It is known that an interesting and unusual axillary artery thrombosis may develop over a period of time if an improperly adjusted crutch impinges repeatedly on the axilla. A 39 year-old male developed occlusion of left axillary artery and gangrenes of the left fingers after he had used axillary crutch for 25 years because of limping of the left leg resulting from poliomyelitis. The left hand was salvaged by successful thrombectomy. We report this case, review and discuss the literatures.

The aim of this paper is to improve the design of a pair of axilla crutches through quality function deployment(QFD) and discomfort experiments. User needs for the crutches, as well as the engineering characteristics which have influence on the ergonomic quality of crutches were determined from the interview with many users. This information was entered in the house of quality, and the results show that the axillary pad and grip are the most important quality factors. And the results from the discomfort experiments confirmed the QFD output. A prototype reflecting the QFD results was proposed. The present study demonstrated how QFD approach can be a methodological tool geared to greater ergonomics consideration in product design.
