Introduction- Monteggia is a fracture of the proximal third of the ulna with dislocation of the radial head from both the proximal radioulnar and radio-capitellar joints. At present in most case scenario all the monteggia fractures in adults operated with ORIF platting but hereby we have study about monteggia fracture managed with CRIF with rush nail compared with ORIF and platting. This study aimed to see the clinical and functional outcome of m Aim- onteggia fracture xation with Rush nail compared to platting in adult. A prospective study was conducted over 6 months of a total of 30 patients Material and Method- with monteggia fracture operated with rush nail and 30 patient operated with platting. Patients were divided by randomized controlled trial. All these 60 patients were followed up for mean duration of 6 months. The postoperative Mayo Elbow Performance Index at the tim Results- e of follow-up ranged from 65 to 100, with twenty-two excellent, ve good, three fair, and no poor results in operated case with rush nail and twenty-three excellent, four good, three fair, no poor result in operated case with platting. The radial head remained in a completely reduced position in twenty-ve patient (86%) and was subluxated in ve patients (14%) in operated case with rush nail and radial head completely reduced position in twenty-eight patient (94%) and was subluxated in two patient (6%) in operated case with platting at the time of the latest follow-up. Radiographically, there were twenty-six good, four fair, and no poor results operated with rush nail. A good radiographic result was obtained in all of the patients who had undergone open reduction and platting within three years after the injury. In overall comparison of Conclusion- clinical, functional and radiological outcome it was found that Rush nail gives superior results than platting.

Background: Forearm shaft fractures are common in developing countries. Anatomical reduction of these fractures using plates and screws is considered an accepted treatment mode. Like other shaft fractures, this can be treated with intramedullary nails like square nails, Rush nails, and interlocking nails. This study evaluates radiological and functional treatment results using square nailing. Methods: A prospective study was conducted on 100 adult patients with diaphyseal forearm fractures over 3 years. Out of 100 patients, 68 were men, and 32 were women. Patients were followed up at 2 weeks, 6 weeks, 8 weeks, and then every 3 months till 1 to 1.5 years. We have used criteria described by Anderson et al. and the shortened version of the Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score for functional evaluation of the patients. Results: Out of 100 patients, the union was achieved in 88 patients, while the rest 12 patients required re-surgery. 4 patients had delayed union, 4 patients developed an infection at the ulnar entry site, and 3 patients developed bursitis of olecranon bursa. Conclusion: Intramedullary nailing of both bone forearm shaft fractures using square nails can give satisfactory results in most cases, comparable with treatment by plates and screws, and provides an alternative, cost-effective treatment of both bone forearm shafts fractures with good cosmesis owing to small incisions.
