After selective resection of the nerve leading to the medial head of the gastrocnemius muscle for surgical repair of the calf's appearance, unpredictable changes in appearance often occur. Dr. Lee CJ and colleagues at Inha University School of Medicine in Incheon, South Korea, recently encountered a rather rare case. The nerve leading to the medial head of the gastrocnemius muscle on one side was selectively transected, but the nerve leading to the soleus muscle on the other side was also accidentally severed. In order to study the reasons for the change in appearance, researchers should

use MRI to compare the posterior chamber muscle volume

ratios of 8 normal calves of 8 normal volunteers and the calves of both sides of the reported cases. . The results showed that the volume ratio of the medial head, lateral head and soleus muscle of the calf calf muscle in the normal control was 0.22:0.12:0.66. The corresponding volume ratio of the calf with atrophy of the medial head of gastrocnemius is 0.13:0.20:0.67. The corresponding volume ratio of the calf with fish muscle atrophy is 0.27:0.14:0.59. Dr. Lee and others concluded that both physicians and patients should understand before surgery that even if a muscle in the gastrocnemius group of the calf undergoes selective atrophy after selective neurectomy, Other muscles may undergo compensatory hypertrophy, which may affect the appearance of the calf
