What is Grade 4 cirrhosis?
Stage 4: Liver failure

What is a Stage 4 muscle tear?
As described by Pollock et al.,38 Grades 1–3 injuries reflect small, moderate, or extensive “tears” respectively to the muscle tissue, as primarily determined by the extent of edema and tissue disruption, but also by the tissue involved. Grade 4 injuries are considered complete tears to either the muscle or the tendon.
What is a high grade injury?
In higher-grade injuries, bleeding from broken blood vessels increases the degree of swelling. Injuries to soft tissues such as ligaments, muscles and tendons can come on suddenly, and occasionally be recurrent or get worse over time (usually due to suboptimal treatment and rehabilitation).
How serious is a grade 4 liver laceration?

What is a Type 4 muscle injury?
A type 4 lesion is a sub-total tear with more than 50% of breakage surface or a complete tear of the muscle, involving the muscle belly or the musculotendinous junction. Our classification of structural injuries defines also the site of the lesions in terms of proximal (P), middle (M), and distal (D).
Do anti-inflammatories help heal pulled muscles?
By taking anti-inflammatories for an injured muscle, you inhibit the inflammation and therefore the process of getting rid of the damaged cells. This has a knock-on effect on the formation of new cells to rebuild the injured part of the muscle, and so the whole healing process is compromised.
What are the grades of injury?
Grade I (Mild): Tissue is stretched. Grade II (Moderate): Involves stretching and some tearing of tissue. Grade III (Severe): Complete tearing of tissue.
