  2. 2. JSS Medical College, Mysuru Introduction.. (Barlow’s disease, hypovitaminosis C) • Pathology: • Vitamin C necessary for Endothelial lining : deficiency causes increased vascular fragility • Decreased osteoblastic activity and cartilage proliferation resulting in decreased formation of bony matrix • Normal mineralisation • Osteoporosis
  3. 3. JSS Medical College, Mysuru Radiologic features 1.Dense zone of provisional calcification (white line of Frankel). 2.Corner (angle) sign-Corner (angle) sign. Irregularity of the metaphyseal margins frequently occurs secondary to infarctions of the epiphyseal- metaphyseal junction. 3. Pelken’s spurs. 4. Scorbutic zone (Trümmerfeld’s zone). 5.Subperiosteal hemorrhage.
  4. 4. JSS Medical College, Mysuru PA Knee: Characteristic changes: 1. Generalized osteopenia, 2. Dense zone of provisional calcification, 3. Scorbutic zone, 4. Pelken’s spurs , 5. Wimberger’s sign (ring epiphyses) and 6. Subperiosteal hemorrhages
  5. 5. JSS Medical College, Mysuru WHITE LINE OF FRENKEL • White line in the zone of provisional calcification at the growing metaphysis • Dense zone of provisional calcification (white line of Frankel). • Cartilage proliferation decreased with normal mineralisation resulting in widened and dense zone of provisional calcification
  6. 6. JSS Medical College, Mysuru WIMBERGER SIGN • Epiphysis is small sharply marginated by sclerotic rim with central portion more radiolucent. • Due to decrease cartilage proliferation and unimpaired mineralization (sclerosis)
  7. 7. JSS Medical College, Mysuru TRUMMERFELD ZONE (SCORBUTIC ZONE) • Transverse radiolucent band adjacent to zone of provisonal calcification due to suppressed osteoblastic activity with normal mineralisation • Trabecular bone mass is decreased in zone of primary and secondary spongiosa. Scorbutic zone (Trümmerfeld’s zone).
  8. 8. JSS Medical College, Mysuru PELKAN’S SPUR • Zone of provisional calcification extends beyond the margins of the metaphysis resulting in periosteal elevation and marginal spur formation • These bony protuberances occur at the metaphyseal margins and extend at right angles away from the shaft axis.
  9. 9. JSS Medical College, Mysuru CORNER (ANGLE) SIGN • Irregularity of the metaphyseal margins secondary to infractions of the epiphyseal-metaphyseal junction
  10. 10. JSS Medical College, Mysuru SUBPERIOSTEAL HEMORRAGES • Due to increased capillary permeability • Seen in ends of long bones(femur,tibia, humerus) • May cause periosteal elevation and new bone formation
