소아 상완골 외과 골절 치료 후 운반각 변화 및 골극 형성

초록

Purpose; The purpose of this study is to evaluate the bony union, change of carrying angle and spur formation after treatment of lateral condyle fractures in children. Materials and methods: From march 1990 to september 1998, 30 cases of lateral condylar fractures treated with percutaneous pinning or open reduction and internal fixation and followed up more than 1 years were classified by the fracture type(Milch) and degrees of displacement(Jakob). We analysed the bony union, change of carrying angle and spur formation according to the classifications. Results: The mean union time was 7weeks. Average change of carrying angle was 2.1 degree(varus: 17, valgus: 9, no change: 4). Change of carrying angle was not related to the type of fracture and degree of displacement(p>0.05). Lateral spur formation was observed in 16 cases(Jakob I: 0, II: 6, III: 10 and Milch I: 2, II: 14). There was statistical significancy between the Jakob stage and lateral spur formation (p<0.05) but not between Milch type(p>0.05). Conclusion: The change of carrying angle was not affected by the fracture type and degree of displacement. Lateral spur formation was not affected by fracture type but related to the extent of displacement.
