手指近节指骨骨折后旋转畸形的治疗

In situ osteotomy for correction of rotational deformity of the proximal pbAIAnx

目的探讨手指近节指骨骨折后原位截骨矫正旋转畸形的手术疗效。方法用钛板螺钉对6例手指近节指骨旋转畸形愈合的患者进行原位截骨矫形后固定，手术均采用背侧入路。结果术后随访6～22个月，伤口无感染及皮肤坏死，骨愈合时间为6—9周，无延迟愈合、骨不连或畸形愈合。结论近节指骨骨折处原位截骨不仅可提供更精确的矫形，恢复手指的功能，改善外观，还能解决骨折继发的肌腱粘连，最大限度地减少软组织的损伤。

Objective To investigate the effectiveness of in situ esteotomy for correction of rotational deformity of the proximal phalanx. Methods Six cases of proximal phalanx rotational defonnity resulted from fracture malunion were treated. Osteotomy was done at the site of the fracture via a dorsal approach. After correction of the rotation a contoured plate and screws were used for fixation. Results All patients were follow- up for 6 to 22 months. There was no infection or skin necrosis. Bone healing occurred in 6 to 9 weeks. There were no delayed union, nonunion or malunion. CondtllSiON In situ correction esteotomy can not only provide more accurate correction to restore finger function and appearance, but also addresses secondary tendon adhesion and decreases soft tissue damage.
