Stifle arthrodesis in dogs using semi-circular saw: Cadaveric study

Area of Science:

• Veterinary Surgery
• Canine Orthopedics

Background:

• Stifle arthrodesis is a surgical procedure to fuse the stifle joint in dogs.
• Developing improved surgical techniques is crucial for successful outcomes.

Purpose of the Study:

• To present a novel surgical technique for canine stifle arthrodesis.
• To evaluate the feasibility and outcomes of using a semicircular saw for tibial and femoral ostectomies via a medial approach.

Main Methods:

• Ten canine cadaver pelvic limbs underwent stifle arthrodesis.
• Pre- and post-operative radiography was performed for planning and angular measurements.
• A medial approach was used for semicircular saw ostectomies of the tibia and femur.
• Landmarks were identified for precise bone cuts.

Main Results:

• The medial approach provided good visualization of intra-articular structures.
• Dome ostectomies allowed for fragment alignment and angulation adjustment.
• The mean final knee joint angulation was 134.7 ± 11 degrees.
• One instance of iatrogenic injury (long digital extensor tendon rupture) occurred.

Conclusions:

• The described technique offers a viable method for canine stifle arthrodesis.
• The medial approach and semicircular saw facilitate precise bone preparation.
• Further studies are warranted to assess clinical applications and long-term outcomes.
