Feline Shoulder Arthrodesis Using 3D-printed Patient-specific Guides

This case series aims to explore the application of 3D-printed patient-specific guides (PSG) in feline shoulder arthrodesis, addressing the scarcity of literature on this procedure in cats. The primary objectives include assessing the feasibility, accuracy, and outcomes of the procedure in four feline cases.The study employed a retrospective analysis of cases involving feline shoulder arthrodesis performed using PSG. Surgical planning utilized CAD-based techniques, and 3D-printed guides were created for precise osteotomies and implant placement. Follow-ups included radiographic assessments, re-examinations, and owner-reported outcomes.Four feline cases with distinct shoulder issues were successfully treated using PSG. Postoperative management, radiographic evaluations, and long-term follow-ups revealed positive outcomes in terms of limb function and patient activity. The study demonstrates the potential of PSG in achieving accurate humeroscapular alignment in feline shoulder arthrodesis.This case series highlights the clinical significance of PSG in enhancing the precision of humeroscapular alignment during feline shoulder arthrodesis. The positive outcomes observed in various shoulder pathologies suggest that this technique could contribute to improved surgical outcomes.
