Reconstruction of the sternumdefect, regardless of the reason, should ensure the stability of the anterior chest wall, the return of acceptable respiratory parameters and the control of wounds. Stability of the chest wall can be provided by autogenous tissues or prosthetic materials. In our experience, the fibula free osteocutaneous flaps are harvested for reconstruction of the bone defect in two patients after full-thickness defect of the sternum and anterior chest wall.展开更多

Ideally, reconstruction should restore thumb length and position and retain thumb stability, mobility, and strength, while preserving sensation and aesthetics. Achieving these outcomes can be especially challenging in severe cases of soft tissue and bony loss. The authors present a case of a 20-year-old right-hand dominant female involved in a motor vehicle accident who sustained severe crush injuries and burns to her right hand. Her injuries included soft tissue and bony defects extending from the thumb to the distal radius, namely avulsion of the thumb and significant loss of the distal radial and carpal column, resulting in severe wrist instability. We employed a three-segment vascularized osteocutaneous fibula flap to reconstruct the thumb and wrist to restore bony construct, carpal support, and soft tissue coverage. Thumb motion could not be achieved, but this technique offered a sensate, functional post for opposition and the appearance of an anatomic hand. Because of this surgery, the patient was enabled to graduate from college and pursue full-time employment. The authors hope that this report will add to the fund of knowledge and surgeon armamentarium for similar devastating injuries demanding thumb and wrist reconstruction.展开更多
目的:综合分析游离组织瓣修复颌面部缺损后血管蒂异位骨化的发生率及其影响因素。方法:检索PubMed、Web of Science、中国知网数据库(CNKI),关键词为“pedicle ossification”“free flap”“maxillofacial”,检索时间为2000年1月1日至2...目的:综合分析游离组织瓣修复颌面部缺损后血管蒂异位骨化的发生率及其影响因素。方法:检索PubMed、Web of Science、中国知网数据库(CNKI),关键词为“pedicle ossification”“free flap”“maxillofacial”,检索时间为2000年1月1日至2021年12月1日的有关游离组织瓣血管蒂异位骨化的文献,采用RevMan 5.4软件进行meta分析。结果:纳入文献5篇,共计病例829例。影像学上可见的血管蒂异位骨化发生率约为11%;有临床症状的发生率约为2%。合并比值比显示,血管蒂异位骨化的发生与组织瓣类型有显著相关性(OR=14.01,95%CI=3.58~54.85,P<0.001),但其与性别(OR=1.63,95%CI=1.00~2.67,P=0.05)、重建部位(OR=0.90,95%CI=0.46~1.74,P>0.05)、是否做过放疗(OR=0.79,95%CI=0.52~1.22,P>0.05)无显著相关性。结论:游离组织瓣修复颌面部缺损后,影像学上可见的血管蒂异位骨化发生率约为11%,有临床症状的发生率约为2%。其发生主要与游离组织瓣的类型有关,多好发于游离腓骨瓣。展开更多
