|
Term
|
Definition
| traumatic spondylolisthesis with fracture through the pedicles or lamina of C2 secondary to a distraction-extension force. |
|
|
Term
|
Definition
| posterolateral defect of the humerus caused by anterior shoulder dislocation and "implosion" fx |
|
|
Term
|
Definition
| an impaction fracture of the superior iliac wing |
|
|
Term
|
Definition
| a burst fx of the ring of the atlas, with fx both anterior and posterior to the facet joints. It is secondary to an axial load on top of the head. There are usually four breaks in the ring and lateral spread of the lateral masses. |
|
|
Term
|
Definition
| fx of the base of the 5th metatarsal |
|
|
Term
|
Definition

|
|
Term
|
Definition
| avulsion fx of the fibular attachment of the anterior tibiofibular ligament |
|
|
Term
|
Definition
| fracture-dislocation through the tarsometatarsal joints, commonly associated with disruption of the second tarsometatarsal joint and alteral dislocation of the second thru 5th tarsometatarsal joints. |
|
|
Term
|
Definition
| avulsion of the medial epicondyle of the elbow secondary to valgus stress |
|
|
Term
|
Definition
| fx of the proximal third of the fibula with tear of the distal tibiofibular syndesmosis and the interosseous membrane. May also have fracture of the medial malleolus or tear of the deltoid ligement |

|
|
Term
