| Popis: | Introduction: Fibrous dysplasia is a rare benign disorder of the skeletal system characterized by fibro osseous proliferation with intervening areas of normal or immature bone in the intramedullary region. It can either be a monostotic (involves one bone) or a polyostotic (involves more than one bone) presentation and usually occurs equally in males and females. Deformities like scoliosis and shepherd’s crook deformity are frequently encountered in the polyostotic form. We report a rare managed case of bilateral non-union of the pathological fracture of femur neck with shepherd’s crook deformity of the proximal femur in a case of polyostotic fibrous dysplasia. Case Report: A 16 years old female case of polyostotic fibrous dysplasia had bilateral Shepherd’s crook deformity of the proximal femur with bilateral non – union of pathological fracture of neck femur. We managed each side in one stage with two osteotomies. On the right side, first oblique osteotomy was done from just distal to the greater trochanter up to the level of the neck and the second; lateral closing wedge abduction osteotomy was done at the subtrochanteric level. 2 months later on the left side double lateral closing wedge abduction osteotomies were performed both at the subtrochanteric level. Fixation of both the sides was done using a 135° Dynamic Richard’s screw with a long side plate to span the osteotomy sites and the lesion. Post – operatively we achieved a neck shaft angle of 135° on right side and 133° on the left side. Follow up imaging showed union at both the osteotomy sites bilaterally and also at the site of the pathological fracture of neck femur. Presently, at 18 months post – operatively, patient is walking full weight bearing without support and there are no signs of recurrence of lesions of fibrous dysplasia or the deformity. Conclusion: Double osteotomy is an easy and effective method to correct the shepherd’s crook deformity and achieve correct mechanical alignment. Dynamic hip screw with long side plate is a versatile implant to tackle the proximal femur deformity. Double osteotomy corrects the deformity and tackles the associated problems like non - union of the pathological neck femur fracture in one stage. |
