patch graft การใช้

Some scientists suggest patch grafts ought to be applied to irreparable rotator cuff tears.
Therefore, a patch graft may not resolve the length change necessary to restore pennation angle; retraction of the torn tendon may lessen the post-tear pennation angle and restore muscle strength to a greater extent.
This may require preventive measures using antifibrotic medications, such as 5-fluorouracil or mitomycin-C ( during the procedure ), or other nonantifibrotic medication methods, such as collagen matrix implant, or biodegradable spacer, or later on create a necessity for revision surgery with the sole or combinative use of donor patch grafts or collagen matrix implant.
For example, erosion, where the conjunctiva erodes over the shunt leaving it exposed, the condition of which may be revised or prevented in advance by the use of amniotic membrane, donor patch grafts, The ologen collagen matrix facilitates tissue regeneration and its application over the site of device implantation can strengthen tissue recovery, reducing possibility of erosion.
