Taylor spatial frame versus ortho SUV for correction of lower limb deformities: A comparative study

Background: Deformity of long bones of lower limb leads to frequent gait and joint problems, in addition to the esthetic problems. Correction of such deformities proves to be a challenge due to spatial and soft-tissue considerations. Taylor Spatial Frame (TSF) and Ortho-SUV Frame (SUV) are two six axis correction devices which utilize the Ilizarov methods and allow easier correction of complex deformities. This study was performed to compare the efficacy of TSF and SUV for correction of lower limb long bone deformities. Materials and Methods: The Study was held at Sir Ganga Ram Hospital, New Delhi between January 2015 and November 2019. Twenty patients were included for each correction group. Assessment of correction was done in terms of rate and accuracy of deformity correction, lengthening index, total lengthening achieved, time in frame, assessment of ability to perform Activities of Daily Living, functional outcome using Association for the Study and Application of the Method of Ilizarov (ASAMI) score, and complications during treatment. Results: Both groups showed excellent correction of deformity in all planes and good functional outcomes. TSF group showed lesser incidence of joint stiffness as well as a shorter time in Frame. Pin site infection was the most common complication followed by major residual deformity. Conclusion: Both TSF and SUV provide excellent outcome in correction of complex spatial deformities of lower limb with high accuracy and good functional outcome. The TSF provides an advantage over SUV with reduced time in Frame, lesser joint stiffness and increased patient compatibility due to smaller frame size and reduced bulk as compared to SUV.
