– 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: 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
– Discussion: – anterior longitudinal ligament inserts on anteroinferior portion of the C2 body; – w/ extreme hyperextension, ligament may remain intact but may avulse from its insertion, pulling a corner of C2 body with it; – vertical ht of the fracture fragment is > than its horizontal width; – hyperextension … Read more

(See also: 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 7-21 days later, medial column and articular surface can be restored … Read more
