Background: Pain self-efficacy, or the ability to carry out desired activities in the presence of pain, can affect a patient's ability to function before and after orthopaedic surgery. Previous studies suggest that shared decision-making practices such as discussing patient-reported outcome measures (PROMs) can activate patients and improve their pain self-efficacy. However, the ability of PROMs to influence pain self-efficacy in patients who have undergone orthopaedic surgery has yet to be investigated.

The widespread availability of administrative claims data has unlocked opportunities to answer challenging clinical questions in hand surgery, overcoming the limitations of traditional data sets. Researchers are taking advantage of claims data sets to obtain samples from broader segments of the population and achieve statistical power that was previously unattainable. Therefore, a basic understanding of claims database research is quickly becoming an invaluable tool in the surgeon's toolkit, enabling the performance of ground-breaking research and the critical evaluation of data-driven results to inform clinical practice.

Article Synopsis
  • - The study tested a 3D printed dynamic external fixator (3DPDEF) against a traditional pins and rubbers traction system (PRTS) for treating unstable proximal interphalangeal (PIP) fracture-dislocations in cadaver fingers, aiming to see if one method was superior at maintaining joint stability.
  • - Ten cadaveric fingers were used to simulate PIP fracture-dislocations, and both fixators were assessed under 1,400 flexion-extension cycles using fluoroscopy to measure joint stability and displacement.
  • - Results showed that both fixators maintained stability effectively, with the 3DPDEF offering similar stability to PRTS while being easier to apply and less expensive, making it a viable option for

Background: Clinical practice guidelines (CPGs) are developed to guide physicians in providing consistent high-quality care. Despite availability of evidence-based guidelines for the treatment of distal radius fractures, prior work suggests many patients receive treatment that is misaligned with the CPG. We sought to explore barriers and facilitators of guideline-aligned care for distal radius fractures.

Purpose: Although metacarpal fractures are typically managed nonoperatively, when surgical management is indicated, metacarpal fractures are commonly treated with crossed Kirschner wires (K-wires), which may limit early range of motion. Intramedullary implants are increasing in use with the potential advantage of early range of motion; however, stability in oblique metacarpal neck fractures remains a theoretical concern. The purpose of this study was to determine the biomechanical stability of noncompressive intramedullary fixation for oblique metacarpal neck fractures compared with crossed K-wire fixation.

Article Synopsis
  • - The study aimed to examine the relationship between alignment of treatment goals between patients and physicians, patient satisfaction, and overall experience in hand and upper extremity surgery.
  • - Among 169 participants, it was found that 62% experienced goal concordant care; however, this alignment did not significantly impact patient satisfaction or experience.
  • - Notably, patients earning less than $50,000 showed higher chances of receiving goal discordant care, highlighting potential socioeconomic disparities in treatment outcomes that merit further investigation.

Article Synopsis
  • Patient-reported outcome measures (PROMs) are tools used in orthopaedic surgery to assess important aspects of musculoskeletal function, like pain and disability, but may fail to fully consider patients' specific functional demands.
  • A cross-sectional study involving 169 orthopaedic patients examined their demographics, function, functional demands, pain self-efficacy, and depression symptoms to understand these relationships better.
  • The study found that higher functional demands linked to better patient-reported physical function even after accounting for factors like pain self-efficacy and age, suggesting functional demands should be included in PROM assessments for more accurate results.

Background: Patient-reported outcome measures (PROMs) were originally developed as research tools; however, there is increasing interest in using PROMs to inform clinical care. Prior work has shown the benefits of implementing PROMs at the point of care, but a patient's health numeracy (their ability to understand and work with numbers) may affect their ability to interpret PROM results.

Materials And Methods: We recruited patients presenting to an outpatient orthopedic clinic.

Purpose: Underrepresentation and misrepresentation of historically underrepresented populations in randomized controlled trials (RCTs) may have implications for the validity of research results and their application for diverse populations. To evaluate the representation of historically linguistically, racially, and ethnically underrepresented participants in orthopaedic randomized controlled trials (RCTs) and to assess the use of translated and culturally adapted patient reported outcome measures (PROMs).

Methods: Separate and comprehensive literature searches of PubMed, Web of Science, and Embase databases were performed to identify RCTs utilizing PROMs between the years 2012 - 2022 among the top five highest 5-year impact factor orthopaedic journals according to the 2021 Journal Citation Reports database.

Background: In this study, we tested the null hypothesis that robotic-assisted total hip arthroplasty (THA) vs conventional THA was not associated with (1) the amount of postoperative opioid use and (2) the incidence of new, persistent opioid use.

Materials And Methods: We used a large, national administrative database to identify patients 50 years and older undergoing primary robotic or conventional THA. Patients with hip fractures or a history of malignancy, hip infection, or opioid use disorder were excluded.

Background: Patient-reported outcome measures quantify outcomes from patients' perspective with validated instruments. QuickDASH (Quick Disability of Arm, Shoulder and Hand, an upper extremity PROM) scores improve after completing instrument tasks, suggesting patient-reported outcome results can be modified. We hypothesized that performing lower extremity tasks on the knee injury and osteoarthritis outcome score for joint reconstruction (KOOS-JR) and hip disability and osteoarthritis outcome score for joint reconstruction (HOOS-JR) instruments would similarly improve the scores.

Purpose: The purpose of this study was to determine if adverse social determinants of health (SDOH) are associated with differential complication rates following surgical fixation of distal radius fractures and assess which SDOH domain (economic, educational, social, health care, or environmental) is most associated with postoperative complications.

Methods: Using a national administrative claims database, we conducted a retrospective cohort analysis of patients undergoing open treatment for an isolated distal radius fracture between 2010 and 2020. Patients were stratified based on the presence/absence of at least one SDOH code and propensity score matched to create two cohorts balanced by age, sex (male or female), insurance type, and comorbidities.

Background: While initial nonoperative management is the conventional approach for superficial triangular fibrocartilage complex (TFCC) tears, a substantial portion of these cases go on to require surgery, and the optimal duration of nonoperative treatment is unknown. In this study, we evaluate the cost-effectiveness of early versus late arthroscopic debridement for the treatment of superficial TFCC tears without distal radioulnar joint (DRUJ) instability.

Methods: We created a decision tree to compare the following strategies from a healthcare payer perspective: immediate arthroscopic debridement versus immobilization for 4 or 6 weeks with late debridement as needed.

Purpose: Clinical practice guidelines (CPGs) are recommendations developed for broad application to optimize high-quality care and decision-making. The composition of patients and outcome measures used in studies informing CPGs; however, has not been rigorously evaluated. With growing evidence that outcomes in musculoskeletal surgery vary by sociocultural factors, we aimed to: (1) review the linguistic, racial, and ethnic representation of the patients in the studies informing CPGs for distal radius fractures and (2) assess their use of linguistically and culturally adapted patient-reported outcome measures (PROMs).

Distal radius fractures are one of the most common upper extremity fractures across all age groups. Although the American Academy of Orthopaedic Surgery (AAOS) Clinical Practice Guidelines have defined recommendations for the treatment of distal radius fractures, the optimal time to surgery was not included. There remains relatively little guidance or consensus regarding the optimal timing of surgical intervention for distal radius fractures and the impact of time to surgery on outcomes.

Patient-reported outcome measures (PROMs) provide a standardized assessment from the patient about their own health status. Although originally developed as research tools, PROMs can be used in clinical care to complement objective functional measures (eg, range of motion) and are increasingly integrated to guide treatment decisions and predict outcomes. In some situations, when PROMs are used during clinical care they can improve patient mortality, outcomes, engagement, well-being, and patient-physician communication.
