🔍 Key Findings

• Fluoroscopically guided normograde metabone pinning (FGNMP) was used to treat 17 animals (15 dogs and 2 cats) with 57 metabone fractures, including various fracture configurations (short-oblique body, physeal, and comminuted).
• All 57 fractures were stabilized using intramedullary pins via FGNMP. The study exclusively focused on pin fixation and did not include screws or combined fixation techniques.
• Median surgical time was 54 minutes (range 26–99 min), indicating efficient procedural execution.
• Radiographic bone union was achieved in all fractures, with a median time to union of 6 weeks (range 4–12 weeks). Union was confirmed in all initially non-united fractures on follow-up.
• No major complications were reported. A single pressure sore at the olecranon resolved uneventfully, and no pin migration or osteomyelitis was observed.
• Pin extensions were noted radiographically (e.g., 42% distal subchondral overextension), but were not associated with clinical problems.
• Fluoroscopic guidance improved implant accuracy and preserved soft tissue, enabling effective fracture alignment and stabilization using this minimally invasive osteosynthesis (MIO) approach.
• The authors concluded that FGNMP is an effective, safe, and minimally invasive method for a variety of metabone fracture types, yielding quick recovery, fast healing, and good to excellent long-term functional outcomes in all 17 cases.
