5 Unicameral bone cyst Next to growth plate Active vs Inactive Falling leaf sign
6 ABCAneurysmal bone cysts may occur in patients aged years, with a peak incidence in those aged 16 years.About 75% of patients are younger than 20 years.Four phases of pathogenesis are recognized, as follows:Osteolytic initial phaseActive growth phase, which is characterized by rapid destruction of bone and a subperiosteal blow-out patternMature stage, also known as stage of stabilization, which is manifested by formation of a distinct peripheral bony shell and internal bony septae and trabeculae that produce the classic soap-bubble appearance.Healing phase with progressive calcification and ossification of the cyst and its eventual transformation into a dense bony mass with an irregular structure.
13 Osteochondromas or Multiple Exostoses Cartilaginous cap covered by a bursaImpinge on local structuresCT shows cap < 1cm in thicknessCan be excised due to structural problemsSMALL incidence (<1% per lesion) of transformation to Chondro sarcoma (or Osteogenic less common)
14 Multiple Exostoses Found in areas around growth plates Can occur in multiple locations or singularlyUsually not NeoplasticBone with cartilaginous capGrows normally with growth of the rest of the skeleton

28 Twisty Bendy Feet Most common is metatarsus adductus FPS fetal packaging syndromeNormal rotation of feet in uteroShould respond to gentle massage and SWNShoes could be worn in reverse (r-l l-r) if there is any “last” in the shoe
29 Metatarsus adductus/clubfoot (tell tale medial crease)
30 Twisty Bendy Feet Clubfeet “talipes equino-varus” Metatarsus adductus, heel equinus and varus and talus adductusTell tale crease on lat underneath malleolusThinning and atrophy of lower legNeeds attention based on severity of deformity, START TREATMENT AT BIRTH !!! Refer early
37 Twisty Bendy Legs Internal Tibial Torsion Normal adult rotation is degrees externalNormal unwinding of child's lower legsNot significantly affected by orthotics or treatment !!!Sight along tibial crest and look at malleoliReassure (look for other conditions)
