A 10-year-old boy has a post-traumatic leg length discrepancy of 5 cm with angular deformity of the tibia (valgus 15°). The preferred method for simultaneous LLD correction and angular correction is:
- A Ipsilateral femoral shortening + tibial stapling
- B Tibial corrective osteotomy with casting and contralateral epiphysiodesis
- C Limb shortening osteotomy of the longer limb with supramalleolar tibial osteotomy
- D Ilizarov circular external fixator with hexapod (Taylor Spatial Frame) for simultaneous distraction and angular correction ✓
Explanation
The Taylor Spatial Frame (TSF) is a computer-assisted hexapod external fixator that allows simultaneous correction of limb length, angulation, translation, and rotation through software-calculated strut adjustments. It is the most versatile tool for complex multiplanar deformity correction with concurrent limb lengthening. The Ilizarov/TSF system is particularly suited to young patients with growth remaining where shortening of the contralateral limb would sacrifice normal bone. Simple circular Ilizarov frames can address angulation and LLD but TSF provides more precise multiplanar control.
