Summary
Surgical treatment using external fixators effectively achieved bone healing in eight patients with infected humerus nonunion. This approach led to consolidation in all cases, demonstrating its potential for managing complex fractures.
Area of Science:
- Orthopedic surgery
- Trauma management
- Bone infection treatment
Background:
- Infected nonunion of the humerus presents a significant challenge in orthopedic surgery.
- Previous instrumentation often fails, necessitating revision surgery.
- Delayed treatment can complicate fracture healing and increase infection risk.
Purpose of the Study:
- To evaluate the efficacy of surgical debridement and external fixation for infected humerus nonunion.
- To assess bone consolidation rates and functional outcomes in patients treated with external fixators.
- To report on complications and recovery following this treatment protocol.
Main Methods:
- Eight patients with infected humerus nonunion underwent surgical intervention.
- Procedures included instrumentation removal, debridement or resection, and external fixation (monoaxial or circular).
- Mean time from trauma to treatment was 13 months.
Main Results:
- All eight patients achieved bone consolidation after an average of 5.5 months.
- Long-term follow-up (mean 18 months) showed successful outcomes.
- Two patients experienced temporary radial nerve palsy, with full recovery within 3 months.
Conclusions:
- Surgical management combining debridement and external fixation is a viable option for infected humerus nonunion.
- External fixation provides stable compression, promoting fracture healing.
- The treatment protocol demonstrates a high success rate with manageable complications.
