Lecture 2: Hip, Knee Complex And Ankle Joint Flashcards
A structure projecting in the posterior ischium which intervenes the greater and lesser sciatic notches.
Ischial spine
It is where hamstring muscles originate.
Ischial tuberosity
Obturator foramen is filled by —— membrane
Obturator membrane
Maximum contact or closed packed position of the hip joint
Flexion
Slight external rotation
Slight abduction
Inferior deficient margin of acetabulum
Acetabular notch
Articular surface of acetabulum
Lunate surface
Angle of torsion in hip joint.
12-15 degrees
Angle of inclination of hip joint
126 degrees
A ligament contained inside the acetabular fossa
Ligamentum teres
Tension in ligamentum teres occurs during:
Add+flexion+external rotation
Add+ext+internal rotation
Small depression in the head o femur
Fovea capitis
Normal orientation of femur neck
Downward, backward, laterally
Extends SUPERIORLY from the shaft and lateral to the region where the shaft joins the neck and femur
Greater trochanter
It is where quadrate tubercle is found
Intertrochanteric crest
Angle created by shaft along the vertical axis from lateral to medial
7 degrees
It is where muscles and intermuscular septa are attached.
Linea aspera
Linea aspera diverge superiorly into ——- in superior medial direction, and ——— in superior lateral direction.
Pectineal
Gluteal tuberosity
Linea aspera diverge inferiorly into —— and ——-
Medial supracondylar ridge and lateral supracondylar ridge
A flat triangular surface on the posterior inferior shaft.
Popliteal surface
Lateral and medial condyles are separated posteriorly by ——.
Intercondylar notch
——- tubercle found in the medial epicondyle. It is where adductor muscles insert.
Adductor tubercle in the medial epicondyle
The cavity of the acetabulum is deepened by ——-
Acetabular labrum
Ligament that bridges that acetabular notch
Transverse acetabular ligament
Nerve supply in the hip joint
Sciatic, obturator, femoral, nerve to quadratus femoris
3 Ligaments of the hip joint
Ischiofemoral
Pubofemoral
Iliofemoral
Strong inverted y-shaped ligament of bigelow.
Attached to AIIS
Insert to trochanteric line
Iliofemoral ligament
Action of iliofemoral ligament
limits overextension
Action of pubofemoral ligament
Limits both extension and ABDUCTION
Action of ischiofemoral ligament (a spiral shaped ligament)
Limits extension
What are the movements possible in the hip joint?
Flex, extend, abd, add, lateral and medial rotation, circumduction
Flexor muscles of the hip joint
Iliopsoas
Rectus femoris
Sartorius
Pectineus
Extensor muscles of the hip joint
Gluteus maximus and hamstring muscles (except the short head of biceps femoris)
ROM of extension and flexion at hip joint
Ext: 0-10 degrees
Flex: 120 degrees (if knee is flexed) and 70-90 degrees if knee is extended
Limitation of flexion when knee joint is extended is due to tension in the hamstring muscles.
