Background  Breast trauma is an often under-recognized injury, especially in female polytrauma patients. The purpose of this study was to assess the prevalence of breast injuries and their association with injury severity score (ISS) in trauma patients nationally.  Method A retrospective review was performed using data from the National Trauma Data Bank® (NTDB®) from 2016 to 2019, using all applicable International Classification of Diseases (ICD) codes for three outlined subgroups (abrasions, contusions, and open wounds/punctures/lacerations) with minors excluded. All continuous variables were tested as non-normally distributed, and all test results for continuous variables used the Kruskal-Wallis test. All categorical variables were tested using a chi-squared test. Results  Patients with traumatic breast abrasions and contusions had a higher rate of intensive care unit (ICU) admissions (23.8%; n=395 and 25.3%; n=48, respectively) compared to patients with open wounds/punctures/lacerations (13.6%; n=205). Patients with abrasions and contusions to the breast had a significantly higher ISS compared to those with visible open wounds/punctures/lacerations (9 and 9, vs 5, p <0.001). Mortality rates were highest among patients with breast abrasions and contusions, 15% (n=213) and 14% (n=23), respectively, compared to patients with open wounds/punctures/lacerations at 11% (n=132), p<0.017. Conclusion  Traumatic breast abrasions and contusions were associated with higher rates of ICU admission, elevated ISS, and overall mortality compared to open breast wounds, punctures, or lacerations. This indicates the importance of traumatic breast injuries as a prognostic indicator in the standard workup of a trauma patient.

Breast injury is commonly encountered yet it remains significantly underreported. Injury to the breast may arise from either primary mechanisms or secondary or iatrogenic mechanisms. Primary mechanisms of breast injury include blunt force, seat-belt, penetrating, and thermal injury. Secondary or iatrogenic mechanisms of breast injury include breast biopsy or intervention as well as operative intervention and cardiopulmonary resuscitation. The severity of breast injury arising from these mechanisms is broad, ranging from breast contusion to avulsion. Sequelae of breast injury include fat necrosis and Mondor\'s disease. Radiologists play an integral role in the evaluation and management of breast injury both in the acute and non-acute settings. In the acute setting, radiologists must be able to recognize breast injury arising from primary mechanisms or iatrogenic or secondary mechanisms and to identify rare but potentially life-threatening complications promptly to ensure timely, appropriate management. In the non-acute setting, radiologists must be able to discern the sequalae of breast injury from other processes to prevent potentially unnecessary further evaluation and intervention. Nonetheless, though breast injury is commonly encountered there remain few guidelines and a lack of established recommendations for the evaluation and management of breast injury. We provide a comprehensive multi-modality imaging review of breast injury arising in the acute setting as well as the sequela of breast injury arising in the non-acute setting. Moreover, we provide an overview of the management of breast injury.

OBJECTIVE: In 2015-2016, over 214,000 female athletes competed at the collegiate level in the United States (U.S.). The National Collegiate Athletic Association (NCAA) collects injury data; however, breast-related injuries do not have a specific reporting category. The exact sequelae of breast injury are unknown; however, a relationship between breast injury and fat necrosis, which mimics breast carcinoma, is documented outside of sports participation. Breast injuries related to motor vehicle collisions, seatbelt trauma, and blunt trauma have been reported. For these reasons, it is important to investigate female breast injuries in collegiate sports. The objectives of this study are to report the prevalence of self-reported breast injuries in female collegiate athletes, explore injury types and treatments, and investigate breast injury reporting and impact on sports participation.
METHODS: A cross-sectional study of female collegiate athletes at four U.S. universities participating in basketball, soccer, softball, or volleyball. Main outcome measure was a questionnaire regarding breast injuries during sports participation.
RESULTS: Almost half of the 194 participants (47.9%) reported a breast injury during their collegiate career, less than 10% reported their injury to health personnel with 2.1% receiving treatment. Breast injuries reported by breast injuries reported by sport include softball (59.5%), basketball (48.8%), soccer (46.7%), and volleyball (34.6%).
CONCLUSIONS: The long-term effects and sequelae of breast injuries reported by female collegiate athletes during sport play are unknown. Nearly 50% of participants had a breast injury during sports activities. Although 18.2% indicated that breast injury affected sports participation, only 9.6% of the injuries were reported to medical personnel with 2.1% receiving treatment.

BACKGROUND: Legislation, education and technology have led to a rise in the use of seat belts. This has significantly reduced automobile accident-related mortality, but it has increased seat belt-associated injuries. The aim of this study was to review all publications on seat-belt injury to the female breast and to analyse patterns of presentation, management and outcomes.
METHODS: A literature search was performed by two independent reviewers using the PubMed, Scopus and EMBASE databases. The MeSH terms included \'seat belt breast\' or \'breast traffic accident\' or \'safety belt breast\'. This study was supported by Level V evidence.
RESULTS: In this review, 26 articles describing 42 patients were included. A total of 13 patients (31.0%) presented immediately after the road traffic accident (RTA) with pain, swelling, open wounds and/or haemorrhage of the breast. Active arterial extravasations were treated with angiographic embolization while wounds were mostly treated with dressings. Twenty-nine (69.0%) patients presented late, with a mean time of 6.77 months (3 weeks-5 years) after the RTA. This ranged from a palpable lump in the area of trauma to a worsening cleft deformity. Most late presentations were diagnosed with fat necrosis while five patients (17.2%) were found to have breast cancer. From this review, we propose a four-tier classification system that categorizes patients based on timing to presentation and symptoms, with recommended investigation and management options for each category.
CONCLUSIONS: This is the most comprehensive systemic review to date of seat-belt injuries to the female breast, and our proposed classification may be useful in the management of such patients.
