The authors report a method for programming jammed Codman Hakim programmable valves by using a Strata II magnet and additional neodymium magnets. The programming method was derived after studying a jammed valve in the laboratory that was explanted from an 10-year-old boy with a history of fourth ventricle ependymoma. Programming the explanted valve with a Codman programmer failed, but rotating a Strata II magnet above the valve resulted in rotation of the spiral cam in the valve. It was found that the Strata II magnet could be used to program the jammed valve by rotating the magnet 90\u00b0 or multiples of 90\u00b0 above the valve. The strength of the magnetic field of the Strata II magnet was able to be increased by putting neodymium magnets on it. The programming method was then successfully used in a patient with a jammed Codman Hakim programmable valve. After successful programming using this method, clinical and radiological follow-up of the patient was advised.<\/jats:p>","DOI":"10.3171\/2013.4.peds12461","type":"journal-article","created":{"date-parts":[[2013,5,24]],"date-time":"2013-05-24T14:03:15Z","timestamp":1369404195000},"page":"160-165","source":"Crossref","is-referenced-by-count":0,"title":["Programming jammed Codman Hakim programmable valves: study of an explanted valve and successful programming in a patient"],"prefix":"10.3171","volume":"12","author":[{"given":"Sui-To","family":"Wong","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eleanor","family":"Wen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dawson","family":"Fong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1-peds12461","series-title":"Neurosurgery","first-page":"1110","article-title":"The use of the Codman-Medos Programmable Hakim valve in the management of patients with hydrocephalus: illustrative cases","volume":"34","author":"Black","year":"1994"},{"key":"b2-peds12461","series-title":"Procedure Guide.
