A Simple and Concise Explanation of the Cubital Fossa with Dr. Shrikant Verma | Cerebellum Academy

Welcome to our detailed walkthrough of the Cubital Fossa, an essential topic for NEET PG, FMGE and INI CET aspirants. In this video, Dr. Shrikant Verma, a distinguished faculty of Anatomy at Cerebellum Academy, provides an in-depth exploration of the triangular muscular depression located in front of the elbow, also known as the Cubital Fossa. Let's dive into the anatomical features, boundaries, and clinical relevance.
.
Key Points Covered in the Video:-
✅ Triangular Muscular Depression:
~ This depression is known as the Cubital Fossa.
~ Clearly visible in front of the elbow.
✅ Boundaries of the Cubital Fossa:
~ Lateral Boundary: Formed by the brachioradialis muscle.
~ Medial Boundary: Formed by the pronator teres muscle.
~ Base: Formed by an imaginary line passing through the condyles.
~ Roof: Composed of skin, superficial fascia, and deep fascia.
✅ Contents of the Cubital Fossa:
~ Median nerve
~ Brachial artery
~ Tendon of the biceps
~ Radial nerve
~ Mnemonic for remembering: MBBR (Median nerve, Brachial artery, Biceps tendon, Radial nerve)
✅ Clinical Relevance:
~ Supracondylar Fracture: Can damage the median nerve, leading to the gun stop deformity.
~ Brachial Artery Involvement: May cause Volkmann's ischemia, ~ characterized by the five Ps: pain, pallor, pulselessness, paresthesia, and paralysis.
~ Biceps Tendon Injury: Affects the biceps jerk reflex.
~ Radial Nerve Damage: Results in wrist drop.
✅ Muscles Forming the Floor:
~ Mnemonic: BSF (Brachialis, Supinator, and Floor muscles)
~These muscles support the floor of the Cubital Fossa.
✅ Important Integrations and MCQs:
~ The radial nerve divides into superficial and deep branches.
~ The deep branch pierces the supinator muscle and becomes the posterior interosseous nerve.
Additional Notes:
~ The Cubital Fossa is frequently tested in exams like INICET and FMGE.
~ Understanding its anatomy and clinical implications is crucial for surgical and orthopedic practices.
~ This video also honors the dedication of our armed forces, drawing a parallel to the strength and support they provide, much like the structures in the Cubital Fossa.
