Monoaxial Screw

Specifications - Monoaxial Screw

Monoaxial Screw are used in a spinal fusion to add extra support and strength to the fusion while it heals. The screws themselves do not fixate the spinal segment, but act as firm anchor points that can then be connected with a rod.

Monoaxial Screw is specifically intended to provide internal fixation to stabilise and immobilise the spine. The screw is put into the vertebrae to encourage fusion, which is the process of connecting two or more vertebrae to form a solid bone mass.

Sizes and Uses of Monoaxial Screw

Monoaxial Screw made from titanium, come in a variety of shapes and sizes to meet the demands of the patient.
Diameters: 4.5mm, 5mm, 5.5mm, 6.5mm and 7mm.
Lengths: 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm and 60mm

Monoaxial Screw System intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine: degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture, dislocation, scoliosis, kyphosis, spinal tumor, and failed previous fusion

Monoaxial Screw are placed above and below the vertebrae that were fused. A rod is used to connect the screws which prevents movement and allows the bone graft to heal. After the bone graft grows, the screws and rods are no longer needed for stability and may be safely removed with a subsequent back surgery. Removal isn’t necessary unless they cause the patient discomfort.

Monoaxial Screws have transformed orthopaedic and spinal surgery by allowing for greater flexibility and adjustment during screw placement. Their ability to fit specific patient anatomy and optimise screw trajectory helps to increase fusion rates, stability, and spinal deformity repair. However, careful surgical planning, skill, and follow-up are required to maximise the advantages while minimising the hazards associated with these cutting-edge technologies.
