Abstract

The most marked changes in human muscle following tendinous injury can be observed in the contractile components. There is a widening of the Z-membrane, dispersion of the sarcomers, a break in their continuity, and detached bundles of myofibrils are found in the sarcoplasm. A change occurs also in the proportion of different muscle fibre types. In the muscle with tendinous injury a predominance of type II fibre becoming apparent. Among the proteins of myofibrils, a product of disintegration of a molecular weight of 31,000 can be demonstrated, and in some muscles products of disintegration with molecular weights between 90,000 and 58,000 arise.
