Abstract PDF: Background
In severe comminuted metaphyseal distal radius fracture (DRF) of elderly patients, after maintaining only radiological parameters of the radius using long volar locking plates (VLPs), we inevitably eliminated a few volar cortical fragments of metaphysis. Here, we report the final radiological and clinical outcomes of our method. Methods: For the patients who were treated between 2014 and 2018, the demographic factors, the preoperative radiologic factors, area of the eliminated volar cortical fragment, and final radiologic parameter, were evaluated. Clinical outcomes and ranges of active motion were evaluated. Results: In total, 31 patients were included. The mean patient age was 77.3 years and the mean eliminated cortical area was 3.30 cm2. At the final follow-up, the mean volar tilt, radial inclination, articular step-off, and ulnar variance were 10.35°, 20.00°, 0.58 mm, and 0.71 mm, respectively. There were no definitive correlations between bone mineral density, fragment area, the largest cortical fragment diameter ratio and differences in final and immediate postoperative measurements of these radiological parameters, respectively. Visual analog scale and disabilities of the arm, shoulder, and hand (DASH) scores were satisfactory, and the mean arcs of flexion-extension and pronation-supination were 124.35° and 133.23°. Clinical outcomes were not significantly different according to the AO system category. Conclusions: For maintenance of radiological parameters of the radius, long VLPs are useful in older patients with DRFs who exhibit volar metaphyseal comminution, despite concurrent ulnar fractures. Inevitable elimination of irreducible free comminuted cortical fragments when filling the defect does not affect final radiological and clinical outcomes. Level of evidence: Level IV, case series.

Malunion: Deformity Correction of the Upper Extremity: Soo Min Cha, Hyun Dae Shin; J Korean Fract Soc 2017;30(4):209-218. Published online October 31, 2017; DOI: https://doi.org/10.12671/jkfs.2017.30.4.209

Abstract PDF: Malunions after fractures are classified as shortened, angulated, torsion, or rotational deformities that is outside the acceptable range, regardless of the location, whether upper or lower extremity. The distinct feature of a malunion in the upper extremity is that it is free from weight bearing; thus, some degree of shortening is allowed compared with the contralateral normal side in long bones, such as the humerus, radius, or ulna. However, malunions associated with functional impairment, especially angulated or rotational deformities, are more likely to develop instability, degenerative lesions, or rarely, compressive neuropathy. Hence, malunions with such association may occasionally require correction.
