Abstract
Aims of study
To assess and compare the functional, radiological and cosmetic results as well as patient satisfaction in patients treated with the IMN Device Vs Volar Locking Plate
Method
All patients who presented to our institution with extra articular distal radius fractures and met the inclusion criteria were invited to take part in the study. The patients were randomly allocated to two groups, those who underwent intramedullary (IMN) distal radius fixation using the Sanoma Wrx Distal radius nail and those who underwent fixation using a volar locking plate. The patients were then followed up at 2 weeks, 6 weeks, 3 months, 6 months and 1 year. The radiological parameters, ie radial height, inclination and tilt were compared as well as the functional outcomes by means of DASH score. The range of motion of the wrist was compared as well as the scar size. Complications were reviewed.
Results
We present our early results. Currently we have included 9 patients in the IMN group and 7 patients in the volar plate group with follow-ups longer than 3 months. Results show smaller scars (2.5 vs 6.7cm), comparable flexion and extension (40 vs 40 and 45 vs 40), slight improvements in pronation and supination (80 vs 75 and 85 vs 80) in the IMN compared to the volar plate. Radial and ulnar deviation is comparable. The radiological parameters showed slight improvements in the radial height (2.5 vs 2.2 mm), inclination (3.6 vs 3.2 degrees) and tilt 13,7 vs 12 degrees) with the IMN. Dash scores will be compared at 6 months.
Conclusion
Intra medullary nailing of the distal radius seems to compare to volar plating in terms of radiological parameters and rotational stability but has the added benefit of early range of motion, minimal invasive technique, less post op pain and less complications such as tendon irritation.
