Summary
Internal fixation plates may cause bone density loss if removed too early. Retaining plates for at least 21 months is recommended to allow bone density to recover fully.
Area of Science:
- Orthopedics
- Bone physiology
Background:
- Internal fixation plates are used to stabilize fractures.
- Plate removal timing can impact bone health.
Purpose of the Study:
- To assess forearm bone density after internal fixation plate removal.
- To determine optimal timing for internal fixation plate removal.
Main Methods:
- Single-photon absorptiometry was used.
- Forearm bone density was measured in 14 patients post-plate removal.
Main Results:
- Cortical atrophy was observed in one patient with premature plate removal (16 months).
- Bone density may not return to prefracture levels by 16 months.
Conclusions:
- Internal fixation plates should remain in place for at least 21 months.
- Prolonged plate retention supports bone density recovery and aligns with AO/ASIF recommendations.
