PURPOSE: It has been studied prognostic factors about secondary displacement after conservative treatment of the distal radius fracture, but each study showed different results. Authors retrospectively evaluated factors known to be involved secondary displacement of the distal radius fracture to determine its significance. METHODS: One hundred eighteen cases of the radiographically unstable distal radius fractures that closed reduction was adequately performed were retrospectively studied and the radiographic images were taken at 1, 2, 3, 4, 6 weeks after closed reduction. During follow-up, dorsal tilt more than 15°, volar tilt more than 20°, ulnar positive variance more than 4 mm, radial length less than 6 mm, radial inclination less than 10° were thought of the loss of reduction. RESULTS: In 41 cases (34.7%), the loss of reduction occurred. Sex, intra-articular fracture, dorsal and volar comminution, concomitant ulnar fracture and involvement of the distal radio-ulnar joint were statistically not significant. Analysis results of the binomial logistic regression model were as follows: age (p=0.003), radial shortening (p=0.010) and ulnar positive variance (p=0.010) were statistically significant as the predictive prognostic factors. Analysis results of the multinomial logistic regression model showed age (p=0.006) as an only statistically significant factor. CONCLUSION: As the predictive prognostic factors for development of secondary displacement after conservative treatment of the unstable distal radius fracture, age was determined as most significant factor. Also radial shortening and ulnar positive variance were thought of the predictive factors for secondary displacement.

Distal radius fracture is one of the most common fractures treated in the orthopedic field. The application of locking plate principle to the distal radius has allowed comminuted distal radius fractures involving the articular surface to be effectively treated by open reduction and internal fixation. The authors experienced a case of failure of distal locking screws in an intraarticular distal radius fracture treated with volar locking plate fixation.

Most distal radius fractures are currently being treated with anterior plating using anatomical precontoured locking compression plates via the anterior approach. However, it is difficult to fix the volar articular marginal fragment because these anatomical plates should be placed proximally to the watershed line. There were just a few methods of fixation for this fragment on medical literature. Herein, we introduced a tension band wiring technique for fixation of a volar articular marginal fragment in the distal radius.

One of the points made against nailing in radius and ulna shaft fractures has been the loss of radial bow and its impact on function. The aims of the study were to assess the change in magnitude and location of the radial bow in radius and ulna shaft fractures treated with intramedullary square nails and to assess the impact of this change on functional outcome, patient reported disability and the range of motion of the forearm. We measured the magnitude of radial bow and its location in the operated extremity and compared it to the uninjured side in 32 adult patients treated with intramedullary square nailing for radius and ulna shaft fractures at our institute. The mean loss of magnitude of maximum radial bow was 2.18 mm which was statistically significant by both student-T test and Mann-Whitney U test with p value less than 0.01. The location of maximum radial bow shifted distally but was statistically insignificant. The magnitude of maximum radial bow had a negative correlation with DASH score that was statistically insignificant (R=- 0.22, p=0.21). It had a positive, statistically significant correlation to the extent of supination in the operated extremity (R = 0.66, p = 0.0004). A loss of up to 2mm of radial bow did not influence the functional outcome as assessed by criteria reported by Anderson et al. The magnitude of radial bow influenced the supination of the forearm but not the final disability as measured by DASH score. Intramedullary nailing did decrease the magnitude of radial bow but a reduction of up to 2mm did not influence the functional outcome.

PURPOSE: To evaluate clinical and radiological results using 3.5 mm & 2.4 mm volar locking compression plate (LCP) in distal radius fractures. MATERIALS AND METHODS: This study reviewed the results of 115 cases of distal radius fractures treated with 3.5 mm volar LCP (73 cases) & 2.4 mm volar LCP (42 cases) from September 2003 to June 2009. The radiographic results were evaluated by radiographic assessment, and the clinical results were evaluated by Knirk and Jupiter's criteria, Modified Mayo wrist scoring system and DASH score. RESULTS: Radiological evaluation of the radial length, radial inclination, volar tilt and intraarticular step off were improved both 3.5 mm volar LCP and 2.4 mm volar LCP. Nine cases of arthritis occured in 3.5 mm volar LCP and 7 cases in 2.4 mm volar by using the Knirk and Jupiter's criteria. The mean score evaluated by Modified Mayo was 86.7 in 3.5 mm volar LCP and 84.8 in 2.4 mm volar LCP. DASH score was 11.2 point in 3.5 mm volar LCP, 10.9 point in 2.4 mm volar LCP. All cases showed bone union showing no evidence of malunion, nounion, nor metal failure. CONCLUSION: Distal radius fractures treated with 3.5 mm volar LCP and 2.4 mm volar LCP show satisfying radiological and clinical outcome.

Distal radioulnar dislocation is commonly associated with radius fracture. Most common dislocation pattern is the dorsal dislocation. We present the unique case of volar dislocation of the distal radioulnar joint blocked by displaced dorsal Barton fracture of distal radius and discuss the injury mechanism and anatomic lesions.

PURPOSE: To analyze the relationship of fracture patterns in cases diagnosed as scapholunate dissociation after treatment for distal radius fracture. MATERIALS AND METHODS: Forty-six cases were analyzed clinically and radiographically. Twenty-four cases were treated by closed reduction and percutaneous k-wire fixation, twelve cases by closed reduction, k-wire and external fixator application, and ten cases by open reduction and plate fixation. For radiological evaluation, scapholunate gap, scapholunate angle, and radiolunate angle were analyzed to detect scapholunate dissociation and dorsal intercalated segmental instability. RESULTS: In the 7 cases with a borderline scapholunate gap (>2 mm), 3 cases with an initial fracture line involving the interfacet prominence progressed to static scapholunate dissociation. CONCLUSION: Initial scapholunate gap and fracture line geometry of the distal radius were helpful for predicting progression to static scapholunate dissociation

Acute rupture of flexor tendons following distal radius fracture is very rare. We experienced four cases of acute rupture of flexor tendons that were treated surgically. Injured tendons included flexor pollicis longus, flexor carpi radialis, palmaris longus and third flexor digitorum profundus. A severely displaced fracture with a volar spike of the distal radius was detected on plain radiographs in all cases. Ruptures of flexor pollicis longus and third flexor digitorum profundus were diagnosed on preoperative examination but ruptures of other tendons were identified during the operation. Repairs of fractures and ruptured tendons were performed simultaneously and good functional outcomes were achieved.
