The chest drain stitch and corner stitch are variations of the horizontal mattress. [citation needed] Other stitches or suturing techniques include: Purse-string suture, a continuous, circular inverting suture which is made to secure apposition of the edges of a surgical or traumatic wound. [13] [14] Figure-of-eight stitch; Subcuticular stitch ...
Adsorbable biological suture material. Chromic is an adsorbable suture made by twisting together strands of purified collagen taken from bovine intestines. Due to undergoing a ribbon stage chromicisation (treatment with chromic acid salts), the chromic offers roughly twice the stitch-holding time of plain catgut.
This treatment produces roughly twice the stitch-holding time of plain catgut, but greater tissue inflammation occurs. Full tensile strength is extended to 18–21 days. It is brown rather than straw-colored, and has improved smoothness due to the dry presentation of the thread (plain catgut is wet). It is otherwise similar to plain catgut. [3]
The vertical mattress stitch is most commonly used in anatomic locations which tend to invert, such as the posterior aspect of the neck, and sites of greater skin laxity such as the closure of lax skin after removing a dermoid cyst or reduced subcutaneous tissue (e.g., the shin) that do not provide adequate subcutaneous tissue for dermal closure.

Vicryl and other polyglycolic-acid sutures may also be treated for more rapid breakdown ("Vicryl Rapide") in rapidly healing tissues such as mucous membrane or impregnated with triclosan ("Vicryl Plus Antibacterial") to provide antimicrobial protection of the suture line. Because Vicryl is slow-absorbing and often braided, its use is ...
Many now pass the stitches through much smaller incisions to reduce wound healing time and limit the threat of infection and other complications. Superior suturing devices and techniques have also ...
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
An alternative to the surgical knot is a disposable clip that is placed at the end of the suture to keep stitches secure. A hemoclip is a titanium V-shaped clip with extensions that are squeezed together during application. The clips are available in various sizes and were originally designed to compress vessels for hemostasis. [5]
