Sumario:The treatment of Blount's disease has historically remained controversial. All the described techniques for its treatment have their own advantages and disadvantages, and no consensus has been reached on a single surgical approach. The aim of this report is to share the early results of a combination technique in which we have collated three well-known surgical steps in one procedure. This combined procedure is indicated for severe and recurrent cases. Our ‘three-in-one’ technique combines an intra-epiphyseal plateau elevating osteotomy with a tibial metaphyseal osteotomy and a lateral tibial temporary hemi-epiphysiodesis. We also report initial results of three limbs in two patients who were treated using this technique. The first case was that of an adolescent with severe left Blount's disease (Langenskiold stage IV) and a lateral thrust. The second case was that of bilateral severe infantile Blount's disease (Langenskiold stage V) and the infant had a lateral thrust. All measurements remarkably improved in both patients during the post-surgical assessment. The limb length discrepancy was 0.6 cm in the first case and 0.5 cm in the second. The preoperative internal tibial rotation and lateral thrust were corrected spontaneously. No complications were recorded in either patient. The three-in-one technique is a safe and versatile surgical approach that can be used in severe, refractory, and recurrent cases of open physis. Furthermore, it can potentially solve the problems of lateral thrust and internal tibial rotation. More cases should be studied before we can endorse the safety and effectiveness of this technique.
