Femoral Insufficiency Fractures Associated with Prolonged Bisphosphonate Therapy

Joseph D. Isaacs MD, Louis Shidiak MD, Ian A. Harris MD, PhD, Zoltan L. Szomor MD, PhD

Emerging evidence has linked the long-term use of bisphosphonates with femoral insufficiency fractures. It has been suggested that the prolonged effect on bone remodeling leads to the accumulation of microfractures and weakening of bone.

Comparison of Femoral Morphology and Bone Mineral Density between Femoral Neck Fractures and Trochanteric Fractures

Yuki Maeda MD, Nobuhiko Sugano MD, Masanobu Saito MD, Kazuo Yonenobu MD

Many studies that analyzed bone mineral density (BMD) and skeletal factors of hip fractures were based on uncalibrated radiographs or dual-energy xray absorptiometry (DXA).

Bisphosphonate Remains Highly Localized After Elution From Porous Implants

Kimberly McKenzie MEng, J. Dennis Bobyn PhD, Jacintha Roberts MEng, Dorota Karabasz BSc, Michael Tanzer MD

Local elution of zoledronic acid from a porous implant reportedly enhances periimplant bone formation and implant fixation. However, there is no information in the literature on the extent to which eluted bisphosphonate remains localized around the implant or becomes systemically distributed.

Hospital Economics of Primary THA Decreasing Reimbursement and Increasing Cost, 1990 to 2008

Adam J. Rana MD, Richard Iorio MD, William L. Healy MD

The introduction of new technology has increased the hospital cost of THA. Considering the impending epidemic of hip osteoarthritis in the United States, the projections of THA prevalence, and national cost-containment initiatives, we are concerned about the decreasing economic feasibility of hospitals providing THA.

Modular Femoral Sleeve and Stem Implant Provides Long-term Total Hip Survivorship

David Le MD, Karen Smith CRA, Dylan Tanzer, Michael Tanzer MD

A femoral implant with a modular sleeve and stem has been designed to allow independent and complete metaphyseal-diaphyseal fit and fill as well as independent rotation to accommodate anteversion at the time of THA.

Acetabular Component Positioning Using the Transverse Acetabular Ligament: Can You Find It and Does It Help?

Noah J. Epstein MD, Steven T. Woolson MD, Nicholas J. Giori MD

Several studies have reported that the transverse acetabular ligament (TAL) can be used to orient the acetabular component during total hip arthroplasty and that it can be identified in nearly all patients.

Quality of Life Following Proximal Femoral Replacement Using a Modular System in Revision THA

Muhyeddine M. Al-Taki MD, Bassam A. Masri MD, Clive P. Duncan MD, MSc, Donald S. Garbuz MD, MHSc

Proximal femoral replacement using a segmental modular system is one option for revision THA in the presence of severe bone loss or periprosthetic fracture. While many papers report function in these patients, they do not describe the quality of life.

The Frank Stinchfield Award: The Impact of Socioeconomic Factors on Outcome After THA: A Prospective, Randomized Study

R. Allen Butler MD, Seth Rosenzweig MD, Leann Myers PhD, Robert L. Barrack MD

Most studies of total hip arthroplasty (THA) focus on the effect of the type of implant on the clinical result. Relatively little data are available on the impact of the patient’s preoperative status and socioeconomic factors on the clinical results following THA.

The Incidence of Acetabular Osteolysis in Young Patients With Conventional versus Highly Crosslinked Polyethylene

Nathan A. Mall MD, Ryan M. Nunley MD, Jin Jun Zhu MD, PhD, William J. Maloney MD, Robert L. Barrack MD, John C. Clohisy MD

Osteolysis is a major mode of hip implant failure. Previous literature has focused on the amount of polyethylene wear comparing highly crosslinked polyethylene (HXPLE) with conventional liners but has not clarified the relative incidence of osteolysis with these two liners.
