ABSTRACT:

Background: Anomalies of craniovertebral junction (CVJ) are of interest both to an anatomist as well as to the clinicians because many of these deformities produce clinical symptoms. The stability of this CVJ depends largely on the morphometric parameters of the occipital condyles (OCs).  Most of the surgical approaches such as, the lateral trans-jugular approach, trans-tubercular approach and transcondylar approach require resection of the condyles.

Materials and methods:  The measurements of 30 occipital condyle length, width, height, Size and the anterior and posterior intercondylar distances, Distance between the anterior tip of OC & Basion, Distance between the posterior tip of OC & Opisthion, Anterior intercondylar distance (AID), Posterior intercondylar distance (PID), non-metric parameters including Shape was done. Results: Mean length, width and height of the occipital condyle were found to be 23.2, 12.39   and 9.16 mm on the right and 23.43, 12.31 and 8.95 mm on the left respectively. The anterior and posterior intercondylar distances were 21.28 and 40.61 mm respectively.

Conclusion: The occipital condyles are integral part of neck and base of the skull. In the present study an effort was made to measure various parameters related to occipital condyle. The data may be used as a morphometric data base for posterior and lateral approaches to the craniovertebral junction by neurosurgeons and orthopaedicians.

KEY WORDS:   Occipital condyles, morphometry, Index, Craniovertebral junction.
