Cross-sectional Anatomy of the Ilium: Implications for Acetabular Component Placement in Total Hip Arthroplasty

John Antoniades MD, Vincent D. Pellegrini MD

High hip center reconstructions, used in revision and complex primary THAs, rely on pelvic bone stock at least 35 mm above the anatomic teardrop. However, the technique does not restore normal hip biomechanics and controversy exists regarding acetabular implant survival. Previous reports document a wide range of implant positioning above the teardrop. There is no anatomic guidance in the literature regarding the amount of bone stock available for initial implant stability in this area of the ilium.

Do Obesity and/or Stripe Wear Increase Ceramic Liner Fracture Risk? An XFEM Analysis

Jacob M. Elkins MS, Douglas R. Pedersen PhD, John J. Callaghan MD, Thomas D. Brown PhD

Hypothesized risk factors for fracture of ceramic liners include impingement, edge-loading, and cup malpositioning. These risk factors are similar to those for generation of stripe wear. However, it is unclear whether the biomechanical conditions contributing to stripe wear generation also increase the risk for ceramic liner fracture

Risk Factors for Dislocation After Revision Total Hip Arthroplasty

Nathan G. Wetters BS, Trevor G. Murray MD, Mario Moric MS, Scott M. Sporer MD, Wayne G. Paprosky MD, Craig J. Della Valle MD

Despite dislocation being the most frequent complication after revision THA, risk factors for its occurrence are not completely understood.

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.
