ARTICLE HIGHLIGHTS
Research background

Although the conventional cast has been effective in immobilizing orthopedic injuries, it has shortcomings such as foul odor, itchiness, internal moisture, inability to take a shower, etc. during its use. These could impede a patient’s compliance.

Research motivation

Opencast® is a recently developed mesh type of cast that allows ventilation and direct visual inspection of the skin. This cast is expected to avoid cast-related complications and discomfort. However, the advantage and efficacy of the cast have not been tested.

Research objectives

This study aimed to compare patients’ perspectives of the clinical benefits of the Opencast® and the conventional synthetic cast using a specifically designed questionnaire.

Research methods

Patients who sustained recent ankle sprain injuries were randomly allocated to group A (initial 2 wk of conventional cast + additional 2 wk of Opencast®) and group B (initial 2 wk of Opencast® and additional 2 wk of conventional cast). Patients’ perspectives on the complications and discomfort regarding the two types of cast were compared using a specifically designed questionnaire.

Research results

A total of 22 subjects participated in the study. The conventional cast appeared to be more rigid and stable than the Opencast®. Patient satisfaction tended to be rated higher after wearing the Opencast®. Opencast® was superior to the conventional cast in the items regarding itchiness, bad odor, ability to take a shower, etc.

Research conclusions

Opencast® was found to be appropriate for immobilization in patients with acute ankle sprains. Mechanical strength needs to be improved for this new type of cast.

Research perspectives

Opencast® could replace the conventional synthetic cast as it offers increased patient satisfaction, which would in turn increase compliance to treatment.
