– See: Radiographic Studies of the Foot and Ankle – Static Films: – os subfibulare: – historically, this has been considered to be an accessory ossicle located just below the ditsal fibular epiphysis; – it is distinguished from a fracture … Read more
– AP and Lateral: – radiographs are assessed for frx locations, displacement, alignment; – lateral plateau is convex from front to back & side to side, whereas medial one is concave; – lateral plateau is higher than medial one, which indicates amount of plateua … Read more
– See: – Radiology of the Wrist – Distal Radius Fx – Discussion: – radiographic measurements: – articular step off: most important determinant of outcome; – radial shortening second most determinant … Read more
– Discussion: – bone scan and MRI may help early involvement, but may not correlate with the extent of involvement; – bone scans are highly sensitive for Perthes disease; – Radiographic Findings: (Waldenstrom): – initial findings: – ossific nucleus fails to … Read more
– Discussion: – complete knee series should include an anteroposterior, lateral, & axilla view as well as a tunnel view in skeletally immature pts; – Specific Views: – Axilla View – Lateral Radiograph – Tangential Patellar Views – Tunnel Radiograph – X-ray Features of … Read more
– See: DDH – Indications for Radiographs: – for confirming position of hips getting treatment; – for confirming a suspected teratologic dislocation; – Patient age: – x-rays may not reveal a dislocation until infant is > 6 wks since so much of the pelvis is cartilaginous; … Read more
– Diagnosis: – early changes are limited to the soft tissues w/ fusiform swelling and joint effusion; – juxta-articular osteoporosis may become more generalized w/ dz progression; – cartilage destruction produces narrowing of the joint; – erosion of bone occurs characteristically in the metaphyseal region underlying collateral … Read more
– See: Radial Nerve: – Discussion: – superficial or sensory branch passes downward emerging dorsally from beneath Brachioradialis tendon about 5 cm proximal to radial styloid; they lies just deep to the superficial veins; – just proximal to the wrist, several branches fan out to provides sensory … Read more
– Discussion: – in forearm, attention is directed to interval between tendons of ECRL & Brachioradialis, which is optimal site of insertion for proximal half pin; – superficial branch of radial nerve emerges in interval between ECRL brachioradialis mentioned tendons & should be identified & protected when inserting … Read more
– Discussion: – may occur from frx (Galeazzi fracture or Colles frx), from radial head frx (as a part of an Essex Lopresti injury) or as an islated injury; – injury to the TFCC is a necessary part of this injury; – dorsal subluxation: … Read more
