title: Femoral deformity correction in children and young adults using Taylor Spatial Frame.
abstract: The Taylor spatial frame (TSF) has been used commonly in children and young adults. Its use in the tibia is more extensively studied and applied than in the femur. We asked whether normal alignment can be achieved with accuracy during correction of femoral deformities while avoiding major complications in children and young adults. We retrospectively reviewed the clinical and radiographic records of 20 patients (22 limbs), ages 5.9 to 24.6 years, who underwent a TSF for femoral deformity. Etiology included a number of diagnoses of the pediatric age. Minimum followup was 4.5 months (mean, 15.7 months; range, 4.5-35 months). The mean time in frame was 6.2 months (range, 2.6-19 months). Frontal and sagittal plane deformities were corrected to within normal values. A mean limb lengthening of 4.9 cm (range, 1.5-9 cm) was performed in eight femora in seven of which the limb length discrepancy was a secondary concern. External fixation index in the lengthening subgroup was 2.2 months/cm. The 15 complications in 13 limbs included pin tract infection, knee stiffness, delayed union, skin irritation, and posterior knee subluxation. No complications occurred in nine limbs. Computer-assisted femoral deformity correction with six-axis deformity analysis and the TSF is an accurate and safe technique in children and young adults.
