| Summary: | Introduction: Os Peroneum is round or oval shaped sesamoid
within the substance of the Peroneus longus tendon as it plays
on the Cuboid bone.
Materials and Methods: Thirty six embalmed cadavers were
dissected bilaterally. Lateral part of foot and sole was dissected
to expose Peroneus longus tendon and Os Peroneum.
Measurements of Os Peroneum and articular surfaces of
cuboid (calcaneum) were taken by the Digital Vernier Caliper.
Histological and Radiological Examinations of Os Peroneum
were also done.
Observation: A flattened oval enlargement i.e. Os Peroneum
was found in all the tendons examined. The deep surface of
Os Peroneum (i.e. articular surface) was concave, smooth and
shiny; sometimes divided into two parts. There was a well
defined convex articular facet on the Cuboid at the proximal end
of the peroneal sulcus, which sometimes extended proximally
on to the Calcaneum forming a synovial joint.
Results: Average length of Os Peroneum was found to be 13.35
mm (Right - 13.35 mm, Left - 13.35 mm). Average breadth of
Os Peroneum was 8.96 mm (Right - 8.87 mm, Left - 9.05 mm).
Average thickness of Os Peroneum was 4.11 mm (Right - 4.13
mm, Left - 4.10 mm). Incidence of double articular facets on
cuboid and Calcaneum was more on the right side (25.80%)
than the left (16.20%).
Conclusion: Findings suggest that Os Peroneum is present at
the site of angulations of Peroneus Longus tendon with attendant
change in direction and the exposure to various stresses and
strains leading to its thickening and formation of Os Peroneum. |
