Various radiological parameters are used to evaluate a flatfoot
deformity and their measurements may differ. The aims of this study
were to answer the following questions: 1) Which of the 11 parameters
have the best inter- and intraobserver reliability in a standardized
radiological setting? 2) Are pre- and postoperative assessments
equally reliable? 3) What are the identifiable sources of variation? Measurements of the 11 parameters were recorded on anteroposterior
and lateral weight-bearing radiographs of 38 feet before and after
surgery for flatfoot, by three observers with different experience
in foot surgery (A, ten years; B, three years; C, third-year orthopaedic
resident). The inter- and intraobserver reliability was calculated.Aims
Patients and Methods
Modular endoprostheses today represent a standard treatment option in the management of musculoskeletal tumors of the lower extremities. Long-term results of these reconstructions, however, are often limited by the course of the underlying disease. We therefore report our experiences in cancer patients with megaprostheses of the lower limb after a minimum of 15 years. 62 patients, 34 men and 28 women, with a mean age of 26 years (median, 20; range, 6–83) were included in this investigation with a mean follow-up of 230 months (median, 228; range, 180–342). Endoprosthetic reconstructions of the proximal femur (11), the distal femur (28), the total femur (2) or the proximal tibia (21) were indicated for osteosarcoma (43), chondrosarcoma (5), malignant fibrous histiocytoma (3) or other tumors (11). All patients have received either a KMFTR (22) or a HMRS (40) modular prosthesis; 23 patients had a muscle flap, 14 had a fibular transposition osteotomy and 4 have received an artificial LARS ligament for soft-tissue reconstruction.Background
