Although not as common as femoral shaft fracture, supracondylar-intercondylar fracture of the femur present considerable challenges in management. Severe soft tissue damage, comminution, and intraarticular extension of fracture lead to unsatisfactory results in many cases, regardless of the adequate treatment. So recently, early anatomical reduction, rigid internal fixation and early exercise of the knee joint was recommended. From July 1986 to January 1992, the clinical result of 40 cases of supracondylar-intercondylar fractures of the femur treated by internal fixation weie evaluated after minimum follow-up of lyear according to the rating system of Neer et al. The results were as follows; 1. The most common cause of these fractures was traffic accident and the prevalent age was between 30 and 49 years old (57.5%). 2. According to AO classification, type A was 5 cases, type B in 1 case, type C in 34 cases and the average time to fracture consolidation was 15.4 weeks. 3. According to Neers criteria, excellent were 11 cases, satisfactory in 13 cases, unsatisfactory in 11 cases, and failure in 5 cases. 4. The complications were delayed union & nonunion of 8 cases, deep infection due to open fracture of 3 cases, and range of motion below 90° of 19 cases (47.5%). 5. Finally, the results of treatment depend on early anatomical reduction, rigid intemal fixation, early exercise of knee joint.
