Our study examined two popular distal metatarsal neck osteotomies used for the relief of central metatarsalgia and the biomechanical changes that result from their use in a cadaver forefoot model. Methods: After applying 445N (100 lbs) of axially directed force, we measured plantar pressure using the TekScan HR Mat\u2122 (TekScan, Inc., South Boston, MA) in twelve paired, thawed, fresh-frozen intact cadaver legs, then after either a Weil or chevron osteotomy of the second metatarsal and finally after the addition of the same osteotomy of the third metatarsal. Results: Load in the forefoot was not significantly affected by the Weil osteotomy. A significant increase in load was produced in the first metatarsal region, and significant decreases in load were produced beneath the operated metatarsal heads after the chevron osteotomy. Average pressure in the contact area of the forefoot showed similar trends; however, load and pressure changes occurred independently, owing to the changes in contact area produced by the osteotomies. No significant changes were observed in the nonoperated metatarsal regions. Conclusions: In this model, the chevron osteotomy more effectively reduced load and plantar pressure in the operated metatarsal regions; however, increases in load and pressure were observed in the first metatarsal region. The increase in pressure without a change in load in region 3 (third metatarsal) after a Weil osteotomy of the third metatarsal was attributed to the creation of a plantar prominence. This study did not show a reduction in load transmission as a result of the Weil osteotomy, which contradicts the proposed mechanism of clinical benefit. An intact first ray likely prevents transfer of load or pressure to adjacent lesser metatarsals with chevron osteotomy.<\/jats:p>","DOI":"10.1177\/107110070502600208","type":"journal-article","created":{"date-parts":[[2017,1,11]],"date-time":"2017-01-11T16:36:50Z","timestamp":1484152610000},"page":"158-165","source":"Crossref","is-referenced-by-count":38,"title":["Plantar Pressure and Load in Cadaver Feet After a Weil or Chevron Osteotomy"],"prefix":"10.1177","volume":"26","author":[{"given":"John","family":"Snyder","sequence":"first","affiliation":[{"name":"Richmond, VA"},{"name":"Orthopaedic Research Laboratory, Departments of Orthopaedic Surgery and Biomedical Engineering, Virginia Commonwealth University, Richmond, Virginia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John","family":"Owen","sequence":"additional","affiliation":[{"name":"Richmond, VA"},{"name":"Orthopaedic Research Laboratory, Departments of Orthopaedic Surgery and Biomedical Engineering, Virginia Commonwealth University, Richmond, Virginia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer","family":"Wayne","sequence":"additional","affiliation":[{"name":"Richmond, VA"},{"name":"Orthopaedic Research Laboratory, Departments of Orthopaedic Surgery and Biomedical Engineering, Virginia Commonwealth University, Richmond, Virginia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert","family":"Adelaar","sequence":"additional","affiliation":[{"name":"Richmond, VA"},{"name":"Orthopaedic Research Laboratory, Departments of Orthopaedic Surgery and Biomedical Engineering, Virginia Commonwealth University, Richmond, Virginia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2005,2,1]]},"reference":[{"key":"bibr1-107110070502600208","doi-asserted-by":"publisher","DOI":"10.1177\/107110079801901004"},{"key":"bibr2-107110070502600208","doi-asserted-by":"publisher","DOI":"10.1007\/s001320050034"},{"key":"bibr3-107110070502600208","first-page":"320","volume-title":"In Surgery of the Foot and Ankle","volume":"1","author":"Coughlin MJ","year":"1999","edition":"7"},{"key":"bibr4-107110070502600208","doi-asserted-by":"publisher","DOI":"10.1177\/107110079902001003"},{"key":"bibr5-107110070502600208","first-page":"359","volume-title":"In Foot and Ankle Disorders","author":"Dockery GL","year":"2000"},{"key":"bibr6-107110070502600208","doi-asserted-by":"publisher","DOI":"10.1177\/107110078900900502"},{"key":"bibr7-107110070502600208","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-195840010-00005"},{"key":"bibr8-107110070502600208","doi-asserted-by":"publisher","DOI":"10.1177\/107110070302400703"},{"key":"bibr9-107110070502600208","doi-asserted-by":"publisher","DOI":"10.7547\/87507315-68-6-377"},{"key":"bibr10-107110070502600208","doi-asserted-by":"publisher","DOI":"10.1177\/107110079001000603"},{"key":"bibr11-107110070502600208","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.57B2.187"},{"key":"bibr12-107110070502600208","doi-asserted-by":"publisher","DOI":"10.1302\/0301-620X.66B2.6707057"},{"key":"bibr13-107110070502600208","doi-asserted-by":"publisher","DOI":"10.1177\/107110079801900602"},{"key":"bibr14-107110070502600208","first-page":"8","volume":"12","author":"Jacoby RP","year":"1973","journal-title":"J.
