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

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

2022
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.

We describe the detailed surgical procedures of calvarial suture-bony composite defects in rats, alongside the investigations into the short-term and long-term prognoses of the model. We aim to construct a standardized model for developing suture-regenerative therapies.
FAQs
The interlocking edges increase the mechanical stability of the junction between the parietal bones, while the connective-tissue seam preserves flexibility during development. This combination allows the skull to remain structurally organized without preventing expansion as the brain grows. The sagittal suture therefore illustrates how cranial design balances protection, alignment, and developmental change.
Flexibility allows the developing skull to adjust its shape during birth, a process known as molding of the infant head. Afterward, the sutural region continues to accommodate expansion associated with brain growth. These roles show that cranial sutures are not merely fixed seams; their connective tissue contributes to changing mechanical demands during important stages of development.
Premature fusion of the sagittal suture is called sagittal craniosynostosis. Because the affected junction can no longer support normal expansion in the same developmental pattern, skull growth may become restricted. Evaluation focuses on the resulting cranial shape and the child’s development, helping clinicians determine how early fusion has affected cranial structure.
Its midline location provides a consistent reference for identifying the relationship between the right and left parietal bones. In biology and medicine, this landmark supports anatomical description, embryological study, physical examination, and interpretation of imaging. Recognizing its expected position helps observers relate cranial shape and internal structural findings to the skull’s overall organization.
Assessment centers on cranial shape and development rather than on the suture alone. Clinicians consider whether the skull’s form suggests restricted growth and examine developmental status in context. Physical examination and imaging can provide complementary information, allowing the sagittal region to be interpreted as part of a broader evaluation of cranial structure and development.
The sagittal suture connects several biological themes: cranial organization, embryological development, brain-associated skull growth, and birth-related molding. Studying it shows how connective tissue can maintain stability while permitting developmental change. It also provides a direct context for understanding how abnormal timing of fusion can alter cranial form and prompt medical evaluation.
