– Origin: – middle 1/2 of the anterior surface of the fibula and adjacent interosseus membrane. – the EHL lies dorsal to the EHB and is prevented from subluxation by the dorsal extensor hood; – Insertion: – dorsal surface of base of distal phalanx of hallux – Nerve supply: … Read more
– Discussion: – extension type accounts for 95% of cases, & is caused by a fall on outstretched hand with hyperextension of the elbow; – anterior periosteum is torn; – there may be a significant amount of local bleeding and swelling; – nerves & blood vessels are contused, compressed, … Read more
– See: Forearm Extensors : – Anatomy: – origin: lateral condyle of humerus; – insertion: – this tendon inserts into the base of 3rd metacarpal and is in direct relationship with the ECRL, which inserts into the base of the 3rd metacarpal; … Read more
– See: Forearm Extensors: – Anatomy: – origin: lower 1/3 of lateral epicondyle & supracondylar ridge; – insertion: posterior surface of base of second metacarpal; – action: extends and abducts the hand at the wrist; – synergists: ECRB, ECU; – nerve supply: radial, … Read more
– See: Forearm Extensors : – Anatomy: – origin: 2 heads from lateral epicondyle & middle 1/3 of posterior ulna; – insertion: – posterior surface of base of 5th metacarpal; – ECU is the only wrist extensor that lies in its own fibro-osseus tunnel; – action: extends and adducts the hand at the wrist; – … Read more
– See: Forearm Extensors: – Anatomy: – origin: common extensor tendon off lateral epicondyle; – insertion: tendon of extensor digitorum at proximal phalanx of little finger & into dorsal expansion of finger extensor tendons; – action: – extends proximal phalanx of little finger at MP … Read more
– See: – Anterior Approach to Radial Shaft: – @<c:ovvuimgp -s c:osdiagfor.1[Diagram – Plating Techniques: – Discussion: – incision begins distal to flexor crease of elbow & extends distally for approx 15 cm along the anterior border of brachioradialis; … Read more
Discussion – descision to excise the head of the radius depends associated elbow injuries as well as severity of radial head frx; – it has been determined that the stabilizing effect of radial head comes into play only when the MCL ligament has been disrupted, which explains why excision of radial head (w/ … Read more
– Technique: – patient is placed on a bean bag in a true lateral position; – slightly flexing the knee and placing it on a padded Mayo stand may facilitate positioning; – calcaneus is approached thru an extensile right angled incision, which curves sharply between … Read more
– Clinical Findings: – history: patient may complain of a subjective knee hyperextension sensation, and twisting or pivoting are also difficult; – lack of contained effusion is suggestive of posterolateral capsular injury; – look for diffuse tenderness over the posterolateral joint region, fibular head, and joint line; … Read more
