Describe the features of the proximal fibula
|
- No weight-bearing function so the shaft can be used for bone grafts
- Lateral collateral ligament inserts into its head
- Common peroneal nerve wraps around the neck of the fibula to beomce superficial in the anterior compartment of the leg → commonly injured e.g. when hit by car

Describe the bones of the foot
|
- 7 tarsal bones = calcaneus, talus, navicular, cuboid, medial, intermediate and lateral cuneiforms
- Talus has a head, body and neck, articulates with the tibia at the trochlea (or body) of the talus, and articular processes either side articulate with the malleoli of the tibia and fibula
- Only the head of the talus can be seen from the inferior surface of the foot

How is the ischial tuberosity palpated?
|
- Gluteus maximus covers the ischial tuberosity so to palpate it, the hip must be flexed similar to sitting
- The ischial tuberosity can get sore if sit down for too long → Paddler's bottom

Describe the anatomy of the patella
|
- Sesamoid Bone
- Articulates with femoral condyles
- Usually has a smooth articular side which may become pathologically roughened (quandramalasia patella) and cause pain walking up and down stairs
- Quadriceps muscles pass over the patella into the tibial tuberosity
- Patella slides up and down in its groove and may dislocate laterally in juveniles if the medial quadratus is too weak to pull the patella correctly

Where do the bones of the hips come together and describe this in a juvenile
|
- Ilium, ischium and pubis meet together at the acetabulum
- In the juvenile these bones are separated by a tri-radiate cartilage which appears like a Mercedes sign
- The bones fuse around that ages of 20-25 years

- Bryant's triangle = ABC
- This is constructed with the patient supine as a rough means of detecting disturbance of the normal anatomy of the femoral head and neck
- Pathology of the femoral head or neck which displaces the greater trochanter (e.g. fracture) will tend to shorten BC

Briefly describe the pathology of Osgood-Schlatter's disease
|
- Pain over the tibia tuberosity with overuse of the quadriceps muscles during the growing phase
- Usually in young males
- Can get necrosis and avulsion of tendon

- Bryant's Triangle = ABC
- This is constructed with the patient supine as a rough means of detecting disturbance of the normal anatomy of the femoral head and neck
- The length of C is gauged on each side, and the sides compared. Pathology of the femoral head or neck which displaces the greater trochanter will tend to shorten the BC side
