Mora S, Zalavras CG, Wang L, Thordarson DB. The role of pulsatile cold compression in edema resolution following ankle fractures: a randomized clinical trial. Foot Ankle Int. 2002 Nov;23(11):999-1002.
Design: Randomized controlled clinical trial
Subjects: 24 patients with displaced ankle fractures awaiting surgery.
Methods: Patients were randomized into a study (n=11) or a control group (n=13). • In the study group patients had a Aircast Cryo/Cuff device applied to their ankle and remained at bed rest with the extremity elevated while awaiting surgery. • In the control group patients remained in a posterior molded splint instead of the PCC device. Outcomes included: Baseline circumferential measurements of the ankle, 24- hour increments to evaluate edema resolution, patient satisfaction.
Key message: The Cryo/Cuff was well tolerated and resulted in a significantly greater reduction of ankle circumference compared to splinting and elevation alone. The addition of compression augments the effectiveness of cryotherapy by increasing the extracellular hydrostatic pressure, thus decreasing edema formation.
Results:
• The Cryo/Cuff resulted in a significantly greater reduction of ankle circumference compared to splinting and elevation alone at 24h (2.9% vs. 0.6%), 48h (4.4% vs. 1.7%), and 72h (4.9% vs. 1.6%) after its application. • The Cryo/Cuff was well tolerated : patients were all satisfied or very satisfied with the device (median score = 4).
