Epiphysis:
-Expanded articular end of long bone.
-Developed from secondary ossification center.
-Later becomes united with main bone.
Epiphysis:
Physis:
-Responsible for lengthening.
-Growth plate.

Apophysis:
-Area where pressure or traction from soft tissue. Like tendon.
Apophysis:
where diaphysis and epiphysis meet.
Metaphysis:
shaft of bone.
Diaphysis:
Primary ossification center:
Primary ossification center:
Secondary ossification center:
Secondary ossification center:
-Radiographically: growth center looks fragmented or sclerotic.
-Can be from a variety of causes.
-Symptoms: pain and stiffness.
-Children or teens.
Osteochondrosis:
Legg Calve Perthes:
(Perthes disease)
-Osteochondrosis of femoral head.
-More common in *boys.*
*-5-16 years of age.*
-Increases risk of developing osteoarthritis.
Legg Calve Perthes:
(Perthes disease)
Osgood-Schlatter's:
-Tibial tuberosity.
-More common in *boys.*
-Usually between the *age of 10-15.*
Osgood-Schlatter’s:
-May be due to trauma, vascular insults.
*-Painful collapse of 2nd metatarsal head.*
-*Women* to men by 5:1.
-Usually adolescents.
-Almost always *unilateral.*
Freiburg’s Infraction:
Sever's:
-Calcaneal apophysitis.
-8-12 years old.
Sever’s:
Kohler's:
*-Navicular.*
-Usually between *6-9 years.*
Kohler’s:
Iselin's:
*-5th metatarsal base.*
-Occurs in children *between 8-13 years of age.*
-Most often in physically active boys.
Iselin’s:
Fibular sesamoid.
Trave’s disease:
Tibial sesamoid.
Renander’s disease:
Cuneiforms.
Buscke’s disease:
Talus.
Diaz disease:
Cuboid.
Lance’s disease:
Phalanges.
Thiemann’s disease:
Metatarsus adductus
Metatarsus adductus
Vertical Talus:
-Rigid rocker bottom flatfoot.
-Characteristic radiographic feature is dorsal dislocation of the navicular on the talus.
-Talus appears very declinated.
-Maximum plantarflexion lateral view: positioning technique.
-Ideal if the navicular is present.
Vertical Talus:
Talipes equinovarus:
(Clubfoot)
3 Components
1. equinus.
2. adductus.
3. varsus.
-Forced dorsiflexion lateral can be helpful in determining severity.
-TC angle on DP view is very decreased.
-1 met position is grossly varus much more than met adductus.
-Significant forefoot varus.
Talipes equinovarus:
(Clubfoot)
Calcaneal Valgus:
-Most common congenital deformity.
-Result of intrauterine position (foot is pushed against anterior aspect of leg).
-Foot is maintained in *abduction, eversion, and dorsiflexed position.*
-In DP view, foot is abducted relative to the talus. Greatly increased talocalcaneal angle (Kite’s angle).
-Lateral view, calcaneal inclination angle is decreased, talar declination angle is increased.
-Forced plantarflexion lateral x-ray is recommended .
Calcaneal Valgus:
inner curvature of pinky.
Clindactyl:
