The patient followed-up at the 2- and 4-month intervals with persistent subluxation. However, the patient also reported minimal pain and the ability to return to work and previous level of activity. Literature Review  Current literature regarding irreducible volar DRUJ dislocations with distal radius fracture dislocations includes sparse case reports, which are reviewed in this report. Clinical Relevance  This case illustrates successful treatment for an uncommon volar DRUJ dislocation associated with a dorsal distal radius fracture dislocation and can be utilized to help guide future treatment of similar complex cases. © Thieme Medical Publishers.Background  Several types of fixation materials may be used for the radial styloid fractures such as Kirschner wire fixation, screw fixation, volar plate fixation, and fragment-specific radial buttress plate fixation. However, each of these fixation techniques has certain complications usually related to either the surgical dissection or the application of fixation and symptomatic permanent hardware. Implant removal secondary to irritation of prominent screw heads or bulky plates is not uncommon after radial styloid fracture fixation. Case Description  Herein, two patients with an isolated radial styloid fracture who were treated with bioabsorbable magnesium (alloy MgYREZr) screws are presented. In both patients, the fracture union was achieved without any complication and need for implant removal. Literature Review  This is the first report on the use of magnesium screws for this indication. Clinical Relevance  Magnesium bioabsorbable compression screw fixation may be an alternative solution that eliminates removal operations due to symptomatic hardware in radial styloid fractures. © Thieme Medical Publishers.Background  Nonunion after open reduction and internal fixation (ORIF) of scaphoid fractures is reported in 5 to 30% of cases; however, predictors of nonunion are not clearly defined. Objective  The purpose of this study is to determine fracture characteristics and surgical factors which may influence progression to nonunion after scaphoid fracture ORIF. Patients and Methods  We performed a retrospective case-control study of scaphoid fractures treated by early ORIF between 2003 and 2017. Inclusion criteria were surgical fixation within 6 months from date of injury and postoperative CT with minimum clinical follow-up of 6 months to evaluate healing. Forty-eight patients were included in this study. Nonunion cases were matched by age, sex, and fracture location to patients who progressed to fracture union in the 12 ratio. Results  This series of 48 patients matched 16 nonunion cases with 32 cases that progressed to union. Fracture location was proximal pole in 15% (7/48) and waist in 85% (41/48). Multivariate regression demonstrated that shorter length of time from injury to initial ORIF and smaller percent of proximal fracture fragment volume were significantly associated with scaphoid nonunion after ORIF (63 vs. 27 days and 34 vs. 40%, respectively). Receiver operating curve analysis revealed that fracture volume below 38% and time from injury to surgery greater than 31 days were associated with nonunion. Conclusion  Increased likelihood for nonunion was found when the fracture was treated greater than 31 days from injury and when fracture volume was less than 38% of the entire scaphoid. Level of Evidence  This is a Level III, therapeutic study. © Thieme Medical Publishers.Background  Closed reduction and cast immobilization of displaced distal radius fractures carries the risk of secondary displacement, which could result in a symptomatic malunion. In patients with a symptomatic malunion, a corrective osteotomy can be performed to improve pain and functional impairment of the wrist joint. Objective  The aim of this study was to assess the functional outcomes of children who underwent a corrective osteotomy due to a symptomatic malunion of the distal radius. Methods  Between 2009 and 2016, all consecutive corrective osteotomies of the distal radius of patients younger than 18 years were reviewed. The primary outcome was functional outcome assessed with the ABILHAND-Kids score. Secondary outcomes were QuickDASH (Quick Disabilities of Arm, Shoulder, and Hand) score, range of motion, complications, and radiological outcomes. Results  A total of 13 patients with a median age of 13 years (interquartile range [IQR] 12.5-16) were included. The median time to follow-up was 31 months (IQR 26-51). The median ABILHAND-Kids score was 42 (range 37-42), and the median QuickDASH was 0 (range 0-39). Range of motion did not differ significantly between the injured and the uninjured sides for all parameters. One patient had a nonunion requiring additional operative treatment. The postoperative radiological parameters showed an improvement of radial inclination, radial height, ulnar variance, dorsal tilt, and dorsal tilt. Conclusion  Corrective osteotomy for children is an effective method for treating symptomatic malunions of the distal radius. Level of Evidence  This is a Level IV study. © Thieme Medical Publishers.Objective  To examine the association between distal radius fractures and tendon entrapment identified on computed tomography (CT) imaging. Patients and Methods  After Institutional Review Board approval, we retrospectively reviewed distal radius fractures that underwent CT imaging from an electronic database between January 2006 to February 2018 at a single level 1 hospital trauma center. We categorized all distal radial fractures according to the AO-OTA (AO Foundation/Orthopaedic Trauma Association) classification. Distal upper extremity tendons were assessed for entrapment. Fisher's exact test was used for statistical analysis with significance at p   less then  0.05. Results  A total of 183 distal radius fractures were identified in 179 patients. P450 (e.g. CYP17) inhibitor A total of 16 fractures (13 males and 3 females) were associated with tendon entrapment. Mechanism of injury included falls ( n  = 7), motor vehicle accidents ( n  = 6), dog bites ( n  = 2), and gunshot wound ( n  = 1). Entrapped tendons were limited to the extensor compartment and included the extensor pollicis longus (EPL; n  = 11), extensor pollicis brevis ( n  = 1), extensor carpi ulnaris ( n  = 1), extensor carpi radialis longus ( n  = 1), and extensor digitorum communis ( n  = 2).
