A Randomized Controlled Clinical Trial to Comparing between Use of Sawdust Plaster Cast Mixture versus Traditional Cast in Accelerating Twisting Healing Duration and Reduced Pain Among Patients

Background and Objectives: Bone fractures pose a serious challenge for the healthcare system worldwide. A total of 17.5% of these fractures occur in the distal radius. Traditional cast materials commonly used for treatment have certain disadvantages, including a lack of mechanical and water resistance, poor hygiene, and odors. This study aimed to compare the efficacy of a sawdust plaster cast mixture versus a traditional cast in accelerating the healing of twisting injuries and reducing pain among patients. Materials and Methods: A randomized clinical trial study was carried out at Al-Kindi Teaching Hospital and Al-Yarmouk Teaching Hospital. The study extended period from May to August 2025. A simple random sample of 60 participants with twisting injuries was selected through a lottery method, with 29 assigned to the intervention group (sawdust-plaster cast mixture) and 31 to the control group (traditional cast). Data were collected using a Visual Analog Scale to measure pain, healing duration, and demographic information. The collected data were analyzed using both descriptive and inferential statistics with the aid of SPSS version 30. Results: The sawdust-plaster cast performed noticeably better than the conventional cast on every metric. Compared to the standard cast (control) group, patients in the sawdust plaster cast mixture (intervention) group reported a noticeably higher reduction in discomfort. The intervention group’s mean pain score was 18.37 ( P < 0.001), compared to 43.47 for the control group. Healing time for the sawdust plaster cast mixture group, the healing period was noticeably shorter. The intervention group’s mean recovery time was 25.11 days ( P = 0.004), compared to 36.26 days for the control group. Conclusions: The study shows that sawdust plaster cast treatment is more effective than standard casts for twisting injuries. The sawdust cast group experienced less pain (18.37 vs. 43.47) and faster recovery (25.11 vs. 36.26 days). These results indicate that sawdust-plaster casts enable quicker healing and better pain management.
