The incidence of completely displaced overriding distal metaphyseal radial fractures in children is unknown, and the optimal treatment is controversial.

The COVID-19 pandemic has substantially impacted the delivery of health care, both through direct care associated with COVID-19 and through more pervasive effects. Our goal was to evaluate whether the number of orthopaedic consultations for firearm injuries differed during the early months of the COVID-19 pandemic compared with the same period in prior years. We hypothesized that the initial months of the COVID-19 pandemic, compared with the same period in prior years, would have a higher number of orthopaedic consultations for firearm injuries and a lower rate of outpatient follow-up after consultations.

Halter Traction for the Treatment of Atlantoaxial Rotatory Fixation
Yeung, Chi-Yung MD1,2,3; Feng, Chi-Kuang MD1,2,3,a
doi : 10.2106/JBJS.21.00831
February 2, 2022 - Volume 104 - Issue 3 - p 229-238
Atlantoaxial rotatory fixation (AARF) comprises a spectrum of abnormal rotational relationships between C1 (atlas) and C2 (axis). We aimed to evaluate the efficacy and long-term clinical outcomes of halter traction in treating patients diagnosed with primary AARF.
Redefining the 3D Topography of the Acetabular Safe Zone
Hevesi, Mario MD, PhD1,*; Wyles, Cody C. MD1,*; Rouzrokh, Pouria MD, MPH, MHPE1,2; Erickson, Bradley J. MD, PhD2; Maradit-Kremers, Hilal MD1; Lewallen, David G. MD1; Taunton, Michael J. MD1; Trousdale, Robert T. MD1; Berry, Daniel J. MD1,a

Dislocation is the most common reason for early revision following total hip arthroplasty (THA). More than 40 years ago, Lewinnek et al. proposed an acetabular “safe zone” to avoid dislocation. While novel at the time, their study was substantially limited according to modern standards. The purpose of this study was to determine optimal acetabular cup positioning during THA as well as the effect of surgical approach on the topography of the acetabular safe zone and the hazard of dislocation.
Is Discretionary Care Associated with Safety Among Medicare Beneficiaries Undergoing Spine Surgery?

Spine surgery and its corresponding costs have increased in recent years and are variable across geographic regions. Discretionary care is the component of spending variation that is independent of illness severity, age, and regional pricing. It is unknown whether greater discretionary care is associated with improved safety for patients undergoing spine surgery, as we would expect from value-based health care.
National Trends in Post-Acute Care Costs Following Total Hip Arthroplasty from 2010 through 2018
Serino, Joseph III MD1; Burnett, Robert A. III MD1; Della Valle, Craig J. MD1; Courtney, P. Maxwell MD2,a

Post-acute care remains a target for episode-of-care cost reduction following total hip arthroplasty (THA). The introduction of bundled payment models in the United States in 2013 aligned incentives among providers to reduce post-acute care resource utilization. Institution-level studies have shown increased rates of home discharge with substantial cost savings after adoption of bundled payment models; however, national data have yet to be reported. The purpose of this study was to evaluate national trends in post-acute care utilization and costs following primary THA over the last decade.
Development and Internal Validation of Machine Learning Algorithms for Predicting Hyponatremia After TJA
Kunze, Kyle N. MD1; Sculco, Peter K. MD1,a; Zhong, Haoyan MPA2,3; Memtsoudis, Stavros G. MD, PhD, MBA2,3,4,5; Ast, Michael P. MD1; Sculco, Thomas P. MD1; Jules-Elysee, Kethy M. MD2,4

February 2, 2022 - Volume 104 - Issue 3 - p 265-270
The development of hyponatremia after total joint arthroplasty (TJA) may lead to several adverse events and is associated with prolonged inpatient length of stay as well as increased hospital costs. The purpose of this study was to develop and internally validate machine learning algorithms for predicting hyponatremia after TJA.
A Systematic Review

Torsional hip deformities are common among patients undergoing hip arthroscopy. However, recent studies have suggested conflicting outcomes following arthroscopy in the setting of abnormal hip version. The purpose of this study was to systematically evaluate the literature and determine the impact of femoral and acetabular version on patient-reported outcomes following primary arthroscopic hip surgery.

The Multicenter Orthopaedic Outcomes Network (MOON) study of anterior cruciate ligament (ACL) reconstruction has achieved >80% follow-up for study subjects who were enrolled from 2002 to 2005; patient-reported outcome measures (PROMs) were reported at 2, 6, and 10 years through a carefully designed protocol that included surgeon involvement to encourage subjects to complete and return questionnaires. The process included emails and telephone calls from the central coordinating center, from research coordinators at each local institution, and lastly, from the subjects’ surgeons for those who were less inclined to complete the follow-up. In order to quantify the effect of site and surgeon involvement, the enrollment year of 2005 was monitored for the 10-year follow-up (n = 516 subjects). In contact efforts made by the coordinating center, 73.8% (381) of study subjects were reached by the central site coordinator, contact information was verified, and questionnaires were subsequently sent, completed, and returned. An additional 54 subjects (10.5% of the overall study population) returned the questionnaire after local study site involvement, indicating the importance of individual surgeon and local site involvement to improve follow-up rates in multicenter studies in orthopaedic surgery. Follow-up rates were higher when a specific individual (the surgeon or the research coordinator) was given the task of final follow-up.
