Adductor Canal Localization in Living and Cadaver

NCT07247591 | Not Yet Recruiting

Brief Summary

The aim of this study is to define the starting and ending points of the adductor canal in adductor canal block (ACB) applications through distance measurements relative to the anterior superior iliac spine (ASIS) and the adductor tubercle. These measurements are performed using ultrasound (USG) and correlated with cadaveric data. Key research questions addressed include:

• Can the start and end points of the adductor canal be formulated along a line drawn between the ASIS and the adductor tubercle?
• Is there a definable relationship between the block application site and anatomical landmarks such as the vastoadductor membrane (VAM), the apex of the femoral triangle, and other adjacent structures that facilitates localization? By validating ultrasound measurements with cadaveric findings, the study aims to provide researchers with a more predictable and reliable method for determining the optimal site for adductor canal block administration.

Study Population

He study at Etlik City Hospital will include patients who meet the following criteria: ASA classification of 1, 2, or 3, indicating individuals who are healthy or have mild to moderate systemic disease without major functional limitation; a BMI below 35 to exclude participants with obesity-related comorbidities; and an age range of 18 to 65 to ensure a broad yet controlled sample while avoiding age-related confounding factors.
