The implementation of standards for deformity correction planning of axial deformities and leg length discrepancy in paediatric orthopaedics and posttraumatic cases have improved the results of postoperative alignment and joint orientation. A variety of externally and internally applicable devices have been developed for limb lengthening and deformity correction. One of the most recent developments is the Taylor Spatial Frame Fixator based on a hexapod system and a computer software for deformity correction. But little is published about clinical results using this sophisticated technique and its possible advantages over other traditional unilateral fixators or ring systems. In times of difficulties financing our health care systems, a surgeons choice for a comparatively costly system should be based on qualified data. The aim of the present study was to compare the results of deformity correction and limb lengthening using a Taylor Spatial Frame with those of other ring fixators or unilateral systems.

Between 1996 and 2004, 72 deformity corrections and/or limb lenghtenings have been performed on 52 patients with the unilateral Orthofix system (n=32), the Ilizarov system (n=22) and the TSF device (n=18). Statistical analysis showed a direct correlation between the healing index and the age at operation, as well as between the lengthening distance and the rate of complications. There were no significant differences of the healing index between all three fixators and the number of complications between the Ilizarov and TSF device, but the unilateral Orthofix fixator showed significantly more axial deviations during distraction osteogenesis.

The Taylor Spatial Frame is easier to handle than the Ilizarov fixator but did not show superior results in clinical use.
