Epidemiological features of supracondylar fractures of the humerus in Chinese children.
We studied 450 children with a supracondylar fracture of the humerus in the period 1991 to 1995, and were able to collect full management details in 403 of them (253 boys and 150 girls). The median age at presentation was 6 years (6.6 years in boys, and 5 years in girls), with the nondominant humerus 1.5 times more commonly injured. Fifteen percent of children presented more than 1 day after the injury. Garland type III fractures constituted 45% of cases, type I 30%, and type II 24%, with flexion type fractures present only in 1% of the children. A nerve injury was associated with the fracture in 19 cases. Although the radial pulse was not palpable at presentation in nine patients, only one child had diminished distal circulation requiring exploration. Concomitant fractures were present in 14 patients. Elbow hyperextension was greater than in a comparable group of noninjured children. Open reduction was necessary in 20% of these children, most being managed by manipulation under anaesthesia, at times associated with percutaneous Kirschner wiring. The hospital stay was 2 days or less in two-thirds of the patients, with more than 90% discharged home within 1 week of admission. In conclusion, many Chinese patients attend hospital later than their Western counterparts, and the rate of flexion-type injuries is low.
