Abstract

• The purpose of this study is extraction of acceptable angulation range of humeral supracondylar fracture in children. Forty five cases of humeral supracondylar fracture were examined for 5 years and 5 months from February, 1990 to June, 1995. For analysis of the result according to angulation of distal fracture fragment of the reduction of fracture site, we measured the valgus-varus angle and rotatory angle of distal fracture fragment. Forty five cases were classified into three groups for the evaluation of result. If the distal fragment has valgus angulation below 5 degrees or rotaion angulation below 5 degrees, classified as group I. valgus angulation above 5 degrees and below 10 degrees or varus angulation below 5 degrees or rotation angulation above 5 degrees below 10 degrees, classified as group II, varus angulation above 5 degees or rotation angulation above 10 degrees, classified as group III. For evaluation of result, we standardized the range of motion, the change of carrying angle, the deformity of elbow. We gave point to these items, thus, total point above 10 points was evaluated as excellent, 8~9 points as good, below 7 points as unsatisfactory, Group I showed good result in 21 cases among 22 cases, in Group II, good result to in 16 cases among 18 cases. In Group I and II, the good result is 95%, 38 cases among 40 cases. Thus, we concluded that the acceptable range in reduction of humeral supracondylar fracture in children is valgus angle below 10 degrees, varus angle below 5 degrees, rotation angle below 10 degrees.
