Abstract
A prospective study was designed to evaluate the effect of a pneumatic intermittent impulse device in the treatment of postsurgical and posttraumatic swelling of the adult foot and ankle.
Two groups of patients and their respective controls were studied. Group A consisted of 19 patients and 19 controls with acute swelling of the foot and ankle after major elective or posttraumatic surgery. Group B comprised 18 patients and 16 controls with chronic postsurgical or posttraumatic swelling. The pneumatic intermittent impulse device was used according to a predetermined daily regimen in both the control and experimental groups. The control patients were treated identically, except that their impulse device was modified to prevent effective compression. Reduction in swelling was measured by volumetric analysis with water displacement at selected intervals for each group. When compared with their respective controls, those patients who used an active impulse device had a statistically significant reduction in swelling. We conclude that this device is effective in the control of both acute and chronic swelling after trauma and surgery of the foot and ankle.
