Abstract

Fracture of intercondylar eminerce of the tibia indicate probable alteration of the cruciate ligament stability in the knee and occur from hyperextension injury of the knee and violent internal rotation of the tibia. Fracture of intercondylar eminence of the tibia has been classified by Meyer and Mckeever(1959, 1970) according to the degree of displacment and this classification is important as it pertains to the proper selection of treatment. The author studied 24 cases in 24 patients of fracture of the intercondylar eminerce of the tibia at the Department of Orthopedic Surgery of Severance Hospital during a 10 year period from Januaary, 1975 until December, 1984. The aim of this study was to find out incidence, cause and associated injury of the fracture of the intercondylar eminece of the tibia and was to asses the comparative results of the conservative and surgical treatment. The result of this study ase as follows ; 1. There is a predisposition for make in a ration of 3:1 and there is no age preponderance in occurance. 2.Majority of cause of injury was traffic accident(62.5%). 3.Isolated fracture of intercondylar eminence of the tibia was 15 cases (62.5%) associated knee joint injury shows 9 cases (37.5%). Among the associated knee joint injury, rupure of medial collateral ligament was 4 cases(44.4%), rupture of medial meniscus was 3 cases(33.3%) and rupture of lateral colateral ligament was 2 cases (22.2%). 4.By Meyer and Mckeever's classification, Type 2(41.7%) fracture of intercondylar eminence of the tibia was most common, and then Type 1(37.5%) and Type 3(20.8%) occured in order of frequency. 5. Type 1 and Type 2 fracture of the intercondylar eminence of the tibia resulted in good prognosis with only conservative treatment, and open reduction is not indicated. 6. Type 3 fracture of the intercondylar eminence of the tibia can be treated with conservative treatment if there is no associated injury of the knee joint.
