INTRODUCTION
Fractures of the talus are rare injuries with an estimated
prevalence of 0.008% of all childhood fractures
compared with 0.3% in adults.

As the paediatric foot is
flexible and its skeletally immature bones are less brittle,
they have higher elastic resistance than adult bone. Thus
the talus of a child can sustain higher force before it
fractures. The fracture of neck of talus is a more common
fracture site than talar body. Immobilisation by applying
cast is the treatment of choice for non-displaced fractures
but surgery is needed for displaced fractures of the talus
to lower the risk of complications such as avascular
necrosis etc.
CASE REPORT
A 9 year old boy was brought to the emergency
department with a history of fall from stairs of a height
between 4 to 5 feet, while playing. On physical
examination there was bruising over medial aspect of left
ankle. Swelling was present over the left ankle but there
was no evident deformity. He was unable to bear weight
on his left foot. There was tenderness and crepitus on
palpation and movements of the left ankle joint were
painful and restricted. Peripheral pulses were palpable
and there was no evident distal neurovascular deficit.
Patient underwent x rays of left foot. Radiological
findings were suggestive of fracture neck talus left foot as
shown in figure (a). Below knee slab was applied and
patient was prepared for surgery.
Surgery: Patient underwent closed reduction and internal
fixation with K wire. Post op ankle and foot radiographs
showed fixation of fracture neck talus done with closed
pinning using 3 K wires as shown in figures (b).
Prognosis: A child's bones heal faster than an adult's
because a thicker, stronger, and more active dense fibrous
membrane (periosteum) covers the surface of their bones.
ABSTRACT
Talus fracture is a rare injury in a paediatric patient. Among talus fractures, the fracture of neck of talus is more
common than fracture of body of talus. This can occur because of axial loading of the talus in a dorsiflexed foot
against the anterior tibia. Children’s bones are skeletally immature and hence less brittle. They have higher elastic
resistance than adult bone and are less likely to fracture. However talus fractures can still occur in paediatric patients
when there is history of high-energy trauma. It needs surgery and can be associated with complications like avascular
necrosis, delayed union, neuropraxia and may need a revision surgery. Here we present an unusual case of a talar neck
fracture in a young boy, which was a closed fracture without distal neurovascular deficit. Closed reduction and
internal fixation was done with K wire and post op X-rays and follow up X-rays showed complete union. Patient has
normal joint mobility and strength after a period of 1 year follow up.
