Abstract
DRFs have been discussed in the literature for over two hundred years. They represent one sixth of fractures presenting to the Emergency department.
The volar rim fragment, also known as The Critical Fragment, has gained considerable attention lately because it’s importance for wrist stability and preventing volar carpal sublaxation.
The aim of the work was to evaluate the results of spring wire technique for stabilization of volar rim fragment in complex DRFs.
The mean age of the patients was 38.80 ± 9.2. There was no statistically significant relationship between age and final score (P=0.574). In regards to gender in this study, there were sixteen males (80%), and four females (20%). There was no statistically significant relationship between gender and final score (P=0.468).
Patients presenting with volar carpal sublaxation preoperative were eight patients (40%) which emphasis the need for stable fixation of this critical fragment to avoid later volar carpal sublaxation.
At the end of the six months follow up period patients were assessed using El-Hadara wrist function scoring system out of 24 points, and patient related wrist evaluation tool (PRWE) on a scale of 0-100. Results showed that seven patients (35%) had excellent results (scores between 21 and 23), ten patients (50%) had good results (scores between 17 and 19) and three patients (15%) had fair results (scores between 14 and 16). No patients were graded as poor results. Results showed that the mean score was 18.85±2.66. Regarding PRWE score results showed that the least score was 1 and the highest score was 44, and the mean score was 13.25±12.30. Age, gender, occupation, mode of trauma, dominant hand affection, time laps before surgery and associated ulnar styloid fracture had not shown any statistical significance between them and final outcome scoring (P value >0.05).
Radiological parameters were assessed and correlated to the final outcome, including radial height, volar tilt, radial inclination, ulnar variance and ulnar corner subsidence. There was no statistical significant relationship between all of them and final score.
There were no complications occurred during follow up. All patients had stable united volar rim fragment with no volar carpal sublaxation at the end of follow up period
