| Abstract |
1. Introduction Treatment of frequently multidimensional deformities of various etiologies is a challenge in orthopedic surgery. Full restoration of limb alignment including leg length correction is the goal of treatment. The Taylor Spatial Frame (TSF) is a software supported hexapod ring fixator, which allows for gradual and simultaneous multidimensional deformity correction, based on callusdistraction according to Ilizarovs principles. We retrospectively reviewed 34 consecutive cases of at least 3- dimensional gradual deformity corrections in the tibia and femur with the Taylor Spatial Frame regarding etiology and type of deformity, final results and complications. 2. Methods All cases of gradual deformity corrections with the Taylor Spatial Frame (TSF) between 2005 and 2018 were reviewed. Only cases with at least 3-dimensional corrections were included. Hence, 12 posttraumatic, 14 congenital and 8 cases of various etiology could be included in this study. There were 12 cases with 4-dimensional and 22 cases with a 3-dimensional deformity correction. Most of the cases included bone lengthening in combination with deformity correction in the frontal, sagittal or torsional plane. We treated 21 male and 13 female patients. Average age was 19 years at the time of surgery. 3. Results The mean time in the external fixator was 24 weeks. Finally the aim of correction could be achieved in all patients. Average follow-up was 85 weeks. Complications included temporary nerve lesion of the profound branch of the peroneal, which fully recovered after 4 months, 2 cases of insufficient bone formation at the site of the callus distraction, treated with cancellous bone grafting and plating. One osseus infection occurred and needed surgical debridement but consecutively healed well. Premature consolidation (of the fibula) occurred in 1 case. 30 out of 34 patients suffered from a superficial pin infection, treated with oral antibiotics. At final follow up all patients were satisfied by the result and had no ongoing treatment related problems. 4. Conclusion For multidimensional deformities in various etiologies the TSF serves as an ideal tool to fully restore the limb alignment by simultaneous gradual correction and limb lengthening. There might be temporary disadvantages due to the external fixation, nevertheless this is a temporary problem and is equalized by the advantages of the undoubtedly accuracy which is provided by this method. |
