Breast implants improve quality of life in patients seeking improved breast aesthetics, and are known to minimize human injury in the less common scenario of penetrating trauma. People commonly sustain rib and sternum fractures and thoracic injury in motor vehicle crashes (MVC), a form of blunt traumatic injury. Whether breast implants minimize injury during MVC is unknown. This study examines the potential protective effect of breast implants in low speed, unrestrained MVC.
Control (medical gel) and implant (medical gel with embedded breast implant) blocks were subjected to load approximating a low speed, 10mph MVC (n=12 blocks per group). Colormetric pressure film measured pressure at the neo-chest wall position in response to load, across the gel block base. Maximum pressure and average pressure across the gel block base were compared, by group.
Presence of an implant significantly decreased, by 22.8%, maximum pressure experienced by the neo-chest wall (333.0 ± 58.7 psi vs 431.6 ± 37.3 psi, =0.0006). Average pressure experienced by the neo-chest wall across the gel block base was also significantly decreased, by 28.1%, in the implant group (53.4 ± 5.6 psi vs 74.3 ± 15.7 psi, =0.0017). Subjective analysis of all implant and control blocks supported an overall reduction in pressure for the implant group.
Presence of a breast implant decreased maximum pressure at the chest wall by 23%, and average pressure by 28%. Patients with breast implants involved in low speed, unrestrained MVC may be less likely to sustain rib and sternum fractures and thoracic injury, when compared to patients without implants.
乳房植入物可改善寻求改善乳房美观患者的生活质量，并且已知在较少见的穿透性创伤情况下可将人体损伤降至最低。在机动车碰撞（MVC）这种钝性创伤形式中，人们通常会发生肋骨和胸骨骨折以及胸部损伤。乳房植入物在MVC期间是否能将损伤降至最低尚不清楚。本研究探讨了乳房植入物在低速、未系安全带的MVC中的潜在保护作用。
将对照（医用凝胶）和植入物（嵌入乳房植入物的医用凝胶）模块施加近似低速、10英里/小时MVC的负荷（每组12个模块）。比色压力膜测量凝胶模块底部新胸壁位置对负荷的压力响应。按组比较凝胶模块底部的最大压力和平均压力。
植入物的存在使新胸壁承受的最大压力显著降低22.8%（333.0±58.7磅力/平方英寸对431.6±37.3磅力/平方英寸，P=0.0006）。植入物组新胸壁在凝胶模块底部承受的平均压力也显著降低28.1%（53.4±5.6磅力/平方英寸对74.3±15.7磅力/平方英寸，P=0.0017）。对所有植入物和对照模块的主观分析支持植入物组压力总体降低。
乳房植入物的存在使胸壁最大压力降低23%，平均压力降低28%。与未植入乳房植入物的患者相比，涉及低速、未系安全带MVC的乳房植入物患者发生肋骨和胸骨骨折以及胸部损伤的可能性可能较小。
