There are some contra-indications to suturing with certain materials or in general, for example: It might be a bad idea to suture up wounds which are ​ (a)   , such as bite wounds. It might also be contraindicated in ​ (b)   where there is not enough skin to create appropriate joining. We must also consider ​ (c)   such as the alar fold which will not join well and the chance of (d)   , especially when using materials such as​ (e)   .

• already infected
• avulsions
• concave surfaces
• inflammatory reactions

• Straight

• Tends to be used for deeper tissues such as gastrointestinal, respiratory and urological procedures.

• 1/2 circle

• Tends to be used for ophthalmic and microsurgical procedures
