Osseous is an adjective which relates to bones, their structure or nature. Like many words in European languages, it derives from the Latin words for bone 'os' and 'ossis'.
Abnormality is an adverb meaning 'not normality'. This also derived from Latin, the words 'norma' meaning 'rule' and 'ab' meaning 'from'.
From a medical perspective, it can refer to any bones in the body that possess unusual properties, usually to the detriment of the patient. Osseous Abnormality often implies a reduction in strength in the affected bone or bones leading to an increased chance of fractures.
