Abstract
Introduction: To compare the results of external fixator augmented with bone marrow injection in the management of distal radial fractures with that of fixator alone in preventing late metaphyseal collapse
Materials and Methods: Patients with severely comminuted metaphyseal fracture of the distal radius were only included in the study. The fractures were of Frykman-VII or Frykman-VIII types and reducible unstable type as per universal classification.
Results: 93.3% of cases in Group-II, showed good to excellent anatomical results after one year and only 56.7% in Group-1 (p<0.005). Functional results were good to excellent in 90% in Group-II and it was 56.7% in Group-I (p<0.02). This shows that Group-II patients who were treated by bone marrow injection along with ligamentotaxis obtained better results and it is statistically significant also. Comparison of the anatomical results to functional result showed that good anatomical result was a prerequisite for good functional result.
Conclusion: External fixators based on the principle of ligamentotaxis gives better anatomical and functional results initially, but on follow-up results deteriorate due to late metaphyseal collapse, which can be effectively prevented by injection of bone marrow into the metaphyseal defect.
