GCT which located at the lower end of the radius tends to be more aggressive. Wide excision and reconstruction of the wrist in stage 3 of distal radius GCT lesion is an optimal modality to prevent tumor recurrence. However, dislocation often occurs as its complication. We are reporting patient with GCT of distal radius treated with wide excision and reconstruction using nonvascularized fibular graft and the addition of hernia mesh. Circumferential non-absorbable polypropylene hernia mesh was applied, covered radioulnar joint and volar aspect of radius, and served as additional support to prevent dislocation. During five years and two months of follow-up, we found no dislocation in our patient. Furthermore, good functional outcome was obtained. Our finding suggests that the addition of hernia mesh after wide excision and reconstruction with nonvascularized fibular graft may benefit to prevent dislocation and provides an excellent functional outcome.展开更多

In 2008 and 2011, the United States Food and Drug Administration(FDA) issued Public Health Notifications ultimately informing providers and the public that complications associated with the use of synthetic mesh in the transvaginal repair of POP are not rare. In this review, we(1) examine literature characterizing surgical practice-patterns subsequent to the FDA announcements;(2) describe presentation of meshassociated complications and outcomes of management;(3) discuss the most recent materials science research; and(4) seek to characterize whether or not mesh has lived up to the long-term efficacy promise of a permanent implant. Durability of mesh-augmented anatomical outcomes do not consistently translate into improved patient satisfaction and subjective outcomes. This, when coupled with the possibility of mesh-associated complications, emphasizes the need for continued innovation beyond the status quo of current synthetic grafts.展开更多
目的建立人体下颈椎C3~7节段前路椎体次全切除钛网植骨融合术的三维有限元模型,分析术后椎体稳定性及内固定器械的应力分布。方法建立前路椎体C5节段次全切除钛网植骨钢板螺钉内固定颈椎C3~7节段有限元模型,同时建立C3~7节段下颈椎原始...目的建立人体下颈椎C3~7节段前路椎体次全切除钛网植骨融合术的三维有限元模型,分析术后椎体稳定性及内固定器械的应力分布。方法建立前路椎体C5节段次全切除钛网植骨钢板螺钉内固定颈椎C3~7节段有限元模型,同时建立C3~7节段下颈椎原始模型。对术后模型分别施加0.5、1.0、1.5、2.0 N·m扭矩,分析前屈、后伸、侧弯及轴向旋转时关节活动度(range of motion,ROM)、关节突关节最大应力与内固定器械整体应力分布情况。结果前路椎体次全切除减压融合术(cervical corpectomy and fusion,ACCF)后,C5重建节段ROM随扭矩的增大而增加,与无损模型在1.0 N·m、预载荷50 N工况下相比,C5重建节段、C3~4,C6~7和C3~7节段ROM分别下降81%、62%、58%和80%;C5重建节段后方关节突关节最大应力减小,临近节段关节突关节应力显著升高;钛网应力主要分布于运动受压侧,螺钉根部承受较大载荷。结论 ACCF术式会较大提升颈椎稳定性,降低手术节段后方关节突关节应力,对于减缓因脊髓型颈椎病引起的脊髓压迫有较好疗效。研究结果可为ACCF手术的临床应用研究提供理论依据。展开更多
