![]() ![]() The investigators propose that the incidence of ulnocarpal complaints following distal radial fracture depends on the presence but not the healing status of an ulnar styloid fracture. The authors encountered significantly higher pain scores (ulnar sided pain p = 0.012), a higher rate of DRUJ instability (p = 0.032), a greater loss of motion and grip strength (p = 0.001), and a poorer clinical outcome in cases with an ulnar styloid fracture, but no differences were apparent when those with healed ulnar styloid fractures or ulnar styloid nonunions were compared (p > 0.05). Forty-six of these developed an ulnar styloid nonunion. One hundred and one, of 200 distal radial fractures, were associated with an ulnar styloid fracture. The patients underwent both clinical and radiological examination and completed two different questionnaires. ![]() Two hundred distal radial fractures, with a mean follow up of 20 months (range 6-49), were divided into three groups according to the presence and healing status of an ulnar styloid fracture. This could be useful to inform the decision regarding surgical fixation of the ulnar styloid fragment in patients with an unstable distal radioulnar joint (DRUJ) or persistent symptoms at the ulnar aspect of the wrist. Initial displacement of the ulnar styloid should be measured in each distal radial fracture with a concomitant ulnar styloid fracture. In contrast, it could be attested, that an initial fragment dislocation of greater than 2.4 mm in the conventional AP radiographs has a significantly lower chance of successful union (p = 0.022). The current investigators demonstrated that the various ulnar styloid fracture patterns have no significant predictive value for ulnar styloid union. Union of the ulnar styloid fracture was evaluated after at least 6 months of follow-up. Furthermore, the initial ulnar styloid displacement was measured in conventional anteroposterior radiographs. They were also classified as per the established Fernández and Frykman classification systems. Initially, they were grouped into six different morphological types based on a novel classification system. In a retrospective radiological study, the authors aimed to detect the influence of fracture morphology on the union rate of ulnar styloid fractures associated with distal radial fractures.Įighty-two out of 101 ulnar styloid fractures were included in the final statistical analysis. The rate of non-union of the ulnar styloid was 77% at final assessment.Īn unrepaired ulnar styloid fracture does not affect the outcome of a distal radius fracture which is fixed by the “augmented” K-wire method. No significant and clinically meaningful differences were found between the groups in clinical (pain, wrist mobility, grip strength, DASH score) and radiological outcomes. ![]() Instability of the distal radioulnar joint was diagnosed in 2 patients with ulnar styloid fracture. The stability of the distal radioulnar joint and the DASH scores were considered to be primary outcome measures. The patients were followed-up at 3 and 6 months. All patients underwent percutaneous, “augmented” K-wire fixation of the distal radius fracture the ulnar styloid fracture was left untreated. ![]() 35 patients had an isolated fracture of the distal radius and 35 had an associated fracture of the ulnar styloid. Our results suggested that the RSI can be used as a predictor of the clinical outcome in patients with distal radius fractures involving the ulnar styloid.Ī prospective study was carried out to compare outcomes after K-wire fixation of distal radius fractures without and with associated ulnar styloid fracture, but without fixation of the styloid fracture.ħ0 patients, 60 women (86%) and 10 men (14%) with a mean age of 63 years were enrolled. We found a significant correlation between the RSI ratio values and the clinical outcomes. The patients with an excellent result had an RSI ratio of less than 5%. In the 44 patients there were clinically 38 excellent, 4 good, and 2 moderate results. The relation between the RSI value and clinical results was then investigated. The styloid fracture was treated conservatively. In all cases, the distal radius fracture was fixed using a volar locking plate. We used this index in 44 patients (28 men and 16 women mean age: 43.2 years range: 24-64 years) with distal radius fractures involving the the ulnar styloid. We devised a radiographic separation index (RSI), to evaluate the displacement of the ulnar styloid. The aim of this retrospective study was to evaluate the relation between a new index we created for the assessment of distal radius fractures involving the ulnar styloid, and the clinical outcome. ![]()
