Summary
Bone grafting effectively treats metacarpal non-unions, leading to successful bone fusion and pain relief. This method ensures good hand function recovery with minimal complications.
Area of Science:
- Orthopedic Surgery
- Regenerative Medicine
Background:
- Metacarpal non-unions cause significant hand impairment.
- Bone grafting is a key treatment for these complex defects.
Purpose of the Study:
- To review bone grafting outcomes for metacarpal non-unions.
- To inform optimal therapeutic protocols for this complication.
Main Methods:
- Systematic review following PRISMA guidelines.
- Duplicate data collection and analysis.
- Focus on radiological union time and non-union rates, plus functional outcomes and complications.
Main Results:
- 18 studies, 47 patients; average follow-up 12.4 months.
- Average bone fusion time 6.9 months with 100% union rate in 42 patients.
- 76% pain relief, 100% return to baseline hand function; 11.8% complication rate (hematoma/seroma).
Conclusions:
- Bone grafting (vascularized and non-vascularized) is successful for metacarpal non-union.
- Favorable union rates, pain reduction, functional recovery, and minimal complications observed.
- Bone grafts offer an effective management strategy for metacarpal non-unions.
