Modified Oblique Proximal Tibial Osteotomy for Deformity Correction of Tibia Vara (Blount Disease)

Mohamed Mansour Elzohairy

Background: In Blount’s disease, there is a complex three-dimensional deformity which typically includes varus, internal rotation, and (sometimes) procurvatum. The best way to obtain correction is with simple procedure carried out as high in the tibia as possible to promote rapid union, quick remodeling, and with minimal proximal shaft deformity.
Patients and methods: 17 patients with tibia vara underwent corrections of deformity associated with tibia vara by modified Rab proximal tibial oblique osteotomy at our hospital. In twelve patients the deformity was bilateral and it was unilateral in the other five patients, with a total of 29 tibiae. They were ten boys and seven girls with a mean age at surgery of 3 years 6 months (range, 3 years 2 months to 4 years 11 months). The patients were in stage III of the Langenskiöld classification (1952) of the disease.
Results: According to Schoenecker’s criteria, 100% of the patients in this study had a good result. Radiologically healing was achieved in all osteotomies with the desired correction of deformity within twelve weeks in all the 17 patients with no complication.
Conclusion: The modified Rab oblique proximal tibial has the advantage of allowing both angular and rotational correction with a high degree of success.
