Orthogonal double plate fixation for long bone fracture nonunion

Area of Science:

• Orthopedic surgery
• Trauma surgery
• Biomechanics

Background:

• Long bone diaphyseal fracture-nonunion presents a significant clinical challenge.
• Achieving fracture healing requires both biological viability and mechanical stability.
• Previous treatments may fail, necessitating revision strategies.

Purpose of the Study:

• To evaluate the efficacy of orthogonal double plating for treating recalcitrant long bone diaphyseal fracture-nonunions.
• To assess surgical management with limited periosteal stripping and soft tissue dissection.
• To determine the biomechanical soundness and clinical outcomes of this technique.

Main Methods:

• Retrospective analysis of 22 patients treated with double plating for long bone nonunion (2007-2009).
• Surgical technique involved primary plate fixation followed by a second plate at 90 degrees, with minimal soft tissue dissection.
• Autologous bone graft or substitute used in most cases; infection management included culture-specific antibiotics.

Main Results:

• All 22 patients achieved union, with an average healing time of 5.8 months.
• One patient required repeat double plating for successful union.
• Positive tissue cultures in 11 patients; no hardware failure reported. Functional scores (LEFS, DASH, SF-12) indicated positive outcomes.

Conclusions:

• Orthogonal double plating offers a biomechanically stable and effective solution for long bone fracture nonunion.
• Successful outcomes are contingent upon addressing biological factors, particularly infection eradication.
• This technique demonstrates reasonable results in complex fracture nonunion cases.
