An Unrecognized Ligament and its Ossification in the Craniocervical Junction: Prevalence, Patient Characteristics, and Anatomic Evidence.

Clin Orthop Relat Res 2021 Mar 15. Epub 2021 Mar 15.

B. Wu, W. Cui, T. Rong, D. Sang, B. Xiao, D. Wang, J. Zhang, B. Liu, Department of Orthopaedic Surgery, Beijing Tiantan Hospital, Capital Medical University, Beijing, China.

Background: In the craniocervical junction, the ligaments between the anterior foramen magnum and the anterior arch of the atlas are not well defined, and ossification of the ligaments in this region has rarely been reported. Characterizing the anatomy and ossification of these ligaments may help in the diagnosis and treatment of disorders in this region.

Questions/purposes: (1) What is the prevalence of an unrecognized ossification at the craniocervical junction in patients with cervical spine disorders, and what are the patient characteristics associated with this ossification? (2) Do patients with this ossification have a greater risk of ossification of other structures at the craniocervical junction or cervical spine? (3) Is there an unreported ligament at this ossified site?

Methods: We conducted a retrospective study of 578 hospitalized patients who underwent CT for cervical spine disorders between January 2016 and July 2020. Read More

Multidisciplinary team obviates biopsy in most patients with diffuse parenchymal lung diseases-A retrospective study from India.

Clin Respir J 2021 Mar 15. Epub 2021 Mar 15.

Department of Pulmonology and Internal Medicine, Mazumdar Shaw Medical Center, Narayana Health City, Bengaluru, India.

Introduction: The inflammation and fibrosis in diffuse parenchymal lung diseases (DPLDs) in varied proportions give rise to different patterns in radiology and histopathology. The radiological pattern on CT of the thorax most often allows us to make a diagnosis with varying levels of confidence, to optimize management. With a multidisciplinary team bringing the strengths of their individual domains of knowledge, clinical, radiological, histopathological, and in many cases rheumatological, the level of confidence in making this diagnosis increases, often to the stage where the diagnosis is most often right, is concordant with the diagnosis achieved at histopathology and therefore obviates the need for lung biopsy which carries its own costs and risks of complications.
