Various studies report a correlation between the severity of the primary displacement, carpal malalignment & an expectant loss of reduction over a given time period when treating distal radius fractures with cast immobilization. Recently, studies have attempted to classify carpal malalignments associated with displaced distal radial fractures based on Effective radio-lunate flexion (ERLF) into: midcarpal with ERLF < 250 and radiocarpal malalignment with ERLF > 250. The aim of this study was to assess the frequency of carpal instability as a concomitant lesion to fractures of the distal radius, delineate further various factors including associated carpal malalignment based on ERLF that are predictive of instability based on a timeline of early (one week) and late failure (six weeks) in an attempt to predict the final radiological outcome accurately. Radiographic alignment parameters were compared before and after reduction using paired t-tests and then also analysed in a multiple logistic regression analysis. Early failure group: Regression analysis showed high correlation between the severity of axial shortening before reduction and at one week. Age, gender, presence of dorsal comminution, ulnar styloid fracture, initial dorsal angulation and flattening of radial angle were unreliable in predicting early failure at one week. Late failure group: We found radial shortening, dorsal tilt, presence of dorsal comminution & ERLF > 25 to be significant predictors of adverse radiological outcome at six weeks. Age, Gender, flattening of radial angle, ulnar styloid fracture as factors for secondary displacement when analyzed independently or in combination were not found to be significant predictors of late failure. The incidence of failure was significantly correlated to radiocarpal malalignment pattern in post reduction radiographs (ERLF> 25) and both at one and six weeks when analysed independently or in combination (p< 0.01). Our study reaffirms the need to attention to initial fracture characteristics and highlights the importance of radiocarpal instability pattern on post reduction radiographs as a predictor of late instability. This would allow the surgeon to inform the patient of chance of success with closed treatment and alternative treatment options

The standard of treatment for most fractures of distal radius remains closed reduction and immobilization. It is essential to discern which fracture patterns are more susceptible to failure so that surgical intervention can be considered when an acceptable reduction cannot be achieved or has a risk of secondary displacement. A correlation between the severity of the primary displacement, carpal malalignment & an expectant loss of reduction over a given time period when treating distal radius fractures with cast immobilization is reported. Recently, studies have attempted to classify carpal malalignments associated with displaced distal radial fractures based on Effective radio-lunate flexion (ERLF) into: midcarpal with ERLF < 25 and radio-carpal malalignment with ERLF > 25. The aim of this study was to assess the frequency of carpal instability as a concomitant lesion to fractures of the distal radius, delineate further various factors including associated carpal malalignment based on ERLF that are predictive of instability based on a timeline of early (I week) and late failure (six weeks). Radiographic alignment parameters were compared using paired t-tests and then also analysed in a multiple logistic regression analysis. There was a significant improvement in all the parameters measured (p< 0.01) with mean correction falling within acceptable limits. Early failure group: Regression analysis showed high correlation between the severity of axial shortening before reduction and at six weeks. Age, gender, presence of dorsal comminution and ulnar styloid fracture, initial dorsal angulation and flattening of radial angle were unreliable in predicting early failure at one week. The incidence of failure was significantly correlated to radiocarpal malalignment pattern in post reduction radiographs (ERLF> 25) at one week when analysed independently or in combination(p< 0.01). In the late failure group:Radial shortening, dorsal tilt, presence of dorsal comminution & ERLF > 25 to be significant predictors of adverse radiological outcome. Age, Gender, flattening of radial angle, ulnar styloid fracture, for secondary displacement when analyzed independently or in combination were not found to be significant predictors of failure at 6-week. The incidence of failure was significantly correlated to radiocarpal malalignment pattern in post reduction radiographs (ERLF> 25) and at 6weeks when analysed independently or in combination.(p< 0.01) Our study reaffirms the need to attention to initial fracture characteristics and highlights the importance of radiocarpal instability pattern on post reduction radiographs as a predictor of late instability & anticipate the radiological outcome. This would allow the surgeon to inform the patient of chance of success with closed treatment and alternative treatment options

The aim of this study was to assess patient-based outcome two years following non-operative management of displaced Colles fractures. 100 patients were evaluated at a minimum of two years after displaced Colles fracture. Fractures were reduced under regional anaesthesia and immobilised in a Colles-type cast for five weeks. The fractures were assessed radiographically by measurement of radial angle, dorsal tilt, radial shortening and carpal malalignment at the time of injury, post-manipulation, and after one and five weeks. The fractures were classified according to Frykman classification. A validated patient-based outcome questionnaire, using a visual analogue score, was used to assess outcome at the end of two years. 7 patients had died, 8 patients were unable to complete the questionnaire because of confusion and 5 were lost to follow-up. Complete outcome data were available on 80 patients. The median age was 61 years. The median pain score was 5 (25%-2 and 75%-12, range 0–100). There was loss of reduction, with more than 5° dorsal angulation and/or 5mm radial shortening in 70% cases. We found that age had no effect on patient outcome except that patients over 50 years complained of more finger stiffness The Frykman classification was an important prognostic factor and a higher grade resulted in worse outcome in a number of areas. Dorsal angulation had no significant effect and carpal malalignment correlated with poor visual appearance. Radial angle and radial shortening were both associated with increased complaints of wrist pain and stiffness. This prospective patient based outcome study has demonstrated that patients make a good functional recovery following nonoperative management of Colles fracture. 70% of our patients had a poor radiological outcome but few reported problems with pain and function at 2 years. Extra-articular malunion due to radial angulation and shortening was common and correlated with wrist pain and stiffness at two years. Frykman classification correlated with pain and functional outcome

Natural history studies of scaphoid non-unions focus on symptomatic non-unions. As a consequence, neither the real incidence nor the long-term sequels of asymptomatic scaphoid pseudarthrosis have been sufficiently studied. Three adult patients (38, 40 and 79 years of age) with long-standing asymptomatic scaphoid non-union are presented. The lesions were identified in radiographs taken in the accident and emergency department after new injuries. All patients could recall the initial fracture, which occurred 17.5, 20 and 40 years respectively before the index examination. Although all the patients were heavy manual workers and in two the non-union occurred in their dominant upper extremity, none could recall pain during activities. Radiographic evidence of carpal malalignment and/or arthritis was noted in all patients. At the 3-month follow-up after the new injury all patients remained asymptomatic with only mild limitations in the range of motion. With evolving trends of ORIF in unstable scaphoid fractures, there is need for larger-scale natural history studies that include asymptomatic scaphoid non-unions. Such lesions are currently poorly understood and their treatment (if one is needed) remains unclear

Developments in plate technology have increased interest in the operative fixation of Colles' fracture. The vast majority of patients are treated non-operatively, yet there are few medium or long-term outcome studies. The aim of this study was to evaluate medium-term outcome of a cohort of patients who previously received treatment in a plaster cast. 236 patients entered two previous prospective, randomised control studies comparing closed reduction techniques or plaster cast type. Both studies showed no difference in clinical or radiological outcome between groups. 43% of this cohort had a final dorsal tilt of > 10° and 44% had final radial shortening of >2mm. All patients now have a minimum follow-up of five years and 60 have died. The remaining 176 patients were contacted by post and asked to complete two validated patient-based questionnaires: a modified Patient Evaluation Measure and a quickDASH. 112 replies were received. The mean age of patients is 67 years (range 23 – 91 years). 31 patients are employed and 57 retired. 77% of patients had a quickDASH score of less than 20. 59% of patients never experience wrist pain whilst 8% of patients have daily pain. All Patient Evaluation Measures have shown a median score of 12 or less (0=excellent, 100= terrible). The best score was for pain (median 4; IQR 2-12) and the worst for grip strength (median 12; IQR 4 – 41). No radiological outcome 5 weeks after injury correlated with any outcome score, except for dorsal tilt, which correlated with difficulty with fiddly tasks (p=0.04) and carpal malalignment which correlated with interference with work (p=0.04). In conclusion, our results show a good functional outcome five years after non-operative management of Colles' fracture. A degree of malunion is acceptable and in the light of our results the economic impact of surgery must be evaluated

Objective: Deformity post distal radius fracture can be associated with alterations in carpal kinematics. This study presents a review to detect the prevalence and clinical implications of such deformities and the variables that influence the outcome following osteotomy. Material & Methods: 29 patients with distal radius mal-union, and an average age of 43 yrs, were treated by a single surgeon with a corrective osteotomy. Along with pain scales, wrist motion, and grip strength, pre and post osteotomy radiographs were evaluated. Preoperatively, 18 patients had dorsal deformity, 9 volar and 2 shortening and malrotation alone. 20 patients had carpal malalignment and 9 normal carpal alignment. Results: The average follow up was 21 months. 24 out of 29 radial deformities were corrected to normal. Overall 17 patients had post-op normal carpal alignment. Three groups resulted; Group I: 11 patients with pre and post-op “fixed” deformities. Group II: 8 patients with normal pre and post-op carpal alignment; and Group III: 9 patients with “lax” pre-op malalignment converted to normal post-op. 1 patient was normal pre-op and converted to DISI at post-op. There was no statistically difference in outcome with regard to pain, forearm rotation, wrist extension, patient age or time to surgery between the three groups. There was statistically significant greater wrist flexion in Group II and III compared to Group I. Conclusions: Carpal malalignement post radius osteotomy will have a negative effect on the functional outcome compared to those patients with preoperative carpal deformity, which corrects with radius osteotomy. Knowledge of this association will help advice patients of expected outcomes

Aims

The primary aim of this study is to quantify and compare outcomes following a dorsally displaced fracture of the distal radius in elderly patients (aged ≥ 65 years) who are managed conservatively versus with surgical fixation (open reduction and internal fixation). Secondary aims are to assess and compare upper limb-specific function, health-related quality of life, wrist pain, complications, grip strength, range of motion, radiological parameters, healthcare resource use, and cost-effectiveness between the groups.
