Multiple Intramedullary and Skewer Pin Fixation for Complex Humeral and Femoral Fractures in Cats and Small-Breed...

Area of Science:

• Veterinary Orthopedics
• Small Animal Surgery

Background:

• Complex fractures in cats and small dogs present surgical challenges.
• Intramedullary and skewer pin fixation is an alternative fixation strategy.

Purpose of the Study:

• To evaluate clinical and radiographic outcomes of multiple intramedullary and skewer pin fixation.
• To assess this technique in complex humeral and femoral fractures in cats and small-breed dogs.

Main Methods:

• Retrospective study of 32 client-owned animals.
• Fractures stabilized using multiple intramedullary Steinmann pins with optional skewer pins and/or cerclage wires.
• Radiographic evaluation for alignment, healing time, and walking outcomes recorded.

Main Results:

• 81% of fractures achieved anatomical alignment.
• Mean healing time was 3.3 months.
• 75% of cases had excellent functional outcome (Grade 1), and 19% had good outcome (Grade 2).

Conclusions:

• Multiple intramedullary and skewer pin fixation provides satisfactory stabilization and functional recovery.
• This technique is effective for complex humeral and femoral fractures in cats and small-breed dogs.
• Careful application and postoperative management are crucial for success.
