The document presents a study protocol to evaluate outcomes of radius and ulna shaft fractures in adults treated with titanium elastic nailing. The study will assess range of motion, time to bone union, complications, and functional outcomes in 50 patients over 18-60 years old with displaced double forearm fractures treated with intramedullary nailing. A review of previous literature found that intramedullary nailing provides advantages like closed application and early return to movement for forearm fractures.
