Licensed and Liable. Insurance, Road Regulations, and Driving After Hip and Knee Arthroplasty Surgery.

Background: There is a reliance on surgeons to provide advice to patients regarding safe return to driving following hip or knee arthroplasty. Concerns arise that misinformation may place the surgeon in a position of potential legal implication. The purpose of this article is to inform surgeons of their role in accordance with advice from insurance companies and transport regulatory bodies.

Risk Factors for Pathological Fracture and Metastatic Epidural Spinal Cord Compression in Patients With Spinal Metastases.

Vertebral pathological fracture and metastatic epidural spinal cord compression (MESCC) due to metastatic cancer inevitably cause pain, neurological deficit, impaired function, and decreased quality of life and are indications for surgery. In such cases, earlier surgical intervention has the potential to prevent permanent neurological deficit and disability and to maintain function and quality of life. Therefore, the aim of this study was to identify and evaluate risk factors for pathological fracture and MESCC in patients with spinal metastases.

Accuracy of Preoperative Scoring Systems for the Prognostication and Treatment of Patients with Spinal Metastases.

Background: In patients with spinal metastatic disease, survival prognosis is a key consideration in selection for surgery and determining the extent of treatment. Individual survival prediction however remains difficult. We sought to validate the prognostic accuracy of seven preoperative scoring systems.

Animal cancer models of skeletal metastasis.

The bony skeleton is one of the most common sites of metastatic spread of cancer and is a significant source of morbidity in cancer patients, causing pain and pathologic fracture, impaired ambulatory ability, and poorer quality of life. Animal cancer models of skeletal metastases are essential for better understanding of the molecular pathways behind metastatic spread and local growth and invasion of bone, to enable analysis of host-tumor cell interactions, identify barriers to the metastatic process, and to provide platforms to develop and test novel therapies prior to clinical application in human patients. Thus, the ideal model should be clinically relevant, reproducible and representative of the human condition.
