Description
Background: The supinator muscle is located in the forearm and plays a role in the rotation of the forearm. Understanding the anatomy of the supinator muscle, including its layers and specific regions like the distal ar-cade, is important for healthcare professionals, especially in fields such as anatomy, physical therapy, and Or-thopaedics. Aim and Objectives: To make a detailed anatomic description of the distal arcade of the supinator muscle and its relation with the PIN. Materials and Method: This was an observational study done on 50 upper limbs belonging to 25 adult cadav-ers (17 males and 8 females) available in the Department of Anatomy, Chalmeda Anand Rao Institute of Medi-cal Sciences, and Karimnagar. The age of the cadavers ranged from 35 to 86 years. Study was conducted after getting permission from institutional ethical committee and after following inclusion and exclusion criteria giv-en below for the duration of 2 years. Results: In the present study 50 forearms and elbows were dissected. The nature of the distal arcade of superfi-cial layer of supinator muscle that was most commonly seen was the muscular type 21(42%), followed by the musculotendinous and tendinous types. Conclusion: Knowledge of the anatomic findings of the distal arcade of the superficial layer of the supinator and the localization of the PIN are important in the surgical management of PIN entrapment.
