– Discussion: – see: limb development and physeal anatomy; – leg length discrepancy leads to awkward gait, & pelvic obliquity. – treatment of limb length inequality, requires an ability to predict leg length discrepancy at skeletal maturity; – differential diagnosis of limb length inequality – … Read more
– See: Methods to Etimate Growth Potenital – Arrest of the Growth Plate / Epiphysiodesis: – disruption of contra-lateral (normal) distal femora or proximal tibial growth plates is indicated when future discrepancies are < 5.1 cm at maturity; – references: – Closed shortening of the femur … Read more
– Discussion: – the ligaments of Humphrey and Wrisberg are meniscofemoral ligaments which run from the posterior horn of the lateral meniscus to the lateral aspect of the medial femoral condyle; – these ligaments are named based on their location in relation to the PCL; … Read more
– See: Tibial Plateau Frx Menu, Rim Fractures – Ligaments: – 60% of plateau frx will have ligamentous instability; – MCL accounted for 55%, LCL injuries for 22%, & combined cruciate & collateral injuries for 23% of lesions. – these may have poor prognosis; – Exam: – w/ isolated … Read more
– See: Limb Lengthening Fixators Post Op Care in the Ilizarov Method: (by Dr. Mangal Parihar) distraction histiogenesis – Discussion: – lengthening thru the proximal tibia, tends to drift into valgus and procurvatum, and therefore consider presetting distraction in 5 deg of varus; … Read more
– See: Synthes Plates and Screws:3.5 MM DCP, LC-DCP 3.5 MM LCP 4.5 MM LCP RECONSTRUCTION PLATE – Dynamic Compression Plates: – Properties of Titanium; – Discussion: – is used for same indications as DCP, but the improved design offers additional advantages; – undercut plate holes: undercut at each … Read more
– Discussion: – theory based on reproduction of frx patterns in cadavera; – rationale was to guide closed treatment of fractures about the ankle; – initial position of the foot is either supination or pronation; – supination of foot places tension on lateral structures of ankle; – pronation places … Read more
– See: Retinacular Release for TKR: – Discussion: – see lateral anatomy of the knee and blood supply to the knee; – lateral release detaches patella from lateral soft tissue structures, including lateral retinaculum, fibers from tensa fascia lata muscle, & joint capsule; – a successful release should release the lateral … Read more
– Discussion: Type I Fractures: – this is the wedge fracture of a lateral plateau; – it occurs mostly in young people since the dense cancellous bone of lateral plateau resists depression; – “Minimally Displaced Fractures” (from the Holh Classification) – frx shows depression … Read more
– Discussion: – when the frx is sufficiently oblique & is not comminuted, it can be treated w/ a lag screw to produce intrafragmentary compression, and neutralization plate placed laterally to prevent frx from slippling; – disadvantages of lateral plating: – prominent lateral screws may cause … Read more
