Abstract: Background: Distal osteotomies of the first metatarsal are commonly used to correct hallux valgus deformities. Of the distal osteotomies, the Austin osteotomy is popular among foot surgeons on an international level. The precision of the osteotomy is important to achieve a congruous osteotomy. Objectives: The purpose of this study was to examine the effects of experience and technique on creating a precise Austin osteotomy. Method: Three individuals with varying levels of experience (student, resident and podiatric physician) created Austin osteotomies in metatarsal sawbones, using three different techniques (freehand, guide wire and osteotomy guide). The medial and lateral apical angles were measured, and the mean, standard deviation, and range of the angles were calculated. The differences between medial and lateral angles were also calculated. Results: The results indicated that the mean and range of the angles varied considerably with the freehand and guide wire techniques at all experience levels. The angles were accurate and consistent for all experience levels; however, when an osteotomy guide was used. The use of an osteotomy guide also noticeably reduced the number of divergent and convergent osteotomies. Conclusions: The use of an osteotomy guide consistently resulted in a more precise Austin osteotomy for all experience levels. [Copyright &y& Elsevier]
