Lower extremity junctional injuries due to explosive blasts are among the most lethal sustained on the battlefield. To help reduce the effects of junctional and perineal trauma from this injury mechanism, a tiered Pelvic Protection System (PPS) was fielded during the war in Afghanistan.
Thirty-six patients with known PPS status who sustained traumatic above knee amputations, with and without perineal injuries, were identified from an operative amputation registry in Helmand Province, Afghanistan, spanning a 12-month period.
In Group 1 patients with above knee amputations who wore some tier of the PPS system, 47% (8 of 17) sustained junctional/perineal injuries. Of the patients in Group 2 who wore no PPS, 68% (13 of 19) sustained perineal injuries associated with proximal amputations. Overall, these differences were statistically significant (p = 0.0115).
Use of a PPS may reduce the risk of having severe perineal and lower extremity junctional injury in service members sustaining traumatic above knee amputations from an explosive blast.
下肢关节损伤是战场上最致命的爆炸伤之一。为了帮助减轻这种损伤机制造成的关节和会阴创伤的影响，在阿富汗战争期间引入了分层骨盆保护系统（PPS）。
从阿富汗赫尔曼德省的一个手术截肢登记处确定了 36 名已知 PPS 状态的患者，他们因创伤性膝上截肢，伴有或不伴有会阴损伤。
在第一组接受 PPS 系统部分层级保护的膝上截肢患者中，47%（17 名中的 8 名）发生了关节/会阴损伤。在第二组未佩戴 PPS 的患者中，68%（19 名中的 13 名）因近端截肢而发生会阴损伤。总体而言，这些差异具有统计学意义（p=0.0115）。
在因爆炸伤导致的创伤性膝上截肢的军人中，使用 PPS 可能会降低发生严重会阴和下肢关节损伤的风险。
