Summary

Allogeneic bone nails offer rigid fixation for articular fractures, promoting healing within 1-3 months with good biological compatibility. This material is fully absorbed, eliminating the need for a second surgery.

Background:

Articular fractures present challenges in achieving stable fixation and preserving joint function.
Traditional internal fixation materials may require secondary removal, increasing patient morbidity.

Purpose of the Study:

To evaluate the efficacy and biocompatibility of allogeneic bone nails in treating articular fractures.
To assess the healing process and functional outcomes following fixation with allogeneic bone nails.

Main Methods:

Ninety-one patients with cancellous bone fractures involving joints were treated.
Fixation was achieved using either allogeneic bone nails or bone screws without immunosuppressants.
Average follow-up period was 18 months.

Main Results:

Excellent healing without displacement was observed in 90 out of 91 patients within 1-3 months.
Good joint function was reported in most patients; only 6 experienced partial limitation.
The allogeneic bone nail demonstrated good biological compatibility and mechanical stability.

Conclusions:

Allogeneic bone nails provide rigid fixation for articular fractures due to their biocompatibility and strength.
Complete absorption and ossification of the material obviate the need for secondary surgery.
Allogeneic bone nails are a suitable internal fixation material for articular fracture treatment.
