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.

Is There a Risk in Placing a Ceramic Head on a Previously Implanted Trunion?

Didier Hannouche MD, PhD, Jérôme Delambre MD, Frédéric Zadegan MD, Laurent Sedel MD, Rémy Nizard MD, PhD

Strategies for revising a ceramic-on-ceramic total hip prosthesis are controversial. Some consider reimplantation of a ceramic head on a well-fixed femoral stem inadvisable as it may lead to a fracture of the newly implanted head.

Patient Perceived Outcomes After Primary Hip Arthroplasty: Does Gender Matter?

Carlos J. Lavernia MD, Jose C. Alcerro MD, Juan S. Contreras MD, Mark D. Rossi PhD

Total hip arthroplasty (THA) provides high functional scores and long-term survivorship. However, differences in function and disability between men and women before and after arthroplasty are not well understood.

A Prospective Randomized Trial of Mini-incision Posterior and Two-incision Total Hip Arthroplasty

Craig J. Della Valle MD, Emily Dittle RN, Mario Moric MS, Scott M. Sporer MD, Asokumar Buvanendran MD

The two-incision approach to THA has been controversial, with some authors reporting its use is associated with a rapid recovery whereas others report no differences in outcomes and a higher risk of perioperative complications secondary to increased surgical complexity.

Does Acetabular Retroversion Affect Range of Motion after Total Hip Arthroplasty?

Stephen J. Incavo MD, Jonathan E. Gold BS, Jesse James F. Exaltacion MD, Matthew T. Thompson MS, Philip C. Noble PhD

Increasingly, acetabular retroversion is recognized in patients undergoing hip arthroplasty. Although prosthetic component positioning is not determined solely by native acetabular anatomy, acetabular retroversion presents a dilemma for component positioning if the surgeon implants the device in the anatomic position.

What Works Best, a Cemented or Cementless Primary Total Hip Arthroplasty?: Minimum 17-year Followup of a Randomized Controlled Trial

Kristoff Corten MD, Robert B. Bourne MD, FRCS(C), Kory D. Charron Dipl.MET, Keegan Au MD, FRCS(C), Cecil H. Rorabeck MD, FRCS(C)

Total hip arthroplasty (THA) has been associated with high survival rates, but debate remains concerning the best fixation mode of THA.

Case Report: Bifid Iliopsoas Tendon Causing Refractory Internal Snapping Hip

Beatrice Shu MD, Marc R. Safran MD

Treatment of painful internal snapping hip (coxa saltans) via arthroscopic lengthening or release of the iliopsoas tendon is becoming preferred over open techniques because of the benefits of minimal dissection, the ability to address concomitant intraarticular disorders, and a low complication rate. Persistent snapping after release is uncommon, especially when performed arthroscopically. Reported causes include incomplete release, intraarticular disorders, and incorrect diagnosis. Anatomic variants are not discussed in the orthopaedic literature.

Reliability and Agreement of Measures Used in Radiographic Evaluation of the Adult Hip

Nicholas H. Mast MD, Franco Impellizzeri PhD, Stephan Keller MD, Michael Leunig MD

Several mechanical derangements reportedly contribute to the development of noninflammatory arthritis of the hip. Diagnosis of these derangements involves the use of specific radiographic measures (eg, alpha angle, lateral center edge angle, cross-over sign). The reliability of some of these measures is not known, whereas others have not been confirmed.

Do Ion Levels In Hip Resurfacing Differ From Metal-on-metal THA at Midterm?

A. Moroni MD, L. Savarino BSc, M. Hoque PhD, M. Cadossi MD, N. Baldini MD

Metal-on-metal Birmingham hip resurfacing (MOM-BHR) is an alternative to metal-on-metal total hip arthroplasty (MOM-THA), especially for young and/or active patients. However, wear resulting in increased serum ion levels is a concern.
