{"title":"Osteoporotic Vertebral Deformity: Radiological Appearances and Their Association With a History of Trauma and the Risk of Further Fragility Fracture.","authors":"Yì Xiáng J Wáng","doi":"10.1177/0846537120958471","DOIUrl":"https://doi.org/10.1177/0846537120958471","url":null,"abstract":"I read the recent article by Lentle et al with great interest. This article is significant in that it clarified that morphometric vertebral deformity (VD) is not associated with increased further osteoporotic fracture risk. Although these morphometric VDs have long been considered not to be true fracture by some authors, solid evidence had been lacking. On the other hand, these morphometric VDs have been over-called as osteoporotic vertebral fracture (OVF) by other investigators. In our experience, consistent with other publications and also that shown in Figure 1 of Lentle et al’s work, morphometric VDs often involve multiple adjacent vertebrae appearing similarly deformed, while fractural deformities tend more often to be singular appearing as a distinct loss of expected shape (as compared to adjacent vertebrae). In our interpretation of spine radiographs, morphometric VDs are generally regarded as degenerative changes and ignored for the purposes of osteoporotic risk assessment. Lentle et al classified suspected fractures into morphometric VD and mABQ (modified algorithm–based qualitative)-VDs which are VDs coexisting with endplate and/or cortical fractures (ECF). We reported that there is another category of radiological VDs which do not have ECF. These radiological VDs have a high risk of developing ECF and thus can turn into mABQVD during follow-up. In our MsOS(Hong Kong) study for elderly women, of radiological VDs with 25% to 33% measured height loss at baseline, 74% of them turned to fractures which meet mABQ criteria during 4 years’ follow-up, and the progression of radiological VD severity is associated with an increasing probability of meeting mABQ-VD criteria during follow-up. Lentle et al argue against the diagnosis of wedge-shaped OVF. Vertebral fracture can occur among osteoporotic patients in 3 possible scenarios: (1) with minimal energy trauma which is often not noted or not recalled, (2) with distinct low-energy trauma which is defined as forces equivalent to a fall from a standing height or less, and (3) with high-energy trauma (these being much less common and not, by definition, OVF). Osteoporotic vertebral fractures in epidemiological studies and clinical screenings commonly appear as concave deformities which more often associated with minimal trauma. However, OVFs have varied appearances, and at least a portion may be similar to traumatic fracture and be wedge-shaped particularly when a distinct low-energy trauma event had been involved. Sugita et al classified vertebral fracture in osteoporotic patients into 5 types: swelled-front, bow-shaped, projecting, concave, and dented, with the first 3 types having a poorer prognosis with a higher incidence of late collapse and showing an intravertebral cleft during follow-up. In their cases, swelled-front-type, bow-shaped-type, and projecting-type fractures accounted for 58.3% of total fractures, while the concave type counted for 32.1%. Indeed, Sugita et al noted that concavetyp","PeriodicalId":444006,"journal":{"name":"Canadian Association of Radiologists journal = Journal l'Association canadienne des radiologistes","volume":" ","pages":"585"},"PeriodicalIF":3.1,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/0846537120958471","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38385849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Readers may not know that, purely by chance, within months 3 groups separately published upon the diagnosis of osteoporotic vertebral fractures from plain radiographs. Their results were similar and have been reviewed elsewhere. Dr Wang and his colleagues at the Chinese University of Hong Kong was one of these groups; the other 2 were Drs L and E. Oei, and F. Rivadeneira et al at the Erasmus University, Rotterdam and the CaMos Consortium in Canada. All 3 compared morphometric (measurement-based) and morphologic (structural-based) diagnostic methods. In total, the studies included over 5000 patients, most from Canada. Although there is broad agreement between the findings of these groups, protocols and practices differed slightly. For example, when Jiang and her colleagues at the University of Sheffield in the United Kingdom first developed a structured approach to fracture diagnosis they observed a counter-intuitive difference in the segmental distributions of morphologic and morphometric deformities in the spines of osteoporotic patients. That observation was repeated by the Dutch and Canadian investigators but not by those in Hong Kong. It transpires that the Hong Kong group had intuitively concluded that morphometric abnormalities in the thoracic spine were not of osteoporotic provenance and tended to lead to over diagnosis. For this reason such ‘‘lesions’’ were not included in their data. Because of such differences in diagnosis and in the terminology used there appears to be a need for a nosology of vertebral deformities and confounders in this context so that there is a consistency in identifying and reporting findings. It may seem quaint to be earnestly discussing plain image radiography in this era in which radiological innovation is dominated by the power of sectional imaging. However, plain spinal radiography plays an important clinical role in future fracture-risk assessment as part of osteoporosis care. Dr Wang’s observations suggest there may be yet more to learn from these images, although the Japanese work has yet to be validated. Not least, as one reflects on the chequered history of osteoporotic vertebral fractures diagnosis and as artificial intelligence and machine learning may come to play an increasing role in radiology practice, it will be even more important to look critically at received wisdom such that human misunderstandings are not perpetuated in machine protocols.","PeriodicalId":444006,"journal":{"name":"Canadian Association of Radiologists journal = Journal l'Association canadienne des radiologistes","volume":" ","pages":"586"},"PeriodicalIF":3.1,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/0846537120963692","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38464875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
