Summary
Serial bone scans using 99-M-Tc-MDP in Colles' fractures reveal a healing pattern. High activity ratios late in healing correlate with fracture redisplacement, aiding in monitoring recovery.
Area of Science:
- Orthopedics
- Nuclear Medicine
- Radiology
Background:
- Colles' fractures are common wrist injuries.
- Assessing fracture healing and displacement is clinically important.
Purpose of the Study:
- To evaluate the utility of serial bone scintigraphy in monitoring Colles' fracture healing.
- To establish a method for quantifying healing activity using 99-M-Tc-MDP bone scans.
Main Methods:
- 15 patients with extra-articular dorsal-angulated distal radius fractures (Colles' fractures) underwent serial bone scintigraphy.
- Technetium-99m methylene diphosphonate (99-M-Tc-MDP) was used for scanning.
- A method for quantifying healing activity via activity-ratios was developed and applied.
Main Results:
- The activity-ratios demonstrated a characteristic pattern indicative of the healing progression over time.
- A significant correlation was observed between high activity ratios detected late in the healing period and subsequent fracture redisplacement.
Conclusions:
- Serial 99-M-Tc-MDP bone scintigraphy can effectively quantify healing activity in Colles' fractures.
- Elevated late-stage activity ratios may predict the risk of fracture redisplacement, informing clinical management.
