Cross-Linked Polyethylene for Total Hip Arthroplasty Markedly Reduces Revision Surgery at 16 Years
Total hip arthroplasty (THA) is an effective operation for the management of end-stage hip osteoarthritis, but long-term success can be limited by wear of the polyethylene bearing surface.

Inability of Older Adult Patients with Hip Fracture to Maintain Postoperative Weight-Bearing Restrictions
For elderly trauma patients, a basic goal is early mobilization, as immobilization can trigger various complications, such as venous thromboembolism, pneumonia, urinary tract infections, and pressure ulcers. https://bit.ly/2JIILyU #JBJSInfographics #JBJSVideoSummaries #VisualAbstract

Hip Arthroscopy: What and Who Account for Rising Utilization?
Hip arthroscopy for labral pathology and cam and pincer impingement has become increasingly established as an effective procedure in the hands of experienced surgeons. However, as with all technically complex orthopaedic procedures, success entails not only sound technique, but also appropriate patient selection, meticulous pre- and intraoperative setup, and appropriate use of intraoperative fluoroscopy. Thankfully, we have a community of leaders in arthroscopy who share and teach these details.
In the December 20, 2017 issue of The Journal, Duchman et al. use the ABOS Part-II exam database to analyze who among recent graduates of orthopaedic residencies is performing hip arthroscopies. Overall, between 2006 and 2015, the authors found that 643 of 6,987 ABOS candidates (9.2%) had performed ≥1 hip arthroscopy; nearly three-quarters of those reported sports-medicine fellowship training. More than two-thirds of candidates performing hip arthroscopy performed ≤5 such procedures; conversely, only 6.5% of those candidates performed 35% of all the hip arthroscopies identified in the database.
The concerning suggestion from these findings is that the increase in hip arthroscopy utilization comes from an increased number of individuals performing the surgery, rather than from an increase in procedure volume among individual surgeons. One question this study does not address is whether there has been an increase in the prevalence of hip pathology that warrants an increased utilization of this procedure. If not, an alternative explanation, which Wennberg et al. posit in the Dartmouth Atlas, is that procedure utilization expands in relationship to the distribution of provider resources and medical opinion in the local community.
I believe that hip arthroscopy is technically challenging and that the quality of the outcome is very likely related to the per-surgeon volume of procedures performed. This makes it incumbent upon all orthopaedists who offer this procedure to actively evaluate their outcomes with validated instruments so the practitioner and her/his patients can objectively understand and discuss what the results are likely to be.
In a commentary on this study, Rupesh Tarwala, MD calls for an outcomes analysis of patients who were treated with hip arthroscopy by ABOS Part-II candidates. I concur completely, and would more specifically ask that the cohort of surgeons evaluated in this study by Duchman et al. collect and report their 1- and 2-year outcomes to The Journal.

What’s New in Orthopaedic Trauma
Every month, JBJS publishes a Specialty Update—a review of the most pertinent and impactful studies published in the orthopaedic literature during the previous year in 13 subspecialties. Click here for a collection of all OrthoBuzz Specialty Update summaries.
This month, David Teague, MD, co-author of the July 5, 2017 Specialty Update on orthopaedic trauma, selected the five most clinically compelling findings from among the 34 studies summarized in the Specialty Update.
Tibial Fractures
A randomized, sham-controlled clinical trial1 failed to demonstrate improved functional recovery or accelerated radiographic healing with the addition of low-intensity pulsed ultrasound (LIPUS) to the postoperative regimen of fresh tibial fractures.
Postsurgical Weight-Bearing
Two studies support early weight-bearing (WB) after certain operatively managed lower extremity injuries, an allowance that may substantially improve a patient’s early independence. One randomized study2demonstrated that immediate WB after locked intramedullary fixation of tibial fractures is not inferior in union time, complication rates, or early function score when compared with a 6-week period of non-WB. The second randomized trial3 found early WB after select ankle fracture fixation (no syndesmosis or posterior malleolar fixation included) resulted in no increase in complications, fewer elective implant removals, and improved 6-week function, relative to late weight-bearing.
Pelvic Injuries
The addition of posterior fixation to anterior fixation for patients with anteroposterior compression type-2 injuries (symphysis disruption, unilateral anterior sacroiliac joint widening) improved radiographic results and led to fewer anterior plate failures.
Hip Fractures
Less femoral neck shortening occurred with cephalomedullary nail fixation devices (2 mm) than with a side plate and lag screw construct (1 cm) when treating OTA/AO 31-A2 intertrochanteric fractures (unstable, 3 or more parts) in patients ≥55 years of age, although functional outcomes were similar for the two groups.
