All patients were competing at some level of sport and were assessed preoperatively and postoperatively using the Foot and Ankle Outcome Score and SF-12 outcome scores. The mean follow-up time was 20.62 months (range, 12-28). Of the 26 fractures, 17 were traditional zone II Jones fractures, and the remaining 9 were zone III proximal diaphyseal fractures.<\/jats:p>\n                  <jats:p>Results: The mean Foot and Ankle Outcome Score significantly increased, from 51.15 points preoperatively (range, 14-69) to 90.91 at final follow-up (range, 71-100; P &lt; .01). The mean physical component of the SF-12 score significantly improved, from 25.69 points preoperatively (range, 6-39) to 54.62 at final follow-up (range, 32-62; P &lt; .01). The mean mental component of the SF-12 score also significantly improved, from 28.20 points preoperatively (range, 14-45) to 58.41 at final follow-up (range, 36-67; P &lt; .01). The mean time to fracture healing on standard radiographs was 5 weeks after surgery (range, 4-24). Two patients did not return to their previous levels of sporting activity. One patient experienced a delayed union, and 1 healed but later refractured.<\/jats:p>\n                  <jats:p>Conclusion: Percutaneous internal fixation of proximal fifth metatarsal Jones fractures, with a Charlotte Carolina screw and bone marrow aspirate concentrate, provides more predictable results while permitting athletes a return to sport at their previous levels of competition, with few complications.<\/jats:p>","DOI":"10.1177\/0363546510393306","type":"journal-article","created":{"date-parts":[[2011,1,6]],"date-time":"2011-01-06T23:40:30Z","timestamp":1294357230000},"page":"1295-1301","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":91,"title":["Percutaneous Internal Fixation of Proximal Fifth Metatarsal Jones Fractures (Zones II and III) With Charlotte Carolina Screw and Bone Marrow Aspirate Concentrate"],"prefix":"10.1177","volume":"39","author":[{"given":"Christopher D.","family":"Murawski","sequence":"first","affiliation":[{"name":"Hospital for Special Surgery, New York, New York."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John G.","family":"Kennedy","sequence":"additional","affiliation":[{"name":"Hospital for Special Surgery, New York, New York."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2011,1,6]]},"reference":[{"key":"bibr1-0363546510393306","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-192708000-00020"},{"key":"bibr2-0363546510393306","doi-asserted-by":"publisher","DOI":"10.1007\/s11999-008-0222-7"},{"key":"bibr3-0363546510393306","first-page":"238","volume":"315","author":"Clapper MF","year":"1995","journal-title":"Clin Orthop Relat Res"},{"key":"bibr4-0363546510393306","doi-asserted-by":"publisher","DOI":"10.1002\/jor.20112"},{"key":"bibr5-0363546510393306","doi-asserted-by":"publisher","DOI":"10.5435\/00124635-199503000-00006"},{"key":"bibr6-0363546510393306","doi-asserted-by":"publisher","DOI":"10.1177\/036354658301100513"},{"key":"bibr7-0363546510393306","doi-asserted-by":"publisher","DOI":"10.5435\/00124635-200907000-00006"},{"key":"bibr8-0363546510393306","doi-asserted-by":"publisher","DOI":"10.1016\/j.csm.2005.08.014"},{"key":"bibr9-0363546510393306","unstructured":"Hansen STJr. Functional Reconstruction of the Foot and Ankle.
