-The body of talus is almost entirely covered by articular cartilage.
- The medial malleolus articulates with the medial facet of the talus and
divide into an anterior colliculus and a posterior colliculus, which provides
attachment to superficial and deep deltoid ligaments respectively.
-The tibiotalar articulation is considered to be highly congruent such that 1
mm talar shift within the mortise decreases the contact area by 42 %.

INTRODUCTION
Ankle fractures are among the most common injuries and
management of these fractures depends upon careful
identification of the extent of bony injury as well as soft tissue
and ligamentous damage.
The key to successful outcome following ankle fractures is
anatomic restoration and healing of ankle mortise.

On the anteroposterior view:-
-The distal tibia and fibula, including
the medial and lateral malleoli, are
well demonstrated.
-Important note is that the fibular
(lateral) malleolus is longer than the
tibial (medial) malleolus.

-This anatomic feature, important for maintaining ankle stability, is crucial
for reconstruction of the fractured ankle joint.
-Even minimal displacement or shortening of the lateral malleolus allows
lateral talar shift to occur and may cause incongruity in the ankle joint,
possibly leading to posttraumatic arthritis.

Pott fracture:
In the Pott fracture, the fibula is
fractured above the intact distal
tibiofibular syndesmosis, the
deltoid ligament is ruptured, and
the talus is subluxed laterally.

Dupuytren fracture:
(A) This fracture usually
occurs 2 to 7 cm above
the distal tibiofibular
syndesmosis, with
disruption of the medial
collateral ligament and,
typically, tear of the
syndesmosis leading to
ankle instability.
(B) In the low variant,
the fracture occurs more
distally and the
tibiofibular ligament
remains intact.

Wagstaffe-LeFort
fracture:
In the Wagstaffe-LeFort
fracture,on the
anteroposterior view, the
medial portion of the fibula is
avulsed at the insertion of
the anterior tibiofibular
ligament. The ligament,
however, remains intact.

Tibial Pilon Fractures
The terms tibial plafond fracture, pilon fracture, and distal tibial
explosion fracture all have been used to describe intraarticular fractures
of the distal tibia.
Accounts for 7 to 10% of all tibia fractures.
Most common in men of 30-40 years.
These terms encompass a spectrum of skeletal injury ranging from
fractures caused by low-energy rotational forces to fractures caused by
high-energy axial compression forces arising from motor vehicle
accidents or falls from a height.

Source:Rosen
Rotational variants typically have a more favorable
prognosis, whereas high-energy fractures frequently are
associated with open wounds or severe, closed, soft-
tissue trauma.

-Because of their high energy nature, these fractures can be expected to
have specific associated injuries to calcaneum, tibial plateau, pelvis and
vertebral fractures.
-Swelling is often massive and rapid, required serial assessment of skin
integrity, necrosis and fracture blisters.
-Meticulous assessment of soft tissue damage is of paramount
importance.
-Some advise waiting 7 to 10 days for soft tissue healing to occur before
planning surgery.
