– See: PreOp Planning: – Discussion: – a candidate for HTO should have relatively normal lateral and patellofemoral compartments; – degenerative changes confined to medial compartment should be apparent in x-rays, although minor arthritic changes in lateral compartment or patellofemoral joint are not absolute contraindications – HTO is contraindicated w/ lateral compartment or patellofemoral symptoms … Read more
– See: Radiology of the Elbow – Discussion: – note that accurate AP and Lateral views are essential to judge the reduction; – slightly oblique views can lead to acceptance of malreduction; – AP View: – comparison films are usually required to judge amount of relative varus; … Read more
– See: – Radiographic Evaluation of the Talus – Radiographic Studies for Ankle Fractures – Radiographic Studies for Ankle Sprains – Mortise views – medial clear space – talar tilt – tibio-fibular line – talocrural angle – Anteroposterior – … Read more
– See: Radiographic Studies of the Foot and Ankle – Lateral of Ankle: – Mortise Views: – syndesmotic injury; – medial clear space should be less than 4 mm and superior- medial joint space w/ in 2 mm medially of its width laterally; – due … Read more
– Anatomy of Olecranon: – Radiology: – insist on a true lateral X-ray of the elbow joint to evaluate: – extent of frx & displacement: – non comminuted = displacement of less than 2 mm; … 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: 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
– Discussion: – coalition bewteen talus & calcaneus may be difficult to detect on xray – cartilaginous coalition between the talus and calcaneus in the area of the middle facet may also be detected by an irregularity of the joint surfaces of the talus and calcaneus; – anterior facet is … Read more
– Discussion: – radiographs of knee hemarthrosis, may show the capsule in distension; – synovitis, cartilage thinning, widening and ersion of intercondylar notch; – enlargement of ossification centers, esp distal end of femur; – hemorrhage can displace periosteum to such extent that huge soft tissue mass results … Read more
– See: X-rays of the Foot – Radiographs: – broden’s view: – dorsoplantar (AP): – delineates calcaneocuboid joint – demonstrates amount of lateral spread of calcaneus – demnstrates subluxation of talonavicular joint; … Read more
