Among available papers published on the given subject over the last century, various terms have been used as synonyms for one, now generally accepted—osteoarthritis, in some countries called “wear and tear” or “overload arthritis”. The opsolent terms—hypertrophic arthritis, degenerative arthritis, arthritis deformans and osteoarthrosis—sought to highlight the dominant clinical signs of this ubiquitous, polymorph disease of the whole osteochondral unit, which by incidence and prevalence represents one of the leading chronic conditions that cause long-term pain and incapacity for work. Numerous in vitro and in vivo research resulted in broadened acknowledgments about osteoarthritis pathophysiology and pathology on both histological and cellular levels. However, the cause of osteoarthritis is still unknown and is currently the subject of a hypothesis. In this paper, we provide a review of recent findings on biological phenomena taking place in bone tissue during osteoarthritis to the extent useful for clinical practice. Choosing a proper radiological approach is a conditio sine qua non to the early diagnosis of this entity.

Giant Cell Tumor of the Distal Ulna: Multimodal Radiological Investigation of a Very Rare Location - Article abstract #932130

Cilj: U ovome radu prikazujemo vrlo rijedak rendgenski i ultrazvučni nalaz u akutnoj egzacerbaciji periartritisa ramena. Prikaz slučaja: Temeljna lezija lokalizirana je tipično u tetivi m. supraspinatusa i inflamiranoj subakromijalnoj burzi u kojoj je radiološki dokazan izljev bogat otopljenim kalcijevim solima (engl. milk of calcium). Ovakav se rendgenski i ultrazvučni nalaz u kliničkom radu, a tako i u literaturi, rijetko zabilježi jer je vezan za tranzitornu, mehaničku fazu u evoluciji periartritisa tijekom koje solidni periartikularni vapneni depoziti prelaze u tekuću suspenziju. Zaključak: Radiološka dijagnostika, u prvom redu rendgenski i ultrazvučni pregled optimalne su metode za dijagnostiku, diferencijaciju i praćenje periartritisa.
