马德隆氏畸形的X线诊断探讨(附2例报告并文献复习)

Discussion and review on diagnosis of madelung deformity with X-ray in two cases

目的提高对马德隆氏畸形X线表现的认识。方法回顾性分析我院收治的2例和国内相关文献报道的16例马德隆氏畸形患者的临床资料和X线平片。结果18例中,男5例,女13例,年龄3-32岁,平均12.6岁,有家族史7例,双侧发病13例,占72%;合并骨软骨瘤4例。其X线表现为:①桡骨下端内侧1/3发育不良;②桡腕关节面角度变小;③月骨向桡侧半脱位;④尺骨下端向后脱位;⑤远侧尺桡关节间隙增宽。结论马德隆氏畸形具有典型x线表现,可为临床诊断、治疗提供详细、可靠的客观资料。

Objective To improve the understanding about the characteristic of X-ray findings in Madelung deformity. Methods The X-plain films and clinical data of 2 cases with Madehing deformity and 16 cases reported in Chinese biomedical literature were analyzed retrospectively. Results Among 18 cases with Madelung deformity, 5 men and 13 female, whose age are from 3 to 32 year old, with the average of 12.6. 7 cases of them had family history, 13 cases had bilateral lesions, account for 72% ; 4 cases merged osteochondroma. The X-ray characteristic signs of Madelung deformity were： 1. the medial 1/3 of the distal of radius was hypogenesis; 2. the angle of radiocarpal articular surface was wane; 3. the lunate bone was subluxation to the lateral of radius; 4. the lower extreme of ulna was backward dislocation; 5. the joint space of distal radioulnar was broaden. Conclusion Madelung deformity is of typical X-ray signs. X-ray plains could provide detailed, reliable, objective data for diagnosis and treatment.
