Abstract：Objective To explore the application of the artificial mesh in reconstruction of the joint capsuleand soft tissue in the case of malignant bone tumor treated with wide resection and prosthesis replacement.Methods From Jun 2012 to Apr 2017,21 cases of malignant tumor near shoulder,hip and knee joint were treated by reconstruction surgery with prosthesis replacement.The surgical procedure was regional wide resection and prosthesis replacement with joint capsule reconstructed by artificial mesh.All cases were followed up after operation.The clinical results were evaluated post-operatively.Results There were 12 males and 9 females,age from 14 to 78 years.There were 3 tumorsin acetabulum,4 in proximal humerus,11 in proximal femur and 3 in proximal tibia.5 of themwere secondary lesions and 16 were primary malignant bone tumors.All patients were followed up for 32 months,ranging from 9 to 54 months with well-healed incisions.The drainage of less than 50ml/24h was the indication to pull out the drainage tube.No infection or dislocation occurred.At the last follow up,all patients were satisfied with the results of surgery.Conclusion The artificial mesh plays an important role in increasing the stability of joints after prosthesis replacementand improving the function of reconstructed soft tissues after wide resection.Satisfactory results has been obtained.
