Saber shin is a malformation of the tibia. It presents as a sharp anterior bowing, or convexity, of the tibia. Causes
Periosteal reaction along the shaft of the tibia. It can result from congenital syphilis, yaws, Pagets disease of bone, vitamin D deficiency or Weismann-Netter–Stuhl syndrome. It can be due to osteomalacia. Prognosis
Etymology

A pulmonary consolidation is a region of normally compressible lung tissue that has filled with liquid instead of air. The condition is marked by induration (swelling or hardening of normally soft tissue) of a normally aerated lung. It is considered a radiologic sign. Consolidation occurs through accumulation of inflammatory cellular exudate in the alveoli and adjoining ducts. The liquid can be pulmonary edema, inflammatory exudate, pus, inhaled water, or blood (from bronchial tree or hemorrhage from a pulmonary artery). Consolidation must be present to diagnose pneumonia: the signs of lobar pneumonia are characteristic and clinically referred to as consolidation. Signs
Signs that consolidation may have occurred include:

Expansion of the thorax on inspiration is reduced on the affected side
Vocal fremitus is increased on the affected side
Percussion is dull in the affected area
Breath sounds are bronchial
Possible medium, late, or pan-inspiratory crackles
Vocal resonance is increased. Here, the patients voice (or whisper, as in whispered pectoriloquy) can be heard more clearly when there is consolidation, as opposed to the healthy lung where speech sounds muffled. A pleural rub may be present. A lower PAO2 than calculated in the alveolar gas equation

Diagnosis
Radiology
Typically, an area of white lung is seen on a standard X-ray. Consolidated tissue is more radio-opaque than normally aerated lung parenchyma, so that it is clearly demonstrable in radiography and on CT scans. Consolidation is often a middle-to-late stage feature/complication in pulmonary infections. See also
