The purpose of this study was to investigate the reported rates and characteristics of injuries among CrossFit athletes with specific attention to the hand and wrist. We further sought to identify trends and associations of these injuries by examining demographic data. A questionnaire was created to capture self-reported information on the incidence of hand or wrist injuries and their associations in CrossFit athletes. It was distributed between April 2020 and July 2020 to athletes training at CrossFit affiliated gyms in the New York and Pennsylvania regions. Bivariate logistic regression analysis was used to identify factors correlated with an injury. A total of 270 responses (97.5% response rate) were available for final analysis. The median age of respondents was 34 years and 72.2% had been participating in CrossFit for at least two years. CrossFit athletes reported injury rates of 62.2% while engaged in CrossFit training and 20.4% reported an injury specific to the hand or wrist. The majority of hand or wrist injuries occurred after one year of CrossFit training (65.4%). The majority of reported initial injuries occurred to the wrist (75.4%); subsequently, 29.1% reported reinjuring the same region. While 58.2% reported not yet having healed or taking longer than one month to feel fully healed, 72.8% reported returning to unmodified training within one month. Only 15 respondents reported seeking medical attention from a physician for their injury. Physicians generally recommended a training break of over one month, but only two patients reported taking a break this long. Male sex and length of participation in CrossFit were associated with an increased risk of developing a hand or wrist injury. Hand and wrist injuries represent a significant proportion of injuries among CrossFit athletes. CrossFit practitioners are potentially returning to unmodified training too early following injury, leaving them susceptible to further injury. Physicians and therapists must consider these findings and address both therapies and preventative measures for these types of injuries with their patients.

Periprosthetic joint infection (PJI) is a severe complication following total knee arthroplasty (TKA) and total hip arthroplasty (THA), associated with significantly increased patient morbidity and mortality. PJI remains the leading cause of early revision surgery after total joint arthroplasty and imposes a substantial financial burden on the healthcare system. In the United States, the incidence of PJI is estimated at 1–2% for primary THA and TKA procedures. Infections can arise from local spread from the skin or air, or through hematogenous seeding of the affected joint. Reducing the bacterial load at the surgical site is critical for preventing postoperative infections, and this goal is achieved through rigorous maintenance of perioperative sterility and appropriate antibiotic administration. Antibiotic prophylaxis is a cornerstone of infection prevention in arthroplasty and has been conclusively shown to lower the incidence of PJI. However, considerable variability and ongoing debate exist regarding the optimal route of antibiotic administration for infection prevention in THA and TKA. This review summarizes the current evidence on antibiotic strategies during primary total hip and knee arthroplasty, with the aim of informing perioperative management decisions among arthroplasty specialists and other clinicians involved in the care of these patients. This review will help guide perioperative decisions for arthroplasty specialists and will also serve as a valuable resource for general practitioners and infectious disease specialists who are involved in the care of patients who are about to undergo or have previously undergone a total joint arthroplasty procedure. This article is well-suited for publication in BMC Musculoskeletal Disorders because it addresses a major cause of morbidity and revision surgery in orthopaedic practice, aligning closely with the journal’s focus on musculoskeletal health and disease. By synthesizing current evidence on antibiotic prophylaxis in total joint arthroplasty, it offers practical guidance for clinicians, researchers, and policymakers seeking to improve surgical outcomes. The article’s multidisciplinary relevance, spanning orthopaedics, infectious disease, and perioperative care, fits the journal’s commitment to publishing research that bridges clinical practice and broader healthcare impacts.
