Changes in the Appendicular Skeleton with Age

Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Bones of the Lower Limb: Tibia and Fibula

Bones of the Lower Limb: Tibia and Fibula

The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Area of Science:

Obstetrics and Gynecology
Medical Simulation
3D Printing in Medicine

Background:

Podalic version and breech extraction demand advanced obstetrical skills.
Accurate identification of fetal extremities is critical for trainees.
Inadequate skill in fetal extremity identification can prolong delivery intervals and complicate procedures.

Purpose of the Study:

To develop and evaluate a novel simulation model for training fetal extremity identification.
To improve trainee proficiency in skills required for podalic version and breech extraction.

Main Methods:

A simulation model was created using a birth mannequin and 3D-printed fetal hands and feet.
3D models of fetal extremities were created from ultrasound data.
Hands and feet were placed in water-filled condoms within a pelvic mannequin for tactile simulation.
Trainee performance was assessed before and after using the simulation model.

Main Results:

A significant reduction in the mean time to extract the first foot and all feet was observed.
The simulation model effectively trained and assessed the targeted obstetrical skill.

Conclusions:

The developed 3D-printed model provides a viable training and assessment tool.
This method enhances a critical skill for performing safe and efficient version and breech extraction procedures.
