Data Trace Editor – See: Growth Deformities of the Limbs: – Discussion: – straight-line graph based on a logarithmic scale of relative rates of limb growth along w/ expected discrepancy at maturity; – straight line graph also allows estimation of how epiphysiodesis will affect the long lower limb at different ages; – graph requires … Read more
– Mosaicplasty: – refers to the technique of harvesting small circular (4-8 mm) autogenous grafts from the knee from non wt bearing regions of the knee, and transplanting the grafts in a mosaic pattern until the osteochondral defect is filled; – typically the grafts are harvested from the periphery of the supero-lateral trochlea, but often, the … Read more
– Discussion: – it is not a neuroma but a perineural fibrosis and it was not first accurately described by Morton but by Durlacher, a chiropodist in 1845; both Thomas G. Morton (1876) and Thomas K. Morton (1892) mistook it for a painful affection of the fourth MTP articulation – it is a type of nerve compression … Read more
– Evaluate for: – lateral talar shift: – medial clear space – deltoid injury – fibular shortening; – talocrural angle – tibiofibular line – fibular rotation, or lateral displacement; – tibiofibular line – syndesmotic integrity (see radiographs) – talar tilt: (stability) – osteochondral lesions of talus – Discussion: – fibular length, talar tilt, talar … Read more
– see: structural bone grafts: – Discussion: – can be used to help recreate bone stock w/ protrusio, cavitary, or medial wall deficiency; – cannot be expected to provide ingrowth or stability, but over time the morselized graft can undergo revascularization and remodeling; – antiprotrusio cage or gap cup can be placed over the … Read more
Discussion short trunk disproportionate dwarfism is established by age of 2 or 3 and progresses; inherited as autosomal recessive trait; children have normal intelligence and survive well into adulthood; pectus carinatum is also apparant; other problems include corneal opacity and abnormal dentition; type of mucopolysaccharidoses in which keratan sulfate accumulates in the tissues; measurement of … Read more

– See: – Plating Techniques – Monteggia Fractures in Children – Discussion: – Giovanni Monteggia (1814) first described frx of proximal 1/3 of ulna in association w/ anterior dislocation of radial head; – hence dislocation of radial head w/ frx of proximal 1/3 of ulna is known as Monteggia’s deformity. – Mechanism: – proposed … Read more
– See: Monteggia Fractures in Adults – Discussion: – all four types of Monteggia frx dislocation are pertinent to children, including Monteggia equivalents; – diff dx: Monteggia equivalent (w/ fracture of proximal radius rather than dislocation of the radial head); – Classification: – type I: – anterior dislocation of the radial head w/ apex anterior … Read more
