Summary
Objective: To report the use of computeraided design software for virtual surgical planning
and design of three-dimensional printed patient-specific osteotomy and reduction guides
for facilitation of bilateral shoulder arthrodesis in a dog.
Methods: A three-year-old male entire Pekinese was presented unable to walk due to bilateral
severe medial shoulder instability. Computed tomographic data was processed to yield
three-dimensional mesh representations of the humeri and scapulae which could be manipulated
in computeraided design software. Key virtual surgical planning steps included joint
realignment, osteo-tomies of the glenoid and humeral head, and reduction. Virtual
osteotomy and reduction guides were designed, three-dimensionally printed, and used
intra-operatively.
Results: Appropriate alignment, reduction and fixation of the humeri and scapulae were achieved
bilaterally. The patient regained the ability to walk unassisted after two weeks and
was subsequently able to exercise normally without lameness.
Clinical significance: Patient-specific, three-dimensional printed osteotomy and reduction guides facilitated
accurate bilateral shoulder arthrodeses.
