Overview
- What this deck covers
- Why the talus matters
- Talus fractures by the numbers
The Talus and Its Blood Supply
The anatomy that makes these fractures so difficult
- How the talus is built
- Overall shape of the talus from four views
- The talus as the keystone of the foot's arch
- The load-bearing top surface
- Inclination angles of the talar neck and body
- Why the blood supply is the key problem
- How the pieces get their blood
- Vascular supply of the talus — coronal sections
- Vascular supply of the talus — sagittal sections
- Structures to protect during surgery
- Neurovascular anatomy on the talar surface
Injury Mechanism and Classification
How talar neck fractures happen and how we name them
- The basic mechanism
- Collision of talus and tibia during dorsiflexion
- As the force continues: types II and III
- Dislocation of the subtalar joint
- The body of the talus slipping out of the joint
- Trapped body, and low-energy variants
Classification of Talus Fractures
Hawkins for neck fractures, Sneppen for body fractures, plus AO/OTA
- The Hawkins classification for neck fractures
- Type I talar neck fracture (undisplaced)
- Type II talar neck fracture (subtalar dislocation)
- Type III talar neck fracture (two joints dislocated)
- Type IV talar neck fracture (three joints dislocated)
- Hawkins grades and necrosis risk
- Reading Hawkins carefully
- Sneppen classification for talar BODY fractures
- AO/OTA classification — skeleton diagram
- AO/OTA classification — detail drawing
Assessment and Surgical Treatment
From first examination to fixation and complications
- Clinical assessment: history and soft tissue
- Watch the limb, and hunt for other injuries
- Imaging: X-rays
- Foot position for the Canale and Kelly talar-neck view
- Imaging: CT and vessels
- 3D CT reconstruction of a talus fracture
- When and when not to operate
- Timing of surgery
Open Reduction & Fixation
Positioning, approaches and fixation
- Setup and preparation
- The two main surgical approaches
- Medial approach to the talus
- Lateral approach to the talus
- Reducing the dislocation, then the fragments
- Fixing the fracture and after-care
Percutaneous Route & Outcomes
A less-invasive option, and the problems to expect
- Closed reduction and percutaneous fixation
- The percutaneous reduction, step by step
- Percutaneous screw fixation of a talar neck fracture
- After percutaneous fixation
- Comparison of talus fracture fixation methods
- Complications: soft tissue and healing failures
- Complications: malunion, necrosis and arthritis
- Three things to remember
