• Wiig, Ola; Wensaas, Anders; Høiness, Per Reidar & Horn, Joachim (2011). Kirurgisk dislokasjon av hoften ved epifysiolysis capitis femoris. Show summary

  Bakgrunn: Behandlingen av epifyseolysis capitis femoris har i de aller fleste tilfeller bestått i forsiktig reposisjon og fiksasjon in situ med skruer eller pinner. Åpne prosedyrer har tradisjonelt vært assosiert med høy risiko for avaskulær nekrose. Ganz et al. (2001) publiserte en artikkel som omhandlet kirurgisk dislokasjon av hoften der han demonstrerte en teknikk med full tilgang til caput femoris og acetabulum uten risiko for avaskulær nekrose. Denne teknikken har i økende grad blitt tatt i bruk i behandlingen av epifyseolysis capitis femoris. Materiale og metoder: Vi beskriver teknikken og presenterer to pasienter med epifyseolysis capitis femoris som er operert med kirurgisk dislokasjon av hoften. Pasient 1: 14 år gammel jente som var plaget med intermitterende hoftesmerter i 3 uker, markert forværring siste 2 uker og hun var ute av stand til å belaste 2 dager før innleggelse. Røntgen viser epifyseolyse med stor glidning (90 grader). Initialt forsøkt lukket reposisjon uten hell. Operert med åpen dislokasjon av venstre hofte med collumosteotomi, reposisjon av epifysen og fiksasjon med 2 skruer. Smertefri med normal gangfunksjon og ingen tegn til caputnekrose radiologisk 1 1/2 år etter inngrepet. Pasient 2: 12 år gammel med ubehag høyre hofte 9 måneder forut for innleggelse. Tolket som en kronisk epifyseolyse med stor glidning. Operert med åpen reposisjon, collumosteotomi og pinnefiksering. 5 uker postoperativt fall og smerter. Påvist hofteluksjasjon. Reoperert med åpen reposisjon. Det var pinneperforasjon og bruskdefekt på caput. Ingen smerter og god bevegelighet 3 måneder etter primæroperasjon, men røntgen viser lav leddspalte og defekt på caput. Diskusjon: Kirurgisk dislokasjon av hoften gir god oversikt over caput femoris og acetabulum. Utført korrekt er det rapportert lav risiko for avaskulær nekrose. Det foreligger ingen enighet om indikasjonene for kirurgisk dislokasjon av hoften ved epifyseolysis capitis femoris. Etter vår mening vil det være fornuftig å reservere denne teknikken til de store irreponible akutte glidningene. Ved uttale kroniske eller akutt på kroniske epifyseolyser bør man overveie in situ fiksasjon og senere proksimal femurosteotomi dersom det er behov for kirurgisk korreksjon.
