What Factors Affect Posterior Dislocation Distance in THA?

Jim Nevelos PhD, Aaron Johnson MD, Christopher Heffernan, James Macintyre, David C. Markel MD, Michael A. Mont MD

Dislocation remains common after total hip arthroplasty. Efforts have been made to identify and minimize risk factors. One such factor, jump distance, or the distance the femoral head must travel before dislocating, has been poorly characterized with respect to three-dimensional kinematics.

High Survival of Modular Tapered Stems for Proximal Femoral Bone Defects at 5 to 10 Years Followup

Andrew P. Houwelingen MD, Clive P. Duncan MD, MSc, Bassam A. Masri MD, Nelson V. Greidanus MD, MPH, Donald S. Garbuz MD, MHSc

Currently, the two most commonly used options for the revision of femoral components in North America are: cylindrical, nonmodular, cobalt-chromium stems and tapered, fluted, modular, titanium (TFMT) stems. Previous reports have cited high failure rates with cylindrical cobalt chrome stems in large femoral defects but the longer term survival of the fluted stems is unknown.

Early Experience With a Comprehensive Hip Preservation Service Intended to Improve Clinical Care, Education, and Academic Productivity

Christopher L. Peters MD, Stephen K. Aoki MD, Jill A. Erickson PA-C, Lucas A. Anderson MD, Andrew E. Anderson PhD

The field of hip preservation surgery has grown substantially over the past decade. Although open hip procedures reportedly relieve pain and restore function, arthroscopic treatment has increasingly become a reasonable alternative. In 2008, we formed a comprehensive hip preservation service (HPS) to address clinical, educational, and research needs.

The Withdrawn ASR™ THA and Hip Resurfacing Systems: How Have Our Patients Fared Over 1 to 6 Years?

Kevin T. Hug MD, Tyler S. Watters MD, Thomas P. Vail MD, Michael P. Bolognesi MD

The Articular Surface Replacement™ (ASR™) metal-on-metal hip arthroplasty system (DePuy Orthopaedics, Inc, Warsaw, IN, USA) reportedly has a higher than anticipated early failure rate leading to a voluntary recall. This prompted us to evaluate all ASR™ components implanted at our center.

Lessons Learned From Managing a Prospective, Private Practice Joint Replacement Registry: A 25-year Experience

Joshua T. Carothers MD, Richard E. White MD, Krishna R. Tripuraneni MD, Mohammad W. Hattab MS, Michael J. Archibeck MD

In 1984, we developed a private practice joint replacement registry (JRR) to prospectively follow patients undergoing THA and TKA to assess clinical and radiographic outcomes, complications, and implant survival. Little has been reported in the literature regarding management of this type of database, and it is unclear whether and how the information can be useful for addressing longer-term questions.

Alcohol Use in Elective Total Hip Arthroplasty: Risk or Benefit?

Carlos J. Lavernia MD, Jesus M. Villa MD, Juan S. Contreras MD

Excessive alcohol consumption has been associated with adverse health measures after elective surgery. The effects of low or moderate consumption remain unclear.

Reliability of Bucholz and Ogden Classification for Osteonecrosis Secondary to Developmental Dysplasia of the Hip

Andreas Roposch MD, MSc, FRCS, John H. Wedge OC, MD, FRCS(C), Georg Riedl MD

Osteonecrosis is perhaps the most important serious complication after treatment of developmental dysplasia of the hip (DDH). The classification by Bucholz and Ogden has been used most frequently for grading osteonecrosis in this context, but its reliability is not established and unreliability could affect the validity of studies reporting the outcome of treatment.

The 2012 Otto Aufranc Award: The Interpretation of Metal Ion Levels in Unilateral and Bilateral Hip Resurfacing

Catherine Straeten MD, George Grammatopoulos MD, Harinderjit S. Gill BEng, DPhil, Alessandro Calistri MD, Patricia Campbell PhD, Koen A. Smet MD

The interpretation of metal ion concentrations and their role in clinical management of patients with metal-on-metal implants is still controversial.

Disclosure of Financial Conflicts of Interest: An Evaluation of Orthopaedic Surgery Patients’ Understanding

Jay R. Lieberman MD, Michael J. Pensak MD, Michael S. Kelleher MD, Robin R. Leger PhD, Gregory G. Polkowski MD

Industry and orthopaedic surgeons often partner to develop new technology, which can lead to orthopaedic surgeons having financial conflicts of interest (FCOI). It is essential these FCOI be conveyed clearly to patients. It is unclear, however, whether and to what degree patients understand the ramifications of physician FCOI.

Anterior Delayed Gadolinium-enhanced MRI of Cartilage Values Predict Joint Failure After Periacetabular Osteotomy

Sang Do Kim MD, Rebecca Jessel MD, David Zurakowski PhD, Michael B. Millis MD, Young-Jo Kim MD, PhD

Several available compositional MRIs seem to detect early osteoarthritis before radiographic appearance. Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) has been most frequently used in clinical studies and reportedly predicts premature joint failure in patients undergoing Bernese periacetabular osteotomies (PAOs).
