During reconstructive procedures performed 4-16 weeks after the tendon lesion the specimens obtained from the injured muscle have been examined by the authors. It was found that after the tendon injury inactivity atrophy develops and a condition of equilibrium could be observed at this time. The most important changes in the fine structure were seen in the contractile elements: these were atrophied, homogenized, fragmentated and ragged independently from the functional unities. The number of the mitochondria was considerably decreased, the sarcoplasmic reticulum was increased, and the difference between the originally red and white muscular fibres was indistinct. The glycogen content of the musculature was decreased, or it disappeared completely. No pathologic changes have been observed in the sarcolemma, the cell nuclei and the motor nerve end-organs.
