带血管蒂骨瓣转位在修复骨缺损中的应用

THE APPLICATION OF MIGRATING VASCULARIZED PEDICLE GRAFT OF BONE TO REPARING BONE DEFICIT (Report of 4 cases)

利用带血管蒂骨瓣局部移位移植,结合自体或同种异体骨移植,以修复因骨髓炎、骨囊肿及骨巨细胞瘤所致的骨缺损4例,使传统骨的“爬行替代”过程转化为一般骨折的愈合过程,缩短了愈合时间。随访证实疗效满意。应用本法无需借助于显微外科技术,无吻合血管并发症之虑,可直接观察良好的骨瓣血运,手术成功率高,骨愈合时间短,避免了长时间固定所带来的并发症。

The authors have applied local migration graft of vascu- larized pedicle bone combined with autografting or allograft of bone to reparing bone deficit of 4 cases during 1986 to 1988. The causes include osteomyelitis, bone cyst and giant cell tumor of bone. On the basis of retrospections of the treatment, the curative effect is satisfied. Migrating grafts of vascularized pedicle bone transforms the traditional repairing process of'Creeping replacement'into the healing process of common fracture. This method does not require microsurgical techniques, does not result in complications of anastomosis of the blood vessel, and makes the blood circulation of bone be observed directly. With shortened healing time of bone, it avoids the complications due to long time fixation and brings a high success rate but it is limited by anatomical region and distance of travel of blood vessel.
