The importance of osteoporosis in proximal humerus fractures is well recognized. However, the local distribution of bone quality in the humeral head may also have a significant effect because it remains unclear in what quality of bone screws of standard implants purchase. The goal of this study was to investigate whether the failure of proximal humerus locked plating can be predicted by the DensiProbe (ARI, Davos, Switzerland). ⋯ The validity of the DensiProbe was proven by the correlation between its peak torque measurements and BMD. The correlation between the peak torque and cycles to failure revealed the potential of the DensiProbe to predict the failure of locked plating in vitro. This method provides information about local bone quality, potentially making it suitable for intraoperative use by allowing the surgeon to take measures to improve stability.

Health care-related costs have been the focus of intense scrutiny in politics and in the media. However, public perception of physician reimbursement is poorly understood. The purpose of this study was to determine patient perception of physician reimbursement for 2 common hand surgery procedures: carpal tunnel release and open reduction and internal fixation of a distal radius fracture. ⋯ Higher level of education, annual household income, and insurance status had no statistically significant effect on patient estimates of reimbursement. Patients in an outpatient hand and upper extremity practice believe that surgeons are reimbursed at a rate 3.6 to 4.7 times greater than actual reimbursement. These misperceptions highlight the lack of understanding and transparency in health care costs and may interfere with the ability of patients to make well-informed decisions about health care.
