Summary
The Gamma Nail significantly reduces surgery time, blood loss, and complications for sub-trochanteric fractures compared to traditional angular implants. This study confirms its superiority for improved patient outcomes and faster recovery.
Area of Science:
- Orthopedic surgery
- Traumatology
- Biomaterials in medicine
Background:
- Sub-trochanteric fractures present significant treatment challenges.
- Traditional osteosynthesis methods often lead to prolonged recovery and complications.
Purpose of the Study:
- To evaluate the superiority of the Gamma Nail for treating sub-trochanteric fractures.
- To compare the Gamma Nail with angular implant techniques.
Main Methods:
- A comparative study of 80 patients with sub-trochanteric fractures.
- Group I (40 patients) received angular implants; Group II (40 patients) received Gamma Nails.
- Comparison based on operative duration, blood loss, ambulation, radiological healing, and complications.
Main Results:
- Gamma Nail group showed shorter operative duration (1 hr vs 3 hrs) and less blood loss (40% vs 90% transfusion rate).
- Immediate weight-bearing was possible with Gamma Nails versus 3 months for angular implants.
- Radiological bone healing averaged 2 months with Gamma Nails versus 3.5 months with angular implants.
- Complication rates were significantly lower with Gamma Nails (7.5% vs 30%).
Conclusions:
- The Gamma Nail demonstrates clear superiority over angular implants for sub-trochanteric fracture treatment.
- Reduced operative time, blood loss, and complication rates highlight the benefits of the Gamma Nail.
- The Gamma Nail facilitates faster patient recovery and improved outcomes.
