Aims. Carpal malalignment after a distal radial fracture occurs due to loss of volar tilt. Several studies have shown that this has an adverse influence on function. We aimed to investigate the magnitude of dorsal tilt that leads to carpal malalignment, whether reduction of dorsal tilt will correct carpal malalignment, and which measure of carpal malalignment is the most useful. Methods. Radiographs of patients with a distal radial fracture were prospectively collected and reviewed. Measurements of carpal malalignment were recorded on the initial radiograph, the radiograph following reduction of the fracture, and after a further interval. Linear regression modelling was used to assess the relationship between dorsal tilt and carpal malalignment. Receiver operating characteristic (ROC) analysis was used to identify which values of dorsal tilt led to carpal malalignment. Results. A total of 250 consecutive patients with 252 distal radial fractures were identified. All measures of carpal alignment were significantly associated with dorsal tilt at each timepoint. This relationship persisted after adjustment for age, sex, and the position of the wrist. Capitate shift consistently had the strongest relationship with dorsal tilt and was the only parameter that was not influenced by age or the position of the wrist. ROC curve analysis identified that abnormal capitate shift was seen with > 9° of dorsal tilt. Conclusion. Carpal malalignment is related to dorsal tilt following a distal radial fracture. Reducing the fracture and improving dorsal tilt will reduce carpal malalignment. Capitate shift is easy to assess visually, unrelated to age and sex, and appears to be the most useful measure of carpal malalignment. The aim during reduction of a distal radial fracture should be to realign the capitate with the axis of the radius and prevent carpal malalignment.

Objectives. The patient-rated wrist evaluation (PRWE) and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire are patient-reported outcome measures (PROMs) used for clinical and research purposes. Methodological high-quality clinimetric studies that determine the measurement properties of these PROMs when used in patients with a distal radial fracture are lacking. This study aimed to validate the PRWE and DASH in Dutch patients with a displaced distal radial fracture (DRF). Methods. The intraclass correlation coefficient (ICC) was used for test-retest reliability, between PROMs completed twice with a two-week interval at six to eight months after DRF. Internal consistency was determined using Cronbach’s α for the dimensions found in the factor analysis. The measurement error was expressed by the smallest detectable change (SDC). A semi-structured interview was conducted between eight and 12 weeks after DRF to assess the content validity. Results. A total of 119 patients (mean age 58 years (. sd. 15)), 74% female, completed PROMs at a mean time of six months (. sd. 1) post-fracture. One overall meaningful dimension was found for the PRWE and the DASH. Internal consistency was excellent for both PROMs (Cronbach’s α 0.96 (PRWE) and 0.97 (DASH)). Test-retest reliability was good for the PRWE (ICC 0.87) and excellent for the DASH (ICC 0.91). The SDC was 20 for the PRWE and 14 for the DASH. No floor or ceiling effects were found. The content validity was good for both questionnaires. Conclusion. The PRWE and DASH are valid and reliable PROMs in assessing function and disability in Dutch patients with a displaced DRF. However, due to the high SDC, the PRWE and DASH are less useful for individual patients with a distal radial fracture in clinical practice. Cite this article: Y. V. Kleinlugtenbelt, R. G. Krol, M.

Aims. The aim of this study was to compare patient-reported outcome measures (PROMs) and the Single Assessment Numerical Evaluation (SANE) score in patients treated with a volar locking plate for a distal radial fracture. Methods. This study was a retrospective review of a prospective database of 155 patients who underwent internal fixation with a volar locking plate for a distal radial fracture between August 2014 and April 2017. Data which were collected included postoperative PROMs (Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH) and Patient-Rated Wrist Evaluation (PRWE)), and SANE scores at one month (n = 153), two months (n = 155), three months (n = 144), six months (n = 128), and one year (n = 73) after operation. Patients with incomplete data were excluded from this study. Correlation and agreement between PROMs and SANE scores were evaluated. Subgroup analyses were carried out to identify correlations according to variables such as age, the length of follow-up, and subcategories of the PRWE score. Results. The Pearson correlation coefficient (r) between PROMs and SANE scores was -0.76 (p < 0.001) for DASH and -0.72 (p < 0.001) for PRWE, respectively. Limits of agreement between PROMs and ‘100-SANE’ scores were met for at least 93% of the data points. In subgroup analysis, there were significant negative correlations between PROMs and SANE scores for all age groups and for follow-up of more than six months. The correlation coefficient between PRWE subcategories and SANE score was -0.67 (p < 0.001) for PRWE pain score and -0.69 (p < 0.001) for PRWE function score, respectively. Conclusion. We found a significant correlation between postoperative SANE and PROMs in patients treated with a volar locking plate for a distal radial fracture. The SANE score is thus a reliable indicator of outcome for patients who undergo surgical treatment for a radial fracture. Cite this article: Bone Joint J 2020;102-B(6):744–748

Aims. The aim of this study was to test the null hypothesis that there is no difference, from the payer perspective, in the cost of treatment of a distal radial fracture in an elderly patient, aged > 65 years, between open reduction and internal fixation (ORIF) and closed reduction (CR). Materials and Methods. Data relating to the treatment of these injuries in the elderly between January 2007 and December 2015 were extracted using the Humana and Medicare Advantage Databases. The primary outcome of interest was the cost associated with treatment. Secondary analysis included the cost of common complications. Statistical analysis was performed using a non-parametric t-test and chi-squared test. Results. Our search yielded 8924 patients treated with ORIF and 5629 patients treated with CR. The mean cost of an uncomplicated ORIF was more than a CR ($7749 versus $2161). The mean additional cost of a complication in the ORIF group was greater than in the CR group ($1853 versus $1362). Conclusion. These findings show that there are greater payer fees associated with ORIF than CR in patients aged > 65 years with a distal radial fracture. CR may be a higher-value intervention in these patients. Cite this article: Bone Joint J 2018;100-B:205–11

Displaced fractures of the distal radius in children are usually reduced under sedation or general anaesthesia to restore anatomical alignment before the limb is immobilized. However, there is growing evidence of the ability of the distal radius to remodel rapidly, raising doubts over the benefit to these children of restoring alignment. There is now clinical equipoise concerning whether or not young children with displaced distal radial fractures benefit from reduction, as they have the greatest ability to remodel. The Children’s Radius Acute Fracture Fixation Trial (CRAFFT), funded by the National Institute for Health and Care Research, aims to definitively answer this question and determine how best to manage severely displaced distal radial fractures in children aged up to ten years.

Objectives. Patient-reported outcome measures (PROMs) are often used to evaluate the outcome of treatment in patients with distal radial fractures. Which PROM to select is often based on assessment of measurement properties, such as validity and reliability. Measurement properties are assessed in clinimetric studies, and results are often reviewed without considering the methodological quality of these studies. Our aim was to systematically review the methodological quality of clinimetric studies that evaluated measurement properties of PROMs used in patients with distal radial fractures, and to make recommendations for the selection of PROMs based on the level of evidence of each individual measurement property. Methods. A systematic literature search was performed in PubMed, EMbase, CINAHL and PsycINFO databases to identify relevant clinimetric studies. Two reviewers independently assessed the methodological quality of the studies on measurement properties, using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. Level of evidence (strong / moderate / limited / lacking) for each measurement property per PROM was determined by combining the methodological quality and the results of the different clinimetric studies. Results. In all, 19 out of 1508 identified unique studies were included, in which 12 PROMs were rated. The Patient-rated wrist evaluation (PRWE) and the Disabilities of Arm, Shoulder and Hand questionnaire (DASH) were evaluated on most measurement properties. The evidence for the PRWE is moderate that its reliability, validity (content and hypothesis testing), and responsiveness are good. The evidence is limited that its internal consistency and cross-cultural validity are good, and its measurement error is acceptable. There is no evidence for its structural and criterion validity. The evidence for the DASH is moderate that its responsiveness is good. The evidence is limited that its reliability and the validity on hypothesis testing are good. There is no evidence for the other measurement properties. Conclusion. According to this systematic review, there is, at best, moderate evidence that the responsiveness of the PRWE and DASH are good, as are the reliability and validity of the PRWE. We recommend these PROMs in clinical studies in patients with distal radial fractures; however, more clinimetric studies of higher methodological quality are needed to adequately determine the other measurement properties.

Aims. The aim of this study was to investigate the difference in functional outcome after repair and non-repair of the pronator quadratus muscle in patients undergoing surgical treatment for a distal radial fracture with volar plating. Patients and Methods. A total of 72 patients with a distal radial fracture were included in this randomized clinical trial. They were allocated to have the pronator quadratus muscle repaired or not, after volar locked plating of a distal radial fracture. The patients, the assessor, the primary investigator, and the statistician were blinded to the allocation. Randomization was irreversibly performed using a web application that guaranteed a secure and tamper-free assignment. The primary outcome measure was the Patient Rated Wrist Evaluation (PRWE) after 12 months. Secondary outcomes included the Disabilities of the Arm, Shoulder and Hand (DASH) score, pronation strength, grip strength, the range of pronation and supination, complications, and the operating time. Results. Of the 72 patients, 63 (87.5%) completed follow-up for the primary outcome measure: 31 (86.1%) from the non-repair group and 32 (88.9%) from the repair group. At the 12-month follow-up, the mean difference in PRWE of 5.47 (95% confidence interval (CI) -4.02 to 14.96) between the repair (mean 18.38 (95% CI 10.34 to 26.41)) and non-repair group (mean 12.90 (95% CI 7.55 to 18.25)) was not statistically significant (p = 0.253). There was a statistically significant difference between pronation strength, favouring non-repair. We found no difference in the other secondary outcomes. Conclusion. We found that repairing pronator quadratus made no difference to the clinical outcome, 12 months after volar plating of a distal radial fracture. We conclude that there is no functional advantage in repairing this muscle under these circumstances and advise against it. Cite this article: Bone Joint J 2019;101-B:1498–1505

Aims. The management of completely displaced fractures of the distal radius in children remains controversial. This study evaluates the outcomes of surgical and non-surgical management of ‘off-ended’ fractures in children with at least two years of potential growth remaining. Methods. A total of 34 boys and 22 girls aged 0 to ten years with a closed, completely displaced metaphyseal distal radial fracture presented between 1 November 2015 and 1 January 2020. After 2018, children aged ten or under were offered treatment in a straight plaster or manipulation under anaesthesia with Kirschner (K-)wire stabilization. Case notes and radiographs were reviewed to evaluate outcomes. In all, 16 underwent treatment in a straight cast and 40 had manipulation under anaesthesia, including 37 stabilized with K-wires. Results. Of the children treated in a straight cast, all were discharged with good range of mo (ROM). Five children were discharged at six to 12 weeks with no functional limitations at six-month follow-up. A total of 11 children were discharged between 12 and 50 weeks with a normal ROM and radiological evidence of remodelling. One child had a subsequent diaphyseal fracture proximal to the original injury four years after the initial fracture. Re-displacement with angulation greater than 10° occurred for 17 children who had manipulation under anaesthesia. Four had a visible cosmetic deformity at discharge and nine had restriction of movement, with four requiring physiotherapy. One child developed over- granulation at the pin site and one wire became buried, resulting in a difficult retrieval in clinic. No children had pin site infections. Conclusion. Nonoperative management of completely displaced distal radial fractures in appropriately selected cases results in excellent outcomes without exposing the child to the risks of surgery. This study suggests that nonoperative management of these injuries is a viable and potentially underused strategy. Cite this article: Bone Joint J 2021;103-B(5):902–907

Aims. The aim of this study was to investigate whether intraoperative 3D fluoroscopic imaging outperforms dorsal tangential views in the detection of dorsal cortex screw penetration after volar plating of an intra-articular distal radial fracture, as identified on postoperative CT imaging. Methods. A total of 165 prospectively enrolled patients who underwent volar plating for an intra-articular distal radial fracture were retrospectively evaluated to study three intraoperative imaging protocols: 1) standard 2D fluoroscopic imaging with anteroposterior (AP) and elevated lateral images (n = 55); 2) 2D fluoroscopic imaging with AP, lateral, and dorsal tangential views images (n = 50); and 3) 3D fluoroscopy (n = 60). Multiplanar reconstructions of postoperative CT scans served as the reference standard. Results. In order to detect dorsal screw penetration, the sensitivity of dorsal tangential views was 39% with a negative predictive value (NPV) of 91% and an accuracy of 91%; compared with a sensitivity of 25% for 3D fluoroscopy with a NPV of 93% and an accuracy of 93%. On the postoperative CT scans, we found penetrating screws in: 1) 40% of patients in the 2D fluoroscopy group; 2) in 32% of those in the 2D fluoroscopy group with AP, lateral, and dorsal tangential views; and 3) in 25% of patients in the 3D fluoroscopy group. In all three groups, the second compartment was prone to penetration, while the postoperative incidence decreased when more advanced imaging was used. There were no penetrating screws in the third compartment (extensor pollicis longus groove) in the 3D fluoroscopy groups, and one in the dorsal tangential views group. Conclusion. Advanced intraoperative imaging helps to identify screws which have penetrated the dorsal compartments of the wrist. However, based on diagnostic performance characteristics, one cannot conclude that 3D fluoroscopy outperforms dorsal tangential views when used for this purpose. Dorsal tangential views are sufficiently accurate to detect dorsal screw penetration, and arguably more efficacious than 3D fluoroscopy. Cite this article: Bone Joint J 2020;102-B(7):874–880

Aims. There is no level I evidence dealing with the optimal period of immobilization for patients with a displaced distal radial fracture following closed reduction. A shorter period might lead to a better functional outcome due to less stiffness and pain. The aim of this study was to investigate whether this period could be safely reduced from six to four weeks. Methods. This multicentre randomized controlled trial (RCT) included adult patients with a displaced distal radial fracture, who were randomized to be treated with immobilization in a cast for four or six weeks following closed reduction. The primary outcome measure was the Patient-Rated Wrist Evaluation (PRWE) score after follow-up at one year. Secondary outcomes were the abbreviated version of the Disability of Arm, Shoulder and Hand (QuickDASH) score after one year, the functional outcome at six weeks, 12 weeks, and six months, range of motion (ROM), the level of pain after removal of the cast, and complications. Results. A total of 100 patients (15 male, 85 female) were randomized, with 49 being treated with four weeks of immobilization in a cast. A total of 93 completed follow-up. The mean PRWE score after one year was 6.9 (SD 8.3) in the four-week group compared with 11.6 (SD 14.3) in the six-week group. However, this difference of -4.7 (95% confidence interval -9.29 to 0.14) was not clinically relevant as the minimal clinically important difference of 11.5 was not reached. There was no significant difference in the ROM, radiological outcome, level of pain, or complications. Conclusion. In adult patients with a displaced and adequately reduced distal radial fracture, immobilization in a cast for four weeks is safe, and the results are similar to those after a period of immobilization of six weeks.

The osteoinductive properties of demineralised bone matrix have been demonstrated in animal studies. However, its therapeutic efficacy has yet to be proven in humans. The clinical properties of AlloMatrix, an injectable calcium-based demineralised bone matrix allograft, were studied in a prospective randomised study of 50 patients with an isolated unstable distal radial fracture treated by reduction and Kirschner (K-) wire fixation. A total of 24 patients were randomised to the graft group (13 men and 11 women, mean age 42.3 years (20 to 62)) and 26 to the no graft group (8 men and 18 women, mean age 45.0 years (17 to 69)). At one, three, six and nine weeks, and six and 12 months post-operatively, patients underwent radiological evaluation, assessments for range of movement, grip and pinch strength, and also completed the Disabilities of Arm, Shoulder and Hand questionnaire. At one and six weeks and one year post-operatively, bone mineral density evaluations of both wrists were performed. No significant difference in wrist function and speed of recovery, rate of union, complications or bone mineral density was found between the two groups. The operating time was significantly higher in the graft group (p = 0.004). Radiologically, the reduction parameters remained similar in the two groups and all AlloMatrix extraosseous leakages disappeared after nine weeks. This prospective randomised controlled trial did not demonstrate a beneficial effect of AlloMatrix demineralised bone matrix in the treatment of this category of distal radial fractures treated by K-wire fixation.

Distal radial fractures are amongst the most common trauma referrals, however controversy remains regarding their optimum management. We undertook a retrospective review of the management of distal radial fractures in our department. The prospectively maintained trauma database was used to identify patients admitted for operative management of a dorsally displaced distal radial fracture between June 2008 and June 2009. Only extra-articular or simple intra-articular fractures were included (AO classification A2/A3/C1/C2). Operation notes were reviewed to determine the method of fixation. Patients were contacted by post and asked to complete a functional outcome score - Disabilities of the Arm, Shoulder and Hand (DASH). A further 12 patients with similar fractures who had been managed conservatively were also asked to complete a DASH score to provide a comparison between operative and non-operative management. 98 patients were identified - 67 female, 31 male. Mean age was 51 years, range 15-85 years. All patients were at least 1 year post-op. 26 patients had manipulation under anaesthesia (MUA). 48 patients had MUA and K-wire fixation, which was supplemented with synthetic bone substitute in 16 cases. 3 patients had MUA and bone graft and 21 patients had open reduction and internal fixation (ORIF) with a volar plate. 34 correctly completed DASH scores were returned. A lower score equates to a better functional outcome. Mean DASH scores were: MUA 14.8; MUA+K-wire 13.1; ORIF 13.6; conservative 47.1. This data would indicate that patients with a significantly displaced distal radial fracture have a better functional outcome with operative management to improve the fracture alignment. However, all of the methods of fixation used resulted in similar functional outcomes at one year

Introduction. The distal radius is the most frequently fractured bone in the forearm with an annual fracture incidence in the UK of about 9–37 in 10,000. Restoration of normal anatomy is an important factor that dictates the final functional outcome. A number of operative options are available, including Kirschner wiring, bridging or non-bridging external fixation and open reduction and internal fixation by means of dorsal, radial or volar plates. We designed this study to analyse the clinical and radiological outcome of distal radial fracture fixation using volar plating. Materials/Methods. Thirty-seven patients with distal radius fractures undergoing open reduction and internal fixation using volar plates were included. Tilt of the fractured distal radial fragment was recorded from the initial radiograph and classification of fractures was done using the Orthopaedic Trauma Association system. The QuickDASH questionnaire was used for evaluation of symptomatic and functional outcome six months to one year after surgery. The radiological outcome was assessed using measurements of radial inclination, ulnar variance and volar tilt. Of the thirty-seven patients, 13 were male and 24 were female. The mean age was 55.6 years (range 18–87 years). According to the AO classification, there were 8 cases each of C2 and C3 fractures, 6 cases of C1 fractures and 3 cases each of class A2, A3, B1 and B3 fractures. There were 2 patients with class B2 fracture. Results. Post-operatively, the average restoration of volar tilt was 6.47 degrees (range −12.4 to 20.3 degrees). Mean restoration of radial inclination was 23 degrees (range 12.5 to 30.0 degrees). Ulnar variance on average was 0.09 mm (range −5.0–6.7mm). The mean QuickDASH score was 9.8. Conclusion. The results of this study indicate that fixation of displaced intra- and extra-articular distal radial fractures is achieved satisfactorily with restoration of both normal anatomy and function using volar plates

Older fracture patients frequently ask whether their osteoporosis will affect fracture healing. There is only limited previous data about this. We investigated recovery after distal radial fracture, and compared it with BMD of the other distal radius and the lumbar spine (measured using quantitative CT). All 28 patients had sustained a dorsally displaced distal radial fracture which was deemed to require treatment by intrafocal wire fixation. All patients had acceptable correction of dorsal and radial angle at final x ray (3 months). Wrist function was measured using the Patient Rated Wrist Evaluation (PRWE – a validated outcome measure for use after distal radial fractures), grip strength,and range of motion. All measurements were made at 6, 12 and 26 weeks. BMD was measured in the opposite wrist and the lumbar spine using QCT at 6 weeks after fracture. There was no correlation between recovery of grip strength (% of contralateral grip strength) at 6,12,or 26 weeks with BMD at either site. Similarly, there was no correlation between BMD and either absolute PRWE scores at any time point or improvement in PRWE between time points. The strongest predictor of recovery of grip appeared to be the proportion of grip recovered at 6 weeks (correlation between% grip recovered at 6 weeks and 3 months r = 0.85; at 6 weeks and 6 months r= 0.56; both p < 0.001). This was not affected by age or variations in measured final dorsal or radial angles or length within this group. It was not affected by degree of preoperative fracture displacement. These data suggest that recovery of function after distal radial fractures is not influenced by osteoporosis. The data about the importance of initial recovery of grip suggest that factors other than bone position and bone healing may affect rate of functional recovery after distal radial fracture

Purpose. Distal metaphyseal radial fractures are common in the paediatric population and the management of these fractures is controversial. The incidence of re-displacement in the closed management of these fractures is as much as 30% in some studies. Various methods have been described with the view to predict fracture displacement of distal radial fractures in children. One of these indices is the three point index (TPI). This index seeks to assess the adequacy of 3 point moulding and thus predict fracture displacement. It is a calculated ratio that if above 0.8 states that there is an increased risk of fracture re-displacement. The purpose of this study is to assess the accuracy of this index in predicting displacement of distal radial fractures in children. Methods. This retrospective study included 65 patients of both sexes under the age of 13 for a period of one year from January 2011 to January 2012. All patients with a dorsally displaced fracture of the distal radius were included. 22 patients were excluded because of loss to follow-up or absence of a complete series of x-rays. All patients were taken to theatre for a general anaesthetic and manipulation of their fractures using an image intensifier to confirm reduction. X-rays of initial fracture displacement, post manipulation position and follow-up fracture position at 2 and 6 weeks were assessed. The sensitivity, specificity, negative and positive predictive values of the TPI in screening for fracture re-displacement were calculated. Results. Of the 43 patients included in the study, 93% of patients had an anatomical reduction in theatre with an average TPI of 1. Nineteen patients suffered significant displacement from 2 to 6 weeks postoperatively. We found that the TPI in our study had a sensitivity of 84%, a specificity of 37%, a negative predictive value of 75% and a positive predictive value of 51%. Conclusion. We found the TPI to be a useful screening tool of later displacement for the closed management of distal metaphyseal radius fractures. NO DISCLOSURES

Distal radial fractures are common in children. Recent outcome studies have cast doubt on the success of treatment by closed reduction and application of plaster. The most important risk factor for poor outcome is translation of the fracture. If a distal radial fracture is displaced by more than half the diameter of the bone at the fracture site it should be classified as high risk. We performed percutaneous Kirschner-wire pinning on 157 such high-risk distal radial fractures in children under 16 years of age. The predicted early and late failure rate was reduced from 60% to 14% and only 1.5% of patients had significant limitation of forearm movement of more than 15 degrees in the final assessment at a mean of 31 months after operation. There were no cases of early physeal closure or deep infection

Distal radial fractures represent 17% of fractures in the Italian E.R. In the last years many different techniques accompanied the traditional treatment of closed reduction and cast immobilization such as closed reduction + pinning + cast, “epi-block” fixation, ORIF with dorsal and/or volar plates, screws and external fixation. These techniques are mostly followed by a period of immobilization with cast which is optional in A.O. type A fractures and is usually necessary in type B and C fractures. At the University Hospital “Policlinico Umberto I” of Rome E.R. we have started treating these fractures with a new fixation system which we projected. This system provides a non-bridging external fixation. The synthesis is guaranteed by two or more K-wires which can be intramedullary or x-crossing the cortex and/or inter-fragmentary. These K-wires are connected with two radial pins by an external bar. This radial to radial system gives stability to the fracture and allows the patient to move the wrist immediately. We remove this fixation system after 40 days. From July 2008 to August 2009 we treated 56 distal radial fractures. Clinical assessment was performed every seven days until removal of external fixation system, then at 2, 3, 6 and 12 months. Radiographic assessment was performed at 30 and 40 days, consequently at 2, 3, 6 and 12 months. Outcome was measured on the basis of range of motion, grip and pinch strength, DASH and PRWE scores. A questionnaire was used to determine patient satisfaction, and a detailed analysis of complications was carried out. All patients had excellent or good results and were satisfied with the clinical outcome. At 60 days after surgery 90% of patients demonstrated complete clinical and functional recovery. After 3 months 100% of patients demonstrated complete clinical and functional recovery. After 6 months and 12 months no modification of the obtained result was detected

We reviewed a series of 79 distal radial fractures with volar displacement which had been fixed internally using a buttress plate. The fractures were classified using the Frykman and AO systems; 59% were intraarticular. Complications occurred in 40.5% of cases; malunion was most frequent (28%). Functional recovery in patients with malunion was significantly worse than in those with good anatomical restoration (p < 0.001). The AO and Frykman classifications and the degree of restoration of volar tilt were predictive of outcome

Aims: To detect discriminant features in the cyclic kinematic patterns generated during selected upper limb activities of daily living by a normative and a distal radial fracture group, so as to reduce the multidimensionality of the kinematic analysis. Methods: Cyclic activities of daily living were performed using a protocol that allowed comparison between the resulting kinematic patterns or waveforms. Twop groups were measured:. Group A: 11 subjects with normal hand function (average age: 31.5ys, SD: 8.7ys). Group B: 5 subjects having undergone treatment for distal radial fracture was tested using the same methods (average age: 34.2ys, SD: 16.8ys). Task presented here, (one of 5) performed by turning a key 90 degrees clockwise. Principal component analysis (PCA) was applied to the waveforms of group A, using the procedure illustrated by Deluzio et al.,1997 for use with walking gait patterns. A 90% trace criterion was used to calculate the number of principal components (PCs) to retain. Results: Looking at elbow pronation/supination (PS). Two PCs were retained. The first component consisted of a simple pronation pattern. The opposite signs of Y1 differentiated left-hand users (utmost right), who required pronation to rotate the key, from right-hand ones, who required supination, with the exception of subject 3 group B. The second component consisted of pronation (cycle first half) followed by supination (second half). Subject 3 stood out because of limited elbow supination, which resulted from the combination of pronation (Y1) and supination (Y2) components. Conclusions: Upper limb analysis can employ the statistic tools of gait analysis provided a cyclic and repeatable protocol is used. PCA was applied to elbow PS to identify statistically different movements of the distal radial fracture group and underline their main characteristics. This is particularly important in the presence of a large data group, when the identification and evaluation processes need to be both rapid and accurate. Limited PS was identified as a discriminant feature, supporting the follow-up studies for this injury that measured a reduction of PS by about 80% compared to that of the unaffected side. The cycle stages concerned can be identified on the basis of the contribution given by each component

We compared the ceiling effects of two patient-rating scores, the Disability of the Arm, Shoulder and Hand (DASH) and Patient-Rated Wrist Evaluation (PRWE), and a physician-rating score, the Modified Mayo Wrist Score (MMWS) in assessing the outcome of surgical treatment of an unstable distal radial fracture. A total of 77 women with a mean age of 64.2 years (50 to 88) who underwent fixation using a volar locking plate for an unstable distal radial fracture between 2011 and 2013 were enrolled in this study. All completed the DASH and PRWE questionnaires one year post-operatively and were assessed using the MMWS by the senior author. The ceiling effects in the outcome data assessed for each score were estimated. The data assessed with both patient-rating scores, the DASH and PRWE, showed substantial ceiling effects, whereas the data assessed with MMWS showed no ceiling effect. Researchers should be aware of a possible ceiling effect in the assessment of the outcome of the surgical treatment of distal radial fractures using patient-rating scores. It could also increase the likelihood of a type II error. Cite this article: Bone Joint J 2015;97-B:1651–6

To ascertain the optimum number, thickness and configuration of K-wires needed to prevent displacement of distal radial fractures. Synthetic and cadaver bones were used. A transverse osteotomy was performed 1. 5 cm proximal to the articular surface of the distal radius. Different numbers and configurations of 1. 1mm or 1. 6mm K-wires were used to hold the bone reduced. Dorsoradial and distraction forces were applied using a tensiometer. The endpoint was a displacement of 3mm at the osteotomy site. We demonstrated a statistically significant increase in the force required to displace the osteotomy site a) when using thicker wires and b) when using three crossed wires compared with two wires either crossed or parallel. When balancing ease of insertion with maximum stability, we would recommend two parallel 1. 6mm wires inserted through the radial styloid process, with 1 wire inserted from the dorsoulnar corner of the radius crossing at approximately 90 degrees. All wires should pass into the opposite cortex. This configuration resisted forces of over 300 Newtons and there was little benefit in using additional wires

Aims

The degree of displacement of a fracture of the distal radius is an important factor which can be assessed using simple radiographic measurements. Our aim was to investigate the reliability and reproducibility of these measurements and to determine if they should be used clinically.

Advancements in treating complications of operatively treated distal radius fractures. We will review tips and tricks to avoid complications associated with operative fixation of these complicated injuries. We will cover treatment of the distal radioulnar joint, associated distal ulna fracture, complications of malreduction and implant prominence. During this session, we will review the latest techniques for treating these complex distal radius fractures and how to avoid associated complications.

We reviewed 68 fractures of the distal radius in children, all treated by primary manipulation and plaster immobilisation. Complete displacement of the fracture and failure to achieve a perfect reduction were both associated with a significant increase in the chance of redisplacement. We recommend the use of percutaneous Kirschner wires to maintain a satisfactory position in all cases in which a perfect reduction cannot be achieved.

The aim of this study was to identify psychosocial factors associated with pain intensity and disability following distal radius fracture (DRF).

We prospectively followed up 216 adult patients with DRF for 9 months. Demographics, injury and treatment details and psychological measures (Hospital Anxiety and Depression Score (HADS), Pain Catastrophising Scale (PCS), Post Traumatic Stress Disorder Checklist – Civilian (PCL-C), Tampa Scale for Kinesiophobia (TSK), Illness Perception Questionnaire Brief (IPQB), General Self-efficacy Scale (GSES) and Recovery Locus of Control (RLOC)) were collected at enrolment. Multivariable linear regression was used to identify factors associated with DASH and Likert pain score.

Ten week DASH was associated with age (β-coefficient (β)= 0.3, p < 0.001), deprivation score (β=0.2, p = 0.014), nerve injury (β=0.1, p = 0.014), HADS depression (β=0.2, p = 0.008), IPQB (β=0.2, p = 0.001) and RLOC (β= −0.1, p = 0.031). Nine month DASH was associated with age (β=0.1, p = 0.04), deprivation score (β=0.4, p = 0.014), number of medical comorbidities (β=0.1, p = 0.034), radial shortening (β=0.1, p = 0.035), HADS depression (β=0.2, p = 0.015) and RLOC (β= −0.1, p = 0.027). Ten week pain score was associated with deprivation score (β=0.1, p = 0.049) and IPQB (β=0.3, p < 0.001). Pain score at 9 months was associated with number of medical comorbidities (β=0.1, p = 0.047).

Psychosocial factors are more strongly associated with pain and disability than injury or treatment characteristics after DRF. Identifying and treating these factors could enhance recovery.

Fractures of the distal forearm are widely regarded as the result of “fragility”. We have examined the extent to which patients with Colles’ fractures have osteopenia. We measured the bone mineral density (BMD) in the contralateral radius of 235 women presenting with Colles’ fractures over a period of two years. While women of all ages had low values for ultra-distal BMD, the values, in age-matched terms, were particularly low among premenopausal women aged less than 45 years. This result was not due to the presence of women with an early menopause. This large survey confirms and extends the findings from earlier small studies. We consider that it is particularly important to investigate young patients with fractures of the distal forearm to identify those with osteoporosis, to seek an underlying cause and to consider treatment.

Long term outcomes of distal radius fractures have rarely been studied prospectively and do not traditionally extend past 1–2 years following treatment. The purpose of this study was to describe the long term patient-rated pain and disability of patients after a distal radius fracture and to also determine the differences in patient reported pain and disability after one year following injury and at the long term follow-up.

Patients who had previously participated in a prospective study, where baseline and standardised one year follow-up were performed following a distal radius fracture were contact to participate in this long term follow-up (LTFU) study. Eligible cases that consented agreed to evaluation which included being sent a package in the mail contain a letter of information and questionnaire. Baseline demographic data including age and sex, as well as date of fracture, mechanism of fall and attending physician information was obtained for all participating subjects. Patient rated pain and disability was measured at baseline, one year and at long-term follow-up using the Patient Rated Wrist Evaluation (PRWE). Patients were categorised as having had a worse outcome (compared to one year follow-up PRWE scores) if their LTFU PRWE score increased by 5 points, having no change in status (if their score changed by four or less points) or improved if their LTFU PRWE score decreased by 5 or more points.

Sixty-five patients (17 male, 48 female) with an average age of 57 years at the time of injury and 67 years at follow-up were included in the study. The mean length of follow-up was 10.7 (± 5.8) years (range: 3–19 years). Overall, 85% of patients reported having no change or had less patient-reported pain and disability (PRWE) at their long-term follow-up compared to their one year PRWE scores. As well, one year PRWE scores were found to be predictive (20.2%) of the variability in long term PRWE score (p=0.001).

This study provided data on a cohort of prospectively followed patients with a distal radius fracture, approximately 10 years after injury. This data may be useful to clinicians and therapists who are interested in determining the long term effects of this frequently occurring upper extremity fracture. The results of this study indicate that after 10 years following a distal radius fracture, 85% of patients will have good outcomes. The results of this study also indicate that majority of cases, if patients have a low amount of pain and disability at one year, then these outcomes will also be true approximately 10 years later.

We conducted a retrospective analysis of 94 children with fractures of the distal third of the radius, with or without ulnar fractures, treated by primary closed reduction and plaster. The overall failure rate of 29% was due mainly to irreducibility, inability to maintain reduction and eventual limitation of forearm rotation. Age, sex and severity of angulation were not significant, but the direction of angulation and the degree of translation at either the radial or the ulnar fracture sites were significant risk factors. Translation of the radius was the single most reliable predictor of outcome (83% correct). The risk of failure in fractures with translation of the radius of more than half the diameter of the bone was 60%, compared with 8% for fractures with less translation.

The aims of this study were to assess the efficacy of a newly designed radiological technique (the radial groove view) for the detection of protrusion of screws in the groove for the extensor pollicis longus tendon (EPL) during plating of distal radial fractures. We also aimed to determine the optimum position of the forearm to obtain this view. We initially analysed the anatomy of the EPL groove by performing three-dimensional CT on 51 normal forearms. The mean horizontal angle of the groove was 17.8° (14° to 23°). We found that the ideal position of the fluoroscopic beam to obtain this view was 20° in the horizontal plane and 5° in the sagittal plane.

We then intra-operatively assessed the use of the radial groove view for detecting protrusion of screws in the EPL groove in 93 fractures that were treated by volar plating. A total of 13 protruding screws were detected. They were changed to shorter screws and these patients underwent CT scans of the wrist immediately post-operatively. There remained one screw that was protruding. These findings suggest that the use of the radial groove view intra-operatively is a good method of assessing the possible protrusion of screws into the groove of EPL when plating a fracture of the distal radius.

The use of volar locking compression plates for the treatment of fractures of the distal radius is becoming increasingly popular because of the stable biomechanical construct, less soft-tissue disturbance and early mobilisation of the wrist. A few studies have reported complications such as rupture of flexor tendons. We describe three cases of rupture of extensor tendons after the use of volar locking compression plates. We recommend extreme care when drilling and placing the distal radial screws to prevent damaging the extensor tendons.

This study compares the cost-effectiveness of treating dorsally displaced distal radial fractures with a volar locking plate and percutaneous fixation. It was performed from the perspective of the National Health Service (NHS) using data from a single-centre randomised controlled trial. In total 130 patients (18 to 73 years of age) with a dorsally displaced distal radial fracture were randomised to treatment with either a volar locking plate (n = 66) or percutaneous fixation (n = 64). The methodology was according to National Institute for Health and Care Excellence guidance for technology appraisals. . There were no significant differences in quality of life scores between groups at any time point in the study. Both groups returned to baseline one year post-operatively. . NHS costs for the plate group were significantly higher (p < 0.001, 95% confidence interval 497 to 930). For an additional £713, fixation with a volar locking plate offered 0.0178 additional quality-adjusted life years in the year after surgery. The incremental cost-effectiveness ratio (ICER) for plate fixation relative to percutaneous fixation at list price was £40 068. When adjusting the prices of the implants for a 20% hospital discount, the ICER was £31 898. Patients who underwent plate fixation did not return to work earlier. We found no evidence to support the cost-effectiveness, from the perspective of the NHS, of fixation using a volar locking plate over percutaneous fixation for the operative treatment of a dorsally displaced radial fracture.

This multicentre prospective clinical trial aimed to determine whether early administration of alendronate (ALN) delays fracture healing after surgical treatment of fractures of the distal radius. The study population comprised 80 patients (four men and 76 women) with a mean age of 70 years (52 to 86) with acute fragility fractures of the distal radius requiring open reduction and internal fixation with a volar locking plate and screws. Two groups of 40 patients each were randomly allocated either to receive once weekly oral ALN administration (35 mg) within a few days after surgery and continued for six months, or oral ALN administration delayed until four months after surgery. Postero-anterior and lateral radiographs of the affected wrist were taken monthly for six months after surgery. No differences between groups was observed with regard to gender (p = 1.0), age (p = 0.916), fracture classification (p = 0.274) or bone mineral density measured at the spine (p = 0.714). The radiographs were assessed by three independent assessors. There were no significant differences in the mean time to complete cortical bridging observed between the ALN group (3.5 months (se 0.16)) and the no-ALN group (3.1 months (se 0.15)) (p = 0.068). All the fractures healed in the both groups by the last follow-up. Improvement of the Quick-Disabilities of the Arm, Shoulder and Hand (QuickDASH) score, grip strength, wrist range of movement, and tenderness over the fracture site did not differ between the groups over the six-month period. Based on our results, early administration of ALN after surgery for distal radius fracture did not appear to delay fracture healing times either radiologically or clinically.

This article is a systematic review of the published literature about the biomechanics, functional outcome and complications of intramedullary nailing of fractures of the distal radius.

We searched the Medline and EMBASE databases and included all studies which reported the outcome of intramedullary (IM) nailing of fractures of the distal radius. Data about functional outcome, range of movement (ROM), strength and complications, were extracted. The studies included were appraised independently by both authors using a validated quality assessment scale for non-controlled studies and the CONSORT statement for randomised controlled trials (RCTs).

The search strategy revealed 785 studies, of which 16 were included for full paper review. These included three biomechanical studies, eight case series and five randomised controlled trials (RCTs).

The biomechanical studies concluded that IM nails were at least as strong as locking plates. The clinical studies reported that IM nailing gave a comparable ROM, functional outcome and grip strength to other fixation techniques.

However, the mean complication rate of intramedullary nailing was 17.6% (0% to 50%). This is higher than the rates reported in contemporary studies for volar plating. It raises concerns about the role of intramedullary nailing, particularly when comparative studies have failed to show that it has any major advantage over other techniques. Further adequately powered RCTs comparing the technique to both volar plating and percutaneous wire fixation are needed.

Aims. It is not clear which type of casting provides the best initial treatment in adults with a distal radial fracture. Given that between 32% and 64% of adequately reduced fractures redisplace during immobilization in a cast, preventing redisplacement and a disabling malunion or secondary surgery is an aim of treatment. In this study, we investigated whether circumferential casting leads to fewer fracture redisplacements and better one-year outcomes compared to plaster splinting. Methods. In a pragmatic, open-label, multicentre, two-period cluster-randomized superiority trial, we compared these two types of casting. Recruitment took place in ten hospitals. Eligible patients aged ≥ 18 years with a displaced distal radial fracture, which was acceptably aligned after closed reduction, were included. The primary outcome measure was the rate of redisplacement within five weeks of immobilization. Secondary outcomes were the rate of complaints relating to the cast, clinical outcomes at three months, patient-reported outcome measures (PROMs) (using the numerical rating scale (NRS), the abbreviated version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH), and Patient-Rated Wrist/Hand Evaluation (PRWHE) scores), and adverse events such as the development of compartment syndrome during one year of follow-up. We used multivariable mixed-effects logistic regression for the analysis of the primary outcome measure. Results. The study included 420 patients. There was no significant difference between the rate of redisplacement of the fracture between the groups: 47% (n = 88) for those treated with a plaster splint and 49% (n = 90) for those treated with a circumferential cast (odds ratio 1.05 (95% confidence interval (CI) 0.65 to 1.70); p = 0.854). Patients treated in a plaster splint reported significantly more pain than those treated with a circumferential cast, during the first week of treatment (estimated mean NRS 4.7 (95% CI 4.3 to 5.1) vs 4.1 (95% CI 3.7 to 4.4); p = 0.014). The rate of complaints relating to the cast, clinical outcomes and PROMs did not differ significantly between the groups (p > 0.05). Compartment syndrome did not occur. Conclusion. Circumferential casting did not result in a significantly different rate of redisplacement of the fracture compared with the use of a plaster splint. There were comparable outcomes in both groups.

The relationship between advancing patient age, decreasing bone mineral density and increasing distal radial fracture incidence is well established. Biomechanical and clinical work has shown that the radiographic severity of distal radial fractures is greater in patients with poor bone quality. Between 1991 and 2007, the number of elderly Scots (aged 75 years or more) increased by 18%, and population projections predict a further 82% increase by 2035. This study was conducted to investigate the effect of recent changes in the demographics of our population on the pattern and radiographic severity of distal radial fractures encountered at our institution. The epidemiology of two distinct series of patients (1991–93; 2007–08) suffering distal radial fractures was compared. The patient and radiographic fracture characteristics known to be predictive of fracture instability and severity were compared using the MacKenney formulae, and a subgroup analysis of distal radial fragility fractures was performed. The life expectancy of our catchment population has improved since 1991, and we have encountered a larger number of distal radial fractures occurring in older, more active and functionally independent patients. We identified an increase in the proportion of AO type B fractures, particularly in the oldest patient groups. The radiographic severity of distal radial fractures, especially low energy metaphyseal injuries, has increased. If the current trend in population demographics continues, it seems likely that orthopaedic surgeons will encounter an increasing number of severe distal radial fractures deemed unsuitable for treatment by closed methods

Displaced distal radial fractures in adults are commonplace. Acknowledging that satisfactory radiographic parameters typically will beget satisfactory functional outcomes, management of these fractures includes a reduction followed by either cast/splint immobilisation or internal fixation. While we can generally rely on internal fixation to maintain the reduction the same is not true of cast immobilisation. There are, however, limited data defining the fate of a fracture reduction in those treated in a cast and up to the time of radial union. Traditional practice is to recommend six weeks of immobilisation. Our goal was to detail the radiographic patterns of change in the radiographic parameters of radial inclination (RI), ulnar variance (UV) and radial tilt (RT) over the first twelve weeks in women fifty years old and older who had sustained a displaced distal radial fracture. We examined serial standard PA and lateral distal radius radiographs of 647 women treated by closed reduction and casting for a displaced fracture of the distal radius. Measurements of RI, UV and RT from standardised radiographs were made immediately post-reduction as well as, as often as possible/feasible, at 1,2,3,6,9 and 12 weeks post fracture. All measurements were made by the senior author (accuracy range: 2 degrees for RI, 1 mm for UV and 4 degrees for RT, in 75% of cases). The primary outcome measure was the change in fracture position over time. Secondary outcomes included changes related to age group; known bone density; the relation to associated ulnar fractures; and independence of the variables of RI, UV and RT. The mean immediate post-reduction values for RI, UV and RT were 21 degrees, 1.5 mm, and −6 degrees, respectively. These all changed in the first six weeks, and did not in the second six week period. The mean change in RI was 3 degrees, 60% of the change occurring in the first week post-reduction; only 0.3 degrees of change was noted beyond three weeks. The mean UV increased by 2.2 mm over the first 6 weeks, 23% in the first week post reduction. The mean RT change of 7.7 degrees was also gradual over the first 6 weeks, with no significant change afterwards. The RI changes identified were not influenced by patient age, while UV and RT changes were greater in older groups. Those fractures of the distal radius associated with a distal ulnar shaft or neck fracture did not lose radial inclination over the study period. We have defined patterns of loss of reduction that commonly occur post reduction of a displaced distal radius fracture in women fifty years and older. Such patterns ought to guide our closed management of distal radial fractures, whether by altering the duration or method of casting. Women fifty years old and older, and physicians alike, must be advised that conventional casting post distal radial fracture reduction unreliably maintains fracture reduction

The aim of this study was to investigate surgeons’ reported change of treatment preference in response to the results and conclusion from a randomized controlled trial (RCT) and to study patterns of change between subspecialties and nationalities. Two questionnaires were developed through the Delphi process for this cross-sectional survey of surgical preference. The first questionnaire was sent out before the publication of a RCT and the second questionnaire was sent out after publication. The RCT investigated repair or non-repair of the pronator quadratus (PQ) muscle during volar locked plating of distal radial fractures (DRFs). Overall, 380 orthopaedic surgeons were invited to participate in the first questionnaire, of whom 115 replied. One hundred surgeons were invited to participate in the second questionnaire. The primary outcome was the proportion of surgeons for whom a treatment change was warranted, who then reported a change of treatment preference following the RCT. Secondary outcomes included the reasons for repair or non-repair, reasons for and against following the RCT results, and difference of preferred treatment of the PQ muscle between surgeons of different nationalities, qualifications, years of training, and number of procedures performed per year. Of the 100 surgeons invited for the second questionnaire, 74 replied. For the primary outcome, 6 of 32 surgeons (19%), who usually repaired the PQ muscle and therefore a change of treatment preference was warranted, reported a change of treatment preference based on the RCT publication. Of the secondary outcomes, restoring anatomy was the most common response for repairing the PQ muscle. The majority of the orthopaedic surgeons, where a change of treatment preference was warranted based on the results and conclusion of a RCT, did not report willingness to change their treatment preference

Despite the variety of implants or techniques that exist to treat displaced distal radial fractures, the majority fail to provide sufficient stability to permit early functional recovery. However, locking plates have the advantage over other implants in that locking screws add considerably to the overall stability. The aim of this study was to assess the functional outcome of patients with displaced distal radial fractures treated with a volar distal radial locking plate (Synthes). During a two year period, details of 98 patients admitted to our unit with inherently unstable dorsally displaced distal radial fractures treated with volar locking plates were collected prospectively. For the purpose of this analysis, only those patients (55) with unilateral fracture, able to attend the study clinic at 6 months post-injury were considered. Patients were immobilised in wool and crepe for a 2 week period. The group consisted of 15 males and 40 females with an average age of 54 (28 to 83). At 6 months, patients' perceived functional recovery averaged 80%. Objective assessment was considered in relation to the uninjured side: grip strength 73%; pinch strength 83%; palmarflexion 77%, dorsiflexion 80%; radial deviation 74%; ulnar deviation 74%; pronation 93%, and supination 92%. Seven patients complained of symptoms relating to prominent metalwork. Good/excellent early subjective and objective functional recovery was made following open reduction and internal fixation using volar locking plates of dorsally displaced distal radial fractures. We suggest that objective assessment of grip strength and dorsiflexion can be used as a measure of patient perception of function

Aims. Distal radial fractures are the most common fracture sustained by the adult population. Most can be treated using cast immobilization without the need for surgery. The aim of this study was to assess the feasibility of a definitive trial comparing the commonly used fibreglass cast immobilization with an alternative product called Woodcast. Woodcast is a biodegradable casting material with theoretical benefits in terms of patient comfort as well as benefits to the environment. Methods. This was a multicentre, two-arm, open-label, parallel-group randomized controlled feasibility trial. Patients with a fracture of the distal radius aged 16 years and over were recruited from four centres in the UK and randomized (1:1) to receive a Woodcast or fibreglass cast. Data were collected on participant recruitment and retention, clinical efficacy, safety, and patient acceptability. Results. Over an eight-month period, 883 patients were screened, 271 were found to be eligible, and 120 were randomized. Patient-reported outcome measures were available for 116 (97%) of participants at five weeks and 99 (83%) at three months. Clinical outcomes and patient acceptability were similar between the two interventions and no serious adverse events were reported in either intervention arm. Conclusion. Both interventions were deemed efficacious and safe in the cohort studied. This study showed that a definitive study comparing Woodcast and fibreglass was feasible in terms of patient recruitment and retention. Cite this article: Bone Joint J 2020;102-B(1):48–54

We sought to quantify agreement by different assessors of the AO classification for distal fractures of the radius. Thirty radiographs of acute distal radial fractures were evaluated by 36 assessors of varying clinical experience. Our findings suggest that AO ‘type’ and the presence or absence of articular displacement are measured with high consistency when classification of distal radial fractures is undertaken by experienced observers. Assessors at all experience levels had difficulty agreeing on AO ‘group’ and especially AO ‘subgroup’. To categorise distal radial fractures according to joint displacement and AO type is simple and reproducible. Our study examined only whether distal radial fractures could be consistently classified according to the AO system. Validation of the classification as a predictor of outcome will require a prospective clinical study

Aim: To investigate factors that influence outcomes one year after distal radial fractures To investigate how deformity (radiologically), functional outcome and patient satisfaction affect one another. Background: Identifying the factors that influence outcome in DRF is important in anticipating and treating patients with potentially correctable factors that may affect recovery. Previous studies have looked at different sub-sets of the DRF group most often with patient reported outcomes. We have reviewed a large consecutive group of DRF looking at which factors influenced the outcomes. Methods: Data on 640 distal radial fractures was prospectively recorded over a 24 month period. The database was reviewed and validated. Mechanism of injury, hand dominance and occupation were noted. Initial, post reduction, one week, 6 week and one year x-rays were taken. The volar and dorsal shortening, tilt and angulation were recorded. Any operative intervention or complication was noted. At one year follow up functional testing was performed including range of movement. This tested for grip strength, multiple postional strengths and a functional score looking at activities of daily living. Results: Prediction of functional outcome was significantly associated with age, volar communition, dorsal angulation and pain. The grip strength after a distal radial fracture is significantly stronger in dominant side fractures compared with non dominant, in younger patients and those without dorsal communition. We also showed that fractures that are most likely to malunite show a significantly poorer functional outcome and weaker grip strength. Conclusion: This study identifies factors that predict the functional outcome in Distal Radial fractures. Although many assumptions are made that certain fractures lead to poorer results this has rarely been shown in such a large, diverse group of DRFs. In an age where patients and practitioners strive to ever increasing levels of knowledge this study allows us to counsel patients in their likely functional outcomes more accurately

In recent years volar locking plates (VLP) have revolutionised the treatment of more complex distal radial fractures, but doubt still exists as to whether this is an operation for all suitably qualified orthopaedic surgeons, in particular experienced trainees, or remains the domain of consultants or better still upper limb surgeons. Aims: To assess changes in a Level 1 Trauma Unit’s practice over a 5 year period and to compare the clinical outcomes of patients operated upon by experienced orthopaedic trainees and consultant surgeons. Methods: Two prospective cohort studies were undertaken using (a) the Synthes VLP (January 2003–January 2005), and (b) the Periloc (Smith & Nephew) VLP (January 2007–February 2008). All patients were assessed at 6 months following surgery for range of movement, grip and pinch strength, and subjective levels of pain and function using Visual Numerical Scales. 65 and 36 patients were available for 6 month review in the Synthes and Periloc groups respectively. Operations undertaken by, or assisted directly by, the consultant were considered to be ‘consultant’ procedures, with all others being undertaken by trainees. Results: No significant patient demographical differences, or differences in fracture type were identified for the two cohorts. Clinical outcomes for the two cohorts were likewise similar at 6 months although there was a suggestion that pain, pinch and grip strength were marginally better in the Periloc group although this was not statistically significant. In the Synthes VLP cohort, 32 operations were undertaken by consultants and 33 by trainees, compared with 9 and 27 operations being undertaken by consultants and trainees respectively in the Periloc group. Although there was a tendency for the more difficult fractures to be operated upon by consultants, especially in the earlier cohort, trainees were left to deal with many of the more complex injuries in the Periloc cohort. The incidence of minor complications requiring further surgery (all relating to prominent metalwork) was also low in both groups (7 in the first group and 2 in the second group) with all but one of the index operations having been performed by a trainee. Discussion: Despite the complexity of many distal radial fractures, VLP treatment of distal radial fractures has become a common place procedure that, in our unit, are frequently left to experienced trainees to operate upon without supervision. Our prospectively cohort studies clearly show that, over time, experienced trainees obtain clinical results that are similar to their consultant colleagues with respect to clinical outcome and incidence of complications. Conclusions: As our unit’s experience of treating patients with distal radial fractures with VLPs has grown, experienced trainees appear to obtain clinical results that are similar to consultants

Aims. Assessment of bone mineral density (BMD) with dual-energy X-ray absorptiometry (DXA) is a well-established clinical technique, but it is not available in the acute trauma setting. Thus, it cannot provide a preoperative estimation of BMD to help guide the technique of fracture fixation. Alternative methods that have been suggested for assessing BMD include: 1) cortical measures, such as cortical ratios and combined cortical scores; and 2) aluminium grading systems from preoperative digital radiographs. However, limited research has been performed in this area to validate the different methods. The aim of this study was to investigate the evaluation of BMD from digital radiographs by comparing various methods against DXA scanning. Methods. A total of 54 patients with distal radial fractures were included in the study. Each underwent posteroanterior (PA) and lateral radiographs of the injured wrist with an aluminium step wedge. Overall 27 patients underwent routine DXA scanning of the hip and lumbar spine, with 13 undergoing additional DXA scanning of the uninjured forearm. Analysis of radiographs was performed on ImageJ and Matlab with calculations of cortical measures, cortical indices, combined cortical scores, and aluminium equivalent grading. Results. Cortical measures showed varying correlations with the forearm DXA results (range: Pearson correlation coefficient (r) = 0.343 (p = 0.251) to r = 0.521 (p = 0.068)), with none showing statistically significant correlations. Aluminium equivalent grading showed statistically significant correlations with the forearm DXA of the corresponding region of interest (p < 0.017). Conclusion. Cortical measures, cortical indices, and combined cortical scores did not show a statistically significant correlation to forearm DXA measures. Aluminium-equivalent is an easily applicable method for estimation of BMD from digital radiographs in the preoperative setting. Cite this article: Bone Joint Res 2021;10(12):830–839

The purpose of this study was to evaluate the risk of late displacement after the treatment of distal radial fractures with a locking volar plate, and to investigate the clinical and radiological factors that might correlate with re-displacement. From March 2007 to October 2009, 120 of an original cohort of 132 female patients with unstable fractures of the distal radius were treated with a volar locking plate, and were studied over a follow-up period of six months. In the immediate post-operative and final follow-up radiographs, late displacement was evaluated as judged by ulnar variance, radial inclination, and dorsal angulation. We also analysed the correlation of a variety of clinical and radiological factors with re-displacement. Ulnar variance was significantly overcorrected (p < 0.001) while radial inclination and dorsal angulation were undercorrected when compared statistically (p <  0.001) with the unaffected side in the immediate post-operative stage. During follow-up, radial shortening and dorsal angulation progressed statistically, but none had a value beyond the acceptable range. Bone mineral density measured at the proximal femur and the position of the screws in the subchondral region, correlated with slight progressive radial shortening, which was not clinically relevant. Volar locking plating of distal radial fractures is a reliable form of treatment without substantial late displacement. Cite this article: Bone Joint J 2013;95-B:396–400

We studied prospectively the regional inflammatory response to a unilateral distal radial fracture in 114 patients at eight to nine weeks after injury and again at one year. Our aim was to identify patients at risk for a delayed recovery and particularly those likely to develop complex regional pain syndrome. In order to quantify clinically the inflammatory response, a regional inflammatory score was developed. In addition, blood samples were collected from the antecubital veins of both arms for comparative biochemical and blood-gas analysis. The severity of the inflammatory response was related to the type of treatment (Kruskal-Wallis test, p = 0.002). A highly significantly-positive correlation was found between the regional inflammatory score and the length of time to full recovery (r. 2. = 0.92, p = 0.01, linear regession). A regional inflammatory score of 5 points with a sensitivity of 100% but a specificity of only 16% also identified patients at risk of complex regional pain syndrome. None of the biochemical parameters studied correlated with regional inflammatory score or predicted the development of complex regional pain syndrome. Our study suggests that patients with a distal radial fracture and a regional inflammatory score of 5 points or more at eight to nine weeks after injury should be considered for specific anti-inflammatory treatment

Introduction. Fractures of the distal radius are one of the most common extremity fractures encountered in A&E departments and general adult fracture clinics. Over the last 10 years the rate of operation for distal radial fractures has been steadily increasing. Staff within our unit felt that formal teaching, particularly of new medical staff, with regards to fracture reduction and appropriate cast application could result in a reduction in operation rates. Methods. Retrospective data was extracted from FORD (Fracture Outcome and Research Database). Data included: the number of fractures in a 6 month period, number of fractures undergoing ORIF in that period, fracture configuration, patient demographics, and mechanism of injury. All patients undergoing ORIF had their radiographs assessed by 2 separate reviewers. Information regarding adequate fracture reduction, adequate cast application (using Gap Index calculation), and appropriate plaster cast moulding was recorded. Formal teaching was then given to the next group of medical staff rotating through the unit, and the same data was collected prospectively for that 6 month period. Exclusion criteria included bilateral injuries, and polytrauma patients. Results. A total of 1712 distal radial fractures were treated in our unit over the 12 month period, with 71 undergoing ORIF in the first 6 months and 37 in the second 6 months. Our study found that formal teaching and education of medical staff significantly reduced the operation rate for distal radial fractures in our unit. This effect was most significant for extra-articular, dorsally angulated fractures of the distal radius. Conclusion. In today's busy hospital environment it is sometimes all too easy to overlook the training of junior medical staff, our study proves that just 1 hour of basic training at the beginning of an attachment can have significant benefits to both the unit and, more importantly, the patients

Historically the management of distal radial fracture has been often inadequate. It can be difficult to internally fix complex distal radial fractures with conventional plates. The fracture often collapses with metalwork failure. Literature suggests that malunion may lead to painful wrist with loss of function. In recent years fixed angle locking plate has been advocated for treatment of complex distal radius fracture. Our aim was to assess to assess the effectiveness of the volar locking plate (DePuy) in maintaining fracture reduction in distal radial fractures. Radiographs of 170 distal radius fractures treated by the DVR plate were analysed. Fractures were classified according to the Melone and AO classifications. The post injury, intra-operative, 6 weeks postoperative and final postoperative radiographs were reviewed to obtain measurements for radial height, radial slope and volar inclination. The measurements were correlated with fracture pattern, locking screw length, presence or absence of radial styloid screw and plate placement in relation to the wrist joint. The results were analysed statistically using Wilcoxon signed rank test. Radiologically there was minor loss of radial height, slope and volar inclination but this was not statistically significant. There was a statistically significant correlation between complexity of fracture and loss of radiological parameters. There was no statistically significant correlation between loss of radiological parameters and screw length, plate placement or presence or absence of radial styloid screw. The DVR volar locking plate appears to maintain a satisfactory reduction of the fracture except for some complex fractures with dorsal comminution in which case dorsoradial plates may be preferable

Aim: To assess the ability of volar locking plates to maintain fracture reduction when used to treat dorsally displaced extra and intra-articular distal radial fractures. Methods: This prospective study was conducted over a 12 month period. Consenting patients who had sustained a closed, dorsally displaced distal radial fracture, treated by open reduction and internal fixation using a volar distal radial locking plate, were included in the study. Radial inclination, volar tilt and ulnar variance were measured from radiographs taken at least 3 months after surgery and compared with radiographs of the uninjured side. Only two of the eight participating surgeons have a specialist interest in upper limb surgery. Results: Thirty-three patients were included in the study. There were 23 females and 10 males. The mean age was 49.5 years, range 26–82 years. According to the OTA classification there were 19 Type A, 1 Type B and 13 Type C fractures. The mean restoration of volar tilt was 1° of under-correction, median 1.1° under-correction with a range of 7.3° of under-correction to 3.7° of over-correction, when compared with the uninjured side. The mean restoration of radial inclination was 1.9° of under-correction, median 1.6° under-correction with a range of 10° of under-correction to 8.4° of over-correction. As a group the mean ulnar variance was 0mm with a range of 2mm of relative ulnar shortening to 3.5mm of ulnar prominence when compared with the uninjured side. Conclusion: In the hands of general trauma surgeons, the volar approach combined with the application of a suitable volar locking plate is a good treatment for restoring and maintaining the anatomy of dorsally displaced intra and extra-articular distal radial fractures

To assess the percentage of patients with an osteoporotic distal radial fracture who had any subsequent investigation or treatment for osteoporosis, and to compare this to the gold standard, all patients seen in a hospital fracture clinic with an osteoporotic fracture should be advised of the possibility of osteoporosis and their primary care team informed of the need for follow-up (Royal College of Physicians, National Osteoporosis Society and The Advisory Group on Osteoporosis). All patients over 50 years old who sustained a distal radial fracture and a subsequent fractured neck of femur after simple falls, over a 7-year period, were included. Evidence of any treatment for, or investigation of, osteoporosis between the initial radial fracture and subsequent neck of femur fracture was recorded. 74 patients met the above criteria. 7 male and 67 female, median age 83 (54 to 99). Eight percent of cases were on treatment for osteoporosis at time of first fracture. A further 8% had evidence of treatment for, or investigation of, osteoporosis commenced by time of their 2nd fracture. 84% of patients received no advice, investigation or treatment. As orthopaedic surgeons we have a duty to inform the primary care team of the need to follow-up patients with osteoporotic fractures. There is a significant cost benefit both to the patient and the health service. We aim to introduce a system whereby a letter is automatically sent to the GP informing them that their patient has been seen in fracture clinic with an osteoporotic distal radial fracture. The letter will also advise them of the current Royal College and Government guidelines on investigation and treatment of osteoporosis. We aim to repeat the audit cycle after a 5-year period with the new system in place

Purpose: This in-vitro study examined the effect of simulated Colles fractures on load transmitted to the distal ulna, using an in-line load cell. Our hypothesis was distal radial fracture malposition will increase distal radial ulnar joint (DRUJ) load relative to the native position of the radius. Method: Eight fresh frozen upper-extremities were mounted in a motion simulator which enabled active forearm rotation. An osteotomy was performed just proximal to the distal radioulnar joint, and a 3-degree of freedom modular appliance was implanted which simulated Colles type distal radial fracture deformities. This device allowed for accurate adjustment of dorsal angulation and translation (0, 10, 20 and 30 degrees dorsal angulation and 0, 5 and 10mm dorsal translation both isolated and in combination). A 6-DOF load cell was inserted in the distal ulna 1.5 cm proximal to the ulnar head to quantify DRUJ joint forces. Distal ulnar loading was measured following simulated distal radial deformities with both an intact and sectioned triangular fibrocartilage complex (TFCC). Results: The maximum resultant transverse distal ulnar load occurred during active forearm pronation and supination. Increasing magnitudes of dorsal angulation and translation of the distal radius increased loading in the distal ulna. For pronation with the ligaments intact, the transverse resultant load for the non-fracture, native positioning was significantly lower (p< 0.05) than the majority of malpositioned cases except for the translations only (not combined with angulation). However, all fracture orientations for supination had an increased effect on the resultant loading (p< 0.05) when ligaments were intact. Greater forces were measured in the distal ulna when the TFCC intact relative to TFCC sectioning. Sectioning the TFCC eliminated the effect of fracture malposition for both pronation and supination. The range of maximum transverse force for intact pronation and supination was between 118& #61617;34N and 130& #61617;39N, respectively. Similarly, for sectioned pronation and supination, the maximum transverse forces were and 93& #61617;40N and 89& #61617;24N, respectively. Conclusion: Malpositioning of distal radial fractures in dorsal translation and angulation was found to increase forces in the distal ulna, which may be an important source of residual pain following malunion of Colles fractures. Healing of the distal radius in an anatomic position resulted in the least forces. Sectioning the TFCC released the tethering effect of the radius on the ulna, decreasing DRUJ force. This is the first study of its kind to attempt to quantify the forces at the DRUJ as a result of Colles fractures, and these early findings provide important baseline information related to the biomechanics of the DRUJ

Aim: To demonstrate that a novel tricalcium phosphate bone cement (Biobon) could be effectively used to þll the dorsal metaphyseal defect after unstable distal radial fractures in the osteopenic wrist, and to conþrm with biomechanical studies that its mechanical properties were incompatible with its sole use. Methods: Compression and Biaxial ßexure testing was performed under both dry and wet conditions of physiological Saline and Ringers Lactate solutions at 37ûC. 9 female patients with a mean age of 65 years sustaining Frykman grade VIII fractures of the distal radius between 1999 and 2000 underwent open reduction and internal þxation with supplementation of the dorsal metaphyseal defect with Biobon. Results: Youngs Modulus (E) and the Ultimate compressive strength (UCS) for the two solutions were identical at 10 hours (406 MPa and 3.24 MPa respectively), reaching a maximum for Ringers Lactate solution. The Biaxial ßexure stress also reached a maximum value at 10 hours for Saline at 37û C (3.96 MPa). A signiþcant improvement of radiographic parameters were observed post-operatively (Mean volar tilt = + 1.1û; Mean radial length = 10.4mm: Mean radial inclination = 20.5û) and remained so at the time of assessment (Mean volar tilt = +2.5û; Mean radial length = 10.4 mm; Mean radial inclination = 21.8û).Conclusion: The use of a tri-calcium phosphate bone cement is an effective means of addressing the dorsal comminution sustained after unstable distal radial fractures. Its biomechanical properties precludes its sole use for the treatment of distal radial fractures

The December 2014 Trauma Roundup. 360 . looks at: infection and temporising external fixation; Vitamin C in distal radial fractures; DRAFFT: Cheap and cheerful Kirschner wires win out; femoral neck fractures not as stable as they might be; displaced sacral fractures give high morbidity and mortality; sanders and calcaneal fractures: a 20-year experience; bleeding and pelvic fractures; optimising timing for acetabular fractures; and tibial plateau fractures

Aims. Displaced distal radius fractures were investigated at a level 1 major trauma centre during the COVID-19 2020 lockdown due to the implementation of temporary changes in practice. The primary aim was to establish if follow-up at one week in place of the 72-hour British Orthopaedic Association Standards for Trauma & Orthopaedics (BOAST) guidance was safe following manipulation under anaesthetic. A parallel adaptation during lockdown was the non-expectation of Bier’s block. The secondary aim was to compare clinical outcomes with respect to block type. Methods. Overall, 90 patients were assessed in a cross-sectional cohort study using a mixed, retrospective-prospective approach. Consecutive sampling of 30 patients pre-lockdown (P1), 30 during lockdown (P2), and 30 during post-lockdown (P3) was applied. Type of block, operative status, follow-up, and complications were extracted. Primary endpoints were early complications (≤ one week). Secondary endpoints were later complications including malunion, delayed union or osteotomy. Results. In P1, 86.6% of patients were seen between days one to three, 26.7% in P2, and 56.7% in P3. There were no documented complications from days one to three. Operative rate was 35.5%, which did not vary significantly (p= 0.712). Primary endpoints occurred between day four to seven, and included one patient each period treated for plaster cast pain. Secondary endpoints in P1 included delayed union (one patient). During P2, this included malunion (one patient), a pressure sore (one patient) and ulnar cutaneous nerve symptoms (two patients). In P3, malunion was identified in one patient. Mean follow-up was six months (4 to 9) with union rate 96%. Change in block practice varied significantly (p =＜0.05). The risk ratio of complications using regional block (Bier’s) over haematoma block was 0.65. Conclusion. Follow-up adaptations during lockdown did not adversely affect patient outcomes. Regional anaesthesia is gold standard for manipulation of displaced distal radial fractures. Cite this article: Bone Jt Open 2021;2(5):338–343

The December 2012 Trauma Roundup. 360. looks at: whether tranexamic acid stops bleeding in trauma across the board; antibiotic beads and VAC; whether anaesthetic determines the outcome in surgery for distal radial fractures; high complications in surgery on bisphosphonate-hardened bone; better outcomes but more dislocations in femoral neck fractures; the mythical hip fracture; plate augmentation in nonunion surgery; and SIGN intramedullary nailing and infections

Sixteen observers measured eight anatomic parameters on digitalised images of six acute distal radial fractures using the Patient Archiving Communication System (PACS) software and repeated the measurements two weeks later. Inter and intra observer variability for each parameter was calculated using intraclass correlation coefficients (ICC) and tolerance limits (TL). Highest inter-observer agreement was demonstrated in dorsal tilt (ICC 0.858; TL ± 14.2°) with poor agreement on the size of the gap and step. When compared with the results of a similar study published 10 years ago looking at observer variability in x-ray measurement of healed distal radial fractures, the reliability of computerized measurements is not significantly different to those achieved by manual techniques (dorsal tilt inter-observer TL on PACS ± 16° compared with TL ± 15° using ruler and protractor). These results suggest the current guidelines in the literature for acceptable radiological reduction limits based on < 10° change in palmar tilt, < 2mm radial shortening, < 5° change in radial angle and < 1–2mm articular step for acute distal radius fractures cannot be reliably measured

The ITS volar radial plate (Implant Technology Systems, Graz/Austria) is a fixation device that allows for the distal locking screws to be fixed at variable angles (70°-110°). This occurs by the different material properties, with the screws (titanium alloy) cutting a thread through the plate holes (titanium). We present our experience with the ITS plate. We retrospectively studied 26 patients who underwent ITS plate fixation for unstable multifragmentary distal radial fractures (AO types A3, B2, B3, C2, C3). The surgery was performed either by a consultant orthopaedic hand surgeon or senior registrar. A volar approach was used every time and 10 cases required synthetic bone grafting. Post-operatively they were immobilised for an average of 2.5 weeks. The 26 patients had a mean age of 58 and the dominant side was affected in 46% of cases. 5 cases were open fractures and 10 cases followed failed manipulation under general anaesthesia. The average interval between injury and surgery was 7 days. Union was achieved in all cases. No implant infections, failure or tendon rupture/irritation occurred. There were two fractures which loss reduction, of which one required revision surgery. There was one case of CRPS. The six month average DASH score was 27.5. We consider the ITS plate a technically easy plate to use and a reliable implant at early follow-up. We value the versatility of its variable angle screw fixation ability for complex intra-articular distal radial fractures

We identified 11 women with a mean age of 74 years (65 to 81) who sustained comminuted distal radial and ulnar fractures and were treated by volar plating and slight shortening of the radius combined with a primary Sauvé-Kapandji procedure. At a mean of 46 months (16 to 58), union of distal radial fractures and arthrodesis of the distal radioulnar joint was seen in all patients. The mean shortening of the radius was 12 mm (5 to 18) compared to the contralateral side. Flexion and extension of the wrist was a mean of 54° and 50°, respectively, and the mean pronation and supination of the forearm was 82° and 86°, respectively. The final mean disabilities of the arm, shoulder and hand score was 26 points. According to the Green and O’Brien rating system, eight patients had an excellent, two a good and one a fair result. The good clinical and radiological results, and the minor complications without the need for further operations related to late ulnar-sided wrist pain, justify this procedure in the elderly patient

Aims: The aim of this study was to þnd out if undisplaced displaced distal radial fractures require plaster immobilisation. Methods: In this prospective study, undisplaced distal radial fractures were divided into two groups; plaster immobilisation was used for one group while removable volar splint was used for the other group. Follow up was at six weeks, three months and six months. Patients were assessed by clinical examination, grip strength, radiological assessment, EQ-5D and a Short Form 12 questionnaire. Results: At 3 months, no difference was found between the two groups in clinical evaluation, radiological assessment, the functional outcome, grip strength, and visual analogue score for pain. Conclusions: We conclude that undisplaced distal radius fractures can probably be treated with out a plaster cast and put straight into wrist orthosis

We performed a prospective audit to assess radiological and clinical sequelae of using injectable calcium sulphate in the management of distal radial fractures. All patients in a 4-month period who were treated with injectable calcium sulphate for distal radial fracture were included in the audit. Initial data was collected on demographics; AO classification and degree of deformity; method of fixation and surgical complications. Follow up consisted of clinical and radiological assessment of fracture healing at standard fracture clinic intervals with a final assessment of subjective functional recovery. 16 patients were included in the audit, all of whom were followed up for a minimum of 8 weeks. We observed a low incidence of secondary displacement, and did not observe the problem of increased pain and erythema that has been observed with other bone graft substitutes. We conclude that injectable calcium sulphate is a useful adjunct to conventional management of these fractures that is safe, helps maintain fracture reduction and is not associated with product specific complications

The April 2012 Trauma Roundup. 360 . looks at fibula-pro-tibia plating, galeazzi fractures, distal radial fractures in the over 65s, transverse sacral fractures, acute dislocation of the knee, posterior malleolar fractures, immobilising the broken scaphoid, the terrible triad, lower limb amputation after trauma, and whiplash injuries

The use of percutaneous Kirschner wires [K-wires] and plaster is a popular method of treatment for displaced distal radius fracture. However, multi-database electronic literature review reveals unsurprisingly different views regarding their use. From August 2002 till June 2004, 280 distal radial fractures were admitted to our orthopaedic department. They were recorded prospectively in the departmental trauma admissions database. We studied the 87 cases treated with the K-wires and plaster technique. They were classified according to the AO classification system. The mean patient age was 53 [5-88] years. The mean delay before surgery was 7 [0-24] days. We studied the complications reported by the attending orthopaedic surgical team. 48 out of 87 patients [55.1%] were reported to have complications. We analysed the displacement and the pin tract infection, as they were the main reported complications. 28 out of 87 patients [32%] had displacement [9 had further surgery to correct the displacement, 19 did not have any further surgery as the displacement was accepted]. 11 out of 87 patients [12.6%] had pin tract infection [7 needed early removals of the K-wires and systematic treatment]. Further analysis showed no statistically significant relation between the complications rate and the age of the patients, the delay before surgery or the type of the fractures. We demonstrate a considerable high displacement and infection rate with the use of K-wires and plaster technique for fixation of distal fracture irrespective of the age of the patients, the delay before surgery or the fracture classification. There are other methods for fixation of the distal radial fracture with proven less morbidity which should be considered

Aim of the study: to assess the early complication rate following k-wiring of distal radial fractures and their final clinical outcome. Materials & methods: a prospective study. 48 Patients with 50 distal radial fractures (26 male,22 female) with mean age 34 years(range 4–88) were treated by closed k-wiring during the period jan 2005-june 2005. They were assessed in terms of early complications following mua and k-wiring and their final clinical outcome. Results: 12 patients(24%)had discharge, pin tract granulation, loosening out of which 4 required antibiotics. Out of 12 only 2(4%) had positive swab culture requiring i.V. Antibiotics. 3(6%)Had symptoms suggesting superficial radial nerve damage of which 2 recovered completely after pin removal. One had residual symptom which got better before planned exploration. 9 Patients (18%)had stiffness of which only 3(6%)had residual stiffness at the end of 6 months. Crps was noted in 1 patient(2%)who recovered after good physio. There wer nocases of deep infection, osteomyelitis, tendon rupture, pin migration or significant loss of position. Conclusion: our data suggests that though early complication rate of k-wiring is alarming, it doesnot affect the final clinical outcome of fracture management and this complication can be avoided by proper technique and care. There is no rationale in giving antibiotic coverage for all the pintract discharges unless swab positive

In 2000 our emergency department implemented a new management for the treatment of isolated, apex volar distal radial fractures involving immobilisation with a wrist splint, written information for carers and no planned follow up. Next day x-ray review acted as a safety net for misdiagnosed or less stable fractures. This has now been validated with a retrospective review of treatment for distal radial # within the ED. Patients were identified through the Emergency department’s electronic discharge record. Over a 9 month period 260 patients were identified with metaphyseal distal radial and/or ulna injuries to which a non orthopaedic junior doctor might be expected to apply the Buckle Fracture Algorithm. Of these 161 had isolated distal radial fractures suitable for treatment with a wrist splint. 118 were correctly identified and treated in the ED. 43 patients were sent to # clinic, of these 11 patients were discharged at the 1st visit, however 3 had 3 or more visits and 2 children had additional x-rays. Over this period 9 children were given splints inappropriately according to the protocol, most of these had stable injuries on reviewing the x-rays, 3 were identified and recalled for a cast. None of the children with injuries outside the protocol who were not recalled had an unplanned return with complications. Taking into account only those children who were correctly managed from the ED the estimated annual cost savings to the NHS for this hospital for this period is £40,784, compared to standard treatment before introduction of this protocol. If all children had been treated according to protocol the estimated cost savings would be £56096/yr

Correcting a malunited distal radial fracture usually requires osteosynthetic material applied on the dorsal side of the radius. However, contact of the material with the extensor tendons often produces irritation and rupture problems. The aim of this study is to evaluate the effectiveness of the specific osteosynthetic material (Trimed) in treating malunion of intra- or extra-articular fractures of the distal radius, after a corrective osteotomy. We examined 11 patients (7 females, 4 males), with average age of 42 years (ranging from 21 to 69 years old), 10 of which presented with symptomatic malunited distal radial fracture of a mean duration of 2.85 months (2–7 months). In one patient the malunited fracture was 30 years old. In 7 patients the malunited fracture was extra articular whereas in 4 patients it was intra articular. A corrective osteotomy was performed in all cases, followed by application of the special osteo-synthetic material by Trimed on the dorsal side of the radius. In seven patients iliac crest bone graft was used, whereas in four allografts were applied. Furthermore, five patients had to undergo additional surgical procedures. More specifically, shortening osteotomy of the ulna in 3 patients, radio-scapho-lunate fusion in 1 and excision of scaphoid with carpal tenodesis in 1 patient. After a mean follow-up of 15 months (6–27 months) the results were evaluated based on (Fernadez 2001), pain, range of motion, and grip strength. Excellent results (18–20 points) were observed in three patients, good results (15–17 points) in five patients and fair results (12–14 points) in two patients. We conclude that the use of this particular material provides satisfactory stability on the corrective osteotomy and because of its low profile it can be applied on the dorsal side on the radius without interfering with the extensor tendons

Introduction. Several clinical and radiological studies have confirmed the benefits of using Volar Locking Plates (VLPs) to treat unstable distal radius fractures. The “theoretical” advantage of VLPs compared to standard plate fixation is that VLPs, through their design, intrinsically provide angular stability for most fracture configurations including comminuted fractures and, quite possibly, osteoporotic fractures. However few studies have compared the clinical results of patients of different ages who have been treated using VLPs. Aim. The aim of this study was to compare the clinical outcomes of VLP fixation of displaced distal radius in younger (<59 yrs) and older (>60yrs) patients. Patients & Methods. We reviewed 78 consecutive patients who had undergone ORIF of their displaced distal radial fractures using a VLP. All patients were reviewed at predetermined time points by an independent observer and the findings at 6 months are presented. In addition to documenting the standard demographics for each patient and classifying the fractures using the OTA/AO system, wrist function was assessed using Range of Movement (ROM), Grip strength (GS), the Modified Gartland & Werley score (MGWS), the Patient Rated Wrist Evaluation (PRWE), the Quick DASH scores, and overall scores of wrist Pain and Function using Visual Analogue Scores (VAS). Results. 43 patients were under 60 years of age and 35 patients were 60 years or over. The proportion of extra-articular to intra-articular fractures were similar for both age groups. There was little difference in terms of patient perception of Pain and Function, or ROM, MGWS (7.2 versus 6.9), PRWE (24 versus 23.6) and quick DASH scores (17.3 versus 19.1) between the two groups at 6 months. The younger group did have significantly better grip strength, but when compared as a percentage of the uninjured wrist, the results were also similar (83% vs 80%). Conclusions. VLPs are a suitable option for fixing distal radial fractures in older patients (>60yrs) and the clinical results appear to be just as good as they are in younger patients

Introduction: We present the world’s largest current series of open distal radial fractures (ODRF), aiming to describe the epidemiology and outcomes of these injuries. Methods: Patients with ODRF treated at the Edinburgh Orthopaedic Trauma unit between 1990 and 2009 were identified from computer records. All patients aged over 13 with juxta-articular and metaphyseal fractures were included – diaphyseal injuries were excluded. The following information was retrieved from notes and radiographs: patient demographics; co-morbidities; mechanism of injury; AO classification; other injuries; time to A& E treatment; time until surgery; antibiotic use; Gustillo and Anderson (GA) grade; surgical treatment; complications; further surgery; functional outcome. Results: 201 patients were included. The average age was 65.5 years, 75% were female. 69% resulted from simple falls, 15% falls from height, 6% sporting injuries and 9% from road traffic accidents. 73 % were GA-1, 26% were GA-2, 1% GA-3. The commonest fracture pattern was AO 23-C2. 41% underwent definitive debridement within 6 hours, 46% in 6 to 24 hours, 13% waited longer. 30% were treated by ORIF, 38% with non-bridging fixator, 29% by bridging fixator and 3% by MUA and plaster. 43% of wounds were closed primarily, 47% were left open, 8% required delayed closure, 2% required skin grafting. Follow-up averaged 16.5 weeks. 14% suffered superficial infections, 1.3% suffered deep infection. Predictors of infection included primary closure and the use of an external fixator. Functional outcome was variable. Discussion: Most open distal radial fractures occur in elderly women after a simple fall. Serious infection rates are low

There is no consensus on the benefit of arthroscopically assisted reduction of the articular surface combined with fixation using a volar locking plate for the treatment of intra-articular distal radial fractures. In this study we compared the functional and radiographic outcomes of fluoroscopically and arthroscopically guided reduction of these fractures. Between February 2009 and May 2013, 74 patients with unilateral unstable intra-articular distal radial fractures were randomised equally into the two groups for treatment. The mean age of these 74 patients was 64 years (24 to 92). We compared functional outcomes including active range of movement of the wrist, grip strength and Disabilities of the Arm, Shoulder, and Hand scores at six and 48 weeks; and radiographic outcomes that included gap, step, radial inclination, volar angulation and ulnar variance. . There were no significant differences between the techniques with regard to functional outcomes or radiographic parameters. The mean gap and step in the fluoroscopic and arthroscopic groups were comparable at 0.9 mm (standard deviation. (sd). 0.7) and 0.7 mm (. sd. 0.7) and 0.6 mm (. sd. 0.6) and 0.4 mm (. sd. 0.5), respectively; p = 0.18 and p = 0.35). . Arthroscopic reduction conferred no advantage over conventional fluoroscopic guidance in achieving anatomical reduction of intra-articular distal radial fractures when using a volar locking plate.

The June 2014 Wrist & Hand Roundup360 looks at: aart throwing not quite as we thought; two-gear, four-bar linkage in the wrist?; assessing outcomes in distal radial fractures; gold standard Swanson’s?; multistrand repairs of unclear benefit in flexor tendon release; for goodness’ sake, leave the thumb alone in scaphoid fractures; horizons in carpal tunnel surgery; treading the Essex-Lopresti tightrope; wrist replacement in trauma? and radial shortening reliable in the long term for Kienbock’s disease

A prospective randomised study was undertaken of patients with displaced Colles’ type distal radial fractures. Group 1 underwent bridging external fixation with a Pennig device; group 2 underwent manipulation and plaster immobilisation. All patients were initially treated for 6 weeks and reviewed regularly for 12 months. At a mean of 7.8 years 86 fractures were available for review (36 treated by fixator and 50 treated in plaster). They were assessed to determine the anatomical and functional outcome of their wrist and also the incidence of post-traumatic degenerative change. The patients had standard anteroposterior and lateral radiographs taken, to allow standard measurements to be made. The degree of arthritic change was also documented. An independent physiotherapist carried out a functional assessment, consisting of range of movement and grip strength in both wrists. A Gartland and Werley demerit score was calculated, 94% of patients in each group had an excellent or good outcome. Patient satisfaction was comparable, 94% in the fixator and 92% in the plaster group were entirely satisfied. Although a significant difference was found in terms of radial shortening between the groups, favouring the fixator group (p< 0.05), shortening of > 2mm did not adversely effect the functional outcome. However bridging external fixation did not improve the dorsal angulation in this study. No other radiological or functional parameter showed a statistical difference between the groups. One patient in this series developed symptomatic post-traumatic arthritis. Grade 1 radiological signs (Knirk & Jupiter) occurred in 25% of patients but only half of these had sustained intra-articular fractures. In conclusion: no overall long term benefit has been found to treating Colles’ type distal radial fractures with bridging external fixator as compared to plaster immobilisation

Aim: To compare the outcome of open reduction and internal fixation with MUA and k-wire stabilisation of dorsally displaced distal radial fractures. Methods: A review of patients that had ORIF or MUA and k-wire stabilisation for dorsally displaced distal radial fractures was carried out and patients with a follow period of more than 6 months were selected for this study. The patient history and the management of the injury were obtained and the wrist examined. Each patient completed a patient-rated wrist evaluation form and the range of movement and strength of the wrist was determined by the senior occupational therapist. Standard radiographs were obtained and volar tilt, radial inclination and radial length were measured. Results: This study provides results on 24 patients, which were grouped according to the two different surgical procedures; ORIF and MUA and k-wire stabilisation. The procedure undertaken depended on consultant preferences and in the majority of cases patients were treated with MUA and k-wire stabilisation. Patients of both groups were of similar age and all sustained either a low or medium energy injury. All patients from each group received physiotherapy post operatively. There was no significant difference between both groups for range of movement and grip strength. There was also no difference between the patient’s perception of pain and function which was assessed using the patient rated wrist evaluation (PRWE). Radiologically, the k-wire stabilisation group averaged better volar tilt compared with the ORIF group. For radial height and inclination the outcome was similar. Conclusion: MUA and k-wire stabilisation has been the most popular surgical management for unstable dorsally displaced fractures of the distal radius. More recently ORIF with the locking compression plate has been used with good results. This study showed that the outcome of ORIF and MUA and k-wire stabilisation were similar and therefore either surgical management can be used with good results

Background: Extraarticular distal radius fracture is the second most common osteoporotic fracture seen in the elderly patients. Purpose: To establish relationship between radiological parameters and final functional outcome in conservatively treated displaced extraarticular distal radial fractures in elderly patients. Methods: Twenty-two wrists with displaced extraar-ticular distal radial fractures in twenty sedentary, low demand elderly patients treated with manipulation under anaesthesia and plaster application between May 1999 and June 2000. The case notes and radiographs of these patients were assessed retrospectively and subjective outcome was evaluated with validated DASH Questionnaire at 3 years post- reduction. Overall satisfaction, ability to return to the previous level of activity and concern over wrist appearance was further analyzed. Only those patients with more than 5 mm of shortening and more than 15 degrees of dorsal angulation at initial radiographs were included. Results were analysed using Pearson Correlation Sig.(2 –Tailed) formula. Results: There were 16 female and 4 male patients with a mean age of 71 years. The mean follow-up was 3 years. DASH score of less than 25 was seen in 14, between 25-50 in 3 and between 50-75 in 3 patients with mean of 21.426 and standard deviation of 22.353. Despite residual deformity in some patients, there was high degree of patient satisfaction consistent with low level of DASH score found in 71% patients. It was also noticed that Males in the study group were younger and have lower dash scores. Patients with more than 5 mm of shortening and more than 15 degrees of dorsal angu-lation at initial radiographs showed no adverse correlation with subjective outcome. Statistical analysis of the results confirmed that higher the age lower the DASH score there by better functional result. Conclusion: It was noted that the higher the age the lower the dash score. Radiological picture and functional outcome are found to be two independent variables in the elderly subgroup of patients with displaced extrar-ticular distal radius fractures. Nonoperative treatment yields satisfactory results with high patient satisfaction rate and is advocated in elderly patients

The Pronator Quadratus (PQ) is commonly damaged in the surgical approach to the distal radius during volar plating. This study explored the functional strength of the PQ muscle, 12 months after volar plating of a distal radial fracture. Testing of treated and contralateral forearms was carried out using a custom-made Torque Measuring Device (TMD) and surface Electromyography (sEMG). To assess both the direct and indirect function of PQ in participants treated with volar plating and compared to the contralateral non-injured forearms. The angle of elbow flexion was varied from 45o, 90o and 135o when measuring forearm pronation. Mean peak torque of the major pronating muscles, PQ and Pronator Teres (PT) was directly measured with the TMD and the indirect activation of the PQ and PT was measured with sEMG. In total 27 participants were studied. A statistically significant reduction in mean peak pronation torque was observed in the volar plated forearms (P<0.05 SE 0.015, CI 95%). This is unlikely to be of clinical significance as the mean reduction was small (13.43Nm treated v 13.48Nm none treated). Pairwise comparison found no statistically significant reduction in peak torque between 45o, 90o and 135o of elbow flexion. There was an increase in PQ muscle activation at 135o compared to 45o elbow flexion. The converse was identified in PT. The small but statistically significant difference in mean peak torque in treated and uninjured forearms is unlikely to be of clinical significance and results suggest adequate functional recovery of the PQ after volar plating

Distal radial fractures account for 17% of all fractures treated, with peaks in the bimodal distribution corresponding to young and senior patients. External fixation is one of the best techniques to allow quick patient recovery and is necessary for complex fractures, such as that of the distal radius. However, the safe removal time for these frames remains unclear. A conservative approach commonly leaves the external fixator in place for six weeks, which may be unnecessarily prolonged and lead to increased complications. The aim of this work is to develop a technique to quantify, objectively, a safe removal time for these frames. Studies have been conducted on external fixation of tibial fractures, however there are differences that do not allow transfer of these studies to the external fixation of distal radial fractures. These differences include configuration of the fixation frame, bone and fracture geometries, and the application and transfer of the load to the bone. In this work, the dynamic transfer of the load between the fractured bone and the fixator is investigated. An instrumented grip and a measuring device have been developed to monitor the axial force and displacement when the patient applies a load. Using measurements collected by the instrument and data specifying the frame geometry, a finite element model is used to calculate the load carried by the fixator and by the bone, and the rigidity of the new callus is determined. Plotting the rigidity on semi-logarithmic scale the healing rate can be established. This technique has been successfully verified in a laboratory simplified structure representative of bone fracture. The rigidity of several intra-gap materials has been estimated experimentally using the technique, and the results compared to the real value of the material. These measurements do not interfere in any way with the patient treatment and they can be collected from the first day after the operation. The technique has been tested on 14 volunteer patients and the increase in callus rigidity can be detected by measurements during treatment using the technique described. A randomised prospective study has been initiated to validate this technique and investigate the healing process. A positive outcome would enable the rigidity of the new callus bone and the healing rate to be monitored during clinical assessment. Any healing delay or non-union could be promptly detected, improving the quality of the treatment

Restoration of normal anatomy following a distal radial fracture is an important factor in determining functional recovery. However, current methods of assessing dorsal tilt and displacement require ‘true’ lateral radiographs, and important reference points are often obscured by metalwork. Aims: to investigate if an easily identifiable and predictable relationship exists in the normal wrist between the distal radius and lunate; and if so,to compare fractured wrists (pre and postoperatively)using conventional and new assessment methods. 22 patients with displaced distal radial fractures treated by ORIF, were included. Patients had pre and postoperative radiographs taken of the injured and uninjured wrists. From lateral radiographs, measurements were performed using the PACS system. A line was superimposed upon the dorsal radial cortex 2cm proximal to the wrist passing distally. The following measurements were performed: lunate height, distance from the ‘line’ to the superior and inferior poles of the lunate, and conventional measurements of dorsal tilt and angulation. Uninjured wrist: Most noticeably the dorsal radial line always passed superior to the lunate, mean distance of 3.27mm (1.75-6.6mm). As a ratio, the distance from the line to the superior pole of the lunate divided by the distance to the inferior pole (‘lunate ratio’) had a mean of 0.16 (0.11-0.19). Fractured wrist, PreORIF: Using conventional methods, the mean fracture displacement was 2.64mm (0-5.1mm) and the mean dorsal tilt was 23.3 degrees(4 degrees volar tilt to 43 degrees dorsal tilt). Using the dorsal reference ‘line’, in all cases the lunate was either above or transected by the line; mean lunate ratio of 1.61 (0.54-8.05). The mean height of the lunate projecting dorsal to the line was 9.5mm (6.1-16.1mm). Fractured wrist, PostORIF: Apart from one radiograph, the ‘line’ passed superior to the lunate; mean distance of 2.64mm (0-3.9mm), with a mean lunate ratio of 1.13 (0.61-2.74). These measurements correlated well with measurements of dorsal tilt and displacement. Our study suggests that there is a strong relationship between the distal radius and the lunate that could be used to assess fracture displacement and quality of reduction. Its main advantages are simplicity and ease of use despite the presence of metalwork

Percutaneous wiring is a successful technique for the management of distal radial fractures. Practice differs according to surgeon preference as to whether the wires used are buried or protruding. To assess patient satisfaction with wither technique, we prospectively randomised 52 consecutive patients undergoing percutaneous wiring for distal radius fractures with regard to whether the wires were buried or not. Patients with a distal radial fracture managed with percutaneous wire fixation and casting only were randomly allocated to have the wires buried or protruding. The fractures were classified according to Frykmn’s classification of fractures of the distal radius, and there were no differences between the groups (p=0.9). The total number of patients studied was 52, with a mean age of 56.6 years (range 19–84). The female: male ratio was 38:13. Twenty-five (48%) patients had percutaneous wiring of their fracture with the Kirschner wires buried and 27 (52%) had the wires protruding. Cast and wire fixation were removed at a mean duration of 5.8 weeks in an outpatient setting. Patients recorded whether they experienced pain during the period of wire fixation or pain during the removal of wires on a visual analogue scale. Fifteen patients reported pain during the period of fixation (55.5%), the severity ranged between 2–8 (mean 3.8) with no significant difference between the groups (p=0.8). All patients with buried wires compared with 10% of those protruding wires required local anaesthesia in the operating theatre for removal (p=0.03). Superficial infection was diagnosed in 4 patients with no significant difference between groups (p=0.14). Buried wires are typically advocated to prevent pin site infections and to improve patient comfort and satisfaction. However, we found no difference between the study groups with regard to patient satisfaction, pain during the period of fixation or pin-site infections. Furthermore, all patients in the buried wire group required local anaesthesia for removal with some of these necessitating a visit to the operating theatre. We therefore feel that burying these wires confers no advantage while adding to the complexity, time and cost of removal and recommend leaving wires protruding through the skin

Aims: In recent years, volar locking plates have increased in popularity for the treatment of displaced distal radial fractures. The angular stability of the screws help maintain reduction permitting early mobilisation. The aim of this study was to assess functional outcome using both subjective and objective methods. Methods: The study was a prospective cohort study. Over a 2 year period 110 patients with closed, displaced distal radial fractures were considered suitable for treatment with the distal radius volar locking plate. Of these, 51 patients were followed up for a full 12 months. One year post-operatively all patients were reviewed and both subjective and objective measurements made:. Subjective:. Pain – visual analogue scale (VAS) (0 = no pain, 10 = worst pain ever). Overall function – patients’ perception – VAS (0 = no function, 100 = full function). Objective: Strength – grip and pinch – measured objectively as a percentage of the uninjured side. Range of Motion – Flexion, extension, pronation and supination – measured objectively as percentages of the uninjured side. For the purpose of this analysis, the fractures were divided into intra- and extra-articular fracture patterns based on the initial pre-operative X-rays. Results: The mean age was 55 years (28 – 83), 36 were female and 15 male. Of the fractures, 26 were extra-articular and 25 intra-articular. 28 of the 51 patients had a period of physiotherapy post-operatively. 23 patients were either not referred to physiotherapy or failed to attend. Subjectively 75% of patients had an excellent result with a pain VAS score of 0–1/10 (mean 0.9 for extra-articular and 1.2 for intra-articular) and an overall function VAS score of 9–10/10 (mean 92% for extra-articular and 86% for intra-articular). Objective outcome measures were also very good. The results for the extra-articular group showed a mean grip strength of 85%, a mean pinch grip of 91%, a mean flexion of 82%, a mean extension of 88%, a mean pronation of 98% and a mean supination of 98%. The results for intra-articular fractures showed a mean grip strength of 80%, a mean pinch grip of 88%, a mean flexion of 78%, a mean extension of 83%, a mean pronation of 94% and a mean supination of 93%. Conclusions: Overall patients made an excellent recovery. The majority of patients had little or no pain and almost complete return to function at 12 months post-operatively. Interestingly, individual patient demographics (age, sex, fracture type, physiotherapy) did not make a statistically significant difference to the outcome measures. This study confirmed excellent functional results comparable with other methods of fixation for extra-articular fractures, but it also showed good results with the more complex intra-articular fractures

Introduction The purpose of this paper is to describe our management of complex fractures of the distal radius and ulna using a combined type of stabilization, external with a Pennig fixator, internal with radial augmentation with plate. The patient have substained a several general trauma or an high energy scheletral trauma upper limbs. Treatment In a period from 24 july 2002 to today 8 october 2004 (26 months) we have treated surgically 93 wrists with distal radial fractures in 85 patient. 4 patients bilaterally, 3 patients have substained a secondary reprease for lacking the initial reduction and 2 in two programmed timing. 46 wrists with radial internal fixation single or double plate (in one case trhee plate). 12 plate with pin or single screw in augmentation. 3 cases with only screw artroscopically assisted. 14 cases with only external fixator with or without pin. 18 wrist with a combination of radial internal fixation (plate) and external fixation with Pennig, in complex distal radial-ulna fracture (2 exposed). In 5 wrists there were associated and treated navicular fracture or intracarpal ligaments injury. 1 pazient have sustained an ipsilateral forearm fracture, epiphiseal distal radial fracture, trans scapho-lunate dislocation and controlateral transcapho-lunate dislocation. 1 patient have sustained ipsilateral navicular-fisrt metacarpal-radial and ulna fracture. The most patients (...) have been treated from the first Author. The patients were controlled from minimum of 6 month up a maximum of 39 months. We have adapted in our evaluation the Dash score system. The main problem, in the follow up results is a lack of prono-supination that stresses the importance of a perfect reduction of distal radio-ulnar joint to begin early a phisiotherapy. Clinical results In conclusion our experince in timing of treatment indicate that is important fixate the lesions earlier, whenever the priority of treatment on severly injured pazients are respected. We believe that a combination of the two fixation system allow an optimal external stabilization in the first week (So the terapist can move the patients in intensive care room). Secondary the internal fixator allows an anatomical reduction with a stable fixation in the secondary kinesiterapeutic time protocol of high energy trauma to distal forearm, in particular in politraumatized patients is:. - closed reduction and short cast or external fixator if exposed or severe instable, on the day of injury during or just following generally stabilization. - if possible e Tc 3D dimensional scan (our patients have substained a lot of tc scan for other trauma). - internal reduction and stabilitation a fews days later when the local swelling or skin damage and general condition allow it (from 2 to 7). - removal of external fixator between 3–4 week and begin a complete fkt

Purpose. To assess outcomes of manipulating upper extremity fractures with conscious sedation compared with formal reduction and casting in theatre under general anaesthesia and image intensifier control. Method. Prospective six month period all patients presenting to the Emergency Department with a both bone forearm or distal radial fracture that was deemed suitable for closed reduction and casting where included in the study. All fractures deemed to require instrumentation were excluded. Results. We identified 56 fractures, 13 of the distal radius and 43 both bone forearm. 22 where treated in theatre with 34 treated in ED. Age range 2–14 years. We had 1 re fracture in the ED group and 1 re fracture in the theatre group. All fractures united within acceptable limits. We had no re operations in either group. No complications from the procedural sedation or anaesthesia. Mean time to treatment in theatre group was 18 hours Vs 3 hours in the ED group (P< 0.05). Conclusion. The use of procedural sedation, closed reduction and casting has no adverse effects on union, malunion, reoperation or anaesthetic complications. It is however significantly quicker, significantly lower in cost when compared with admission and treatment in theatre and has less negative psychological impact on the child. We recommend treatment in Emergency Department for all fractures of the forearm and distal radius that can be managed by closed reduction and casting in children who are safe to undergo procedural sedation

Paediatric wrist fractures are routinely managed with closed reduction and a molded cast. Gap(GI) and Cast indices(CI) are useful in predicting re-displacement following application of cast. Over 6 months we audited the efficacy of molded cast application following closed reduction of distal radial fractures in paediatric patients. The standard was that proposed by Malviya et al where GI >0.15 and CI >0.8 indicate an increased risk of re-displacement. Age, date and time of operation and surgeon's grade were collected. Pre-op displacement, post-reduction GI and CI and subsequent re-displacement were measured using imaging. Post audit intended changes to practice were presented to all surgeons, a “one-pager” was placed above scrub sinks. Re-audit was conducted at 1 year. The audit and re-audit included 28 and 24 patients respectively. Cast molding (CI) improved minimally following intervention (32% to 29%). Cast padding (GI) improved significantly (82% to 63%). Loss of reduction decreased slightly (14% to 12%), this was not accurately predicted by GI and CI in the re-audit. Audit demonstrated that casts were loose, over-padded and did not hold reduction adequately. Re-audit demonstrated that tighter, less padded but still inadequately molded casts were being applied with minimal change in loss of reduction

Distal radius fractures are the most common fracture of the upper extremity. Malunion of the distal radius is a common clinical problem after these injuries and frequently leads to pain, stiffness loss of strength and functional impairments. Currently, there is no consensus as to whether not the mal-aligned distal radius has an effect on carpal kinematics of the wrist. The purpose of this study was to examine the effect of dorsal angulation (DA) of the distal radius on midcarpal and radiocarpal joint kinematics, and their contributions to total wrist motion. A passive wrist motion simulator was used to test six fresh-frozen cadaveric upper extremities (age: 67 ± 17yrs). The specimens were amputated at mid humerus, leaving all wrist flexor and extensor tendons and ligamentous structures intact. Tone loads were applied to the wrist flexor and extensor tendons by pneumatic actuators via stainless steel cables. A previously developed distal radius implant was used to simulate native alignment and three DA deformity scenarios (DA 10 deg, 20 deg, and 30 deg). Specimens were rigidly mounted into the simulator with the elbow at 90 degrees of flexion, and guided through a full range of flexion and extension passive motion trials (∼5deg/sec). Carpal motion was captured using optical tracking; radiolunate and capitolunate joint motion was measured and evaluated. For the normally aligned radius, radiolunate joint motion predominated in flexion, contributing on average 65.4% (±3.4). While the capitolunate joint motion predominated in extension, contributing on 63.8% (±14.0). Increasing DA resulted in significant alterations in radiolunate and capitolunate joint kinematics (p<0.001). There was a reduction of contribution from the capitolunate joint to total wrist motion throughout flexion-extension, significant from 5 degrees of wrist extension to full extension (p = 0.024). Conversely, the radiolunate joint increased its contribution to motion with increasing DA; significant from 5 degrees of wrist extension to full extension as the radiolunate and capitolunate joint kinematics mirrored each other. A DA of 30 degrees resulted in an average radiolunate contribution of 72.6% ± 7.7, across the range of motion of 40 degrees of flexion to 25 degrees of extension. The results of our study for the radius in a normal anatomic alignment are consistent with prior investigators, showing the radiocarpal joint dominated flexion, and the midcarpal joint dominated extension; with an average 60/40 division in contributions for the radiocarpal in flexion and the midcarpal in extension, respectfully. As DA increased, the radiocarpal joint provided a larger contribution of motion throughout flexion and extension. This alteration in carpal kinematics with increased distal radius dorsal angulation may increase localised stresses and perhaps lead to accelerated joint wear and wrist pain in patients with malunited distal radial fractures

This case series aim to report our experience with the use of fragment specific fixation plating system and cancellous bone autograft in the elective treatment of distal radius malunions. Fourteen patients who underwent distal radial corrective osteotomy by one surgeon were followed up retrospectively. All patients had elected for this procedure for the treatment of malunions of previous distal radial fracture. The follow up assessments include each patient’s subjective functional outcomes, the objective strength and range of motion testing, and the radiographic parameters. These subjective functional outcome data collected as measured by the Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH) were compared with each patient’s pre-operative status. The motion, strength and radiographic appearances were assessed in relevance to the contralateral arm

Magnetic resonance imaging (MRI) validation of a novel method of assessing Distal Radial Fracture (DRF) reduction using the hypothesised constant relationship between the dorsal radial cortex (DC) and the superior pole of the lunate (SL). MRI scans of 28 normal wrists were examined. Scans included the distal third of the radius to the proximal carpal row. Beginning 5cm proximal to the distal radius articular surface, a line was superimposed upon the DC extending distally through the metaphyseal flare. Lunate height (LH) and distance from the DC line to the SL (DC-SL) were measured at 5-degree rotational increments around the radial shaft central axis to a total of 30 degrees of supination and pronation (S+P). The DC-SL/LH ratio was compared to 0 degrees (anatomical lateral) using the two-tailed paired student t-test. There was no significant difference in DC-SL:LH between 0 degrees of rotation and any 5-degree increment up to 30 degrees of S+P (lowest p=0.075). The DC line lay consistently dorsal to the SL. A constant DC-SL relationship exists with up to 30 degrees of S+P. This reference can be quickly and accurately used to assess DRF reduction in poorly-taken films with malrotation up to 30 degrees from anatomical lateral. Research comparing DC-SL distance with volar tilt to assess DRF reduction is needed

Aim. Fixation of distal radial fractures via the volar approach has become a commonly performed procedure over the past few years. This study is to highlight potential pitfalls with this ‘everyday’ procedure and to perhaps temper over-enthusiasm for plating all wrist fractures. Method and materials. 164 consecutive cases of wrist fracture treated by means of fixed angle volar fixation were looked at. In each case any recorded complication prior to completion of treatment was documented. The complications were divided into major and minor depending on the severity and long-term outcome and overall result. Results. With critical analysis there were 32 major complications: 12 required further surgery; 1 iatrogenic radial artery injury; 1 iatrogenic palmar branch of median nerve injury; 2 complex regional pain syndromes; 16 patients with less than 60 arc of movement. In addition 12 minor complications including hypertrophic scars, suture abscess and intermittent minor discomfort were also recorded. Conclusion. While volar distal radial fixation is well accepted and indeed commonly performed, the procedure is not without complications. We must pay meticulous attention to detail and technique to optimise results

Intro. Distal radial fractures are a commonly encountered fracture & anatomical reduction is the standard. Dorsal angulation is the traditional method of assessment but is inaccurate in rotated lateral xrays. Previously a relationship has been demonstrated between the dorsal cortex (DC) of the radius & the superior pole of the lunate (SL) & its sensitivity for assessing dorsal angulation & translation. Hypothesis. A constant anatomical relationship maintained between the DC and the SL when rotated up to 30 degrees from standard lateral?. Methods. MRI scans of 28 wrists including the distal third of the radius to the proximal carpal row. Beginning 5cm proximal to the distal radius articular surface, a line was superimposed upon the DC extending distally through the metaphysis. Lunate height (LH) & distance from the DC line to the SL (DC-SL) were measured at 5-degree rotational increments around the radial shaft central axis to 30 degrees of supination & pronation (S+P). The DC-SL/LH ratio was compared to 0 degrees (anatomical lateral) using the two-tailed paired student t-test. Results. No significant difference in DC-SL:LH between 0 degrees of rotation and any 5-degree increment up to 30 degrees of S+P (lowest p=0.075). The DC line lay consistently dorsal to the SL. Conclusion. A constant DC-SL relationship is maintained with up to 30 degrees of S+P. This reference can be quickly and accurately used to assess DRF reduction in poorly-taken films with malrotation

Summary. These data suggest that PTH treatment for stimulation of bone healing after trauma is not much dependent on mechanical stimulation and therefore, roughly equal treatment effects might be expected in the upper and lower extremities in humans. Introduction. Stimulation of bone formation by PTH is known to, in part, act via increased mechanosensitivity. Therefore, unloading should decrease the response to PTH treatment in uninjured bone. This has served as a background for speculations that PTH might be less efficacious for human fracture treatment in unloaded limbs, e.g. for distal radial fractures. We analyzed if the connection with mechanical stimulation also pertains to bone formation after trauma in cancellous bone. Methods. 20 male SD rats, 8 weeks old, had one hind leg immobilised via Botox injections. At 10 weeks of age the rats received bilateral screw implants into their proximal tibiae. Half of the rats were given daily injections of 5µg/kg PTH(1–34). After two weeks of healing, the tibias and femurs were harvested. Mechanical testing of screw fixation (pull-out) and µCT of the cancellous bone of the distal femurs was performed. Results. The pull-out forces served as a read-out for cancellous bone formation after trauma. PTH more than doubled the pull-out force in the unloaded limbs (from 14 to 30 N), but increased it by less than half in the loaded (from 30 to 44 N). These force values are not limited by a ceiling effect, and the difference in relative effect of PTH was significant (p = 0.03). Discussion/Conclusion. PTH appeared to exert a greater effect on bone healing in the unloaded limbs, compensating for the lack of mechanical stimulation. These data suggest that PTH treatment for stimulation of bone healing after trauma is not much dependent on mechanical stimulation. Therefore, roughly equal treatment effects might be expected in the upper and lower extremities in humans

With the advent of locked volar radial plates there has been a wave of enthusiasm in the fixation of distal radial fractures with these devices. This study was designed to look at potential complications and pitfalls of this treatment modality. 80 consecutive cases treated by the author with locked volar radial plates were analysed. Complications were divided into major and minor groups and recorded exhaustively. Major complications included 6 patients requiring further wrist related surgery, 1 patient with an iatrogenic radial artery injury, 1 patient with an iatrogenic palmer branch of median nerve partial injury, 1 patient with a complex regional pain syndrome and 6 patients with a less than adequate return of range of movement. ^ minor complications were recorded. With attention to detail and by avoiding several recurring pitfalls volar locked plating is a safe and effective procedure

Introduction: Radial shortening has been associated with a poor functional outcome following a fractured distal radius. Traditionally, outcome has been measured using doctor-based scores such as the Gartland and Werley Scoring System or modifications thereof. Aims: The aim of this study is to compare patient based outcome scores with the Frykman class of the fracture and radial shortening both at injury and fracture union. Methods: We followed up 60 patients over 55 who underwent closed reduction and k-wire fixation of distal radial fractures. Outcome was recorded by the Patient Rated Wrist Evaluation (PRWE) score, a validated subjective outcome measure. Results: No association was found between radial shortening either at injury or fracture union with subjective outcome score but there was a significant association between Frykman Classification and outcome (p< 0.05). Discussion: Our results showed that for distal radius fractures that united with a moderate degree of radial shortening, increasing Frykman Class was associated with a worse functional score

Anteriorly displaced fractures of the wrist can be treated by the Kapandji technique of percutaneous intrafocal pinning with pins inserted through an anterior approach to give good reduction and stabilisation of the fracture. We have modified this technique by placing the pins through a posterior approach which decreases the risks of neurovascular damage. We have used this method to treat six children with distal radial fractures showing anterior displacement or instability. Good anterior stabilisation was achieved. The pins were removed at an average of eight weeks and the patients were then able to return to full activity. This simple technique can be used for unstable fractures after the failure of conservative treatment or in bilateral fractures in adolescents

Outcome following wrist fractures is difficult to assess. There are many methods used to assess outcome following distal radius fractures, but may be that simply asking the patient for their level of satisfaction may be enough. We looked at 50 wrist fractures at 12 weeks post injury and compared their level of satisfaction with various respected outcome measures (Gartland and Verley, Sarmiento, Cooney, Patient-Rated Wrist Evaluation, Hand Function Score, and Disability of Arm Shoulder and Hand Score) to determine whether there was a correlation with their level of satisfaction. The aim was to determine which wrist scoring system best correlates with patient satisfaction and functional outcome and which individual variables predict a good outcome. Forty-five females and 5 males with a mean age of 66 years (range 19 to 93 years) were included in the study. Multivariate regression analysis was carried out using SPSS 17. Patient satisfaction correlated best with the MacDermid, Watts and DASH scores. The variables in these scoring systems that best accounted for hand function were pain, ability to perform household chores or usual occupation, open packets and cut meat. The McDermid, Watts and DASH scores provide a better measure of patient satisfaction than the Gartland and Verley, Sarmiento and Cooney scores, however they are all time consuming, complicated and may indeed not be necessary. The four most important questions to ask in the clinic following wrist fractures are about severity of pain, ability to open packets, cut meat and perform household chores or usual occupation. This may provide a simple and more concise means of assessing outcome after distal radial fractures

In a prospective trial, biodegradable polyglycolic acid rods were compared with Kirschner wires for fixation of wrist fractures (Frykman types I, II, V and VI). Fifteen patients were randomly assigned to each treatment group. There was no significant difference between the groups with regard to age, sex ratio and fracture type. Kapandji's pinning technique was used in all cases. There were no significant differences in the results obtained in both groups at final follow-up. At three months and six months the functional results of the Kirschner-wire group were, however, significantly better (p < 0.05), due to numerous transient complications from foreign-body reactions to the polyglycolic acid rods. The use of polyglycolic acid rods is therefore not recommended for the fixation of distal radial fractures

Osteoporosis is an increasing problem due to increasing age and inactivity. Distal radial fractures are often the first symptom of this disease. Medical treatment can reduce the risk of further fractures (including hip fractures with the associated mortality and morbidity). To develop a method for accurate assessment of bone density from routine wrist radiographs:. Various bone substitutes were tested until one was found that gave reasonable density matches with fresh bone over a limited X-ray kV range;. Twenty patients with distal radius fractures had the bone substitute placed beside the wrist being X-rayed. Wrist and radius thickness were measured from the radiograph. This was combined with the optical density of the distal radius (relative to the bone substitute) to calculate a value for the bone density. The patients subsequently underwent a DEXA scan of the contralateral (uninjured) wrist. [The X-ray calculated bone density and the DEXA density compare well. (R> 0.5]. Conclusion: This technique gives reasonably accurate results. It is not yet ready for clinical practice. A larger study is required to improve the accuracy of this technique, perhaps comparing results with lumbar spine DEXA

Fifty patients with complex distal radial fractures treated by primary external fixation were compared with 50 with similar fractures treated by closed medullary pinning. All the patients had Frykman type-VIII injuries. The two groups were similar in regard to demographic characteristics and the method of treatment was randomly chosen. All the fractures healed within three months. In the external fixation group 92% of fractures healed in excellent alignment as did 88% of the medullary pinning group. Both groups had similar results with respect to eventual function, range of motion, and grip strength. Complications and complaints were fewer and the estimated costs of treatment were significantly less in the medullary pinning group. More patients were satisfied with closed medullary fixation than with external fixation

The conventional treatment of comminuted fractures in the distal radius has been unsatisfactory. We therefore made a prospective study using the principle of ligamentotoxis and primary cancellous bone grafting as the uniform method of treatment. Ligamentotaxis was maintained by using an external fixator for three weeks only, after which a carefully monitored programme of rehabilitation was given. We have reviewed 72 consecutive distal radial fractures after a follow-up of 7 to 40 months (average 11 months). Reduction had been maintained during healing and over 80% of patients regained full range of movement in hands, wrists and forearms with strong and pain-free wrist function. Complications were infrequent and gave no real problems. We conclude that distraction, external fixation and bone grafting appears to be an excellent method of treating comminuted fractures of the distal radius
