrench.
The Ti low profile transconnector is used to create a stable construct and to reduce rotation in thoracolumbar spine. The transconnector is preassembled and compatible with the USS instrumentation. Three additional sizes with lengths of 3338 mm, 3848 mm, and 4969 mm provide more options. For the selection of the optimal span length, a gauge is now available.
