The Moss Miami procedure involves the usage of a versatile hook, screw and rod system which utilizes polyaxial screw technology and a patented dual closure mechanism with six points of contact with the rod. Moss Miami is available in stainless steel and titanium with a variety of rod diameters:
- Stainless steel technology of 4.0, 5.0, 6.35
- Titanium technology of 5.5 and 6.35
- Polyaxial and monoaxial srews
- Reduction screws and hooks
- Sacral connectors
Why moss Miami is used?
Moss Miami is a surgical treatment to treat adolescent idiopathic scoliosis. It presents metallurgical and biological attributes like other currently used posterior systems. It has other advantages also like
- Low profile implants
- Smaller rod diameter
- Top opening implants providing straight forward rod placements
- A simplified and strong closure mechanism
- Different hook styles
- Pedicle screws
The Moss-Miami system average correction of the Cobb angle of the coronal plane is obtained for more than 50 percent. The ability to maintain or correct physiologic sagittal contours of the spine is the major advantage of this system.
Results of some case studies:
The patients whose spinal dislocation was corrected through Moss Miami system were evaluated for curve correction, spinal balance and complications. Cob method was used to evaluate the spinal deformities and it was found that after doing an anteroposterior and lateral bending radiograph were evaluated of right thoracic curves. Hence this method is quite effective.
Through Moss Miami pedicular system or posterior instrumentation, it was seen that after placing screws at T2 and L2, there was a correction of 72% in every patient.
Conclusions:
It can be successfully concluded that frontal and sagittal thoracic curve correction of thoracic scoliosis can be successfully obtained through Moss Miami transpedicular instrumentation. Control of three columns of the spine provides sufficient apical translation and coronal realignment using transpedicular screws.
