In this video, we demonstrate suturing techniques — core suture and Q suture — to repair the foot flexor tendon in an ex vivo porcine model. Q sutures enhance the strength of the core suture in tendon repair and decrease gapping at the tendon repair site.

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures. Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

FAQs
Tension determines how closely wound margins remain aligned during healing. Appropriate tension supports stable apposition, whereas excessive tension can impair blood flow at the tissue edges and contribute to excessive scarring. Consequently, tension must be balanced with the condition and type of tissue so the closure supports repair without compromising the biological environment needed for recovery.
Tissue type and wound condition influence how the margins respond to support during repair. A closure that is suitable for one tissue or wound may not provide the same outcome in another. These variables therefore guide decisions about suture material and placement, while also helping researchers interpret differences in healing, tissue regeneration, or complications.
Closure does not complete healing by itself; it supports the wound while biological repair proceeds. Inflammation occurs first, followed by tissue formation and remodeling. Maintaining apposition and limiting movement gives these stages a more controlled setting, allowing investigators to examine how physical support interacts with the progression of tissue repair over time.
Planning should account for the tissue type, wound condition, suture material, placement, and expected postoperative care. The thread must be sterile, and the margins should be supported with appropriate tension. Considering these factors together helps maintain anatomical continuity while reducing the likelihood that mechanical support will interfere with blood flow or produce excessive scarring.
Suture closure provides a controlled experimental model for examining tissue regeneration and wound healing. Researchers can also use it to investigate infection and evaluate biomaterial performance. Because tissue type, wound condition, material, placement, and postoperative care can be considered as variables, the approach supports comparisons of how different conditions influence repair outcomes.
Assessment can focus on whether tissue edges remain appropriately supported and whether repair progresses through inflammation, tissue formation, and remodeling. Studies may also examine tissue regeneration, wound-healing behavior, infection, scarring, and the performance of the suture material. Interpreting these outcomes requires considering the wound and tissue conditions as well as postoperative care.
