Abstract:
Intramedullary infection is a challenging problem and treatment usually includes removal of infected hardware and reaming of the medullary canal. We describe a new technique for canal débridement and evaluate its infection control rate in treating osteomyelitis of the tibia and femur. We retrospectively reviewed 11 patients with posttraumatic osteomyelitis of the tibia (n = 8) or femur (n = 3). Surgery included débridement, implant removal, and reaming of the medullary canal with a new device that allows reaming under simultaneous irrigation and aspiration. At a minimum followup time of 6 months (mean, 13 months; range, 6-23 months), we observed no recurrence of infection. Complications included one partial loss of a flap, one refracture of a tibia after an automobile versus pedestrian accident, and external fixator pin tract infections in one patient. These preliminary data suggest the new reaming device may be a useful adjunct for débriding intramedullary infections of the tibia and femur.
Insights
A novel reaming device effectively cleared intramedullary infections in tibia and femur osteomyelitis patients. This technique showed promising results, with no infection recurrence in a 6-month follow-up.
Area of Science:
- Orthopedic Surgery
- Infectious Disease Management
- Biomedical Engineering
Background:
- Intramedullary infections pose significant treatment challenges.
- Current standard treatments involve hardware removal and canal reaming.
- Effective débridement is crucial for eradicating bone infections.
Purpose of the Study:
- To introduce and evaluate a new reaming device for intramedullary canal débridement.
- To assess the infection control rate of this technique in posttraumatic osteomyelitis.
- To determine the efficacy of simultaneous irrigation and aspiration during reaming.
Main Methods:
- Retrospective review of 11 patients with tibial or femoral osteomyelitis.
- Surgical débridement, infected implant removal, and canal reaming using a novel device.
- The device enabled simultaneous irrigation and aspiration during the reaming process.
Main Results:
- No recurrence of infection was observed in any patient at a minimum 6-month follow-up (mean 13 months).
- Preliminary data indicate a high infection control rate.
- Complications were limited and included flap loss, refracture, and pin tract infections.
Conclusions:
- The new reaming device appears to be a valuable adjunct for débriding intramedullary infections.
- This technique shows potential for improved outcomes in treating tibial and femoral osteomyelitis.
- Further research with larger cohorts is warranted to confirm these findings.
