title: Treatment of equinocavovarus deformity in a severely hemophilic child: the role of a monolateral multiplanar-geared fixation device.
abstract: Equinovarus deformity is associated with various disorders and diseases, including this case of recurrent hemarthrosis due to hemophilia. The patient demonstrated progressive deformation in the ankle and foot over the course of several years of evaluation. Until medical hemostatic control was possible, surgery was contraindicated. At age 9, therapeutic control of bleeding was attained, and surgical intervention was initiated. Due to concerns for skin and soft tissue compromise in this patient, a monolateral multiplanar-geared external fixator (M2 MultiPlanar MiniRail, Orthofix) was placed using two sets of half pins. The use of the M2 fixation device demonstrated its ease of use and application, along with the staged correction that was completed both in the orthopaedic office and at home. This case presents an effective approach to the surgical correction of equinocavovarus deformity using a monolateral multiplanar-geared fixation device.
