[10] Hard tissue injuries to teeth and bones can occur with contusions, such as Battle sign, which indicates basilar skull fracture, and so-called raccoon eyes, which indicate midface fractures ...
Single or multiple z-plasties can be used. Specific modifications include the double-opposing z-plasty (sometimes called a "jumping man" flap) which can be useful for release of webbing of the medial canthus or release of 1st web space contractures.

Within the bone itself, the haversian canals become blocked with scar tissue, and the bone becomes surrounded by thickened periosteum.

[1] Like keloids, they form most often at the sites of pimples, body piercings, cuts and burns. They often contain nerves and blood vessels.
The sciatic nerve is highly mobile during hip and leg movements. [32] [33] Any pathology which restricts normal movement of the sciatic nerve can put abnormal pressure, strain, or tension on the nerve in certain positions or during normal movements. For example, the presence of scar tissue around a nerve can cause traction neuropathy. [34]
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]
