Naturally occurring osteochondrosis latens lesions identified by quantitative and morphological 10.5 T MRI in pigs.

J Orthop Res 2022 Jun 18. Epub 2022 Jun 18.

Department of Veterinary Clinical Sciences, University of Minnesota Twin Cities, Minneapolis, Minnesota, USA.

Juvenile osteochondritis dissecans (JOCD) is a pediatric orthopedic disorder that involves the articular-epiphyseal cartilage complex and underlying bone. Clinical disease is often characterized by the presence of radiographically apparent osteochondral flaps and fragments. The existence of early JOCD lesions (osteochondrosis latens [OCL] and osteochondrosis manifesta [OCM]) that precede the development of osteochondral flaps and fragments is also well recognized.

Ultrasound screening protocol for osteochondrosis at selected predilection sites in thoroughbred yearlings.

Ir Vet J 2022 Apr 27;75(1). Epub 2022 Apr 27.

Equine Clinical Studies, Diagnostic Imaging and Anaesthesia, School of Veterinary Medicine, University College Dublin, Dublin, Ireland.

Background: Osteochondrosis is a common condition of young horses where there is a failure of endochondral ossification, usually at predisposed sites. The estimated prevalence of osteochondrosis is 33-44%, with radiographic screening of yearlings being used to identify lesions. Radiography has two major limitations: poor sensitivity in detecting cartilaginous lesions and secondly, the exposure of the horse and personnel to ionising radiation. Read More

Distribution Patterns of Degeneration of the Lumbar Spine in a Cohort of 200 Patients with an Indication for Lumbar MRI.

Int J Environ Res Public Health 2022 03 21;19(6). Epub 2022 Mar 21.

Competence Center for Epidemiology and Health Services Research for Healthcare Professionals (CVcare), Institute for Health Services Research in Dermatology and Nursing (IVDP), University Medical Center Hamburg-Eppendorf (UKE), 20246 Hamburg, Germany.

Lower back pain is one of the most common causes of a reduced quality of life. Magnetic resonance imaging (MRI) is the best suited imaging technique to detect causes of that pain. We retrospectively evaluated the MRIs of the lumbar spine for 200 patients in order to describe the distribution of signs of degeneration with regard to age, sex, and position of the disc affected.

[Scheuermann's disease].

Orthopade 2022 Apr 15;51(4):339-348. Epub 2022 Mar 15.

Klinik für Orthopädie (Friedrichsheim), Universitätsklinikum Frankfurt, Marienburgstr. 2, 60528, Frankfurt am Main, Deutschland.

Scheuermann's disease represents the second most common deformity of the growing spine after the various forms of scoliosis. In cases of early diagnosis and mild kyphotic deformity conservative treatment with a brace and physiotherapy shows very good results; however, in cases of neurologic deficits, curve progression despite conservative treatment and increasing pain symptoms with a Stagnara angle of more than 70-75°, surgical treatment is meaningful. The surgical strategy can include posterior spondylodesis with prior anterior release or posterior instrumentation with posterior column osteotomy depending on the surgeon's experience. Read More

Imaging Review of Normal and Abnormal Skeletal Maturation.

Radiographics 2022 May-Jun;42(3):861-879. Epub 2022 Feb 25.

From the Divisions of Musculoskeletal Radiology (A.C.d.L.A., P.C.K.G., M.A.F.C., A.C.O.R., L.C.P., A.Y.A.) and Pediatric Radiology (M.S.T., T.D.G.), Laboratório Delboni Auriemo, DASA, São Paulo, Brazil; Department of Diagnostic Imaging, Universidade Federal de São Paulo, UNIFESP, São Paulo, Brazil (A.C.d.L.A., A.Y.A.); Department of Radiology, St. Paul's Hospital, University of British Columbia, Vancouver, Canada (D.V.F.); Department of Medical Imaging, Hematology and Clinical Oncology Ribeirão Preto Medical School, USP Ribeirão Preto, Brazil (M.H.N.B.); and Department of Orthopedic Surgery, University of Missouri Health Care, Columbia, Mo (M.H.N.B.).

The growing skeleton undergoes well-described and predictable normal developmental changes, which may be misinterpreted a as pathologic condition at imaging. Primary and secondary ossification centers (SOCs), which form the diaphysis and the epiphysis of long bones, respectively, are formed by endochondral and intramembranous ossification processes. During skeletal maturation, the SOCs may appear irregular and fragmented, which should not be confused with fractures, osteochondritis dissecans, and osteochondrosis. Read More

Comparative Evaluation of the Radiographic Parameters for Screening Early Blount Disease.

J Pediatr Orthop 2022 Apr;42(4):e343-e348

Department of Orthopaedic Surgery, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand.

Background: Radiographic findings in young children with physiological bowing sometimes difficult to distinguish from early Blount disease. However, early diagnosis of the disease is critical because of the poor treatment outcomes for Blount disease. In this study, we aim to evaluate the accuracy of the metaphyseal-diaphyseal angle (MDA) compared with the medial metaphyseal beak (MMB) angle for differentiating between physiological bowing and early Blount disease and to determine which parameter to adequately screen for the subsequent development of Blount disease.

Proton Density Fat Fraction Spine MRI for Differentiation of Erosive Vertebral Endplate Degeneration and Infectious Spondylitis.

Diagnostics (Basel) 2021 Dec 30;12(1). Epub 2021 Dec 30.

Department of Diagnostic and Interventional Radiology, University Hospital Bonn, Rheinische Friedrich-Wilhelms-Universität Bonn, 53127 Bonn, Germany.

Vertebral Modic type 1 (MT1) degeneration may mimic infectious disease on conventional spine magnetic resonance imaging (MRI), potentially leading to additional costly and invasive investigations. This study evaluated the diagnostic performance of the proton density fat fraction (PDFF) for distinguishing MT1 degenerative endplate changes from infectious spondylitis. A total of 31 and 22 patients with equivocal diagnosis of MT1 degeneration and infectious spondylitis, respectively, were retrospectively enrolled in this IRB-approved retrospective study and examined with a chemical-shift encoding (CSE)-based water-fat 3D six-echo modified Dixon sequence in addition to routine clinical spine MRI.

Osteochondrosis and other lesions in all intervertebral, articular process and rib joints from occiput to sacrum in pigs with poor back conformation, and relationship to juvenile kyphosis.

BMC Vet Res 2022 Jan 18;18(1):44. Epub 2022 Jan 18.

Norsvin SA, Storhamargata 44, 2317, Hamar, Norway.

Background: Computed tomography (CT) is used to evaluate body composition and limb osteochondrosis in selection of breeding boars. Pigs also develop heritably predisposed abnormal curvature of the spine including juvenile kyphosis. It has been suggested that osteochondrosis-like changes cause vertebral wedging and kyphosis, both of which are identifiable by CT. Read More

A History of Eponyms in Traction Apophysitises.

Bull Hosp Jt Dis (2013) 2021 ;79(3):200-204

Traction apophysitises are a well-known entity in the orthopedic world that are generally thought of as conditions of the pediatric population secondary to overuse and repetitive microtrauma. Many have been named for their original descriptors, and therefore the purpose of this review is to highlight the backgrounds of these physicians, pay tribute to those who came before, and standardize the definitions of these oft-used eponyms. Iselin's disease, Little League Elbow, Osgood-Schlatter disease, Sever's disease, and Sinding-Larsen-Johansson disease will be discussed in brief, followed by a historical background presenting the original description of the named author as well as a short biography.

Computed tomography findings in a cohort of 169 dogs with elbow dysplasia - a retrospective study.

BMC Vet Res 2021 Sep 6;17(1):296. Epub 2021 Sep 6.

Department of Preclinical Sciences and Infectious Diseases, Poznan University of Life Sciences, ul. Wołyńska 35, 60-637, Poznań, Poland.

Background: Canine elbow dysplasia (CED) is a complex developmental skeletal disorder associated with a number of pathological conditions within the cubital joint. Because CED is a heritable disease, it is important to identify and remove the affected animals from breeding. The first objective of this study was to describe the prevalence of medial coronoid process disease (MCPD) without (MCD) or with (FMCP) fragmented medial coronoid process, osteochondrosis (OC) and/or osteochondritis dissecans (OCD), ununited anconeal process (UAP), radio-ulnar incongruence (INC R-U) and humero-ulnar incongruence (INC H-U) in dogs with the use of CT imaging.
