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

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

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.

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

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

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

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

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

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

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

Aim. With the current wave of enthusiasm for internal fixation with volar locking plates in the treatment of distal radial fractures, radiology of the wrist needs review. With current standardised x-rays of the wrist there is often an appearance of intra-articular screws. This is on account of the objective of getting very distal subchondral fixation and fixation into the radial styloid. As a consequence, due to the volar tilt and radial inclination of the ‘anatomic’ wrist, fixation is often perceived and reported to be intra-articular. It is proposed in this study that ‘standard’ wrist x-rays post-internal fixation be taken with 20° elbow flexion on the lateral view to counteract radial inclination. The postero-anterior view should be angled 10° to view the joint without the effect of normal radial tilt. Method and Materials. 30 consecutive wrists treated by fixed angled volar fixation were analysed. In each case standard x-rays and the proposed ‘20, 10’ radiographs were obtained. The ‘20, 10’ x-rays were taken with a custom-made set of bolsters set at 20° and 10° for the Lateral and PA views. Each set of x-rays (a standard PA and lateral and the so called ‘20, 10’ proposed radiographs) were commented on by 2 Radiologists and 2 Orthopaedic Surgeons. Results. It would appear that in both the Radiologists' and Orthopaedic surgeons' reports there was a higher degree of confidence in reporting on the 20, 10 views than on the standard views. In just over 50% of cases standard views had the appearance of intra-articular fixation while this perception was disproven with the newly proposed 20, 10 views. The correlation between Radiologist and Orthopaedic Surgeon reports was almost 100%. Conclusion. With the current trend to volar wrist fixation we should adapt our radiology protocols. We propose 20, 10 angled x-rays as standard for post-operative wrist radiology

The Royal Marines regularly deploy to Norway to conduct Cold Weather, Arctic and Mountain Warfare training. A total of 1200 personnel deployed to Norway in 2010 over a 14-week period. Patients, whose injuries prevented them from continuing training, were returned to the UK via AEROMED. The aim of this investigation was to describe the epidemiology of musculoskeletal injuries during cold weather training. All data on personnel returned to the UK was prospectively collected and basic epidemiology recorded. 53 patients (incidence 44/1,000 personnel) were returned to the UK via AEROMED. 20/53 (38%) of cases were musculoskeletal injuries (incidence 17/1000 personnel). 15/20 musculoskeletal injuries were sustained while conducting ski training (incidence 13/1,000): 4/20 were non-alcohol related injuries, 1/20 was related to alcohol consumption off duty. Injuries sustained whilst skiing: 5/15 sustained anterior shoulders dislocation, 5/15 Grade 1-3 MCL/LCL tears, 2/15 sustained ACJ injuries, 1/15 crush fracture T11/T12, 1/15 tibial plateau fracture and 1/15 significant ankle sprain. Non-Training injuries: 1 anterior shoulder dislocation, 1 distal radial fracture, 1 olecranon fracture, 1 Scaphoid Fracture and one 5th metatarsal fracture. 60% of injuries were upper limb injuries. The most common injury was anterior shoulder dislocation 6/20 (Incidence 5/1000). Our results suggest that cold weather warfare training has a high injury rate requiring evacuation: 4% of all people deployed will require AEROMED evacuation, and 2% have musculoskeletal injuries. Ski training causes the majority of injuries, possibly due to the rapid transition from non-skier to skiing with a bergen and weapon. Military Orthopaedic and rehabilitation units supporting the Royal Marines, should expect sudden increases in referrals when large scale cold weather warfare training is being conducted. Further research is required to see if musculoskeletal injury rates can be decreased in cold weather warfare training

Aims

In the UK, the NHS generates an estimated 25 megatonnes of carbon dioxide equivalents (4% to 5% of the nation’s total carbon emissions) and produces over 500,000 tonnes of waste annually. There is limited evidence demonstrating the principles of sustainability and its benefits within orthopaedic surgery. The primary aim of this study was to analyze the environmental impact of orthopaedic surgery and the environmentally sustainable initiatives undertaken to address this. The secondary aim of this study was to describe the barriers to making sustainable changes within orthopaedic surgery.

Distal radial volar locking plating systems (DRVLP) are increasingly used for complex fractures of the distal radius. There have been limited studies on volar locking plating systems focusing on functional outcome and complications data. The aim of this study is to assess whether the surgeon can predict which fractures will have a good or poor outcome in terms of clinical, radiological and functional outcome assessment. Patients who sustained a distal radial fracture managed with a radial volar locking plate were identified from hospital audit data systems. Data was collected on all patients from patient notes including radiographs performed pre- and post-operatively and functional scores using the Patient Rated Wrist Evaluation score (PRWE). The study was approved by the Barwon Health Research and Ethics Advisory Committee. In total, there were 153 patients (105 female, 48 male) from all 11 surgeons in the unit. Patients ranged in age from 17 to 91 years, average age of 53.7 years at time of injury (IQR 41-70yr). A quarter had concomitant other injuries, and 60% had type C1-C3 fractures. Most of the patients (n = 147) had the AO Synthes DRVLP, six patients had other volar locking plate systems. Twenty-seven percent of patients (n = 42) had exogenous bone graft insertion for more unstable fracture patterns. The major complication rate was 12% (18/153) with 17 cases requiring further surgery. Post-operative radiographs demonstrated no increase in ulnar variance (median 0.0mm IQR 2.0 to1.0 mm) but an increase in radial inclination by 5 deg (IQR 0-12 deg), radial length by 3.5 mm (IQR 1.0-6.3 mm) and radial tilt by 17 deg (IQR 3-32 deg) (volar angulation) compared to pre-operative radiographs, which was statistically significant (all p<0.001). Ninety percent of patients returned a PRWE form with an average follow-up of 1.16 years (IQR 0.46-2.16yr). Median score for those aged less than 50 years was 14.00 (IQR 6.00-41.50) and did not differ from those greater than 50 years (median 16.00 IQR 4.50-36.00) (p = 1.00). PRWE score across groups categorised by classification of fracture showed large variance within each category and were not significantly different: Class A median 8.00 (IQR 3.50-26.25), Class B 13.00 (IQR 6.75-34.00) and Class C 17 (IQR 5.00-38.50) (p = 0.65). The majority of patients were female and had a type C fracture. Post-operative x-rays displayed an increase in radial inclination, length and tilt, and restoration of radial antatomy. PRWE scores were not different across age groups or classification of the fracture. This demonstrates that predictable outcomes can be achieved with volar locking plates despite fracture complexity if attention is paid to anatomical restoration of the radius, and in more unstable patterns with void support using injectable graft. Quadratus can act as an effective barrier to prominent hardware and superficial infection. Supination range may be reduced by this approach due to a tight repair, though a palmar DRUJ capsule contracture may also be an explanation

Purpose. To determine, in skeletally immature children with acceptably angulated (< = 15 degrees deformity at presentation) distal radius fractures, if a pre-fabricated wrist splint is at least as effective as a cast. Methods. A randomised controlled, non-inferiority, single blinded, single-centre trial was performed. The primary outcome was physical function at six weeks. Secondary outcomes included angulation, wrist range of motion, strength, pain, and patient preferences. Results. 93 of 97 randomised patients completed full follow-up. ASK scores at six weeks were 92.8 in the splint group and 91.4 in the cast group. Among patients treated in a cast, the average angular deformity at follow-up was 11.0 degrees, compared with an average of 6.6 degrees angulation among patients treated in a splint (p=0.02, t-test). Complications did not differ between groups, nor did range of motion. Conclusion. Splinting was not inferior to casting, and in fact may be superior to casting, for maintaining the position of a minimally displaced distal radial metaphyseal fracture. Significance. The benefits of splinting over casting have been previously established for undisplaced distal radius and ulnar fractures (Plint), this is the first study which extends the benefits of splinting to the large group of children with minimally displaced distal radius fractures

Fresh-frozen allograft bone is frequently used in orthopaedic surgery. We investigated the incidence of allograft-related infection and analysed the outcomes of recipients of bacterial culture-positive allografts from our single-institute bone bank during bone transplantation. The fresh-frozen allografts were harvested in a strict sterile environment during total joint arthroplasty surgery and immediately stored in a freezer at -78º to -68º C after packing. Between January 2007 and December 2012, 2024 patients received 2083 allografts with a minimum of 12 months of follow-up. The overall allograft-associated infection rate was 1.2% (24/2024). Swab cultures of 2083 allografts taken before implantation revealed 21 (1.0%) positive findings. The 21 recipients were given various antibiotics at the individual orthopaedic surgeon’s discretion. At the latest follow-up, none of these 21 recipients displayed clinical signs of infection following treatment. Based on these findings, we conclude that an incidental positive culture finding for allografts does not correlate with subsequent surgical site infection. Additional prolonged post-operative antibiotic therapy may not be necessary for recipients of fresh-frozen bone allograft with positive culture findings.
