[Treatment of femoral trochanteric fracture with intramedullary interlocking nailing: a report of 32 cases]

Area of Science:

• Orthopedic surgery
• Biomedical engineering
• Trauma management

Context:

• Femoral trochanteric fractures are common injuries requiring stable fixation.
• Existing intramedullary nails have limitations that necessitate improvement.
• The gamma locking nail served as a reference for developing a new system.

Purpose:

• To introduce an improved intramedullary interlocking nail and its surgical instrumentation.
• To evaluate the efficacy and safety of this novel fixation system for femoral trochanteric fractures.

Summary:

• 32 cases of femoral trochanteric fractures were treated using the improved intramedullary interlocking nail system.
• Patients experienced early mobilization (6-13 days post-op) with no implant failures or infections.
• Follow-up of 29 cases (5-19 months) showed complete fracture healing and functional recovery, with minor complications in two cases.

Impact:

• The intramedullary interlocking nail offers superior strength and stability for treating all types of femoral trochanteric fractures.
• This system aligns with biomechanical principles, providing an effective surgical treatment option.
• The improved nail design contributes to better patient outcomes and reduced complication rates in fracture management.
