[Pathological fractures of the knee].
The authors present the methods and results of treatment of 20 epiphyseal and low-metaphysis pathological knee fractures treated at the Department of Orthopedics of the Lublin University of Medical Sciences between 1962-1999. The average age was 39 years. Malignant tumours (2 lymphomas, 1 plasmocytoma, 1 hemangiopericitoma, 2 adenocarcinoma metastases) and benign lesions (10 giant cell tumours, 3 solitary bone cysts, 1 intraosseous extension of pigmented villonodular synovitis) causes 18 femur fractures and 2 tibia fractures. The fractures caused by lymphomas in 2 patients and plasmocytoma in 1 patients were treated with either a plaster cast or skeletal traction and healed within 16 weeks. Tumour resection and reconstruction with Rush rods, Kuntscher nail, plate and methylmetacrylate were performed in 2 cases. In 1 case with hemangiopericytoma hip exarticulation was performed. In 5 cases pain relief and weight bearing capacity of the limb was not achieved because of neoplasm recurrences; 5 deaths occurred within 6 months to 7 years after femur fracture because of pulmonary metastases. Benign bone lesions were treated by curettage of pathological tissues, burring bony walls of the lesions and filling the cavities with bone grafts or methylmetacrylate (1 case). Displaced fragments were reduced whenever possible. Limbs were immobilised in plaster casts. The follow-up period for patients with benign lesions was 8 years. All fractures healed. Arthritis with persistent pain and knee contracture was noted in 1 patient who underwent surgery 3 times for giant cell tumour recurrences, complicated by infection and varus deformity.
