The effect of C-arm fluoroscope on unicompartmental knee replacement arthroplasty.

Purpose: The aim of this study was to identify the effectiveness of C-arm fluoroscope in unicompartmental knee replacement arthroplasty through the clinical and radiologic results.

Materials And Methods: We investigated the 33 cases of unicompartmental knee replacement arthroplasty in 31 patients who diagnosed degenerative arthritis of knee between February 2011 and March 2014. We divided 2 groups, one is 15 cases using C-arm fluoroscope during operation (group A), the other is 18 cases not using that (group B).

Influence of Early Bisphosphonate Administration for Fracture Healing in Patients with Osteoporotic Proximal Humerus Fractures.

Background: Bisphosphonates are generally known to adversely affect fracture healing because they inhibit osteoclastic bone resorption. However, some authors argue that bisphosphonates have no adverse effect on the restoration of the mechanical integrity of long bones after fractures. It is unclear whether bisphosphonates can be initiated safely in patients with acute proximal humerus fractures.
