Stability before and after percutaneous anterior medullary fixation of lateral compression 1 and 2 pelvic ring disruptions: Should surgeons prioritize the anterior ring?

PURPOSE: Surgical intervention for lateral compression (LC) 1 and 2 pelvic ring fractures is controversial. Posterior ring stabilization remains the most common mode of initial fixation. However, greater mechanical instability is observed in the anterior component of LC pelvic fractures. This study tested whether reduction and percutaneous superior ramus fixation will decrease the instability of LC pelvic fractures on intraoperative fluoroscopic imaging. METHODS: All adult patients (≥ 18 years) presenting with either a Young-Burgess LC1 or LC2 pelvic ring disruption treated operatively with percutaneous anterior followed by posterior fixation by a single surgeon from July 2021 to June 2023 were retrospectively reviewed. Displacement of the anterior ring to intraoperative manual internal rotation stress examination under fluoroscopy was compared before and after anterior pelvic ring reduction and fixation and prior to posterior pelvic ring fixation. Pre- and post-operative visual analog scores (VAS) for pain were also compared. RESULTS: Twenty-one patients with a mean age of 48.7 years were included. Fifteen patients (71.4%) presented with an LC1, and six (28.6%) with an LC2 injury patterns. Anterior pelvic fixation alone provided 7.5mm reduction in mean displacement of the anterior pelvic ring (pre-operative = 9.2 mm vs. post-operative = 1.6 mm, p < 0.001). VAS significantly decreased from 7.2 one-day pre-operatively to 2.2 twenty-four h post-operatively (p < 0.001). CONCLUSIONS: Reduction and fixation of the anterior pelvic ring prior to posterior fixation for LC1 and LC2 pelvic ring disruptions substantially improves mechanical stability on intraoperative stress examination. Combination of percutaneous anterior and posterior fixation significantly decreased VAS above the MCID 24 h after stabilization.

Randomized controlled trials in the shoulder arthroplasty literature rarely include key demographic and socioeconomic patient data.

BACKGROUND: It is well known that socioeconomic and demographic variables can greatly affect health outcomes. Previous studies across medical and surgical subspecialties have demonstrated that these variables are frequently under-reported in randomized controlled trials (RCTs). No such study currently exists that examines rates of reporting of sociodemographic variables in shoulder arthroplasty RCTs. This study aims to present these rates and explore the impact of failing to report socioeconomic variables in shoulder arthroplasty RCTs. METHODS: The PubMed database was queried for the term shoulder arthroplasty. Sixty-five RCTs from the past 10 years were identified for inclusion from 5 high-impact orthopedic surgery journals. Each RCT was analyzed for patient age and sex or gender as well as the following sociodemographic variables: race, ethnicity, insurance status, income, work status, and education. It was also noted whether each of the above variable was mentioned in the results section of the article. Data were presented in a descriptive fashion as well as analyzed using χ2 and Fisher exact tests where appropriate. RESULTS: From 2014 to 2023, the 65 shoulder arthroplasty RCTs published reported age in 40 of 65 (61.5%) in their results sections and 61 of 65 (93.8%) in any section. Sex or gender was reported in 27 of 65 (41.5%) in their results sections and 61 of 65 (93.8%) in any section. No articles included any sociodemographic variables in the results section. Reporting rates for sociodemographic variables in any section were as follows: race, 6 of 65 (9.2%); ethnicity, 5 of 65 (7.7%); work status, 4 of 65 (6.2%); and insurance status, 1 of 65 (1.5%). No studies included income or education of the enrolled patients. There was no difference in reporting sociodemographic variables by journal (P = .45) or by year of publication (P = .57). However, no study prior to 2020 included any sociodemographic variable (0 of 27, 0%), whereas from 2020 onward 6 studies included at least 1 (6 of 38, 15.8%). Sociodemographic variables were reported significantly less frequently than age and sex or gender (P = .001). DISCUSSION: Our study found sociodemographic variables are rarely reported in shoulder arthroplasty RCTs, whereas age and sex or gender are reported with great frequency. In order to understand the results of shoulder arthroplasty RCTs, apply their findings to the care of our patients, and address health disparities, we must ensure these studies include patient sociodemographic data.

Demographic and Socioeconomic Patient Data Are Rarely Included in Randomized Controlled Trials for Femoral Acetabular Impingement and Hip Arthroscopy: A Systematic Review.

Purpose: To determine the rate of reporting for sociodemographic variables in randomized controlled trials (RCTs) investigating femoral acetabular impingement (FAI) and hip arthroscopy. Methods: PubMed, Scopus, and Web of Science were queried for articles relating to FAI and hip arthroscopy. Articles included in final analysis were RCTs investigating operative management of FAI. Included RCTs were analyzed for reporting of age and sex or gender as well as the following sociodemographic variables: race, ethnicity, insurance status, income, housing status, work status, and education level in the results section or any section of the paper. Data was analyzed using χ2 and Fisher exact tests with significance defined as P < .05. Results: Forty-eight RCTs were identified from 2011 to 2023. Age was reported in 48 of 48 (100%) of included papers; sex or gender was reported in 47 of 48 (97.9%). Reporting of sociodemographic variables in any section respectively was: race (7/48, 14.6%), ethnicity (4/48, 8.33%), insurance status (0/48, 0%), income (1/48, 2.08%), housing status (0/48, 0%), work status (3/48, 6.25%), and education (2/48, 4.17%). There was no significant difference for reporting demographic variables with respect to journal or year of publication (P = .666 and P = .761, respectively). Sociodemographic variables (9/48) were reported significantly less frequently than age and sex or gender (48/48) (P < .001). Conclusions: This study found that sociodemographic variables in FAI and hip arthroscopy RCTs are reported with much lower frequency than age and sex or gender. These findings may demonstrate the need to include patient sociodemographic data in RCTs so that their results can be better generalized and applied to the appropriate patient population. Level of Evidence: Level II, systematic review of level I and II evidence.

Rising incidence of acute total hip arthroplasty for primary and adjunctive treatment of acetabular fracture in older and middle-aged adults.

BACKGROUND: Acute total hip arthroplasty (THA) may be an alternative or an adjuvant to internal fixation for surgical treatment of acetabular fractures. We investigate recent trends in the operative management of acetabular fractures. We hypothesize that the incidence of acute THA for acetabular fractures has increased over time. METHODS: 4569 middle-aged (45-64 years) and older adults (≥ 65 years) who received acute operative management of an acetabular fracture within 3 weeks of admission between 2010 and 2020 were identified from the United States Nationwide Inpatient Sample database. Treatment was classified as open reduction internal fixation (ORIF), THA, or combined ORIF and THA (ORIF + THA). Patients were stratified by age ≥ 65 years old. Associations between demographic factors and the incidence of each procedure over the study period were modeled using linear regression. RESULTS: The relative incidence of treatments was 80.9% ORIF, 12.1% THA, and 7.0% ORIF + THA. Among patients aged 45-64 years old, THA increased 4.8% [R2 = 0.62; ß1 = 0.6% (95% Confidence Interval (CI) 0.2-0.9%)] and ORIF + THA increased 2.6% [R2 = 0.73; ß1 = 0.3% (95% CI 0.2-0.4%)], while the use of ORIF decreased 7.4% [R2 = 0.75; ß1 = -0.9% (95% CI -1.2 to -0.5%)]. Among patients ≥ 65 years old, THA increased 16.5% [R2 = 0.87; ß1 = 1.7% (95% CI 1.2-2.2%)] and ORIF + THA increased 5.0% [R2 = 0.38, ß1 = 0.6% (95% CI 0.0-1.3%)], while ORIF decreased 21.5% [R2 = 0.75; ß1 = -2.4% (95% CI -3.45 to -1.3%)]. CONCLUSION: The treatment of acetabular fractures with acute THA has increased in the last decade, particularly among older adults.
