10、ical angulation of the neck in the anteroposterior (AP) plane of an average of 12.5 laterally and in the lateral plane of an average of 3.5 anteriorly.The proximal radial epiphysis is mainly supplied by periosteal blood vessels running from distal to proximal.,儿童桡骨颈骨折治疗,Anatomy By four years of age,

11、Mechanism,2 main mechanisms of injury were described in literature.In the more common type, a radial neck fracture occurs after a fall with the elbow in extension and valgus, resulting in a fracture with valgus angulation.In the rare type, the mechanism is a fall with the elbow flexed, which causes

12、temporary and posterior dislocation of the elbow joint.,儿童桡骨颈骨折治疗,Mechanism 2 main mechanisms o,Treatment,There is still some controversy about management of radial neck fractures in children. Acceptable degrees of angulation range from 15 to 45 degrees.We agree with the majority who recommend treat

13、ing fractures with an angulation of less than 30 degrees with immobilization alone and those with more than 30 degrees angulation by means of surgery.,儿童桡骨颈骨折治疗,Treatment There is still some,Reduction,The severely angulated fractures can be treated with closed reduction, percutaneous reduction, and

14、open Reduction.,儿童桡骨颈骨折治疗,Reduction The severely angula,Open reduction,open reduction is controversial.Traditionally, it was performed if closed manipulation failed.in general, outcomes after open reduction are worse than those obtained after closed reduction.after open reduction, the incidence of c

15、omplication , is higher than those after closed reduction.open reduction causes additional damage to the soft tissue, with fibrous adhesions and loss of range of motion.Some radial neck fractures are impossible to reduce with closed methods, requiring open reduction,儿童桡骨颈骨折治疗,Open reductionopen reduction,Advantage of ESIN,ESIN is a minimally invasive technique, allowing stable fixation, early mobilization, and anatomical reduction in most cases. The complication rate is low and good-to-excellent results can be expected.,儿童桡骨颈骨折治疗,Advantage of ESINESIN is a min,
