    Background Although distal radius fractures (DRF) are common fractures, intra-articular comminuted DRF with volar free fragments are uncommon. There is considerable difficulty in the fixation of free fragments beyond the watershed line using the existing volar locking plate. We aimed to examine the efficacy and potential complications associated with the use of juxta-articular volar plates in intra-articular DRF accompanied by free fragments beyond the watershed line. Methods The patients were enrolled in a consecutive manner between 2007 and 2016. In cases of DRF with free fragments beyond the watershed line, we employed a 2.4-mm small fragment juxta-articular volar locking compression plate using a volar Henry approach. A total of 32 patients were included in this study. There were 15 males and 17 females with a mean age of 52.3 years (range, 33 to 69 years). The mean follow-up period was 14.5 months (range, 10 to 24 months). Preoperative radiographs and three-dimensional computed tomography images were used to analyze fracture patterns and assess the free fragments beyond the watershed line. The mean number of free fracture fragments beyond the watershed line was 2.33. Plain radiographs of immediate postoperative and last follow-up were used to confirm fracture union, incongruence, radial height, volar tilt, radial inclination, and arthritic changes. For functional assessment, we measured grip strength, range of motion (ROM), modified Mayo wrist score (MMWS) and determined Disabilities of Arm, Shoulder and Hand (DASH) scores at the last follow-up. Postoperative complications were monitored during the follow-up period. Results All patients obtained sound union without significant complications. At the last follow-up, 16 cases presented with an articular step-off of more than 1 mm (mean, 1.10 mm). The mean MMWS was 76.3 (range, 55 to 90), mean DASH score was 15.38 (range, 9 to 22), mean visual analogue scale score for pain was 1.2 and mean grip strength was 75.5% of the opposite side. The mean ROM was 74.3° for volar flexion and 71.5° for dorsiflexion. Conclusions In cases of intra-articular DRF with free fragments beyond the watershed line, a volar approach with use of a juxtaarticular plate provided favorable outcomes without significant complications.
