3rd colloquim -luut Flashcards
Os coxae consists of three bones? And what do they form together? What are its’ parts? By what are these bones joined together at first and what is it replaced by later on when older?
Os ilium
Os pubis
Os ischia
ACETABULUM:
- Fossa acetabuli
- facies lunata
- incisura acetabuli
- foramen obturatum
Up until the age of 16 years these bones are joined together by synchondrosis, which is later replaced by
synostosis.
Tell me about os ilium
Two parts: Corpus ilii and ala ossis ilii —> linea arcuata
Ala ossis ilii
- crista iliaca
- Spina iliaca anterior superior/inferior
- Fossa iliaca
Facies glutea: linea glutea posterior/anterior/inferior
Posterior region:
- Facies sacropelvina
- Facies auricularis
- tuberositas iliaca
Tell me about os ischii
2 parts: corpus ossis ischii (forms posterior 1/3 of acetabulum), ramus ossis ischii (fuses with
ramus inferior ossis pubis).
Ramus:
- tuber ischiadicum
- spina ishiadica
- incisura ischiadica minor/major
Tell me about os pubis
3 parts: corpus ossis pubis (forms anterior 1/3 of acetabulum), ramus superior ossis pubis and
ramus inferior ossis pubis.
Superior:
- pecten ossis pubis
- sulcus obturatorius
- tuberculum pubicum
- facies symphialis
What synchondrosis is in the lower Limb?
Until age of 16 between corpus os ilium, os ischii, os pubis. Can be also found between Ramus ossis ischii and Ramus inferior ossis pubis
What syndesmoses are there in the lower limb?
- MEMBRANA obturatoria (closes foramen obturatum expect sulcus obturatorius for blood vessels and nervers passes canalis obturatorius)
-> lig. Sacrospinale (os sacrum to spina ischiadica)
-> lig. Sacrotuberale (os sacrum to tuber ischiadicum)
What diarthroses are in the pelvis?
Art. Sacroiliac (art.plana, amphiarthrosis)
B. Facies auricularis ossis ilii/sacri
-> capsula articularis
-> lig. Sacroiliacum anterius/posterius/interosseum
What hemiarthrosis are in pelvis? What does it translate to in English?
Transitional joint:
Symphysis pubica
B. Facies symphysialis ossis pubis. They are joined by fibrous cartilage and discus interpubicus
-> lig. pubicum superius/inferior
—> posterior surface has eminentia retropubica
Pelvis major walls and measurements
ASK FROM KNIPSE more specific ones!!
Pars posterior: vertebra lumbales 4-5 and junctions between them
Pars lateralis: ala ossis ilii dextra and sinistra
- Distantia intercristalis: crista iliaca dextra et sinistra, 28-29cm
- Distantia interspinosum: spina iliaca anterior superior dextra et sinistra, 25-27cm
- Distantia interchaterica: between trochanter major dextra and sinistra, 30-32cm
What is between pelvis minor and major ?
Linea terminalis
Apertura pelvis superior structures?
- Promontorium
- Art. Sacroiliaca
- Linea arcuata
- Eminentia iliopubica
- Pecten ossis pubis
- Tuberculum pubicum
- Lig. Pubicum superius
Pelvis minor walls and measurements
Paries posterior: os sacrum, os coccygis, juncture sacrococcygea
Paries laterales: foramen ischiadicum majus et minus
Paries anterior: Ramus superior and inferior ossis pubis, Ramus ossis ischii, membrana obturatoria, symphysis pubica
Measurements:
- Diameter transversa 13,5cm: furthest points of linea arcuata
- Diameter oblique: b. Art sacroiliaca and the opposite eminentia iliopubica 12,5cm
- conjugata anatomica: b. Promontorium and upper margins of symphysis pubica 11,5cm
- conjugata Vera: b. Promontorium and eminentia retropubica 10,5-11cm
- conjugata diagonalis: b. Promontorium and lower margins of symphysis pubica 12,5-13cm
What does female pelvis have compared to male?
Arcus pubicus between right and left lower Ramus inferior ossis pubis
Male has angulus subpubicus -> male is also smaller narrower and higher than female pelvis.
Apertura pelvis minor structures:
- Os coccygis
- lig.sacrotuberale
- Tuber ischiadicum
- Ramus ossis ischii
- Ramus inferior ossis pubis
- Lig. Pubicum inferius
