However, advanced age and osteoporosis are 2 risk factors for pseudarthrosis. Kyphoplasty has been described in the treatment of lytic lesions in C-2. The authors decided to combine these 2 techniques in the treatment of unstable fractures of the odontoid.<\/jats:p>\n<jats:p>Two approximately 90-year-old patients were treated for this type of fracture. Instability was demonstrated on dynamic radiography in one patient, and the fracture was seen on static radiography in the other. Clinical parameters, pain, range of motion, 36-Item Short Form Health Survey (SF-36) score (for the first patient), and radiological examinations (CT scans and dynamic radiographs) were studied both before and after surgery.<\/jats:p>\n<jats:p>After inflating the balloon both above and below the fracture line, the authors applied a high-viscosity polymethylmethacrylate cement. Some minor leakage of cement was noted in both cases but proved to be harmless. The screws were correctly positioned. The clinical result was excellent, both in terms of pain relief and in the fact that there was no reduction in the SF-36 score. The range of motion remained the same. A follow-up CT scan obtained 1 year later in one of the patients showed no evidence of change in the materials used, and the dynamic radiographs showed no instability.<\/jats:p>\n<jats:p>This combination of kyphoplasty and anterior screw fixation of the odontoid seems to be an interesting technique in osteoporotic Type IIB fractures of the odontoid process in the elderly, with good results both clinically and radiologically.<\/jats:p>","DOI":"10.3171\/2014.11.spine131013","type":"journal-article","created":{"date-parts":[[2015,1,2]],"date-time":"2015-01-02T14:59:58Z","timestamp":1420210798000},"page":"246-252","source":"Crossref","is-referenced-by-count":6,"title":["Odontoid balloon kyphoplasty associated with screw fixation for Type II fracture in 2 elderly patients"],"prefix":"10.3171","volume":"22","author":[{"given":"Luc","family":"Terreaux","sequence":"first","affiliation":[{"name":"Department of Neurosurgery and Neurotraumatology, Nantes University Hospital; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Loubersac","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery and Neurotraumatology, Nantes University Hospital; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olivier","family":"Hamel","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery and Neurotraumatology, Nantes University Hospital; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric","family":"Bord","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery and Neurotraumatology, Nantes University Hospital; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roger","family":"Robert","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery and Neurotraumatology, Nantes University Hospital; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kevin","family":"Buffenoir","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery and Neurotraumatology, Nantes University Hospital; and"},{"name":"INSERM EA 3826, Pain, Neuromodulation and Quality of Life, Nantes, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-spine131013","series-title":"Neurosurgery","first-page":"676","article-title":"Surgical vs nonoperative treatment of Hadley type IIA odontoid fractures","volume":"70","author":"Aldrian","year":"2012"},{"key":"b2-spine131013","series-title":"J Bone Joint Surg Am","doi-asserted-by":"publisher","first-page":"1663","DOI":"10.2106\/00004623-197456080-00017","article-title":"Fractures of the odontoid process of the axis","volume":"56","author":"Anderson","year":"1974"},{"key":"b3-spine131013","series-title":"Pain Physician","first-page":"35","article-title":"Vertebroplasty using transoral approach in painful malignant involvement of the second cervical vertebra (C2): a single-institution series of 25 patients","volume":"15","author":"Anselmetti","year":"2012"},{"key":"b4-spine131013","series-title":"Eur Radiol","doi-asserted-by":"publisher","first-page":"850","DOI":"10.1007\/s00330-006-0283-5","article-title":"Minimally invasive treatment of C2 odontoid traumatic fracture with transoral percutaneous vertebroplasty","volume":"17","author":"Anselmetti","year":"2007"},{"key":"b5-spine131013","series-title":"Clin Neurol Neurosurg","doi-asserted-by":"publisher","first-page":"2056","DOI":"10.1016\/j.clineuro.2013.07.006","article-title":"Elderly patients are at increased risk for mortality undergoing surgical repair of dens fractures","volume":"115","author":"Ardeshiri","year":"2013"},{"key":"b6-spine131013","series-title":"Unfallheilkunde","first-page":"221","article-title":"[Screw-osteosynthesis of fractures of the dens axis (author's transl)]","volume":"84","author":"B\u00f6hler","year":"1981"},{"key":"b7-spine131013","series-title":"J Bone Joint Surg Am","doi-asserted-by":"publisher","first-page":"1340","DOI":"10.2106\/00004623-198567090-00006","article-title":"Fractures of the dens.
