The Taylor Spatial Frame (TSF) is an external orthopedic device used to treat fractures and correct limb deformities. The TSF is a hexapod device named after its inventor, Dr. Charles Taylor, an orthopedic surgeon. The fixator stimulates the growth of new bone and allows surgeons to accurately orient and align bones according to their specific anatomic location.
The Taylor Spatial Frame is a metal frame consisting of two rings connected by six struts. The frame’s structure permits adjustments to be made to each strut allowing them to be moved independently. The TSF also relieves stress on bones by distributing force through the frame. Surgeons can modify the shape and size of the frame to fit the anatomy and requirements of the affected limb.
- Injury/trauma to the upper or lower limbs
- Limb deformities
- Limb length discrepancy
- Bone and joint infections
- Joint stiffness disorders
- Acute fractures, mal-unions, or non-unions
Limb deformity correction alters affected bones in hopes of achieving normal length, alignment, and/or function. The surgeon records information about the bone deformity and then enters this information into a specialized software application. The software creates an image of the bone deformity and provides a plan consisting of adjustments to be made to the frame to properly correct the bone.
The Taylor Spatial Frame is fit around the limb and connected to the bone with pins or wires that extend from the rings through the skin and bone to the other side. After surgery, the patient is provided with a turning schedule for making gradual adjustments of the device. During this time new bone cells form and fill in the gap between the bone segments. Adjustments are halted when the desired length, alignment, and position are achieved and at this point the bone is allowed to mature and solidify. Typically about one millimetre of new bone growth is achieved each day the frame is in place. It is recommended that the frame be worn for four to twelve months to be most effective.
