| Description | Introduction: The aim of the study is to assess sizes of distal part of the femur and proximal part of the tibia for extendable endoprosthesis of the knee joint in children. Methods and material: The authors performed radiological study of distal part of the femur and proximal part of the tibia in 300 patients in which X-ray was focused on the knee joint. There was a 1. group 6-10 years of age and 2. group 11-15 years. They meassured the biggest distance of distal metaphysis of the femur in AP and lateral view (A,C) and the biggest distance of proximal epiphysis of the tibia in AP and lateral view resp. (B,D). They meassured another group with 200 (1. group 6-10 years, 2. group 11-15 years) patients in which X-ray was focused on the diaphysis of the femur with AP view of the isthmus of the femur. Results: In calculation for both genders there were following values: 1. group A 74 mm, B 65 mm, C 51 mm, D 42 mm a E 9,0 mm and 2. group A 90 mm, B 83 mm, C 67 mm, D 58 mm and E 10,7 mm. The authors compared these results with data from anthropometric studies. Discussion: The authors achieved basic requirements for sizes of components of extendable endoprosthesis: 1. group femoral component of maximum of 50x40 mm, tibial component 45x30 mm, 2. group femoral component of maximum of 65x45 mm and tibial component 60x40 mm. The sizes will be tested in preclinical study on anatomical models. |
