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
0 Views •
2025
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...

Iris Fixation via External Pentagram Suturing

The present protocol describes how a 10-0 polypropylene suture crosses the anterior surface of the iris, forming a pentagram to prevent both iris and pupil from moving toward the cornea. This can be combined with subsequent keratoplasty to cure bullous keratopathy with extensive anterior synechia of the iris.

Surgical induction of ischemic brain damage in the rat is a widely used model for stroke research. Here we demonstrate the induction of focal cerebral ischemia by occlusion of the middle cerebral artery. Visualization of the resulting infarct by histological staining and magnetic resonance imaging is also shown.
FAQs
Controlled traction stabilizes tissue or organ edges without requiring continuous manual holding. By maintaining alignment, the suture can improve exposure of the operative area and limit unwanted movement during dissection, repair, or manipulation. The amount of traction matters because it should support access while avoiding excessive pulling that could distort the tissue or interfere with the intended procedure.
Placement determines whether the stitch can maintain alignment and provide useful traction without causing unnecessary tissue disturbance. Selected tissue should support the intended positioning of an edge, incision, or organ during the procedure. In biological and biomedical work, careful placement helps preserve the target anatomy and can reduce trauma or distortion that might affect the manipulation or repair.
Stay sutures primarily provide temporary stabilization and positioning while another repair or manipulation is performed. They support access and control rather than serving as the principal closure or reconstruction. Separating these functions allows the operator to maintain a stable field during the procedure while carrying out the main repair with greater control and more consistent tissue alignment.
Tension determines how firmly the tissue remains positioned and how much traction is transmitted to it. Gentle, controlled tension can limit movement and improve exposure, whereas excessive tension may distort tissue or increase trauma. Consistent tension is therefore important in experimental surgery because it supports comparable handling conditions and can improve the reproducibility of observations.
The method begins by selecting the tissue, organ edge, or incision that requires stabilization. A suture is then passed through the chosen tissue and secured, after which gentle traction maintains the desired position. With the area stabilized, the operator performs the planned dissection, closure, specimen handling, or other manipulation while monitoring alignment and avoiding excessive tension.
Researchers may use stay sutures during tissue dissection, wound closure, specimen handling, and experimental surgery. These settings benefit from controlled positioning because tissue movement can make manipulation more difficult or reduce consistency between procedures. By supporting access and alignment, the technique can help investigators perform the intended intervention and document outcomes under more reproducible conditions.
A stay suture establishes a repeatable way to hold tissue or an incision in position during a procedure. More consistent exposure and reduced unwanted movement can make the manipulation easier to reproduce across specimens or experimental sessions. This standardization is relevant when researchers compare surgical outcomes, examine tissue responses, or evaluate procedures that depend on consistent anatomical handling.
The operator should monitor tissue alignment, the stability of the operative field, and the degree of traction applied through the suture. The support should maintain the intended position without producing visible distortion or unnecessary trauma. Continued attention to these factors helps preserve the tissue for the planned repair, dissection, specimen handling, or experimental observation.
