Title: Partial ostectomy of the dens to correct atlantoaxial subluxation in a pony. Author: Cillán-Garcia E, Taylor SE, Townsend N, Licka T. Journal: Vet Surg; 2011 Jul; 40(5):596-600. PubMed ID: 21395622. Abstract: OBJECTIVE: To report a surgical technique that allows decompression and anatomic re-alignment for management of subluxation of the atlantoaxial articulation. STUDY DESIGN: Clinical report. ANIMALS: Four-year-old Welsh Section B pony gelding. METHODS: Attempts at closed reduction of subluxation of the atlantoaxial articulation under general anesthesia were unsuccessful, so a ventral surgical approach allowing partial ostectomy of the dens of the axis was used to facilitate reduction. RESULT: Recovery from surgery was uneventful and the pony remained comfortable without neurologic deficits. Both neck stiffness and ataxia resolved. Radiographic examination at 5 days and 6 months postoperatively showed normal anatomic position of the dens of the axis and stabilization of the atlantoaxial joint. CONCLUSION: Partial ostectomy of the dens using a ventral approach can be used to facilitate reduction of atlantoaxial subluxation.[Abstract] [Full Text] [Related] [New Search]
