Kiran Nandivada’s Stuck Blade in a Grinder Jar Degenerative Cascade by LSTV at L5-S1

Open Journal of Orthopedics 2024年第1期14卷 12-21页

作者： Venkata Satya Kumar Kiran Nandivada Nadavinamani Shivanand Raghavendra Nandivada Nikhil Bharadwaja Moola Sohith Mahadeva Reddy Ahmed Usama rizvi Nandivada Ortho Spine Surgeon & Rheumatologist Abu Dhabi United Arab Emirates Senior Orthopedic Surgeon & Rheumatologist Abu Dhabi United Arab Emirates General Practitioner Visakhapatnam India Department of Medicine Kamineni Institute of Medical Sciences Telangana India Department of Medicine Tbilisi State Medical University Tbilisi Georgia

Background: Mario Bertolotti, (1917) described LSTV-Lumbar spinal transitional vertebra as Bertolotti Syndrome a century ago and associated low back pain with it. Yet, it needs to be given significance in general orthopaedic practice even now, and radiologists underreport it. LSTV is a congenital anatomical anomaly that Castellvi classified into four varying types. Purpose: I titled this phenomenon “Kiran Nandivada’s stuck blade in a grinder jar degenerative cascade by LSTV at L5-S1” to clearly explain how an abnormal mega-transverse apophysis with its various variations affects the weight-bearing mechanics as the L5-S1 which is a vital junction where the maximum body weight is directed into both the sacroiliac joints and if a transitional vertebra occurs it becomes detrimental and abnormally redirects the load-bearing forces and leads to a progressive degenerative cascade both proximally and distally. As the L5 vertebral rotations and other movements of flexion, extensions, lateral flexion are stuck like a bent grinder blade, the other areas of the region are damaged progressively as the pelvis, just like the grinder motor tries to move it, resulting in overheating and maybe even a burnout results in the form of facet arthritis, disc degeneration in the normal disc above, the transitional disc at L5-S1, foraminal osteophytes causing radiculopathy, sacroiliac joint arthritis. Material and Methods: Around 200 X-rays of children and adults with this congenital anomaly have been studied between 2020 and 2023. This is a retrospective study. Results: 1) Our study showed an Increased incidence of LSTV at 15%. 2) Patients ranged from asymptomatic, atypical lumbago to classical lumbago with sciatica and claudication. Findings supported facet and sacroiliac joint arthritis and the pain, relieved with physiotherapy, posture corrections, weight reduction, and lifestyle precautions, negating the need for local steroid injections, radiofrequency ablation or surgical excision as

Various Aetiologies of Non-Traumatic Coccydynia Cause Pain in the Posterior Sacrococcygeal Leg of the Pelvic Tripod: A Burden on the Healthcare Sector

引用

Open Journal of Orthopedics 2024年第7期14卷 334-353页

作者： Kumar Satya Nandivada Venkata Kiran Nadavinamani Shivanand Raghavendra Oommen Elsy Biju Bharadwaja Nikhil Nandivada Nandivada Vaishnavi rizvi Usama Ahmed Krushi Orthopaedic Welfare Society Research Wing Visakhapatnam India

Introduction: Coccydynia, television disease, and coccygodynia are the different names given to this disabling disease, which can become chronic. It was described by Simson in 1859. Coccydynia means pain at the end of the vertebral column. Non-traumatic coccydynia is a diagnosis, which is never straightforward like traumatic coccydynia because the onset is unclear, and both the patient and the unaware clinician face many challenges in treating it on time and with accuracy. Coccyx was likened to a cuckoo bird’s beak as a curved bone of fused 3 to 5 vertebrae with remnant disc material in some rare cases, unfused segments, linear scoliosis or subluxations and deformities. Stress X-rays of the coccyx in the antero-posterior and lateral views in standing and sitting reveal the “Dynamic Instability” due to congenital coccygeal morphological, pathological and mechanical variations. Material and Methods: This is a complex study having retrograde data collected from online publications from various databases, like PubMed, Embase, and Cochrane Library and also antegrade data collected from 100 patients with their consent from patients in Adam and Eve Specialised Medical Centre-based at Abu Dhabi, UAE and data was processed in the research centre of Krushi Orthopaedic Welfare Society based in India between 2014-2024 following all guidelines of Helsinki and approved by the ethics board of Krushi Orthopaedic Welfare Society. Clinical Presentation: The coccyx is painful, with aches, spasms, and an inability to sit. This affects daily activities without any particular date of onset. The onset remains insidious for the non-traumatic variety of coccydynia. Aetiology and Patho Anatomy: Non-traumatic coccydynia can be caused by a myriad of reasons, like congenital morphological variations, acquired dynamic instabilities, and hidden trauma remaining quiescent to re-surface as a strain-induced pain. Radiological Presentations: Unless clarity is focused on these coccygeal views, the err
