Short versus long intramedullary nails for intertrochanteric hip fracture: Meta-analysis

Area of Science:

• Orthopedic surgery
• Traumatology
• Biomaterials engineering

Background:

• Intertrochanteric hip fractures are common, particularly in elderly patients.
• Intramedullary nails are a standard treatment for these fractures.
• The choice between short and long intramedullary nails is debated.

Purpose of the Study:

• To compare the efficacy and safety of short versus long intramedullary nails for treating intertrochanteric hip fractures.
• To analyze reoperation rates, peri-implant fractures, surgery time, blood loss, and functional outcomes.

Main Methods:

• Systematic review and meta-analysis of cohort studies and randomized clinical trials.
• Methodological quality assessed using the Newcastle-Ottawa Scale.
• Data synthesized using Review Manager 5.4 with heterogeneity analysis (I² test) and fixed-effects model where appropriate.

Main Results:

• Twelve studies were included in the meta-analysis.
• The short nail group demonstrated a significantly lower reoperation rate (OR 0.58).
• Longer surgery time and greater blood loss were observed with long nails, with no significant difference in peri-implant fracture rates or functional outcomes.

Conclusions:

• Short intramedullary nails appear to be a safer and more efficient option for intertrochanteric hip fractures.
• Long nails were associated with increased surgical burden (time, blood loss) and higher reoperation rates.
• Further research may focus on patient selection criteria for optimal nail choice.
