External fixation is frequently used to manage patients with lower extremity trauma. Excessive pressure from contact surfaces must be avoided to prevent added morbidity from heel ulcers. The purpose of this article is to present a simple solution to off-load the heel by adding a "kickstand" to the external fixator. The kickstand modification is designed to prevent breakdown of the soft tissue covering of the heel that can complicate the treatment of the initial injury and may also result in calcaneal osteomyelitis. By preventing such damage, the kickstand modification may also help to avoid radical procedures for soft tissue coverage, prolonged treatment times, and, ultimately, amputations. The kickstand device is made by adapting 2 extra rods and clamps to the primary external fixator to obtain proper clearance of the heel when the foot is resting over a surface. In cases where traditional off-loading devices are difficult to apply and can interfere with proper wound care, the kickstand might provide a useful preventive solution. From January to August 2006, we applied this technique in 10 patients with lower extremity trauma (11 fractures) and have seen no heel ulcers or other complications as per the staging system from the National Pressure Ulcer Advisory Panel.
外固定常用于治疗下肢创伤患者。必须避免接触表面产生过大压力,以防足跟溃疡增加发病率。本文旨在介绍一种简单的解决方法,即通过在外固定器上添加一个“支架”来减轻足跟压力。该支架改良设计旨在防止足跟软组织覆盖层受损,这种损伤会使初始损伤的治疗复杂化,还可能导致跟骨骨髓炎。通过防止此类损伤,支架改良还可能有助于避免进行软组织覆盖的根治性手术、延长治疗时间以及最终避免截肢。该支架装置是通过在主要外固定器上增加两根额外的杆和夹具制成的,以便在足部 resting over a surface 时使足跟获得适当的间隙。在传统减压装置难以应用且会干扰伤口正常护理的情况下,该支架可能提供一种有用的预防解决方案。2006年1月至8月,我们将此技术应用于10例下肢创伤患者(11处骨折),根据国家压疮咨询小组的分期系统,未发现足跟溃疡或其他并发症。
