Dear Editor,

We appreciate the letter from Prof. A. Goel, whose team had reported a patient with congenital basilar invagination after odontoidectomy in the year 1994, and the stability reconstruction was performed by a double compression stainless steel radio-ulnar fixation plate with screws place to the clivus and the body of the cervical vertebra [1]. For the anterior occipitocervical reconstruction, except for the above fixation method, the modified titanium mesh was also applied [2]. However, for the clival screw fixation, the anatomy of the clivus was unclear; furthermore, there was no specific instrumentation for the craniovertebral region anteriorly. Then, we conducted series anatomic studies for the clival screw placement [3]. Based on those anatomic data, a novel clivus plate fixation system specific to craniovertebral region was developed, which was biomechanically prior to the conventional fixation techniques [4]. Therefore, there are innovations in our series of works as stated above, and that will lay a foundation for the clinical application. Surely, in our previous studies, the researches of Dr. Goel’s team and studies related to the method of the modified titanium mesh were also quoted.
