Correction of genu recurvatum in poliomylitis by the ilizarov method

ABSTRACT

Mild Genu Recurvatum can cause some disability, but when quadriceps is severely weakened as in poliomyelitis, such a deformity is desirable. However severe genu recurvatum is significantly disabling. The Ilizarov apparatus was used to correct genu recurvatum in eight patients suffering from poliomyelitis using our new technique of pate liar block of the proximal tibia. In six cases, the genu recurvatum was entirely due to capsuloligamentous stretching resulting in posterior translation of the tibia whereas in two cases it was associated with osseous deformity. Preoperatively, the angle of recurvatum averaged 33.8° [23 to 42]. The average duration of external fixation was 4.8 month [3 to 7]. At the last follow-up, all patients, except one, had achieved an excellent or good radiological and functional outcome. Three patients suffered complications including, pin-track infection and Knee stiffness. Our results indicate that the Ilizarov apparatus is an effective tool for managing the deformity of Capsuloligamentous Genu recurvatum, with or without shortening
