– 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
– 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 Plafond Menu – Timing of Open Reduction: – in some cases, the fibula can be anatomically reduced along with application of external fixator which allows the fracture to be brought out to length and which allows the talus to be centered under the tibia; – then … Read more
– Discussion: – see flexion gap – is space between transverse cut on distal femur & transverse proximal tibial cut while the knee is in complete extension; – while minor loss of knee flexion or mild instability in flexion can be tolerated, priority is always be given to extension gap adjustments; … 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
– Inspection: – look at shoes for signs of abnormal wear; – inspect standing foot and ankle alignment from behind; – note arch height; – Assessment of Gait: – always examine the soles of the patient’s shoes for signs of asymmetrical wear; – look for … Read more
