Aims. To compare results of institutional preferences with regard to treatment of soft tissues in the setting of open tibial shaft fractures. Methods. We present a retrospective review of open tibial shaft fractures at two high-volume level 1 trauma centres with differing practices with regard to the acute management of soft tissues. Site 1 attempts acute primary closure, while site 2 prefers delayed closure/coverage. Comparisons include percentage of primary closure, number of surgical procedures until definitive closure, percentage requiring soft tissue coverage, and percentage of 90-day wound complication. Results. Overall, there were 219 patients at site 1 and 282 patients at site 2. Differences in rates of acute wound closure were seen (168 (78%) at site 1 vs 101 (36%) at site 2). A mean of 1.5 procedures for definitive closure was seen at site 1 compared to 3.4 at site 2. No differences were seen in complication, nonunion, or amputation rates. Similar results were seen in a sub-analysis of type III injuries. Conclusion. Comparing outcomes of open tibial shaft fractures at two institutions with different rates initial wound management, no differences were seen in 90-day wound complications, nonunion rates, or need for amputation. Attempted acute closure resulted in a lower number of planned secondary procedures when compared with planned delayed closure. Providers should consider either acute closure or delayed coverage based on the injury characteristics, surgeon preference and institutional resources without concern that the decision at the time of index surgery will lead to an increased risk of complication.

Tibial shaft fracture occurs commonly in the young active population with high demands. Tibial fracture is potentially life changing. There are no published studies with long-term follow-up to provide accurate prognostic information regarding return to leisure activities, employment and driving. We aim to define the patient demographic and mechanism of injury and quantify the time period following tibial shaft fracture to return to sport and sporting level achieved at long-term follow-up. A retrospective multi-centre study was performed. Data collection was by questionnaire including Tegner activity scale score for sporting level and closed questioning on employment and driving. Ninety-three patients were recruited with an average 46 month (18–64mo) follow-up period. Patients were predominantly male (77%) with a median age at injury of 37 years. Road traffic accidents were responsible for 43% of injuries; sport 31%; falls 25% and assault 1%. High energy mechanisms accounted for 49% of injuries Seventy-eight percent of patients felt that prognostic information given at the time of injury was inaccurate. At follow-up, only 31% had regained their original level of sporting ability. Median Tegner score prior to injury score was 5 and at 18 months the mean score fell by 1.85. Patients sustaining high energy injuries were worst affected, dropping an average of 2.13 compared to low energy mechanisms with an average fall of 1.35 on the Tegner scale (p=0.503). High demand patients had a greater reduction in functional outcome, with a fall of 0.8 for patients with pre-injury activity level of 1–3 compared to the fall of 2.6 on the scale for more active patients scoring 7–9 pre-injury. Tibial fracture can result in significant long-term morbidity. Patients sustaining high energy injuries and high demand patients have significantly worse outcome. Patients are unlikely to achieve their pre-injury level of sporting activity at 2 years

Aims. Posterior malleolar (PM) fractures are commonly associated with ankle fractures, pilon fractures, and to a lesser extent tibial shaft fractures. The tibialis posterior (TP) tendon entrapment is a rare complication associated with PM fractures. If undiagnosed, TP entrapment is associated with complications, ranging from reduced range of ankle movement to instability and pes planus deformities, which require further surgeries including radical treatments such as arthrodesis. Methods. The inclusion criteria applied in PubMed, Scopus, and Medline database searches were: all adult studies published between 2012 and 2022; and studies written in English. Outcome of TP entrapment in patients with ankle injuries was assessed by two reviewers independently. Results. Four retrospective studies and eight case reports were accepted in this systematic review. Collectively there were 489 Pilon fractures, 77 of which presented with TP entrapment (15.75%). There were 28 trimalleolar fractures, 12 of which presented with TP entrapment (42.86%). All the case report studies reported inability to reduce the fractures at initial presentation. The diagnosis of TP entrapment was made in the early period in two (25%) cases, and delayed diagnosis in six (75%) cases reported. Using modified Clavien-Dindo complication classification, 60 (67%) of the injuries reported grade IIIa complications and 29 (33%) grade IIIb complications. Conclusion. TP tendon was the commonest tendon injury associated with pilon fracture and, to a lesser extent, trimalleolar ankle fracture. Early identification using a clinical suspicion and CT imaging could lead to early management of TP entrapment in these injuries, which could lead to better patient outcomes and reduced morbidity.

Aims. Lower limb fractures are common in low- and middle-income countries (LMICs) and represent a significant burden to the existing orthopaedic surgical infrastructure. In high income country (HIC) settings, internal fixation is the standard of care due to its superior outcomes. In LMICs, external fixation is often the surgical treatment of choice due to limited supplies, cost considerations, and its perceived lower complication rate. The aim of this systematic review protocol is identifying differences in rates of infection, nonunion, and malunion of extra-articular femoral and tibial shaft fractures in LMICs treated with either internal or external fixation. Methods. This systematic review protocol describes a broad search of multiple databases to identify eligible papers. Studies must be published after 2000, include at least five patients, patients must be aged > 16 years or treated as skeletally mature, and the paper must describe a fracture of interest and at least one of our primary outcomes of interest. We did not place restrictions on language or journal. All abstracts and full texts will be screened and extracted by two independent reviewers. Risk of bias and quality of evidence will be analyzed using standardized appraisal tools. A random-effects meta-analysis followed by a subgroup analysis will be performed, given the anticipated heterogeneity among studies, if sufficient data are available. Conclusion. The lack of easily accessible LMIC outcome data, combined with international clinical guidelines that are often developed by HIC surgeons for use in HIC environments, makes the clinical decision-making process infinitely more difficult for surgeons in LMICs. This protocol will guide research on surgical management, outcomes, and complications of lower limb shaft fractures in LMICs, and can help guide policy development for better surgical intervention delivery and improve global surgical care.

Aims. The aim of this study was to establish a reliable method for producing 3D reconstruction of sonographic callus. Methods. A cohort of ten closed tibial shaft fractures managed with intramedullary nailing underwent ultrasound scanning at two, six, and 12 weeks post-surgery. Ultrasound capture was performed using infrared tracking technology to map each image to a 3D lattice. Using echo intensity, semi-automated mapping was performed to produce an anatomical 3D representation of the fracture site. Two reviewers independently performed 3D reconstructions and kappa coefficient was used to determine agreement. A further validation study was undertaken with ten reviewers to estimate the clinical application of this imaging technique using the intraclass correlation coefficient (ICC). Results. Nine of the ten patients achieved union at six months. At six weeks, seven patients had bridging callus of ≥ one cortex on the 3D reconstruction and when present all achieved union. Compared to six-week radiographs, no bridging callus was present in any patient. Of the three patients lacking sonographic bridging callus, one went onto a nonunion (77.8% sensitive and 100% specific to predict union). At 12 weeks, nine patients had bridging callus at ≥ one cortex on 3D reconstruction (100%-sensitive and 100%-specific to predict union). Presence of sonographic bridging callus on 3D reconstruction demonstrated excellent reviewer agreement on ICC at 0.87 (95% confidence interval 0.74 to 0.96). Conclusion. 3D fracture reconstruction can be created using multiple ultrasound images in order to evaluate the presence of bridging callus. This imaging modality has the potential to enhance the usability and accuracy of identification of early fracture healing. Cite this article: Bone Joint Res 2021;10(12):759–766

Tibial shaft fractures require surgical stabilization preferably by intramedullary nailing. However, patients often report functional limitations even years after the injury. This study investigates the influence of the surgical approach (transpatellar vs. parapatellar) on gait performance and patient reported outcome six months after surgery. Twenty-two patients with tibial shaft fractures treated by intramedullary nailing through a transpatellar approach (TP: n=15, age 41±15, BMI 24±3) or a parapatellar approach (PP: n=7, age 34±15, BMI 23±2) and healthy, matched controls (n=22, age 39±13, BMI 24±2) were assessed by instrumented motion analysis six months after intramedullary nailing. Short musculoskeletal function assessment questionnaire (SMFA) as well as kinematic and kinetic gait data were collected during level walking. Comparisons among approach methods and control group were performed by analysis of variance and Mann-Whitney test. Six months after surgery, knee kinetics in both groups differed significantly compared to controls (p <.04). The approach method affected gait speed (TP: p = .002; PP: p = .08) and knee kinematics in the early stance phase (TP: p = .011; PP: p = .082), with the parapatellar approach showing a more favorable outcome. However, the difference between patient groups was not significant for any of the assessed gait parameters (p > .2). Also, no differences could be found in the bother index (BI) or function index (FI) of SMFA between surgical approach methods (BI: TP: Mdn = 7.2, PP: Mdn = 9.4; FI: TP: Mdn = 10.3, PP: Mdn = 9.2, p > .7). Our study demonstrates, that six months after surgery for tibial shaft fractures functional limitations remain. These limitations appear not to be different for either a trans- or a parapatellar approach for the insertion of the intramedullary nail. The findings of this study are limited by the relatively short follow up time period and small number of patients. Future studies should investigate the source of the functional limitation after intramedullary nailing of tibial shaft fractures

Aims. Using tibial shaft fracture participants from a large, multicentre randomized controlled trial, we investigated if patient and surgical factors were associated with health-related quality of life (HRQoL) at one year post-surgery. Methods. The Study to Prospectively Evaluate Reamed Intramedullary Nails in Patients with Tibial Fractures (SPRINT) trial examined adults with an open or closed tibial shaft fracture who were treated with either reamed or unreamed intramedullary nails. HRQoL was assessed at hospital discharge (for pre-injury level) and at 12 months post-fracture using the Short Musculoskeletal Functional Assessment (SMFA) Dysfunction, SMFA Bother, 36-Item Short Form 36 (SF-36) Physical, and SF-36 Mental Component scores. We used multiple linear regression analysis to determine if baseline and surgical factors, as well as post-intervention procedures within one year of fracture, were associated with these HRQoL outcomes. Significance was set at p < 0.01. We hypothesize that, irrespective of the four measures used, prognosis is guided by both modifiable and non-modifiable factors and that patients do not return to their pre-injury level of function, nor HRQoL. Results. For patient and surgical factors, only pre-injury quality of life and isolated fracture showed a statistical effect on all four HRQoL outcomes, while high-energy injury mechanism, smoking, and race or ethnicity, demonstrated statistical significance for three of the four HRQoL outcomes. Patients who did not require reoperation in response to infection, the need for bone grafts, and/or the need for implant exchanges had statistically superior HRQoL outcomes than those who did require intervention within one year after initial tibial fracture nailing. Conclusion. We identified several baseline patient factors, surgical factors, and post-intervention procedures within one year after intramedullary nailing of a tibial shaft fracture that may influence a patient’s HRQoL.

Māori consistently have poorer health outcomes compared to non-Māori within Aotearoa. Numerous worldwide studies demonstrate that ethnic minorities receive less analgesia for acute pain management. We aimed to compare analgesic management of a common orthopaedic injury, tibial shaft fracture, between Māori and non-Māori. A retrospective cohort study from January 1. st. , 2015, to December 31. st. 2020 inclusive. Eligible patients were 16–65 years old and had isolated closed tibial shaft fractures. 104 patients were included in the study, 48 Māori and 56 Non-Māori. Baseline demographics were similar between the 2 cohorts. The primary outcome measure was type of analgesia charted on the ward. Secondary outcome measures were pre-hospital medications given, pain scores on arrival to the emergency department (ED) and the ward, time to analgesia in ED and type of analgesia given in ED. Statistics were calculated using Fisher's exact test, Pearson's chi-squared test or Wilcoxson's rank sum test as appropriate. No statistically significant differences were found in opiates or synthetics charted to Māori vs Non-Māori (83% vs 89% and 77% vs 88% respectively), opiates given in ED, time to analgesia in ED or ED and ward arrival pain scores. Of statistical significance is that Māori were less likely to receive pre-hospital medication compared to Non-Māori (54% vs 80% respectively, p=0.004). Māori were significantly less likely to receive pre-hospital pain medication compared to Non-Māori. However no other statistically significant findings were found when comparing pain scores, time to analgesia or type of pain relief charted for Māori vs non-Māori. The reasons for Māori receiving significantly less prehospital medication were not explored in this study and further investigation is required to reduce the bias that exists in this area

Open or closed fracture of the tibial shaft is a common injury. There is no long-term outcome data of patients after tibial shaft fracture utilising modern treatment methods. This study assessed pain and function of 1509 consecutive patients with a tibial shaft fracture at 12–22 years following injury. Secondary outcomes included: effect on employment, effect of social deprivation, necessity for hardware removal and comparative morbidity following fasciotomy. Prospective study of 1509 consecutive adult patients with a tibial shaft fracture (1990–1999) at a high-volume trauma unit. 1034 were male, and the mean age at injury was 40 years. Fractures were classified according to AO, and open fractures graded after Gustillo and Anderson. Time to fracture union, complication rate, hardware removal and incidence of anterior knee pain were recorded. Employment and assessment of social deprivation were detailed. Function was assessed at 12 to 22 years post injury using the Short Musculoskeletal Functional Assessment and Short Form 12 questionnaires. 87% of fractures united without further intervention. Social deprivation was associated with higher incidence of fracture and poorer functional and economic outcomes. 11.5% patients underwent fasciotomy which correlated with poorer long-term outcome. Tibial shaft fracture had high mortality in the elderly. At long-term follow-up 25% of patients have anterior knee pain and 20% ankle discomfort after IM nailing. This is the largest and longest study assessing functional and economic outcomes of tibial shaft fracture. This is the first paper to describe ankle pain following tibial IM nailing at long-term follow-up

Motorcycle accident-related traffic accidents contribute significantly to the burden of orthopaedic injuries seen in the South African Healthcare system. Subsequent to the Covid-19 pandemic, there has been an increase in the number of delivery drivers on the roads of South Africa. Many of these delivery drivers have no formal employment contracts. We aim to describe the demographics and injury patterns in motorcyclists involved in time dependent delivery work in South Africa; and to quantify the cost to the state of their orthopaedic surgeries. We performed a consecutive case series study at all of the hospitals draining the study region over the period of one year. Epidemiological, clinical and cost to hospital data was collected from medical records, digital radiographs, theatre invoices and a dedicated patient questionnaire. Provisional. So far 41 delivery drivers were captured by the study over a period of 11 months. All drivers were male and the vast majority foreign nationals. 11 patients were polytraumatised and 5 required admission to an intensive care unit. The most common injury patterns were closed femur fractures (17) followed by tibial shaft fractures (13). The average cost of surgery was R35 049 and average cost of ward stay R44 882 at an average of 10 days admission in a general ward. Overall, an estimated total of R 3.1 million rand was spent on these injuries. Informally employed “app users” performing delivery work on motorcycles in South Africa have added a significant burden to the cost of state healthcare since 2020. The vast majority of these patients are foreign nationals who do not hold South African licences or health insurance. They are sustaining high energy injuries typical of motorcycle-car accidents and many of them are left with lifelong loss of function

The aim of this study was to perform a systematic review of the literature on Gustilo-Anderson (GA) type IIIB open tibial shaft (AO-42) injuries to determine the consistency of reporting in the literature. A search of PubMed, EMBASE and Cochrane Central Register of Controlled Trials was performed to identify relevant studies published from January 2000 to January 2021 using the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. The study was registered using the PROSPERO International prospective register of systematic reviews. Patient/injury demographics, management and outcome reporting were recorded. There were 32 studies that met the inclusion criteria with a total of 1,947 patients (70.3% male, 29.7% female). There were 6 studies (18.8%) studies that reported on comorbidities and smoking, with mechanism of injury reported in 22 (68.8%). No studies reported on all operative criteria included, with only three studies (9.4%) reporting for time to antibiotics, 14 studies (43.8%) for time from injury to debridement and nine studies (28.1%) for time to definitive fixation. All studies reported on the rate of deep infection, with a high proportion documenting union rate (26/32, 81.3%). However, only two studies reported on mortality or on other post-operative complications (2/32, 6.3%). Only 12 studies (37.5%) provided any patient reported outcomes. This study has demonstrated a deficiency and a lack of standardized variable and outcome reporting in the orthopaedic literature for Gustilo-Anderson type IIIB open tibial shaft fractures. We propose a future international collaborative Delphi process is needed to standardize

Virtual mechanical testing is a method for measuring bone healing using finite element models built from computed tomography (CT) scans. Previously, we validated a dual-zone material model for ovine fracture callus that differentiates between mineralized woven bone and soft tissue based on radiodensity. 1. The objective of this study was to translate the dual-zone material model from sheep to two important clinical scenarios: human tibial fractures in early-stage healing and late-stage nonunions. CT scans for N = 19 tibial shaft fractures were obtained prospectively at 12 weeks post-op. A second group of N = 33 tibial nonunions with CT scans were retrospectively identified. The modeling techniques were based on our published method. 2. The dual-zone material model was implemented for humans by performing a cutoff sweep for both the 12-week and nonunion groups. Virtual torsional rigidity (VTR) was calculated as VTR = ML/φ [N-m. 2. /°], where M is the moment reaction, L is the diaphyseal segment length, and φ is the angle of twist. As the soft tissue cutoff was increased, the rigidity of the clinical fractures decreased and soft tissue located within the fracture gaps produced higher strains that are not predicted without the dual zone approach. The structural integrity of the nonunions varied, ranging from very low rigidities in atrophic cases to very high rigidities in highly calcified hypertrophic cases, even with dual-zone material modeling. Human fracture calluses are heterogeneous, comprising of woven bone and interstitial soft tissue. Use of a dual-zone callus material model may be instrumental in identifying delayed unions during early healing when callus formation is minimal and/or predominantly fibrous with little mineralization.

Aims. The study objective was to prospectively assess clinical outcomes for a pilot cohort of tibial shaft fractures treated with a new tibial nailing system that produces controlled axial interfragmentary micromotion. The hypothesis was that axial micromotion enhances fracture healing compared to static interlocking. Methods. Patients were treated in a single level I trauma centre over a 2.5-year period. Group allocation was not randomized; both the micromotion nail and standard-of-care static locking nails (control group) were commercially available and selected at the discretion of the treating surgeons. Injury risk levels were quantified using the Nonunion Risk Determination (NURD) score. Radiological healing was assessed until 24 weeks or clinical union. Low-dose CT scans were acquired at 12 weeks and virtual mechanical testing was performed to objectively assess structural bone healing. Results. A total of 37 micromotion patients and 46 control patients were evaluated. There were no significant differences between groups in terms of age, sex, the proportion of open fractures, or NURD score. There were no nonunions (0%) in the micromotion group versus five (11%) in the control group. The proportion of fractures united was significantly higher in the micromotion group compared to control at 12 weeks (54% vs 30% united; p = 0.043), 18 weeks (81% vs 59%; p = 0.034), and 24 weeks (97% vs 74%; p = 0.005). Structural bone healing scores as assessed by CT scans tended to be higher with micromotion compared to control and this difference reached significance in patients who had biological comorbidities such as smoking. Conclusion. In this pilot study, micromotion fixation was associated with improved healing compared to standard tibial nailing. Further prospective clinical studies will be needed to assess the strength and generalizability of any potential benefits of micromotion fixation. Cite this article: Bone Jt Open 2021;2(10):825–833

Abstract. Objectives. The need to accurately forecast the injury burden has never been higher. With an aging, ever expanding trauma population and less than half of the beds available compared to 1990, the National Health Service (NHS) is stretched to breaking point1,2. Resultantly, we aimed to determine whether it is possible to predict the proportionality of injuries treated operatively within orthopaedic departments based on their number of Neck of Femur fracture (NOF) patients reported both in our study and the National Hip Fracture Database (NHFD). Methods. We utilised the ORthopaedic trauma hospital outcomes - Patient operative delays (ORTHOPOD) dataset of 22,585 trauma patients across the four countries of the United Kingdom (UK) admitted to 83 hospitals between 22/08/22 – 16/10/22. This dataset had two arms: arm one was assessing the caseload and theatre capacity, arm two assessed the patient, injury and management demographics. Results. Our results complied with the data reported to the NHFD in over 80% of cases for both the 2022 and five-year average reported numbers. More operations were performed for elderly hip fractures alone than for the combined totals of the next four most common fractures: ankle, distal radius, tibial shaft and forearm (6387 vs 5922). Conversely, 10 out of the 13 fracture types were not encountered by at least one hospital and 93% of hospitals encountered less than 2 fractures of a certain type.60% of trauma is treated within Trauma Units (TUs) however, per unit, Major Trauma Centres (MTCs) treat approximately 43% more patients. Similarly, 11 out of the 14 fracture types examined presented more frequently to a MTC however 3 of the most common fractures had a preponderance for TUs (elderly hip, distal radius and forearm fractures). After excluding NOF, lower limb fractures accounted for approximately 57% of fractures in all countries and ankle and distal radius fracture combined comprised more than 50% in 74% of regions. There were few outliers across the study regarding number of fractures treated by a hospital with tibial shaft fractures demonstrating the highest number of outliers with 4. Conclusions. The number of hip fractures seen on average by an individual unit remains relatively consistent as does the regional variation of any given fracture; resultantly, it is possible to predict injury proportionality based off a unit's hip fracture numbers. This powerful tool could transform both resource allocation and recruitment. Declaration of Interest.

The study was designed to determine the incidence and to quantify the risk factors of permanently decreased bone mineral density (BMD) of the Lumbar spine and Femoral neck following tibial shaft fractures. 42 consecutive adults treated for isolated tibial shaft fractures at our institution between January 1984 and June 1985 formed the subjects of this study. Mechanism and type of injury, method of treatment, length of immobilisation and weight bearing status and healing time were determined from the patient records. A questionnaire including history of smoking, alcohol consumption, medications, other fractures, medical conditions like thyroid/parathyroid disorders, convulsions, and renal disorders was administered. Bone mineral density of lumbar 1–4 vertebrae and both hips was assessed using DEXA scanning. T and Z scores were generated. Statistical analysis was performed using the Chi square test to test the significance of association of osteopenia/osteoporosis (Z score < -1) with a previous tibial shaft fracture and calculating the odds ratio (OR) and 95% confidence interval (CI) to quantify the suspected risk factors. The incidence of significant loss of BMD of the ipsilateral femur and/or lumbar spine was found to be 33%. A statistically significant association (p< 0.001) between a history of tibial shaft fracture and permanent loss of BMD was noted. The following risk factors were found to be statistically significant; Smoking (OR 22, 95% CI=4–> 40, p< 0.001), Alcohol more than 20 units/week (OR 11, 95% CI 2.2–54,p< 0.005), Open fracture (OR 17, 95% CI=2.9–> 40, p< 0.001), Non-weight bearing more than 12 weeks (OR 15, 95% CI 2.9–> 40, p< 0.005), and delayed union defined as healing time more than 6 months (OR 15, 95% CI 1.54–> 40, p < 0.05). Permanent regional osteopaenia/osteoporosis occurs in a significant proportion of tibial shaft fracture patients. Modern fracture management should include identifying ‘at risk’ patients and appropriate management to prevent fragility fractures

Delayed union and non-union are complications of fracture healing associated with pain and with functional and psychosocial disability. This study compares the effect on self-reported health outcomes of delayed union or non-union of femoral and tibial shaft fractures treated at two major metropolitan trauma centres in Victoria. Patients admitted to the Royal Melbourne Hospital and The Alfred with extra- articular femoral and tibial shaft fractures during 2003-2004 and 2005-2006, and followed up by the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR) were included. Hospital medical records were reviewed to identify the outcome of each fracture. Fracture healing was assessed by the need for unplanned revision surgery for delayed union or nonunion, and clinical and radiological evidence of union. Prospectively-gathered VOTOR health outcome measurements included the Short Form 12-Item Health Survey (SF-12), and return to work and pain status at 6 and 12 months post injury. Of the 520 patients, 260 femoral and 282 tibial shaft fractures were included. In total, 285 fractures progressed to union, 138 fractures developed delayed union or non-union and 119 fractures had an unknown outcome. Factors that were significantly different between the union and delayed union or non-union groups included: fund source, mechanism of injury, other injuries, wound and Gustilo type, and fixation method. On linear regression modelling, an inverse relationship was demonstrated between delayed union or nonunion and the Physical and Mental Component Summary scores of the SF-12. This was statistically significant at both 6 and 12 months post injury unadjusted and adjusted for age, gender and other injuries. On logistic regression modelling, patients with delayed union or non-union showed unadjusted and adjusted risk ratios of 0.85 and 0.82, respectively at 6 months, and 0.82 and 0.76, respectively at 12 months to return to work. Similarly, patients with delayed union or nonunion had unadjusted and adjusted risk ratios of 1.09 and 1.11, respectively at 6 months, and 1.33 and 1.37, respectively at 12 months to have pain. Both were statistically significant at 12 months post injury unadjusted and adjusted for age, gender and other injuries. Patients with delayed union or non-union of femoral and tibial shaft fractures have poorer physical and mental health at 6 and 12 months post injury. In addition, they are less likely to have returned to work and more likely to still have pain at 12 months post injury

Introduction. Fracture related infections (FRI) following intramedullary nailing for tibial shaft fractures remain challenging to treat with associated high patient morbidity and healthcare costs. Recently, antibiotic-coated nails have been introduced as a strategy to reduce implant related infection rates in high-risk patients. We present the largest single-centre case series on ETN PROtect® outcomes reporting on fracture union, infection rates and treatment complications. Materials and Methods. 56 adult patients underwent surgery with ETN PROtect® between 01/09/17 and 31/12/20. Indications consisted of acute open fractures and complex revision cases (FRI, non-union surgery and re-fracture) with a mean of 3 prior surgical interventions. 51 patients had an open fracture as their index injury. We report on patient characteristics and outcomes including radiological/clinical union and deep infection. The one-year minimum follow-up rate was 87.5%. Results. One (1.8%) patient developed a deep surgical infection and associated non-union requiring further surgery. In addition, we identified three cases (5.4%) of aseptic non-union following facture treatment with ETN PROtect®. Of the 5 patients who underwent staged complex revision surgery for established FRI with ETN PROtect®, all had treatment failure with ongoing symptoms of deep infection requiring further treatment. Conclusions. Use of the ETN PROtect® nail in high-risk patients in the acute trauma setting demonstrates promising outcomes in the prevention of implant-related infection. In our limited series we have failed to observe any benefit over uncoated nails, when used in treating cases of established FRI/osteomyelitis and would therefore advise caution in their use, especially in view of the high cost

Abstract. Background. With the increasingly accepted method of suprapatellar tibial nailing for tibial shaft fractures, we aimed to compare intraoperative and postoperative outcomes of infrapatellar (IP) vs suprapatellar (SP) tibial nails. Methods. A retrospective cohort analysis of 58 patients. 34 SP tibial nails over 3 years versus 24 IP tibial nails over a similar time frame. We compared; radiation exposure, patient positioning time (PPT), non-union rate and follow-up time. Knee pain in the SP group was evaluated, utilising the Hospital for Special Surgery (HSS) Knee injury and Osteoarthritis outcome score (KOOS). Results. 58 patients with a mean age of 43 years were included. Mean intraoperative radiation dose for SP nails was 61.78cGy (range 11.60 to 156.01cGy) vs 121.09cGy (range 58.01 to 18.03cGy) for IP nails (p < 0.05). Mean PPT for SP nails was 10 minutes vs 18 minutes for IP nails (p < 0.05). All fractures united in the SP group vs one non-union in the IP group. Mean follow-up was 5.5 months vs 11 months in the SP and IP group respectively. Mean KOOS was 7 (range 0 to 22) at 6 months for the SP group. Conclusion. The semi extended position (SP group) leads to reduced radiation exposure because of ease of imaging. All Patients in the SP group showed improved outcomes, with shorter follow-up and fracture union. The KOOS revealed SP nail patients had minimal pain and good knee function. This study establishes a management and PROMs baseline for ongoing evaluation of SP nails

The frequent choice of treatment for tibial shaft fractures is intramedullary nailing. However there are cases where this treatment is problematic and alternative treatments are chosen with satisfied results. Twenty-nine patients with complex, unstable tibial shaft fractures (13 males and 16 females) aged 18 to 76 years (mean age 49 years) were treated using Ilizarov external fixation, the last decade in our Department by the same surgeon. The indications were open Gustillo III fractures, comminuted fractures of the proximal or distal third tibia near metaphysis, concomitant plateau or pillon fractures and fractures after total knee arthroplasty (TKA). All frames were applied the first day of injury. Patients without concomitant intraarticular fracture or bone deficit allowed to full weight bearing within2 weeks after surgery. Union and good to excellent alignment with full range of motion in the knee and ankle joints was obtained in all patients. Three patients needed bone lengthening using the initial applied frame after corticotomy in second operation. There were 7 delayed unions in fractures without bone deficit, 10 superficial pin tract infection treated with antibiotics and local care and 1 deep infection which needed surgical intervention. Ilizarov external fixation gives the solution in difficult and problematic tibial shaft fractures and allows early weight bearing

Introduction: the choice of treatment for tibial shaft fractures in adults is intramedullary nailing. However there are cases where this treatment is problematic and alternative treatments are chosen. Patients and Methods: 29 patients with unstable tibial shaft fractures (13 males and 16 females; aged 18 to 76 years) were treated using Ilizarov technique, last decade, by the authors. The indications were open fractures type III Gustillo, comminuted fractures of the proximal or distal third near metaphysis, concomitant plateau or pillon fractures and fractures after TNR. All frames were applied the first day of injury. Patients without concomitant intraarticular fracture or bone deficit allowed to full weight bearing within two weeks after surgery. Results: union and good to excellent alignment with full range of motion in the knee and ankle joints was obtained in all patients. Three patients needed bone lengthening using the initial applied frame after corticotomy in second operation. There were 7 delayed unions in fractures without bone deficit. As complications there were superficial pin tract infection in 10 patients treated with antibiotics and local care and one deep infection which needed surgical intervention. Conclusions: Ilizarov technique gives the solution in difficult and problematic tibial shaft fractures and allows early weight bearing
