Neuronal Sprouting and Reorganization in Bone Tissue Infiltrated by Human Breast Cancer Cells.

Background: Pain is a common complication for patients with metastatic bone disease. Animal models suggest that the pain, in part, is driven by pathological sprouting and reorganization of the nerve fibers innervating the bone. Here, we investigate how these findings translate to humans.

Persistent wound drainage after tumor resection and endoprosthetic reconstruction of the proximal femur.

Purpose: To examine the prevalence of prolonged wound drainage (PWD) after tumor resection and endoprosthetic reconstruction of the hip.

Methods: Retrospective review of 86 consecutive patients with metastatic bone disease, malignant hematologic bone disease or bone sarcoma, treated with tumor resection and subsequent endoprosthetic reconstruction of the proximal femur, between 2010 and 2012, in a single center.

Results: PWD for 7 days or more was observed in 41 cases (48%).
