Bony Lower Extremity Flashcards
Weight transfer
- Weight of the upper body is transmitted centrally through the vertebral column
- Divided, and directed laterally by means of the bony arch that is formed by the sacrum and the ilium on each side. The dense bony column for weight transmission through the head of the femur.
- head of the femur to the shaft
- Pubic rami form braces that help maintain the integrity of the arch.
Tubercle on iliac crest
For the division of the extensor gluteal muscles and abductor gluteal muscles
Anterior superior iliac spine
Attachment of sartorius
Inferior gluteal line
Attachments for gluteus minimus and medius
Anterior inferior iliac spine
Attachment for rectus femoris
Acetabulum parts
Articular lunate surface
Acetabular fossa
Pubis parts
Pubic crest
Pubic tubercle
Acetabular notch
Spanned by transverse acetabular ligament, which will allow for the acetabular labrum to be secured
Ischiopubic ramus
Inferior ramus of pubis
Ramus of ischium
Ischial tuberosity
Attachment for the hamstring muscles
Ischial spine
Attachment for the sacrospinous ligament
Body of illium
Forms shelf of the acetabulum for weight-bearing
Fault in the articular cartilage of the femoral head
Called the fovea Capitis
For the attachment of the ligamentum teres major
Intertrochanteric line side of femur
Anterior surface
Which muscle attaches most superiorly on the greater trochanter
Piriformis
Pectineal line on which side of the femur
Posterior
Spiral fracture on this line
Attachment site for the gluteus medius
More posteriorly on the greater trochanter
Intertrochanteric line side
On the anterior side of the femur
Intertrochanteric crest side
On the posterior side of the femur
Gluteal, tuberosity side
Posterior side of the femur
Linea aspera side
Posterior side
Gluteus medius placement on a femur
Posteriorly placed
Gluteus minimus Placement on femur.
Anteriorly placed
Adductor tubercle attachment
Attachment of the hamstring portion of the adductor Magnus to help form the adductor hiatus
In a cross-section for the femur, which side is more pointed?
The posterior side- has linea aspera and allows attachment of the quadriceps muscles and the medial compartment and posterior compartment muscles
deep fascia will attach to both medial and lateral aspect of the linea aspera
Flat anterior surface
It is flat anteriorly to allow the attachment of the quadriceps muscles
Lateral medial sides are rounded
Angle of inclination
Between the long axis of the femoral neck, and then the femoral shaft
Varies with age, sex and development
Coxa Vara
Angle of inclination is decreased
The shaft or the femur deviates towards the midline
Mild shortening of the lower limb
Limits passive abduction of the hip
Coxa valga
Increased angle of inclination
Shaft of the femur moves away from the midline
Lengthening of the lower limb
Limits passive adduction of the hip
The tibia has the site of attachment for which muscles on anterior side
Pes anserine ligament
Sartorius gracilis, and semitendinosis muscles
Cross-section of the tibia shows
Sharp edge on the anterior side
Flattened lateral surface
flattened medial surface And a rounded medial border
Rounded and flat posterior side
Soleul line side of tibia
Posterior side
Tibial tuberosity on which side of tibia
Anterior side
Fibula cross-section
Pointed anteriorly
Rounded posteriorly
Rounded laterally
Articular facet of the patella
Medial is smaller
lateral is bigger
condyles of femur compared
Lateral condyle - Anterior surface is taller
Patellar almost always dislocate laterally
