Korreliert der Grad der Dislokation mit dem Therapieverfahren bei suprakondylären Humerusfrakturen im Kindesalter?

Hundred and twenty-eight supracondylar fractures of the humerus were studied retrospetively after an follow-up time of 4.3 years (1 to 17.8 years). In 87 cases (68%) the operative procedure was the closed reduction and percutaneous crossed-pin fixation for 19 fractures type III (56%), 22 fractures type II (76%) and 46 fractures type I (85%), whereas 41 fractures were treated by open reduction and crossed-pin fixation. The findings were evaluated according to “Flynn’s criteria” leading to the following results: “excellent” 77 times (60.2%), “good” 44 times (34.4%) “fair” 3 times (2.3%) and “poor” 4 times (3.1%). Our results show that with approximately 50% of all fractures type III the treatment by closed reduction and percutaneous crossed-pin fixation leads to a very good long-term result. On the other hand, rotated or interponated fractures type I and II require an open reduction and crossed-pin fixation. Independent of the type of fracture, the closed reduction and percutaneous crossed-pin fixation should always be taken into consideration. Exceptions are open fractures and those with multiple fragments.
