– Discussion: – effect on tibial bone supply: (see blood supply to the tibia) – unreamed nails theoretically minimizes disruption of the endosteal vasculature; – references: – Early changes in nutrient artery blood flow following … Read more
– See: – Arteriography, Microanastomosis, Pharmocological Agents in Vascular Surgery – Vaccum Assisted Wound Closure Device – Discussion: – w/ severe extremity wounds, early radical debridement combined with early soft tissue coverage (regional or free flap) will decrease wound infection, flap loss, & delayed bone healing; – early coverage … Read more
– Findings: – Assymmetrical osteopenia; – Spine: vertebral compression fractures; – Skull: – so-called salt-and-pepper skull – tiny punched out lesions may be present in the skull, producing so called salt and pepper appearance; – Clavicle: erosion of the … Read more
– See: Radiology of the Acetabulum – Discussion: – instability = cephalic displacement of posterior sacroiliac complex of at least 5-15 mm on inlet and outlet views; – look for gap (rather than impaction) posteriorly, & frx of 5th lumbar transverse process or avulsion of sacrospinous ligament; – Pertinent Radiographs: – AP … Read more
– 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: – 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
– Discussion: – flexion-extension laterals; – prior to intubation for elective surgery, all patients at risk should have flexion extension laterals of cervical spine r/o atlantoaxial instability; – Radiographs: – atlantodens interval (ADI) needs to be evaluated; – instability is … Read more
– Lateral View: – key element is whether there is anterolithesis, since this will dramatically narrow the SAC w/ any degree of rotation; – ADI: – it may be difficult to measure the ADI due to lateral mass rotation; – in children … 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
– PA view: – common finding is small frag from ulnar base of proximal phalanx; – Lateral view: – may show volar subluxation of proximal phalanx that would indicate that there is a tear involving the dorsal capsule & EPB; – more than 3 mm of subluxation … Read more
