Plating Versus Intramedullary Nailing of OTA/AO 43C1 and C2 Intra-articular Distal Tibia Fractures: A Propensity Score and Multivariate Analysis.

OBJECTIVE: To compare rates of reduction loss, nonunion, and infection in intra-articular distal tibia fractures (IADTF) treated with limited open reduction internal fixation and intramedullary nailing (IMN) as compared to open reduction internal fixation with plate and screws (plate fixation [PF]). DESIGN: Retrospective review. SETTING: Level-I academic trauma center. PATIENT SELECTION CRITERIA: Patients age ≥ 18 with OTA/AO 43C1 and C2 IADTF treated with IMN or PF between 2013-2021. OUTCOME MEASURES AND COMPARISONS: Loss of reduction, surgical site infection (SSI), nonunion, and patient-reported outcomes (PROs) were compared for IMN versus PF treatments. RESULTS: One hundred ten patients met the inclusion criteria (IMN 33 and PF 77). There was no loss of reduction found. Seventeen nonunions (15% overall; IMN 4/33 and PF 13/77) and 13 SSIs (12% overall; IMN 2/33 and PF11/77) were identified. Despite several risk factors being identified for nonunion and SSI in bivariate analysis, only open fracture remained significant as a risk factor for both nonunion (odds ratio 0.09 for closed fracture, 95% confidence interval, 0.02-0.56, P = 0.009) and SSI (odds ratio 0.07 for closed fracture, 95% confidence interval, 0.06-0.26, P = 0.012) in the multivariate model. Propensity scoring based on presurgical variables was significantly different between patients who received IMN versus PF ( P = 0.03); however, logistic regression incorporating the propensity score revealed no significant association with nonunion and SSI. Adjusting for the propensity score, there remained no association comparing IMN versus PF with nonunion and SSI ( P = 0.54 and P = 0.17, respectively). There was also no difference in PROs between IMN and PF (physical function: P = 0.25 and pain interference: P = 0.21). CONCLUSIONS: Overall nonunion and SSI prevalence was 15% and 12%, respectively, in operatively treated OTA/AO 43C1 and C2 IADTF. An open fracture was a significant risk factor for nonunion and SSI. Metaphyseal fixation through IMN or PF did not affect loss of reduction, nonunion, SSI, or PROs. LEVEL OF EVIDENCE: Therapeutic Level III.

Improved Outcomes in Distal Tibial Non-Union: A Retrospective Study of 8 Patients Treated with Distal Tibial Nail and Screw Fixation.

BACKGROUND Non-union of distal tibia fractures is a challenge in orthopedic surgery and can be due to open fractures, osteopenia, infection, or failure of surgical devices. This retrospective study aimed to describe 8 patients with non-union of distal tibial fractures treated with distal tibial nail and screw fixation. MATERIAL AND METHODS According to the Gustilo-Anderson classification, 3 patients had type 2 open fractures, 1 had a type 3 open fracture, 1 had a type 1 open fracture, and 3 had closed fractures. The Association of Osteosynthesis AO classified 4 patients as A2, 2 as B2, and 2 as C2. Seven patients received distal supporting bolt-locking-screw nails (DSBLS) and 1 received DSBLS nail and plate in their most recent operation. Clinical outcomes were evaluated with American Orthopaedic Foot and Ankle Society (AOFAS) and Olerud-Molander scores. RESULTS All 8 patients were male, with a mean age of 35.5±14.6 years. Six patients had atrophic non-union, 1 had hypertrophic non-union, and 1 had infected non-union. Union was achieved in all patients. The average union time was 25.1 (range, 12-60) months, and the follow-up duration was 3.6 (range, 2-6) years. The mean Olerud-Molander score was 92.5 (range 85-100), and the mean AOFAS score was 91.2 (range, 85-100). There was no evidence of rotational deformity or shortening. CONCLUSIONS Distal tibial non-unions benefit from nails with DSBLS system due to their excellent biomechanical properties. These nails facilitate union and allow patients to bear weight early in the postoperative period, enabling a quicker return to normal activities.

Single institution retrospective study evaluating the frequency of implant removal and associated risk factors following open fracture fixation in 80 cases (2010-2020).

BACKGROUND: Open fractures occur commonly in small animals and are characterised by contamination of the fracture site. While never quantified, it is believed that open fractures stabilised with internal implants are at a higher risk for requiring explantation. This retrospective study determines the frequency and risk factors for explantation following use of internal fixation. Medical records of client-owned dogs and cats with an open fracture, between 2010 and 2020 stabilised using internal implants, were included. Data retrieved included signalment, cause and characterisation of the fracture, comorbidities, preexisting infections, and all details related to anesthesia and surgery. Pre-, Peri- and post-operative antibiotic use were detailed. All cases were followed to clinical union. Postoperative complications, including requirement for implant removal were recorded and classified as major or minor. Associations between potential risk factors and need for explantation were assessed. RESULTS: Of 80 cases, 72 (90%) were dogs and eight (10%) cats. Major complications were encountered in 23 (28.75%) cases and minor complications in 16 (20%) cases. Explantation was performed in 17 cases (21.25%). Out of 72 dogs, 13 required explantation (18%) whereas four of the eight cats needed implants removed (50%). Only diagnosis of postoperative infection was associated with an increased risk of explantation (RR 2.77; 95% CI 1.25; 6.15; p = 0.045). CONCLUSION: Approximately 1 in 5 open fractures stabilised using internal fixation can be anticipated to require explantation, with cats potentially being at a higher risk than dogs. Cases diagnosed with postoperative infection are at a higher risk for requiring implant removal.

Safety of Prepping the External Fixator In Situ During Staged Internal Fixation of Pilon Fractures: A Retrospective Comparative Cohort Study.

OBJECTIVE: (1) To assess the rate of fracture-related infection (FRI) and unplanned reoperation of disinfecting and prepping in the external fixator (Ex-Fix) instrument during definitive open reduction and internal fixation (ORIF) of pilon fractures treated by a staged protocol and (2) to determine whether the amount of time from external fixation to ORIF influences the risk of FRI. DESIGN: Retrospective cohort study. SETTING: Level 1 academic trauma center. PATIENTS: One hundred thirty-three patients who underwent operative treatment for pilon fracture between 2010 and 2020. INTERVENTION: External fixation and ORIF with or without the Ex-Fix prepped in situ during definitive fixation. MAIN OUTCOME MEASUREMENTS: FRI and unplanned reoperation rates. RESULTS: 133 patients were enrolled, of which 47 (35.3%) had Ex-Fix elements prepped in situ. There was an overall infection rate of 23.3% and unplanned reoperation rate of 11.3%, and there was no significant difference in rates between the 2 cohorts. Patients with Ex-Fix elements prepped in situ who developed an FRI had a higher rate of MRSA and MSSA . Diabetes ( P = 0.0019), open fracture ( P = 0.0014), and longer (≥30 days) interval to ORIF ( P = 0.0001) were associated with postoperative FRI. CONCLUSIONS: Prepping elements of the Ex-Fix in situ did not lead to an increase in rates of FRI or unplanned reoperation. Although diabetes and open fracture were associated with FRI risk, a stronger association was a longer interval of Ex-Fix utilization before definitive internal fixation, specifically 30 days or greater.

Butterfly fragments in diaphyseal tibial fractures heal unpredictably: Should we be adopting other strategies for these high risk fractures?

INTRODUCTION: The natural history of diaphyseal tibial butterfly fragments is poorly documented. Numerous studies have analyzed risk factors for nonunions in the tibial shaft with known factors including Gustilo classification, ASA class, and cortical contact. However, the healing potential and ideal management of nonsegmental butterfly fragments in this setting remains unknown. The aim of this study was to determine the nonunion rate of diaphyseal tibial fractures with a butterfly fragment. METHODS: A performed a retrospective review of patients at a single academic Level 1 Trauma Center from 2000-2020 who underwent intramedullary nailing of tibial shaft fractures. Those with non-segmental butterfly fragments (OTA/AO: 42-B) and minimum 12 month follow up were included. Morphologic measurements of butterfly fragments were performed to measure location, size, and displacement, and mRust scores at final follow up were calculated. Outcome measures were surgery to promote union, and mRust scores. RESULTS: A total of 99 patients were included with 21 patients requiring revision surgery to promote union. Thirty six patients had open fractures and 77% of patients were male with a mean age of 34 (range: 12-80). Average follow up was 19 months (3 months - 12 years). The most common location of the butterfly fragment was the anterior cortex (42%), with a mean length of 7.8cm (SD: 3.3) and width of 1.8cm (SD: 0.5cm). At final follow-up 37% of fractures had persistent lucency without callus at the site of the butterfly while only 31% of fractures had remodeled cortex. Average time to complete healing was 13.3 months. Open fractures with butterfly fragments were more likely to go on to nonunion than closed (44% vs 9.2%, p=<0.001). The length of the butterfly fragment was not different between the union and nonunion groups (7.7 vs 7.5, P=0.42). CONCLUSIONS: Open tibial shaft fractures with a butterfly fragment have a high risk of nonunion. Further research may seek to determine if adjunct treatment of butterfly fragments (ie inter-fragmentary compression) in the acute setting could improve healing rates.

Epidemiology, Etiology, Timing and Severity of Open Fracture - a Five Years Review From a Tertiary Trauma Center, Eastern Province, Saudi Arabia.

Background: Open fractures are severe injuries resulting from the bone breaking through the skin, and they have a negative impact on patients' physical, mental, and financial well-being as well as that of the healthcare system. The incidence of open fractures varies globally. These injuries can lead to prolonged disability, increased healthcare costs, and psychological distress. The Gustilo-Anderson classification system is used to classify open fractures into three categories which surgeons use as an index for the severity of an injury and as a prognostic tool. Management involves a multidisciplinary approach, focusing on preventing infection, promoting wound healing, and restoring function. Objective: The objective of this study is to provide statistics on the epidemiology of open fractures presented to the emergency department to be used later to create management protocols. Methods: This 5-year retrospective observational analysis of open fracture patients at King Fahad Hospital, a tertiary trauma care institute in Alkhobar from 2018-2023, aimed to understand socio-demographics, injury mechanisms, fracture patterns, and timing. Data were collected electronically, and found 373 cases which were reviewed, and only 138 open fractures fit our inclusion and exclusion criteria and were added to the study. Results: The study analyzed 138 openly fractured bones in 132 patients aged 2 to 68. Most bones affected were in the lower extremities, the most common being the forefoot bones. The most common mode of injury was a motorbike, followed by MVA. The most common Gustilo type was type 2, with no significant correlation between gender and severity. Musculoskeletal system injury was the highest associated system. Furthermore, we observe a slight increase in cases in Winter/Fall weather seasons. Conclusion: Total amount of 84.8% of patients with open fractures are men, compared to 15.2% of women. The average age of patients is 25.6 ± 15.6 years. Motorbike accidents, then MVA, are the two leading causes of open fractures. Weather seasons, especially in fall and winter, may also contribute to an increase in open fractures. We found that type 2 is the most common Gustilo type among the injured bones (59.1%).

Soft tissue complications following extensile lateral compared with minimally invasive surgical approaches in the operative treatment of calcaneus fractures.

BACKGROUND: Extensile lateral (ELA) and minimally invasive surgical (MIS) approaches are commonly used in the operative fixation of calcaneus fractures. The ELA has been the standard of care, but is associated with a high risk of wound complications. Minimally invasive surgical approaches have been developed to reduce these complications. METHODS: We completed a retrospective chart review of 201 patients with calcaneus fractures repaired by either ELA or MIS approaches between 2011 and 2018. We compared the incidence of soft tissue complications, including wound infections (requiring no surgical treatment) and deep infections (requiring surgical intervention), and performed multivariate regression analysis to determine independent risk factors associated with soft tissue complications and reoperation. RESULTS: The overall incidence of soft tissue complications was 8.1% in the MIS group compared with 28.8% in the ELA group (p = 0.0004). The incidence of patients with a deep infection requiring reoperation was 4.7% in the MIS group compared with 19.2% in the ELA group (p = 0.003). Risk factors of soft tissue complications included the presence of an open fracture (odds ratio [OR] 11.59, 95% confidence intervals [CI] 3.25-44.25) and use of ELA (OR 4.22, 95% CI 1.67-10.90). Risk factors for a deep infection requiring reoperation included the use of ELA (OR 4.43, 95% CI 1.51-13.64) and the presence of an open fracture (OR 4.00, 95% CI 0.91-15.3). CONCLUSION: The ELA is associated with an increased incidence of soft tissue complications and reoperation when compared with the MIS approach. The ELA and open fractures were found to be independent risk factors of soft tissue complications and reoperation. Surgeons treating calcaneus fractures should consider using a MIS technique, provided they are able to achieve the goals of surgical management without the ELA.

Incidence and quality of care for open fractures in England between 2008 and 2019 : a cohort study using data collected by the Trauma Audit and Research Network.

AIMS: This study estimated trends in incidence of open fractures and the adherence to clinical standards for open fracture care in England. METHODS: Longitudinal data collected by the Trauma Audit and Research Network were used to identify 38,347 patients with open fractures, and a subgroup of 12,170 with severe open fractures of the tibia, between 2008 and 2019 in England. Incidence rates per 100,000 person-years and 95% confidence intervals were calculated. Clinical care was compared with the British Orthopaedic Association Standards for Trauma and National Major Trauma Centre audit standards. RESULTS: In total, 60% of all open fractures occurred in males; the median age was 48 years (interquartile range (IQR) 29 to 68). Between 2012 and 2019, the overall incidence in England was 6.94 per 100,000 person-years. In males, the highest incidence observed was in those aged 20 to 29 years (11.50 per 100,000 person-years); in females, incidence increased with age, peaking at 32.11/100,000 person-years at 90 years of age and over. Among those with severe open fractures of the tibia, there was a bimodal distribution in males, peaking at 20 to 29 years (3.71/100,000 person-years) and greater than 90 years of age (2.84/100,000 person-years) respectively; among females, incidence increased with age to a peak of 9.91/100,000 person years at 90 years of age and over. There has been variable improvement with time in the clinical care standards for patients with severe open fractures of the tibia. The median time to debridement was 13.0 hours (IQR 6.4 to 20.9); almost two-thirds of patients underwent definitive soft-tissue coverage within 72 hours from 2016 to 2019. CONCLUSION: This is the first time the incidence of all open fractures has been studied using data from a national audit in England. While most open fractures occurred in young males, the incidence increased with age in females to a much greater level than observed in older males. The degree of missing data in the national audit is startling, and limits the certainty of inferences drawn concerning open fracture care. Cite this article: Bone Joint J 2022;104-B(6):736-746.

Open ankle fractures: Factors influencing unplanned reoperation.

INTRODUCTION: Ankle fractures are amongst the most common open fracture injuries presenting to major trauma centres (MTC) and their management remains a topic of debate. Incidence is increasing particularly in the elderly population however the optimal surgical approach and risk factors for unplanned reoperation remain scarce. We therefore conducted a retrospective case study to analyse our institution's outcomes as well as identify risk factors for early unplanned reoperation. MATERIALS AND METHODS: Sixty-five consecutive open ankle fractures were identified using our institutional database between July 2016 and July 2020. Medical records and operation notes were reviewed to identify patient age at injury, Sex, co-morbidities and other co-morbidities, fracture configuration, extent of soft tissue injury, fixation type and post-operative complications. The data was categorised into four groups for analysis, 1) age, 2) AO-OTA classification 3) Sex 4) Gustilo-Anderson grade. Statistical analysis was undertaken to identify predictors of unplanned reoperation. RESULTS: The mean age of patients at the time of injury was 60.8. Unplanned reoperation rate was 17.5%. Age and Gustilo-Anderson classification grade were both statistically significant predictors of unplanned reoperation. AO-OTA classification, Sex and Diabetes were not statistically significant factors associated with unplanned reoperation. CONCLUSION: Age and quality of soft tissue envelope are significant risk factors for unplanned reoperation. Patients with these risk factors may benefit from an alternative surgical approach.

The injury characteristics of open pilon fractures predictive of complications.

OBJECTIVE: Determine predictive injury factors for wound complications in open pilon fractures (OTA/AO 43B and 43C). DESIGN: Retrospective Case Series. SETTING: Level I Trauma Center. PATIENTS/PARTICIPANTS: A total of 61 open pilon fractures in 60 patients were evaluated after meeting inclusion and exclusion criteria. INTERVENTION: The majority of injuries underwent a staged protocol with immediate antibiotics, debridement, irrigation and external fixation. Following soft tissue stabilization, internal fixation was performed and wound closure achieved in a coordinated fashion depending on the type of closure required. MAIN OUTCOME MEASUREMENTS: Early amputation rate, 90-day major (wound dehiscence or deep infection requiring operative intervention) and minor (superficial infection) wound complications. RESULTS: Four patients incurred early amputations, 11 had major wound complications and 5 had minor wound complications. An early amputation was more likely if they presented with an OTA Open Fracture Classification (OTA-OFC) Bone Loss Grade 3. A major wound complication was more likely if they presented with a fall from > 3 m, a multifragmentary articular surface, a segmental fibula fracture, or an OTA-OFC Contamination Grade 3. A multifragmentary articular surface was also predictive of developing any wound complication. CONCLUSIONS: Open pilon fractures are severe, limb-threatening injuries and are at risk for wound complications. Patients presenting with these injuries and a predictive factor should be counseled regarding the possibility of early limb loss or experiencing a wound complication that will require additional treatment. LEVEL OF EVIDENCE: Level III.

What Are the Risk Factors for Infection After Operative Treatment of Peritalar Fracture Dislocations?

OBJECTIVE: To assess the risk factors associated with deep infection after operative treatment of peritalar fracture dislocations. DESIGN: A retrospective study was performed to identify patients who had operative treatment of a peritalar fracture dislocation over an 11-year period (2008-2019). SETTING: Level 1 trauma center. PARTICIPANTS: Patients were identified by review of all surgical billing that included open reduction of peritalar dislocation. Minimum follow-up for inclusion was 3 months or the outcome of interest. A total of 178 patients were identified, and 154 patients met inclusion criteria. MAIN OUTCOME: The primary outcome was deep infection, defined as return to the operating room for debridement with positive cultures. RESULTS: A total of 19 (12.3%) patients developed a postoperative deep infection. The most common associated fractures were talus (47%), calcaneus (33%), and fibula (9%) fractures. The infected group was significantly older (47.2 vs. 39.5 years, P = 0.03). Patients undergoing operative management for peritalar fracture dislocations with current smoking were found to have significantly higher odds of postoperative deep infection (74 vs. 34%, adjusted odds ratio = 7.4, 95% confidence interval, 2.3-24.1, P = 0.001). There was a significantly higher risk of infection in patients with a Gustilo-Anderson type 3 open fracture (32 vs. 12%, adjusted odds ratio = 5.7, 95% confidence interval, 1.6-20.3, P = 0.007). The infected group had high rates of below knee amputation when compared with the group without infection (47 vs. 1%, P < 0.001). CONCLUSION: In our retrospective study, risk factors for infection after peritalar fracture dislocation included older age, smoking, and Gustilo-Anderson type 3 open fracture. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Effect of Tourniquet Use During Surgical Treatment of Open Fractures.

BACKGROUND: We sought to evaluate whether tourniquet use, with the resultant ischemia and reperfusion, during surgical treatment of an open lower-extremity fracture was associated with an increased risk of complications. METHODS: This is a retrospective cohort study of 1,351 patients who had an open lower-extremity fracture at or distal to the proximal aspect of the tibia and who participated in the FLOW (Fluid Lavage of Open Wounds) trial. The independent variable was intraoperative tourniquet use, and the primary outcome measures were adjudicated unplanned reoperation within 1 year of the injury and adjudicated nonoperative wound complications. RESULTS: Unplanned reoperation and nonoperative wound complications were roughly even between the no-tourniquet (18.7% and 19.1%, respectively) and tourniquet groups (17.8% and 20.8%) (p = 0.78 and p = 0.52). Following matching, as determined by model interactions, tourniquet use was a significant predictor of unplanned reoperation in Gustilo Type-IIIA (odds ratio, 3.60; 95% confidence interval, 1.16 to 11.78) and IIIB fractures (odds ratio, 16.61; 95% confidence interval, 2.15 to 355.40). CONCLUSIONS: The present study showed that tourniquet use did not influence the likelihood of complications following surgical treatment of an open lower-extremity fracture. However, in cases of severe open fractures, tourniquet use was associated with increased odds of unplanned reoperation; surgeons should be cautious with regard to tourniquet use in this setting. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

The effect of COVID-19 on a Major Trauma Network. An analysis of mechanism of injury pattern, referral load and operative case-mix.

PURPOSE: The aim of this study was to evaluate changes in both mechanism and diagnoses of injuries presenting to the orthopaedic department during this lockdown period, as well as to observe any changes in operative case-mix during this time. METHODS: A study period of twelve weeks following the introduction of the nationwide "lockdown period", March 23rd - June 14th, 2020 was identified and compared to the same time period in 2019 as a "baseline period". A retrospective analysis of all emergency orthopaedic referrals and surgical procedures performed during these time frames was undertaken. All data was collected and screened using the 'eTrauma' management platform (Open Medical, UK). The study included data from a five NHS Foundation Trusts within North West London. A total of 6695 referrals were included for analysis. RESULTS: The total number of referrals received during the lockdown period fell by 35.3% (n=2631) compared to the same period in 2019 (n=4064). Falls remained proportionally the most common mechanism of injury across all age groups in both time periods. The proportion sports related injuries compared to the overall number of injuries fell significantly during the lockdown period (p<0.001), however, the proportion of pushbike related accidents increased significantly (p<0.001). The total number of operations performed during the lockdown period fell by 38.8% (n=1046) during lockdown (n=1732). The proportion of patients undergoing operative intervention for Neck of Femur (NOF) and ankle fractures remained similar during both study periods. A more non-operative approach was seen in the management of wrist fractures, with 41.4% of injuries undergoing an operation during the lockdown period compared to 58.6% at baseline (p<0.001). CONCLUSION: In conclusion, the nationwide lockdown has led to a decrease in emergency orthopaedic referrals and procedure numbers. There has been a change in mechanism of injuries, with fewer sporting injuries, conversely, there has been an increase in the number of pushbike or scooter related injuries during the lockdown period. NOF fractures remained at similar levels to the previous year. There was a change in strategy for managing distal radius fractures with more fractures being treated non-operatively.

Analysis of machete cut fractures in Nigerian civilian trauma setting.

Machete cut fracture is an important component of morbidity associated with machete injuries although it is under reported. This was a retrospective study to assess machete cut fractures in patients seen in Federal Teaching Hospital Abakaliki and National Orthopaedic Hospital Enugu from 2009 to 2018. There were 91 patients with 154 fractures, male- to- female ratio was 10:1 and mean age was 31.6 ± 14.6 years. The aetiological factors were assault (57, 62.6%), armed robbery (29, 31.9%) and accidental injury (5, 5.5%). The three top bones involved were ulna, metacarpal and finger-phalanx. Fracture was communited in (17, 11.0%), and Gustilo Anderson grade IIIC in (22, 14.3%). Injury to hospital arrival interval later than 6 h was common and correlated with prolonged length of hospital stay (p < 0.001). Anaemia, wound infection and hemorrhagic shock were the three top complications. Nine (5.8%) fractures ended in extremity amputation. Eleven (12.1%) patients left against medical advice, and 5 (5.5%) were transferred. Normal union in 98.3% of the fractures treated and followed up for a minimum of one year. Case fatality rate was 2.2%; none of the patient that died had pre hospital care, and hemorrhagic shock accounted for all the mortality. These call for appropriate injury preventive mechanisms, and improved rates of early presentation of patients to hospital, and pre hospital care.

Compound elevated fracture-reconstruction of an unusual skull injury.

Our institute of Legal Medicine was asked to examine a 27-year-old patient admitted to the neurosurgical department after a non-fatal accident (non-observed fall from height) at a construction site. Forensic advice was needed because of unexplainable injuries. By example of this case of a near-to-impalement, we would like to highlight an unusual, clinically frequently forgotten, and forensically thus far not discussed type of skull fracture with outward dislocation of bone fragment(s). These so-called compound elevated fractures of the skull are described occasionally in, mainly neurosurgical, case reports. Knowing its entity and its pathomechanism may be of forensic interest, particularly in order of reconstruction purpose. This article provides a brief review of the literature with special regard to the pathomechanism. In addition, it demonstrates the possible pitfall of computed tomography, or more specifically, the 3D reconstruction. To our knowledge, this is the first forensic report describing this kind of fracture.

The Orthopaedic Trauma Society classification of open fractures.

AIMS: To describe a new objective classification for open fractures of the lower limb and to correlate the classification with patient-centred outcomes. METHODS: The proposed classification was investigated within a cohort of adults with open fractures of the lower limb who were recruited as part of two large clinical trials within the UK Major Trauma Network. The classification was correlated with patient-reported Disability Rating Index (DRI) and EuroQol five-dimension questionnaire (EQ-5D) health-related quality of life in the year after injury, and with deep infection at 30 days, according to the Centers for Disease Control and Prevention definition of a deep surgical site infection. RESULTS: A total of 748 participants were included in the analysis. Of these, 288 (38.5%) had a simple open fracture and 460 (61.5%) had a complex fracture as defined by the new classification system. At 12 months, the mean DRI in the simple fracture group was 32.5 (SD 26.8) versus 43.9 (SD 26.1) in the complex fracture group (odds ratio (OR) 8.19; 95% confidence interval (CI) 3.69 to 12.69). At 12 months the mean health-related quality of life (EQ-5D utility) in the simple fracture group was 0.59 (SD 0.29) versus 0.56 (SD 0.32) in the complex fracture group (OR -0.03; 95% CI -0.09 to 0.02). The differences in the rate of deep infection at 30 days was not statistically significant. CONCLUSION: The Orthopaedic Trauma Society open fracture classification is based upon objective descriptors of the injury and correlates with patient-centred outcomes in a large cohort of open fractures of the lower limb.

Pediatric tibial shaft and distal metaphyseal fractures.

OBJECTIVES: This study aims to investigate the effects of associated factors like age, fracture level, accompanying fibular fractures and wound condition on healing by determining and comparing union scores of pediatric tibial fractures (PTFs). PATIENTS AND METHODS: Forty-five patients with 46 PTFs (32 males, 13 females; mean age 9.5 years; range 2 to 16 years) who were treated by closed reduction and casting or operated between January 2016 and January 2019 were retrospectively evaluated. The union scores were evaluated at the end of fourth, sixth and eighth weeks and compared to each other. Effects of the age, associated fibular fractures, wound condition, fracture level and treatment type to union score were analyzed. RESULTS: Twenty-eight (60.9%) out of 46 PTFs had associated fibular fractures and 18 (39.1%) did not. Motor vehicle accident was the most frequent etiologic factor (47.8%). Thirty-four out of 46 fractures were closed tibial fractures (73.9%) and 12 had open wound (26.1%). There was a negative correlation between age and the union scores (p<0.001 for each week). No significant difference was observed between the union score of diaphyseal and metaphyseal fractures at the fourth, sixth, and eighth weeks. The union scores of each week were higher in the conservative group compared to operative group (p<0.001 for each week). Associated fibular fracture group had lower union scores compared to isolated tibial fracture group at fourth, sixth and eighth weeks. Likewise, the union scores of the open fracture group were lower than the closed fracture group (p<0.05 for each week). CONCLUSION: Associated fibular fractures, open fractures and aging negatively affect union scores of PTFs. Attention should be paid, particularly in these conditions, during the selection of the operation type and the follow-up period of PTFs.

Analysing outcomes through orthopaedic trauma registry - A prospective cohort study.

OBJECTIVE: To develop a registry for recording injury-specific data to identify gaps and improve care. Methods: The prospective cohort study was conducted at Aga Khan University Hospital, Karachi, from June 2015 to July 2018 though enrollment of patients with limb trauma is continuing to date. Data on injuries and management related to Tibia shaft fractures was collected from medical records, and outcomes were assessed on follow-up visits. Internationally validated injury-specific scores were utilised for assessing functional, clinical and radiological outcomes. SPSS version 19 was used for data analysis. Results: There were 763 patients with 825 limb injuries. Of the injuries, 310(37.6%) related to upper limbs and 515(62.4%) to the lower limbs. Management was surgical for 741(89.9%) and conservative for 84(10.1%) injuries. Overall, 12(1.57%) patients died, and in 7(0.91%) cases mortality was unrelated to trauma and its management. There were 105 patients with tibia shaft fractures. Of them, 88(83.8%) were males and 17(16.2%) were females. At one-year follow-up excellent-to-good results were 12(92%) for intramedullary nailing followed by 7(78%) for open reduction and internal fixation. Conclusion: Registry data can be used to develop preventive strategies and to improve management protocols.

Combined treatment with vacuum sealing drainage, TopClosure device, and Ilizarov technique for traumatic hemipelvectomy: A rare case report of successful repairing of large-size soft tissue defects.

RATIONALE: Traumatic hemipelvectomy is a rare but lethal catastrophic injury. PATIENT CONCERNS: A case of a very young child with open fracture of left sacroiliac joint dislocation and pubic symphysis diastasis, suffered from a severe large-size soft tissue defects. DIAGNOSIS: Traumatic hemipelvectomy. INTERVENTIONS: Complete amputation was performed and three kinds of surgical techniques including regulated negative pressure-assisted wound therapy (RNPT), TopClosure device, and Ilizarov technique were jointly utilized to secure closure in the further revisions of the soft tissue injury and reconstruct reconstructive surgery. OUTCOMES: Six months after hospital discharge, the patient was able to ambulate with a single limb and a prosthesis and she is independent in many activities of daily living currently. LESSONS: We report this case to share experience with other clinicians in the management of this deadly extensive defects after traumatic hemipelvectomy in patients.

Open Talus Fractures: Early Infection and Its Epidemiological Characteristics.

Open talus fractures are relatively rare and severe open injuries with a high risk of severe infection. To better understand the epidemiological characteristics of this kind of injury, a monocentric case review was conducted among open talus fracture patients admitted in West China Hospital of Sichuan University between January 2010 and December 2014. Fifty-one (N = 51) patients were recruited to the study, including 44 (86.3%) males and 7 (13.7%) females. Fifty-two cases of open talus fractures were diagnosed among the patients (1 patient had bilateral fractures). The primary cause of open talus fracture was a fall from a height. The rate of concurrent injuries associated with open talus fracture was 84.3%. The overall infection rate was 41.2%, rising with the increase of injury severity classified by Gustilo-Anderson classification and the existence of peritalar dislocation. Therefore, it can be concluded that open talus fractures are at high risk of concurrent complications and early infection. It is necessary to perform a complete physical examination to search for possible concurrent injuries. When evaluating the risk of infection, in addition to the severity of open talus fracture, the existence and severity of peritalar dislocation should also be taken into consideration.
