The aim of operative treatment for ankle fractures is to allow early movement after internal fixation. The hypothesis of this study was that early mobilisation facilitated by a removable cast after internal fixation of ankle fractures would improve functional recovery of patients compared with that after conventional immobilisation in a cast. Sixty-two patients between the age of seventeen and sixty-five with ankle fractures that required operative treatment were randomly allocated to two groups: immobilisation in a non weight bearing below knee cast for six weeks or early movement in a removable cast (at two weeks after removal of sutures) for the following four weeks. The follow-up examinations which consisted of subjective (clinical, Olerud-Molander score, AOFAS score, SF 36) and objective (swelling measurement, x-ray) evaluations were performed at two, six, nine, twelve and twenty four weeks post-operatively. Time of return to work was recorded. There were two post-operative complications in the group treated with immobilisation in cast; two patients had deep vein thrombosis (DVT). There was one superficial wound infection treated with oral antibiotics and two deep wound infections requiring removal of metal in the group treated with early movement in a removable cast. Patients in group two (early movement) had higher functional scores at nine and twelve weeks follow-up. They also returned to work earlier (63.7 days) compared with the ones treated in cast (94.9 days). There was no statistical difference in Quality of Life (SF-36 Questionnaire) at six months between the two groups. Early movement with the use of removable cast after removal of sutures in operated ankle fractures decreases swelling, prevents calf muscle wasting, improves functional outcome and facilitates early return to work of patients. Our findings support the use of a removable cast and early exercises in selected, compliant patients after surgery of the ankle

Introduction. A subset of patients in cast awaiting fixation of ankle fractures require conversion to delayed external fixation (dEF). We aimed to evaluate the effect of delayed versus planned external fixation (pEF), then identify objective characteristics contributing to need for conversion. Method. We extracted data from our booking system to identify all ankle external fixation procedures between 2010 to 2022. Exclusions included open fractures, the skeletally immature, and pilon or talus fractures. Fractures were classified using the AO/OTA classification, then a matched cohort was identified based on fracture classification. We compared the planned, delayed and matched cohorts for demographics, posterior malleolar fragment (PMF) ratio, and degree of displacement at presentation. Results. We identified 25 pEF, 42 dEF, and 67 matched patients. Ankles with dEF had a 3.8 day longer time to ORIF from presentation than those who had pEF, and had an infection rate of 9.5%, compared to 4% in the pEF group. Two patients in the dEF group required further operative intervention. There were no infections or reoperations required in the pEF or matched groups. The dEF group were more likely to have ≥2 reductions (OR 4.13), a PMF ratio of >0.23 (OR 5.07), and have increased displacement at time of injury on lateral (32% vs 19%) and AP (62% vs 36%) radiographs. Discussion. Our retrospective study highlights the longer time to operation and increased infection rates of patients who do not get timely external fixation. We propose a series of objective parameters that predict failure of cast treatment and guide the surgeon to consider planned external fixation in some ankle

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

Orthopaedic surgeons frequently assess fragility fractures (FF), however osteoporosis (OP) is often managed by primary care physicians (PCP). Up to 48% of FF patients have had a previous fracture (Kanis et al., 2004). Discontinuity between fracture care and OP management is a missed opportunity to reduce repeat fractures. This studied aimed to evaluate current OP management in FF patients presenting to cast clinic. A single centre, prospective observational study where seven traumatologists screened for FF in cast clinic. FF was defined as a hip, distal radius (DR), proximal humerus (PH), or ankle fracture due to a ground level fall. Patients completed a self-administered questionnaire for demographics, fracture type and treatment, medical and fracture history, and previous OP care. The primary outcome was number of FF patients who received OP investigation and/or treatment. Secondary outcomes included Fracture Risk Assessment Tool (FRAX), repeat fracture rate, and anti-resorptive related fractures. Descriptive statistics were used for analysis. Between November 17, 2014 and October 13, 2015, a total of 1,677 patients attended cast clinic for an initial assessment. FF were identified in 120 patients (7.2%). The FF cohort had a mean age of 65.3 (± 14.3) years, mean BMI of 26.1 (± 5.3), and was comprised of 83.3% females. Fracture distribution was 69 (57.5%) DR, 23 (19%) ankle, 20 (16.5%) PH, and seven (5.8%) hip fractures, with 24 of the FF (19.8%) treated operatively. Thirteen (10.8%) were current smokers and 40 (33.3%) formerly smoked. A history of steroid use was present in 13 patients (10.8%). Ninety (n = 117; 76.9%) of patients ambulated independently. Twenty-two patients (18.3%) reported prior diagnosis of OP, most often by a PCP (n = 19; 73.7%) over 5 years previously. Calcium (n = 59; 49.2%) and Vitamin D (n = 70; 58.3%) were common and 26 patients (21.5%) had a prior anti-resorptive therapy, with Alendronate (n = 9) being most common. One patient had an anti-resorptive-related fracture. Raloxifene was used in ten patients. Forty-seven patients (39.2%) had a prior fracture at a mean age of 61.3 (± 11.9) years, with DR and PH fractures being most common. Eleven patients had two or more prior fractures. A family history of OP was found in 34 patients (28.1%). Mean FRAX score was 20.8% (± 10.8%) 10-year major fracture risk and 5.9% (± 6.6%) 10-year hip fracture risk (n = 30 bone densiometry within one-year). Of the 26 patients with a Moderate (10–20%) or High (> 20%) 10-year major fracture risk, only eight (30.8%) reported a diagnosis of OP and only three (11.5%) had seen an OP specialist. Cast clinics provide an opportunity for OP screening, initiation of treatment, and patient education. This cohort demonstrated a high rate of repeat fractures and poor patient reporting of prior OP diagnosis. This study likely underestimated FF and calls for resource allocation for quantifying true burden of disease and outpatient fracture liaison service

Femoral shaft fractures are fairly common injuries in paediatric age group. The treatment protocols are clear in patients of age less than 4 years and greater than 6 years. The real dilemma lies in the age group of 4–6 years. The aim of this study is to find whether a conservative line should be followed, or a more aggressive surgical intervention can provide significantly better results in these injuries. This study was conducted in a tertiary care hospital in Bhubaneswar, India from January 2020 to March 2021. A total of 40 patients with femur shaft fractures were included and randomly divided in two treatment groups. Group A were treated with a TENS nail while group B were treated with skin traction followed by spica cast. They were regularly followed up with clinical and radiological examination to look out for signs of healing and any complications. TENS was removed at 4–9 months’ time in all Group A patients. Group A patients had a statistically significant less hospital stay, immobilisation period, time to full weight bearing and radiological union. Rotational malunions were significantly lower in Group A (p-value 0.0379) while there was no statistically significant difference in angular malunion in coronal and sagittal plane at final follow up. Complications unique to group A were skin necrosis and infection. We conclude that TENS is better modality for treatment of shaft of femur fractures in patients of 4–6 years age as they significantly reduce the hospital stay, immobilization period and rotational malalignment

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

Aim. To demonstrate the effect of location of the split of the plaster on the raised intercompartmental pressure in the volar and dorsal compartments. Methods. Artificial forearm skeleton was used along with two half litre saline bags on ether side representing volar and dorsal forearm compartment. A single layer of cotton wool with half width overlap was applied followed by three rolls of 10cm x 2.5 m plaster of paris. This was then left to dry for four hours. Both the saline bags had an eighteen gauge catheter inserted that was connected to the central venous pressure monitoring line on the anaesthetic machine. Baseline pressure in mmHg was recorded. Normal saline was then injected in both the bags so as to raise the pressure to 50 mmHg in each compartment. POP cast was then split, spread and then the wool was cut down to the saline bags while continually monitoring the pressures. The respective change in the pressure at the end of each step was recorded. Six simulated forearm models had dorsal splits and an equal number had volar splits. The effect of the site and various steps of splitting on the drop in respective compartment pressures was compared. Results. The mean drop in pressure was 24mmHg after all the steps of splitting were completed. This was independent of the site of the split of the cast. The mean drop in ICP after spreading the cast was statistically significant (P=0.01) when compared to cutting cast and cutting wool. Conclusions. Split in cast has similar effect on both, same side and opposite side, compartments in reducing the ICP. Spreading of the cast is the most effective step in reducing the raised ICP and should not be missed

Patients who have an injured limb treated in a cast may need to travel on an aircraft. The Civil Aviation Authority (CAA) have issued guidelines to help clinicians and airline companies decide if patients are safe to travel on an aircraft, or if they need to have the cast altered. Patients may seek advice from the airline companies without consulting their clinicians. This study looked at the published advice on the websites of commercial airline companies, and requested written guidelines from those with whom no published advice was available. Out of the top 16 companies flying in and out of the UK, only six followed the CAA advice, seven did not have a clear policy, and some offered advice that could be worrying to some clinicians. This study shows that there is little evidence available to help airline companies and clinicians decide if it is un-safe to allow people to fly with a cast. The advice from airlines is conflicting and confusing for patients, therefore a more consistent approach may be needed to allow safe air travel, to avoid inappropriate alterations of casts and to avoid unnecessary visits to the fracture clinic

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

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

Instances of skin burns whilst splitting orthopaedic casts using oscillating plaster saws have been reported. Previous work has found contact temperatures over 65°C to burn skin within a second. We compared saw blade temperatures generated whilst splitting casts using two blades, two cutting techniques, with and without a dust extraction vacuum. Gypsona (Smith & Nephew Healthcare), Scotchcast Poly, Scotchcast Softcast and Scotchcast Plus Fibreglass (3M Healthcare) casts were formed by applying casting material to PVC pipe over cast padding and stockingette. Casts were left for one week to dry and then split using an all-purpose cast saw blade and a mortuary saw blade (de Soutter) fitted to a CleanCast CC5 oscillating saw (de Soutter). This saw has an inbuilt vacuum dust extraction system; casts were split with this system turned on and off, using the standard ‘up-down’ technique and a dragging technique. Blade temperatures were recorded during splitting using a digital thermometer (DS18B20, Dallas Semiconductors) fixed to the blade. Average maximum blade temperatures from five cuts were calculated and statistical analysis conducted. Splitting synthetic casts with an ‘up-down’ technique generated higher temperatures than splitting gypsona (softcast +5.5°C p=0.06, fibreglass +9.0°C p=0.03, polyester +20.0°C p<0.001). Mortuary blades generated similar temperatures to cast saw blades except whilst splitting fibreglass (+5.6°C p=0.031). Compared to the ‘up-down’ technique, the ‘dragging’ technique generated higher blade temperatures irrespective of material (gypsona +10.7°C p=0.005, softcast +7.1°C p=0.001, fibreglass +16.6°C p=0.001, polyester +11.4°C p=0.001). The vacuum dust extraction system reduced temperature irrespective of material being split (gypsona -12.4°C p=0.002, softcast - 20.7°C p<0.001, fibreglass -19.2°C p=0.001, polyester -29.1 p<0.001). Blade temperatures whilst splitting synthetic casts were significantly higher than whilst splitting gypsona. The vacuum dust extraction system cooled blades to a temperature at which thermal skin burns cannot occur

Most of current literatures advise on thromboprophylaxis with injectable LMWH for trauma patients. Injectable anticoagulants have got inherent problems of pain, bruising and difficulty in administering the drug, which leads to low compliance. Clexane is derived from a pig's intestinal mucosa, hence could be objectionable to certain proportion of patients because of their religious beliefs. Oral anticoagulants have been used as thromboprophylactic agents in hip and knee arthroplasty. However there is not enough literature supporting their use as thromboprophylactic agent in ambulatory trauma patients with ankle fracture being managed non-operatively as out-patient. This study looks into the efficacy of oral anticoagulant in preventing VTE in ambulatory trauma patients requiring temporary lower limb immobilisation for management of ankle fracture. The end point of this study was symptomatic deep vein thrombosis (either proximal or distal) and pulmonary embolism. Routine assessment with a VTE assessment risk proforma for all patients with temporary lower limb immobilisation following lower limb injury requiring plaster cast is done in the fracture clinic at this university hospital. These patients are categorised as low or high risk for a venous thromboembolic event depending on their risk factor and accordingly started on prophylactic dose of oral anticoagulant (Rivaroxaban - Factor Xa inhibitor). Before the therapy is started these patients have a routing blood check, which includes a full blood count and urea and electrolyte. Therapy is continued for the duration of immobilisation. Bleeding risk assessment is done using a proforma based on NICE guideline CG92. If there is any concern specialist haematologist advice is sought. A total of 200 consecutive patients who presented to the fracture clinic with ankle fracture, which was managed in plaster cast non-operatively, were included in this study. They were followed up for three months following injury. This was done by checking these patients’ radiology report including ultrasound and CT pulmonary scan (CTPA) test on hospital's electronic system. Fracture of the lateral malleolus which include Weber-A, Weber-B and Weber-C fractures were included in the study. Also included were bimalleolar fractures and isolated medial malleolus fractures. Complex pilon fractures, polytrauma and paediatric patients were excluded from the study. Only one case of plaster associated isolated distal deep vein (soleal vein) thrombosis was reported in this patient subgroup. There was no incidence of proximal deep vein thrombosis or pulmonary embolism. No significant bleeding event was reported. Injectable low molecular weight heparin (LMWH) rather than oral anticoagulant has been recommended by most of the studies and guidelines as main thromboprophylactic agent for lower limb trauma patients

The Ponseti method is the gold standard treatment for clubfoot. It begins in early infancy with weekly serial casting for up to 3 months. Globally, a commonly reported barrier to accessing clubfoot treatment is increased distance patients must travel for intervention. This study aims to evaluate the impact of the distance traveled by families to the hospital on the treatment course and outcomes for idiopathic clubfoot. No prior studies in Canada have examined this potential barrier. This is a retrospective cohort study of patients managed at a single urban tertiary care center for idiopathic clubfoot deformity. All patients were enrolled in the Pediatric Clubfoot Research Registry between 2003 and April 2021. Inclusion criteria consisted of patients presenting at after percutaneous Achilles tenotomy. Postal codes were used to determine distance from patients’ home address to the hospital. Patients were divided into three groups based on distance traveled to hospital: those living within the city, within the Greater Metro Area (GMA) and outside of the GMA (non-GMA). The primary outcome evaluated was occurrence of deformity relapse and secondary outcomes included need for surgery, treatment interruptions/missed appointments, and complications with bracing or casting. A total of 320 patients met inclusion criteria. Of these, 32.8% lived in the city, 41% in the GMA and 26% outside of the GMA. The average travel distance to the treatment centre in each group was 13.3km, 49.5km and 264km, respectively. Over 22% of patients travelled over 100km, with the furthest patient travelling 831km. The average age of presentation was 0.91 months for patients living in the city, 1.15 months for those within the GMA and 1.33 months for patients outside of the GMA. The mean number of total casts applied was similar with 7.1, 7.8 and 7.3 casts in the city, GMA and non-GMA groups, respectively. At least one two or more-week gap was identified between serial casting appointments in 49% of patients outside the GMA, compared to 27% (GMA) and 24% (city). Relapse occurred in at least one foot in 40% of non-GMA patients, versus 27% (GMA) and 24% (city), with a mean age at first relapse of 50.3 months in non-GMA patients, 42.4 months in GMA and 35.7 months in city-dwelling patients. 12% of the non-GMA group, 6.8% of the GMA group and 5.7% of the city group underwent surgery, with a mean age at time of initial surgery of 79 months, 67 months and 76 months, respectively. Complications, such as pressure sores, casts slips and soiled casts, occurred in 35% (non-GMA), 32% (GMA) and 24% (city) of patients. These findings suggest that greater travel distance for clubfoot management is associated with more missed appointments, increased risk of relapse and treatment complications. Distance to a treatment center is a modifiable barrier. Improving access to clubfoot care by establishing clinics in more remote communities may improve clinical outcomes and significantly decrease the burdens of travel on patients and families

Aim. The aim of this paper is to analyse the cause of neuropathic diabetic foot ulcers and discuss their preventive measures. Methods. Review of patients with foot ulcers managed in our diabetic MDT clinics since Feb 2018 were analysed. Based on this observation and review of pertinent literature, following observations were made. Results. Forefoot. Progressive hindfoot equinus from contraction of gastroc-soleus-tendo-Achilles complex, with additional contraction of tibialis posterior and peroneal longus muscles and, progressive plantar flexed metatarsal heads secondary to claw toe deformity results in increased forefoot plantar pressures. In patients with insensate feet, this result in ulcer formation under the metatarsal heads from shear stress when walking. Callosity under the metatarsal heads is the earliest clinical sign. Most patients by this time have fixed tightness of the muscle groups as assessed by negative Silfverskiold test. Percutaneous tendo-Achilles lengthening (TAL) has shown to reduce the mid-forefoot plantar pressures by 32% and ulcer healing in 96% of patients within 10 weeks (± 4 weeks). Additional z-lengthening of peroneal longus and tibialis posterior tendons helped in patients with big-toe and 5. th. metatarsal head ulcers. Proximal metatarsal osteotomies further reduce the forefoot pressures to near normality. Midfoot. Midfoot ulcers are secondary to rocker-bottom deformity a consequence of Charcot neuroarthropathy (CN). Hindfoot equinus as described and relative osteopenia from neurally mediated increased blood flow (neurovascular theory) and repeated micro-trauma (neurotraumatic theory) result in failure of medial column osseo-ligamentous structures. As the disease progress to the lateral column, the cuboid height drops resulting in a progressive rocker bottom deformity. The skin under this deformity gradually breaks down to ulceration. In the pre-ulcerative stages of midfoot CN, TAL has shown to stabilise the disease progression and in some patents’ regression of the disease process was noted. The lump can excised electively and the foot accommodated in surgical shoes. Hindfoot. These develop commonly at the pressure areas and bony exostosis in non-ambulatory patients. In ambulatory patients, the most common cause are factors that result in over lengthening of tendo-Achilles such as after TAL, spontaneous tears, or tongue-type fractures. Conclusions. Early identification of factors that result in plantar skin callosity and treating the deforming forces prevent progression to ulceration. Total contact cast without treatment of these deforming forces results in progression of these callosities to ulceration while in the cast or soon after completion of cast treatment

The purpose of this study was to investigate the effectiveness of casting in achieving acceptable radiological parameters for unstable ankle injuries. This retrospective observational cohort study was conducted involving the retrieval of X-rays of all ankles taken over a 2 year period in an urban setting to investigate the radiological outcomes of cast management for unstable ankle fractures using four acceptable parameters measured on a single X- ray at union. The Picture Archiving and Communication System (PACS) was used, the X-rays were measured by a single observer. From the 1st of January 2020 to the 31st of December 2021, a total of 1043 ankle fractures were treated at the three hospitals with a male to female ratio of 1:1.7. Of the 628 unstable ankle injuries, 19% of patients were lost to follow up. 190 were managed conservatively with casts, requiring an average of 4 manipulations, with a malunion rate of 23.2%. Unstable ankle injuries that were treated surgically from the outset and those who failed conservative management and subsequently converted to surgery had a malunion rate of 8.1% and 11.0% respectively. Unstable ankle fractures pose a challenge with a high rate of radiological malunion, regardless of the treatment Casting surgery from the outset or converted to surgery, with rates of 23% and 8% and 11% respectively. In this multivariate analysis we found that conservative management was the only factor influencing the incidence of malunion, age, sex and type of fracture did not have a scientific significant influence

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

Aims. To determine the impact of COVID-19 on orthopaediatric admissions and fracture clinics within a regional integrated care system (ICS). Methods. A retrospective review was performed for all paediatric orthopaedic patients admitted across the region during the recent lockdown period (24 March 2020 to 10 May 2020) and the same period in 2019. Age, sex, mechanism, anatomical region, and treatment modality were compared, as were fracture clinic attendances within the receiving regional major trauma centre (MTC) between the two periods. Results. Paediatric trauma admissions across the region fell by 33% (197 vs 132) with a proportional increase to 59% (n = 78) of admissions to the MTC during lockdown compared with 28.4% in 2019 (N = 56). There was a reduction in manipulation under anaesthetic (p = 0.015) and the use of Kirschner wires (K-wires) (p = 0.040) between the two time periods. The median time to surgery remained one day in both (2019 IQR 0 to 2; 2020 IQR 1 to 1). Supracondylar fractures were the most common reason for fracture clinic attendance (17.3%, n = 19) with a proportional increase of 108.4% vs 2019 (2019 n = 20; 2020 n = 19) (p = 0.007). While upper limb injuries and falls from play apparatus, equipment, or height remained the most common indications for admission, there was a reduction in sports injuries (p < 0.001) but an increase in lacerations (p = 0.031). Fracture clinic management changed with 67% (n = 40) of follow-up appointments via telephone and 69% (n = 65) of patients requiring cast immobilization treated with a 3M Soft Cast, enabling self-removal. The safeguarding team saw a 22% reduction in referrals (2019: n = 41, 2020: n = 32). Conclusion. During this viral pandemic, the number of trauma cases decreased with a change in the mechanism of injury, median age of presentation, and an increase in referrals to the regional MTC. Adaptions in standard practice led to fewer MUA, and K-wire procedures being performed, more supracondylar fractures managed through clinic and an increase in the use of removable cast.

Acute metatarsal fractures are a common extremity injury. While surgery may be recommended to reduce the risk of nonunion or symptomatic malunion, most fractures are treated with nonoperative management. However, there is significant variability between practitioners with no consensus among clinicians on the most effective nonoperative protocol, despite how common the form of treatment. This systematic review identified published conservative treatment modalities for acute metatarsal fractures and compares their non-union rate, chronic pain, and length of recovery, with the objective of identifying a best-practices algorithm. Searches of CINAHL, EMBASE, MEDLINE, and CENTRAL identified clinical studies, level IV or greater in LOE, addressing non-operative management strategies for metatarsal fractures. Two reviewers independently screened the titles, abstracts, and full texts, extracting data from eligible studies. Reported outcome measures and complications were descriptively analyzed. Studies were excluded if a rehabilitation program outlining length of immobilization, weight-bearing and/or strengthening approaches was not reported. A total of 12 studies (8 RCTs and 4 PCs), from the 2411 studies that were eligible for title screening, satisfied inclusion criteria. They comprised a total of 610 patients with acute metatarsal fractures, with a mean age of 40.2 years (range, 15 – 82). There were 6 studies that investigated avulsion fractures, 2 studies on true Jones fractures, and 4 studies with mixed fracture types. Studies assessed a variety of treatment modalities including: WB and NWB casts, elasticated support bandages, hard-sole shoes, plaster slippers, metatarsal shoe casts, and air cast boots. Most studies investigated the outcomes of NWB casts and elasticated support bandages. The NWB short leg cast had no reported non-unions, delayed-unions, or refractures for avulsion fractures. In true Jones fractures, there was an average non-union rate of 23.6% (range, 5.6 – 27.8%), delayed-union rate of 11.8% (range, 5.6 – 18.8%), and refracture rate of 3% (range, 0 – 5.6%). Overall, the average AOFAS score was 87.2 (range, 84 – 91.7) and the average VAS score was 83.7 (range, 75 – 93). The elasticated support bandage had an average non-union rate of 3.4% (range, 0 – 12%), and delayed-union rate of 3.8% for acute avulsion fractures, with no reported refractures. No included study arm investigated outcomes of elasticated support bandages for the true Jones fracture. The average AOFAS score for elasticated support bandages was 93.5 (range, 90 – 100). The average VAS score was 88.9 (range, 90 – 100). Most acute metatarsal fractures heal well, with good-to-excellent functional outcomes and moderate-to-high patient satisfaction. Conservative strategies for avulsion fractures are highly successful and based on this data the authors recommend patients undergo a schedule that involves 3 – 4 weeks in an elasticated support bandage, short leg cast, or equivalent, and WB thereafter as tolerated, with return-to-activity after clinical union. Despite poorer conservative outcomes for true Jones fractures, patients should undergo 8 weeks in a NWB short leg cast, followed by a walking cast or hard-sole shoe for an additional 4 – 6 weeks, or until clinical union. However, surgical consultation is recommended

Abstract. The aim is to describe the safety and efficacy of TAL in out-patient clinics when managing diabetic forefoot ulcers. Patients and Methods. Consecutive patients, who underwent TAL and had minimum 12m follow-up were analysed. Forceful dorsiflexion of ankle was avoided and patients were encouraged to walk in Total contact cast for 6-weeks and further 4-weeks in walking boot. Results. 142 feet in 126 patients underwent this procedure and 86 feet had minimum follow-up of 12m. None had wound related problems. Complete transection of the tendon was noted in 3 patients and one-patient developed callosity under the heel. Ulcers healed in 82 feet (96%) within 10 weeks however in 12 feet (10%), the ulcer recurred or failed to heal. MRI showed plantar flexed metatarsals with joint subluxation. The ulcer in this subgroup healed following proximal dorsal closing wedge osteotomy. Conclusion. Tightness of gastroc-soleus-Achilles complex and subluxed MTP joint from soft tissue changes due to motor neuropathy result in increased forefoot plantar pressures. A 2-stage approach as described result in long-term healing of forefoot ulcers, and in 96% of patients, the ulcer healed following TAL alone. TAL is a safe and effective out-patient procedure with improved patient satisfaction outcomes

There is no agreement as to the superiority or specific indications for cast treatment, percutaneous pinning or open fracture fixation for Bennett's fractures of the thumb metacarpal. We undertook this study to compare the outcomes of treatment for patients treated for Bennett's fracture in the medium term. We reviewed 33 patients treated in our unit for a bennett's fracture to the thumb metacarpal with closed reduction and casting. Each patient was matched with a patient treated surgically. Patients were matched for sex, age, Gedda grade of injury and hand dominance. Patients were reviewed at a minimum of 5-years and 66-patients were reviewed in total. Patients were examined clinically and also asked to complete a DASH questionnaire score and the brief Michigan hand questionnaire. Follow up plain radiographs were taken of the thumb and these were reviewed and graded for degenerative change using the Eaton-Littler score. Sixty-six patients were included in the study, with 33 in the surgical and non-surgical cohorts respectively. The average age was 39 years old. In each cohort, 12/33 were female, 19/33 were right-handed with 25% of individuals injuring their dominant hand. In each coort there were 16 Grade 1 fractures, 4 Grade 2 and 13 Grade 3 fractures. There was no difference between the surgically treated and cast-treatment cohorts of patients when radiographic arthritis, pinch grip, the brief Michigan Hand Questionnaire and pain were assessed at final review. The surgical cohort had significantly lower DASH scores at final follow-up. There was no significant difference in the normalised bMHQ scores. Our study was unable to demonstrate superiority of either operative or non-operative fracture stabilization. Patients in the surgical cohort reported superior satisfaction and DASH scores but did not demonstrate any superiority in any other objectively measured domain
