Background:
Chronic hematogenous osteomyelitis often results from the improper treatment of acute hematogenous osteomyelitis. At present, there is lack of uniform standards for the treatment, and the clinical features of the disease are unclear. The purpose of this study was to explore the clinical efficacy and complications of chronic hematogenous tibia osteomyelitis treated with the induced membrane technique.
Methods:
A retrospective analysis of the chronic hematogenous tibia osteomyelitis patients in our department admitted from January 2013 to February 2014 and treated with the induced membrane two-stage surgical technique was performed. The defects were filled with antibiotic-loaded polymethyl methacrylate (PMMA) cement after radical debridement, and bone grafts were implanted to repair the defects after 6 to 8 weeks.
Results:
A total of 15 cases were admitted in this study, including 13 men and 2 women with a mean age of 34 years (6 to 51). The mean duration of bone infection was 142 months (3 to 361). All patients were cured with an average follow-up of 25 months (24 to 28). Radiographic bone union occurred in 5.3 months (3 to 8), and full weight bearing occurred in 6.7 months (4 to 10). No recurrence of infection was noted at the last follow-up. Two cases required repeated debridement before grafting due to recurrent infection. One patient had a small bone diameter due to insufficient grafting, and one patient had limitation of knee activity.
Conclusions:
The induced membrane technique for the treatment of chronic hematogenous tibia osteomyelitis is an effective and reliable method. Thorough debridement and wound closure at the first stage is essential for infection control as well as sufficient grafting at the second stage to ensure bone union.
Insights
The induced membrane technique effectively treats chronic hematogenous tibia osteomyelitis, leading to bone union and infection resolution. This method offers a reliable solution for complex bone infections.
Area of Science:
- Orthopedics
- Infectious Diseases
- Surgical Innovation
Background:
- Chronic hematogenous osteomyelitis often arises from inadequately treated acute cases.
- Current treatment standards are lacking, and clinical features remain unclear.
- This study addresses the need for effective management strategies for chronic tibia osteomyelitis.
Purpose of the Study:
- To evaluate the clinical efficacy of the induced membrane technique.
- To assess complications associated with this treatment for chronic tibia osteomyelitis.
- To provide insights into managing this challenging bone infection.
Main Methods:
- Retrospective analysis of 15 patients with chronic hematogenous tibia osteomyelitis (Jan 2013-Feb 2014).
- Two-stage surgical technique involving radical debridement and antibiotic-loaded polymethyl methacrylate (PMMA) cement.
- Delayed bone grafting (6-8 weeks) to repair bone defects.
Main Results:
- All 15 patients achieved cure with a mean follow-up of 25 months.
- Average time to radiographic bone union was 5.3 months; full weight-bearing achieved in 6.7 months.
- Low complication rate: two cases needed repeat debridement, one had insufficient grafting, one experienced knee stiffness.
Conclusions:
- The induced membrane technique is an effective and reliable treatment for chronic hematogenous tibia osteomyelitis.
- Thorough debridement and wound closure are critical for initial infection control.
- Adequate bone grafting in the second stage is crucial for successful bone union.
