The Hip/Lumbar Spine Flashcards
The most proximal joint of the lower extremity
The Hip
The femur is the convex ball an the acetabular is the what?
concave socket
The hip is very stable and when you have stability, you sacrifice what?
flexibility
motion in all three planes
Triaxial joint
The four bones of the hips are collectively known as the pelvis
Os coxae x 2 (innominates)
Sacrum
Coccyx
The sacrum is then connected to the ??
coccyx
The two hip bones are connected to each other in the front by the________ _________ and posteriorly to the ________.
- pubic symphysis
- sacrum
The oscoxae is made up of 3 bones together
- Ilium
- ischium
- pubis
large, concave area on the internal surface to which the iliopsoas muscle attaches
Iliac fossa
the bony part of your hips that your hands rest on when you have your hands on your hips
Iliac crest
projection on the anterior end of the iliac crest
TFL, sartorius, inguinal ligament
ASIS
projection just inferior to the ASIS
Rectus femoris
AIIS
posterior projection on the iliac crest
PSIS
just below the PSIS
PIIS
- Iliac fossa
- Iliac crest
- ASIS
- AIIS
- PSIS
- PIIS
Theses are landmarks of what?
Ilium
The posterior, inferior portion of the hip bone?
Ischium
makes up 2/5ths of the acetabulum.
Body
extends medially from the body to connect with the inferior ramus of the pubis
- Adductor magnus
- Obturator externus
- Obturator internus
Ramus
rough, blunt projection of the inferior part of the body
- Weight bearing when you are sitting
- Hamstrings
- Adductor magnus
Ischial tuberosity
Located on the posterior portion of the body between the greater and lesser sciatic notches
Spine
- Body
- Ramus
- Ischial tuberosity
- Spine
Bony landmarks of what?
Ischium
externally forms 1/5th of the acetabulum and internally provides attachments for the obturator internus
Body
lies superior between the acetabulum and the body, provides attachment for the pectineus
Superior Ramus
lies posterior, inferior and lateral to the pubic body,
attachment for
- adductor magnus,
- gracilis,
- adductor brevis
Inferior Ramus
cartilagenous joint connecting the bodies of the two pubic bones
Symphysis pubis
projects anteriorly on the superior ramus near the symphysis pubis and provides attachment for the inguinal ligament
Pubic tubercle
- Body
- Superior ramus
- inferior ramus
- symphysis pubis
- pubic tubercle
bondy landmarks of what?
Pubis
just below the PIIS and is made into a foramen by the sacrospinous ligament.
- Sciatic nerve, piriformis and other structures pass through this foramen
Greater sciatic notch
the longest and strongest bone in the body and a person’s height can be determined by 4 times the length of this bone
- Head – rounded portion covered with articular cartilage
- Neck – narrower portion located between the head and the trochanters
- Greater trochanter – large projection located laterally between the neck and the body
- Provides attachments for gluteus medius, minimus and the deep rotator muscles
femur
smaller projection medial and posterior and just distal to the greater trochanter provides attachments for iliopsoas
lesser trochanter
small projection on the femur just proximal to the medial epicondyle
- A small portion of the adductor magnus attaches here
Adductor tubercle
prominent longitudinal ridge or crest along the posterior length of the bone
Linea aspera
runs from below the lesser trochanter diagonally toward the linea aspera
- Adductor brevis attaches in this area
Pectineal line
between the medial and lateral condyles and articulates with the posterior surface of the patella
Patellar surface
Tibial- large projection at the proximal end in the midline, provides attachment for the patellar tendon
Tibial tuberosity
