The authors report the case of a 50-year-old woman who presented with low-back pain and right leg radiating pain of 1 year\u2019s duration. Radiological studies revealed a spontaneous bilateral pedicle fracture of L-5. All efforts at conservative treatment failed, and the patient underwent surgery for osteosynthesis of the fractured pedicle using bilateral pedicle screws connected with a bent rod. Her low-back and right leg pain were relieved postoperatively. A CT scan performed 3 months postoperatively revealed the disappearance of the pedicle fracture gap and presence of newly formed bony trabeculation. In rare cases of spontaneous bilateral pedicle fracture of the lumbar spine, osteosynthesis of the fractured pedicle using bilateral pedicle screws and a bent rod is a motion-preserving technique that may be an effective option when conservative management has failed.<\/jats:p>","DOI":"10.3171\/2015.7.spine141207","type":"journal-article","created":{"date-parts":[[2015,11,20]],"date-time":"2015-11-20T15:01:36Z","timestamp":1448031696000},"page":"398-401","source":"Crossref","is-referenced-by-count":11,"title":["Posterior osteosynthesis of a spontaneous bilateral pedicle fracture of the lumbar spine"],"prefix":"10.3171","volume":"24","author":[{"given":"Sang-Hyun","family":"Han","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seung-Jae","family":"Hyun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tae-Ahn","family":"Jahng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ki-Jeong","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1-spine141207","series-title":"Skeletal Radiol","doi-asserted-by":"publisher","first-page":"221","DOI":"10.1007\/BF00350578","article-title":"Jogger\u2019s fracture and other stress fractures of the lumbo-sacral spine","volume":"13","author":"Abel","year":"1985"},{"key":"b2-spine141207","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"E1360","DOI":"10.1097\/BRS.0b013e318206cf63","article-title":"Posterior osteosynthesis of the atlas for nonconsolidated Jefferson fractures: a new surgical technique","volume":"36","author":"Abeloos","year":"2011"},{"key":"b3-spine141207","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"1424","DOI":"10.1097\/00007632-199211000-00028","article-title":"Reactive sclerosis of the pedicle associated with contralateral spondylolysis","volume":"17","author":"Araki","year":"1992"},{"key":"b4-spine141207","series-title":"J Bone Joint Surg Br","doi-asserted-by":"publisher","first-page":"234","DOI":"10.1302\/0301-620X.60B2.659472","article-title":"The fatigue strength of the lumbar neural arch in spondylolysis","volume":"60-B","author":"Cyron","year":"1978"},{"key":"b5-spine141207","series-title":"J Bone Joint Surg Br","doi-asserted-by":"publisher","first-page":"462","DOI":"10.1302\/0301-620X.58B4.1018032","article-title":"Spondylolytic fractures","volume":"58-B","author":"Cyron","year":"1976"},{"key":"b6-spine141207","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"63","DOI":"10.1097\/00007632-198601000-00018","article-title":"Unilateral spondylolysis and contralateral pedicle fracture","volume":"11","author":"Garber","year":"1986"},{"key":"b7-spine141207","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"2541","DOI":"10.1097\/00007632-200010010-00019","article-title":"Contralateral spondylolysis and fracture of the lumbar pedicle in an elite female gymnast: a case report","volume":"25","author":"Guillodo","year":"2000"},{"key":"b8-spine141207","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"E158","DOI":"10.1097\/01.BRS.0000058951.16468.24","article-title":"Bilateral pedicle stress fracture after instrumented posterolateral lumbar fusion: a case report","volume":"28","author":"Ha","year":"2003"},{"key":"b9-spine141207","series-title":"J Clin Neurosci","doi-asserted-by":"publisher","first-page":"695","DOI":"10.1016\/j.jocn.2010.08.033","article-title":"Motion-preserving reduction and fixation of C1 Jefferson fracture using a C1 lateral mass screw construct","volume":"18","author":"Jo","year":"2011"},{"key":"b10-spine141207","series-title":"J Neurosurg Spine","doi-asserted-by":"publisher","first-page":"724","DOI":"10.3171\/2009.7.SPINE08373","article-title":"Stress fracture of the lumbar pedicle bilaterally: surgical repair using a percutaneous minimally invasive technique","volume":"11","author":"Johnson","year":"2009"},{"key":"b11-spine141207","series-title":"Spine (Phila Pa 1976)","doi-asserted-by":"publisher","first-page":"849","DOI":"10.1097\/00007632-199207000-00023","article-title":"Idiopathic scoliosis with unusual stress fracture of the pedicle within solid fusion mass.
