The patient was diagnosed with a Bado type I Monteggia fracture. The fracture was reduced using closed reduction under fluoroscopy followed by Kirschner’s wire fixation. This case is unique because the FDP was found entrapped in the fracture site 2 weeks post-operation and was managed using conservative therapy. FDP entrapment is typically managed by surgical intervention, and there have been no previous reports of conservative management. The FDP was released using passive extension of the index finger under general anesthesia, and no irreversible damage to the tendon or muscle was found. This case report demonstrates the potential for conservative therapy in the management of FDP entrapment after forearm fractures.Keywords: pediatric fracture, entrapment of FDP, conservative therapy, dynamic tenodesis effect, forearm fracture, rehabilitation
