儿童肱骨外髁骨折X线—临床特征研究

目的 研究儿童肱骨外髁骨折的X线表现与预后的关系。方法 分析了21例儿童肱骨外髁骨折的X线片，右肘16例，左肘5例，11例行手术内固定，10例行石膏或夹板外固定术。结果 肱骨外髁干骺部薄骨片或三角形骨折块19例(90.5％)，伴肱骨小头碎裂2例；骨折块外移10例，骨折块外移伴旋转或翻转6例，骨折块无移位3例；肘关节肿胀无明显骨折线2例；肘部积液征(八字征)12例；外上髁骨骺提前骨化3例。结论 儿童肱骨外髁薄骨片或三角形骨折块是诊断肱骨外髁骨折的重要依据。

Clinical X-ray Diagnosis of Children Humeral Lateral Condyle Fracture

Objective To investigate the Radiological representations of children humeral lateral condyle fracture and their relationship to complications and prognosis. Methods X-ray films of 21 cases of children humeral lateral condyle fracture were retrospectively analyzed. There were 17 boys and 4 girls with a mean age of 6 years (2 to 9). Fractures were observed in right arms in 16 cases and left arms in 5 cases. 11 cases were treated with external gypsum or splint fixation, the other 10 cases were treated with operative internal fixation. Results Flimsy fragments or triangle pieces of metaphysis were presented at lateral humerus in 19 cases (90.5%), which accompanied with broken humerus capitulum in 2 cases; fragments displaced outwards were presented in 10 cases and accompanied with circumgyrated and retroflexion in 6 cases. No displacement of fragments was found in 3 cases. Elbow swelling without remarkable fracture-line were observed in 2 cases, sign of elbow joint dropsy were shown in 12 cases; Ossification of lateral epicondyle epiphysis in advance were found in 3 cases. Conclusions The radiological findings of flimsy fragments and triangle pieces are very important characteristics in diagnosis of children humeral lateral condyle fracture.
