Little information exists about three-dimensional (3-D) deformity patterns of malunited distal radius fractures including axial deformity. The current study aimed to clarify the 3-D deformity pattern of malunited distal radius fractures and reveal the influence of osseous deformities, including axial rotation deformity, on wrist and forearm motion. The deformity of 20 dorsally tilted malunions were evaluated using 3-D computer models created from CT data, and correlations between deformity components and range of motion were assessed. The 3-D deformity analysis showed that axial malalignment in pronation, which showed a correlation with the degree of radial tilt deformity, was very common. A radial tilt deformity of > 5° was observed in only 45% of cases. Although the range of wrist flexion and extension showed a correlation with dorsal tilt deformity, the range of forearm pronation and supination did not correlate with distal radius deformities.

Volar Plate Fixation

Background No consensus exists regarding postoperative splinting position following volar plate fixation of distal radius fractures. Purpose The purpose of this study was to determine whether immobilization in supination would result in superior outcomes compared with no restriction of forearm range of motion. Patients and Methods All patients >18 years of age with distal radius fractures indicated for volar plate fixation were eligible. Exclusion criteria were open fracture and concomitant injury to, or functional deficit of, either upper extremity. Patients were randomized to immobilization in (1) maximal supination with a sugar-tong splint or (2) no restriction of supination with a volar splint. Patient-Rated Wrist Evaluation (PRWE), Disabilities of the Arm, Shoulder, and Hand (DASH) score, and visual analog scale (VAS) score; wrist range of motion; and grip strength were recorded at 2 and 6 weeks postoperatively. A Student's t-test was used to compare mean values of all outcome measures at each time point. Results A total of 46 patients enrolled in the study; 28 were immobilized with a volar splint and 18 were immobilized with a sugar-tong splint. Six-week follow-up data were obtained for 32 patients. There was no significant difference in PRWE, DASH, and VAS scores; or range of motion; or grip strength between the two groups postoperatively. Conclusion Range of motion, grip strength, and patient-rated outcome measures were similar regardless of postoperative immobilization technique in patients with a distal radius fractures stabilized with a volar plate. Surgeons can elect to use the standard-of-care postoperative immobilization modality of their preference following volar plate fixation without compromising short-term return to function. Level of Evidence This is a Level II, therapeutic study.

The Mean

Background Intra-articular distal radius fractures with small volar lunate facet fragments can be challenging to address with volar plate fixation alone. Volar locked plating with supplementary spring wire fixation has been previously described in a small series but has not been further described in the literature. We hypothesized that this technique can provide adequate fixation for volar lunate facet fragments smaller than 15 mm in length, which are at risk of displacement. Methods We completed a retrospective chart review (2015-2019) of patients who underwent volar locked plating with the addition of supplementary spring wire fixation for intra-articular distal radius fractures with a volar lunate facet fragment (<15 mm). Postoperative radiographs were assessed to evaluate union, evidence of hardware failure, escape of the volar lunate facet fragment, and postoperative volar tilt. Clinical outcome was assessed with wrist flexion/extension, arc of pronosupination, and Quick Disabilities of the Arm, Shoulder, and Hand Score ( QuickDASH) scores. Results Fifteen patients were identified, of which all went on to fracture union. There were no hardware failures or escape of the volar lunate facet fragment at final follow-up. One patient underwent hardware removal for symptoms of flexor tendon irritation. The mean wrist flexion was 59°, wrist extension was 70°, pronation was 81°, and supination was 76°. The mean QuickDASH score was 18.5. The mean postoperative volar tilt was 3.6°. Conclusions Supplementary spring wire fixation with standard volar plating provides stable fixation for lunate facet fragments less than 15 mm. This technique is a safe and reliable alternative to commercially available fragment-specific implants.

Background: The treatment strategy for distal radius fractures accompanied by volar lunate facet fragment is controversial. In most cases, only the bone fragment size was discussed and a plate for distal placement is selected due to the accompanying volar lunate facet fragment regardless of the direction of bone fragment displacement. In this study, we divided distal radius fractures accompanied by volar lunate facet fragment into dorsal and volar displaced fractures, and treated these surgically based on different treatment strategies. Methods: The subjects were 25 patients with distal radius fractures accompanied by volar lunate facet fragment treated by reduction and fixation using a volar locking plate (VLP) (male: 14, female: 11, mean age: 57.8 years old). A proximal VLP (PVLP) was selected for 13 dorsal displaced fractures and a distal VLP (DVLP) was selected for 12 volar displaced fractures. The range of motion, VAS, Q-DASH, and Mayo score were evaluated at 12 months after surgery, and compared. Results: No significant difference due to the difference in the direction of displacement was noted in the range of motion, VAS, Q-DASH, or Mayo score at 12 months after surgery and there were no perioperative complications. In addition, no re-displacement of volar lunate facet fragment was noted after surgery in any patient and bone fusion was observed. Conclusions: Reduction and fixation with a PVLP are possible even for dorsal displaced distal radius fractures accompanied by volar lunate facet fragment. For the volar displaced distal radius fractures, a favorable postoperative outcome is possible by applying a DVLP to the distal ulnar.

Three Dimensional Models

The purpose of this study was to develop plates that fit the contour of the distal radius of the Japanese and can be inserted less invasively. Three-dimensional models of 36 radii of 18 volunteers were prepared. Using these models, the shape of the cortical bone on the radial margin of the distal radius and just below the dorsal fourth compartment of the wrist, to which the plates were expected to be applied, was measured, and the curves of the plates were determined. The functions of approximated curves of the plates were: [ y = -2 × 10-8 x 5 - 2 × 10-6 x 4 + 0.0006 x 3 - 0.0312 x 2 + 0.3274 x + 15.224 on the radial margin of the distal radius and [ y = 7 × 10-7 x 5 - 0.0001 x 4 + 0.0078 x 3 - 0.2355 x 2 + 3.1815 x - 5.6383 just below the fourth compartment. The clinical results of the application of double dorsal plates were satisfactory in clinical cases for the distal radius fractures.

The objective of this study was to compare the clinical results of unstable distal radius fractures treated with ORIF with plate and screws compared to EF. Patients with unstable distal radius fractures treated with ORIF or EF from January 2005 to December 2010 were reviewed in terms of the Modified Mayo Wrist Score, range of motion, pain, grip strength, and radiologic parameters. Results showed that there was no difference in the Modified Mayo Wrist Score between ORIF (17 patients) and EF (11 patients) (p = 0.07). The ORIF group had better wrist flexion, wrist extension, pronation and supination compared to the EF group (p < 0.05). There were no significant differences in terms of radial and ulnar deviation, grip strength, pain and postoperative radiologic parameters (p < 0.05). Better wrist flexion, wrist extension and forearm rotation can be expected in ORIF compared to EF in the management of unstable distal radius fractures.

Background: This study aimed to identify the effect of the progression of postoperative wrist osteoarthritis on 5 years clinical and radiological outcomes after volar locking plate fixation of distal radius fractures. Methods: Altogether, 56 patients with distal radius fractures were followed up 5 years after surgery. Clinical assessment was performed using the Mayo modified wrist score, a visual analogue scale of pain, the Japanese version of the Disabilities of the Arm, Shoulder, and Hand score, and Patient-related wrist evaluation. Standardized wrist radiographs were used to assess wrist morphology and the Knirk and Jupiter’s degree of osteoarthritis. Multivariate logistic regression was used to analyze postoperative morphological changes in the wrist and carpal alignment regarding their correlation with progression of wrist osteoarthritis. Results: Progression of postoperative wrist osteoarthritis was recognized in 37 of the 56 cases (66.1%). Compared with the clinical outcomes at the time of the fracture union completion, almost clinical outcomes improved up to 5 years follow-up time as well as at 1 year after surgery. The range of wrist flexion at 5 years follow-up was significantly less in the progressive osteoarthritis group than in those with non-progressive osteoarthritis. The persistent step-off immediately after surgery significantly affected the postoperative progression of wrist osteoarthritis. Changes in the radial inclination, volar tilt, and radioscaphoid angle correlated with progression of wrist osteoarthritis. The highest correlation was with the change of radioscaphoid angle. Conclusions: Good clinical results were maintained at 5 years after surgery, but progression of postoperative wrist osteoarthritis interfered with improvement of wrist flexion. Change in the radioscaphoid angle was the factor that was most highly correlated with progression of postoperative wrist osteoarthritis.
