The aim of this retrospective cohort study was to investigate the reasons for total knee arthroplasty (TKA) revisions at a tertiary hospital over a four-year period. The study aimed to identify the primary causes of TKA revisions and shed light on the implications for patient care and outcomes. The study included 31 patients who underwent revisions after primary knee arthroplasty between January 2017 and December 2020. A retrospective approach was employed, utilizing medical records and radiological findings to identify the reasons for TKA revisions. The study excluded oncology patients to focus on non-oncologic indications for revision surgeries. Patient demographics, including age and gender, were recorded. Data analysis involved categorizing the reasons for revision based on clinical assessments and radiological evidence. Among the 31 patients included in the study, 9 were males and 22 were females. The age of the patients ranged from 43 to 81, with a median age of 65 and an interquartile range of 18.5. The primary reasons for TKA revisions were identified as aseptic loosening (10 cases) and prosthetic joint infection (PJI) (13 cases). Additional reasons included revision from surgitech hemicap (1 case), patella osteoarthritis (1 case), stiffness (2 cases), patella maltracking (2 cases), periprosthetic fracture (1 case), and patella resurfacing (1 case). The findings of this retrospective cohort study highlight aseptic loosening and PJI as the leading causes of TKA revisions in the examined patient population. These results emphasize the importance of optimizing surgical techniques, implant selection, and infection control measures to reduce the incidence of TKA revisions. Future research efforts should focus on preventive strategies to enhance patient outcomes and mitigate the need for revision surgeries in TKA procedures

Anterior cervical discectomy and fusion (ACDF) is a well-established spinal operation for cervical disc degeneration disease with neurological compromise. The procedure involves an anterior approach to the cervical spine with discectomy to relieve the pressure on the impinged spinal cord to slow disease progression. The prosthetic cage replaces the disc and can be inserted stand-alone or with an anterior plate that provides additional stability. The literature demonstrates that the cage-alone (CA) is given preference over the cage-plate (CP) technique due to better clinical outcomes, reduced operation time and resultant morbidity. This retrospective case-controlled study compared CA versus CP fixation used in single and multilevel anterior cervical discectomy and fusion for myelopathy in a tertiary centre in Wales. A retrospective clinico-radiological analysis was undertaken, following ACDF procedures over seven years in a single tertiary centre. Inclusion criteria were patients over 18 years of age with cervical myelopathy who had at least six-month follow-up data. SPSS was used to identify any statistically significant difference between both groups. The data were analysed to evaluate the consistency of our findings in comparison to published literature. Eighty-six patients formed the study cohort; 28 [33%] underwent ACDF with CA and 58 [67%] with CP. The patient demographics were similar in both groups, and fusion was observed in all individuals. There was no statistical difference between the two constructs when assessing subsidence, clinical complication (dysphagia, dysphonia, infection), radiological parameters and reoperations. However, a more significant percentage [43% v 61%] of patients improved their cervical lordosis angle with CP treatment. Furthermore, the study yielded that surgery to upper cervical levels results in a higher incidence of dysphagia [65% v 35%]. Finally, bony growth across the cage was observed on X-ray in 12[43%] patients, a unique finding not mentioned in the literature previously. Our study demonstrates no overall difference between the two groups, and we recommend careful consideration of individual patient factors when deciding what construct to choose

Currently, the consensus regarding subscapularis tendon repair during a reverse total shoulder arthroplasty (rTSA) is to do so if it is possible. Repair is thought to decrease the risk of dislocation and improve internal rotation but may also increase stiffness and improvement in internal rotation may be of subclinical benefit. Aim is to retrospectively evaluate the outcomes of rTSA, with or without a subscapularis tendon repair. We completed a retrospective review of 51 participants (25 without and 26 with subscapularis repair) who received rTSR by a single-surgeon using a single-implant. Three patient reported outcome measures (PROM) were assessed pre-operatively and post-operative at twelve months, as well as range of movement (ROM) and plain radiographs. Statistical analysis utilized unpaired t tests for parametric variables and Mann-Whitney U test for nonparametric variables. External Rotation ROM pre-operatively was the only variable with a significance difference (p=0.02) with the subscapularis tendon repaired group having a greater range. Pre- and post-operative abduction (p=0.72 & 0.58), forward flexion (p=0.67 & 0.34), ASES (p=0.0.06 & 0.78), Oxford (p=0.0.27 & 0.73) and post-operative external rotation (p=0.17). Greater external rotation ROM pre-operatively may be indicative of the ability to repair the subscapularis tendon intra-operatively. However, repair does not seem to improve clinical outcome at 12 months. There was no difference of the PROMs and AROMs between the subscapularis repaired and not repaired groups for any of the variables at the pre-operative or 12 month post operative with the exception of the external rotation ROM pre-operatively. We can conclude that from PROM or AROM perspective there is no difference if the tendon is repaired or not in a rTSR and indeed the patients without the repair may have improved outcomes at 12 months

Necrotizing soft tissue infection (NSTI) is a rapidly progressive infection that typically starts in the dermis and epidermis and spreads along soft tissue planes, penetrating subdermal layers and can lead to massive tissue necrosis resulting in severe morbidity and mortality. The aim of this case series was to describe the epidemiology and burden of NSTI's at a District Hospital servicing a South African urban settlement. This retrospective case series was performed at a single centre. Consecutive patients were identified following a clinical diagnosis for NSTI. Further laboratory pre-operative work up was standardized including: use of validated Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC scores) and Human Immunodeficiency Virus (HIV) status. All patients who underwent surgical debridement were captured on the Theatre Database (. www.medwebtools.org™. ). All patients received standardized perioperative, intra-operative and post-operative protocols for antibiotics, debridement and soft tissue closure or cover based on the severity of disease. Medical records, theatre notes, National Health Laboratory Service (NHLS) results and radiological results were captured for every patient. 28 patients (14 male, 14 female) presented with NSTI over a 3 year period (2021–2023). The mean age was 39.5 years. The most common organisms cultured were Streptococcus pyogenes (10 patients), Staphylococcus aureus (9 patients), Bacillus cereus (3 patients). This retrospective case series is an important study because it demonstrates some of the highest incidence of NSTI globally; however, the cause of this is yet to be determined. Our results show that having a high clinical index of suspicion; using the LRINEC score to assess severity and using a standardized antibiotic and peri-operative protocol with early soft tissue cover that NSTI's can be managed effectively with a reduction in patient morbidity and overall length of hospital stay

Abstract Background. The treatment of bone and joint infections (BJI) involving multi-drug resistant bacteria remains a challenge. MDR Staphylococcus epidermidis (MDRSE) clones, resistant to methicillin, clindamycin, levofloxacin, rifampicin and even linezolid, have been reported worldwide. The interest of delafloxacin (DFX), theoretically active on MRSA, remains to be evaluated with respect to MDRSE. Purpose. Our objective was to evaluate during a retrospective multicenter study the DFX minimal inhibitory concentrations (MICs) and compare its efficacy between ofloxacin-susceptible and ofloxacin-resistant S. epidermidis clinical strains involved in BJI. Methods. In this multicenter retrospective study (Reference centers from the West part of France, CRIOGO), 529 strains were collected mostly from BJI. DFX MICs were determined by using a 0.5 Mc Farland bacterial inoculum on Mueller-Hinton agar plates with gradient strips incubated for 24h at 35°C. For S. aureus, breakpoints differentiate skin and soft tissue infections from other infections. Breakpoints followed 2022 EUCAST criteria, with S. aureus values adopted for S. epidermidis. Results. Of the 529 strains collected, 355 were from prosthetic infections, 159 from synthetic infections and 15 from non-device infections. 152 strains were susceptible to ofloxacin (110 males vs 42 females) and 377 resistant (210 vs 167). As presented in Figure 1, all the ofloxacin-susceptible strains presented a DFX MIC ≤0.006mg/L. Resistant strains presented a double population distribution, with 3.7% categorized susceptible according to skin and soft tissues infections breakpoint, against 88.9% according to other breakpoint infections (0.016 or 0.25mg/L respectively). Conclusion. DFX shows excellent activity against ofloxacine-susceptible strains. Concerning the ofloxacin-resistant strains, more than 80% strains or less than 10% can be considered as DFX-susceptible depending on the breakpoints used. Further clinical studies are needed to validate the real breakpoints that must be used in MDRSE BJI, allowing a microbiological cure and a favourable clinical outcome.

Introduction. Flexor sheath infections require prompt diagnosis, and management with intravenous antibiotics and/or surgical washout followed by physiotherapy. Complication rates as high as 38% have been reported. Methods. A retrospective review was carried out of all patients between January 2014 and May 2021 attending with a suspected or confirmed diagnosis of flexor sheath infection. Age, gender, co-morbidities, cause of infection, management, and subsequent complications recorded. Results. Of 132 patients, 67% were male. Mean age was 50.8 years. A trend towards fewer presentations each year with animal bites, foreign bodies and penetrating trauma as the main cause of infection. 89% (n=117) required admission, 77% (n=101) underwent a surgical washout. 11% (n=15) were treated as an outpatient. 7% (n=9) suffered a complication. Discussion. Whilst flexor sheath washout continues to be the treatment of choice, 23% of patients were managed with intravenous antibiotics, 48% of these purely via an outpatient service. Our overall complication rate was 7%

The aim of this investigation is to firstly quantify the burden of disease, and secondly qualify the organisms being cultured during debridement to establish their sensitivities to available antibiotics. This study will also look at the concomitant burden of Human Immunodeficiency Virus (HIV) and Diabetes Mellitus (DM) in cases of hand sepsis, to establish whether these two disease processes require special consideration and treatment tailoring. The method employed to collect the data will be retrospective collection of patient information, using random sampling. Included patients will be adult patients who undergo debridement and have a sample registered on the National Health Laboratory System (NHLS). The daily intake sheet will be used to collect patients details and these details will then be used to collect results of intra-operative specimens using the NHLS. These patient details will also be used to check patients’ HIV results and HBA1c (Glycated Haemoglobin A1c) results. Majority of the specimens revealed Methicillin Sensitive Staphylococcus Aureus (MSSA), with a reassuringly low rate of Methicillin Resistant Staphylococcus Aureus (MRSA) when compared to international data. The yield of patients tested for HIV or DM was lower than expected, despite this being the standard of care. The projected impact of this study will be assessment of the current burden of disease and then clarification of our current management strategy, in order to assess if it would be possible to change to a more cost-effective antibiotic with a narrower spectrum of bacteria coverage. The potential exists to not only implement cost saving measures, but also promote antibiotic stewardship by decreasing the practice of empiric broad-spectrum antibiotic use

The aims of this study was to determine the incidence of malnutrition in children with supracondylar fractures. It was hypothesised that the presence of malnutrition will increase the severity type of fractures. The study was a retrospective, cross-sectional study at a single institution. Children between 0 years and 12 years of age, who sustained documented supracondylar fracture treated surgically as a result of low velocity trauma were included in the study. Patients who sustained high velocity trauma, who had known bone disorders or had incomplete chart data, were excluded from the study Data was captured from children's’ notes who have been treated surgically for supracondylar fractures from casualty, theatre and the clinic notes. The nutritional status of children and fracture grade were identified and the two sets of data were compared against each other to try to identify a possible relation between fracture severity and malnutrition. Data was analysed in STATA and 5% level of significance was used to signify statistically significant associations. 150 patients were identified and included in the study. The majority of patients reviewed were in the normal nutritional range according to their z-scores. The severity of the fracture was not only associated with a poorer nutritional status however children with high and low z-scores (over weight as well as undernourished children) had the more severe fracture patterns, while children with normal z-scores had a fracture patterns of varying severity. Children who were malnourished were more likely to sustain more severe fracture types. The results highlighted the need for all children to have a good nutritional status as this may play a role in preventing more complex fractures

Aim. Melioidosis is a significant public health problem in endemic regions such as India. Lack of awareness, predominant empiric antibiotic use reducing culture yields, morphotypic variability of cultures and frequent misidentification by automated blood culture systems, pose myriad challenges in diagnosis and treatment. Through this series, we present our experience of Hematogenous Osteomyelitis with Burkholderia pseudomallei. Method. This was a single centre, retrospective, observational study performed at a tertiary case hospital in Mumbai, India from June 2011 to June 2021. Results. The study comprised of 7 cases (6:1, M: F). Mean age was 53.7 years (5 to 75). All had an underlying co- morbidity or were immunosuppressed. 3 patients were misidentified by automated systems prior to presentation (e coli, burkholderia cepacieae, acinetobacter). Most common site of infection was femur (n= 3), followed by tibia and foot and ankle (n= 2, each). One had disseminated meliodosis involving the spleen, lymph nodes, pulmonary) in addition to involvement of bilateral feet and ankles. B. pseudomallei was identified in all following surgical debridement at our institute. Each patient underwent mean 2 procedures. 3 needed local rotation flap surgeries for wound cover. All were treated with ceftazidime along with trimethoprim- sulfamethoxazole (TMP- SMX) during the 6 week induction phase. TMP- SMX was continued for a further 6 months in the consolidation phase. All patients had infection remission at a mean 19.3 months follow up. There were no mortalities in our series. Conclusions. Clinically Burkholderia infections mimic other pyogenic infections, Gram-negative sepsis, tuberculosis and has been referred to as the “remarkable imitator” and the “mimicker of maladies”. Diabetes and alcoholism are risk factors. The need for diagnosing this entity is due to the fact that the septicemic form has a mortality rate that exceeds 90%. Melioidosis is frequently misidentified. A high clinical suspicion, communication with microbiologist, knowledge about the biochemical, cultural and phenotypic susceptibility patterns may help in optimising diagnosis. Adequate debridement coupled with targeted prolonged antibiotics help achieve good outcomes

The management of periprosthetic distal femur fractures is an issue of increasing importance for orthopaedic surgeons. Because of the expanding indications for total knee arthroplasty (TKA) and an aging population with increasingly active lifestyles there has been a corresponding increase in the prevalence of these injuries. The management of these fractures is often complex because of issues with obtaining fixation around implants and dealing with osteopenic bone or compromised bone stock. In addition, these injuries frequently occur in frail, elderly patients, and the early restoration of function and ambulation is critical in these patients. There remains substantial controversy with respect to the optimal treatment of periprosthetic distal femur fractures, with some advocating for Locked Plating (LP), others Retrograde Intramedullary Nailing (RIMN) and finally those who advocate for Distal Femoral Replacement (DFR). The literature comparing these treatments, has been infrequent, and commonly restricted to single-center studies. The purpose of this study was to retrospectively evaluate a large series of operatively treated periprosthetic distal femur fractures from multiple centers and compare treatment strategies. Patients who were treated operatively for a periprosthetic distal femur fracture at 8 centers across North America between 2003 and 2018 were retrospectively identified. Baseline characteristics, surgical details and post-operative clinical outcomes were collected from patients meeting inclusion criteria. Inclusion criteria were patients aged 18 and older, any displaced operatively treated periprosthetic femur fracture and documented 1 year follow-up. Patients with other major lower extremity trauma or ipsilateral total hip replacement were excluded. Patients were divided into 3 groups depending on the type of fixation received: Locked Plating, Retrograde Intramedullary Nailing and Distal Femoral Replacement. Documented clinical follow-up was reviewed at 2 weeks, 3 months, 6 months and 1 year following surgery. Outcome and covariate measures were assessed using basic descriptive statistics. Categorical variables, including the rate of re-operation, were compared across the three treatment groups using Fisher Exact Test. In total, 121 patients (male: 21% / female: 79%) from 8 centers were included in our analysis. Sixty-seven patients were treated with Locked Plating, 15 with Retrograde Intramedullary Nailing, and 39 were treated with Distal Femoral Replacement. At 1 year, 64% of LP patients showed radiographic union compared to 77% in the RIMN group (p=0.747). Between the 3 groups, we did not find any significant differences in ambulation, return to work and complication rates at 6 months and 1 year (Table 1). Reoperation rates at 1 year were 27% in the LP group (17 reoperations), 16% in the DFR group (6 reoperations) and 0% in the RIMN group. These differences were not statistically significant (p=0.058). We evaluated a large multicenter series of operatively treated periprosthetic distal femur fractures in this study. We did not find any statistically significant differences at 1 year between treatment groups in this study. There was a trend towards a lower rate of reoperation in the Retrograde Intramedullary Nailing group that should be evaluated further with prospective studies.

Routine post-operative bloods following all elective arthroplasty may be unnecessary. This retrospective cohort study aims to define the proportion of post-operative tests altering clinical management. Clinical coding identified all elective hip or knee joint replacement under Hawkes Bay District Health Board contract between September 2019-December 2020 (N=373). Uni-compartmental and bilateral replacements, procedures performed for cancer, and those with insufficient data were excluded. Demographics, perioperative technique, and medical complication data was collected. Pre- and post-operative blood tests were assessed. Outcome measures included clinical intervention for abnormal post-operative sodium (Na), creatinine (Cr), haemoglobin (Hb), or potassium (K) levels. A cost-benefit analysis assessed unnecessary testing. 350 patients were Included. Median age was 71 (range 34-92), with 46.9% male. Only 26 abnormal post-operative results required intervention (7.1%). 11 interventions were for low Na, 4 for low K, and 4 for elevated Cr. Only 7 patients were transfused blood products. Older age (p=0.009) and higher ASA (p=0.02) were associated with intervention of any kind. Abnormal preoperative results significantly predicted intervention for Na (p<0.05) and Cr (p<0.05). All patients requiring treatment for K used diuretic medication. Preoperative Hb level was not associated with need for transfusion. Overall, there were 1027 unnecessary investigations resulting in $18,307 excess expenditure. Our study identified that the majority of elective arthroplasty patients do not require routine postoperative blood testing. We recommend investigations for patients with preoperative electrolyte abnormality, those taking diuretics, and patients with significant blood loss noted intra-operatively. In future, a larger, randomised controlled trial would be useful to confirm these factors

Introduction. External fixators are attached to bones with percutaneous pins and wires inserted through soft tissues and bone increasing the risk of infections. Such infections compromise patient outcomes e.g., through pin loosening or loss, failure of fixator to stabilise the fracture, additional surgery, increased pain, and delayed mobilisation. These infections also impact the healthcare system for example, increased OPD visits, hospitalisations, treatments, surgeries and costs. Nurses have a responsibility in the care and management of patients with external fixators and ultimately in the prevention of pin-site infection. Yet, evidence on best practices in the prevention of pin-site infection is limited and variation in pin-site management practices is evident. Various strategies are used for the prevention of pin-site infection including the use of different types of non-medicated and medicated wound dressings. The aim of this retrospective study was to investigate the use of dry gauze or iodine tulle dressings for the prevention of pin-site infections in patients with lower limb external fixators. Methodology. A retrospective study of patients with lower limb external fixators who attended the research site between 2015–2022. Setting & Sample: The setting was the outpatient's (OPD) orthopaedic clinic in a University Teaching Hospital in Dublin, Ireland. Eligibility Criteria:. Over the age of 16, treated with an Ilizarov, Taylor Spatial frame (TSF) or Limb Reconstruction System (LRS) external fixators on lower limbs,. Pin-sites dressed with dry gauze or iodine tulle,. Those with pre-existing infected wounds close to the pin site and/or were on long term antibiotics were excluded. Follow Up Period: From time of external fixator application to first pin-site infection or removal of external fixator. Outcome Assessment: The primary outcome was pin-site infection, secondary outcomes included but were not limited to frequency of pin-site infection according to types of bone fixation, frequency of pin/wire removal and hospitalisation due to infection. Data analysis: IBM SPSS Version 25 was used for statistical analysis. Descriptive and inferential statistics were conducted as appropriate. Categorical data were analysed by counting the frequencies (number and percentages) of participants with an event as opposed to counting the number of episodes for each event. Differences between groups were analysed using Chi-square test or Fisher's exact test, where appropriate. Continuous variables were reported using mean and standard deviations and difference analysed using a two-sample independent t-test or non-parametric test (Mann-Whitney), where appropriate. Using Kaplan-Meier, survival analysis explored time to development of infection. Ethical approval: granted by local institute Research Ethics Committee on 12th March 2018. Results. During the study period, 97 lower limb external fixators were applied with 43 patients meeting the study eligibility criteria. The mean age was 38 (SD 14.1; median 37) and the majority male (n=32, 74%). At least 50% (n=25) of participants had an IIizarov fixator, with 56% (n=24) of all fixators applied to the tibia and fibula. Pin/wire sites were dressed using iodine (n=26, 61%) or dry gauze dressings (n=15, 35%). The mean age of participants in the iodine group was significantly higher than the dry gauze group (p=.012). The only significant difference between the iodine and dry gauze dressing groups at baseline was age. A total of 30 (70%) participants developed a pin-site infection with 26% (n=11) classified as grade 2 infection. Clinical presentation included redness (n=18, 42%), discharge (n=16, 37%) and pain (n=15, 35%). Over half of participants were prescribed oral antibiotics (n=28, 65%); one required intravenous antibiotics and hospitalization due to pin-site infection. Ten (23%) participants required removal of pin/wires; two due to pin-site infection. There was no association between baseline data and pin-site infection. The median time to developing an infection was 7 weeks (95%, CI 2.7 to 11.29). Overall, there were 21 (81%, n=26) pin-site infections in the iodine group and nine (60%, n=15) in the dry gauze group, difference in proportion and relative risk between the dressing groups were not statistically significant (RR 1.35, 95% CI 0.86–2.12; p= .272). There was no association between baseline data, pin-site infection, and type of dressing. Conclusions. At the research site, patients are referred to the OPD orthopaedic clinic from internal and external clinical sites e.g., from Hospital Consultants, General Practitioners and occasionally from multidisciplinary teams, throughout Ireland. Our retrospective observation study found that 97 lower limb external fixators were applied over a seven-year period which is lower than that reported in the literature. However, the study period included the COVID pandemic years (2020 and 2021) which saw a lower number of external fixators applied due to lack of theatre availability, cancelled admissions and social/travel restrictions that resulted in fewer accidents and lower limb trauma cases requiring external fixator application. The study highlighted a high infection rate with 70% of participants developing pin-site infection which is in keeping with findings reporting in other studies. Our study showed that neither an iodine nor dry gauze dressing was successful in preventing pin-site infection. In the iodine group 81% of participants developed infection compared to 60% in the dry gauze group. Given the lack of difference between the two groups consideration needs to be given to the continued use of iodine dressings in the prevention of pin-site infection. Pin-site infections result in a high portion of participants being prescribed antibiotics and, in an era, that stresses the importance of antimicrobial stewardship there is a need to implement effective infection prevention and control strategies that minimise infection. Further research is therefore needed to investigate more innovative medicated dressings such as those that contain anti-microbial or anti-bacterial agents

In reverse shoulder arthroplasty (RSA), a high complication rate is noted in the international literature (24.7%), and limited local literature is available. The complications in our developing health system, with high HIV, tuberculosis and metabolic syndrome prevalence may be different from that in developed health systems where the literature largely emanates from. The aim of this study is to describe the complications and complication rate following RSA in a South African cohort. An analytical, cross-sectional study was done where all patients’ who received RSA over an 11 year period at a tertiary hospital were evaluated. One-hundred-and-twenty-six primary RSA patients met the inclusion criteria and a detailed retrospective evaluation of their demographics, clinical variables and complication associated with their shoulder arthroplasty were assessed. All fracture, revision and tumour resection arthroplasties were excluded, and a minimum of 6 months follow up was required. A primary RSA complication rate of 19.0% (24/126) was noted, with the most complications occurring after 90 days at 54.2% (13/24). Instability was the predominant delayed complication at 61.5% (8/13) and sepsis being the most common in the early days at 45.5% (5/11). Haematoma formation, hardware failure and axillary nerve injury were also noted at 4.2% each (1/24). Keeping in mind the immense difference in socioeconomical status and patient demographics in a third world country the RSA complication rate in this study correlates with the known international consensus. This also proves that RSA is still a suitable option for rotator cuff arthropathy and glenohumeral osteoarthritis even in an economically constrained environment like South Africa

Shoulder septic arthritis is uncommon and frequently misdiagnosed, resulting in severe consequences. This study evaluated the demographics, bacteriological profile, antibiotic susceptibility, treatment regimens, and clinical outcomes. This is a 10-year retrospective observational analysis of 30 patients (20 males and 10 females) who were treated for septic arthritis of the shoulder. The data collecting process utilised clinical records, laboratory archives, and x-ray archives. We gathered demographic information, pre- and post-intervention clinical data, serum biochemical markers, and the results of imaging examinations. All patients had a surgical arthrotomy and joint debridement in the operating room, and specimens were taken for culture and sensitivity testing. The specimens were cultivated for at least seventy-two hours. Shoulder joint ranges of motion, comorbidities, and the presence of osteomyelitis were assessed clinically to determine the outcome. All statistical analyses were conducted using the STATA 17 statistical software. Analysis of correlation between categorical variables was performed using the chi-squared test. The majority of the study patients were black Africans (97%). The age range of the group was from 8 days to 17 years. At presentation, 33% of patients had a low-grade fever, whereas the majority (60%) had normal body temperature. The average length of symptoms was 3.9 days (ranged from 1 day to 15 days), and the majority of patients had an increased white cell count (83%) and C-reactive protein (98%). There was accumulation of fluid in the joint of all individuals who received shoulder ultrasound imaging. We noted a significant incidence of gram-positive cocci, which were mostly susceptible to first-line antibiotics. Shoulder stiffness affected 63% of patients and chronic osteomyelitis affected 50% of individuals. Neither the severity nor the duration of the symptoms was related to an increased risk of osteomyelitis. The results of this study revealed that the clinical characteristics and bacterial profile of septic arthritis of the shoulder conform to typical patterns. The likelihood of osteomyelitis and an unfavourable prognosis is considerable

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 retrospective cohort study of patients aged 18–55 years old admitted under our orthopaedic unit between 1st of April 2009 and 31st of October 2013 with PM ankle fractures was performed. Inclusion criteria were that all patients must mobilise independently pre-trauma, have no pre-existing ankle pathologies, and had satisfactory bimalleolar and syndesmotic stabilisation. Open fractures, talar fractures, calcaneal fractures, pilon fractures, subsequent re-injury and major complications were excluded. All PM fragments were unfixated. Clinical outcomes were evaluated using Foot and Ankle Ability Measure (FAAM) with activities of daily living (ADL) and sports subscale, visual analogue scale (VAS) and patient satisfaction ratings. Osteoarthrosis was assessed using modified Kellgren-Lawrence scale on updated weightbearing ankle radiographs. 61 participants were included. Mean follow-up was 10.26 years. Average PM size was 16.19±7.39%. All participants were evaluated for clinical outcomes, demonstrating good functional outcomes (FAAM-ADL 95.48±7.13; FAAM-Sports 86.39±15.52) and patient satisfaction (86.16±14.42%), with minimal pain (VAS 1.13±1.65). Radiographical outcomes were evaluated in 52 participants, showing no-to-minimal osteoarthrosis in 36/52 (69.23%), mild osteoarthrosis in 14/52 (26.92%) and moderate osteoarthrosis in 2/52 (3.85%). Clinical outcomes were not associated with PM fragment size, post-reduction step-off, dislocation, malleoli fractured or syndesmotic injury. PM step-off and dislocation were associated with worse radiographical osteoarthrosis. Other published medium-to-long term studies reported overall good outcomes, with no differences after small fragment fixation. The unfixated smaller posterior malleolus fragment demonstrated overall satisfactory clinical and radiographical outcomes at 10-year follow-up and may be considered a valid treatment strategy

Aims. Bone and joint infections cause significant morbidity, often requiring combination medical and surgical treatment. The presence of foreign material reduces the number of organisms required to cause an infection. The aim of this study was to assess whether there was a difference in the species of organism identified on culture in osteomyelitis compared to prosthetic joint infection. Method. This was a retrospective observational cohort study of patients that had surgical intervention for prosthetic joint infection or osteomyelitis with positive microbial culture between 2019 and 2022. Data including patient demographics, site of injury, BACH score for osteomyelitis and JS-BACH score for prosthetic joint infection, organism classification and antibiotic resistance to vancomycin and gentamicin were extracted from the medical record. Logistic and multiple regressions were used to adjust for potential confounding variables. Results. A total of 445 patients were included in the study; 267 patients with osteomyelitis or fracture-related infection and 177 patients with prosthetic joint infection. The patients with prosthetic joint infection were older (Mean age 70 for PJI; IQR 60-77 vs 56 for OM/FRI; IQR 39-64), more likely to be female (55.6% vs 26.2%) and had a higher BMI and ASA compared to those with osteomyelitis. Symptom duration tended to be longer in osteomyelitis/FRI (p<0.001). Staphylococcus aureus was the most common pathogen isolated in both osteomyelitis (155/267 (58.1%)) and prosthetic joint infection (85/177 (48.9%), followed by other Gram negative pathogens with 77/267 (28.8%) in osteomyelitis and 48/177 (27.1%) in prosthetic joint infection. On multivariate analysis, there was no difference between the rate of Staphylococcus aureus infection between the two groups. The rate of polymicrobial infection was higher in patients with osteomyelitis (92/267 (34.5%)) compared to prosthetic joint infection (38/177 (23.7%), however after adjustment for confounders there was no difference, p = 0.842. There was no difference in the presence of gentamicin resistant organisms or vancomycin resistant Gram positive organisms in osteomyelitis compared to prosthetic joint infection. Conclusion. Causative pathogens are similar in these two common forms of bone and joint infection. There was no significant difference in the identification, presence of polymicrobial infection or gentamicin and vancomycin resistance in organisms isolated in osteomyelitis compared to prosthetic joint infection. This may have implications for empiric antibiotic choice and local antibiotic therapy in the management of bone and joint infection

The reverse total shoulder replacement (rTSR) has excellent clinical outcomes and prosthesis longevity, and thus, the indications have expanded to a younger age group. The use of a stemless humeral implant has been established in the anatomic TSR; and it is postulated to be safe to use in rTSR, whilst saving humeral bone stock for younger patients. The Lima stemless rTSR is a relatively new implant, with only one paper published on its outcomes. This is a single-surgeon retrospective matched case control study to assess short term outcomes of primary stemless Lima SMR rTSR with 3D planning and Image Derived Instrumentation (IDI), in comparison to a matched case group with a primary stemmed Lima SMR rTSR with 3D planning and IDI. Outcomes assessed: ROM, satisfaction score, PROMs, pain scores; and plain radiographs for loosening, loss of position, notching. Complications will be collated. Patients with at least 1 year of follow-up will be assessed. With comparing the early radiographic and clinical outcomes of the stemless rTSR to a similar patient the standard rTSR, we can assess emerging trends or complications of this new device. 41 pairs of stemless and standard rTSRs have been matched, with 1- and 2-year follow up data. Data is currently being collated. Our hypothesis is that there is no clinical or radiographical difference between the Lima stemless rTSR and the traditional Lima stemmed rTSR

Acromioclavicular joint injuries are one of the most common injuries in the shoulder girdle complex. Surgical management is considered based on patient profile, level of activity, pain, and classification of injury. To date, a vast array of surgical techniques have been proposed and described in the literature, a possible reason being that the optimal solution is still uncertain. The aim of this study is to determine the efficacy of an alternative surgical technique. This study is a retrospective case series of 80 patients that have been operated by a single surgeon over a period of 6 years. A novel surgical technique, the ‘BiPOD method’, was applied where a synthetic artificial ligament (LARS®) is used to reconstruct and reduce the acromioclavicular joint. The technique is done in a reproducible manner, where a single continuous artificial ligament is used to reduce and reconstruct both, the coracoclavicular and acromioclavicular ligament complexes to achieve bidirectional stability. Patients were followed-up postoperatively, either clinically where possible or telephonically. The Acromioclavicular Joint Instability Score (ACJI) and radiographic measurements were used to determine the clinical and surgical outcome of the surgery. Radiographic parameters, measuring the reduction of the coracoclavicular- and acromioclavicular joint, were analysed and documented. The results showed marked improvement in both, the coracoclavicular distance and acromioclavicular distance. Clinically, using the ACJI scoring system, the patients reported substantial improvement in pain and function. Complications were recorded but were insignificant. The BiPOD surgical technique, making use of an artificial LARS® ligament, has proven acceptable outcomes in the surgical management of acromioclavicular joint dislocations

Introduction. Sheffield Children's Hospital specialises in limb lengthening for children. Soft tissue contracture and loss of range of motion at the knee and ankle are common complications. This review aims to look at therapeutic techniques used by the therapy team to manage these issues. Materials & Methods. A retrospective case review of therapy notes was performed of femoral and tibial lengthening's over the last 3 years. Included were children having long bone lengthening with an iIntramedullary nail, circular frame or mono-lateral rail. Patients excluded were any external fixators crossing the knee/ankle joints. Results. 20 tibial and 25 femoral lengthening's met the inclusion criteria. Pathologies included, complex fractures, limb deficiency, post septic necrosis and other congenital conditions leading to growth disturbance. All patients had issues with loss of motion at some point during the lengthening process. The knee and foot/ankle were equally affected. Numerous risk factors were identified across the cohort. Treatment provided included splinting, serial casting, bolt on shoes, exercise therapy, electrical muscle stimulation and passive stretching. Conclusions. Loss of motion in lower limb joints was common. Patients at higher risk were those with abnormal anatomy, larger target lengthening's, poor compliance or lack of access to local services. Therapy played a significant role in managing joint motion during treatment. However, limitations were noted. No one treatment option gave preferential outcomes, selection of treatment needed to be patient specific. Future research should look at guidelines to aid timely input and avoid secondary complications

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
