Abstract：
UNASSIGNED: Adequate reconstruction of the soft tissue defect following resection of bone tumors is challenging. Prolene mesh, despite being a useful tool, is not widely used due to the fear of deep infection. The aim of this study was to evaluate the functional outcome and complications of using a Prolene mesh in oncological reconstructions.
UNASSIGNED: A retrospective study was conducted in bone tumor patients with soft tissue reconstruction using Prolene mesh between January 2017 and June 2019. Functional evaluation was done using MSTS 93 score. Complications were recorded and were classified as mechanical (dislocation and extension lag) or biological failure (wound problems and deep infection). Comparison was performed between groups with and without biological failure to identify predictive variables.
UNASSIGNED: Of 116 patients, 68 were males and 48 were females, with median age of 22.5 years. Thirty nine patients had tumors of proximal tibia, 23 of proximal femur, 25 of proximal humerus, 24 of pelvis, and five tumors at other sites. Approximately two-thirds (62.9%) of our patients underwent endoprosthetic reconstruction while the rest underwent either biological or cement spacer reconstructions. Excellent or good functional outcomes were reported in 98.3% patients as per MSTS 93 scoring. Complications were noted in 22 patients (18.9%), of which 16 had biological failure, with four patients requiring debridement and mesh removal. Dislocation of prosthesis occurred in 2 patients of proximal femur replacement. Overall re-surgery rate was 5.1% (6 patients). There was no statistically significant difference between the groups with or without biological failure with respect to demographics, site of tumor, type of procedure, blood loss, duration of surgery and history of chemotherapy.
UNASSIGNED: Prolene mesh is a useful tool to reconstruct the soft tissue defects following bone tumor resections. It is readily available, reliable and provides reproducible results, with no added risk of wound complications.

摘要：
■骨肿瘤切除后软组织缺损的充分重建是具有挑战性的。Prolene网格,尽管是一个有用的工具，由于害怕深层感染而没有广泛使用。这项研究的目的是评估在肿瘤重建中使用Prolene网格的功能结果和并发症。
■在2017年1月至2019年6月期间，对使用Prolene网片进行软组织重建的骨肿瘤患者进行了回顾性研究。使用MSTS93评分进行功能评估。记录并发症，并将其分类为机械（脱位和延伸滞后）或生物故障（伤口问题和深部感染）。在有和没有生物学失败的组间进行比较，以确定预测变量。
■在116名患者中，68人是男性，48人是女性，平均年龄为22.5岁。39例患者有胫骨近端肿瘤，股骨近端23，肱骨近端25，骨盆24号，和其他部位的五个肿瘤。大约三分之二（62.9％）的患者接受了假体重建，而其余的患者接受了生物或水泥间隔物重建。根据MSTS93评分，98.3%的患者报告了优异或良好的功能结果。22例患者出现并发症（18.9%），其中16人有生物失败，四名患者需要清创术和网片切除。2例股骨近端置换患者发生假体脱位。总的再次手术率为5.1%(6例)。在人口统计学方面，有或没有生物衰竭的组之间没有统计学上的显着差异，肿瘤部位，程序类型,失血,手术时间和化疗史。
■Prolene网格是重建骨肿瘤切除后软组织缺损的有用工具。它是现成的，可靠并提供可重复的结果，没有增加伤口并发症的风险。
