Necrotic muscle fibers are swollen and eosinophilic and lack striations and nuclei. Small-vessel walls are thickened and hyalinized , with luminal narrowing or complete occlusion. Biopsy cultures for bacteria , fungi , acid-fast bacilli and stains are negative in simple myonecrosis.
Nerve injury occurs in about 15.3% of knee dislocations, while major artery injury occurs in 7.8% of knee dislocations. [35] More than half (53.5%) of knee dislocations have an associated torn meniscus. [35] Tendon rupture occurs up to 13.1% of the time. [35] Elbow. The incidence rate of elbow dislocations is 5 to 6 per 100,000 persons per year ...
