Ankle Injuries Dr Peter Brukner, OAM Sports Physician Associate Professor Centre for Sports Medicine Research & Education The University of Melbourne Adjunct Professor School of Human Movement Studies The University of Queensland Ankle Sprain The most likely diagnosis is lateral ligament sprain Range of Motion Dorsiflexion Plantarflexion Inversion 1
Lunge Palpation Palpation (Medial) 2
Palpation Anterior Drawer Talar Tilt 3
Proprioception Ankle Sprain The majority of these injuries respond well to a standard treatment regime Ankle Sprains R.I.C.E NWB/PWB/FWB electrotherapeutic modalities strengthening proprioception tape/brace 4

The Difficult Ankle A significant group do not progress The Difficult Ankle. and complain of persistent pain, swelling and impaired function after 3-6 weeks Principles of Diagnosis 1. 2. History 3. Examination 4. Investigation 7
1. Common 2. Less common 3. Not to be missed 1. Common chronic instability synovitis ankle joint sinus tarsi syndrome posterior impingement anterior impingement 1. Common talar dome base of 5th metatarsal chronic instability synovitis ankle joint sinus tarsi syndrome posterior impingement anterior impingement 8

Principles of Diagnosits 1.Possible causes 2. History 3. Examination 4. Investigation 18
History mechanism of injury pain, swelling, bruising level of dysfunction early management? X-ray History subsequent progress current symptoms pain swelling impingement instability function history of previous injury Principles of Diagnosits 1.Possible causes 2. History 3. Examination 4.

Examination inspection range of motion palpation ligament testing functional testing Examination strength testing proprioception neural tension impingement tests anterior posterior Principles of Diagnosits 1.Possible causes 2. History 3. Examination 4. Investigation 20
Plain X-ray 1. fracture 2. posterior impingement 3. anterior impingement } Special views Triple Phase Bone Scan important screening testing three phases angiogram (immediate) blood pool (2 minutes) bone phase (2-3 hours) 21
Triple phase bone scan no uptake uptake uptake Uptake - talar dome fracture - other fracture Mild Uptake - impingement syndrome - synovitis - RSD (late) 22
No Uptake impingement syndrome AITFL injury synovitis sinus tarsi syndrome dislocating peroneal tendon RSD (early) CT scans If bone scan shows uptake CT performed to visualise fracture MRI alternative to CT more sensitive in osteochondral damage soft tissue imaging 23
The Difficult Ankle Investigation Conclusion consider possible causes good history thorough examination investigate bone scan/mri is the key 24
