Swelling after ankle injury is more common in daily life. When an emergency patient is seen, if there is no obvious fracture, the doctor will usually advise the patient to rest in bed, elevate the patient, and take oral anti-swelling medications to improve the swelling of the limb. For patients with joint injuries requiring surgical treatment, ankle swelling is a very problematic matter. If the best time for emergency surgery is missed, most clinicians will wait until the swelling in the ankle has partially subsided before proceeding with surgery. This time can be long or short, and as it lengthens, fracture repositioning begins to become difficult. A recent article by Spengler et al. in JBJS describes the standard protocol for these three measures and provides a targeted comparison of their effectiveness in reducing swelling. It was found that the use of standard compression bandage could effectively reduce swelling after ankle injury and create favorable conditions for surgical preparation. Fifty patients with ankle sprains were randomly divided into three groups: ice and elevation of the affected limb; bandage compression group; and lower limb pneumatic pump treatment group. The figure-of-eight-20 method (Note 1) recommended by the authors was used to measure the degree of ankle swelling after these measures, and the groups were compared. After two days of treatment, the preoperative swelling was -2.0 mm, -11 mm, and -0.3 mm in the ice, bandage, and lower extremity pneumatic pump groups, respectively; after 2 days of treatment with the above methods, the mean edema reduction in the affected limb was +3.5 mm, -7.5 mm, and -7.5 mm in the ice, bandage, and lower extremity pneumatic pump groups, respectively. 3.5 mm, -7.3 mm, and +5.0 mm, respectively. The authors of the original article concluded that compression bandaging of the lower extremity was more effective and faster in reducing swelling in the ankle joint, and could be the preferred clinical measure. In contrast, lower extremity pneumatic pumps used to treat swelling after ankle injury are not as clinically effective as common ice measures. Given its high cost, it is not recommended as a routine measure in the clinic. Our suggestion: lower limb compression with elastic bandage may have some hidden risks, such as skin pressure injury, blood circulation disorders, etc. The relevant measures must be carried out under the guidance of a specialist, and should not be implemented blindly by oneself.
