Healing of a muscle trauma. Correlation of sonographical and histological findings in an experimental study in rats
M. Lehto and A. Alanen
Healing of a partially ruptured gastrocnemius muscle was studied in rats
with sonographical and histological techniques. Ultrasonography was
performed 1-21 days after injury using a 7.5-MHz linear scanner. Following
ultrasonography, the injured muscles were examined histologically. The
injured area and development of hematoma were visualized during the first 5
days after trauma with ultrasonographical and histological observations.
Later, disorganization of regenerating muscle fibers appeared
sonographically more clearly than the scar tissue area demonstrated
histologically. The present study points out the accuracy of
ultrasonography in the examination of a muscle trauma, especially during
the early phases of healing.
