RADIOLOGICAL EVALUATION OF CRANIOVERTEBRAL JUNCTION ANOMALIES
Journal Title: Journal of Evidence Based Medicine and Healthcare - Year 2015, Vol 2, Issue 35
Abstract
Detailed discussions of the CVJ are conspicuously absent in many standard textbooks and chapters addressing the skull or cervical spine, since it lies in between these regions. CVJ anomalies are common in India subcontinent. OBJECTIVES: To outline the normal anatomy and various abnormalities of craniovertebral junction. To evaluate the most common developmental and acquired craniovertebral junction abnormalities. CRANIOMETRY AND DIAGNOSIS: Radiological evaluation of CVJ requires identification of only a few anatomic structures. Over the years multiple lines, planes and angles have been described for assessment of CVJ relationship, initially with radiography and later with polytomography. Two lines have remained particularly useful for evaluation of CVJ relationship with virtually any imaging modality: the chamberlain`s line and weckenheim’s clivus base line. Two angles also continue to be useful: the welcher basal angle and atlanto occipital joint axis angle. PATIENTS AND METHODS: The prospective study of craniovertebral junction anomalies was carried out at Kurnool medical college, Governament general hospital Kurnool from NOV 2012 to AUG 2014. The patients are subjected to clinical evaluation and radiological evaluation. OBSERVATIONS AND RESULTS: In our study there is male predominance with male to female ratio of 2:1.Majority of patients are in the age group of 11-40 (73.26%). The commonest symptom seen is weakness of extremities (70%) with associated numbness (50%). On clinical examination pyramidal tract involvement noticed in 70% of cases. Basilar invagination is the most common followed by Atlantoocoipital assimilation (40%) and AAD (30%). CONCLUSION: Computed tomography and magnetic resonance imaging are invalvable adjuncts to the plain radiographs in the evaluation of the craniovertebral junction anomalies. Chamberlain’s line and McGregor line are the most commonly applied craniometric measurements.
