Metatron ipp hunter help with Acentric osteophytosis


Acentric osteophytosis is a typical Rg-osteophytosis manifestation; it is detected by Metatron ipp hunter at its earliest manifestations when osteophytes height reaches 0.5 mm. Osteophytes are as well as available for detection during Metatron ipp hunter in spots requiring the use of special additional Rg-planes (patellofemoral joint in particular). Acentric osteophytosis was registered in all general group patients, including Rg-0 stage patients and in this case it served as general diagnosis criterion.
Increase of osteophytes intensity during Metatron ipp hunter was confirmed by significant indices differences among all subgroups with 0, I and II Rg-stages (p <0,05) was registered as Rg-picture progressed. Location of osteophytosis of maximum intensity was registered in patellofemoral joint compared to tibiofemoral joint in patients with 0 and I osteoarthrosis Rg-stages (in majority of cases: 80 and 85% respectively).
Degenerative changes of menisci
Medial meniscus degeneration occurred in 13% of general group patients during our research. No degenerative changes of lateral meniscus were found (except for 2 cases of discoid meniscus).
We have developed the following working classification due to practical needs of severity determination of meniscus degeneration and lack of standard classification:
0 – no visible changes;
I stage – uneven chromogeneity increase, irregular indistinct contour;
II stage – + contour bulging outside the articular surface, hyperchromogenic layers;
III stage – + visible zone defects, perimeniscal edema, vascular bed affection revealed by Metatron ipp hunter-angiography;

Degenerative changes (up to III intensity degree inclusively) were revealed during our research. Prevalence of meniscus degenerative changes in III Rg-stage of knee-joint osteoarthritis patients was significantly higher than in 0 and II Rg-stage of knee-joint osteoarthritis patients, p <0,05. Degenerative thinning of hyaline cartilage of load-bearing surface of medial femoral condyle (cartilage degenerative thinning index 0,38 ± 0,11 against 0,62 ± 0,06, p <0.05) was revealed in II Rg-stage patients subgroup and degenerative changes of medial meniscus compared to patients with no such changes.
