– See: – Posterior Interosseous Nerve Syndrome : – Radial Nerve Palsy Associated w/ Humeral Shaft Frx: – Radial Nerve Block – Tendon Transfers for Radial Nerve Palsy: – Anatomy: – three posterior divsions of brachial plexus form posterior cord: (C5 , C6 , C7, C8, T1) – radial nerve (C5, C6, C7 , C8 … Read more
– Discussion: – indicated for comminuted radial head frx which occur w/ concomitant MCL injury, dislocation, or RU joint disruption (Essex Lopresti Fracture); – will serve as spacer & will prevents proximal migration of radius; – w/ RU joint disruption, radial head spacer alone does not restore satisfactory axial stability w/o pinning the distal radioulnar … Read more
– Discussion: – mean radial inclination was 24 degrees (range, 19 to 29 degrees); – measured on PA view, & describes relative angle of distal radial articular surface to a line perpendicular to long axis of the radius; – this angle normally measures between 16 and 28 deg, av … Read more
– See: Radial Radial Inclination – Discussion: – radial-ulnar translation of hand on forearm is may be used in realigning distal radial fragment on the radial shaft; – w/ ulnar translation, the 1st and 2nd extensor compartment tendons and their associatted retinaculum create a radial soft tissue hinge; … Read more
– Discussion: – most commonly found in medial aspect of lateral meniscus; – radial tears of the posterior aspect of the lateral meniscus may be found in association with an anterior cruciate disruption; – may be associated w/ meniscal cysts which do not have to be removed … Read more
– See: – Adult Radial Neck Frx and Radial Head Frx; – Pediatric Elbow Injuries – Discussion: – radial neck frx are more common in children, whereas frx of radial head occur primarily in adults; – site of frx in childhood is either thru physis w/ … Read more
– Discussion: – presents w/ differing degrees of shortening (or absence) of radius, carpal bones, and radial rays (including thumb); – bowing of the ulna may contribut to the deformity; – elbow may have fixed extension contracture or may have deficit of active motion; … Read more
– Discussion: – as with ulnar injuries, a mid subtance tear is rare; – Treatment Acute Tears: – if there is no instability and no sign of volar subluxation, the thumb is immobilized for 3 to 4 weeks; – Surgical Treatment: – after curved incision and mobilization of skin flaps, … Read more
– See: – Adult Radial Neck Frx / Pediatric Radial Head Frx – Discussion: – radial head frx is most common type of elbow fracture in adults; – frx of the radial head occurs primarily in adults, whereas fractures of the radial neck are more common in children; – frx of the radial head and … Read more
– See: – Dislocations of Elbow: – Radial Head Frx: – Management of Complex Elbow Dislocations – Discussion: – upto 10 % of comminuted frx of radial head occurr in assoc w/ elbow dislocation; – there is usually significant soft tissue injury of both joint … Read more
