“…These variations in C1 do not typically affect the stability of the C1 joints and are mostly asymptomatic. However, Pacheco et al (2) propose a new classification of C1 abnormalities, continuing Currarino's classification and highlighting two types. Type A is characterized by hypertrophy of the posterior tubercle, where a fourth ossification center is present, alongside with premature fusion of the lateral sections of the posterior arch.…”

Aim: In this intriguing review, the authors dive into the complex world of atlas stenosis and its clinical impact on cervical myelopathy. The authors shed light on the origins of atlas stenosis, highlighting how congenital abnormalities of the atlas are a result of failures in embryological development. Furthermore, diagnosis and treatment methods are described.Materials and method: Utilizing a detailed search of the literature in the PubMed database, the authors have compiled a comprehensive analysis of the anatomical and biological basis of this condition. After applying the exclusion criteria, 25 papers were deemed appropriate for the present review.Results: With the help of computed tomography (CT) and magnetic resonance imaging (MRI) scans, diagnosis becomes possible, but the authors emphasize the importance of using special tests for a more accurate assessment. When it comes to treatment, surgical decompression with laminectomy or laminoplasty is the suggested approach. This highlights the severity of atlas stenosis and the need for intervention to alleviate the symptoms and prevent further neurological damage. What sets this review apart is its focus on the clinical profile of atlas stenosis. The authors discuss how the obstruction of cerebrospinal fluid flow can lead to neurological disorders and headaches. This sheds light on the broader impact this condition can have on patients' lives beyond simply the anatomical implications. Conclusion:In the conclusion, the authors emphasize the susceptibility of the spinal cord to injuries even with mild mechanical pressure or instability due to aging in patients with atlas stenosis. Additionally, the instabilities caused by anatomical abnormalities of the atlas further highlight the importance of considering atlas stenosis in cases of cervical trauma. Overall, this review provides a fascinating insight into the connection between atlas stenosis and cervical myelopathy. By exploring the anatomical, biological, diagnostic, and treatment aspects of this condition, the authors have contributed to the understanding of this complex and often overlooked topic.

“…Despite its low prevalence, atlas deformity associated with spinal cord compression constitutes a potentially devastating condition, which may lead to quadriplegia and even death (1,2). In 1989, Sawada et al (3) first reported the use of C1 laminectomy (C1L) for a case of canal stenosis at the level of the atlas.…”

Background: Developmental atlantal stenosis with myelopathy (DASM) in adults is a rare disease that only sporadic cases have been reported over the years. C1 laminectomy (C1L) is one of the most common operations for its treatment. However, as an open surgery, it has shortcomings such as large trauma and slow postoperative rehabilitation, and minimally invasive spine surgery (MISS) offers alternative treatment options with advantages. MISS instruments expand the technical capabilities of surgeons, which allows safer and more effective therapeutics for difficult and complicated diseases. This case report presents a new minimally invasive approach; percutaneous full endoscopic C1 laminectomy (PFEC1L), for the treatment of DASM, and to consolidate the current literature on the condition to summarize its etiologies, clinical manifestations, diagnostic criteria, surgical management, and prognoses.
