Correction of pes varus deformity in a Miniature Dachshund by true spherical osteotomy with a dome saw blade.

Abstract

CASE DESCRIPTION: A 6-month-old male Miniature Dachshund was referred for examination and correction of a unilateral pes varus deformity. CLINICAL FINDINGS: Clinical examination and diagnostic imaging revealed varus, procurvatum, and internal torsion of the distal aspect of the left tibia causing intermittent lameness. TREATMENT AND OUTCOME: True spherical osteotomy performed with a dome-shaped saw allowed correction of the deformity in 3-D, and orthogonal internal plate fixation provided stabilization. No intraoperative or immediate postoperative complications developed. Outcome as judged by the clinician and the owners was satisfactory 2 weeks after surgery and excellent at each subsequent assessment. The patient remained free of clinical signs at the last follow-up 30 months after surgery. CLINICAL RELEVANCE: To the authors' knowledge, this case represented the first time a true spherical osteotomy was used to correct a pes varus deformity in a canine patient.
