Treatment of posterior malleolar (PM) ankle fractures remain controversial. Despite increasing recommendation for small PM fragment fixation, high quality evidence demonstrating improved clinical outcomes over the unfixated PM is limited. We describe the medium-to-long term clinical and radiographical outcomes in younger adult patients with PM ankle fractures managed without PM fragment fixation. A
Primary total joint arthroplasty (TJA) is an increasingly common and safe way of treating joint disease. Robust preoperative assessment improved intraoperative techniques and holistic rehabilitation contribute to an uneventful postoperative period. Despite there being evidence against the utility of postoperative blood tests, it is still often part of routine practice. We aim to evaluate the usefulness of these tests by investigating their incidence following TJA as well as identifying preoperative risk factors for abnormal blood test results postoperatively especially pertaining to anaemia and acute kidney injury (AKI). This is a
Elderly patients undergoing surgery for a hip fracture are at risk of thromboembolic events (TEV). The risk of TEV is now rare due to thromboprophylaxis. However, hip fracture treatment has evolved over the last decade. The risk of TEV may have been modified. The objective of this study was to determine the risk of symptomatic TEV following surgery for a hip fracture, in an elderly population.
The purpose of this study is to evaluate risk factors for distal construct failure (DCF) in posterior spinal instrumented fusion (PSIF) in adolescent idiopathic scoliosis (AIS). We observed an increased rate of DCF when the pedicle screw in the lowest instrumented vertebra (LIV) was not parallel to the superior endplate of the LIV, however this has not been well studied in the literature. We hypothesise a more inferiorly angled LIV screw predisposes to failure and aim to find the critical angle that predisposes to failure. A
Abstract. Background. The gold standard treatment for Anterior Cruciate Ligament injury is reconstruction (ACL-R). Graft failure is the concern and ensuring a durable initial graft with rapid integration is crucial. Graft augmentation with implantable devices (internal brace reinforcement) is a technique purported to reduce the risk of rupture and hasten recovery. We aim to compare the short-term outcome of ACL-R using augmented hamstring tendon autografts (internally braced with neoligament) and non-augmented hamstring autografts. Methods. This was a
Aim. Periprosthetic joint infections (PJI) are a rare, but devastating complication. Diagnostic approaches to PJI vary greatly between different centers. Most commonly tissue biopsies and synovial fluid sampling are recommended for identification pathogens causing PJI. However, sensitivity and specificity of those techniques have been shown to be highly dependent on preanalytical factors like time and conditions of transportation, location of sampling, as well as analytical approaches and prolonged incubation for up to 14days. Sonication of explanted orthopedic devices has been shown to be more than only an addition in the diagnosis of PJI. The goal of this study was to evaluate the diagnostic value of sonication in PJI. Method.
Introduction. Robotic-assisted total knee arthroplasty (TKA) was introduced to improve limb alignment, component positioning, and soft-tissue balance, yet the effect of adoption of this technology has not been established. This study was designed to evaluate whether robotic-assisted TKA leads to improved patient reported outcome measures (PROMs) and patient satisfaction as compared to conventional TKA at 3 and 12 months. Methods. This IRB-approved single-surgeon
Introduction. Ankle fractures in the elderly have been increasing with an ageing but active population and bring with them specific challenges. Medical co-morbidities, a poor soft tissue envelope and a requirement for early mobilisation to prevent morbidity and mortality, all create potential pitfalls to successful treatment. As a result, different techniques have been employed to try and improve outcomes. Total contact casting, both standard and enhanced open reduction internal fixation, external fixation and most recently tibiotalocalcaneal (TTC) nailing have all been proposed as suitable treatment modalities. Over the past five years popular literature has begun to herald TTC nailing as an appropriate and contemporary solution to the complex problem of high-risk ankle fragility fractures. We sought to assess whether, within our patient cohort, the outcomes seen supported the statement that TTC has equal outcomes to more traditional open reduction internal fixation (ORIF) when used to treat the high-risk ankle fragility fracture. Materials & Methods. Results of ORIF versus TTC nailing without joint preparation for treatment of fragility ankle fractures were evaluated via
Introduction. Non-union is agonising for patients, complex for surgeons and a costly burden to our healthcare service; as such, its management must be well defined. There is debate as to the requirements for the successful treatment of such patients, in particular, the need for additional biological therapies to ensure union. This study's primary aim was to determine if operative treatment alone was an effective treatment for the non-union of long bones in the upper and lower limbs compared to the pre-existing literature using biological therapies.

INTRODUCTION. To test whether there are differences in postoperative mechanical and component alignment, and in functional results, between conventional, navigated and patient-specific total knee arthroplasties in a low-volume centre?. MATERIAL AND METHODS.
Radial head fractures are relatively common, representing approximately one-third of all elbow fractures. Outcomes are generally inversely proportional to the amount of force involved in the mechanism of injury, with simple fractures doing better than more comminuted ones. However, the prognosis for these fractures may also be influenced by associated injuries and patient-related factors (age, body index mass, gender, tobacco habit, etc.) The purpose of this study is to evaluate which factors will affect range of motion and function in partial radial head fractures. The hypothesis is that conservative treatment yields better outcomes. This
Demand for total knee arthroplasty (TKA) is increasing as it remains the gold-standard treatment for end-stage osteoarthritis (OA) of the knee. While magnetic-resonance imaging (MRI) scans of the knee are not indicated for diagnosing knee OA, they are commonly ordered prior to the referral to an orthopaedic surgeon. The purpose of this study was to determine the proportion of patients who underwent an MRI in the two years prior to their primary TKA for OA. Secondary outcomes included determining patient and physician associations with increased MRI usage. This is a population-based cohort study using billing codes in Ontario, Canada. All patients over 40 years-old who underwent a primary TKA between April 1, 2008 and March 31, 2017 were included. Statistical analyses were performed using SAS and included the Cochran-Armitage test for trend of MRI prior to surgery, and predictive multivariable regression model. Significance was set to p<0.05. There were 172,689 eligible first-time TKA recipients, of which 34,140 (19.8%) received an MRI in the two years prior to their surgery. The majority of these (70.8%) were ordered by primary care physicians, followed by orthopaedic surgeons (22.5%). Patients who received an MRI were younger and had fewer comorbidities than patients who did not (p<0.001). MRI use prior to TKA increased from 15.9% in 2008 to 20.1% in 2017 (p<0.0001). Despite MRIs rarely being indicated for the work-up of knee OA, nearly one in five patients have an MRI in the two years prior to their TKA. Reducing the use of this prior to TKA may help reduce wait-times for surgery.

Reduction of length of stay (LOS) without compromising quality of care is a trend observed in orthopaedic departments. To achieve this goal the pathway needs to be optimised. This requires team work than can be supported by e-health solutions. The objective of this study was to assess the impact of reduction in LOS on complications and readmissions in one hospital where accelerated discharge was introduced due to the pandemic. 317 patients with primary total hip and total knee replacements treated in the same hospital between October 2018 and February 2021 were included. The patients were divided in two groups: the pre-pandemic group and the pandemic group. The discharge criteria were: patient feels comfortable with going back home, patient has enough support at home, no wound leakage, and independence in activities of daily living. No face-to-face surgeon or nurse follow-up was planned. Patients’ progress was monitored via the mobile application. The patients received information, education materials, postoperative exercises and a coaching via secure chat. The length of stay (LOS) and complications were assessed through questions in the app and patients filled in standard PROMs preoperatively, at 6 weeks and 3 months. Before the pandemic, 64.8% of the patients spent 3 nights at hospital, whereas during the pandemic, 52.0% spent only 1 night. The median value changed from 3 days to 1 day. The complication rate before the pandemic of 15% dropped to 9 % during the pandemic. The readmission rate remained stable with 4% before the pandemic and 5 % during the pandemic. No difference were observed for PROMS between groups. The results of this study showed that after a hip and knee surgery, the shortening of the LOS from three to one night resulted in less complications and a stable rate of readmissions. These results are in line with literature data on enhanced recovery after hip and knee arthroplasty. The reduction of LOS for elective knee and hip arthroplasty during the pandemic period proved safe. The concept used in this study is transferable to other hospitals, and may have economic implications through reduced hospital costs.
Background. Coronal malalignment has been proposed as a risk factor for mechanical failure after total knee arthroplasty (TKA). In response to these concerns, technologies that provide intraoperative feedback to the surgeon about component positioning have been developed with the goal of reducing rates of coronal plane malalignment and improving TKA longevity. Imageless hand-held portable accelerometer technology has been developed to address some the limitations associated with other computer assisted navigation devices including line-of-sight problems, preoperative imaging requirements, extra pin sites, up-font capital expenditures, and learning curve. The purpose of this study was to compare the accuracy and precision of a hand-held portable navigation system versus conventional instrumentation for tibial and femoral resections in TKA. Methods. This study was a single-surgeon,

Aim. S. aureus and coagulase-negative staphylococci are the most frequent bacteria responsible for PJI. In patients with acute PJI (i.e. <1 month following the implantation), DAIR with exchange of removal components followed by a combination of antibiotics that includes rifampin (particularly rifampin+fluoroquinolone) are recommended. Unfortunately, some patients could not receive rifampin due to drug-drug interaction or stopped it due to an adverse event. Finally, it was unclear if the dose and the duration of rifampin influenced the prognosis. Method. We performed a
First Metatarsophalangeal joint fusion has been successfully used to treat Hallux rigidus. We have attempted to evaluate commonly used methods of fixation and joint preparation. To the best of our knowledge, this is the single largest comparative study on first MTPJ fusion. We aimed to evaluate the radiological union and revision rates. We included 409 consecutive MTPJ fusions performed in 385 patients. We collected demographic, comorbidities and complication data. We evaluated the radiographs for the status of the union. Logistic regression was used to calculate the Odds ratio (OR) of non-union for the collected variables. Our union rate was 91.4% (34/409). 29.4% of our non-unions were symptomatic (10/34). Hallux valgus showed a statistically significant relation to non-union (Odds ratio 9.33, p-value 0.017). Other potential contributing factors like sex (OR1.9, p-value 0.44), diabetes (OR 0, p-value 0.99), steroid use (OR 2.07, p-value 0.44), inflammatory arthritis (OR 0, p-value 0.99) and smoking (OR 2.69, p-value 0.34) did not attain statistical significance. Further, the methods of fixation like solid screws (OR 0, p-value 0.99), plate (OR 3.6, p-value 0.187) or cannulated screws (OR 0.09, p-value 0.06) showed no correlation with non-union. We compared two techniques of joint preparation and found no significant difference in union rates (Chi-Square 1.0426, p-value 0.30). Our crude cost comparison showed the average saving to the trust per year could be 33,442.50£ by choosing screws over plate. Only Hallux Valgus had a statistically significant relation to non-union. Solid screw could be economically the most viable option and a valid alternative.
Periprosthetic joint infection (PJI) causes significant morbidity. Methicillin sensitive Our hospital trust introduced MSSA screening and decolonisation prior to hip and knee arthroplasty in 2010. Data was prospectively collected since 2013, including all MSSA carriers, decolonisation treatment received, MSSA status at time of surgery and all PJIs. Prior to 2017 MSSA carriers received nasal mupirocin or neomycin, from August 2017 until August 2019 nasal octenidine was used. During the study period 15,958 primary hip and knee replacements were performed. 3,200 (20.1%) were MSSA positive at preoperative screening and received decolonisation treatment, 698 mupirocin, 1,210 neomycin and 1,221 octenidine. Mupirocin (89.1%) and neomycin (90.9%) were more effective at decolonisation than octenidine (50.0%, P<0.0001). There was no difference in S. aureus PJI rates (P=0.452). Of those negative at original screening 9.1% were positive on the day of surgery (1,164/12,758). MSSA decolonisation is an effective method to decrease PJI rates but there is little research into the best treatment. Both mupirocin and neomycin are more effective than octenidine at achieving MSSA decolonisation. There was poor correlation between the MSSA status after treatment and PJI rates. There is debate if treatment should be targeted by screening or if all patients she be treated without screening. Global decolonisation without screening is supported by the 26.7% of carriers that were negative at original screening in our study. Further research is needed comparing decolonisation treatments to reduce PJI rates and avoid the risk of drug resistance.
Frame configuration for the management of complex tibial fractures is highly variable and is dependent not only on fracture pattern and soft tissue condition but also surgeon preference. The optimal number of rings to use when designing a frame remains uncertain. Traditionally, larger, stiffer constructs with multiple rings per segment were thought to offer optimal conditions for bone healing, however, the concept of reverse dynamisation questions this approach. We compared clinical outcomes in 302 consecutive patients with tibial fractures treated in our unit with either a two-ring circular frame or a three-or-more-ring (3+) frame. The primary outcome measure was time spent in frame. Secondary outcomes were the incidence of malunion and the need for further surgical procedures to achieve bone union. The groups were evenly matched for age, co-morbidities, energy of injury mechanism, fracture classification, post-treatment alignment and presence of an open fracture.Introduction

Arthroscopic hip surgery is increasingly common in Australia. Hip arthroscopy is indicated for a range of diagnostic and therapeutic purposes, including labral tears, capsular laxity and femoral-acetabular impingement (FAI). Despite this, previous cohort studies aiming to characterise hip pathology seen on arthroscopic examination are mostly limited to patients with known diagnoses of FAI. Therefore, little is known of the native articular wear patterns encountered in other disease states. Therefore, we aimed to define common osteochondral wear patterns for a cohort of patients managed via hip arthroscopy. We retrospectively analysed intraoperative data for 1127 patients managed via hip arthroscopy between 2008 and 2013, for either therapeutic or diagnostic purposes. Intraoperative data was categorized by location (A-E as defined by Fontana et al. 2016) and chondral damage (0-4 scale as defined by Beck et al. 2005) with respect to both acetabulum and femoral head. Data for 1127 patients were included. Location of acetabular chondral pathology was variable with locations C1 and D1 representing the most common regions of damage. Labral tears predominated in locations C and D. Femoral chondral pathology was evenly distributed. The degree of femoral chondral injury was predominantly grade 1, whilst acetabular wear was evenly distributed. Large proportions of wear were observed at the peripheral superior and anterior regions of the lunate surface of the acetabulum in keeping with prior works. However, we observed higher rates of central wear and lower rates of grade 4 acetabular damage extending into superior/posterior zones, in our cohort. Our work characterises common articular wear patterns encountered at the time of hip arthroscopy. Further inquiry into the natural history of osteochondral lesions is needed to better understand and manage these conditions.
Diabetic foot problems are a common cause for hospitalisation in this group and up to 25% of diabetic patients will be affected. Prevalence of diabetes is rising, currently affecting 680000000 people worldwide. The enormity of this problem mandates any strategy that shortens therapeutic period and enhances success rates. Cerament G has been used in our unit as a treatment adjunct in diabetic foot treatment. Successful treatment is viewed as eradication of infection and a functional foot. Retrospective review of 40 months practice with 115 patients. Inclusion: all diabetic feet requiring surgery Cerament G used, protocol driven Microbiology pathway. Exclusion: Primary closure not possible. Cerament G not used. Outcome assessed in three groups: Total failure (further surgery required); slow to heal (healing by secondary intention); healed without problems. Healed 99 (eradication of infection and return to function), failure to heal 16 (success rate: 86.1%). Infection was the cause of failure in only in 2.6% (13 failures due to patient noncompliance or poor vascularity). Accepted success rate in treating osteomyelitis in diabetic feet is 68% (medical treatment only), combination of surgery and medical is 86%. Eradication of infection is the only end point return to function is not addressed. This study shows Cerament G with surgery/systemic antibiotics provides a 97.4% success rate. Therapeutic drivers in this field have been determined traditionally by Physicians and Vascular Surgeons (resection rather than reconstructive surgery.) Our assertion is that eradicating infection in a functionally useless foot is a waste of health resources. Our strategy is always the delivery of an intact functional foot residuum. Cerament G as an adjunct allows this goal in a cost-effective manner.
Acute hematogenous periprosthetic joint infection (AHI) is a diagnosis on the rise. The management is challenging and the optimum treatment is not clearly defined. The purpose of this study was to evaluate the characteristics of AHI, and to study risk factors affecting treatment outcome. We retrospectively analysed 44 consecutive episodes with AHI in a total hip or knee arthroplasty beween 2013 and 2020 at a single center. AHI was defined as abrupt symptoms of infection ≥ 3 months after implantation in an otherwise well functioning arthroplasty. We used the Delphi criteria to define treatment failure with a minimum of 1-year follow-up.Aim

There is still no clear consensus regarding which cup position might provide better functional performance for developmental dysplasia of the hip (DDH). This study aimed to evaluated the feasibility and efficacy of acetabular mirroring reconstruction for DDH in total hip arthroplasty (THA). The study reviewed 96 patients (96 hips) with unilateral Crowe type-II/III DDH undergoing either visualized navigation-assisted mirroring reconstruction with augment according to the rotation center and biomechanical structure of the contralateral normal hips (Mirroring group, 51 hips) or high hip center reconstruction (HHC group, 45 hips) in THA from 2020 to 2023. The functional and radiographic results were analyzed between the groups during a mean follow-up period of 27.5 and 28.9 months (a minimum follow-up of 12 months). The Harris hip score at the last follow-up significantly improved in both groups, while it was significantly higher in the mirroring group (P<0.001). In the HHC group, the rotation center height and greater trochanter height were significantly increased in the affected hip (P<0.001; P<0.001) and the abductor lever arm was significantly decreased in the affected hip compared to that in the contralateral normal hip (P<0.001), whereas in the mirroring group no significant statistical differences were observed between two sides. The limping occurred in 7 patients (13.7%) in the mirroring group and 14 patients (31.1%) in the HHC group (P=0.040). A multiple logistic regression demonstrated mirroring reconstruction could reduce the incidence of postoperative limping (P=0.020). Both mirroring and HHC reconstruction could improve the functional performance of THA, whereas mirroring reconstruction could offer superior biomechanical results and gait improvement as compared with HHC reconstruction, meeting the higher requirements of functional recovery.
Management of deformity involving limb length discrepancy (LLD) using intramedullary devices offers significant benefits to both patients and clinicians over traditional external fixation. Following the withdrawal of the PRECICE nail, the Fitbone became the primary implant available for intramedullary lengthening and deformity correction within our service. This consecutive series illustrates the advantages and complications associated with the use of this device, and describes a novel technique modification for antegrade intramedullary lengthening nails. A retrospective cohort review was performed of patient outcomes after treatment with the Fitbone nail at two tertiary referral limb reconstruction services (one adult, one paediatric) between January 2021 to December 2023. Aetiology, indications, initial and final LLD, use of concomitant rail assisted deformity correction (ORDER), removal time and healing index were assessed. Complications of treatment were evaluated and described in detail, alongside technique modifications to reduce the rate of these complications.Introduction

Introduction. National Institute for Health and Clinical Excellence (NICE) guidelines recommend the use of total hip replacement (THR) for displaced intracapsular fractured neck of femur (NOF) in cognitively intact patients who were independently mobile prior to the injury. The National Joint Registry for England and Wales (NJR) has collected data on THRs performed since 2003. This
To compare preoperative and postoperative Health Related Quality of Life (HRQoL) scores in operated Adolescent Idiopathic Scoliosis (AIS) patients with and without concomitant isthmic spondylolisthesis. A retrospective study of a prospective cohort of 464 individuals undergoing AIS surgery between 2008 and 2018 was performed. All patients undergoing surgery for AIS with a minimum 2-year follow-up were included. We excluded patients with prior or concomitant surgery for spondylolisthesis. HRQoL scores were measured using the SRS-22 questionnaire. Comparisons were performed between AIS patients with vs. without concomitant spondylolisthesis treated non-surgically. AIS surgery was performed for 36 patients (15.2 ±2.5 y.o) with concomitant isthmic spondylolisthesis, and 428 patients (15.5 ±2.4 y.o) without concomitant spondylolisthesis. The two groups were similar in terms of age, sex, preoperative and postoperative Cobb angles. Preoperative and postoperative HRQoL scores were similar between the two groups. HRQoL improved significantly for all domains in both groups, except for pain in patients with spondylolisthesis. There was no need for surgical treatment of the spondylolisthesis and no slip progression during the follow-up duration after AIS surgery. Patients undergoing surgical treatment of AIS with non-surgical management of a concomitant isthmic spondylolisthesis can expect improvement in HRQoL scores, similar to that observed in patients without concomitant spondylolisthesis.
Increased femoral head size reduces the rate of dislocation after total hip arthroplasty (THA). With the introduction of highly crosslinked polyethylene (HXLPE) liners in THA there has been a trend towards using larger size femoral heads in relatively smaller cup sizes, theoretically increasing the risk of liner fracture, wear, or aseptic loosening. Short to medium follow-up studies have not demonstrated a negative effect of using thinner HXLPE liners. However, there is concern that these thinner liners may prematurely fail in the long-term, especially in those with thinner liners. The aim of this study was to evaluate the long-term survival and revision rates of HXLPE liners in primary THA, as well as the effect of liner thickness on these outcomes. We hypothesized that there would be no significant differences between the different liner thicknesses. We performed a retrospective database analysis from a single center of all primary total hip replacements using HXLPE liners from 2010 and earlier, including all femoral head sizes. All procedures were performed by fellowship trained arthroplasty surgeons. Patient characteristics, implant details including liner thickness, death, and revisions (all causes) were recorded. Patients were grouped for analysis for each millimeter of PE thickness (e.g. 4.0-4.9mm, 5.0-5.9mm). Kaplan-Meier survival estimates were estimated with all-cause and aseptic revisions as the endpoints. A total of 2354 patients (2584 hips) were included (mean age 64.3 years, min-max 19-96). Mean BMI was 29.0 and 47.6% was female. Mean follow-up was 13.2 years (range 11.0-18.8). Liner thickness varied from 4.9 to 12.7 mm. Seven patients had a liner thickness <5.0mm and 859 had a liner thickness of <6.0mm. Head sizes were 28mm (n=85, 3.3%), 32mm (n=1214, 47.0%), 36mm (n=1176, 45.5%), and 40mm (n=109, 4.2%), and 98.4% were metal heads. There were 101 revisions, and in 78 of these cases the liner was revised. Reason for revision was instability/dislocation (n=34), pseudotumor/aseptic lymphocyte-dominant vasculitis associated lesion (n=18), fracture (n=17), early loosening (n=11), infection (n=7), aseptic loosening (n=4), and other (n=10). When grouped by liner thickness, there were no significant differences between the groups when looking at all-cause revision (p=0.112) or aseptic revision (p=0.116). In our cohort, there were no significant differences in all-cause or aseptic revisions between any of the liner thickness groups at long-term follow-up. Our results indicate that using thinner HXPE liners to maximize femoral head size in THA does not lead to increased complications or liner failures at medium to long term follow-up. As such, orthopedic surgeons can consider the use of larger heads at the cost of liner thickness a safe practice to reduce the risk of dislocation after THA when using HXLPE liners.

The average age of the patients for open decompression (63yrs +/− 11) compared to interspinous device (63yrs +/− 9) was equal. Male to female ratio for Open Vs ID [1.4:1 Vs 1.1:1] did not differ significantly (p = 0.39). The ASA grades were higher for the interspinous device group with an average of 2.5 compared to 2.1 in the open group. The length of anaesthetic was on average shorter for the interspinous devices, which included a higher proportion of 2 level decompressions. The average length of stay on average was identical at 1.3 days, complications were similar [5% Vs 7%] with patient satisfaction higher [81% Vs 68%], although statistically insignificant [p=0.79]
Interspinous device insertion is a less invasive procedure and can be carried out on patients with a higher anaesthetic risk, even being performed under sedation. It should be considered for patients with symptoms of LSS instead of open decompression as there is no effect on length of stay or complication rate and there is a trend toward a decrease in anaesthetic time with improved patient satisfaction in the short term.
Aim. Early fracture-related infections (FRIs) are a common entity in hospitals treating trauma patients. It is important to be aware of the consequences of FRI in order to be able to counsel patients about the expected course of their disease. Therefore, the aims of this study were to evaluate the recurrence rate, to establish the number of secondary surgical procedures needed to gain control of the initial infection, and to identify predictors for recurrence in patients with early FRI. Method. A
Dislocation is a major complication post total hip replacement (THR) and a common cause for revision. Jameson et al (2012) studied 35,000 cemented Exeter (Stryker) THRs demonstrating the risk of revision was significantly influenced by the acetabular component design. This led 3 surgeons in a single hospital group to make a mass move from using the hooded Exeter Low Profile (LP) cup to the better performing Contemporary Flanged (CF) component. The purpose of this study was to show whether this change was associated with a fall in dislocation rates. Locally held National Joint Registry data between 2010 and 2015 was used to ascertain implants used in all primary THRs by 3 experienced high volume surgeons. This was linked to local Hospital Episode Statistics to identify patients who had undergone closed or open reduction of a dislocated hip replacement in theatre.INTRODUCTION
PATIENTS/MATERIALS & METHODS
Ankle replacement is a major surgery with significant soft tissue dissection and bleeding. The skin quality is often poor in these patients due to age, edema, venous congestion, arteriopathy or previous procedures and soft tissue injury. The chances of wound infection increase with delayed wound healing. Absorbent non-adherent dressing (ABD) and VAC dressing applied in theatre after ankle replacement were assessed in a cohort of 147 patients with wound complications, pain, satisfaction and length of stay as outcome measures. 71 consecutive patients were treated with ABD post-operatively after ankle replacement. The practice was then changed to VAC dressings for 76 consecutive patients. 44 patients had additional procedures performed with ankle replacement (11 from ABD group and 33 from VAC group). Retrospective analysis of prospectively collected data was performed. All patients had daily pain score, wound status, hospital stay, satisfaction and range of movement recorded.Introduction

Aim. Diagnosing Fracture-Related Infections (FRI) is challenging. White blood cell (WBC) scintigraphy is considered the best nuclear imaging technique to diagnose FRI; a recent study by our group found a diagnostic accuracy of 92%. However, many centers use . 18. F-fluorodeoxyglucose positron emission tomography/computed tomography (. 18. F-FDG-PET/CT) which has several logistic advantages. Whether . 18. F-FDG-PET/CT has better diagnostic performance than white blood cell (WBC) scintigraphy is uncertain. Therefore, we aimed: 1) to determine the diagnostic performance of . 18. F-FDG-PET/CT for diagnosing FRI (defined as infection following an open fracture or fracture surgery) and 2) to determine cut-off values of standardized uptake values (SUV) that result in optimal diagnostic performance.

Aims. In the Netherlands, general practitioners (GPs) can request radiographs. After a radiologically diagnosed fracture, patients are immediately referred to the emergency department (ED). Since 2020, the Máxima Medical Centre has implemented a new care pathway for minor trauma patients, referring them immediately to the traumatology outpatient clinic (OC) instead of the ED. We investigated whether this altered care pathway leads to a reduction in healthcare consumption and concomitant costs. Methods. In this

Despite a relatively high incidence, there are few attempts at modelling impingement between the iliopsoas and acetabular component, and no attempts at modelling this in a representative cohort of subjects. The purpose of this study was to develop a novel computational model for quantifying the impingement between the iliopsoas and acetabular component and validate its utility in a case-controlled investigation.
