Step-cut translation osteotomy and Y-plate fixation: A novel method for correction of cubitus varus and valgus deformity

Introduction: Many types of osteotomy have been proposed for the treatment of cubitus varus and valgus deformity. All these osteotomies have their advantages and disadvantages; however, till date there is no uniform consensus as to which osteotomy is the best suited for correction of these deformities. Materials and Methods: We reviewed the results of step-cut translation osteotomy in the management of cubitus varus and cubitus valgus deformity. This study includes 27 cases of cubitus varus and five cases of cubitus valgus deformity that underwent supracondylar step-cut translation osteotomy with Y-plate fixation for correction of the deformity. Results: The results were evaluated according to the modified criteria of Oppenheim et al. There were 25 excellent, six good, and one poor result. Overall, complication rate in our series was 12.5% (4/32). There was no recurrence of deformity in the available follow-up. Conclusions: Step-cut translation osteotomy is a relatively simple procedure that corrects cubitus varus and valgus deformities without any prominence of the medial or lateral condyle. Moreover, a wide osteotomy surface and rigid fixation allows early mobilization of the joint with good clinical results.
