RESUMO
Objective To compare the clinical effects on Gartland type Ⅲ fractures in children by open reduction and external fixation with two parallel Kirschner wires and closed reduction.Methods From February 2013 to October 2016,84 children with Gartland type Ⅲ supracondylar fracture of humerus were selected and randomly divided into a control group and an observation group,each with a total of 42 cases.The control group received closed reduction treatment,and the observation group received open and external fixation with two parallel Kirschner wires.The two groups were compared on intraoperative blood loss,incision length,operating time,decreased degrees of carrying angle,reduced flexion-extension at the fractured side and the rates for good and excellent clinical effects.Results The observation group behaved significantly better than the control group in intraoperative blood loss,incision length and operating time (P＜0.05).The rates for good and excellent effects was 90.47％ in the observation group and 73.81％ in the control group,and there was obvious difference between the values in the two groups (P＜0.05).The observation group had the decreased degree of carrying angle statistically lower than that in the control group (P＜0.05),while the reduced flexion-extension at the fractured side was not significantly different from that in the control group (P＞0.05).Conclusion Open reduction and external fixation with two parallel Kirschner wires and closed reduction both gain their advantages when used to treat Gartland type llⅢ fractures in children,the former has high clinical effect,significantly recovered elbow joint function and low incidence rate for cubitus varus,and the latter has slight invasion,small incision while relatively low clinical effect and high incidence rate for cubitus varus.

RESUMO
Supracondylar fracture of the humerus is the most common fracture of the elbow in children For period of 4 years from Jan. 1980 to Dec. 1983, 54 children with dispaced supracondylar fracture of the humerus were classified by direction of displacement of distal fragment and treated by immediate closed reduction after lateral skeletal traction. 32 cases of these were followed up for more than 6 months. The results were obtained as follows.: 1) The most common incidence (79.6%) was 5 to 12 years of age and male and female ratio was 2.4 : l. The left humerus was involved in 35 cases (64.8%). 2) Of all fracture, extension type was 96.3% and flexion type 3.7%. 3) Under the exact anteroposteier and lateral views, fractures were classified by displaced direction of distal fragment. Immediate closed reduction was done by using thick and strong periosteal hinge after lateral skeletal traction. The more accurate anatomical reduction was obtained by maintenance of reduction state and further correction during lateral skeletal traction, and complications such as VIC, loss of reduction were lessened probably. 4) For follow up study of 32 cases, final result were analized according to Mitchells classification. Excellent results were obtained 23 cases (71.9%) Good results were 8 cases (25.0%) Unsatisfactory result was 1 case (3.1 %) 5) In 2 cases of treatment failure, the brachialis muscle was buttonholed by metaphyseal spike of the proximal fragment. 6) During lateral skeletal traction, superficial infection was developed through pin tract in 4 cases. These were treated by the administration of antibiotics and there were no complication such as osteomyelitis.
