  5. Articulatiocubiti: 3 jointsinside of a commoncapsule Sobotta • Humeroradialjoint: • ball-and-socketjoint • (articulatio spheroidea) • 3 axises • Doesnothave important • function • Humeroulnarjoint: • hingejoint(ginglymus) • 1 axis: transversal + Sobotta • Proximalradioulnarjoint: • pivotjoint (trochoid) • 1 axis: longitudinal Articulatiocubiti: trochoginglymus Articulatio radioulnaris distalis

  6. Jointcapsule fibrouslayer Sobotta zsírszövet synoviallayer Thiel Capsule: antero-posteriorly: loose laterally:tight (collateralligaments!) • origin: anteriorlyabovethecoronoid fossa and radial fossa • posteriorly: abovetheolecranon fossa. • medial and lateralepicondylesare out of thecapsule!!!! Musclesareoriginatingfromthere!!! • insertion: belowthecoronoidprocess of theulna; • 1.5 cm belowthearticularcircumference of theradius • (forthepronation-supination: recessussacciformis (sup)

  7. Ligaments: ulnar and radialcollateralligaments Anteriorview M. brachialis tapadása lateralview medialview pars ant.; pars post.; p. Cooperi = pars transversa [lig. olecranocoronoideum]

  8. Ligaments Sobotta Thiel Ulnar (medial) collateral ligament (mediale): pars anterior (band-like) pars posterior (fun-shaped) parstransversa /lig. olecranocoronoideum (Cooper) Sobotta
