Modified dome shaped proximal tibial osteotomy for treatment of infantile tibia vara

Abstract

<p class="abstract"><strong>Background:</strong> Tibial deformity in childhood is not always one plane deformity, but often combines torsional and angular malalignment.</p><p class="abstract"><strong>Methods:</strong> In this prospective study, dome shaped osteotomy was performed in 36 tibiae in 24 patients. The osteotomy was held with K-wires and a plaster cast. The mean age at surgery was 5.5 years and the mean follow-up time was 30 months, range (24-42) months.<strong></strong></p><p class="abstract"><strong>Results:</strong> All osteotomies united and no compartment syndrome occurred. Postoperatively, one leg (2.7%) had temporary weakness of external hallucis longus muscle. Thirty five of thirty six legs had good clinical and radiological correction of alignment. Recurrent deformity was seen in one leg. ‎ </p><p class="abstract"><strong>Conclusions:</strong> Dome shaped osteotomy of the tibia is a simple, safe and effective method for correction of uni-planar varus deformity. For bi-planar deformities in childhood with infantile tibia vara we may need to step cut the lateral cortex to allow good bone contact to help in union with minimum morbidity.</p><p class="abstract"> </p>
