Nervus obturatorius

Nervus obturatorius

Cursus nervi obturatorii (flave).

Nervus obturatorius (TA: 14.2.07.012) est nervus periphericus ex plexu lumbali oriente. Nervus adductores femoris innervat, simul pars cutis femoris medialis et capsulae anterioris articularis coxae nervo innervata est. Pro eo nervus de pelvi trans foramen obturatum antrorsum in femorem decurrit.

Cursus nervi femoralis

Ex plexu lumbali (radicibus L₂-L₄) oriente nervus obturatorius sub musculum psoas maiorem deorsum, post arteriam iliacam internam et iuxta ureterem in canalem obturatorium intrat, quo cum ramis et anteriore et posteriore ad adductores femoris currit. Ex ramo anteriore ramus cutaneus et plures rami musculares, ex ramo posteriore rami musculares atque ramus articularis oriuntur. Paralysis nervi implantatione prothesis capitis femoris ineunte causa raro observata est^[1].

Musculi innervati

Musculus obturator externus
Musculus adductor longus
Musculus adductor brevis
Musculus adductor magnus (una cum nervi tibiali)
Musculus gracilis
Musculus pectineus (una cum nervo femorali, innervatio nervi obturatorii accessorii non constanter, ca. 20%)

Significatio medica

Resectione transurethrali tumorum vesicae ineunte non raro ruptura vesicae observata est, et ibi obsidio pharmacologica nervi oburatorii contractionem dolorosam adductorum impedit^[2].
