5. Regarding forearm fractures

A Bartons fracture involves the distal radio-ulnar joint

B Galeazzi fractures require fixation of the related joint disruption in most cases as well as ORIF of the bone fracture

C Monteggia fracture requires POP application in supination

D Monteggia fracture dislocation involves fracture of the radius proximally and distal radio-ulnar joint disruption

9. Which of the following is TRUE with regards to knee injuries?

A Usually a varus force with axial loading will produce a lateral condylar fracture of the tibia

B Elderly patients with a lateral tibial plateau fracture usually require a bone scan as part of their investigation

C A Segond fracture is a marker of collateral ligament injury and ACL disruption

D Popliteal artery is relatively protected from injury due to it’s anatomical position

Look at the given X- Ray and identify the injury. Which of the following statement is incorrect about this injury?

More than 75% are associated with a tear of the ACL.

Usually results from abnormal varus stress to the knee, combined with internal rotation of the tibia.

Plain Anterio-posterior X Ray is the gold standard investigation.

The X-Ray show Segoid Fracture
