Distal radius fractures (DRFs) are common injuries that represent 17% of all adult upper extremity fractures. Some fractures deemed appropriate for nonsurgical management following closed reduction and casting exhibit delayed secondary displacement (greater than two weeks from injury) and require late surgical intervention. This can lead to delayed rehabilitation and functional outcomes. This study aimed to determine which demographic and radiographic features can be used to predict delayed fracture displacement. This is a multicentre retrospective case-control study using radiographs extracted from our Analytics Data Integration, Measurement and Reporting (DIMR) database, using diagnostic and therapeutic codes. Skeletally mature patients aged 18 years of age or older with an isolated DRF treated with surgical intervention between two and four weeks from initial injury, with two or more follow-up visits prior to surgical intervention, were included. Exclusion criteria were patients with multiple injuries, surgical treatment with fewer than two clinical assessments prior to surgical treatment, or surgical treatment within two weeks of injury. The proportion of patients with delayed fracture displacement requiring surgical treatment will be reported as a percentage of all identified DRFs within the study period. A multivariable conditional logistic regression analysis was used to assess case-control comparisons, in order to determine the parameters that are mostly likely to predict delayed fracture displacement leading to surgical management. Intra- and inter-rater reliability for each radiographic parameter will also be calculated. A total of 84 age- and sex-matched pairs were identified (n=168) over a 5-year period, with 87% being female and a mean age of 48.9 (SD=14.5) years. Variables assessed in the model included pre-reduction and post-reduction radial height, radial inclination, radial tilt, volar cortical displacement, injury classification, intra-articular step or gap, ulnar variance, radiocarpal alignment, and cast index, as well as the difference between pre- and post-reduction parameters. Decreased pre-reduction radial inclination (Odds Ratio [OR] = 0.54; Confidence Interval [CI] = 0.43 – 0.64) and increased pre-reduction volar cortical displacement (OR = 1.31; CI = 1.10 – 1.60) were significant predictors of delayed fracture displacement beyond a minimum of 2-week follow-up. Similarly, an increased difference between pre-reduction and immediate post reduction radial height (OR = 1.67; CI = 1.31 – 2.18) and ulnar variance (OR = 1.48; CI = 1.24 – 1.81) were also significant predictors of delayed fracture displacement. Cast immobilization is not without risks and delayed surgical treatment can result in a prolong recovery. Therefore, if reliable and reproducible radiographic parameters can be identified that predict delayed fracture displacement, this information will aid in earlier identification of patients with DRFs at risk of late displacement. This could lead to earlier, appropriate surgical management, rehabilitation, and return to work and function

Background and Aims:. Forearm fractures are common in the paediatric population and most are treated in a moulded plaster of Paris (POP) cast. It is our concern that many casts applied by our registrars are sub-optimal and that we need to improve our training process. The aim of our study was to review the adequacy of forearm cast application in paediatric patients at our institution and to identify if there is a need for a more formal training program with regard to plaster cast application. Methods:. A retrospective review of control x-rays of forearm fractures treated at our institution was undertaken. X-rays that were reviewed were done as part of the routine treatment protocol. X-ray measurements to assess POP application were the cast index and the gap index. A cast index of > 0.81 and Gap index of > 0.15 were regarded as an indication of poor cast application. Results:. Adequate control X-rays of twenty eight patients with a forearm fracture were available. The average patient age range was 5–12 years. There were thirteen distal metaphyseal fractures, nine diaphyseal fractures and six Salter-Harris type fractures. Of the 28 patients, 20 patients had a poor cast index and 17 patients had poor gap index. In 12 patients both the gap and the cast index were unacceptable. Conclusion:. Our study suggests that paediatric forearm plaster cast application by registrars at our institution is inadequate. This indicates a need for a strategy to improve the training in plaster cast application amongst our registrars

Fractures of the forearm (radius or ulna or both) in children have traditionally been immobilised in plaster of Paris (POP) but synthetic cast materials are becoming more popular. There have been no randomised studies comparing the efficacy of these two materials. The aim of this study was to investigate which cast material is superior for the management of these fractures. We undertook a single-centre prospective randomised trial involving 199 patients with acute fractures of the forearm requiring general anaesthesia for reduction. Patients were randomised by sealed envelope into either a POP or synthetic group and then underwent routine closed reduction and immobilisation in a cast. The patients were reviewed at one and six weeks. A satisfaction questionnaire was completed following the removal of the cast. All clinical complications were recorded and the cast indices were calculated. There was an increase in complications in the POP group. These complications included soft areas of POP requiring revision and loss of reduction with some requiring re-manipulation. There was an increased mean padding index in the fractures that lost reduction. Synthetic casts were preferred by the patients.

This study indicates that the clinical outcomes and patient satisfaction are superior using synthetic casts with no reduction in safety.

Forearm fractures in children have a tendency to displace in a cast leading to malunion with reduced functional and cosmetic results. In order to identify risk factors for displacement, a total of 247 conservatively treated fractures of the forearm in 246 children with a mean age of 7.3 years (sd 3.2; 0.9 to 14.9) were included in a prospective multicentre study. Multivariate logistic regression analyses were performed to assess risk factors for displacement of reduced or non-reduced fractures in the cast. Displacement occurred in 73 patients (29.6%), of which 65 (89.0%) were in above-elbow casts. The mean time between the injury and displacement was 22.7 days (0 to 59). The independent factors found to significantly increase the risk of displacement were a fracture of the non-dominant arm (p = 0.024), a complete fracture (p = 0.040), a fracture with translation of the ulna on lateral radiographs (p = 0.014) and shortening of the fracture (p = 0.019).

Fractures of both forearm bones in children have a strong tendency to displace even in an above-elbow cast. Severe fractures of the non-dominant arm are at highest risk for displacement. Radiographs at set times during treatment might identify early displacement, which should be treated before malunion occurs, especially in older children with less potential for remodelling.

Redisplacement is the most common complication of immobilisation in a cast for the treatment of diaphyseal fractures of the forearm in children. We have previously shown that the three-point index (TPI) can accurately predict redisplacement of fractures of the distal radius. In this prospective study we applied this index to assessment of diaphyseal fractures of the forearm in children and compared it with other cast-related indices that might predict redisplacement. A total of 76 children were included. Their ages, initial displacement, quality of reduction, site and level of the fractures and quality of the casting according to the TPI, Canterbury index and padding index were analysed. Logistic regression analysis was used to investigate risk factors for redisplacement. A total of 18 fractures (24%) redisplaced in the cast. A TPI value of > 0.8 was the only significant risk factor for redisplacement (odds ratio 238.5 (95% confidence interval 7.063 to 8054.86); p < 0.001).

The TPI was far superior to other radiological indices, with a sensitivity of 84% and a specificity of 97% in successfully predicting redisplacement. We recommend it for routine use in the management of these fractures in children.

Introduction. To investigate if the gap index measured in the follow-up X-rays predicts the reduction of swelling in the plaster cast thereby increasing the risk of re-displacement of fracture treated by manipulation alone. Materials/Methods. We selected for this study a cohort of children who presented with a traumatic displaced fracture of distal radius at the junction of metaphysis and diaphysis who were treated with manipulation alone. This cohort was chosen because of the high risk of re-displacement following closed manipulation of this unstable fracture and to maintain uniformity of the fracture type. Cast index and Gap index was measured in the intra-operative radiograph and at two-weeks to note the change in these indices. Gap index which is measured by summing radial and ulnar translation/inner diameter of cast in the AP X-ray and similar translation on the lateral x-ray/inner diameter of cast, with a measure of <0.15 considered to be a satisfactory cast. Results. Forty-one children with a mean age of 9 years (mode-8, range 4–15 yrs) admitted between Jan 2008 and Feb 2010 with the above described fracture and were treated with manipulation alone were included in this study. Serial radiographs show a gradual loss of reduction in 34 (83%) children and 17 (41%) of these children required re-manipulation. As the plaster cast was not changed the cast index remained same while the gap index increased in the follow-up x-rays as the swelling subsided. In those children whose reduction remained satisfactory, the initial gap index was 0.14 which changed to 0.18 (n=7, p>0.05) while in children in whom the fracture lost reduction, the initial gap index was 0.18 and changed to 0.25 (n=34, p=0.0092) at two weeks. Conclusion. Gap index can easily be calculated on follow-up radiographs and can be used to assess the adequacy of plaster cast. From this study we can conclude that it is effective in assessing the adequacy of plaster cast as the swelling subsides

The February 2013 Children’s orthopaedics Roundup. 360 . looks at: ABC treated with suction and curettage; peri-acetabular osteotomy; cast index; Perthes’ disease associated with accidental injury; brachial plexus birth palsy; MRI assessment of DDH; total meniscectomy; and paediatric septic arthritis

The October 2012 Children’s orthopaedics Roundup³⁶⁰ looks at: magnetic growing rods and scoliosis correction; maintaining alignment after manipulation of a radial shaft fracture; Glaswegian children and swellings of obscure origin; long-term outcome of femoral derotation osteotomy in cerebral palsy; lower-leg fractures and compartment syndrome in children; fractures of the radial neck in children; management of the paediatric Monteggia fracture; and missing the dislocated hip in Western Australia.

Aim. Up to 34% of fractures of the distal radius in children can ‘re-displace’ early after reduction. Main risk factors are initial displacement (bayonet apposition, > 50% translation, and > 30°angulation), isolated distal radius fracture, associated ulna fracture at the same level, inadequate initial closed reduction and poor casting technique. This study was to identify the rate of ‘re-displacement’ following first successful reduction in distal radius fractures. We also assessed the risk factors associated with initial injury and compared the efficacy of the available indices to assess the quality of casting. Materials & Methods. We performed a case note based radiographic analysis of 90 distal radius fractures treated at our centre from 2005 to 2008. A cohort of 18 patients with re-displacement was compared with 72 patients with maintenance of reduction. Radiological indices were calculated to assess the quality of casting technique. The patient and fracture demographics were compared between the two groups. Statistical analysis was carried out using ANOVA, Fisher's Exact Test and multiple logistic regression analysis. Results. The rate of ‘re-displacement’ in our study was 20 %. A desirable cast index of < 0.7 was achieved in 4 out of 55 cases treated with cast alone. A significant difference (p< 0.008) was observed in the Three Point Index, the degree of comminution (< 0.01) and the quality of the initial reduction (< 0.003). Conclusion. We recommend careful identification of high risk factors and appropriate stabilisation for potentially unstable fractures at first treatment. The magnitude of initial deformity, the comminution, and the amount of remaining skeletal growth must all be considered in the decision making process. Further training to improve the quality of casting technique cannot be over-emphasised. Trainees should be trained to calculate the Three Point Index before accepting the reduction after casting to prevent late displacement and second anaesthesia

Introduction and aims. Cast immobilisation of paediatric forearm fractures has traditionally used plaster of Paris. Recently, synthetic casting materials have been used. There have been no studies comparing the efficacy of these two materials. The aim of this study is to investigate whether one material is superior for paediatric forearm fracture management. Methods. A single-centre prospective randomised trial of patients presenting to the Women's and Children's Hospital with acute fractures of the radius and/or ulna was undertaken. Patients were enrolled into the study on presentation to the Emergency Department and randomised by sealed envelope into either a fiberglass or plaster of Paris group. Patients then proceeded to a standardised method of closed reduction and cast immobilisation. Clinical follow-up occurred at one and six weeks post-immobilisation. A patient satisfaction questionnaire was completed following cast removal at six weeks. All clinical complications were recorded and cast indexes were calculated. Results. Initially 50 patients were recruited to the study, with equal randomisation. There were no significant differences between the patient demographics of the two groups. The results from this sample indicated an increase in clinical complications involving the plaster of Paris casting group. These complications included soft areas of plaster requiring revision, loss of reduction with some requiring re-manipulation and a high rate of cast spliting due to material swelling. The fractures that loss reduction had increased cast indices. Fibreglass casts were also preferred by patient and their families, with many observational comments regarding the light-weight and durable nature of the material. Conclusions. Cast immobilisation of paediatric forearm fractures is a common orthopaedic treatment. There is currently no evidence regarding the best material for casting. This study suggests that both clinical outcomes and patient satisfaction are superior with fiberglass casts, we are continuing this study to enable greater power with our results

Introduction. Displaced distal radius fractures in children have been treated in above elbow plaster casts since the last century. Cast index has been calculated previously, which is a measure of the sagittal cast width divided by the coronal cast width measurement at the fracture site. This indicates how well the cast was moulded to the contours of the forearm. We retrospectively analysed the cast index in post manipulation radiographs to evaluate its relevance in redisplacement or reangulation of distal forearm fractures. Study Design. Consecutive radiographic analysis. Materials and methods. 156 consecutive paediatric patients (114M : 42F), with a mean age of 9.8 years (range 2-15 years), presenting with forearm fractures were studied. All patients were manipulated in OR and a moulded above elbow cast was applied. The cast index was measured on immediate post manipulation radiographs. Results. Displacement of the fracture within the original plaster cast occurred in 30 patients (19%), 22/114 males; 8/42 females. The cast index in the 30 patients requiring a second procedure (mean 0.92, SD=0.08) was significantly more than the cast index (mean 0.77, SD=0.07) in the others (p< .001). Discussion. A high cast index in post manipulation radiographs indicates increased risk of re-displacement of the fracture and these patients should be kept under close review. Conclusion. Cast index is a valuable tool to assess the quality of moulding of the cast following closed manipulation of distal radius fractures in children. The maximum acceptable cast index should be 0.82

We present an objective method for predicting the redisplacement of paediatric forearm and wrist fractures. Novel radiographic measurements were defined and their value assessed for clinical decision making. In Phase I of the study we defined the cast index and padding index and correlated these measurements with the incidence of fracture redisplacement. Phase II assessed these indices for their value in clinical decision making. Cast Index (a/b) is the ratio of cast width in lateral view (a) and the width of the cast in AP view (b). Padding Index (x/y) isthe ratio of padding thickness in the plane of maximum deformity correction (x) and the greatest interosseous distance (y) in AP view. The sum of cast index and padding index was defined as the Canterbury Index. In Phase I, 142 children's radiographs were analysed and a statistically significant difference was identified between redisplacement and initial complete off-ending of the bones, cast index > 0.8 and padding index of > 0.3. There was no significant association with age, fracture location, seniority of surgeon or angulation. In Phase II, radiographs of 5 randomly selected cases were presented to 40 surgeons (20 consultants & 20 registrars). Following an eyeball assessment they were asked to measure the cast index and padding index (after instruction). With eyeballing the consultants predicted 33% and registrars 25% of the cases that redisplaced. After learning to measure the indices the accuracy increased to 72% for consultants and 81% for registrars (p<0.001). We conclude that the cast index, padding index and Canterbury Index are validated tools to assess plaster cast quality and can be used to predict redisplacement of paediatric forearm fractures after manipulation. They can easily be taught to orthopaedic surgeons and are more accurate than eyeballing radiographs in the clinical setting. Redisplacement can be predicted if cast index > 0.8, padding index > 0.3 and Canterbury Index > 1.1

Introduction: Traditionally Short arm plaster casts have been used to treat distal radius fractures. Judging adequacy of immobilisation has never been defined. A significant proportion of these fractures loose reduction due to inadequate immobilisation. A new non-invasive external fixator technology has been introduced to address the shortcomings of plaster casts. Aim: Is the new non invasive fixator better at reducing skin device interface movement, than conventional plasters. Materials and Methods: A prospective healthy volunteer study involving application of Short arm plaster of Paris cast, fibreglass cast and a new device Cambfix non-invasive wrist fixator with 15 forearms in each group, was undertaken. IRB approval and informed consent obtained from the volunteers. Colle’s type cast configuration was used. Displacement at the skin-cast and skin-new device interface was measured at proximal and distal ends. Maximal displacements noted immediately after application and after a specified intervals. Casts were windowed at the end of experiment and Cast index and Gap index were measured as ratios at the time of removal of casts. Statistical analysis was done using T-test and SPSS. Results: The non-invasive Cambfix fixator showed less mean displacement at both the proximal and distal parts compared to plaster and fibreglass casts (p< 0.01). The mean gap index for the Cambfix device was 0.09, which was statistically significantly less than 0.15 and 0.14 for Plaster of Paris and fibreglass casts respectively (p< 0.01). Casts with higher gap index showed increased displacement, however cast index was less predictive of skin-cast displacement. Conclusions: Skin-device interface movement was significantly better reduced with the Cambfix non-invasive fixator as compared with Short arm plaster of Paris and fibreglass casts. Lesser gap index is known to provide less interface movement. The Cambfix non-invasive fixator appears to achieve a better gap index more consistently. Limitations include healthy volunteer group, and relatively small numbers

Introduction: We aimed to assess a simple radiological method of predicting redisplacement of paediatric forearm fractures. The Cast Index (CI) is the ratio of sagittal to coronal width from the inside edges of the cast at the fracture site. A CI of > 0.7 was used as the standard in predicting fracture redisplacement. The cast index has previously been validated in an experimental study. Methods: Case records and radiographs of 1001 children who underwent a manipulation under general anaesthesia for a displaced fracture of the distal forearm were studied. Redisplacement was defined as more than 15 degrees of angulation and/or more than 80 percent of translational displacement on check radiographs at 2 weeks. Angulation (in degrees) and translation displacement (in percentage) were measured on the initial and check radiographs. The CI was measured on postoperative radiographs. Results: Fracture redisplacement was seen in 107 cases at 2 week follow up. Of the 752 patients (75%) with a CI of less than 0.7 the displacement rate was 5.58%. Of the 249 patients (25%) with a CI greater than 0.7 the redisplacement rate was 26%. The CI was significantly higher in the redisplacement group. No statistically significant difference was seen for age, sex or ethnicity. Nor were statistical differences noted in initial angular deformity, initial displacement and seniority of the surgeon. Good intra and inter observer reproducibility was observed. There was no statistical difference in patients with a cast index between 0.7 and 0.8. Conclusion: The cast index is a simple and reliable radiographic measurement to predict the redisplacement of forearm fractures in children. Previous studies have used a CI of > 0.7 as the predictor of redisplacement although this study suggests a plaster with a CI of < 0.81 is acceptable. A high cast index is associated with redisplacement of fractures and should therefore be considered when moulding casts in distal forearm fractures

Purpose: Waterproof casts have been shown to be a safe and effective means of immobilization in children with minimally displaced fractures. The purpose of this study was to determine if waterproof Gore-Tex-lined casts are as effective as traditional cotton-lined casts in the immediate postoperative period after closed reduction of displaced distal radius fractures in children. Method: We performed a retrospective review of distal radius fractures that underwent closed reduction and application of a long-arm cast between June 2004 and December 2006. A total of 124 cases were included (55 Gore-Tex; 69 traditional cotton-lined). The primary outcome measure was redisplacement in the cast. The cast index was also used to assess the quality of cast molding. Data was analyzed using repeated measures ANOVA. Power analyses were also conducted. Results: There were no significant differences between the two groups with regards to translation of the radius or angulation of the radius on anterior-posterior (AP) and lateral radiographs at the time of injury, postreduction, or cast removal. Redisplacement as measured by the change in translation of the radius and angulation of the radius on AP and lateral radiographs from the time of reduction to cast removal was also not significantly different between the two groups. The mean cast index for the Gore-Tex and traditional cotton-lined groups was 0.882 and 0.873 respectively, which was not a significant difference. Conclusion: A waterproof Gore-Tex-lined cast will maintain fracture reduction as well as a cotton-lined cast for closed reductions of distal radius fractures in children in the immediate postreduction period. Waterproof casts also provide extensive benefits to the patient with regards to bathing, hygiene, and participation in aquatic activities

We aimed to assess a simple radiological method of predicting redisplacement of paediatric forearm fractures. The Cast Index (CI) is the ratio of sagittal to coronal width from the inside edges of the cast at the fracture site. CI of 0.7 was used as the benchmark in predicting fracture redisplacement. Case records and radiographs of 1001 children who underwent a manipulation under general anaesthesia for a displaced fracture of the distal forearm were studied. Redisplacement was defined as more than 15 degrees of angulation and/or more than 80 percent of translational displacement on check radiographs at 2 weeks. Angulation (in degrees) and translation displacement (in percentage) were measured on the initial and check radiographs. The Cast index was measured on the check radiographs. Good intra and inter observer reproducibility was observed for both these measurements. The cast index has been previously validated in an experimental study. The adequacy of reduction after manipulation was estimated by the postreduction translation and angulation of the radius and ulna in anteroposterior and lateral plain film radiographs. The 1001 patients who qualified for the study, fracture redisplacement was seen in 107 cases at the all important two week follow up. Seven hundred and fifty-two patients had cast indices of 0.8 or less whilst 249 had casting indices of 0.81 or more. In patients with cast indices of 0.8 or less, the displacement rate was only 5.58%. However, in patients with cast indices of 0.81 or more, the displacement rate was 26%. Initial displacement, angulation and the post manipulation cast index were the three factors which were significantly higher in the redisplacement group. No statistically significant difference was seen for age, sex or ethnicity. Nor were statistical differences noted in initial angular deformity, initial displacement and seniority of the surgeon. There was no statistical difference in patients with cast indices between 0.7 and 0.8. Cast index is a simple reliable radiographic measurement to predict the redisplacement of forearm fractures in children. A plaster with a CI of > 0.81 is prone to redisplacement. A high cast index is associated with redisplacement of fractures and should therefore be considered when moulding casts is distal forearm fractures

Aims:. 1) To determine the predictive value of a simple stability test in children’s wrist fractures treated with simple manipulation and plaster of Paris (PoP) cast immobilisation. 2) To determine the effect of cast quality as reflected in the skin cast distance (distance between the cast and the skin in the plane of major displacement or angulation) and the cast index (the inside diameter of the cast in the sagittal plane divided by the inside diameter in the coronal plane) on re-displacement rates in children’s wrist fractures treated with simple manipulation and plaster of Paris (PoP) cast immobilisation. Methods: This is a prospective study of 57 children aged 4 to 15 with metaphyseal and Salter-Harris II wrist fractures treated with simple manipulation. Under fluoroscopic imaging, a simple stability test involving moving the hand at the wrist in the dorsopalmar, and radioulnar planes was performed following reduction, and x-ray images were saved. We recorded and compared the displacement and angulation on the initial x-rays, during the test, and at one-and 6-week follow-up. We also recorded the skin-cast distance (SCD), and the cast index (CI). Results: 38 patients had isolated radius fractures and 19 had radius and ulna fractures. Four patients needed remanipulation with K-wire fixation. Multiple regression analysis revealed significant correlation between percentage loss of reduction on testing and subsequent re-displacement (relationship between the two sets of values r = 0.6167, (p< 0.001)). This indicates that instability on testing (seen as a significant percentage loss of reduction) is likely to be associated with some loss of reduction on follow-up. There was a significant relationship between the skin cast distance and the cast index, and loss of reduction on one week follow-up. (p=0.006). Isolated radius fractures had a higher risk of re-displacement than radius and ulna fractures (3.9% and 0.9% respectively; p< 0.05%). Conclusion: Stable reduction on stability testing in wrist fractures in children immobilised in a good cast (reflected in a low SCD, and CI) is associated with a good outcome. Isolated radius and ulna fractures are more likely to re-displace than radius and ulna fractures. There is a relationship between instability and loss of position at the 1-week follow-up. Potentially unstable fractures can be prevented from slipping by a good cast. A stable fracture on our stability test rarely slips. We therefore feel that stability test is a useful adjunct in decision-making

Background: The epidemiology of fracture in children has been reported in detail by other authors. The most common mechanism in their study was a fall in or around the house onto an outstretched hand causing a fracture of the distal radius and ulna. These injuries accounted for 35.8% of all fractures in this age group and the annual incidence was estimated to be 16 per 1000 children in the UK. The controversial issues in the management of distal radius fracture involve what constitutes a degree of fracture displacement and angulation likely to be compensated by remodelling with growth over time, indications for fracture stabilisation with wires or other invasive methods compared with plaster casting alone, details of the position of the arm during immobilisation in a cast, and whether the cast should immobilise the wrist alone or both, the wrist and the elbow. The management of buckle fractures of the distal radius is relatively uncontroversial, involving splintage for symptomatic relief from pain. Some authors have advocated removable wrist supports, with discontinuation of splintage at the parents’ discretion. We performed a systematic review of all areas of the management of distal radius metaphyseal fractures in children. Growth plate injuries were not included for analysis. Methods: Any randomised or quasi-randomised controlled trials which compared types of immobilisation and the use of wire fixation for distal radius fractures in children were included. Types of outcome measures:. Radiological deformity. Effect of cast index. Complications of k-wiring. Remanipulation rates. Compliance with splintage. Cost of various forms of splintage. Effect of intact ulna. Upper limb function while immobilised. Wrist and elbow ROM. 10 studies complied with the inclusion criteria and were analysed using Review Manager software provided by the Cochrane Collaboration. Summary of Results:. Regarding displaced metaphyseal fractures:. K wire fixation reduces redisplacement. There is no proven increase in complications with k wires. Intact ulna favours redisplacement. Long casts do not reduce displacement. Short casts allow better early function. Regarding stable compression fractures:. Removable splints are not associated with displacement. Patients prefer removable splints for buckle fractures. Removable splints cause less discomfort and allow better early function
