One of the early designs was a contoured (Luque) rod fixated with wires, the so-called Hartshill-Ransford loop. In this study, the authors report their 20-year experience with this surgical technique in children.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Methods<\/jats:title>\n<jats:p>The authors reviewed the medical records of patients 18 years of age or younger who underwent dorsal occipitocervical fusion procedures between March 1992 and March 2012 at Le Bonheur Children's Hospital using a contoured rod and wire construct. Data on basic patient characteristics, causes of instability, neurological function at presentation and at last follow-up, details of surgery, complications, and radiographic outcome were collected.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Results<\/jats:title>\n<jats:p>Twenty patients (11 male) were identified, with a mean age of 5.5 years (range 1\u201318 years) and a median follow-up of 43.5 months. Fourteen patients had atlantooccipital dislocation, 2 patients had atlantoaxial fracture\u2013dissociations, 2 had Down syndrome with occipitocervical and atlantoaxial instability, 1 had an epithelioid sarcoma from the clivus to C-2, and 1 had an anomalous atlas with resultant occipitocervical instability. Surgical stabilization extended from the occiput to C-1 in 3 patients, C-2 in 6, C-3 in 8, and to C-4 in 3. Bone morphogenetic protein was used in 2 patients. Two patients were placed in a halo orthosis; the rest were kept in a hard collar for 6\u20138 weeks. All patients were neurologically stable after surgery. One patient with a dural tear experienced wound dehiscence with CSF leakage and required reoperation. Eighteen patients went on to achieve fusion within 6 months of surgery; 1 patient was initially lost to follow-up, but recent imaging demonstrated a solid fusion. There were no early hardware or bone failures requiring hardware removal, but radiographs obtained 8 years after surgery showed that 1 patient had an asymptomatic fractured rod. There were no instances of symptomatic junctional degeneration, and no patient was found to have increasing lordosis over the fused segments. Five (31%) of the 16 trauma patients required a shunt for hydrocephalus.<\/jats:p><\/jats:sec>\n<jats:sec>\n<jats:title>Conclusions<\/jats:title>\n<jats:p>Despite the proliferation of screw-fixation techniques for craniocervical instability in children, the contoured rod\u2013wire construct remains an effective, less expensive, and technically easier alternative that has been in use for almost 30 years. It confers immediate stability, and therefore most patients will not need to be placed in a halo device postoperatively. A secondary observation in our series was the high (30%) rate of hydrocephalus requiring a shunt in patients with traumatic instability.<\/jats:p><\/jats:sec>","DOI":"10.3171\/2012.9.peds12214","type":"journal-article","created":{"date-parts":[[2012,11,16]],"date-time":"2012-11-16T15:03:43Z","timestamp":1353078223000},"page":"160-169","source":"Crossref","is-referenced-by-count":23,"title":["Occipitocervical fusion using a contoured rod and wire construct in children: a reappraisal of a vintage technique"],"prefix":"10.3171","volume":"11","author":[{"given":"Paul","family":"Klimo","sequence":"first","affiliation":[{"name":"Semmes-Murphey Neurologic & Spine Institute;"},{"name":"Department of Neurosurgery, University of Tennessee Health Science Center;"},{"name":"Le Bonheur Children's Hospital; and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nelson","family":"Astur","sequence":"additional","affiliation":[{"name":"Campbell Clinic, Memphis, Tennessee"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyle","family":"Gabrick","sequence":"additional","affiliation":[{"name":"Semmes-Murphey Neurologic & Spine Institute;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William C.","family":"Warner","sequence":"additional","affiliation":[{"name":"Campbell Clinic, Memphis, Tennessee"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael S.","family":"Muhlbauer","sequence":"additional","affiliation":[{"name":"Semmes-Murphey Neurologic & Spine Institute;"},{"name":"Department of Neurosurgery, University of Tennessee Health Science Center;"},{"name":"Le Bonheur Children's Hospital; and"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1-peds12214","series-title":"Childs Nerv Syst","doi-asserted-by":"publisher","first-page":"1209","DOI":"10.1007\/s00381-008-0607-7","article-title":"Fusions at the craniovertebral junction","volume":"24","author":"Ahmed","year":"2008"},{"issue":"1 Suppl","key":"b2-peds12214","series-title":"J Neurosurg","first-page":"36","article-title":"Selection of a rigid internal fixation construct for stabilization at the craniovertebral junction in pediatric patients","volume":"107","author":"Anderson","year":"2007"},{"key":"b3-peds12214","series-title":"J Neurosurg Spine","doi-asserted-by":"publisher","first-page":"143","DOI":"10.3171\/SPI\/2008\/8\/2\/143","article-title":"Biomechanical comparison of occipitoatlantal screw fixation techniques","volume":"8","author":"Bambakidis","year":"2008"},{"key":"b4-peds12214","series-title":"J Neurosurg Pediatr","doi-asserted-by":"publisher","first-page":"475","DOI":"10.3171\/2011.2.PEDS10331","article-title":"Use of occipital bone graft in pediatric posterior cervical fusion: an alternative paramedian technique and review of the literature.
