Management of complex fractures poses a significant challenge. Evolving research and changes to national guidelines suggest better outcomes are achieved by transfer to specialist centres. The development of Major Trauma Networks was accompanied by relevant financial arrangements. These do not apply to patients with closed fractures referred for specialist treatment by similar pathways. Despite a surge in cases transferred for care, there is little information available regarding the financial impact on receiving institutions. This retrospective study examines data from a Level 1 trauma centre. Patients were identified from our electronic referral system, used for all referrals. Transferred adult patients, undergoing definitive treatment of acute isolated closed tibial fractures, were included for a 2-year period. Data was collected using our clinical and Patient Level Information and Costing (PLICS) systems including coding, demographics, treatment, length of stay (LOS), total operative time, number of operations, direct healthcare costs, and NHS reimbursements.Introduction

The aim of this study was to assess the impact of Covid-19 measures on the rate of surgical site infections (SSI) and subsequent readmissions in orthopaedic patients. Retrospective, observational study in a level 1 major trauma center comparing rates of SSI in orthopaedic patients who underwent surgery prior to the Covid-19 lockdown versus that of patients who underwent surgery during the lockdown period. A total of 1151 patients were identified using electronic clinical records over two different time periods; 3 months pre Covid-19 lockdown (n=680) and 3 months during the Covid-19 lockdown (n=470). Patients were followed up for 1 year following their initial procedure. Primary outcome was readmission for SSI. Secondary outcomes were treatment received and requirement for further surgeries. The most commonly performed procedures were arthroplasty and manipulation under anaesthesia with 119 in lockdown vs 101 non-lockdown (p=0.001). The readmission rate was higher in the lockdown group with 61 (13%) vs 44 (6.5%) in the non-lockdown group (p <0.001). However, the majority were due to other surgical complications such as dislocations. Interestingly, the SSI rates were very similar with 24 (5%) in lockdown vs 28 (4%) in non-lockdown (p=0.472). Twenty patients (4.2%) required a secondary procedure for their SSI in the lockdown group vs 24 (3.5%) in non-lockdown (p=0.381). Mortality rate was similar at 44 (9.3%) in lockdown vs 61 (9.0%; p=0.836). Whilst Covid-19 precautions were associated with higher readmission rates, there was no significant difference in rate of SSI between the two groups.
The management of upper limb nonunions can be challenging and often with unpredictable outcomes. In the study we present the results of treatment of upper limb nonunions treated in our institution with BMP-7 biological enhancement. Between 2004 and 2011 all consecutive patients who met the inclusion criteria were followed up prospectively. Union was assessed with regular radiological assessment. At the final follow up clinical assessment included the disabilities of the Arm, Shoulder and Hand (DASH) score, range of movement and patient satisfaction. The mean follow up was 12 months (12–36). In total 42 patients met the inclusion criteria with a mean age of 47. Anatomical distribution of the nonunion sites included 19 cases of mid/proximal radius/ulna, 14 humerus, 6 distal radius and 3 clavicles. 5 patients had septic nonunion, 35 had atrophic nonunion, 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 application was 1.5 and 26 months, respectively. 40 patients had both clinical and radiological union whereas 2 had partial radiological union but a pain free range of motion. BMP was applied in isolation in 1 case and 41 cases the application was combined with autologous bone grafting. The range of movement of the affected limb, DASH score and patient satisfaction were optimum at the final follow up. This study supports the use of BMP-7 as a bone stimulating adjunct for the treatment of complex and challenging upper limb nonunions.
Clavicle fractures can cause pain and functional impairment if not managed appropriately. This paper evaluates the prevalence of clavicular fractures, estimates number of cases requiring operative treatment, whether removal of implant is a frequent necessity and compares the final functional outcome of the operative and non-operative group. Between November 2005 and November 2007 patients with clavicular fractures were eligible for participation. Patients below 18 years of age, and pathological fractures were excluded. Operative versus non-operative treatment, radiographic classification (Allman system), complications, implant removal, and functional outcome using the University of California Los Angeles (UCLA) shoulder scores were documented and analysed.Introduction
Materials/Methods
Pelvic fractures are indicators of severe trauma and high energy absorption. They are associated with multiple local or distant concomitant injuries, which explain their high mortality and morbidity. The aim of this study is to investigate the late sequel of traumatic-pelvic-fractures (PFX) focusing on quality-of-life and sexual-function. From a database of prospectively documented data, patients who had suffered a PFX and had been treated operatively in our institution from January 2008–2009 were recruited. Exclusion criteria were patients less than one-year post-injury, pathological-fractures, patients < 18 or >65, and patients with co-morbidities linked to sexual dysfunction. Demographics, injury-mechanisms, fracture-patterns (Young-Burgess classification), injury-severity-score (AIS/05-ISS), urogenital injuries and clinical outcome were recorded and analysed. Health-related-quality-of-life was assessed using the (EuroQol-5D) and sexual-function using the international-index-of-erectile-function and the female-sexual-function-index. The minimum follow-up was 12 months (12–30).Introduction
Methods
Reaming of the canal is an important step in the debridement phase of treating intramedullary infections. Numerous techniques of radical canal debridement have been successfully reported. The use of the Reamer-Irrigation-Aspiration system (RIA-Synthes) is currently expanding to include this clinical scenario. Prospective collection of data related to infected cases treated with the use of the RIA in a tertiary referral centre referring to a 3 year period. Peri-operative details, microbiology results, and follow-up outcome over a minimum period of 12 months post-surgery are reported.Introduction
Materials and methods
The management of non-unions of subtrochanteric femoral fractures with associated implant failure is challenging. This study assessed the outcome of a cohort of patients treated according to the diamond concept. Between 2005–2010 all patients with subtrochanteric aseptic non-unions presented post implant failure (Gamma Nail breakage) were eligible in the absence of severe systemic pathologies and comorbidities. Demographics, initial fracture pattern, method of stabilisation, mode of failure of metal work, time to revision of fixation, complications, time to union, and functional outcome were recorded over a minimum period of follow-up of 12 months. The revision strategy was based on the “diamond concept;” optimising the mechanical and biological environment (revision of fixation, osteoinduction/BMP-7, osteoconduction/RIA harvested graft, and osteogenicity/concentrate of bone marrow aspirate).Background
Methods
To evaluate management, direct-medical-costs and clinical outcome profile of a large trauma unit with respect to simple elbow dislocations. All simple elbow dislocations that were defined as not requiring acute surgical intervention, post-reduction, were considered between Jan-2008 and Dec-2010. Inclusion criteria consisted of age greater than 13; absence of major associated fractures, successful closed reduction, and follow-up as an outpatient. The management of these patients was classified in terms of immobilisation time into: short (< 2weeks), standard (2–3weeks) and prolonged (>3weeks). Direct-medical-costs were calculated based on current tariff rates associated with radiology, admission, theatre time (for reductions and recovery) and outpatient attendances. Clinical outcome was evaluated with respect to complications, secondary procedures, and time before discharge from clinic.Objectives
Methods
The aim of this study was to evaluate the health quality of life and return to sports activities following pelvic ring injuries. Between January 2006–2007 patients treated in our institution with pelvic fractures were eligible to participate. Inclusion criteria were adult patients. Exclusion criteria were children and pathological fractures. Data recorded included demographics, injury mechanism, fracture pattern, Injury severity score (ISS), associated injuries, method of fixation, complications and functional outcome. Health related quality of life was assessed using the (EuroQol) and return to sports activities was evaluated using a return to sports questionnaire. The minimum follow up was 24 months (24–39)Introduction
Patients and Methods
The clinical and functional outcome following simultaneous fractures of the acetabulum and pelvic ring represent a challenge for the clinician and are currently obscure in the existing literature. Between January 2003 and July 2009 all patients with combined pelvic and acetabular fractures were included in this prospectively study. Demographic details, mechanism of injury, ISS, surgical procedures, post-operative course, length of hospital stay, and radiological (Matta's score) and functional outcomes (The Merle d' Aubigne hip score) were recorded. The minimum follow up was 12 months (12–72).Introduction
Patients and Methods
The aim of this study was to investigate the differences between open vs closed femoral fractures with regard to the epidemiology, classification and outcome. Data collected prospectively from MTOS and TARN-UK. Between 2001 and 2005, 67,665 trauma patients found and 8,591 were identified having sustained femoral shaft fractures. Demographics, pre and in-hospital data were recorded. The AIS and ISS were calculated. Outcomes and mortality rates were recorded. Four groups of patients were identified namely isolated/open (IO), polytrauma/open (PO), isolated /closed (IC), polytrauma/closed (PC). ANOVA analysis was contacted to determine the effect of fracture classification and severity of trauma to mortality using SPSS 11.0 software.Introduction
Patients & methods
Grade IIIa/b open tibial fractures (OTF) result mostly following high energy trauma and may be accompanied by significant associated injuries. Aim of this study was to compare the characteristics and the outcome of OTF between patients of different injury severities. Retrospective analysis of the records of patients admitted to a level I centre in a 4 year period with an OTF. Epidemiologic data, AO-ASIF classification, method of treatment, complication rates and time to fracture-union have been statistically analysed. An AIS98-ISS threshold (ISS 16) was used to separate OTF in 2 groups (A<16, B>16).Introduction
Materials and methods
Femoral fracture non-unions are considered to be rare, and are usually treated successfully with exchange nailing. However, recalcitrant aseptic cases often require additional bone grafting. The efficacy of BMP-7 in the treatment of recalcitrant aseptic femoral non-unions was studied. Since 2003 a multicenter registry (bmpusergroup.co.uk) was created collecting details of BMP7 application in general, between different university hospitals across Europe. Demographic data, intraoperative details, complications, clinical outcome parameters, radiological healing, VAS pain score, EuroQol-5D, and return-to-work were prospectively recorded. Radiological healing was defined as the presence of callous in two planes over 3 cortices. The minimum follow up was 12 months. Seventeen patients, who had undergone a median of 1(1 to 4) prior revision operations, over a median period from the injury of 17 months(9 to 42), were included in this observational study. In 76.4%(13/17) the BMP7 was combined with revision of the fixation. Non-union healing was verified in 14/17 cases(82.3%) in a median period of 6.5 months(3–15). Over 80% of these patients returned to their pre-injury level of activities, the median overall health state score was 82.5(35 to 100). No adverse events or complications were associated with the BMP7 application over the median follow-up of 24 months(12–68).
The purpose of this study was to investigate the outcome of acetabular fractures treated in our institution with marginal impaction. Over a 5 year period consecutive acetabular cases treated in our institution with marginal impaction were eligible for inclusion in this study. Exclusion criteria were patients lost to follow up and pathological fractures. A retrospective analysis of prospectively documented data was performed. Demographics, fracture types according to the Judet-Letournel classification, radiological criteria of intra-operative reduction (Matta) and secondary collapse, complication rates, and the EuroQol-5D questionnaire were documented over a median period of follow-up of 40 months (12–206). Out of 400 cases, eighty-eight acetabular fractures met the inclusion criteria. The majority (93.2%) involved males with a median age of 40.5 years (16–80). Half of them were posterior-wall fractures, 21.6% bicolumn, 14.7 %posterior-wall and column, 6.8% transverse, 5.7% anterior-column, 1.1% anterior-column posterior hemi-transverse. In 75% of the cases anatomical intra-operative reduction was achieved. Structural-bone-graft was used in 73.9%, and two-level reconstruction in 61%. At the last follow-up, the originally achieved anatomical reduction was lost in 17/66 (25.8%), (10 PW, 4 PC+PW, 1 PC, 1 Transverse, 1 Bicolumn fracture). Avascular necrosis developed in 9.1% and heterotopic ossification in 19.3%. Full return to previous activities was documented in 48.9% of cases, the EuroQol general heath state score had a median of 80% (30–95%), full recovery was recorded as to the patients’ mobility in 51.1%, as to pain in 47.7%, as to self-care in 70.5%, as to work-related activities in 55.7%, and as to emotional parameters in 65.9%. Reoperation (heterotopic-ossification excision, total-hip-arthroplasty, removal of metalwork) was necessary in 19.2% of cases. Utilising different techniques of elevation of the articular joint impaction leads to joint preservation with satisfactory overall functional results. Secondary collapse was noted in 25.8% of the patients predisposing to a poorer outcome
Anterior wall and/or column acetabular fractures (AW/ C) have a low incidence rate. Paucity of information exists regarding the clinical results of these fractures. We present our experience in treating AW/C at a tertiary referral centre. Between Jan-2002 and Dec-2007, 200 consecutive patients were treated in our institution with displaced acetabular fractures. All AW/C fractures according to the Letournel classification were included in the study. All patients underwent plain radiography and CT investigations. Retrospective analysis of the medical notes and radiographs was performed for type of associated injuries, operative technique, peri-operative complications. Radiological assessment of fracture healing was determined by Matta’s criteria and functional hip scores were assessed using Merle-d’-Aubigne scoring. The mean follow up was 44.5 months (28–64). 15 patients (10 males) met the inclusion criteria (mean age 55.5 years). Four had associated anterior dislocation. Associated injuries included pneumothorax, splenic rupture, tibial and distal radius fractures. Five were treated by percutaneous methods, 8 with plate-screw fixation, and 2 with circlage wire, (10 ilioinguinal approaches). Mean time-to-surgery was 14 days(10–21 days). The average operative time for the percutaneous group was 75min vs. 190min in the orif group. Mean postoperative-in-patient-stay was 4 days(3–7 days), and 21 days(14–37 days). One patient developed chest infection post-operatively, two loss of sensation over the distribution of lateral cutaneous nerve. None of them developed incisional hernia, deep venous thrombosis and pulmonary embolism. At the last follow-up radiological outcome was excellent in 11 and good in 4 patients; clinical outcome was excellent in 12 and good in 3 patients, and none of the patients has developed heterotopic calcification or early osteoarthritis. Our results on management of these fractures are comparable to the early results reported by Letournel. Operative treatment for the rare anterior wall and anterior column fractures yields a favourable outcome resulting in early mobilization with limited patient morbidity
To evaluate the effectiveness of Pulsed-Lavage and of Versajet-hydrosurgery in removing two Staphylococcus aureus strains from porcine tissue and graphite powder from simulated fractures. Overnight broth cultures (NCTC-6571) and S.aureus strains were diluted to yield inocula containing 1x103c. f.u. ml-1. Initially 8 porcine legs were used; porcine tissues were inoculated with 10ml of either of the two S.aureus strains. Control tissues were inoculated with PBS. All inoculated samples were irrigated with 300ml of saline using the pulsed-lavage system or using the Versajet. 10ml of each of the following were plated out in triplicate:
inoculum pre-incubation inoculum post-incubation, each left over inoculum following removal of tissue and dilutions of 10-1 and 10-2 and Wash from all samples. Eight additional porcine legs were used where 2 incisions were made down to bone in a cross-hatch pattern. 1g of graphite powder was infiltrated into each fracture site to simulate a contaminated open fracture. Each fracture site was irrigated with 500ml saline through pulsed-lavage or Versajet. The average microbiological reduction using Pulsed-Lavage or Versajet was 2% and 15% respectively. The clinical S.aureus strain was more adherent than the laboratory strain. The Versajet maintained a 12–16% reduction of S.aureus, whereas pulsed-lavage did not reduce contamination. The number of graphite particles was significantly reduced with the use of the Versajet system compared with the pulsed-lavage. Versajet system was more effective in removal of foreign particles and more effectively reduced the micro-biological load of both examined S.aureus strains in a porcine model. Further studies are indicated to evaluate the efficacy of this system in clinical practice
The role of the pro-inflammatory cytokine HMGB1 (alarmins) has not been investigated in the clinical setting. This study aims to assess its relationship to IL-6 release, ISS, and to quantify the second hit phenomenon after femoral nailing. 22 (13 males, mean age 37.5y) consecutive patients entered in this prospective randomised trial. All patients underwent stabilisation of the femoral shaft fracture with reamed (10 patients) or unreamed nailing. Patient demographics, ISS, and complications were recorded prospectively. Peripheral blood samples were collected on admission, induction of anaesthesia, entry into femoral canal, wound closure and on day 1, 3, and 6. Serum HMGB1 and IL-6 concentrations were measured using ELISAs. 6 healthy volunteers formed the control group. The median ISS was 14.5 (9–29). Admission median HMGB1 and IL-6 concentrations were 7.2 ng/ml and 169 pg/ml respectively. A direct correlation was observed between ISS and IL-6 and HMGB1 concentrations. HMGB1 concentrations reached to peak levels on day-6. On the contrary, the median concentration of IL-6 peaked around day 1 postoperatively (reamed: 780 vs. unreamed: 376 pg/ml) and then showed a downward trend. The median increase of HMGB1 by day 6 was 4.21ng/ml in the reamed and 2.98ng/ml in the unreamed population; the median increase of IL-6 by day 1 measured 462 pg/ml and 232 pg/ml in the respective groups. Day 6 concentration of HMGB1 in patients with an ICU stay >
5 days (n=4), compared to the rest of the patients (n=16), was 11.04ng/ml (6.13 – 35.84) vs. 7.14ng/ml (4.06 – 12.8), (p=0.03). Femoral nailing and reaming induces a second hit as supported by the post-operative increased levels of both IL-6 and HMGB1. While IL-6 has been suggested as a marker of assessment of the early inflammatory response, alarmins can provide useful information at the later stage of an evolving immuno-inflammatory process.
