Q Suture Technique: A Suturing Technique to Reduce Gap Formation and Increase Tensile Strength in Tendon Repair
0 Views •
2025
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...

Source: Sharon Bord, MD, Department of Emergency Medicine, The Johns Hopkins University School of Medicine, Maryland, USA Placement of an intravenous (IV) catheter is one of the key procedures in medicine. The IV catheter allows patients to receive critical medications, including pain medicine, insulin, antibiotics, blood products, and fluids for rehydration. Additionally, placing an IV catheter allows for blood samples to be obtained, which can be sent to the laboratory for testing and...

Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT The purpose of peripheral intravenous catheter (PIV) insertion is to infuse medications, perform intravenous (IV) fluid therapy, or inject radioactive tracers for special examination procedures. Placing a PIV is an invasive procedure and requires the use of an aseptic, no-touch technique. Common IV venipuncture sites are the arms and hands in adults and the feet in children. According to...
FAQs
Peripheral suture placement helps control mechanical forces at the wound margin by distributing tension across opposing peripheral tissue rather than allowing an individual stitch to bear the entire load. Maintaining that balance supports edge alignment while healing progresses and can limit wound separation. The result depends on matching placement, spacing, depth, and tension to the tissue and closure requirements.
Spacing and depth influence how evenly the wound edges are supported and how much tissue each stitch engages. Excessive tension can increase tissue trauma, whereas inadequate control may allow separation. For this reason, peripheral suture planning treats spacing, depth, and tension as related variables, not isolated choices, with the goal of stable approximation and less disruption.
Closing peripheral tissues securely can reduce residual gaps beneath or between approximated tissue layers, described as dead space. Limiting these spaces supports contact and stability as biological repair proceeds. This consideration is especially relevant when the technique is applied beyond routine skin closure, because deeper tissue procedures may require additional attention to tissue control and alignment.
The method may be used for skin closure or in selected procedures involving deeper tissues, but the closure goal remains consistent: secure edge control without unnecessary tissue trauma. Tissue location affects suture selection, depth, spacing, and tension. These variables must therefore be considered in relation to whether the priority is surface alignment, deeper stability, or both.
Before placement, clinicians consider the wound or incision, the tissue involved, and the level of support needed to maintain alignment. They then select suitable suture material and plan stitch depth, spacing, and tension. This coordinated assessment helps distribute forces, limit separation, reduce tissue trauma, and support either functional healing or a satisfactory cosmetic result.
Peripheral sutures are used most directly for skin closure and may also be chosen in selected procedures involving deeper tissues. Their broader application is edge control: maintaining alignment while the repaired area gains biological strength. Their value therefore extends beyond simply closing an incision, particularly when stability, reduced dead space, and preservation of function or appearance matter.
Outcomes can be judged by whether tissue edges remain aligned, tension is appropriately controlled, and the wound stays supported during healing. Additional considerations include tissue trauma, residual dead space, and the eventual functional or cosmetic result. These measures connect the technical choices of material, spacing, depth, and tension with the quality and stability of repair.
