The histochemical structure of the deep fascia and its structural responseto surgery

The histochemical structure of the deep fascia and its interface with the u nderlying muscle was examined in ten pigs, This structure was also evaluate d after it had been raised as a fascial flap and in another site after the underlying muscle surface had been disrupted, The deep fascial is a simple structure of densely-packed collagen bundles and elastin fibres, and has hy aluronic acid concentrated on its inner surface, which is in contact with t he underlying muscle, There is no specialised lining of this surface of the fascia to account For its gliding properties. The post-surgical specimens demonstrated preservation of the structure of the interface between fascia and muscle, including the retention of the hyaluronic acid lining, if the e pimysium was intact. However, if the epimysium was disrupted, the structure of the interface was obliterated.
