Limited Intraobserver and Interobserver Reliability for the Common Measures of Hip Joint Congruency Used in Dysplasia

A. Noelle Larson MD, Brien Rabenhorst MD, Adriana Rocha BS, MS, Daniel J. Sucato MD, MS

A congruent hip frequently is cited in the literature as a prerequisite for performing a reconstructive pelvic osteotomy for hip dysplasia. The designation as congruent is important as incongruent joints generally are regarded as requiring a salvage-type procedure. Several measures of congruency are described in the literature, but it is unclear whether these measures are reliable.

Periprosthetic Bone Remodeling after 12 Years Differs in Cemented and Uncemented Hip Arthroplasties

Prakash Chandran MS, FRCS (Ortho), Mohammed Azzabi MRCS, Mark Andrews FRCS (Ortho), John G. Bradley FRCS

Different patterns of stress shielding may lead to differences in periprosthetic bone preservation around cemented and uncemented hips in the long term?

2011 Marshall Urist Young Investigator Award: When to Release Patients to High-impact Activities after Hip Resurfacing

Katherine M. Bedigrew MD, Erin L. Ruh MS, Qin Zhang MD, MPE, John C. Clohisy MD, Robert L. Barrack MD, Ryan M. Nunley MD

Surface replacement arthroplasties are commonly performed in young, active patients who desire return to high-impact activities including heavy manual labor and recreational sports. Femoral neck fracture is an arthroplasty-related complication unique to surface replacement arthroplasty. However, it is unclear regarding whether patients are at lower risk for fracture after a certain postoperative time.

Pelvic Discontinuity Treated With Custom Triflange Component: A Reliable Option

Michael J. Taunton MD, Thomas K. Fehring MD, Paul Edwards MD, Thomas Bernasek MD, Ginger E. Holt MD, Michael J. Christie MD

Pelvic discontinuity is an increasingly common complication of THA. Treatments of this complex situation are varied, including cup-cage constructs, acetabular allografts with plating, pelvic distraction technique, and custom triflange acetabular components. It is unclear whether any of these offer substantial advantages.

Does Age or Bilateral Disease Influence the Value of Hip Arthroplasty?

Bryan M. Lawless MD, Meridith Greene BA, James Slover MD, MS, Young-Min Kwon MD, PhD, Henrik Malchau MD, PhD

Measuring value in medicine is an increasingly important issue as healthcare spending continues to rise and cost containment becomes even more important. However, value assessments can be affected by patient factors and comorbidities.

Does Ipsilateral Knee Pain Improve after Hip Arthroplasty?

Wenbao Wang MD, Jeffrey A. Geller MD, Jonathan D. Nyce BS, Jung Keun Choi MD, William Macaulay MD

Intraarticular hip disease is commonly acknowledged as a cause of ipsilateral knee pain. However, this is based primarily on observational rather than high-quality evidence-based studies, and it is unclear whether ipsilateral knee pain improves when hip disease has been treated.

Surgical Technique: A Simple Soft-tissue-only Repair of the Capsule and External Rotators in Posterior-approach THA

James A. Browne MD, Mark W. Pagnano MD

Posterior soft tissue repair after posterior THA reportedly decreases the risk of dislocation. Previously described techniques often require drill holes through the greater trochanter, do not include both the short external rotators and the capsule, or require a complex series of multiple sutures. We therefore describe a technique to address these issues.

Incidence of Contralateral THA After Index THA for Osteoarthritis

Siraj A. Sayeed MD, Aaron J. Johnson MD, David E. Jaffe MD, Michael A. Mont MD

Currently more than 200,000 THAs are performed annually in the United States. In patients with bilateral disease, the chance of subsequent contralateral THA reportedly ranges from 16% to 85%. Factors influencing contralateral THA are not completely understood.

Overdiagnosis of Pulmonary Embolism: Evaluation of a Hypoxia Algorithm Designed to Avoid This Catastrophic Problem

Brian S. Winters MD, Mark Solarz MD, Christina L. Jacovides BS, James J. Purtill MD, Richard H. Rothman MD, PhD, Javad Parvizi MD, FRCS

We observed a substantial increase in the incidence of pulmonary embolism (PE) after total joint arthroplasty (TJA) when multidetector computerized tomography (MDCT) replaced ventilation-perfusion (V/Q) scans as the diagnostic modality of choice. We questioned whether this resulted from the detection of clinically unimportant PE with the more sensitive MDCT and in 2007 instituted a hypoxia protocol to enhance the detection of PE.

Can a Periarticular Levobupivacaine Injection Reduce Postoperative Opiate Consumption During Primary Hip Arthroplasty?

Terence P. Murphy MCh, Damien P. Byrne PhD, Paul Curtin MCh, Joseph F. Baker MCh, Kevin J. Mulhall FRCS (Tr and Orth)

Several reports have confirmed the ability of intraoperative periarticular injections to control pain after THA. However, these studies used differing combinations of analgesic agents and the contribution of each, including the local anesthetic agent, is uncertain. Understanding the independent effects of the various agents could assist in improved pain management after surgery.
