Ottawa Ankle Rules:

Point tenderness in either malleolar zone, mid-foot zone, base of fifth metatarsal, or at navicular

2

Advanced imaging used after radiographic findings are either

(1) Insufficient to guide treatment or
(2) After radiographic findings are negative when further injury is suspected

3

Inversion stress accounts for what percentage of all traumatic conditions of the ankle?

85%

4

What is degree of damage dependent on?

direction and magnitude of applied force

5

Sprains due to inversion stresses damage

lateral collateral ligaments
Anterior talofibular and calcaneofibular ligaments most frequently injured components of LCL system

6

Sprains due to eversion stresses damage:

medial collateral ligament

7

Common injuries at ankle:

Fractures and fracture–dislocations

8

MOI of ankle:

axial or rotational loading

9

Unimalleolar fracture

indicating fracture of either lateral or medial malleolus

10

Bimalleolar fracture

indicating fracture of both lateral and medial malleoli

11

Trimalleolar fracture

fracture of both malleoli and posterior rim of tibia…..sometimes called “third malleolus”

12

Other fractures involving ankle joint include

Shaft fractures of fibula and tibia
Comminuted fractures of distal tibia
Intra-articular fractures of tibial plafond or talar dome

13

Most common complications of ankle fractures:

non-union and degenerative joint changes associated with post-traumatic arthritis

14
