This case report details the rehabilitation procedure for a 35-year-old man involved in a vehicle accident that resulted in multiple joint fractures. The patient had fractures to the proximal tibia, left bimalleolar, posterior malleolus, fourth and fifth metacarpal heads, and second and third proximal phalanges. After open reduction and internal fixation surgery, an 8-12 week physical treatment regimen was put into place. Exercises for both passive and active range of motion, isometric and progressive resistance training, and gait training were provided. The rehabilitation goals were pain relief, increased range of motion, muscle strength, flexibility, endurance, and functional independence. Pain levels, range of motion, muscle strength, and general function all significantly improved between pre- and post-rehabilitation evaluations. Early mobilization and structured physical therapy were crucial in achieving these outcomes, highlighting the importance of tailored rehabilitation protocols for post-operative recovery.
