Term
3 parts of the pelvis
Definition
ilium, ischum, and pubis
Term
Pelvis AKA
Definition
innominate
Term
All three parts of the pelvis intersect the
Definition
acetabular fossa
Term
Iliac Crest
Definition
long, superior edge of the ilium beginning with the ASIS and ending with the PSIS
Term
Anterior Superior Iliac Spine (ASIS)
Definition
located on the anterior, superior aspect of the ilium; origin for the sartorius; goniometry landmark for hip abduction & adduction
Term
Anterior Inferior Iliac Spine (AIIS)
Definition
located inferior to the ASIS; origin for the rectus femoris
Term
Posterior Superior Iliac Spine (PSIS)
Definition
located on the posterior, superior aspect of the ilium creating dimples in some patients; PSIS is in line with S2
Term
Posterior Inferior Iliac Spine (PIIS)
Definition
located inferior to the PSIS
Term
Greater Sciatic Notch
Definition
located between the PIIS and the ischial spine; contains the sciatic nerve
Term
Acetabulum
Definition
socket for articulation with femur; formed by ilium, ischium and pubis
Term
Ischial Tuberosity
Definition
referred to as “sits bones”; located at the most inferior aspect of the pelvis; origin for the hamstrings & adductor magnus
Term
Lesser Sciatic Notch
Definition
located between the ischial spine and the ischial tuberosity
Term
Ischial Spine
Definition
divides the greater sciatic notch from the lesser sciatic notch
Term
Ramus of the Ischium
Definition
bridges with the inferior ramus of the pubis to connect the pubic crest and the ischial tuberosity
Term
Obturator Foramen
Definition
large opening bordered by the superior ramus of the pubis, inferior ramus of the pubis, and ramus of the ischium; obturator nerve passes through the obturator foramen
Term
Acetabulum
Definition
socket for articulation with femur; formed by ilium, ischium and pubis
Term
Inferior Ramus of the Pubis
Definition
bridges with the ramus of the ischium to connect the pubic crest and the ischial tuberosity
Term
Superior Ramus of the Pubis
Definition
connects the pubic tubercle to the ilium
Term
Pubic Crest
Definition
anterior aspect of pubis adjoining the pubic symphysis
Term
Pubic Tubercles
Definition
small, horn-shaped; located on the superior aspect of the pubic crest; origin for the adductor longus muscle
Term
Obturator Foramen
Definition
large opening bordered by the superior ramus of the pubis, inferior ramus of the pubis, and ramus of the ischium; obturator nerve passes through the obturator foramen
Term
Acetabulum
Definition
socket for articulation with femur; formed by ilium, ischium and pubis
Term
Femoral Head
Definition
articulates with the acetabulum to form the hip joint
Term
Femoral Neck
Definition
located between the head and the trochanters
Term
Femoral Shaft
Definition
length of the femur
Term
Greater Trochanter
Definition
large, lateral projection between the femoral neck and the femoral shaft; insertion for the gluteus medius, gluteus minimus, and lateral rotators
Term
Lesser Trochanter
Definition
small, posterior projection inferior to the greater trochanter; insertion for the iliopsoas
Term
Intertrochanteric Line
Definition
connects the greater and lesser trochanters anteriorly
Term
Intertrochanteric Crest
Definition
connects the greater and lesser trochanters posteriorly; insertion for the quadrates femoris
Term
Pectineal Line
Definition
runs between the lesser trochanter and the linea aspera; insertion for the pectineus
Term
Linea Aspera
Definition
prominent longitudinal ridge along the posterior shaft of the femur; insertion for the adductor magnus, longus & brevis
Term
Adductor Tubercle
Definition
located proximal to medial epicondyle; insertion for the adductor magnus
Term
Medial Femoral Condyle
Definition
distal, medial femur; origin for the medial head of gastrocnemius
Term
Lateral Femoral Condyle
Definition
distal, lateral femur; origin for the lateral head of gastrocnemius
Term
Intercondylar Groove
Definition
depression between the medial and lateral condyles; articulates with the patella
Term
Medial Epicondyle
Definition
projection proximal to the medial condyle
Term
Lateral Epicondyle
Definition
projection proximal to the lateral condyle; origin for the popliteus
