- Indications:
- for patients with hemivertebrae only and no kyphosis;
- age > 5 years (although some surgeons will perform this procedure on patients as young as 2.5 yrs);
- short curvature of less than 50-70 degrees involving < 6 or less vertebrae;
- Technique:
- epiphysiodesis and arthrodesis is performed both anteriorly and posteriorly on the convex side;
- this will allow growth on the concave side;
- convex 33% to 50% of vertebral end plates are removed and fused anteriorly, and only the convex half of the posterior spine is fused;
- some curve correction is achieved with a postoperative cast;
- postoperatively patients must wear a cast for 6 months;
- Results:
- modest correction may be achieved averaging 10 degrees
