Medial Release

– Discussion: – following are components of a Medial Release: – recession or excision of abductor hallucis; – elongation/release of – tibionavicular portion of deltoid ligament – tibialis posterior tendon – talonavicular joint capsule – talocalcaneal joint capsule – interosseous ligament (only rarely performed) … Read more

– See: – Bicondylar Fractures and Type V Fractures: – Split Fractures: – Surgical Approach: Medial Compartment: – Type IV Fractures: – Total Depression Fracture: – X-ray: – if knee is unstable (greater > 5 deg instability), stress … Read more

Median Artery

– See: Arterial Development of the Limbs: – Embryologic Anatomy: – subclavian artery projects into early upper limb bud in axial position, its proximal portion becoming subclavian-axillary- brachial trunk, & its distal portion becoming interosseous artery that initially supplies a plexus of arteries in the primitive hand; … Read more

Medial Patellofemoral Ligament

– Anatomy and Function: (see medial compartment of knee / patellar subluxation); – medial patellofemoral ligament, a distinct condensation of capsular fibers in coronal plane which originates at the medial epicondyle (adductor tubercle and adductor tendon) as well as the MCL; – deep fascia and aponeurotic edge of the VMO fuses with the superior border … Read more

Medial Plateau: Surgical Approach

– See: – Medial Tibial Plateua Fractures: – Discussion: – on medial side, plate is applied to anteromedial face of proximal metaphysis deep to pes anserinus & anterior fibers of MCL; – Incision: – incision begins over medial femoral condyle, continues anterodistally then crosses the joint line near the … Read more

Medial Portals

– Anteromedial Portal: – for visualization of the lateral compartment, and instrumentation of the the medial compartment; – this portal is located in a manner similar to the anterolateral portal, that is, 1 cm above the medial joint line and 1 cm medial to the edge of the patellar tendon; … Read more

Medial Epiondylectomy for Cubital Tunnel Syndrome

– Discussion: – motivation: w/ maximal elbow flexion, high extraneural pressures occur at the medial epicondyle; – hence the medial epicondyle is a major impinging structure which forces the ulnar nerve to make a sharp turn whenever the elbow is maximally flexed; – medial … Read more

Medial Femoral Circumflex Artery

– See: – blood supply for femoral head; – external rotators of the hip – Discussion: – MFCA supplies majority of blood supply to femoral head; – branches of MFCA enter capsule of hip joint near its distal insertion and couse proximally along femoral neck toward … Read more
