| Summary: | Introduction: Os Vesalianum (OSV) is an accessory ossicle
of the foot, first described by Andreas Vesalius, during 1543
in “de humani corporis fabrica”. It is located proximal to the
base of the fifth metatarsal bone within the peroneus brevis
tendon, rarely symptomatic, detected incidentally on routine
radiographs, with an incidence of 0.1% to 5.9%. OSV has
rarely been implicated as a causative factor for lateral foot
pain, peroneus brevis tendonitis and is commonly been
misdiagnosed on routine radiographic examination as
fracture of fifth metatarsal bone, due to the lack of knowledge
pertaining to it.
Aim: To study the presence, incidence, location and morphology
of OSV.
Materials and Methods: Retrospectively, 1000 radiographs
both anteroposterior and oblique view of the foot was observed
for the presence, incidence, location and morphology of OSV.
Statistical analysis was done by descriptive statistics.
Results: In the present study, we observed an incidence of
1.5% of OSV, with predominantly round or ovoid shaped. OSV
was more common in males than females in the present study,
which was more often located on the posterolateral aspect of
the base of fifth metatarsal and lateral to cuboid bone.
Conclusion: Orthopaedician and radiologists must be aware of
such bony variants in the foot and ankle, which can serve as
radiological pitfalls that can cause confusion leading to wrong
diagnosis and delayed management in cases presenting with
history of trauma and lateral foot pain. |
