Trends in the Incidence and In-Hospital Outcomes of Elective Major Orthopaedic Surgery in Patients Eighty Years of Age and Older in the United States from 2000 to 2009.
Although life expectancy continues to increase worldwide and advances occur in surgical techniques and medical treatment, the chronological age limit for patients to undergo elective major orthopaedic procedures remains a controversial subject. The purpose of this study was to examine the trends in the incidence and in-hospital outcomes of elective major orthopaedic surgery in patients eighty years of age and older in the United States as a whole. ⋯ Prognostic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Multicenter StudyOsteoarthritis Classification Scales: Interobserver Reliability and Arthroscopic Correlation.
Osteoarthritis of the knee is commonly diagnosed and monitored with radiography. However, the reliability of radiographic classification systems for osteoarthritis and the correlation of these classifications with the actual degree of confirmed degeneration of the articular cartilage of the tibiofemoral joint have not been adequately studied. ⋯ Diagnostic Level I. See Instructions for Authors for a complete description of levels of evidence.

Factors Affecting Readmission Rates Following Primary Total Hip Arthroplasty.
Readmissions following total hip arthroplasty are a focus given the forthcoming financial penalties that hospitals in the United States may incur starting in 2015. The purpose of this study was to identify both preoperative comorbidities and postoperative conditions that increase the risk of readmission following total hip arthroplasty. ⋯ Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Preoperative Radiographic and CT Findings Predicting Syndesmotic Injuries in Supination-External Rotation-Type Ankle Fractures.
The Lauge-Hansen classification system does not provide sufficient data related to syndesmotic injuries in supination-external rotation (SER)-type ankle fractures. The aim of the present study was to investigate factors helpful for the preoperative detection of syndesmotic injuries in SER-type ankle fractures using radiographs and computed tomography (CT). ⋯ Diagnostic Level II. See Instructions for Authors for a complete description of levels of evidence.

Anatomic Determinants of Sacral Dysmorphism and Implications for Safe Iliosacral Screw Placement.
Upper sacral segment dysplasia increases the risk of cortical perforation during iliosacral screw insertion. Dysmorphic sacra have narrow and angled upper osseous corridors. However, there is no validated definition of this anatomic variation. We hypothesized that pelves could be quantitatively grouped by anatomic measurements. ⋯ Sacral dysmorphism was found in 41% of the pelves. The major determinants of sacral dysmorphism are upper sacral segment coronal and axial angulation. The sacral dysmorphism score quantifies dysmorphism and can be used in preoperative planning of iliosacral screw placement.
