Unstable pelvic fractures in women: implications on obstetric outcome. INTERNATIONAL ORTHOPAEDICS 2024; 48:235-241. [PMID: 37710070 PMCID: PMC10766730 DOI: 10.1007/s00264-023-05979-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Accepted: 09/06/2023] [Indexed: 09/16/2023]
Abstract
PURPOSE Obstetric outcomes in women following pelvic injuries requiring surgical fixation is not thoroughly known. We aimed to evaluate if radiographic measurements (RMs) can be used to provide information on delivery methods outcome after these injuries, and to evaluate if metal work removal is required prior to delivery. METHOD A retrospective study in a level 1 trauma centre of female patients with pelvic fractures treated operatively, aged 16-45 at the time of injury. Participants completed a questionnaire regarding their obstetric history. RM evaluating pelvic symmetry, displacement, and pelvimetry were conducted on postoperative radiographs and CT scans. Patients who gave birth after the injury were divided to two groups according to the delivery method: vaginal delivery (VD) and caesarean section (CS). These two groups RM were compared. RESULTS Forty-four patients were included, comparison of the RM of patients who delivered by CS (9) and patients who had only VD (11) showed no significant difference between the groups. Two patients underwent a trial of VD who subsequently underwent urgent CS due to prolonged labour, their RM were below the average and their pelvimetry measurements were above the cut-off for CS recommendation. Eleven patients had uncomplicated VD, all had retained sacroiliac screws at the time of delivery and one patient had an anterior pubic plate. CONCLUSION Postoperative RM did not show an effect on delivery method of women after pelvic fracture fixation. A relatively high number of patients who underwent normal vaginal delivery had retained sacroiliac screws. These findings can form the foundation for larger cohort studies.

Abstract
OBJECTIVES The purpose of this study was to investigate the safety and early clinical results from the use of a novel, noble metal-coated titanium tibial nail for the definite stabilization of tibial shaft fractures at risk of developing complications. DESIGN This is a retrospective case series with prospectively collected data. SETTING Level I Trauma Centre in the United Kingdom. PATIENTS AND INTERVENTION Thirty-one patients who were managed with the Bactiguard-coated Natural Nail and achieved a minimum of a 12-month follow-up. MAIN OUTCOME MEASUREMENTS The main outcomes of this study were the incidence of adverse events (related to implant safety), complications (particularly infection), and reinterventions. RESULTS Thirty-one patients with a mean age of 41.6 years were included in this study. Active heavy smokers or intravenous drug users were 25.8% and 9.7% of them were diabetic. Five fractures were open while 13 had concomitant soft-tissue involvement (Tscherne grade 1 or 2). Twenty-seven patients healed with no further intervention in a mean time of 3.3 months. Three patients developed nonunion and required further intervention. The overall union rate was 96.7%. One patient developed deep infection after union (infection incidence 3.2%). Six patients (6/31; [19.3%]) required reinterventions [2 for the treatment of nonunion, 3 for removal of screws soft-tissue irritation, and 1 for the management of infection). CONCLUSIONS The management of tibial shaft fractures with a noble metal-coated titanium tibial nail demonstrates encouraging outcomes. Further studies are desirable to gather more evidence in the performance of this innovative implant. LEVEL OF EVIDENCE Therapeutic Level IV.

Abstract
Segmental femoral fractures represent a rare but complex clinical challenge. They mostly result from high-energy mechanisms, dictate a careful initial assessment and are managed with various techniques. These often include an initial phase of damage control orthopaedics while the initial manoeuvres of patient and soft tissue resuscitation are employed. Definitive fixation consists of either single-implant (reconstruction femoral nails) or dual-implant constructs. There is no consensus in favour of one of these two strategies. At present, there is no high-quality comparative evidence between the various methods of treatment. The development of advanced design nailing and plating systems has offered fixation constructs with improved characteristics. A comprehensive review of the existing evidence with a step-by-step description of these different definitive fixation strategies based on three case examples was conducted. Furthermore, the rationale for using single vs dual-implant strategy in its case is presented with supportive references. The prevention of complications relies mainly on the strict adherence to basic principles of fracture fixation with an emphasis on careful preoperative planning, the quality of the reduction, and the application of soft tissue-friendly surgical methods.

Abstract
Management of severely injured patients remains a challenge, characterised by a number of advances in clinical practice over the last decades. This evolution refers to all different phases of patient treatment from prehospital to the long-term rehabilitation of the survivors. The spectrum of injuries and their severity is quite extensive, which dictates a clear understanding of the existing nomenclature. What is defined nowadays as polytrauma or major trauma, together with other essential terms used in the orthopaedic trauma literature, is described in this instructional review. Furthermore, an analysis of contemporary management strategies (early total care (ETG), damage control orthopaedics (DCO), early appropriate care (EAC), safe definitive surgery (SDS), prompt individualised safe management (PRISM) and musculoskeletal temporary surgery (MuST)) advocated over the last two decades is presented. A focused description of new methods and techniques that have been introduced in clinical practice recently in all different phases of trauma management will also be presented. As the understanding of trauma pathophysiology and subsequently the clinical practice continuously evolves, as the means of scientific interaction and exchange of knowledge improves dramatically, observing different standards between different healthcare systems and geographic regions remains problematic. Positive impact on the survivorship rates and decrease in disability can only be achieved with teamwork training on technical and non-technical skills, as well as with efficient use of the available resources.

Abstract
The ability to enhance fracture healing is paramount in modern orthopaedic trauma, particularly in the management of challenging cases including peri-prosthetic fractures, non-union and acute bone loss. Materials utilised in enhancing fracture healing should ideally be osteogenic, osteoinductive, osteoconductive, and facilitate vascular in-growth. Autologous bone graft remains the gold standard, providing all of these qualities. Limitations to this technique include low graft volume and donor site morbidity, with alternative techniques including the use of allograft or xenograft. Artificial scaffolds can provide an osteoconductive construct, however fail to provide an osteoinductive stimulus, and frequently have poor mechanical properties. Recombinant bone morphogenetic proteins can provide an osteoinductive stimulus; however, their licencing is limited and larger studies are required to clarify their role. For recalcitricant non-unions or high-risk cases, the use of composite graft combining the above techniques provides the highest chances of successfully achieving bony union.

Abstract
Lately, the care of severely injured patients in the United Kingdom has undergone a significant transformation. The establishment of regional trauma networks (RTN) with designated Major Trauma Centers (MTCs) and satellite hospitals called Trauma Units (TUs) has centralized the care of severely injured patients in the MTCs. Pelvic fractures are notoriously linked with hypovolemic shock or even death from excessive blood loss. The aim of this prospective cohort study is to compare the profile of severely injured patients with combined pelvic fractures and their mortality between two different distinct eras of an advanced healthcare system. Anonymized consecutive patient records submitted to TARN UK between 2002 and 2017 by NHS England hospitals were analyzed. Records of patients without a pelvic fracture, or with isolated pelvic fractures (no other serious injury with abbreviated injury scale AIS >2) were excluded. All patients with known outcomes were included and were divided into 2 distinct periods (pre-RTN era: between January 2002 and March 2008 (control group); and RTN era April 2013 to June 2017 (study group)). Data from the transition period from April 2008 to March 2013 were excluded to minimize the effect of variations between the developing networks and MTCs during that era. Overall, the study group included 10,641 patients, whereas the control group was 3152 patients, with a median age of 52.4 and 35.1 years and an ISS of 24 and 27 respectively. A systolic blood pressure below 90mmHg was observed in 7.2% of patients in the study group and 10.4% in the control group. A significant increase of the median time to death (from 8hrs to 188hrs) was observed between the two eras. The cumulative mortality of severely injured patients with pelvic fractures decreased significantly from 17.8% to 12.4% (p<0.0001). The recorded improvement of survivorship in the subgroup of severely injured patients with a pelvic fracture (32% lower in the post-RTN than in the pre-RTN period: OR 1.32 (95% CI 1.21 - 1.44), following the first 5 years of established regional trauma networks in NHS England, is encouraging, and should be attributed to a wide range of factors that translate to all levels of trauma care.

Incidence, risk factors and potential timing of occurrence of pulmonary embolism in fatal trauma: An autopsy based case-control study on 2705 victims. Surgeon 2023; 21:8-15.

Abstract
BACKGROUND Pulmonary embolism (PE) following trauma is a potentially preventable but highly lethal complication. We sought to investigate the incidence, risk factors and potential timing of occurrence of post-traumatic PE in a large cohort of trauma fatalities. METHODS A case-control study on 9266 consecutive trauma fatalities (between 1996 and 2005) from a regional autopsy-based trauma registry. Injuries were classified according to the Abbreviated Injury Scale-1990 edition (AIS-90) and the Injury Severity Score (ISS) was calculated. Hospitalized victims were categorized according to the presence or absence of PE on autopsy. Univariate comparisons and multivariate logistic regression analysis for probabilities of association (odds ratios-OR) were performed. RESULTS Out of 2705 subjects who met the inclusion criteria, 116 had autopsy findings of PE and constituted the PE group (incidence of 4,3%), while the remaining victims formed the control group. The survival time of the PE group ranged from 0.66 to 104.73 days. Victims in the PE group were older (median age 69.5 vs 59), had lower ISS values (median 16 vs 26) and longer post-injury survival times (median 13.6 vs 5.7 days). Positively associated risk factors were AIS2-5 pelvic ring injuries (OR:2.23) and secondary deaths following an uneventful hospital discharge (OR:3.97), while AIS2-5 head (OR:0.33) and abdominal injuries (OR:0.23) showed a reverse association. CONCLUSIONS Trauma fatalities with autopsy findings of PE were associated with less severe trauma indicating that PE was likely detrimental to the fatal outcome. Both the early and delayed occurrence of PE was reaffirmed. Prophylactic measures should be initiated promptly and extended post discharge for high risk patients to prevent secondary deaths.

Abstract
Infected post-traumatic femoral defects are challenging to treat, and limited options exist. The case of a 20-year-old polytrauma male who sustained a segmental femur fracture involving the femoral neck, distal femur and an intermediate diaphyseal bone defect of 12 cm is presented. The patient declined a long-term frame in his femur. The 2-stage Masquelet procedure resulted in successful outcome with limb preservation. Femoral bone defects are challenging to treat. Patients do not tolerate bone transport well in this area. Successful management of a 12cm femoral bone defect is reported in a 20-year old patient using the Masquelet technique.

Abstract
Biofilm represents an organized multicellular community of bacteria having a complex 3D structure, formed by bacterial cells and their self-produced extracellular matrix. It usually attaches to any foreign body or fixation implant. It acts as a physical protective barrier of the bacteria from the penetration of antibodies, bacteriophages, granulocytes and biocides, antiseptics, and antibiotics. Biofilm-related infections will increase in the near future. This group of surgical site infections is the most difficult to diagnose, to suppress, to eradicate, and in general to manage. Multispecialty teams involved in all stages of care are an effective way to improve results and save resources and time for the benefit of patients and the health system. Significant steps have occurred recently in the prevention and development of clever tools that we can employ in this everlasting fight with the bacteria. Herein, we attempt to describe the nature and role of the "biofilm" to the specific clinical setting of surgical site infections in the field of orthopaedic trauma surgery.

Abstract
The Vancouver classification is still a useful tool of communication and stratification of periprosthetic fractures, but besides the three parameters it considers, clinicians should also assess additional factors. Combined advanced trauma and arthroplasty skills must be available in departments managing these complex injuries. Preoperative confirmation of the THA (total hip arthroplasty) stability is sometimes challenging. The most reliable method remains intraoperative assessment during surgical exploration of the hip joint. Certain B1 fractures will benefit from revision surgery, whilst some B2 fractures can be effectively managed with osteosynthesis, especially in frail patients. Less invasive osteosynthesis, balanced plate–bone constructs, composite implant solutions, together with an appropriate reduction of the limb axis, rotation and length are critical for a successful fixation and uneventful fracture healing.

Abstract
Pelvic girdle pain (PGP) refers specifically to musculoskeletal pain localised to the pelvic ring and can be present at its anterior and/or posterior aspects. Causes such as trauma, infection and pregnancy have been well-established, while patients with hypermobile joints are at greater risk of developing PGP. Research exploring this association is limited and of varying quality. In the present study we report on the incidence, pathophysiology, diagnostic and treatment modalities for PGP in patients suffering from Hypermobility Spectrum Disorder (HSD) and Hypermobility-Type Ehlers-Danlos Syndrome (hEDS). Recommendations are made for clinical practice by elaborating on screening, diagnosis and management of such patients to provide a holistic approach to their care. It appears that this cohort of patients are at greater risk particularly of mental health issues. Moreover over, they may require a multidisciplinary approach for their management. Ongoing research is still required to expand our understanding of the relationship between PGP, HSD and hEDS by appropriately diagnosing patients using the latest updated terminologies and by conducting randomised control trials to compare outcomes of interventions using standardised patient reported outcome measures.

Abstract
Aims To analyse the learning points from the first 30 days of the COVID-19 lockdown at our institution. Patients & methods Following ethical approval, data were collected prospectively on all patients admitted under orthopaedics between March 23, 2020, and April 22, 2020. This included baseline demographics (sex, age), biochemical (blood tests), radiological (chest X-ray (CXR), computed tomography (CT)), nature and mechanism of injury, comorbidities, regular medication, observations, specific respiratory symptoms of COVID-19, management, operations, time to theatre, and outcome including mortality incidence. The nature of injury and operations performed were compared to the same period of the previous year (2019). Results During the study period, 162 (74 males) patients were admitted, with a mean age of 60.7 (range 1-101, SD 2.1). On admission, 66 (41%) patients were tested for COVID, out of which eight (13.7%) patients tested positive. Subsequently, another four patients tested positive, who developed symptoms after admission. Four out 12 (33%) confirmed COVID patients died. During this period, 4/150 other patients also died of other causes (mortality incidence 2.6%). The average ages of COVID non-survivors vs survivors were 88, SD 1, vs 76, SD 12, respectively; 2/4 had concurrent diabetes and cancer, another cancer alone, and another complex autoimmune disease managed by immunosuppressive medication. Overall admissions significantly reduced by almost 50% compared with the previous year (162 vs 373, p=<0.05), including cases of polytrauma (15 vs 33). Time to surgery was increased by an average of one day, mainly due to time taken for COVID-19 swab results to come back, and in positive patients, this was an average of 2.75 days (0-13). Lymphopenia was a useful biomarker of COVID, with levels significantly different between groups (p=<0.05). Of the clinical symptoms assessed, 8/12 patients experienced positive chest symptoms or pyrexia but only four had positive CXR changes. Discussion & lessons learnt Eight out of 12 patients who contracted COVID-19 survived without needing intensive care. Non-survivors were older with significant comorbidities. Lymphopenia is a good biomarker of the disease, but suspicious CXR was not sensitive for excluding it. Trauma volume reduced. We have highlighted significant changes to expect should there be a second wave of the virus. Key lessons learnt were that reduction in trauma volume and cessation of elective operating allowed for redeployment, including taking over the minor injury unit; more senior, consultant decision-makers 'at the front door' reduced unnecessary admissions. Increased use of conservative practice was effective at reducing operations required. Expedited COVID swab test processing allowed early de-escalation of isolation, reducing time to surgery. We expect approximately 12% of the typical orthopaedic population to be admitted with COVID, and up to 33% of these patients to die within 28 days of contracting the virus. The vast majority of patients, however, can be managed appropriately with ward-level care. An early decision on escalation and resuscitation status in the emergency department improves patient flow significantly. Remote working was effective and could be extended in the future. We have highlighted the significant changes to expect should there be a second wave of the virus and effective solutions for managing the problems that arise, which could be useful for other units.

Abstract
Sacral fractures are a heterogeneous group of fractures occurring in young people following road traffic accidents and falls from height, or in the elderly with osteoporosis following trivial trauma.This heterogeneity, combined with the low incidence of sacral fractures, determines a lack of experience amongst physicians, often leading to misdiagnosis, underestimation and inadequate treatment. The diagnosis should be made by assessing specific features during the clinical presentation, while computed tomography (CT) scan continues to be the choice of investigation.Sacral fractures can be treated non-operatively or surgically. Non-operative treatment is based on rest, pain relief therapy and early mobilization as tolerated. Surgical techniques can be split into two main groups: posterior pelvic fixation techniques and lumbopelvic fixation techniques. Anterior pelvic fixation techniques should be considered when sacral fractures are associated with anterior pelvic ring injuries, in order to increase stability and reduce the risk of posterior implant failure. To improve fracture reduction, different solutions could be adopted, including special positioning of the patient, manipulation techniques and use of specific reduction tools. Patients suffering from spinopelvic dissociation with associated neurologic lesions hardly ever recover completely, with residual lower-limb neurologic sequelae, urinary problems and sexual disfunction.Herein, we present issues, challenges and solutions related to the management of sacral fractures.

Abstract
INTRODUCTION The ilioinguinal approach is the standard approach for the open reduction and internal fixation of the majority of displaced, anteriorly based acetabular fractures as it offers wide access to the acetabulum, is extensile, and has been associated with enhanced recovery. INDICATIONS & CONTRAINDICATIONS STEP 1 PREOPERATIVE PLANNING Review the patient's general condition and imaging studies and plan the sequence of reduction and fixation. STEP 2 PREPARATION AND PATIENT POSITIONING Position the patient supine on the fracture table, induce anesthesia, prepare the surgical field, administer intravenous antibiotics, and apply traction. STEP 3 ILIOINGUINAL APPROACH Make a long curvilinear incision over the affected lower flank, develop the 3 working windows, and reduce and stabilize the fracture while protecting the neurovascular structures and the bladder (Video 2). STEP 4 FRACTURE REDUCTION AND FIXATION For reduction of a both-column acetabular fracture, connect the mobile parts of the acetabulum to the iliac segment that is attached to the sacrum, noting that, in most cases, the usual sequence involves the reduction of the anterior column to the intact ilium followed by the reduction of the posterior column (Video 7). STEP 5 WOUND CLOSURE AND POSTOPERATIVE AFTERCARE Perform meticulous hemostasis, apply drains, and ensure watertight closure, which are the final steps of the operation (Video 8). RESULTS The ilioinguinal approach remains 1 of the standard approaches for the management of acetabular fractures10. PITFALLS & CHALLENGES

Abstract
Introduction The Kocher-Langenbeck approach is the workhorse for the reduction and fixation of hip fractures that require fixation via a posterior approach1,2. Indications & Contraindications Step 1 Preoperative Planning Review the patient's general condition and imaging studies, plan the sequence of reduction and fixation, and make sure that all of the necessary equipment is available. Step 2 Preparation and Patient Positioning Induce anesthesia, administer intravenous antibiotics as per local hospital protocol, apply antiembolism stockings, and insert a Foley catheter to the bladder. Step 3 Kocher-Langenbeck Approach Make an incision that is 15 to 20 cm long and has 2 parts (proximal and distal), which are centered over the greater trochanter. Step 4 Fracture Reduction and Fixation The reconstruction of posteriorly based fractures depends on the specific fracture type, and the goal is to provide stable column fixation and anatomical reconstruction of the acetabular articular surface, with column fixation performed before the reconstruction of the posterior wall. Step 5 Wound Closure and Postoperative Care Meticulous hemostasis, application of drains, and watertight closure are the final steps of the operation. Results The Kocher-Langenbeck approach is the workhorse for the surgical management of acetabular fractures and provides sufficient access to the majority of posterior based acetabular fractures15.

Reliability of the classification of proximal femur fractures: Does clinical experience matter? Injury 2018; 49:819-823.

Abstract
BACKGROUND Radiographic fracture classification helps with research on prognosis and treatment. AO/OTA classification into fracture type has shown to be reliable, but further classification of fractures into subgroups reduces the interobserver agreement and takes a considerable amount of practice and experience in order to master. QUESTIONS/PURPOSES We assessed: (1) differences between more and less experienced trauma surgeons based on hip fractures treated per year, years of experience, and the percentage of their time dedicated to trauma, (2) differences in the interobserver agreement between classification into fracture type, group, and subgroup, and (3) differences in the interobserver agreement when assessing fracture stability compared to classifying fractures into type, group and subgroup. METHODS This study used the Science of Variation Group to measure factors associated with variation in interobserver agreement on classification of proximal femur fractures according to the AO/OTA classification on radiographs. We selected 30 anteroposterior radiographs from 1061 patients aged 55 years or older with an isolated fracture of the proximal femur, with a spectrum of fracture types proportional to the full database. To measure the interobserver agreement the Fleiss' kappa was determined and bootstrapping (resamples = 1000) was used to calculate the standard error, z statistic, and 95% confidence intervals. We compared the Kappa values of surgeons with more experience to less experienced surgeons. RESULTS There were no statistically significant differences in the Kappa values on each classification level (type, group, subgroup) between more and less experienced surgeons. When all surgeons were combined into one group, the interobserver reliability was the greatest for classifying the fractures into type (kappa, 0.90; 95% CI, 0.83 to 0.97; p < 0.001), reflecting almost perfect agreement. When comparing the kappa values between classes (type, group, subgroup), we found statistically significant differences between each class. Substantial agreement was found in the clinically relevant groups stable/unstable trochanteric, displaced/non-displaced femoral neck, and femoral head fractures (kappa, 0.60; 95% CI, 0.53 to 0.67, p < 0.001). CONCLUSIONS This study adds to a growing body of evidence that relatively simple distinctions are more reliable and that this is independent of surgeon experience.

Abstract
PURPOSE Surgical costs are under scrutiny and surgeons are being held increasingly responsible for cost containment. In some instances, implants are the largest component of total procedure cost, yet previous studies reveal that surgeons' knowledge of implant prices is poor. Our study aims to (1) understand drivers behind implant selection and (2) assess whether educating surgeons about implant costs affects implant selection. METHODS We surveyed 226 orthopedic surgeons across 6 continents. The survey presented 8 clinical cases of upper extremity fractures with history, radiographs, and implant options. Surgeons were randomized to receive either a version with each implant's average selling price ("price-aware" group), or a version without prices ("price-naïve" group). Surgeons selected a surgical implant and ranked factors affecting implant choice. Descriptive statistics and univariate, multivariable, and subgroup analyses were performed. RESULTS For cases offering implants within the same class (eg, volar locking plates), price-awareness reduced implant cost by 9% to 11%. When offered different models of distal radius volar locking plates, 25% of price-naïve surgeons selected the most expensive plate compared with only 7% of price-aware surgeons. For cases offering different classes of implants (eg, plate vs external fixator), there was no difference in implant choice between price-aware and price-naïve surgeons. Familiarity with the implant was the most common reason for choosing an implant in both groups (35% vs 46%). Price-aware surgeons were more likely to rank cost as a factor (29% vs 21%). CONCLUSIONS Price awareness significantly influences surgeons' choice of a specific model within the same implant class. Merely including prices with a list of implants leads surgeons to select less expensive implants. This implies that an untapped opportunity exists to reduce surgical expenditures simply by enhancing surgeons' cost awareness. TYPE OF STUDY/LEVEL OF EVIDENCE Economic/Decision Analyses I.

Implementation of a standardized protocol to manage elderly patients with low energy pelvic fractures: can service improvement be expected? INTERNATIONAL ORTHOPAEDICS 2017; 41:1813-1824. [PMID: 28733846 DOI: 10.1007/s00264-017-3567-2] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/16/2017] [Accepted: 06/30/2017] [Indexed: 12/13/2022]
Abstract
PURPOSE The incidence of low energy pelvic fractures (FPFs) in the elderly is increasing. Comorbidities, decreased bone-quality, problematic fracture fixation and poor compliance represent some of their specific difficulties. In the absence of uniform management, a standard operating procedure (SOP) was introduced to our unit, aiming to improve the quality of services provided to these patients. METHODS A cohort study was contacted to test the impact of (1) using a specific clinical algorithm and (2) using different antiosteoporotic drugs. Multivariate regression analysis was used to determine prognostic factors. Study endpoints were the time-to-healing, length-of-stay, return to pre-injury mobility, union status, mortality and complications. RESULTS A total of 132 elderly patients (≥65 years) admitted during the period 2012-2014 with FPFs were enrolled. High-energy fractures, acetabular fractures, associated trauma affecting mobility, pathological pelvic lesions and operated FPFs were used as exclusion criteria. The majority of included patients were females (108/132; 81.8%), and the mean age was 85.8 years (range 67-108). Use of antiosteoporotics was associated with a shorter time of healing (p = 0.036). Patients treated according to the algorithm showed a significant protection against malunion (p < 0.001). Also, adherence to the algorithm allowed more patients to return to their pre-injury mobility status (p = 0.039). CONCLUSIONS The use of antiosteoporotic medication in elderly patients with fragility pelvic fractures was associated with faster healing, whilst the adherence to a structured clinical pathway led to less malunions and non-unions and return to pre-injury mobility state.

Abstract
Intramedullary nailing, as the gold standard stabilisation method of most long bones, has been tailed by its extensive use as the basic tool of investigating the immune response to trauma in many large and small animal models, as well as at the clinical setting. Over the last few decades a complex map of interactions between pro and anti-inflammatory pathways has been the result of these significant global research efforts. Parallel to the evolution of modern nailing and reaming techniques, significant developments at the fields of other disciplines relevant to trauma care, has improved the contemporary management of injured patients, challenging previous concepts and altering clinical barriers. The current article aims to summarise the current understanding of the effect of instrumenting the medullary canal after trauma, and hint on potential future directions.

The use of external fixators in the definitive stabilisation of the pelvis in polytrauma patients: Safety, efficacy and clinical outcomes. Injury 2017; 48:1139-1146. [PMID: 28363753 DOI: 10.1016/j.injury.2017.03.033] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2016] [Accepted: 03/22/2017] [Indexed: 02/02/2023]
Abstract
OBJECTIVES To analyse the complications and outcomes (functional/radiographic) of Pelvic External Fixators applied as part of the definitive fixation in polytrauma patients. DESIGN A single center retrospective chart review. SETTING A level-1 trauma center. PATIENTS AND METHODS We reviewed all the polytrauma patients (ISS>16) between 2007 and 2012 that had a PEF applied more than 30days. Complications including infection, aseptic loosening, neurological injury, loss of reduction, non-union and mal-union were recorded. Pelvic asymmetry and Deformity Index (DI) were measured at the immediate postoperative radiographs and final follow-up. The functional outcome at final follow up was estimated using a scale previously reported by Chiou et al. RESULTS 59 patients with mean age of 38.4 (16 - 81) years and mean ISS score 28 (16- 66) were included. The PEFs were applied for mean duration of 56 (30-104) days. The average follow-up was 403days. 22 injuries were type B and 37 type C (AO/OTA). The most common symptomatic complications were pin site infection in 11 (18.6%) and loosening in 5 (8.5%) cases. 44 (74.5%) patients had satisfactory functional outcome. The immediate post-operative and final asymmetry and DI were compared between the two pelvic injury groups (type B and C fractures). The difference in displacement progression was more for type C injuries (p=0.034) but no correlation to the functional outcome was evident. CONCLUSION PEF can be used as definitive alternative stabilization method in specific situations at polytrauma setting. Radiological displacement occurred in both type B and C injuries but the clinical outcome was not correlated to this displacement. Complications related to PEF do not affect the final clinical outcome. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
INTRODUCTION This study aimed to identify the prevalence and the risk factors for re-interventions following reamed intramedullary nailing (IMN) of tibial shaft fractures. PATIENTS AND METHODS We retrospectively analysed a prospectively populated data of adult patients that underwent reamed intramedullary nailing for stabilization of tibial shaft fractures over a period of three years. Exclusion criteria were immature patients, pathological and periarticular fractures. Data collected included patient demographics, mechanism of injury, open or closed injury pattern, ISS, perioperative complications, reintervention characteristics (time, cause, number), smoking habits, medical co-morbidities and progress to radiological fracture union. Fractures were classified according to AO/OTA system. The cohort of these patients was divided in two groups: Group 1 included the patients who healed uneventfully and Group 2 included the patients who underwent a re-intervention for the healing of the fracture. A logistic regression analysis model was used to assess the odds ratio (OR) of identified risk factors predicting the necessity of re-interventions. RESULTS 181 (129 male) patients with a mean age of 37 (range 16-87) met the inclusion criteria. 30 patients were excluded due to inadequate follow up, leaving 151 patients for the study group. 119 patients were included in Group 1. 32 (21.2%) patients who had at least one re-intervention (range 1-3) were included in Group 2. The most common causes for re-intervention were aseptic non-union (31.3%) and removal of implants due to soft tissue irritation/anterior knee pain (31.3%), followed by early metalwork failure (12.5%), infected non-union (9.4%), correction of rotational deformities (9.4%) and canal intramedullary sepsis with evident fracture healing (6.3%). 29 (25.8%) from the study cohort patients sustained an open fracture and 8 of them underwent a re-intervention (20.5% of interventions). Incidence of fracture pattern 42-B, C was statistically significant greater in the reintervention (40.6%) compared to the non-re-intervention group (23.53%) (p = 0.026). Risk factors predicting the need for re-interventions included the type of fracture B, C (p = 0.026 OR: 2.528, range: 1.117-5.721) and increased alcohol consumption (p = 0.027/OR: 2.618, range: 1.116-6.141). CONCLUSION Fracture pattern and alcohol abuse were highly predictive for re-interventions following reamed IM nailing for stabilization of acute tibial shaft fractures.

Abstract
The management of upper limb non-unions can be challenging and often with unpredictable outcomes. In this study we present our experience with the use of BMP-7 in the treatment of upper limb non-unions. Between 2004 and 2011 all consecutive patients who were treated with BMP-7 were followed up prospectively until fracture union. Fracture union was assessed with regular radiological and clinical assessment. At the final follow up clinical assessment included the short Disabilities of the Arm, Shoulder and Hand (DASH) score. The minimum follow up was 12 months (12-36). In total 42 patients met the inclusion criteria with a mean age of 47 years. Anatomical distribution of the nonunion sites included 19 cases of mid/proximal forearm, 14 humeri, 6 distal radius and 3 clavicle. 35 patients had atrophic non-union, 11 had previous open fractures, and 10 had bone loss (range 1-3 cm). The mean number of operations performed and the mean time from injury to BMP-7 application was 1.5 and 26 months, respectively. 40 fractures had both clinical and radiological union whereas 2 patients had partial radiological union but a pain free range of motion. BMP-7 was applied in isolation in 1 case and in 41 cases the application was combined with autologous bone grafting. DASH scores were available at final follow up in 23 (55%) patients with a mean of 33 score (range 2-86.4). This study supports the view that the combination of ABG and BMP-7 can be considered as a successful treatment modality for the treatment of recalcitrant upper limb non-unions. Further studies preferably randomised controlled trials are desirable to throw more light into the role of BMP-7 in the treatment of upper limb nonunions.

Abstract
This prospective study was undertaken at a regional tertiary referral centre to evaluate the results of treatment of bone defects managed with the induced membrane (IM) technique. Inclusion criteria were patients with bone defects secondary to septic non-union, chronic osteomyelitis and acute fracture with bone loss. Pathological fractures with bone loss were excluded. Data collection included patient demographics, pathology, previous surgical intervention, size of bone defect, type of graft implanted, time-to-union and complications/reinterventions. The minimum time of follow up was 12 months. Forty-three patients (32 males) met the inclusion criteria with a mean age of 47.9 years (range 18-80 years). 22 patients had an acute traumatic bone loss associated with open fracture and 21 presented with an infected non-union or underlying osteomyelitis requiring bone excision. The most common microorganisms grown were staphylcoccous aureus and coagulase negative staphylococcous. The mean length of the bone defect area was 4.2 cm (range 2-12 cm). All patients were managed with the two stage technique receiving composited grafting (Autologous bone graft (Iliac crest/RIA), graft expander as required, osteoprogenitor cells, growth factor) during the second stage. There was one failure (humeral infected non-union) in a previous background of bone radiation that necessitated reconstruction with a free fibula vascularized graft. One patient had a fall and sustained implant failure (humeral defect) 3 months after reconstruction and following re-plating progressed to union 4 months later. Two patients required re-grafting due to failure of healing in one of the defect sides. One patient presented with a discharging sinus 2 years after successful healing of a tibial defect that was treated successfully with soft tissue and bone debridement without necessitating further interventions. One patient despite union (distal 1/3 tibia) underwent a below knee amputation due to a dysfunctional ankle/foot (previous foot compartment syndrome-regional pain syndrome). Of those patients, with lower limb injuries, 4 patients had leg length discrepancies of 1 cm, 1.5 cm, 2 cm (two patients) respectively. The mean time to radiological union was 5.4 months (range 2-12 months). The average time of healing of 1 cm bone defect was 1.24 months. Patients with upper limb reconstruction recovered earlier than those with lower limb injuries. At the latest follow up all patients were able to mobilize full weight bearing without residual pain. The induced membrane technique appears to be an alternative good option for the management of large bone defects secondary to acute bone loss or infected non-unions. The incidence of re-interventions was low in this challenging cohort of patients. The technique should be considered in the surgeon's armamentarium as it is effective and is associated with a low rate of complications.

Abstract
The aim of this retrospective study with prospectively documented data was to report the clinical results of treatment of long bone non-unions using the "diamond concept". Over a 4-year period, patients that presented with a long bone non-union and were managed with the diamond conceptual framework of bone repair were evaluated. Exclusion criteria were hypertrophic, pathological, and infected non-unions. Fixation was revised as it was indicated whilst biological enhancement included the implantation of RIA graft, BMP-7 and concentrated bone marrow aspirate. Data recorded included patient demographics, initial fracture pattern and type of stabilisation, number of previous interventions, time to reoperation, time to union and functional outcome. Painless full weight bearing defined clinical union. Radiological union was defined as the presence of mature callous bridging to at least 3 bone cortices. The minimum follow up was 12 months (range 12-32). In total 64 patients (34 males) with a mean age of 45 years (17-83) were evaluated. Anatomical distribution of non-unions included the femur (54.68%), tibia (34.38%), humerus (4.68%), radius (3.13%) and clavicle (3.13%). The median number of previous interventions was 1 (range 1-5). The majority of patients (82.62%) underwent revision of fixation whereas only bone grafting was performed 9.38% of patients. Three patients developed superficial wound infection (one was MRSA), 1 had deep vein thrombosis and 1 developed heterotopic bone formation. Union was successful in 63/64 (98.4%) non-unions at a mean time of 6 months (range 3-12). All patients were mobilising pain free and returned to their daily living activities at the final follow up. The application of the "diamond concept" in this cohort of patients was associated with a high union rate by providing an optimal mechanical and biological environment. Such an approach should be considered in the surgeon's armamentarium particularly in such cases where difficulty of bone repair is foreseen.

Abstract
Contemporary fixation of the proximal femur is performed utilising a number of implants adopting different concepts and techniques. Cephalomedullary nails in particular represent one of two main options, the other being dynamic hip screw (DHS). The aim of this cohort study is to present the early experience of two large units from different countries of the use of the AFFIXUS nail for stabilisation of proximal femoral fractures. Over a period of almost three years, data from 476 proximal femoral fractures were collected and analysed using a specific research protocol, assessing data relevant to basic demographic details, in-hospital stay, surgical technique and post discharge outcomes with a minimum follow up of 6 months. Both the short and long versions of the nail were used in both centres, however, with some statistically significant differences as far as the type of fractures stabilised with the nail, which also translated to differences in the combination or not of 2 lag screws, and the static or dynamic mode of the proximal fixation construct. Other areas of difference amongst the 2 units, were the length of hospital stay and return of patients to their pre-injury residence, most likely reflecting the different social circumstances between the 2 countries. Overall mortality at a median follow up period of 17 months (range 6 to 35) was limited to 6.3%, nonunion and cut out rates 2.7%, whilst revision surgery occurred in just 2.5%. Over the first 6 months of follow up 63.6% returned to their pre-injury ambulatory status and 90.5% to their pre-injury residence. Further studies and higher level of scientific evidence is needed to verify the findings of this retrospective cohort study as to the effectiveness and safety of this new cephalomedullary nail.

Abstract
Surgical management of hip fractures in elderly people is challenging and complications relating to surgery could be devastating. They often lead to reoperation and revision surgery and can be associated with significantly increased morbidity and mortality. The most common surgical complications after internal fixation of hip fractures include cut-out, nonunion, Z-effect/medial migration, periimplant failure and avascular necrosis. High quality surgical fixation is of outmost importance to avoid surgical complications. This article presents the aetiology, risk factors and incidence of perioperative and post-fracture fixation complications. Technical tips and tricks for a successful fixation as well as the contemporary evidence surrounding the augmentation of osteoporotic bone fixation in internal fixation of hip fractures are discussed.

Abstract
The objective of this study was to report on the safety, efficacy and clinical outcomes of the Polyax Locked Plating System (Biomet, Warsaw, IN, USA) in the management of acute (non-implant related and periprosthetic) distal femoral fractures. We retrospectively reviewed 71 patients with 73 distal femoral fractures. Thirty-three of the included fractures occurred around previously placed implants. The average patients' age was 67 years (range 18-98). There were 7 early postoperative complications (9.5%) including one deep surgical site infection, 2 pulmonary embolisms and 4 urinary or respiratory infections. At final follow-up (mean 12, range 9-55 months) all fractures progressed to clinical and radiological union. However, major revision surgery for healing problems was required in 5 cases (6.8%) and minor in 3 cases (4.1%). The average time to healing was 6 (range 3-23) months. Angulation less than 5 degrees in any plane was observed in 66 cases (89.7%), within 5-10 degrees in 5 cases (7.3%) and within 10-15 degrees in 2 cases (2.9%). The mean pre-injury and final follow-up values of Glasgow Outcome Scale were 1.5(1-3) and 1.7(1-3) respectively. Overall 61 patients (83.53%) retained their pre-injury activity status. The Polyax Locked Plating System offers a safe and efficient fixation in distal femoral fractures.

Abstract
AIM: To evaluate the management, clinical outcome and cost implications of three different treatment regimes for simple elbow dislocations.
METHODS: Following institutional board approval, we performed a retrospective review of all consecutive patients treated for simple elbow dislocations in a Level I trauma centre between January 2008 and December 2010. Based on the length of elbow immobilisation (LOI), patients were divided in three groups (Group I, < 2 wk; Group II, 2-3 wk; and Group III, > 3 wk). Outcome was considered satisfactory when a patient could achieve a pain-free range of motion ≥ 100° (from 30° to 130°). The associated direct medical costs for the treatment of each patient were then calculated and analysed.
RESULTS: We identified 80 patients who met the inclusion criteria. Due to loss to follow up, 13 patients were excluded from further analysis, leaving 67 patients for the final analysis. The mean LOI was 14 d (median 15 d; range 3-43 d) with a mean duration of hospital engagement of 67 d (median 57 d; range 10-351 d). Group III (prolonged immobilisation) had a statistically significant worse outcome in comparison to Group I and II (P = 0.04 and P = 0.01 respectively); however, there was no significant difference in the outcome between groups I and II (P = 0.30). No statistically significant difference in the direct medical costs between the groups was identified.
CONCLUSION: The length of elbow immobilization doesn’t influence the medical cost; however immobilisation longer than three weeks is associated with persistent stiffness and a less satisfactory clinical outcome.

Abstract
Enhancement of healing of osteoporotic fractures remains a significant objective of contemporary clinical care. Aiming to produce preliminary clinical evidence on the effect of antiosteoporotic drugs on the process of fragility fracture healing, a pilot prospective randomized assessor-blinded trial was performed. The tested hypothesis was that it is possible to accelerate the healing of hip fractures in the presence of osteoporosis with the administration of therapeutic agents. However, significant difficulties of recruitment and completion of follow up did not allow the researchers to produce the preliminary evidence testing the study hypothesis, highlighting the challenges that contemporary clinical investigators face when conducting studies focusing on elderly patients, with high proportion of coinciding factors affecting patients' eligibility, compliance, and overall outcome. Nevertheless, the significance of enhancing bone healing in this specific patient population, dictates further clinical efforts and future well designed and funded trials of adequate power and level of evidence are desirable to allow the effective and safer management of the consequences of the modern epidemic of osteoporosis.

Abstract
PURPOSE The primary aim of this study was to report on the mid-term outcomes after quadrilateral plate reconstruction of acetabular fractures using a buttress/spring plate through an ilioinguinal approach. METHODS Between 2003 and 2011, 30 adult patients (25 males) with mean age 54 years (range 17-80) who underwent surgical fixation for an acetabular fracture and had minimum follow up of 24 months (mean 46.2, range 24-78.6) were retrospectively reviewed. Standard demographics, admission and hospitalization data (concomitant injuries, number of operative procedures, time to operating theatre, early and late complications) were correlated to the clinical (Harris Hip Score) and radiological (Matta Reduction Score and Matta Arthritis Score) outcome. RESULTS Three patients underwent a Total Hip Replacement. Functional score was excellent in 17 (56.6 %), good in 4 (13.3 %), fair in 6 (20 %) and poor in 3 (10 %) cases. Surgery-related complications included two patients with temporary lateral femoral cutaneous palsy and three with heterotopic ossification. The quality of the postoperative reduction was associated to Harris Hip Score (p = 0.015) and postoperative arthritis (p = 0.010). Strong association was evident between age and both post-operative reduction (p = 0.010) and arthritis (p = 0.014). The presence of quadrilateral plate comminution and gull-sign were associated to poor post-operative reduction (p = 0.016) and low Harris Hip Score (p = 0.049) respectively. CONCLUSION Quadrilateral plate reconstruction with a buttress plate though the ilioinguinal approach remains a valid method of fixation in acetabular surgery. Additional studies are needed to compare the efficiency of this method to new surgical approaches and fixation implants.

Abstract
Long antegrade cephalomedullary nailing is the standard of surgical care of atypical subtrochanteric fractures of the femur. Long nailing of such fractures is a technically demanding procedure. Our case report discusses the management of sequential bilateral atypical subtrochanteric fractures in an elderly female patient and the technical issues pertaining to nailing of such fractures. During the nailing procedure of the second fracture, an intraoperative distal peri-implant fracture occurred and it was addressed with the application of a distal femoral locking plate. At 2 years postoperative follow-up, the patient was ambulating independently and had sufficient range of motion in both hips and knees.

Abstract
BACKGROUND This study aims to determine the incidence of pulmonary embolism (PE) in trauma and orthopedic patients within a regional tertiary referral center and its association with the pattern of injury, type of treatment, co-morbidities, thromboprophylaxis and mortality. METHODS All patients admitted to our institution between January 2010 and December 2011, for acute trauma or elective orthopedic procedures, were eligible to participate in this study. Our cohort was formed by identifying all patients with clinical features of PE who underwent Computed Tomography-Pulmonary Angiogram (CT-PA) to confirm or exclude the clinical suspicion of PE, within six months after the injury or the surgical procedure.Case notes and electronic databases were reviewed retrospectively to identify each patient's venous thromboembolism (VTE) risk factors, type of treatment, thromboprophylaxis and mortality. RESULTS Out of 18,151 patients admitted during the study period only 85 (0.47%) patients developed PE (positive CT-PA) (24 underwent elective surgery and 61 sustained acute trauma). Of these, only 76% of the patients received thromboprophylaxis. Hypertension, obesity and cardiovascular disease were the most commonly identifiable risk factors. In 39% of the cases, PE was diagnosed during the in-hospital stay. The median time of PE diagnosis, from the date of injury or the surgical intervention was 23 days (range 1 to 312). The overall mortality rate was 0.07% (13/18,151), but for those who developed PE it was 15.29% (13/85). Concomitant deep venous thrombosis (DVT) was identified in 33.3% of patients. The presence of two or more co-morbidities was significantly associated with the incidence of mortality (unadjusted odds ratio (OR) = 3.52, 95% confidence interval (CI) (1.34, 18.99), P = 0.034). Although there was also a similar clinical effect size for polytrauma injury on mortality (unadjusted OR = 1.90 (0.38, 9.54), P = 0.218), evidence was not statistically significant for this factor. CONCLUSIONS The incidence of VTE was comparable to previously reported rates, whereas the mortality rate was lower. Our local protocols that comply with the National Institute for Health and Clinical Excellence (NICE) guidelines in the UK appear to be effective in preventing VTE and reducing mortality in trauma and orthopedic patients.

Abstract
BACKGROUND Pelvic fractures (PFX) reflect high-energy trauma with high mortality and morbidity. AIM We attempted to determine: whether there is a decrease in levels of sporting and physical activity in patients with operatively-treated PFX; risk factors for decreased sporting activity; any correlation between sporting activity and quality of life in this group. METHODS Retrospective demographics on mechanism of injury, fracture type, associated injury and injury severity score, as well as prospective documentation of the level and frequency of sporting activity, were collected from adult patients treated operatively for a PFX between 2007 and 2010, using a specifically designed questionnaire. Quality of life before and after injury was also recorded using the EuroQol-5D health-outcome tool. RESULTS 80 patients without pre-existing musculoskeletal disability were enrolled. The mean age was 44.9 years (18-65). The mean follow-up was 30.5 months (12-39). A decrease in level and frequency of sporting activity was observed. It was associated with lower-extremity associated injuries, but not with injury severity score, PFX severity, PFX type, age, or timing of follow-up. Sporting activity before injury predicted higher levels of sporting participation after injury. Decreased sporting activity after injury was associated with decreased EuroQol-SD score. CONCLUSIONS Patients should be counselled on the likelihood of a reduction in sporting activities after surgically treated PFX. A larger multi-centre study is needed to further expand on the evidence of the true impact of PFX and its associated injuries on sporting activity.

Abstract
The current available evidence for the use of bone graft substitutes in the management of subchondral bone defects associated with tibial plateau fractures as to their efficiency and safety has been collected following a literature review of the Ovid MEDLINE (1948-Present) and EMBASE (1980-Present). Nineteen studies were analysed reporting on 672 patients (674 fractures), with a mean age of 50.35 years (range 15-89), and a gender ratio of 3/2 males/females. The graft substitutes evaluated in the included studies were calcium phosphate cement, hydroxyapatite granules, calcium sulphate, bioactive glass, tricalcium phosphate, demineralised bone matrix, allografts, and xenograft. Fracture healing was uneventful in over 90% of the cases over a variant period of time. Besides two studies reporting on injectable calcium phosphate cement excellent incorporation was reported within 6 to 36 months post-surgery. No correlation was made by any of the authors between poor incorporation/resorption and adverse functional or radiological outcome. Secondary collapse of the knee joint surface ≥ 2 mm was reported in 8.6% in the biological substitutes (allograft, DBM, and xenograft), 5.4% in the hydroxyapatite, 3.7% in the calcium phosphate cement, and 11.1% in the calcium sulphate cases. The recorded incidence of primary surgical site and donor site infection (3.6%) was not statistically significant different, however donor site-related pain was reported up to 12 months following autologous iliac bone graft (AIBG) harvest. Shorter total operative time, greater tolerance of early weight bearing, improved early functional outcomes within the first year post-surgery was also recorded in the studies reporting on the use of injectable calcium phosphate cement (Norian SRS). Despite a lack of good quality randomised control trials, there is arguably sufficient evidence supporting the use of bone graft substitutes at the clinical setting of depressed plateau fractures.

A structured autopsy-based audit of 370 firearm fatalities: Contribution to inform policy decisions and the probability of the injured arriving alive at a hospital and receiving definitive care. ACCIDENT; ANALYSIS AND PREVENTION 2013; 50:667-677. [PMID: 22809705 DOI: 10.1016/j.aap.2012.06.018] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/14/2010] [Revised: 06/16/2012] [Accepted: 06/18/2012] [Indexed: 06/01/2023]
Abstract
UNLABELLED The objectives of this autopsy-based audit of firearm-related fatalities were to acquire data to inform policy decisions and to assess the probability of the injured arriving alive at a hospital and receiving definitive care. EVALUATED VARIABLES Demographics; co-morbidities; location and intention of the injury; toxicology; types of firearms; Abbreviated Injury Scale; Injury Severity Score (ISS); transfer means and time; and location of death. RESULTS Of a total of 370 fatalities, 85.7% were male. The median age was 38 (9-95) years. Suicides (47%) and assaults (45.1%) were the most common underlying intentions. The most seriously injured regions were the head (44.5%), thorax (25.7%), abdomen (10.7%), and spine (5.7%). Of the 370 total subjects, 4.9% had an ISS<16 and 59.5% had an ISS≤74; both groups were classified as potentially preventable deaths. The majority (84%) died at the scene, and only 9.8% left the emergency department alive for further treatment. Multivariate analyses documented that postmortem ISS is an independent factor that predicts the probability of the injured reaching a hospital alive and receiving definitive care. Individuals injured in greater Athens and those most seriously injured in the face, abdomen or spine had significantly greater chances of reaching a hospital alive and receiving definitive care, whereas those injured by a shotgun and the positive toxicology group were significantly less likely to. In conclusion, this study provides data to inform policy decisions, calls for a surveillance network and establishes a baseline for estimating the probability regarding the location of firearm-related deaths.

Abstract
BACKGROUND Subtrochanteric femoral non-unions in the setting of failed metalwork pose a challenging clinical problem. This study assessed the clinical outcome of patients treated according to the principles of the "Diamond" concept. METHODS Between 2007 and 2011 all patients presented with a subtrochanteric atrophic aseptic non-union in the setting of metalwork failure (broken cephalomedullary reconstruction nail), and treated in a single tertiary referral unit were included to this study. The hypertrophic and the non-unions of pathologic fractures were excluded. The revision strategy was based on the "Diamond concept"; optimisation of the mechanical and the biological environment (implantation of growth factor (rhBMP-7), scaffold (RIA bone graft from contralateral femur) and concentrated mesenchymal stem cells (MSCs) harvested from the iliac crest). The minimum follow up was 26 months (16-48). RESULTS Fourteen patients met the inclusion criteria. A specific sequence of metalwork failure was noted with initial breakage of the distal locking screws followed by nail breakage at the lag screw level. The intraoperative examination of the removed nails revealed no gross structural damage indicative of inappropriate drilling at the time of the initial intramedullary nailing. Varus mal-alignment was present in the majority of the cases, with an average of 5.2 degrees (0-11). The average time to distal locking screw failure was 4.4 months (2-8.5) and nail failure was 6.5 months (4-10). The time to union after the revision surgery was 6.8 months (5-12). Complications included two deaths in elderly patients (due to unrelated causes), one pulmonary embolism, one myocardial infarction, one below the knee deep vein thrombosis and one blade plate failure that required further revision with double plating and grafting. CONCLUSION Varus mal-alignment must be avoided in the initial stabilisation of subtrochanteric fractures. Distal locking screw failure is predictive of future fracture non-union and nail breakage. In the absence of sepsis, a single stage procedure based on the "Diamond concept" that simultaneously optimizes the mechanical and biological environment is a successful method for managing complex subtrochanteric atrophic non-unions with failed metalwork.

Alcohol and psychoactive drugs increased the pre-hospital mortality in 655 fall-related fatalities in Greece: a call for management protocols. Injury 2012; 43:1522-6. [PMID: 21194690 DOI: 10.1016/j.injury.2010.11.056] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2010] [Revised: 11/11/2010] [Accepted: 11/22/2010] [Indexed: 02/02/2023]
Abstract
INTRODUCTION The frequency of alcohol and psychoactive drugs in fall-related fatalities and their effect on type, severity of injury and location of death constitute the subjects of this study. METHODS A retrospective analysis based on autopsy and toxicology compared demographics, location of injury; intention for the injury, height of fall, Abbreviated Injury Scale--90 (AIS-90), post-mortem Injury Severity Score (ISS), and location of death. RESULTS Amongst 655 fall-related fatalities screened for alcohol and psychoactive drugs 123 (18.8%) were classified in the positive toxicology group (PTG) and the remaining in the negative toxicology group (NTG). The median ages were 48 (16-94) years for the PTG and 62 (12-96) years for the NTG. The screened represent 31% of the national toll. The median height of fall was 7 m and the median blood alcohol concentration was 53 (1.5-630)mg/dl. Males were more likely to be included in the PTG than females (21.6 versus 13.6%; p = 0.014) as were the aged between 11 and 60 years. The odds of severe (AIS ≥ 3) head, thoracic, abdominal, extremity, and spine injuries were not influenced by toxicology status. Fatalities of the PTG were as likely to have severe trauma (ISS ≥ 16) as were fatalities of the NTG (93.5 versus 90.8%; p = 0.34). There was no significant difference of ISS between PTG (median ISS 43, range: 6-75) and NTG (median ISS 35, range: 3-75). Nevertheless, 76.4% of the subjects of the PTG died during the pre-hospital stage of care compared to 60.5% of the subjects of the NTG, which was highly significant (or = 2.80, p = 0.001) after controlling for confounders as age, gender, intention for injury, height of fall, and ISS. CONCLUSIONS In fall related trauma, alcohol and psychoactive drugs increased the risk of death during the pre-hospital stage by 2.80 times. This is strong evidence that specific protocols for their early management should be instituted.

Reconstruction of iliac crest with bovine cancellous allograft after bone graft harvest for symphysis pubis arthrodesis. INTERNATIONAL ORTHOPAEDICS 2012; 36:1701-7. [PMID: 22729663 DOI: 10.1007/s00264-012-1572-z] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/10/2012] [Accepted: 05/01/2012] [Indexed: 11/24/2022]
Abstract
PURPOSE The aim of this study was to evaluate the safety and efficiency, as well as the incorporation characteristics of a specific type of xenograft used for iliac crest defects post-harvesting tri-cortical iliac crest bone graft. METHODS Sixteen patients diagnosed with chronic anterior pelvic pain were operated for pubic symphysis fusion. The tri-cortical graft harvested from the iliac crest was inserted into the pubic symphysis and compressed with a reconstruction plate. The defect in the iliac crest was filled with a block of cancellous bovine substitute (Tutobone®). The length of iliac crest defect, time to fusion of pubic symphysis, time to incorporation of the graft and complications were recorded. The postoperative pain and patients' satisfaction were evaluated. RESULTS The median age of patients was 36.5 years (range 27-75). Fusion was obtained in 15 patients (94 %). The median time to fusion was four months (range three to seven). The length of the iliac crest bone defect ranged from 40 to 70 mm. Integration of the bovine substitute was achieved in 15 patients (94 %) over a median period of three months (range two to six). The postoperative median pain score was 2 (range 1-5). Twelve patients (75 %) reported good satisfaction. No major complications or allergic reactions were observed. CONCLUSIONS The xenograft used in this study provided a safe and effective method of reconstruction of iliac crest donor site defects. It has satisfactory incorporation, high biocompatibility and no signs of inflammatory reactions. This new technique is simple and easily reproducible in routine clinical practice.

Abstract
This article describes a novel, clinically oriented classification system for long-bone fractures that is simple, reliable, and useful to predict treatment method, complications, and outcome. The reliability and memorability of the new classification were statistically tested and compared with the AO-Müller/Orthopaedic Trauma Association (AO/OTA) long-bone fracture classification. The proposed classification system was also clinically validated with a targeted pilot study designed for content and clinical outcome retrospectively reviewing 122 closed tibial shaft fractures, which were used as a representative paradigm of long-bone fractures. Statistical evaluation showed that the proposed classification system had improved inter- and intraobserver variation agreement and easier memorability compared with the AO/OTA classification system. The clinical validation study showed its predictive value regarding selection of treatment method, complication rate, and injury outcome.The proposed classification system proved simple, reliable, and memorable. Its clinical value appeared strong enough to justify the organization of larger studies for a complete assessment of its clinical usefulness for all long-bone fractures.

What is the effect of compartment syndrome and fasciotomies on fracture healing in tibial fractures? Injury 2011; 42:1402-7. [PMID: 21993369 DOI: 10.1016/j.injury.2011.09.007] [Citation(s) in RCA: 48] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 09/15/2011] [Indexed: 02/02/2023]
Abstract
Acute compartment syndrome (ACS) in tibial diaphyseal fractures has been associated with such complications as infection, delayed fracture healing or non-union, sensory and motor deficits, deformities, and poor functional outcome. Essential condition of an uncomplicated recovery is early diagnosis with prompt decompression. A comprehensive review of the literature was performed to evaluate the impact of compartment syndrome and leg fasciotomies on the time to fracture union and the incidence of delayed union and non-union in tibial diaphyseal fractures. A total of 16 articles, which included 245 tibial fractures complicated with compartment syndrome were analysed. There were statistically significant differences in the time to healing, being longer by 4.90 weeks (p<0.001), and in the rates of delayed union or non-union (55% versus 17.8%) (p<0.001) when these fractures were compared to tibial fractures without compartment syndrome. Patients with ACS of the tibia undergoing leg fasciotomies should be informed about the increased risk of impaired fracture healing and longer time to union.

Prevalence of complications of open tibial shaft fractures stratified as per the Gustilo-Anderson classification. Injury 2011; 42:1408-15. [PMID: 22019355 DOI: 10.1016/j.injury.2011.10.015] [Citation(s) in RCA: 168] [Impact Index Per Article: 12.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2011] [Revised: 10/12/2011] [Accepted: 10/12/2011] [Indexed: 02/02/2023]
Abstract
The aim of the present study was to comparatively analyse certain outcome measures of open tibial fractures, stratified per grade of open injury and method of treatment. For this purpose, a systematic review of the English literature from 1990 until 2010 was undertaken, comprising 32 eligible articles reporting on 3060 open tibial fractures. Outcome measures included rates of union progress (early union, delayed union, late union and non-union rates) and certain complication rates (deep infection, compartment syndrome and amputation rates). Statistical heterogeneity across component studies was detected with the use of Cochran chi-square and I(2) tests. In the absence of significant statistical heterogeneity a pooled estimate of effect size for each outcome/complication of interest was produced. All component studies were assigned on average a moderate quality score. Reamed tibial nails (RTNs) were associated with significantly higher odds of early union compared with unreamed tibial nails (UTNs) in IIIB open fractures (odds ratio: 12, 95% CI: 2.4-61). Comparing RTN and UTN modes of treatment, no significant differences were documented per grade of open fractures with respect to both delayed and late union rates. Surprisingly, nonunion rates in IIIB open fractures treated with either RTNs or UTNs were lower than IIIA or II open fractures, although the differences were not statistically significant. Significantly increased deep infection rates of IIIB open fractures compared with all other grades were documented for both modes of treatment (RTN, UTN). However, lower deep infection rates for IIIA open fractures treated with RTNs were recorded compared with grades I and II. Interestingly, grade II open tibial fractures, treated with UTN, presented significantly greater odds for developing compartment syndrome than when treated with RTNs. Our cumulative analysis, providing for each grade of open injury and each particular method of treatment a summarised estimate of effect size for the most important outcome measures of open tibial fractures, constitutes a useful tool of the practicing surgeon for optimal decision making when operative treatment of such fractures is contemplated.

Abstract
Bone infection in adults is a potentially devastating complication following trauma or surgery. The clinician should diagnose osteomyelitis based on certain clinical manifestations and on laboratory and imaging findings. For pathogen identification, the treating surgeon should take appropriate tissue samples. Close collaboration with microbiologists is of paramount importance to dictate the appropriate duration and type of antibiotics to be administered. Treatment of acute osteomyelitis requires surgical debridement and prolonged course of antibiotics. Debate exists regarding the maintenance or the removal of any internal fixation device. Treatment of chronic osteomyelitis is more complicated. For its eradication the treatment course is often prolonged and frustrating. Based on the current literature an algorithm of treatment for both acute and chronic bone infections is recommended.

Abstract
In England, trauma is the leading cause of death across all age groups, with over 16,000 deaths per year. Major trauma implies the presence of multiple, serious injuries that could result in death or serious disability. Successive reports have documented the fact that the current ad hoc unstructured management of this patient group is associated with considerable avoidable death and disability. The reform of trauma care in England, especially of the severely injured patient, has already begun. Strong clinical leadership is embraced as the way forward. The present article summarises the steps that have been made over the last decade that led to the recent decision to move towards a long anticipated restructure of the National Health Service (NHS) trauma services with the introduction of Regional Trauma Networks (RTNs). While, for the first time, a genuine political will and support exists, the changes required to maintain the momentum for the implementation of the RTNs needs to be marshalled against arguments, myths and perceptions from the past. Such an approach may reverse the disinterest attitude of many, and will gradually evolve into a cultural shift of the public, clinicians and policymakers in the fullness of time.

Abstract
Bone grafting is a commonly performed surgical procedure to augment bone regeneration in a variety of cases in orthopaedic and maxillofacial surgery. Autologous bone graft remains to be the 'gold standard' and the iliac crest to be the most common harvesting site. The intramedullary canal of long bones represents another potential site for large volume of autologous bone graft harvesting and is recently being used as an alternative donor site. However, harvesting of autologous bone graft is associated with morbidity and a number of complications. The aim of this systematic review was to collect and summarise the existing data on reported complications after harvesting autologous bone from the iliac crest (anterior and posterior) and the long bone intramedullary canal using the RIA device. We searched the PubMed Medline and Ovid Medline databases, from January 1990 to October 2010, to retrieve all relevant articles. A total of 92 articles (6682 patients) were included in the analysis. Overall, the complication rate following RIA was 6% (14 complications in 233 patients) and 19.37% after iliac crest bone graft harvesting (1249 complications in 6449 patients). The rate of each of the reported complications was assessed and, when the donor site was properly documented, comparison within the anterior and posterior iliac crest donor sites was performed. Although the difference of the overall morbidity rates between the two harvesting sites was not statistically significant (p=0.71); the rates of certain complications were found to significantly differ when anterior or posterior iliac crest was used. The rates of infection (p=0.016), haematoma formation (p=0.002), fracture (p=0.017), and hyperthrophic scar (p=0.017) were significantly higher when the donor site was the anterior iliac crest compared to the posterior iliac crest; whereas the rates of chronic donor site pain (p=0.004) and sensory disturbances (p=0.003) were significantly lower. The incidence of bone graft harvesting related complications can be reduced further if certain principles are followed depending on the performed harvesting methods; but overall the use of RIA device as harvesting method seems a promising alternative with a low complication rate.
