Summary
This study introduces a novel chicken thigh model for practicing anterolateral thigh (ALT) flap harvesting. This cost-effective, nonliving model allows for repeated training in perforator flap dissection, overcoming limitations of traditional animal models.
Area of Science:
- Microsurgery Training
- Surgical Simulation
- Anatomical Dissection
Background:
- Preclinical perforator flap harvesting training often relies on animal models, which are limited by ethical and economic factors, restricting repeated practice.
- Anterolateral thigh (ALT) flap harvesting requires specialized skills that benefit from extensive, repeatable training.
Purpose of the Study:
- To describe a novel, nonliving biological simulation model for training in perforator flap dissection.
- To evaluate the utility of a chicken thigh model for simulating anterolateral thigh (ALT) flap harvesting.
Main Methods:
- Ten chicken legs were utilized for anatomical dissection and flap elevation.
- Dissections were performed under magnification to identify perforator vessels and the vascular tree.
- A skin flap was designed based on the perforator's location.
Main Results:
- The perforator vessel was consistently identified in all specimens.
- The mean dissection time to harvest the flap was 88 minutes.
- Vessel diameters averaged 0.56 mm (artery) and 0.84 mm (vein).
Conclusions:
- This study presents the first description of an ex vivo chicken model for ALT flap dissection training.
- The chicken thigh model is a cost-effective, accessible, and repeatable alternative for preclinical perforator flap training.
- This model effectively simulates key aspects of ALT flap harvesting, preparing trainees for procedures on living models.

01:20Muscles that Move the Thigh
2.9K
The thigh's motion is primarily governed by muscles originating in the pelvic girdle and inserted into the femur. One crucial muscle, the iliopsoas, is a combination of the psoas major and the iliacus muscles, sharing a common insertion point on the lesser trochanter of the femur.
Three other significant muscles are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus maximus originates from the posterior surface of the ilium, sacrum, and coccyx, and the thoracolumbar...

01:22Esophageal Perforation-I: Introduction
591
Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus....

Following the work of Ernest Rutherford and his colleagues in the early twentieth century, the picture of atoms consisting of tiny dense nuclei surrounded by lighter and even tinier electrons continually moving about the nucleus was well established. This picture was called the planetary model since it pictured the atom as a miniature “solar system” with the electrons orbiting the nucleus like planets orbiting the sun. The simplest atom is hydrogen, consisting of a single proton as the...

01:28Esophageal Perforation-II: Clinical Manifestations and Management
715
Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.

15.4K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...
