The pain was around the left posterior paraspinal muscle and was aggravated by neck movement. There was no neurological abnormality; white cell count and inflammatory markers were slightly elevated. Radiology of the cervical spine showed calcification of C3\/4 and C4\/5 discs as well as the posterior longitudinal ligament over C3\/4. She was treated conservatively with a neck collar and Panadol syrup. No non-steroidal anti-inflammatory drug was prescribed. Two months later, calcification of the posterior longitudinal ligament had resolved and calcification at C3\/4 and C4\/5 discs and the C4 lower endplate had decreased. After one year, she was pain-free with no tenderness over her neck and had full range of neck motion and complete resolution of the calcification.<\/jats:p>","DOI":"10.1177\/1602400331","type":"journal-article","created":{"date-parts":[[2017,1,21]],"date-time":"2017-01-21T12:28:34Z","timestamp":1485001714000},"page":"424-426","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Acute Calcification of Intervertebral Disc and Posterior Longitudinal Ligament in a 7-Year-Old Girl: A Case Report"],"prefix":"10.1177","volume":"24","author":[{"given":"Churk Hang","family":"Li","sequence":"first","affiliation":[{"name":"Department of Orthopaedics and Traumatology, North District Hospital, Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tun Hing","family":"Lui","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, North District Hospital, Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wai Kit","family":"Ngai","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, North District Hospital, Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2016,12,19]]},"reference":[{"key":"bibr1-1602400331","first-page":"357","volume":"104","author":"Baron A","year":"1924","journal-title":"Jahrb Kinderh"},{"key":"bibr2-1602400331","doi-asserted-by":"publisher","DOI":"10.1007\/BF02012591"},{"key":"bibr3-1602400331","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0b013e3181c71ebe"},{"key":"bibr4-1602400331","doi-asserted-by":"publisher","DOI":"10.1016\/j.arcped.2004.09.010"},{"key":"bibr5-1602400331","doi-asserted-by":"publisher","DOI":"10.1016\/j.apmr.2005.06.009"},{"key":"bibr6-1602400331","doi-asserted-by":"publisher","DOI":"10.1007\/s00381-002-0708-7"},{"key":"bibr7-1602400331","doi-asserted-by":"publisher","DOI":"10.1007\/s00381-015-2840-1"},{"key":"bibr8-1602400331","doi-asserted-by":"publisher","DOI":"10.1097\/BSD.0b013e31820bb883"},{"key":"bibr9-1602400331","doi-asserted-by":"publisher","DOI":"10.1097\/BRS.0b013e3181faa95a"},{"key":"bibr10-1602400331","doi-asserted-by":"publisher","DOI":"10.1007\/s007010170143"},{"key":"bibr11-1602400331","doi-asserted-by":"publisher","DOI":"10.1007\/s00381-011-1431-z"},{"key":"bibr12-1602400331","doi-asserted-by":"publisher","DOI":"10.1007\/BF02208040"},{"key":"bibr13-1602400331","doi-asserted-by":"publisher","DOI":"10.1007\/s00381-009-0869-8"},{"key":"bibr14-1602400331","doi-asserted-by":"publisher","DOI":"10.1007\/s00381-010-1117-y"},{"key":"bibr15-1602400331","first-page":"6","volume":"11","author":"Mahlfeld K","year":"2002","journal-title":"J Pediatr Orthop B"}],"container-title":["Journal of Orthopaedic Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1602400331","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/1602400331","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,2]],"date-time":"2026-05-02T07:24:16Z","timestamp":1777706656000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/1602400331"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,12]]},"references-count":15,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2016,12]]}},"alternative-id":["10.1177\/1602400331"],"URL":"https:\/\/doi.org\/10.1177\/1602400331","relation":{},"ISSN":["1022-5536","2309-4990"],"issn-type":[{"value":"1022-5536","type":"print"},{"value":"2309-4990","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,12]]}}}
