Distal radius fractures are very common injuries presenting with a bimodal distribution. Road traffic accident (RTA) is the most common cause in young patients, whereas a simple fall occurs in the geriatric population. The high amount of cancellous bone and low cortical bone in the metaphyseal region of the distal radius is a predisposing factor for fracture. Distal radioulnar joint (DRUJ) injury may be associated with distal radius fractures, which are often missed and not treated, leading to disability. DRUJ restoration is essential for normal wrist and forearm movements. DRUJ injuries should be promptly identified and treated. This study is intended to identify the incidence of DRUJ injury and compare conservative management with K-wire fixation of DRUJ injuries with instability. Distal radius fracture was treated with a standard volar plating technique. The intraoperative instability of DRUJ was tested using the ballottement test. Alternate patients were treated with the conservative method and surgical K-wire fixation of DRUJ injury. A plaster of Paris slab was applied above the elbow as conservative management for 3 weeks. Later, physiotherapy was advised. K-wire fixation was done for DRUJ in surgically treated patients, and K-wire was removed after 3 weeks. Patients were followed at regular intervals, both radiologically and clinically. Garland and Werley's scoring system was used to evaluate wrist functional outcomes. Our study concludes that there is no significant difference in functional outcome between conservative and surgical treatment of DRUJ injury in distal radius fractures.
