Department of Endocrinology and Metabolism, Institute of Endocrinology, NHC Key Laboratory of Diagnosis and Treatment of Thyroid Diseases, The First Affiliated Hospital of China Medical University, Shenyang, P. R. China.

Background: Osteogenesis imperfecta (OI) is a heterogeneous connective tissue disorder characterized by increased bone fragility and a series of extraskeletal manifestations. Approximately 90 % of OI cases are caused by type I collagen variants encoded by the collagen type I alpha 1 (COL1A1) or type I alpha 2 (COL1A2) gene. Lumbar Scheuermann's disease is an atypical type of Scheuermann's disease accompanied by Schmorl's nodes and irregular endplates but without pronounced kyphosis. Read More

Insights Imaging 2021 Feb 11;12(1):14. Epub 2021 Feb 11.

Neuroradiology Department, IRCCS Mondino Foundation, Pavia, Italy.

Objective: To promote a better radiological interpretation of spine degeneration, a consistent standardization of the acquisition, interpretation and description of Magnetic Resonance Imaging (MRI) l findings.

Materials And Methods: In order to achieve this objective, a consensus among experts in imaging of degenerative spine disease (DSD) from Italian radiological societies (SIRM-Italian Society of Radiology, AINR-Italian Association of Neuroradiology) was achieved. The representatives of the Italian inter-societal working group examined the literature produced by European/American task forces on optimizing the study sequences, classification of degenerative disc changes, spondylo-arthrosis, osteochondrosis, synovial and ligament pathologies of the spinal column, and on canal and foraminal stenosis.

The Medial Elevation Osteotomy for Late-presenting and Recurrent Infantile Blount Disease.

J Pediatr Orthop 2021 Feb;41(2):67-76

Department of Orthopaedic Surgery, School of Clinical Medicine, University of KwaZulu-Natal, KwaZulu-Natal, South Africa.

The dimensions of "failed back surgery syndrome": what is behind a label?

Acta Neurochir (Wien) 2021 01 1;163(1):245-250. Epub 2020 Sep 1.

Department of Neurosurgery, Medical School Hannover, MHH, Hannover, Germany.

Background: The term failed back surgery syndrome (FBSS) has been criticized for being too unspecific and several studies have shown that a variety of conditions may underlie this label. The aims of the present study were to describe the specific symptoms and to investigate the primary and secondary underlying causes of FBSS in a contemporary series of patients who had lumbar spinal surgery before.

[Multidomain approach in chronic non-specific back pain patient's treatment].

Zh Nevrol Psikhiatr Im S S Korsakova 2020 ;120(7):113-120

Sechenov First Moscow State Medical University (Sechenov University), Moscow, Russia.

The concept of chronic nonspecific back pain (CNBP) as a pathology of the spine (osteochondrosis, spondylosis, intervertebral disc herniation, facet syndrome) is extremely outdated and has not justified itself, first of all, from the therapeutic view point. Numerous studies, including meta-analyzes and systematic reviews, have convincingly shown the ineffectiveness of the methods of CNBP treatment, aimed only at solving the problems of the spine itself and / or surrounding tissues. A substantial amount of special imaging studies have proven the dissociation between morphological vertebral changes and the clinical picture of pain. Read More

Department of Diagnostic Radiology, St. Vincent's Medical Center at Hartford Healthcare, 2800 Main Street, Bridgeport, CT 06606, USA.

Osteochondroses is a well-known entity and typically affecting immature skeleton with few common locations involved are femoral head epiphysis, tibial tubercle apophysis, calcaneal apophysis, humeral capitellum and anterior vertebral end plates. We report a rare case of osteochondroses showing avascular necrosis involving metacarpal heads known as Dieterich disease, involving the head of the third metacarpal and probably the first case with a history of rock climbing as an etiology. Chronic repetitive microtrauma plays a significant role in the disease, as is seen in our patient. Read More
