5.9 E) Xi) Orthopaedics Fractures Tibial Plateau Fractures

Front 1

Classification of tibial plateau fractures?

Back 1

1. Vertically orientated {split}
2. Locally compressed
3. Combined split-compression

Front 2

Which part of the tibial plateau is the

most common area for fractures?

Back 2

Lateral tibial plateau 85%

Front 3

Which is incorrect regarding tibial plateau

fractures?
1. Most of the body's weight is borne on the medial side of the knee,

giving the medial tibial plateau increased trabecular density.
2. Tibial plateau fractures are missed 16% of the time.
3. Tibial fractures are the second most common fractures about the knee [ 32% ]{behind patellar fractures}.
4. The medial tibial plateau is involved in 85-90 cases of tibial plateau fracture

Back 3

4. Lateral tibial plateau 85-90%

Front 4

Which is incorrect regarding tibial plateau

fractures [TPF]?
1. Impact to the lateral femoral condyle [ "bumper injury"] causes 25-50% of TPF
2. Osteoporosis is a major risk factor for TPF
3. Axial compression fractures [ fall from height] are responsible for less cases of TPF than bumper injuries.
4. Depression of a TPF greater than 8mm is usually treated with surgical elevation.
5. the 2 factors important for the treatment of TPF are "depth of

depression" and associated ligamentous/meniscal injury.

Back 4

3. Axial compression fractures are

responsible for most other TPF.

Front 5

Which is incorrect, regarding Tibial plateau fractures?

1. In trauma, a standard lateral view of the knee is preferred.
2. Increased trabecular density of the lateral tibial plateau in trauma

usually indicates a compression fracture
3. Lateral displacement of the tibial plateau relative to the femoral condyle, can occur with plateau fractures.
4. A lipohaemarthrosis appears on the cross-table lateral radiograph of the knee
5. A depth of depression of > 8mm with tibial plateau fractures is an

indication for Surgical repair / elevation.
