– Rosenburg View: – used to evaluate for narrowing of the cartilage space in the wt. bearing, flexed knee position; – this provides a film with the anterior margin of the tibial plateau superimposed on the posterior margin; – technique: – patient is standing with the knees flexed at 45 deg; … 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: – 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

– Discussion: – multiple approaches can be used, but a medial approach is easiest w/ knee in extension as the patella can be rocked up anteriorly to aid in entry; – if pt will allow the knee to be flexed to 45 deg., then do so; – palpate the inferomedial and inferolateral borders … Read more
– Discussion: – Q angle is the angle formed by a line drawn from the ASIS to central patella and a second line drawn from central patella to tibial tubercle; – an increased Q angle is a risk factor for patellar subluxation; – normally Q angle is 14 deg for … Read more
– Discussion: – function of the PTFJ – accept 1/6 the axial load of the leg – resist torsional stresses originating from the ankle – resist tensile forces created with weight bearing – resists lateral bending forces – subluxation is common in preadolescent … Read more
– Discussion: – frx of proximal tibial metaphysis are rare; – valgus greenstick fractures usually occur between 3-6 yrs of age; – cortex is slightly opened on the medial side; – distal fragment is angulated lateralward; – Non Operative Treatment: – usually treated with closed … Read more
– See: – Defects of the Fibula: – Van Nes Rotational Plasty: – Discussion: – a development defect of the proximal femur recongnizable at birth; – 3rd most common longitudinal deficiency of lower extremity; – abnormality ranges from hypoplasia of entire femur to … Read more
