The volar rim fragments play a critical role in radiocarpal joint stability and failing to secure the volar rim fragment usually results in carpal instability, subluxation, or even dislocation. This study investigates clinical outcomes in the use of a novel implant, the Trident distal radial (TDR) locking plate to treat distal radius fracture with the intermedium column edge (lunate fossa volar rim) fragment involvement. Methods: A retrospective study of 25 patients was conducted, all patients had intermedium column fractures with lunate fossa volar rim involvement and treat with the TDR between January 2016 and December 2019. The clinical assessment outcomes included VAS Pain, PRWE, and DASH scores. Objective measurements included ROM of the injured wrist and grip strength. Final radiographs were used to evaluate radial inclination, volar tilt, ulnar variance, and distal radioulnar joint instability. Secondary operations related to hardware complications were also recorded.  \nResults: The outcome revealed that the mean VAS Pain Score was 1.3, mean DASH score was 10.5, and mean PRWE score was 9.3. Objective measurements revealed good ROM recovery and an 89% gripping strength recovery compared with contralateral hand. Radiographic measurements revealed good maintenance of volar tilt, radial inclination, and mean ulnar variance. There were no complications related to the implant and all fracture sites were union.  \nConclusion: We believe that the TDR provided more stable fixation among distal radial fractures that predominantly involved the intermedial column and volar rim fragment, and allowing early rehabilitation. We could obtain excellent results in the wrist ROM, gripping power, and Pain Score (VAS) .  \nKeywords: Distal radius fracture; Fragment-specific fixation; Intermedium column; Trident distal radial (TDR) locking plate; Volar rim  \n1. INTRODUCTION  \nThe distal radial fracture is one of the most common fractures of the upper extremity and accounts for 10% to 20% of all fractures in adults.1 The volar locking plate (VLP), introduced in the year 2000 and now widely used, has significantly changed the treatment protocol for unstable distal radius fractures.2 Even though the VLP has generally excellent posttreatment outcomes, it still has several limitations when dealing with small fragments located around the watershed line.3–6 In this fracture pattern, complications have been widely reported, which include implant loss of reduction, carpal instability and subluxation, irritation of flexor and extensor tendons, and implant removal associated with intra-articular screw trajectory and hardware prominence.4–8  \n* Address correspondence.
