The authors present a retrospective study of the T-Screw bone fixation device and its use for rigid fixation of osteotomies, arthrodesis, and fractures in foot surgery. The following is a discussion of 395 procedures in which the T-Screw was used for fixation. The results of the data confirm that there are specific advantages when using the device.
We have attempted to demonstrate the different healing patterns of cancellous and cortical bone and show how fixation devices impact healing. The incidence of hypersensitivity reactions, migration, and malignancy associated with fixation devices may be more prevalent in podiatric surgery than previously thought.
The T-Screw was patented in 1984. A 5-year study was begun in 1980, and FDA approval was granted in 1985. Detailed results of this clinical study will be reported in a later paper. The purpose of this paper is to introduce the device. The authors have found that early return to normal function and wearing shoes has been possible when using T-Screws for fixation of podiatric osteotomies. The screw appears to accelerate bone healing and has numerous applications throughout the foot. The authors believe that its ease of application and removal as well as its ability to generate rigid, compressive fixation makes it an excellent alternative to current fixation devices.
