Strategies of enhancing bone regenerate formation in distraction osteogenesis.

Distraction osteogenesis (DO) is a commonly used technique in multiple orthopedic sub-specialties, including trauma, oncology and pediatrics. This technique aims to produce new bone formation in the distraction gap in a controlled manner. The issue with this technique has been the high risk of complications, one of which is poor regenerate formation during the distraction process.

Primary Total Hip Arthroplasty: Equivalent Outcomes in Low and High Functioning Patients.

Objective: Previous studies suggest that patients with poorer physical function prior to undergoing total hip arthroplasty (THA) have a lower postoperative functional outcome. We sought to determine if the preoperative level of function was predictive of the outcome in patients undergoing THA using modern perioperative protocols and surgical techniques.

Methods: A prospective cohort study design evaluated the preoperative and 2-year postoperative health-related quality of life (HRQoL) scores of 200 patients who underwent THA.
