WHAT IS DIAGNOSTIC RADIOLOGICAL FINDING IN FLUOROSIS:-
A)SCLEROSIS OF SACROILIAC JOINT
B)INTEROSSEOUS MEMB CALCIFICATION……?
C)OSTEOSCLEROSIS OF VERTEBRAL BODY……?
D)OSSIFICATION OF LIGAMENT OF KNEE JOINT.

is it c)

xray findings in flurosis:

thickening of bony trabecular pattern seen in vertebral bodies

periosteal proliferation

ligamentous calcification

It is interosseous ligament calcification
Pg.266 Maheshwari

But, increased density(sclerosis?) and calcification of sacro-iliac ligament also given ?????

Sites of calcification :
Ant long. ligament - Ankylosing spondylitis
Post. long. ligament - Flourosis
Meniscus - Pseudogout
IV disc - Ochronosis

satvik can u help???

SATVIK · Credits: 958 My Scrapbook

have no doubts
CALCIFICATION OF THE INTER OSSEOUS MEMBRANE OF THE FOREARM is characteristic feature of fluorosis

answer option B

shraddha · Credits: 19590 My Scrapbook

answer is C)

Salgunan says B
but if we read maheshwari we find no evidence of inter membranous calcification

i found something on net

"From the X-ray picture it is possible to differentiate between three phases of the same osteosclerotic process, each overlapping the next without any sharp boundary.

1st Phase.

"The changes are observed in pelvis and columna, but are doubtful or absent elsewhere. The density of bone is very little increased. The trabeculae are rough, blurred and give deep shadows; this is often distinct in corpora of the lower lumbar vertebrae. The bone has both a more prominent and a more blurred structure at the same time, which is very characteristic when the operator is familiar with the phenomenon, but otherwise is easily overlooked. The bone contour is sharp. In some few cases there is incipient osteophyte formation on the edge of corpora of the lumbar vertebrae. The boundary against the normal bone structure is not sharp, and in an isolated case it will be difficult to decide whether the change is a normal variation or a pathological finding. In serial examinations, however, the difference is distinct.

2nd Phase.

"The bone structure is blurred, the trabeculae merging together. Over often rather large areas the bone gives a diffuse, structureless shadow. At first glance the negative seems to have been underexposed, but it is difficult or impossible to distinguish details even when the time of exposure or the tension is increased. The bone contours are uneven and somewhat blurred. The changes are most distinct in pelvis and columna, but also in the ribs and in the bones of the extremities, even if there they are less pronounced and often resemble the changes described as 1st phase. In the extremity bones the medullary cavity is usually moderately narrowed. In columna there are incipient or moderate ligament calcifications, especially caudally; they appear in the form of pointed, beaked osteophytes with an inclination to form bridges between vertebral bodies or as a diffuse blur lying posteriorly to corpora. In some cases (particularly among the younger individuals) the ligament calcifications are absent, though the bone structure is so changed that the case must be placed to the 2nd phase.

3rd Phase.

"On the negative the bone presents itself as a more or less diffuse marble-white shadow, in which the details cannot be distinguished. Changes are observable in all bones but are still greatest centrally, being most conspicuous in bones with cancellous structure, pelvis, columna, ribs and sternum. In the bones of the extremities there are changes in the structure that recall the 2nd phase, or fairly often only the 1st phsase. Among the worst affected individuals changes are to be seen in the cranium, usually rather moderate in intensity. Theca is denser and gives a deeper shadow than normally, sutures and vessel grooves are indistinct, and the same applies to impressiones digitatae. The air-sinuses in the cranial bones are diminished in size. The region around sella turcica gives a deep shadow but is normal as to contour. No distinct thickening of the processus clinoidei was observed.

The diagnostic radiological findings - included osteosclerosis, particularly of the spine, pelvis and thorax, periosteal bone formation, irregular exostoses, calcification of ligaments of interosseous membrane and muscular attachments . The joints showed calcifications in the capsule, chondrocalcinosis, epiphyseal sclerosis, articular erosions, osteoporosis and osteophytosis.
