Avascular necrosis (AVN), also called osteonecrosis or bone infarction, is death of bone tissue due to interruption of the blood supply. [1] Early on, there may be no symptoms. [1] Gradually joint pain may develop, which may limit the person's ability to move. [1] Complications may include collapse of the bone or nearby joint surface. [1]
The major tissues affected are nerves and muscles, where irreversible damage starts to occur after 4–6 hours of cessation of blood supply. [4] Skeletal muscle, the major tissue affected, is still relatively resistant to infarction compared to the heart and brain because its ability to rely on anaerobic metabolism by glycogen stored in the cells may supply the muscle tissue long enough for ...

People with the condition usually present with a painless swelling in the area of the clavicles at 2 to 3 years of age. [9] Common features are:
The postmortem interval (PMI) is also called the time since death. It is the time lapse between death and discovery. After death, decomposition occurs. Decomposition includes physical, chemical, and biological changes. [19] Below are some of the biochemical changes that happen during decomposition which can help estimate the time since death ...
Physical therapy is often used before and after the operation to improve recovery time and outcomes. Potential complications include pneumothorax, infection, loss of sensation, motor problems, subclavian vessel damage, and, as in all surgeries, a very small risk of permanent serious injury or death.

Cadaveric spasm is seen in cases of drowning victims when grass, weeds, roots or other materials are clutched, and provides evidence of life at the time of entry into the water. Cadaveric spasm often crystallizes the last activity one did before death and is therefore significant in forensic investigations, e.g. holding onto a knife tightly. [4]
