Limb Reconstruction Case Study
Can a severe external rotational deformity of the tibia be safely and effectively corrected using the new Orthofix rotation translation hinges?
by Mohi El-Shazly
A 36 year old patient presented with bilateral anterior knee pain. He had had multiple operations to improve patellar tracking on the right side with no success and ended up with a patellectomy and a custom-made trochlear resurfacing prosthesis. He now wanted the left knee dealt with.
On examination he was found to have severely squinting patellae.
Examination of his left hip for range of motion showed 55 degrees of internal rotation and 5 degrees of external rotation indicating severe anteversion of the femoral neck. A Sheffield Ring Fixator was applied, a fibular and percutaneous low energy tibial osteotomy were performed and gradual correction of the external tibial torsion was performed using the new rotation translation hinges.
