Ulnar styloid fractures associated with distal radius fractures: incidence and implications for distal radioulnar joint instability

Ulnar-sided injuries of the wrist have received more attention recently for their potential negative impact on the outcome of distal radius fractures. Radiographs and medical records were retrospectively reviewed for 166 distal radius fractures treated during a 1-year interval. Distal radius fractures were classified according to the AO system, and accompanying ulnar styloid fractures were evaluated for both size and displacement. Each distal radius fracture was also evaluated for radiographic and clinical evidence of distal radioulnar joint instability. The distribution of ulnar styloid fractures was not random; greater than one third involved the base. All distal radius fractures complicated by distal radioulnar joint instability were accompanied by an ulnar styloid fracture. A fracture at the ulnar styloid's base and significant displacement of an ulnar styloid fracture were found to increase the risk of distal radioulnar joint instability.     

Intraoperative evaluation of DRUJ instability through dorsal stress radiography in distal radius fractures

IntroductionCertain type of injury of the triangular fibrocartilage complex associated with distal radius fracture can result in distal radioulnar joint instability (DRUJ). Untreated DRUJ instability may lead to poor result in the treatment of acute distal radius fractures. The aim of this study was to evaluate DRUJ instability in distal radius fractures through dorsal stress radiography comparing the affected and unaffected wrists intraoperatively.Materials and methods49 patients with a distal radius fracture who were operatively treated with a volar locking plate were included. Dorsal stress radiography was used to evaluate both affected and unaffected wrists peri-operatively to detect DRUJ instability. Under general anesthesia, a dorsal stress test was performed on the unaffected wrist. Additionally, after fixation of the affected wrist, a dorsal stress test was performed. The ulnar translation ratio (UTR) was measured through the dorsal stress radiograph. Arthroscopic examination was performed on all affected wrists according to Palmer's and Atzei classification.ResultsThe UTR of the affected wrist and the TFCC injury Palmer-type IB tendency were positively correlated (odds ratio: 1.18, p-value: 0.002). Additionally, as the UTR difference between the affected and unaffected wrists enlarged, it revealed a significant DRUJ instability tendency due to Palmer-type IB TFCC injury (p-value: 0.000006, Wilcoxon rank-sum test).ConclusionsDorsal stress radiography is a reliable, simple procedure to evaluate DRUJ instability intraoperatively. UTR value from dorsal stress radiography could be useful for evaluating DRUJ instability associated with distal radius fracture.     

Ulnar styloid process nonunion and outcome in patients with a distal radius fracture: A meta-analysis of comparative clinical trials

PurposeThere is no consensus on the relation between ulnar styloid process nonunion and outcome in patients with distal radius fractures. The aim of this study was to analyze whether patient-reported outcome is influenced by the nonunion of the accompanying ulnar styloid fracture in distal radius fracture patients.MethodsA meta-analysis of published studies comparing outcomes after distal radius fractures with a united versus a non-united ulnar styloid process was performed. In addition, if provided by the authors, the raw data of these studies were pooled and analysed as one study. The outcome measures of the analyses included patient-reported outcome, functional outcome, grip-strength, pain, and distal radioulnar joint (DRUJ) instability.ResultsData from six comparative studies were included, concerning 365 patients with a distal radius fracture. One hundred and thirty-five patients with an ulnar styloid union were compared with 230 patients with a nonunion of the ulnar styloid. No significant differences were found between groups regarding any outcome measure.ConclusionBased on this meta-analysis, there is no relation between the nonunion of the ulnar styloid process and function in patients with a distal radius fracture.     

Isolated radial shaft fractures are more common than Galeazzi fractures

PURPOSE: In contrast to isolated diaphyseal fractures of the ulna (so-called night-stick fractures), isolated fractures of the radial diaphysis generally are expected to have associated injury of the distal radioulnar joint (DRUJ), the so-called Galeazzi fracture. This study retrospectively reviewed isolated fractures of the radial diaphysis in a large cohort of patients to determine how often such fractures occur without DRUJ injury METHODS: Thirty-six patients with fracture of the radius without fracture of the ulna were followed up for at least 6 months after injury. Injury of the DRUJ was defined as more than 5 mm of ulnar-positive variance on radiographs taken before any manipulative or surgical reduction. All of the fractures were treated with plate and screw fixation (8 with autogenous bone grafting) and all healed. Patients with DRUJ injury had either temporary pinning or immobilization of the DRUJ or surgical fixation of a large ulnar styloid fracture. Patients without DRUJ injury were mobilized within 2 weeks. RESULTS: Nine patients had dislocation of the DRUJ, 4 with large ulnar styloid fractures. Among the remaining 27 patients 1 had displacement of the proximal radioulnar joint noted after surgery, leading to a secondary procedure for radial head resection. The functional results were satisfactory or excellent in all but 2 patients with functional limitations related to central nervous system injury. No patient had DRUJ dysfunction at the final follow-up evaluation. CONCLUSIONS: Isolated fractures of the radial diaphysis are more common than true Galeazzi fractures. Surgeons should take great care not to overlook injury to the distal or proximal radioulnar joint in association with isolated diaphyseal fractures of the radius; however, fractures without identifiable radioulnar disruption can be treated without specific treatment of the DRUJ and with immediate mobilization. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic, Level IV.

Does concomitant ulnar styloid fracture and distal radius fracture portend poorer outcomes? A meta-analysis of comparative studies

PurposeAn ulnar styloid fracture often occur in association with a distal radial fracture. Whether an ulnar styloid fracture interfere with the results of a distal radial fracture still remains controversial. The aim of this study was to analyse the effects of an accompanying ulnar styloid fracture on clinical outcomes in patients with distal radial fractures.MethodsA meta-analysis of published studies comparing outcomes of distal radial fractures with an ulnar styloid fracture versus isolated distal radial fractures was performed. Outcomes of function results, radiological evaluation, and patient reported scores were analyzed.ResultsTen studies including 1403 distal radius fractures were identified fitting inclusion criteria. There was no significant difference in wrist motion, grip strength, radial height, volar angle, ulnar variance, pain score, PRWE score, or SF-36 score for distal radial fractures associated with an ulnar styloid fracture versus isolated distal radial fractures. In final follow up, patients with associated an ulnar styloid fracture had lower radial inclination and higher DASH scores. But there was no significant clinical difference. In addition, we found there was no significant difference of outcomes between union and non-union ulnar styloid fractures.ConclusionsBased on this meta-analysis, we suggest that an associated ulnar styloid fracture does not affect the outcomes of a distal radial fracture and clinicians should be caution in electing operative treatment for patients with an ulnar styloid fracture.     

Comparison of united and nonunited fractures of the ulnar styloid following volar-plate fixation of distal radius fractures

Introduction

The purpose of this study was to determine whether associated nonunion of ulnar styloid fracture following plate-and-screw fixation of a distal radius fracture (DRF) has any effect on wrist functional outcomes, ulnar-sided wrist pain or distal radioulnar joint (DRUJ) instability.

Materials and methods

A total of 91 consecutive patients with a DRF and an accompanying ulnar styloid fracture treated by open reduction and volar locking plate fixation were included in this study. In the first part of the analysis, the 91 study subjects were subdivided according to the presence or not of ulnar styloid union (20 and 71, respectively) by radiography at final follow-up (average 23 months). These two cohorts were compared with respect to wrist functions at 3 months postoperatively and the final follow-up visit, and ulnar-sided wrist pain and DRUJ instability at the final follow-up visit and ulnar styloid length as determined radiographically at final follow-up. In the second part of the analysis, 49 of the 91 study subjects with an ulnar styloid base fracture were subdivided according to the presence or not of ulnar styloid base fracture union (12 and 37, respectively) at final follow-up by radiography. These two groups were also compared with respect to the above-mentioned parameters.

Results

Ulnar styloid fractures united in 20 (22%) of the 91 patients at final follow-up visit (average 23 months). No significant differences were found at any time during follow-up between patients who achieved or did not achieve ulnar styloid fracture union or ulnar styloid base fracture union.

Conclusion

Ulnar styloid nonunion does not appear to affect wrist functional outcomes, ulnar-sided wrist pain or DRUJ stability, at least when a DRF is treated by open reduction and volar plate fixation.     

Size and stabilization of the dorsoulnar fragment in AO C3-type distal radius fractures

IntroductionVolar locking plate (VLP) fixation has become the gold-standard treatment for distal radius fractures (DRFs). Especially, internal fixation of the volar lunate facet fragment is essential for the treatment of AO C3-type DRFs. On the other hand, the necessity of the fixation of the dorsal lunate facet fragment (dorsoulnar fragment) remains unclear. The purpose of the present study was to measure three-dimensionally the size of the dorsoulnar fragments in AO C3-type DRFs using computed tomography (CT) images in detail, and to reveal relationships of the size and stabilization of the dorsoulnar fragment with postoperative fracture displacement after VLP fixation.Materials and methodsWe retrospectively reviewed the 101 consecutive Japanese patients who underwent surgical treatment for AO C3-type distal radius fractures. If patient had dorsoulnar fragment, the three-dimensional size of this fragment and the occupying ratio to the radiocarpal joint (RCJ) and the distal radioulnar joint (DRUJ) were anatomically evaluated using the preoperative CT images. In addition, we investigated the relationship of the size and stabilization of the dorsoulnar fragment with fracture displacement after VLP fixation. We statistically compared the size parameters and occupying ratio of the dorsoulnar fragment between the displaced group and the stable groups using a two-tailed t-test. We also statistically compared the numbers of screws inserted into the dorsoulnar fragments between the displaced and stable groups using a chi-square test.ResultsThe mean dorsoulnar fragment size was 9.4 mm × 7.9 mm × 11.0 mm and the occupying ratio to the DRUJ and RCJ was 50% and 10%, respectively. The number of patients treated with volar locking plate fixation was 77, of which 12 patients had postoperative displacements. Although the size of the dorsoulnar fragment was not associated with postoperative displacement, stabilization following screw insertion into the dorsoulnar fragment was significantly associated with displacement.ConclusionStabilization of the dorsoulnar fragment with at least one screw of the volar locking plate was necessary to prevent postoperative fracture displacement regardless of dorsoulnar fragment size in AO C3-type distal radius fractures.     

Distal radius fractures: a comparison of tension band wiring versus ulnar outrigger external fixation for the management of distal radioulnar instability

PURPOSE: To retrospectively compare the results of immobilization of the forearm in supination with the results of tension band fixation of the ulnar styloid in 35 patients with distal radius fractures, fracture of the base of the ulnar styloid, and distal radioulnar joint instability treated with external fixation. METHODS: Thirty-five patients with fractures of the distal radius, fracture of the base of the ulnar styloid, and unstable distal radioulnar joint had external fixation with adjunctive percutaneous pins and allograft bone to reduce and stabilize the distal radius fracture anatomically. Only those patients with an associated ulnar styloid base fracture displaced over 2 mm with gross distal radioulnar joint instability relative to the contralateral wrist were included in this study. Group 1 consisted of patients in whom the ulnar styloid base fracture was treated with conventional tension band wiring techniques. Group 2 patients were treated with a supplemental outrigger from the external fixator to the ulna and locked in 60 degrees of forearm supination. Groups 1 and 2 had an average follow-up period of 40 and 36 months, respectively. RESULTS: Group 2 had significantly better supination than group 1. In terms of functional outcome it was found that there was no significant difference for the Disabilities of the Arm, Shoulder, and Hand and the Gartland and Werley scores between the 2 treatment groups. There was a lower rate of complications and fewer secondary procedures were required in group 2. The incidence of distal ulna resection was 4 of the 35 patients (2 patients in each group). CONCLUSIONS: Our results indicate that patients in whom the ulnar styloid can be reduced and maintained in supination can be treated effectively with fixed supination outrigger external fixation. This method resulted in a statistically significant improvement in supination and a lower rate of distal radioulnar joint complications, and it required fewer secondary procedures.
