A punch biopsy is done with a circular blade ranging in size from 1 mm to 8 mm. The blade, which is attached to a pencil-like handle, is rotated down through the epidermis and dermis, and into the subcutaneous fat, producing a cylindrical core of tissue.

[9] When the pleural membranes are punctured, as occurs in penetrating trauma of the chest, air may travel from the lung to the muscles and subcutaneous tissue of the chest wall. [9]
Adhesions and fibrosis are made of dense fibrous tissue, which are strong and supportive, helping to prevent the injury or micro-injury from reoccurring. However, the fibrotic scar tissue causes the muscle tissue to become stuck together which restricts movement, causing pain, weakness, and limited joint mobility. [15] [16] [17] [18]
