DUL-ITS: Prospective Case Series to Assess Complications of Using Distal Ulna Locking Plate of I.T.S.
Study Details
Study Description
Brief Summary
Background of the study:
Various studies show that the outcome of unstable distal ulna fractures after open reduction and internal fixation is better than closed reduction. The previous plate system for the distal ulna fractures is applied exclusively on the extensor side. This often leads to irritation of the extensor tendons, as well as problems with pronation and supination. With the new shape of the angle-stable distal ulna plate, we hope that the stability of the fracture osteosynthesis will remain the same and that it will be better tolerated with regard to the surrounding soft tissue, especially the extensor tendons. In this way, an otherwise practically unavoidable removal of osteosynthesis material could - at least in some cases - be avoided and some patients spared a follow-up operation.
With this in mind, we try to achieve the greatest possible reconstruction and stability for early functional follow-up treatment with a slightly bulky implant placed in the tendon-free area.

Detailed Description
With this study, the application and usability of the new angle-stable plate system should be determined and documented.
New value of the study:
This system enables an optimal position of the plate on the distal ulna, on the one hand due to the position on the flexor side and on the other hand due to the new shape, adapted to the anatomy of the distal ulna. The locking system using angle-stable screws corresponds to the systems previously used by I.T.S.
Design:
Prospectively, handling, advantages and possible complications of the angle-stable, distal ulna plate; Company I.T.S. in the osteosynthesis of the unstable distal ulna fracture. A total of 20 patients with unstable distal ulna fractures are to be treated and evaluated over a period of 12 months according to the study design.
Risk/Benefit:
With the use of the angle-stable distal ulna plate, company I.T.S. your broken bone may heal better. However, it is also possible that you will not benefit directly from your participation in this clinical trial. The Expected Benefit of the Locking Distal Ulnar Plate;
Company I.T.S. includes:
-
Reduced risk of bone misalignment after surgery.
-
Less risk of irritating tendons on the plate with your new location.
-
A removal of the osteosynthesis material could possibly be avoided.

Outcome Measures
Primary Outcome Measures
- Complicationsrate [1 year]
Percentage of complications rate of patients treated with DUL
Secondary Outcome Measures
- Clinical outcome (range of motion) [1year]
Degree of the possible range of motion using a goniometer to measure the movement angles in correlation of the healing process. The better the range of motion the higher the value. Normally the following limits are given: Radial: least 0 degree, maximum: 20 degree Ulnar: least 0 degree, maximum: 40 degree Extension: least 0 degree, maximum: 70 degree Flexion: least 0 degree, maximum: 70 degree Pronation: least 0 degree, maximum: 90 degree Supination: least 0 degree, maximum: 90 degree
- Clinical outcome (grip strength wrist) [1year]
Extent of possible grip strength measurement using dynanometer in correlation of the healing process. Minimum: 0 kilogram Maximum: 80 kg
- Patient Reported Outcome (function) [1 year]
Percentage of the patients with reduced or normal outcome after fractures using questionnaires like the DASH Score in correlation of the healing process. This is a score reporting the functional outcome, satisfaction and quality of life. Best score is 100%, least score 0%
- Patient Reported Outcome (pain) [1 year]
Percentage of the patients with remaining pain after fracture using the visual analog scale in correlation of the healing process. The scale reports about the intensity of pain. The maximum pain and least score is 10, and the best score is 0 which means "no pain".
