Ankle fractures are breaks of the distal tibia or fibula (near or in the so-called malleolus) affecting the tibiotalar (ankle) joint. Occasionally, they involve the shaft of the fibula as well. Ankle fractures range from simple injuries of a single bone to complex ones involving multiple bones and ligaments.
Lt 1: Distinguish Between The Tibia and Fibula:
How to remember the difference between tibia and fibula:
Tibia is the thicker bone and always on the inside (medial) of your leg.
Fibula is the thinner(distal) bone always on the outside of your leg.
Lt 2:Identify The Major Bony Markings of The Tibia and Fibula:
Tibial Tuberosity- attachment for patellar tendon
Medial and Lateral Condyle- articulate with medial and lateral condyle of the femur
Lateral and Medial malleolus- outside and inside of ankle
Lt 3: Distinguish between tarsals, metatarsals, and phalanges of the foot and identify their location:
- Talus- think of ankle
-
- most superior
- joint with tibia and fibula
- Navicular-
-
- rectangular shape
- articulates with the talus
- medial side of the foot
- Calcaneus (heel bone)
-
- major load- bearing bone
- largest
- 3 cuneiform bones
-
- numbered 1-3 from medial to lateral side
- articulates with navicular bone and metatarsals
- Cuboid
-
- cube shaped
- lateral side
Lt 5: Understand the Numbering Of The Metatarsal Bones:
Metatarsal bones are numbered I-V (1-5) from medial to lateral.
The metatarsal I (1) would be the one connected to your big toe.
The metatarsal V (5) would be the one connected to your pinky toe
Lt 6: Understand The Anatomical Difference Between The Big Toe And Other Phalanges:
The big toe only is classified by two terms- proximal and distal
proximal is the part attached to the metatarsal bones
All other phalanges are classified by 3 terms- proximal, distal, and middle
middle is between the proximal part (the part attached to the metatarsal bone) and the distal part (the very tip of your toes)
Lt 7: Use Bony Markings To Determine Which Side Of The Body The Tibia And Foot Are From:
- use the tibia tuberosity to determine the anterior side of the tibia
- use the medial malleolus to determine the medial side of the tibia
- for your foot, use your big toe to determine the medial side
- for your foot, use your pinky toe to determine the lateral side
Lt 8: Understand How The Bones Create Articulations That Can Be Felt Or Seen In The Body:
Bones create articulations for connection with other bones. Articulations on the tibia and fibula that can be felt are your lateral malleolus and medial malleolus. These articulations can be felt around your ankle, they articulate with your tarsal bones of your feet.
Lt 9: Identify Specific Bony Landmarks That Can Be Felt and Seen, Regardless Of Being Covered By Muscle or Skin:
- your anterior crest can be seen and felt regardless of being covered by muscle and skin
-
- you can feel the anterior crest on the front (anterior) side of your leg, its that ridge in the middle of your leg
- your lateral malleolus and medial malleolus can be felt
-
- inside and outside of your ankle
Personal Artifacts:
On this quiz, I showed that I understood the bony markings of the tibia and fibula (Lt: 2). I also was able to distinguish which side of the body the bones came from and what view was shown, whether it was anterior or posterior. I missed half a point on this because I didn't include anterior clues for how I could tell that the bone came from the right side. I should have said that the anterior crest is always anterior or something like that.
On the back side of the quiz, I showed that I understood the difference between tarsals, metatarsals, and phalanges (Lt:3). I showed that I could name all the tarsal bones and identify them (Lt:4). I showed that I know the difference between the big toe and other phalanges (Lt:6).
Something that helped me understand so well about the tibia, fibula, and foot was making these note cards and studying them. I believe they are the reason why I did so well on both the quiz and the appendicular skeleton assessment.
Fibula, outer of two of the lower or hind limb, presumably so named ( fibula is Latin for “brooch”) because the inner, the, and the fibula together resemble an ancient brooch, or pin. In humans the head of the fibula is joined to the head of the tibia by and does not form part of the.
The base of the fibula forms the outer projection (malleolus) of the and is joined to the tibia and to one of the ankle bones, the talus. The tibia and fibula are further joined throughout their length by an interosseous membrane between the bones. The fibula is slim and roughly four-sided, and its shape varies with the strength of the attached muscles.
In many mammals, such as the and the rabbit, the fibula is fused for part of its length with the tibia.
