Hypothesis
Can 3D-printed porous prostheses combined with flap repair effectively treat infectious tibial bone defects?
Conclusion
The use of 3D-printed porous titanium prostheses combined with flap soft-tissue repair for the treatment of infectious tibial bone defects did not increase the rate of infection recurrence and provided good functional recovery.
Supporting Evidence
- 7 out of 13 patients achieved radiographic healing without intervention.
- Two patients developed prosthesis-related complications requiring revision surgery.
- None of the patients showed a recurrence of infection at the last follow-up.
Takeaway
Doctors used special 3D-printed parts to help fix broken bones in people's legs, and it worked well without causing more infections.
Methodology
A retrospective study of 13 patients treated with a two-stage approach involving debridement, flap repair, and implantation of 3D-printed prostheses.
Limitations
The study was retrospective with a small sample size and lacked comparative analysis with other methods.
Participant Demographics
12 males and 1 female, mean age 48.7 years.
