Evaluation of the results of sonographic study of ischemized extremity muscles in patients with the concequences of the compartment syndrome
We analyzed the results of sonographic study of 653 muscles in 69 patients with ischemic contracture (IC) in reactive–restoration period. Special computer programs evaluating tissue necrosis and δ–enthropy were elaborated in order to perform quantitative assessment of the muscle status. Increased necrotic part in the ischemized muscles correlated with the IC severity. Indicators of vertical δ–enthropy of ischemized muscles were significantly lower than in the intact muscles in severe and middle IC. Horizontal δ–enthropy indicators in the ischemized muscles, on the contrary, were significantly higher than in the intact muscles. We established significant positive connection between the severity of IC and the part of muscle necrosis. Using the regression analysis we established reverse correlation between the part of necrosis and δ–enthropy indicators, especially in the ischemized muscles. Low indicators of δ–enthropy (both vertical and horizontal) are the evidence of significant necrosis of the ischemized muscles, which has essential diagnostic significance.
