All patients who were placed into a CAM walker boot for >2 weeks were prospectively enrolled. Patients were placed by an orthopedic cast technician into either a tall or short CAM walker boot, based upon the appropriate boot type needed for treatment. Inclusion criteria included anticipated boot wear for at least two weeks, and weightbearing as tolerated weightbearing restrictions. Exclusion criteria included transitioning into a CAM walker boot as part of a postoperative protocol, injury requiring restricted weightbearing, or an additional acute injury to the lower back or lower extremity. Those who subsequently reported wearing the boot for less than two weeks or had a treatment plan change were removed from the study.

The primary outcome was the presence of secondary site pain that developed or worsened during CAM walker boot wear. Surveys inquired about the presence of secondary site pain, defined as lower back, ipsilateral hip, contralateral hip, ipsilateral knee, contralateral knee, contralateral ankle, and contralateral foot. Severity of pain was assessed using a 100-point visual analog scale (VAS), with zero indicating no pain and 100 representing the worst pain imaginable.

All patients who were placed into a CAM walker boot for >2 weeks were prospectively enrolled in the study. At the time of initiation of boot wear, patients were placed by an orthopedic cast technician into either a tall Aircast AirSelect Elite™ or short Aircast AirSelect™ CAM walker boot, based upon the diagnosis and appropriate boot type needed for treatment. Inclusion criteria included minimum age of 18 years, anticipated boot wear for at least two weeks, and weightbearing as tolerated weightbearing restrictions. Exclusion criteria included transitioning into a CAM walker boot as part of a postoperative protocol, injury requiring restricted weightbearing, or an additional acute injury to the lower back or lower extremity. Those who subsequently reported wearing the boot for less than two weeks were excluded. Additionally, patients who had a treatment plan change, such as proceeding with lower extremity surgery during the study period, were removed from the study.
