Occasionally a direct blow will cause fracture of the inferior pole of the patella, but the only other mechanism which seems to be respon sible is subluxation or dislocation. Ten cases of distal patellar pole fracture secondary to dislocation or sub luxation of the patella are reported. From these cases and an extensive review of the literature it is concluded that patellar subluxation or dislocation is the usual common mechanism of distal patellar pole fractures in young, active individuals and that adequate treatment of this problem must address the patellar instability as well as the fracture.<\/jats:p>","DOI":"10.1177\/036354658401200603","type":"journal-article","created":{"date-parts":[[2007,6,21]],"date-time":"2007-06-21T20:46:52Z","timestamp":1182458812000},"page":"424-428","source":"Crossref","is-referenced-by-count":26,"title":["Distal patellar pole fractures"],"prefix":"10.1177","volume":"12","author":[{"given":"James D.","family":"Heckman","sequence":"first","affiliation":[{"name":"Department of Orthopaedics, University of Texas Health Science Center at San Antonio, San Antonio, Texas"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carey C.","family":"Alkire","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, University of Texas Health Science Center at San Antonio, San Antonio, Texas"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1984,11,1]]},"reference":[{"key":"atypb1","unstructured":"Beddow FH, Corkery PH, Shatwell GL Avulsion of the ligamentum patellae from the lower pole of the patella J R Coll Surg Edinb 9 66-69, 1963"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1016\/S0030-5898(20)32343-9"},{"key":"atypb3","doi-asserted-by":"crossref","unstructured":"Coleman HM Recurrent osteochondral fracture of the patella J Bone Joint Surg 30B 153-157, 1948","DOI":"10.1302\/0301-620X.30B1.153"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1177\/036354658301100202"},{"key":"atypb5","unstructured":"Harmon PH Intra-articular osteochondral fractures as a cause for Internal derangement of the knee In adolescents J Bone Joint Surg 27 703-705, 1945"},{"key":"atypb6","unstructured":"Hawley GW, Gnswold AS Larsen-Johansson's disease of the patella Surg Gynecol Obstet 47 68-72, 1928"},{"key":"atypb7","unstructured":"Hohl M.
