Accuracy of a Patient-Specific Total Ankle Arthroplasty Instrumentation.

Background: Total ankle arthroplasty (TAA) is a preferred surgical option for end-stage ankle osteoarthritis; however, it is a demanding procedure with a higher historical rate of revision compared with ankle fusion. Patient-specific instrumentation (PSI) has been introduced to optimize prosthesis alignment and theoretically overall improve TAA outcomes. The goal of this study is to report on the experience and surgical outcomes of one implant with specific evaluation of the accuracy and reproducibility of the system with respect to prosthesis alignment and prediction of implant size.

The World Health Organization Fracture Risk Assessment Tool (FRAX) underestimates incident and recurrent fractures in consecutive patients with fragility fractures.

Context: The World Health Organization Fracture Risk Assessment tool (FRAX) was developed to identify patients at risk of sustaining a fragility fracture (FF).

Objective: The objective of the study was to evaluate estimated FRAX probabilities of FF at the time of a FF and to compare them with the observed incidence of recurrent FF.

Methods: A prospective cohort included men and women older than 50 years at the time of a FF.

Atypical fracture of the tibial diaphysis associated with bisphosphonate therapy: a case report.

Atypical subtrochanteric femoral shaft fractures (AFFs) have recently emerged as a potential long-term complication of bisphosphonate therapy. In 2010, the American Society for Bone and Mineral Research (ASBMR) Task Force published a definition for AFF consisting of 5 major and 7 minor features. Little attention has so far been paid to the possibility that bisphosphonate-associated atypical fractures may also involve the diaphysis of other long bones.
