U.S. Army Spc. Jaylen Bussey, a Medical Education and Training Campus Occupational Therapy Assistant course student assigned to the 264th Medical Battalion, molds a custom splint to another student’s wrist and hand at Joint Base San Antonio-Fort Sam Houston on June 16, 2026.

These custom splints support tissue healing and joint rehabilitation.
