To begin with, a strong distal radius anatomical reconstruction is essential for a successful result, particularly in the case of an active patient. For distal radius fractures, recent studies have shown that surgical therapy is preferable to closed reduction and cast treatment, based on wrist biomechanics and complicated fracture instability. External fixation vs open reduction and plate fixation in distal radius fractures were compared in this thesis for functional and radiological results. The purpose of this research was to compare the surgical therapy of unstable distal radius fractures utilising external fixation versus internal fixation. At Benha University Hospitals and El-elahrar Educational Hospital, there were 30 adult patients with solitary distal radius fractures, separated into two groups. Results: Radiographs of the patients were used to gather the anatomical information. flexion, extension, ulnar deviation, radial deviation, and supination and pronation) at the 12-month mark were documented. In addition, grip strength and Quick DASH scores were measured at 3, 6, and 12 months. These two management tiers' radiological and functional results were compared. Surgical therapy of distal radius fractures with internal and external fixation was successful in our research, with satisfactory functional outcomes. Age, gender, fracture side, and mechanism of injury were not shown to affect fracture outcome in our research. The plate group had improved flexion, extension, supination and pronation, radial length, and palmar tilt in our research. Also, this group had lower Quick DASH scores and fewer problems. For distal radius fractures, both ORIF with a plate and external fixation are excellent options. More stable fixation, early wrist range of motion, and lower Quick DASH scores were seen in the open reduction and plate fixation group than in the external fixator group, which also permitted superior anatomical alignment and improved radiological results. In early follow-up visits, the plate group had better grip strength than the external fixator group. Complications were reported by a higher percentage of patients in the external fixator group than in the plating group. Plaque fixing was thus linked to improved results on both the functional and radiographic side
