How It Works

Three simple steps to accurate fracture classification:

1. Select Fracture Location

Identify which malleoli are involved: medial, lateral, or posterior.

2. Answer Guided Questions

Our algorithm adapts to show only relevant questions based on your selections.

3. Get Classification

Receive detailed classifications with clinical notes and treatment considerations.

Classification Systems

Danis-Weber

Based on fibular fracture location relative to the syndesmosis.

Level	Type	Stability
Infrasyndesmal	A	Stable
Transsyndesmal	B	Variable
Suprasyndesmal	C	Unstable

Lauge-Hansen

Based on injury mechanism (foot position + deforming force).

Mechanism	Abbreviation	Stages
Supination-Adduction	SA	2
Supination-External Rotation	SER	4
Pronation-External Rotation	PER	4
Pronation-Abduction	PA	3

AO/OTA

International alphanumeric classification system for ankle fractures (44).

• 44-A: Infrasyndesmal (A1, A2, A3)
• 44-B: Transsyndesmal (B1, B2, B3)
• 44-C: Suprasyndesmal (C1, C2, C3)

Bartonicek

Posterior malleolus classification based on fragment size and location.
