Lower limb deformities in children: two-stage correction using the Taylor spatial frame

The Taylor spatial frame is a new external ring fixation system developed for correction of axial, sagittal, planar and rotational deformities of the extremities. Between August 1999 and October 2000 five children were treated by this system. Four had shortened and deformed femurs after fracture, osteomyelitis or a congenital short femur. One patient had a pseudoarthrosis of the tibia. Mean corrections were leg lengthening 5.9 cm (1.7-7.2), valgus correction 10.6 degrees (0-19), lateral translation 12.6 mm (0-33) and rotation 10 degrees. The mean healing index was 48.4 days/cm. In all patients the bones fused without major complications. We recommend the Taylor spatial frame for corrections of complex limb deformities.
