Non-invasiveness, avoidance of complications and comfort are important issues in the clinical management of conservatively treated distal radius and scaphoid fractures. To date, applying a plaster cast for approximately 6 weeks of immobilization is the gold standard. However, new 3D-technologies such as the design of Patient Specific Anatomical Braces (PSAB) will lead to a new paradigm of treatment. Swibrace has developed such anatomical, light, elegant and yet resistant braces. First, the fractured limb is scanned, the data then sent to a specifically designed software, printed in a 3D-printer and finally sent to the hospital for the patient's fitting. As these PSAB have not yet been tested on patients, the primary purpose of this study is to evaluate whether patient satisfaction with a 3D-printed PSAB differs from the one of traditionally treated patients in a plaster cast. (A pre-clinical study will be conducted with 10 healthy volunteers testing the 3D splint for 72h. Only if splint satisfaction will be ≥ 70% as measured by the self-designed "Adult Rated Splint Evaluation Questionnaire" (ARSEQ), the 3D splint will be tested in patients. Otherwise, adjustments to the splint will be made based on the healthy volunteers' feedback prior to its testing in patients.)

Primary | Change in "Patient Reported Splint Evaluation Questionnaire (PRSEQ)" | The investigators designed this questionnaire to the best of their knowledge due to lack of pre-existing orthosis satisfaction questionnaires suitable for the study purposes. The PRSEQ will be completed by the participating patients. It consists of two parts:
Part 1 consist of 5 main topics: (1) pain because of the splint, (2) personal experiences with the splint, (3) personal safety, (4) specific and (5) usual activities in the splint. Pictures from the splint are given to allow ticking pressure marks and skin irritations where they appeared. Part 2 consists of 3 main topics: (6) satisfaction with the splint, (7) personal attitude and (8) satisfaction with the scanning procedure. Each main topic includes several sub-questions, where the patient rates his/her answers on a 11-point-Likert scale (0-10). |
Part 1 will be filled out during (at week 2, 4, 6) and Part 2 after the splint wearing time (week 6). | |
Secondary | Hand therapy evaluation - applying the "assessment of patient satisfaction" | The assessment of patient satisfaction consists of 4 domains (patient comfort, patient compliance, cast odor and smell, skin itchiness) being rated on a 0-3 Likert Scale (0 = poor, 3 = excellent) by specialized hand therapists. | Assessed during 6 hand therapy visits on a weekly basis until week 6, starting in week 1 | |
Secondary | Hand therapy evaluation - finger range of motion as assessed by a hand-held goniometer | The hand-held goniometer will be used to measure the distances between the finger tips and the palm of the hand in centimeters. A touch-down (finger tips touch the palm) will be judged with "yes/no". Both finger range of motion measurements will be assessed by specialized hand therapists. | Assessed during 6 hand therapy visits on a weekly basis until week 6, starting in week 1 | |
Secondary | Hand therapy evaluation - sensibility as measured by the "Ten Test" | Specialized hand therapists will assess sensibility by applying the quantitative sensory test "Ten Test". The patient reports his/her light touch perception of the skin area being tested compared to the reference normal area when the examiner (hand therapist) gives a simultaneous stimulus by stroking a normal area and the area under examination. The response from the patient rating the sensibility of the test area is recorded as a fraction out of 10 between 1/10 and 10/10 (10 = normal sensory perception). | Assessed during 6 hand therapy visits on a weekly basis until week 6, starting in week 1 | |
Secondary | Hand therapy evaluation - pain as measured by the "Numeric Rating Scale" | Specialized hand therapists will assess pain using the Numeric Rating Scale for pain. It requires the patient to rate their pain on a defined scale from 0-10, where 0 is no pain and 10 is the worst pain imaginable. Patients are asked to circle their current pain in their hand on this scale. | Assessed during 6 hand therapy visits on a weekly basis until week 6, starting in week 1 | |
Secondary | Bone position - x-ray evaluation by specialized hand surgeons and orthopedists | Bone healing process is closely monitored by specialized hand surgeons and orthopedists by taking an x-ray on several time points:
- one week after the accident to check if the bone is not displaced to guarantee that a conservative treatment may be continued. in case of any uncertainties, another x-ray will take place during week 2 after the accident to check on the bone's position again. - after 6 weeks, the last x-ray will be made to decide removal of the plaster cast / 3D splint |
2-3 regular x-rays will take place during the bone healing phase after 1 week of splint wearing, if necessary in week 2 and after 6 weeks as assessed by physicians | |
Secondary | Questionnaire "assessment of clinical effectiveness" as rated by specialized hand surgeons and orthopedists | The "assessment of clinical effectiveness" is an assessment where 4 domains are judged by specialized hand surgeons or orthopedists on a 0-3 Likert Scale (0 = poor, 3 = excellent). These are: stability of immobilization, blood circulation, wear pressure-related pain and pressure sores. | Administered once at the end of the study after 6 weeks | |
Secondary | Composite endpoint "adherence" assessed as the "number of clinical visits that were missed" / "number of drop-outs" and "number of patients crossing over to the plaster cast group" | Adherence will be documented by clinicians (hand therapists and physicians) in terms of counts of: clinical visits that have taken place (or being missed), drop-out or cross-over rates to the plaster cast group. | Ongoing during the whole study period of 6 weeks |
