Is L2 Paravertebral Block Comparable to Lumbar Plexus Block for Postoperative Analgesia After Total Hip Arthroplasty?

Richa Wardhan MD, Anne-Sophie M. Auroux PharmD, Bruce Ben-David MD, Jacques E. Chelly MD, PhD, MBA

Continuous lumbar plexus block (LPB) is a well-accepted technique for regional analgesia after THA. However, many patients experience considerable quadriceps motor weakness with this technique, thus impairing their ability to achieve their physical therapy goals.

What is the Prognosis of Revision Total Hip Arthroplasty in Patients 55 Years and Younger?

Muyibat A. Adelani MD, Karla Crook BS, Robert L. Barrack MD, William J. Maloney MD, John C. Clohisy MD

Revision THAs are expected to increase; however, few studies have characterized the prognosis of revision THAs in younger patients.

Modular versus Nonmodular Neck Femoral Implants in Primary Total Hip Arthroplasty: Which is Better?

Paul J. Duwelius MD, Bob Burkhart PA, Clay Carnahan PA, Grant Branam BSc, Laura Matsen Ko MD, YingXing Wu MD, Cecily Froemke MS, Lian Wang MS, Gary Grunkemeier PhD

Restoration of the hip center is considered important for a successful THA and requires achieving the right combination of offset, anteversion, and limb length. Modular femoral neck designs were introduced to make achieving this combination easier. No previous studies have compared these designs in primary THA, and there is increasing concern that modular designs may have a higher complication rate than their nonmodular counterparts.

Symptomatic Pulmonary Embolus After Joint Arthroplasty: Stratification of Risk Factors

Javad Parvizi MD, Ronald Huang MD, Ibrahim J. Raphael MD, William V. Arnold MD, PhD, Richard H. Rothman MD, PhD

Prophylaxis for pulmonary embolism (PE) after total joint arthroplasty (TJA) presents the clinical dilemma of balancing the risk of postoperative thrombotic risk and anticoagulation-related complications such as bleeding, hematoma formation, and infection. Risk stratification of patients undergoing TJA is needed to tailor prophylaxis based on thrombotic and bleeding risk.

Long-term Results and Bone Remodeling After THA With a Short, Metaphyseal-fitting Anatomic Cementless Stem

Young-Hoo Kim MD, Jang-Won Park MD, Jun-Shik Kim MD, Jun-Seok Kang MD

Long-term results of standard total hip arthroplasty (THA) in young patients were not optimal. There are a number of reported disadvantages to longer cementless stems in THA including thigh pain and proximal stress shielding. However, it is unknown whether a short, metaphyseal-fitting anatomic stem without diaphyseal fixation, which represents a possible alternative, will maintain fixation over the longer term.

Efficacy of Revision Surgery for the Dislocating Total Hip Arthroplasty: Report From a Large Community Registry

Tiare Salassa MD, Daniel Hoeffel MD, Susan Mehle BS, Penny Tatman MPH, Terence J. Gioe MD

Historically, achieving stability for the unstable total hip arthroplasty (THA) with revision surgery has been achieved inconsistently. Most of what we know about this topic comes from reports of high-volume surgeons’ results; the degree to which these results are achieved in the community is largely unknown, but insofar as most joint replacements are done by community surgeons, the issue is important.

Total Hip Arthroplasty Performed in Patients with Residual Poliomyelitis: Does it Work?

Byung-Ho Yoon MD, Young-Kyun Lee MD, Jeong Joon Yoo MD, PhD, Hee Joong Kim MD, Kyung-Hoi Koo MD

Patients with residual poliomyelitis can have advanced degenerative arthritis of the hip in the paralytic limb or the nonparalytic contralateral limb. Although THA is a treatment option for some of these patients, there are few studies regarding THA in this patient population.

High Complication Rate in Revision Total Hip Arthroplasty in Juvenile Idiopathic Arthritis

Stuart B. Goodman MD, PhD, Katherine Hwang MS, Susanna Imrie PT, MS

Revision total hip arthroplasty (THA) in patients with juvenile idiopathic arthritis (JIA) is challenging as a result of the patient’s young age, systemic disease, multiple affected joints, small proportions, and bone loss. The intermediate- to long-term results of these surgeries remain unknown.

Obesity Increases Length of Stay and Direct Medical Costs in Total Hip Arthroplasty

Hilal Maradit Kremers MD, MSc, Sue L. Visscher PhD, Walter K. Kremers PhD, James M. Naessens PhD, David G. Lewallen MD

The number of obese patients undergoing THA is increasing. Previous studies have shown that obesity is associated with an increased likelihood of complications after THA, but there is little information regarding the impact of obesity on medical resource use and direct medical costs in THA.

Cemented versus Uncemented Hemiarthroplasty for Displaced Femoral Neck Fractures: 5-year Followup of a Randomized Trial

Ellen Langslet MD, Frede Frihagen MD, PhD, Vidar Opland MD, Jan Erik Madsen MD, PhD, Lars Nordsletten MD, PhD, Wender Figved MD, PhD

Displaced femoral neck fractures usually are treated with hemiarthroplasty. However, the degree to which the design of the implant used (cemented or uncemented) affects the outcome is not known and may be therapeutically important.
