ABSTRACT
Introduction:
Paget's disease is a metabolic bone disorder characterized by abnormal patterns in bone remodeling, resulting in variable degrees of chronic bone pain, deformation of the long bones and rarely, and pathologic fracture. These issues can pose difficult surgical challenges, particularly in the elderly frail population, where the benefits of orthopedic intervention must be balanced with minimizing inherent surgical risks. Such considerations often include reducing operative time and blood loss, allowing for early mobilization, stabilizing an impending fracture, and providing symptom relief. Case Report A 77-year-old female with a 10-year history of Paget's disease presented to an outside orthopedic clinic with progressive right leg pain and worsening anterior bowing following minor trauma to the extremity. Ultimately, the patient was offered in situ prophylactic intramedullary (IM) nail fixation, intended to augment her bone's native strength and prevent further microfractures and subsequent deformation. A three-dimensional (3D) printed patient specific model was developed to permit for pre-contouring of an off-the-shelf implant and subsequent sterilization and use at a future point in time. She underwent uneventful IM nailing of her tibia with the pre-contoured implant and proceeded to progress clinically postoperatively.Conclusion:
In this report, we present an innovative use of a 3D printed patient-specific tibia model to pre-contour an IM nail. This surgical approach was undertaken to treat an elderly patient with a symptomatic and progressive deformity of the tibia secondary to Paget's disease of bone.
