The purpose of this study is to 1) describe the outcomes in patients treated with VBG combined with unloading procedures, 2) compare the outcomes according to the unloading procedures and 3) find any radiologic parameters affecting revascularization in Kienb\u00f6ck disease. <\/jats:p><jats:p> Methods: A retrospective review was performed involving in 20 patients undergoing 4<jats:sup>th<\/jats:sup> and 5<jats:sup>th<\/jats:sup> extensor compartmental VBG with unloading procedures for Kienb\u00f6ck disease from 2010\u20132015. After VBG in all patients, unloading procedures were additionally performed depending on the ulnar variance. These additional operations included joint leveling procedures (radial and capitate shortening osteotomy) or temporary scaphocapitate pinning. Radiologic outcome was evaluated according to Lichtman stage and presence of revascularization evidence. Clinical evaluations included wrist range of motion, grip strength, visual analogue scale (VAS), and Mayo wrist score. <\/jats:p><jats:p> Results: VBG with joint leveling procedures was performed in 11 patients (5 radial shortening and 6 capitate shortening) and VBG with temporary scaphocapitate pinning was performed in 9 patients. Although clinical outcomes were not significantly different according to the unloading procedures, there were significantly more patients with evidence of healing of osteonecrosis on radiographs in joint leveling procedure group than temporary scaphocapitate pinning group. Overall, evidence of healing of osteonecrosis was found on plain radiographs in 11 patients and was not found in 9 patients. However, there were no significant preoperative radiological parameters affecting revascularization on radiographs. <\/jats:p><jats:p> Conclusions: Not all patients had evidence of revascularization on radiography after VBG combined with unloading procedures for Kienb\u00f6ck disease. However, among the unloading procedures, joint-leveling procedures positively influenced the revascularization process. <\/jats:p>","DOI":"10.1142\/s2424835519500541","type":"journal-article","created":{"date-parts":[[2019,11,6]],"date-time":"2019-11-06T07:04:01Z","timestamp":1573023841000},"page":"428-434","source":"Crossref","is-referenced-by-count":3,"title":["Is Joint Levelling Procedure Better than Temporary Scaphocapitate Pinning in Patients Undergoing Vascularized Bone Graft for Kienb\u00f6ck Disease?"],"prefix":"10.1142","volume":"24","author":[{"given":"Hyoung Seok","family":"Jung","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, Medical Center of Chung-Ang University School of Medicine, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ho Won","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Min Jong","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2019,11,5]]},"reference":[{"key":"p_1","doi-asserted-by":"publisher","DOI":"10.1067\/j.cpradiol.2017.04.012"},{"key":"p_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13018-015-0276-7"},{"key":"p_3","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2008.10.014"},{"key":"p_4","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2004.10.002"},{"key":"p_5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2012.11.016"},{"key":"p_6","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2010.09.014"},{"key":"p_8","doi-asserted-by":"publisher","DOI":"10.1097\/BPB.0000000000000165"},{"key":"p_9","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2018.01.008"},{"key":"p_10","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(10)80156-X"},{"key":"p_11","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2014.12.024"},{"key":"p_12","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2009.06.017"},{"key":"p_13","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(09)90016-8"},{"key":"p_15","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2008.04.006"},{"key":"p_16","first-page":"956369","volume":"2014","author":"Dehghani M","year":"2014","journal-title":"Int Sch Res Notices."},{"key":"p_17","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2017.06.107"},{"key":"p_18","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(97)80003-2"},{"key":"p_19","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2005.03.019"},{"key":"p_20","doi-asserted-by":"publisher","DOI":"10.1016\/S0363-5023(03)00490-8"},{"key":"p_22","doi-asserted-by":"publisher","DOI":"10.5435\/00124635-200103000-00006"},{"key":"p_23","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2007.11.005"},{"key":"p_24","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhsa.2008.10.015"}],"container-title":["The Journal of Hand Surgery (Asian-Pacific Volume)"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.worldscientific.com\/doi\/pdf\/10.1142\/S2424835519500541","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,11,6]],"date-time":"2019-11-06T07:04:17Z","timestamp":1573023857000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.worldscientific.com\/doi\/abs\/10.1142\/S2424835519500541"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,11,5]]},"references-count":21,"journal-issue":{"issue":"04","published-print":{"date-parts":[[2019,12]]}},"alternative-id":["10.1142\/S2424835519500541"],"URL":"https:\/\/doi.org\/10.1142\/s2424835519500541","relation":{},"ISSN":["2424-8355","2424-8363"],"issn-type":[{"value":"2424-8355","type":"print"},{"value":"2424-8363","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,11,5]]}}}
