聚乙烯乙醇水化海藻盐泡沫材料覆盖负压封闭引流在髋臼骨折合并Morel-Lavallée损伤内固定前的应用

背景：髋臼骨折合并Morel-Lavallée损伤的报道较少，如何控制该损伤而早期进行骨折内固定治疗目前尚无公识的方法。 目的：进一步验证聚乙烯乙醇水化海藻盐泡沫材料覆盖负压封闭引流在髋臼骨折合并Morel-Lavallée损伤中的作用。 方法：选取23例髋臼骨折合并Morel-Lavallée损伤患者，随机分为2组，髋臼骨折内固定前实验组采用聚乙烯乙醇水化海藻盐泡沫负压封闭引流治疗Morel-Lavallée损伤，对照组采用清创治疗Morel-Lavallée损伤，比较两组患者伤后髋臼骨折实施手术的时间，采用改良Merle d’Aubigne和Postel评分系统对患者疗效进行评估。 结果与结论：实验组改良Merle d’Aubigne和Postel分值显著高于对照组(P < 0.05)。实验组和对照组髋臼骨折实施手术的时间分别为伤后(20.62±6.01) d和(28.00±8.07) d，两组差异有显著性意义(P < 0.05)。提示聚乙烯乙醇水化海藻盐泡沫负压封闭引流可加速Morel-Lavallée损伤的病灶愈合，为髋臼骨折早期手术提供必要条件，从而有助于髋臼骨折合并Morel-Lavallée损伤患者肢体功能恢复。

Application of vacuum sealing drainage dressing covered with polyethylene ethanol hydration seaweed salt foam in the Morel-Lavallée lesion complicated with acetabular fractures before internal fixation

BACKGROUND:Morel-Lavallée lesions complicated with acetabular fractures are rarely mentioned in literatures, at present how to control the lesion and early fracture fixation has no generally accepted method. OBJECTIVE:To further verify the effect of vacuum sealing drainage covered with polyethylene ethanol hydration seaweed salt foam in the Morel-Lavallée lesion complicated with acetabular fractures. METHODS:Twenty-three patients with Morel-Lavallée lesion complicated with acetabular fractures were divided into two groups. The patients in experimental group received vacuum sealing drainage intervention for the Morel-Lavallée lesion and those in control group received usual debridement before internal fixation of acetabular fractures. The times between the injury and the operation of acetabular fractures of two groups were compared. The clinical results were evaluated by the scores of Merle d’Aubigne and Postel. RESULTS AND CONCLUSION:The scores of Merle d’Aubigne and Postel in the experimental group were significantly higher than those in the control group (P < 0.05). The times between the injury and the operation of acetabular fractures in the experimental and control groups were (20.62±6.01) days and (28.00±8.07) days respectively, and the differences of the time between the two groups were significant (P < 0.05 ). The vacuum sealing drainage can promote the cure of the Morel-Lavallée lesion, then can made it possible for early operation of acetabular fractures, thus can improve the hip joint function for patients of the Morel-Lavallée lesion complicated with acetabular fractures after surgery.
