Background. Temporary hemiepiphysiodesis using 8 plate guided growth has gained widespread acceptance for the treatment of paediatric angular deformities. This study aims to look at outcomes of coronal lower limb deformities corrected using temporary hemiepiphysiodesis over an extended period of follow up. Methods. A retrospective analysis was undertaken of 56 children (92 legs) with coronal plane deformities around the knee which were treated with an extraperiosteal 2 holed titanium plate and screws between 2007 and 2015. Pre and post-op long leg radiographs and clinic letters were reviewed. Results. The mean age was 11.9 years (range 3 to 16) with a mean angular deformity of 12.3 degrees (5.1 to 33.5). The mean rate of correction was 0.8 degrees per month. Isolated distal femur correction occurred at a mean rate of 0.6 degrees per month (0.2 to 1.4) and isolated tibia at a rate of 0.5 degrees per month (0.0 to 1.7). Children treated with concurrent treatment of both femur and tibia corrected at a rate of 1.4 degrees per month (0.1 to 2.7). Similar rates of correction occur in children aged 10 and over compared to those younger than 10 (0.8 degrees per month compared to 0.7). We also saw similar rates of correction with extended follow up. The average rate of correction over the first 9 months post op was 0.8 degrees compared to 0.6 degrees over the following 10 months. Conclusion. This study is the largest long term follow up of 8 plate hemiepiphysiodesis which highlights the rate of correction in all age groups. Implications. With this knowledge surgeons can make a more informed decision regarding placement of hemiepiphysiodesis plates and length of time required for correction of angular deformities. It may also lead to consideration of alternative, more powerful techniques if the rate of correction is insufficient. Conflict of Interest: None declared

Aims

The management of a significant bony defect following excision of a diaphyseal atrophic femoral nonunion remains a challenge. We present the outcomes using a combined technique of acute femoral shortening, stabilized with a long retrograde intramedullary nail, accompanied by bifocal osteotomy compression and distraction osteogenesis with a temporary monolateral fixator.

Patients and Methods

Eight men and two women underwent the ‘rail and nail’ technique between 2008 and 2016. Proximal locking of the nail and removal of the external fixator was undertaken once the length of the femur had been restored and prior to full consolidation of the regenerate.
