Clinical Report: Suprapatellar IMN vs MIPO for Distal Tibial Fractures

Overview

This study compares suprapatellar intramedullary nailing (IMN) and minimally invasive plate osteosynthesis (MIPO) for treating distal tibial fractures. IMN demonstrated advantages in operative time, blood loss, and early functional recovery, while MIPO showed better alignment control.

Background

Distal tibial fractures are prevalent and challenging due to limited soft tissue coverage and complex biomechanics. Surgical intervention is essential for effective treatment, with IMN and MIPO being the primary fixation techniques. Understanding the comparative effectiveness of these methods is crucial for optimizing patient outcomes.

Data Highlights

Key Findings

• IMN resulted in shorter operative time, less blood loss, and smaller incisions compared to MIPO.
• At 1 and 3 months, IMN showed superior functional outcomes (VAS, AOFAS, Lysholm scores, and knee ROM).
• Time to union was significantly shorter in the IMN group (21.8 weeks) compared to MIPO (23.7 weeks).
• Anterior knee pain was more common in the IMN group, while incision-related complications were more frequent in the MIPO group.
• Fracture classification, surgical method, operative time, and BMI were identified as independent risk factors for complications.

Clinical Implications

Surgeons should consider the advantages of IMN for early recovery and fracture healing when treating distal tibial fractures. However, MIPO may be preferable for cases requiring better alignment control. Individualized surgical strategies are essential based on patient-specific factors.

Conclusion

Both IMN and MIPO are effective for treating distal tibial fractures, with IMN favoring early recovery and MIPO offering better alignment control. The choice of technique should be tailored to the individual patient's needs.
