Original ResearchAverage Depth of Tarsometatarsal Joint for Trephine Arthrodesis
Section snippets
Materials and Methods
A total of 51 fresh-frozen, cadaveric limbs were used in the present investigation after institution review board approval. The cadaveric specimens were procured from Biogift Anatomical Inc. (Portland, OR). The available data were obtained from the individual specimens, including age, gender, laterality, and shoe size. The data were collected from August 2010 through October 2010. The foot length was first measured in millimeters, and a Brannock device was then used to record the U.S. shoe size.
Results
The mean foot length for the 51 limbs was 24.5 cm (U.S. men’s size 6 and women’s size 7.5). The mean joint depth for the first through third MC joint was 32.3, 26.9, and 23.6 mm, respectively (Table 1). The mean age of these subjects was 74.5 years. Of the 51 limbs, 28 were right limbs and 23 were left limbs. The frequency of each foot length and joint depth were also recorded (Table 2). Some limbs did not include all demographic data, including age and gender; therefore, statistical analysis
Discussion
The data collected from the present trial showed the average joint depth for the first through third MC joints and average plantar cortex depth (Table 7). These results should assist surgeons when performing Lisfranc trephine fusion procedures.
Additionally, statistically significant results were found to support the claim that an increased foot length leads to an increase in joint depth. This must be accounted for when performing these procedures. We have attempted to simplify this process by

Trephine Procedure for Revision Tarsometatarsal Arthrodesis Nonunion
2020, Clinics in Podiatric Medicine and SurgeryCitation Excerpt :Current literature is somewhat lacking regarding arthrodesis rates specific to midfoot fusions with the trephine technique. Ryan and colleagues10 performed a cadaveric study to aid in the process of joint preparation by looking at average depth of the Lisfranc joint. After studying 51 specimens they determined the average depth of the first metatarsal-cuneiform joint to be 32.3 mm, the second metatarsal-cuneiform joint to be 26.9 mm, and the third metatarsal-cuneiform joint to be 23.6 mm.
