| Summary: | Aims: Severe infantile Blount's disease can result in a challenging multiplanar deformity of the proximal tibia with intra-articular and metaphyseal components. We describe our results using the Taylor's spatial frame (TSF) for acute tibial hemiplateau elevation combined with gradual metaphyseal correction in patients with severe infantile Blount's disease with an associated physeal bony bar. Patients and Methods: Eight patients (ten knees) underwent tibial hemiplateau elevation and metaphyseal correction from 2012 to 2016. We undertook a retrospective case note and radiographic review of clinical and radiographic outcomes. The mean age at the time of surgery of was 11.7 years and the mean length of follow-up was 18.2 months. Results: Improvement in radiographic parameters was seen in all patients. The mean tibiofemoral angle improved from −28.3° to −5.9° postoperatively. The angle between femoral condyles and the tibial shaft improved from the mean of 56.3° to 90.3°. The joint depression angle was also seen to improve from the mean 47.4° to 9.8°. No significant complications were seen. Conclusion: This technique is effective in correcting the complex deformity encountered in severe infantile Blount's disease. Use of the TSF may provide certain advantages in comparison to previously described approaches. |
