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...

FAQs
The interlocking edges help the suture resist disruption, while its connective-tissue seam permits limited movement. This arrangement supports skull integrity without making the junction completely rigid. In developmental biology, that balance matters because the cranium must remain stable while still accommodating growth and remodeling during childhood.
During childhood, the seam supports coordinated expansion of the cranium as the brain grows. Its connective tissue and limited mobility allow the skull to preserve structural continuity while accommodating developmental enlargement. This makes the coronal suture useful for examining how bone growth and tissue remodeling contribute to changing cranial form.
Premature fusion closes the normal developmental seam too early. As a result, the skull may lose part of its capacity for coordinated expansion during brain growth. The resulting restriction can produce an abnormal head shape, which is why coronal craniosynostosis has diagnostic and developmental significance.
Researchers can examine this structure to connect several processes in one developmental setting: cranial formation, bone growth, connective-tissue behavior, and tissue remodeling. Because it changes as the cranium develops, observations of the coronal suture help frame questions about how skull shape and stability are maintained during childhood.
An abnormal head shape can signal that premature fusion has disrupted the suture's developmental role. In coronal craniosynostosis, restricted expansion links the structure's condition with skull form, so evaluation of head shape becomes relevant to diagnosis. This clinical connection also supports research into how altered development affects cranial growth.
Its normal developmental behavior provides a baseline for interpreting coronal craniosynostosis. Researchers can compare coordinated childhood expansion with the consequences of premature fusion, using the contrast to investigate cranial development, bone growth, and tissue remodeling. Clinically, this relationship explains why the suture matters beyond anatomy, particularly when abnormal skull shape or restricted expansion occurs.
