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

Mohammed A. A. Geith, Ahmed M. El. Naggar

Abstract


Background: Tibial deformity in childhood is not always one plane deformity, but often combines torsional and angular malalignment.

Methods: 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.

Results: 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. ‎ 

Conclusions: 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.
