Upper Extremity Fractures

The purpose of this clinical trial is to learn whether the use of a "cold and arm sling elevation pillow" affects anxiety and comfort levels in children aged 7-12 years undergoing surgery for upper extremity fractures. The main questions it aims to answer are: * Does the use of a cold and arm sling elevation pillow reduce postoperative anxiety levels in children? * Does the use of a cold and arm sling elevation pillow increase postoperative comfort levels in children? Researchers will compare the experimental group (using the specially designed cold and arm sling elevation pillow) with the control group (receiving standard clinical care, including standard pillows and separate ice packs) to see the effects of the integrated pillow on anxiety and comfort. Participants will: * Receive education before surgery based on their randomly assigned group (experimental or control), * Use the assigned elevation and cold application method for the first 24 hours following surgery, * Complete anxiety and comfort assessment scales at four different time points: before the intervention, just before surgery, 6 hours after surgery, and at the time of discharge.

This prospective, two-arm, open-label clinical trial compares digital aftercare with traditional follow-up in adult patients after surgical treatment of uncomplicated distal radius or clavicle fractures. The primary objective is to assess functional recovery at three months, using the Patient-Rated Wrist Evaluation (PRWE) for wrist fractures and the QuickDASH for clavicle fractures. Secondary outcomes include range of motion, patient satisfaction, quality of life, complication rates, healthcare costs, and work disability. In the digital aftercare group, program adherence and user experience will also be evaluated through app usage data and a structured questionnaire. The study aims to determine whether digital aftercare is a clinically and economically equivalent alternative to standard in-person care.
