The purpose of this study was to confirm the superior strength of a rigid stepped plate as compared to a 4-hole L-plate device.<\/jats:p>\n          <jats:p>\n            Lateral closing-wedge high tibial osteotomy was performed on 30 ten-month-old porcine tibiae. Fifteen tibiae were fixed using a rigid stepped plate and 15 were fixed with a 4-hole L-plate. Three types of deforming force\u2014compression, valgus bending, and varus bending\u2014were each applied to 5 pair of tibiae fitted with either the rigid stepped plate or the L-plate using a mechanical testing apparatus. Values of load, displacement, and stiffness were analyzed to compare the fixation powers. Mean stiffness in the rigid stepped plate and L-plate groups were 977.8 (SD 230.3) and 836.2 (SD 248.4) N\/mm for compression testing (\n            <jats:italic>P<\/jats:italic>\n            =.465), 38.7 (SD 12.9) and 21.6 (SD 9.6) N\/mm for valgus bending (\n            <jats:italic>P<\/jats:italic>\n            =.047), and 62.3 (SD 18.1) and 29.8 (SD 9.7) N\/mm for varus bending (\n            <jats:italic>P<\/jats:italic>\n            =.009), respectively.\n          <\/jats:p>\n          <jats:p>The rigid stepped plate has greater fixation strength than the conventional 4-hole L-plate. Given this improved level of fixation with the rigid stepped plate, immobilization duration after high tibial osteotomy could be shortened and complications reduced.<\/jats:p>","DOI":"10.3928\/01477447-20090818-08","type":"journal-article","created":{"date-parts":[[2009,10,16]],"date-time":"2009-10-16T18:31:07Z","timestamp":1255717867000},"page":"728-733","source":"Crossref","is-referenced-by-count":2,"title":["Rigid Stepped Plate for Internal Fixation for High Tibial Osteotomy"],"prefix":"10.3928","volume":"32","author":[{"given":"Jae Ho","family":"Yoo","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sang Cheol","family":"Seong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sahnghoon","family":"Lee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kuiwon","family":"Choi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Moon Kyu","family":"Lee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Changyang","family":"Lee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Myung Chul","family":"Lee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2308","reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"crossref","unstructured":"Coventry MB.
