Abstract

BACKGROUND:

In Japan we currently use absorption properties for facial fractures. OSTEOTRANS MX(®) (Takiron co., ltd, Japan) is an absorption device, which is called Super FIXSORB MX(®) in Japan. This absorbable osteosynthetic device constitutes unsintered hydroxyapatite particles/poly l-lactide (u-HA/PLLA) composites. This study focuses on reporting clinical cases of using OSTEOTRANS MX(®).

MATERIALS AND METHODS:

Seventeen patients (16 men and 1 woman) aged 10-80 years (mean: 39.9 years, SD: ±20.7) with 86 fracture sites were treated. In all cases we used 1.0 mm plates and 5 mm or 7 mm screws. The postoperative observation period was 6-60 months (mean: 21.8 months, SD: ±14.5).

RESULTS:

The fracture site recovered in all cases. Complications included one bone excess on the forehead and one foreign-body reaction on the frontozygomatic suture, but the fracture sites were recovered and had no problems. In the case with the longest observation time 60 months, the plate was almost fully absorbed. However, in other cases the plate was not fully absorbed because of a shorter observation time.

CONCLUSION:

OSTEOTRANS MX(®) is a useful device because of its suitable intensity, thinness, radiopaque, and few complications. A longer observation time is required for a plate to be absorbed completely.
