The aims of this study was to determine the incidence of malnutrition in children with supracondylar fractures. It was hypothesised that the presence of malnutrition will increase the severity type of fractures. The study was a retrospective, cross-sectional study at a single institution. Children between 0 years and 12 years of age, who sustained documented supracondylar fracture treated surgically as a result of low velocity trauma were included in the study. Patients who sustained high velocity trauma, who had known bone disorders or had incomplete chart data, were excluded from the study Data was captured from children's’ notes who have been treated surgically for supracondylar fractures from casualty, theatre and the clinic notes. The nutritional status of children and fracture grade were identified and the two sets of data were compared against each other to try to identify a possible relation between fracture severity and malnutrition. Data was analysed in STATA and 5% level of significance was used to signify statistically significant associations. 150 patients were identified and included in the study. The majority of patients reviewed were in the normal nutritional range according to their z-scores. The severity of the fracture was not only associated with a poorer nutritional status however children with high and low z-scores (over weight as well as undernourished children) had the more severe fracture patterns, while children with normal z-scores had a fracture patterns of varying severity. Children who were malnourished were more likely to sustain more severe fracture types. The results highlighted the need for all children to have a good nutritional status as this may play a role in preventing more complex fractures

Open tibia fractures are common injuries in our paediatric population and are often associated with high-energy trauma such as pedestrian-vehicle accidents. At our institution, these injuries are routinely treated with debridement and mono-lateral external fixation. The purpose of this study was to determine the outcome of open tibia fractures treated according to this protocol, as well as the complication rate and factors contributing to the development of complications. We performed a retrospective folder review of all patients with open tibia fractures that were treated according to our protocol from 2015–2019. Patients treated by other means, who received primary treatment elsewhere, and with insufficient data, were excluded. Data was collected on presenting demographics, injury characteristics, management, and clinical course. Complications were defined as pin tract infections, delayed- or non-union, malunion, growth arrest, and neurovascular injury. Appropriate statistical analysis was performed. One-hundred-and-fifteen fractures in 114 children (82 males) with a median age of 7 years (IQR 6–9) were included in the analysis. Pedestrian vehicle accidents (PVA's) accounted for 101 (88%) of fractures, and the tibial diaphysis was affected in 74 cases (64%). Fracture severity was equally distributed among the Gustillo-Anderson grades. The median Abbreviated Injury Score was 4 (IQR 4;5). Ninety-five fractures (83%) progressed to uneventful union within 7 weeks. Twenty patients (17%) developed complications, with delayed union and fracture site infections being the most common complications. Gustillo-Anderson Grade 3 fractures, an increased Abbreviated Injury Score, and the need for advanced wound closure techniques were risk factors for developing complications. Surgical debridement and external fixation in a simple mono-lateral frame is an effective treatment for open tibia fractures in children and good outcomes were seen in 83% of patients. More severe injuries requiring advanced wound closure were associated with the development of complications

Despite the current trend favoring surgical treatment of displaced intra-articular calcaneal fractures (DIACFs), studies have not been able to demonstrate superior functional outcomes when compared to non-operative treatment. These fractures are notoriously difficult to reduce. Studies investigating surgical fixation often lack information about the quality of reduction even though it may play an important role in the success of this procedure. We wanted to establish if, amongst surgically treated DIACF, an anatomic reduction led to improved functional outcomes at 12 months. From July 2011 to December 2020, at a level I trauma center, 84 patients with an isolated DIACF scheduled for surgical fixation with plate and screws using a lateral extensile approach were enrolled in this prospective cohort study and followed over a 12-month period. Post-operative computed tomography (CT) imaging of bilateral feet was obtained to assess surgical reduction using a combination of pre-determined parameters: Böhler's angle, calcaneal height, congruence and articular step-off of the posterior facet and calcaneocuboid (CC) joint. Reduction was judged anatomic when Böhler's angle and calcaneal height were within 20% of the contralateral foot while the posterior facet and CC joint had to be congruent with a step-off less than 2 mm. Several functional scores related to foot and ankle pathology were used to evaluate functional outcomes (American Orthopedic Foot and Ankle Score - AOFAS, Lower Extremity Functional Score - LEFS, Olerud and Molander Ankle Score - OMAS, Calcaneal Functional Scoring System - CFSS, Visual Analog Scale for pain - VAS) and were compared between anatomic and nonanatomic DIAFCs using Student's t-test. Demographic data and information about injury severity were collected for each patient. Among the 84 enrolled patients, 6 were excluded while 11 were lost to follow-up. Thirty-nine patients had a nonanatomic reduction while 35 patients had an anatomic reduction (47%). Baseline characteristics were similar in both groups. When we compared the injury severity as defined by the Sanders’ Classification, we did not find a significant difference. In other words, the nonanatomic group did not have a greater proportion of complex fractures. Anatomically reduced DIACFs showed significantly superior results at 12 months for all but one scoring system (mean difference at 12 months: AOFAS 3.97, p = 0.12; LEFS 7.46, p = 0.003; OMAS 13.6, p = 0.002, CFSS 7.5, p = 0.037; VAS −1.53, p = 0.005). Univariate analyses did not show that smoking status, worker's compensation or body mass index were associated with functional outcomes. Moreover, fracture severity could not predict functional outcomes at 12 months. This study showed superior functional outcomes in patients with a DIACF when an anatomic reduction is achieved regardless of the injury severity

Introduction. Open fractures of the tibia are disabling injuries with a significant risk of deep infection. Treatment involves early antibiotic administration, early and aggressive surgical debridement, and may require complex soft tissue coverage techniques. The extent of disruption to the skin and soft-tissue envelope often varies, with ‘simple’ open fractures (defined by the Orthopaedic Trauma Society (OTS) open fracture severity classification) able to be closed primarily, whilst others may require shortening or soft-tissue reconstruction. This study aimed to determine whether OTS simple tibial open fractures received different rates of adequate debridement and plastic surgical presence at initial debridement, compared with OTS complex injuries, and whether rates of fracture-related infection, nonunion, or reoperation differed between the groups. Materials & Methods. A consecutive series of open tibia fractures managed at a tertiary UK Major Trauma Centre between January 2021 and November 2022 were included. Patient demographics, injury characteristics, timing of antibiotic delivery, timing and method of definitive fixation, and frequency of plastic surgical presence at initial debridement were retrospectively collected. The delivery of bone ends at initial debridement was used as a proxy for adequacy of surgical debridement. The primary outcome measure was rate of fracture-related infection, secondary outcomes included rates of reoperation, nonunion, and amputation. Chi2 Tests and independent samples T-tests were used to assess nominal and continuous outcomes respectively between simple and complex injuries. Ordinal data was assessed using nonparametric equivalent tests. Results. 79 patients with open fractures of the tibia were included. 70.8% of patients were male, with mean age 50.4 years (SD 19.2) and BMI 26.4 Kg/m2 (SD 6.0). Injuries were mostly sustained by low-energy falls (n = 28, 35.4%) and from road traffic accidents (n = 26, 32.9%). 27 (34.2%) were OTS simple open fractures. Simple open fractures were most commonly Gustillo-Anderson grade 1 (38.5%), or 2 (30.8%), whilst complex open fractures were mostly grade 3B (66.7%) (p < 0.001). Fracture-related infection rates in OTS simple and complex open fractures were 25.9% and 25.5% respectively (p = 0.967), and nonunion rates were 32% and 37.8% (p = 0.637). Primary amputation was less common in simple (0%) than in complex open fractures (20%, p = 0.012), there were no differences in delayed amputation rates (7.4% and 6% respectively, p = 0.811). Simple open fractures were less likely to have plastic surgeons present at initial debridement compared to complex open fractures (18.5% and 44%, p = 0.025), and less likely to have bone ends delivered through the skin at initial debridement (25.9% and 61.2%, p = 0.003). There were no differences in patient age, delays to antibiotic administration, or reoperation rates between OTS simple and OTS complex fractures (p > 0.05). Conclusions. Despite involving less significant soft tissue injury, OTS simple open tibia fractures had comparable deep infection and nonunion rates to complex fractures and received early plastic surgical input and adequate debridement less frequently. The severity of open fractures with less significant soft tissue injury may be underrecognized and therefore undertreated, although further prospective study is needed

Many studies report the incidence and prevalence of surgical site infections (SSIs) following open fractures; however, there is limited information on the treatment and subsequent outcomes of superficial SSIs in open fracture patients. There is also a lack of clinical studies describing the prognostic factors that are associated with failure of antibiotic treatment (non-operative) for superficial SSI. To address this gap, we used data from the FLOW (Fluid Lavage in Open Fracture Wounds) trial to determine how successful antibiotic treatment was for superficial SSIs and to identify prognostic factors that could be predictive of antibiotic treatment failure. This is a secondary analysis of the FLOW trial dataset. The FLOW trial included 2,445 operatively managed open fracture patients. FLOW participants who had a non-operatively managed superficial SSI diagnosed in the 12 months post-fracture were included in this analysis. Participants were grouped into two categories: 1) participants whose superficial SSI resolved with antibiotics alone and 2) participants whose SSI did not resolve with antibiotics alone (defined as requiring surgical management or SSI being unresolved at final follow-up (12-months post-fracture for the FLOW trial)). Antibiotic treatment success and the date when this occurred was defined by the treating surgeon. A logistic binary regression analysis was conducted to identify factors associated with superficial SSI antibiotic success. Based on biologic rationale and previous literature, a priori we identified 13 (corresponding to 14 levels) potential factors to be included in the regression model. Superficial SSIs were diagnosed in168 participants within 12 months of their fracture. Of these, 139 (82.7%) had their superficial SSI treated with antibiotics alone. The antibiotic treatment was successful in resolving the superficial SSI in 97 participants (69.8%) and unsuccessful in resolving the SSI in 42 participants (30.2%). We found that superficial SSIs that were diagnosed later in follow-up were associated with failure of treatment with antibiotic alone (Odds ratio 1.05 for every week in diagnosis delay, 95% Confidence Interval 1.004–1.099; p=0.03). Age, sex, fracture severity, fracture pattern, wound size, time from injury to initial surgical irrigation and debridement were not associated with antibiotic treatment failure. Our secondary analysis of prospectively collected FLOW data found antibiotics alone resolved superficial SSIs in 69.8% of patients diagnosed with superficial SSIs. We also found that superficial SSIs that were diagnosed earlier in follow-up were associated with successful treatment with antibiotics alone. This suggests that if superficial SSIs are diagnosed and treated promptly, there is a higher probability that they will resolve with antibiotic treatment

Purpose. Isolated fractures of femoral condyle in the coronal plane (Hoffa fracture) is rare and is surgically challenging to treat. 44 patients were operated between 2004–2014. The aim was to retrospectively assess the fracture patterns, fixation done and functional outcome. Methods. All injuries resulted from direct trauma to the knee out of which 36 were due to road traffic accidents.38 were closed injuries and the rest open.35 involved lateral condyle, 8 involved medial condyle and one was bicondylar type. All were anatomically reduced with fixation decided based on preoperative radiographs, CT scan and intra-op observation. Early passive motion and isometric exercises were started but kept non-weight bearing for 6–8 weeks. The mean follow up period was five years. Outcomes were measured using Neer's scoring system and International Knee Society Documentation Committee (IKDC) Functional Score. Results. 26 patients had excellent outcome, 14 had satisfactory and 4 had unsatisfactory outcome which corresponded with the specified fracture severity pattern. Uniformly excellent results were obtained in all simple pattern fractures, whereas comminuted fracture patterns were more challenging to treat with variable outcomes. Conclusion. In our retrospective observational study, we found that each fracture had specific pattern which dictated the treatment plan and the prognosis. Subsequently we grouped the fractures and proposed a classification system that would specify the pattern of fracture and dictate the type of fixation preferred. We conclude that therapeutic outcome is significantly affected by the amount of articular surface comminution, posterior cortex comminution, attainment of anatomical reduction and stable fixation

Objective. To determine differences in fracture stability and functional outcome between synthetic bone graft and allograft/autograft with internal fixation of tibia plateau metaphyseal defects. Patient & Methods. Between 2007- 2008, 84 consecutive cases of internal fixation of tibia plateaux were identified from our theater logbook. 29 patients required additional autologous, allogenic bone graft, or synthetic bone graft substitute to ensure fracture stability. 5 patients were excluded due to lost to follow up leaving a cohort of 24 patients. Hydroxyapatite calcium carbonate synthetic bone graft was utilised in 14 patients (6 male and 8 female). Allograft/autograft were utilised in the remaining 10 patients (6 male and 4 female). All 24 patients had closed fractures, classified using the AO and Schatzker classification. Roentograms at presentation, post-operatively and regular follow-up till 12 months were analysed for maintenance of reduction, early and late subsidence of the articular surface. Functional outcomes such as knee range of movement and WOMAC Knee scores were compared between groups. Results. There was no significant statistical difference between groups for post-operative joint reduction, long term subsidence, and WOMAC scores. The degree of subsidence was not related to age or fracture severity. Maintenance of knee flexion was found to be better in the allograft/autograft group (p=0.015) when compared between groups. Multivariate analysis compared graft type, fracture severity, postoperative reduction, subsidence rate, range of movement and WOMAC score. The only finding was a statistical significant (p=0.025) association with the graft type and range of movement. Conclusion. Allograft/autograft may allow better recovery of long-term flexion, possibly due to reduced inflammatory response compared with synthetic bone graft. However, all other parameters such as maintenance of joint reduction and subjective outcome measures were comparable with the use of hydroxyapatite calcium carbonate bone graft. This study shows that synthetic bone graft is a suitable option in fixation of unstable tibia plateau fractures, avoiding risk of viral disease transmission with allograft and donor site morbidity associated with autograft

It has been proposed that the amount of energy transferred to the bone during a high velocity projectile injury determines the extent of bony injury. We studied the validity of this theory Fresh rear skeletally mature deer femurs were subjected to progressively increasing velocity projectile injuries within a pneumatic ballistic chamber with non-deforming steel spheres capturing the energy transferred. Analysis of fracture severity was performed including micro computer tomography analysis of micro-fractures. The effect of projectile caliber size was then analyzed. Characteristic fractures patterns were observed with fracture lines extending radially from the impact site, often propagating longitudinally along the sample. It was found that a greater energy transfer resulted in more severe fracture for a given projectile. However, fractures of differing severity were produced by different projectiles for similar energy transfer. Neither specific energy transfer nor energy density could explain this phenomenon. Although energy transfer plays a role in ballistic fracture, it is not the sole determinant. Other factors such as contact surface area, projectile mass and angle of impact may need to be considered

Introduction. To compare the union rates and post-operative mobility of antegrade intramedullary nailing of osteoporotic traumatic supracondylar femoral fractures (AO classification A to C2) with those of plating. Materials/Methods. We studied any traumatic intra or extra-articular supracondylar femoral fracture from 2005–2010. Patients were either admitted directly to our level 1 trauma centre or were referred from another hospital. Nineteen patients were identified, consisting of primarily fixation with five antegrade nails and fourteen plates. We defined osteoporotic bone as being present in anyone over sixty years old or who had a clinical diagnosis. One nail and six plates were excluded due to young age or fracture severity. This left four nails, six less invasive stabilisation system plates and two dynamic condylar screw plates. Both groups were comparable with respect to age, sex and AO fracture classification. Results. There was a significant difference in achieving union between the two groups (p=0.040). Union occurred within three months in all four fractures in the nail group but only three fractures (38%) united after primary fixation in the plate group. There were two failures due to screw pullout, one failure due to screw breakage, one broken plate after delayed-union and one screw breakage after non-union. The patients in the nail group had better mobility and less pain than the plate group but the difference was not statistically significant. Conclusion. We have shown that for patients with osteoporotic, supracondylar femoral fractures, fixation with an antegrade IM nail provides significantly better healing compared to plate fixation

The outcome of 77 high energy tibial plateau fractures treated by locking or conventional plating was reviewed. The aim of the study was to determine if there was any advantage of locking plates in reducing the complication rates associated with fixation of these injuries. All patients had a high energy injury pattern (medial or bicondylar plateau fractures). There were 32 locked plates and 45 non-locking plates used. Compartment syndrome complicated 5 patients (16%) in the locked plate group and 3 (7%) in the non-locked group (p = 0.198). Superficial infection occurred in 4 (13%) patients with locked plates and 7 (16%) patients with non-locked plates. Thromboembolic complications occurred in 3 (7%) patients treated with non-locked plates. There were no thrombembolic complications in the locked plate group (p = 0.135). Overall, malunion of the plateau occurred in 10 (22%) patients treated with non-locked plates compared to 7 (22%) patients who received locked plates. This was due to residual malreduction in 4 (13%) patients in the locked plate group and 6 (13%) patients in the non-locked plate group at the time of surgery. In the remaining cases loss of reduction after fixation occurred in 4 (9%) patients who received non-locked plates and in 3 (9%) patients who were treated with locked plates. No statistically significant difference was noted in the treatment outcomes of patients managed with locked plates or non-locked plates, regardless of fracture severity. We concluded that there is no definite advantage associated with the use of locked plating for high energy tibial plateau fractures

Purpose of study:. Up to 30% of distal femur fractures treated with a locked plate have problems with union. Distal femur locked plates have become a very popular means of internal fixation because of their ability to provide stable distal peri-articular fixation. In spite of this enthusiasm however several studies have reported significant problems with healing. In the distal femur it is recognized that locked plate fixation may be too rigid if used in certain configurations preventing the essential micro movement required for biological healing. Implant failure may arise from rigid configurations that cause excessive hardware stress concentrations. In an attempt to address these problems longer plates and an increased working length have been proposed to reduce construct rigidity. The purpose of our study is to investigate whether an increased working length translates into improved healing. Description of method:. We undertook a retrospective review of 92 consecutive cases performed at our institution from 2007–2010. Case notes and X-rays were reviewed. Working length, plate to fracture zone ratios and working length to fracture zone ratios were calculated. Union was assessed radiographically and clinically. Covariates of smoking, age, sex and fracture severity were included. Outcomes considered were union or established non-union. Delayed union was defined as union after 20 weeks. Summary of results:. Median time to union was 16.9 weeks. 11 delayed unions (23.4%, 95%CI(10.8–36.0%)), 3 non-unions (6.4% 95%CI(0.0–13.6%)) and no implant failures were recorded. Our data are consistent with the previously reported proportion of distal femur fractures treated with a locked plate that have problems with union. Although trends were present, no significant associations between impaired healing and exposure variables were found. Conclusion:. While biomechanical studies have demonstrated increased flexibility of longer plates with an increased working length, clinically this did not translate into significantly improved fracture healing in our study

Background. Angular stable volar locking plates have become increasingly popular for more comminuted fractures of the distal radius. Newer designs of plates have been thicker in profile and incorporate more options for distal fragment fixation. Although they have been shown to be successful at maintaining reduction to allow early mobilisation the main drawback is from screw cut-out. In our practice we have noticed that the newer style of plates that offer more rigid fixation has lead to more instances of screw cut-out. We aimed to quantify the minimum number of locking pegs and or screws need to maintain the operative reduction. Method. We retrospectively looked at a series of 46 patients that had undergone volar plating. We assessed the fracture severity on pre-operative films (according to AO classification) and compared radiographic parameters (volar tilt VT, radial inclination RI and radial height RH) on post-operative films. We calculated the amount of reduction lost from initial post operative x-rays to radiographs taken when union was confirmed. We compared this to the number of locking units used to fix the distal radius and also the configuration they were inserted, i.e. the number in the radial and middle columns. Results. The mean loss of reduction in all plates was 0.9mm of RH, 2.2degs of RI and 2.8degs of VT. There was no difference in mean ‘reduction lost’ between plates that had a total of 2 or 3 locking units (RH 1mm and 1mm, RI 2.0deg and 2.7deg and VT 2.9deg and 3.2 deg respectively). This was also case when sub-analysing more severe OTA Type C fractures. Conclusion. Only one locking peg is needed under each column for adequate stability (i.e. a total of two distal locking units). Any more than this confers no additional benefit in maintaining reduction, ever in more severe fractures. The extra rigidity provided by more locking screws/pegs and also thicker plates: as provided by newer designs of plates, may make them more prone to cut out

To examine all open fractures presenting to Bundaberg Base Hospital—from January 2007 to January 2009—by monitoring the clinical course of the patients, with attention to the time intervals between injury, presentation and orthopaedic treatment. The complications of treatment and the implications for future practice were also examined. A search was performed of all open fractures and compound fractures during the period of January 2007 until January 2009. The eligible patients were selected and their charts reviewed. The time of the injury, the time they presented to the emergency department (ED) and the time to orthopaedic treatment were noted. The site of the fracture, the Gustillo classification and the number of days of admission were recorded. Complications of the fractures were investigated. The impact of time delays and fracture severity on subsequent infections were correlated. A total of 127 admissions were recorded, 38 were excluded and 89 open fractures were included in the study: 54 upper limb, 34 lower limb and 1 pelvic fracture. Thirty-six patients had Gustillo I, 34 II, 9 IIIa, and 11 IIIb classifications. Patient arrival times were as follows: less than one hour (19%), 1–3 hours (44%), 3–6 hours (26%), 6–12 hours (8%) and greater than 12 hours (2%). From presentation, 28% of patients received treatment in 1–3 hours, 3–6 hours (27%), 6–12 hours (22%) and greater than 12 hours (22%). 40.4% of patients received treatment within 6 hours of injury and 59.5% greater than 6 hours. 33% of patients stayed in hospital 24 hours, 1–3 days (44%), 3–7 days (15%) and for greater than one week (1%). There were a total of 17 complications (19%), of which 11 (12%) were associated with infections. Of these, six were superficial wound infections and five were deep infections. Of these deep infections, two were associated with non-unions and one with a mal-union. Four complications were associated with non-infectious non-unions, one non-infectious mal-union. One had a missing bone fragment. Complications were found to be more prevalent when there was delayed treatment of the fractures. The results demonstrate that the majority of open fractures treated are upper limb and Gustillo I in classification. The complication rate for open fractures during the two year period was 19%. These findings provide a base for continued monitoring of open fracture management at Bundaberg Base Hospital

Aims

The increase in prescription opioid misuse and dependence is now a public health crisis in the UK. It is recognized as a whole-person problem that involves both the medical and the psychosocial needs of patients. Analyzing aspects of pathophysiology, emotional health, and social wellbeing associated with persistent opioid use after injury may inform safe and effective alleviation of pain while minimizing risk of misuse or dependence. Our objectives were to investigate patient factors associated with opioid use two to four weeks and six to nine months after an upper limb fracture.
