INTRODUCTION. There is historical evidence of increased incidence of transitional cell tumours of the renal tract in workers exposed to high levels of metal ions. This study was designed to establish any correlation between Metal on metal bearing hip arthroplasty and TCC. METHODS. A prospective North-East database of 2900 Urology/Oncology cases was compared with the Freeman Joint Registry, which is a prospective database of all Arthroplasty performed since 2001 to establish any correlation with TCC. After comparing the Urology database with the Freeman Joint Registry from 2001 to 2011, a group of patients was identified who underwent hip replacement and had TCC of bladder. The incidence of TCC was calculated in patients who had metal on metal hip replacement and those who had metal on poly hip replacement. On comparing both the groups no significant difference in incidence of TCC of bladder was recorded. RESULTS. No increase in the incidence of transitional cell carcinoma was observed in patients who had metal on metal hip replacements compared to the one who had metal on polyethylene hips

Sacral fractures are often underdiagnosed, but are frequent in the setting of pelvic ring injuries. They are mostly caused by high velocity injuries or they can be pathological in aetiology. We sought to assess the clinical outcomes of the surgically treated unstable sacral fractures, with or without neurological deficits. unstable sacral fractures were included in the study. Single centre, prospectively collected data, retrospective review of patients who sustained vertically unstable fractures of the sacrum who underwent surgical fixation. out of a total of 432 patients with pelvis and acetabulum injuries. fifty six patients met the inclusion criteria. 18 patients had sustained zone one injuries. 14 patients had zone 2 injuries and 10 patients had zone 3 injurie. Operative fixation was performed percutaneously using cannulated screws in 18 patients.. Open fixation of the sacrum using the anterior approach in 6 patients. Posterior approach was indicates in all 10 of the zone 3 injuries of the sacrum. While in 4 patients, combined approaches were used. 3 patients had decompression and spinopelvic fixation. Neurological deficits were present in 16% of the patients. 2 patients presented with neurgenic bladder. Of the 4 patients who had neurological fall out, 3 resolved with posterior decompression and posterior fixation. All 4 neurological deficits were due to taction or compression of the nerve roots. No hardware failures or non unions observed. The rate of neurological deficit was related more to the degree of pelvic ring instability than to a particular fracture pattern. Low rates of complications and successful surgical treatment of sacral fractures is achiavable. Timeous accurate diagnosis mandatory

Objective. To investigate the relationship between the pattern of pelvic or acetabular fracture, and bladder injuries. Methods. A total of 173 patients admitted at our Academic Hospital from January 2006 to March 2012 with cystograms done for pelvic or acetabular fractures were studied retrospectively. Records of pelvic X-Rays, CT scans and cystograms were reviewed. Tile's classification and Young & Burgess classification were used for pelvic fractures and Judet & Letournel classification system for acetabular fractures. Results. Out of 173 patients 16% had bladder injuries of which 22% were intra-peritoneal and 70% were extra-peritoneal. The bladder injuries mostly occurred among male patients; 16 males compared to 9 female patients. Out of the 21 fractures of the acetabulum only 2 sustained bladder injury and they were secondary to gunshot wounds. Lateral compression fractures accounted for 67% of bladder injuries. Motor vehicle accidents were the leading mechanism of injury accounting for 117 patients in total and 81% of those with bladder injuries. Among the patients with bladder rupture 55% had at least 3 rami involved and only one patient (4%) with 1 ramus involved had a bladder injury. Overall 44 (34%) of patients with 3 or more rami fractured had bladder injury. Conclusion. Bladder injury appears to be related to the mechanism of injury. We recommend that a cystogram be done routinely when a patient presents with a type III lateral compression fracture. In isolated acetabulum fractures, single ramus fractures and lateral compression type I fractures, request for cystogram should be correlated with clinical signs and symptoms, and not done routinely.

Aim. Patient quality of life (QoL) in untreated bone infection was compared to other chronic conditions and stratified by disease severity. Method. Patients referred for treatment of osteomyelitis (including fracture related infection) were identified prospectively between 2019 and 2023. Patients with confirmed infection completed the EuroQol EQ-5D-5L questionnaire. Clinicians blinded to EQ-index score, grouped patients according to JS-BACH Classification into ‘Uncomplicated’, ‘Complex’ or ‘Limited treatment options’. A systematic review of the literature was performed of other conditions that have been stratified using EQ-index score. Results. 257 patients were referred, and 219 had suspected osteomyelitis. 196 patients had long bone infection and reported an average EQ-index score of 0.455 (SD 0.343). 23 patients with pelvic osteomyelitis had an average EQ-index score of 0.098 (SD 0.308). Compared to other chronic conditions, patients with long-bone osteomyelitis had worse QoL when compared to different types of malignancy (including bladder, oropharyngeal, colorectal, thyroid and myeloma), cardiorespiratory disease (including asthma, COPD and ischaemic heart disease), psychiatric conditions (including depression, pain and anxiety), endocrine disorders (including diabetes mellitus), neurological conditions (including Parkinson's disease, chronic pain and radiculopathy) and musculoskeletal conditions (including osteogenesis imperfecta, fibrous dysplasia and x-linked hypophosphataemic rickets). QoL in long-bone infection was similar to conditions such as Prada-Willi syndrome, Crohn's disease and juvenile idiopathic arthritis. Patients who had a history of stroke or multiple sclerosis reported worse QoL scores compared to long-bone infection. Patients who had pelvic osteomyelitis gave significantly lower QoL scores when compared to all other conditions that were available for comparison in the literature. In long bone infection, 41 cases (21.0%) were classified as ‘Uncomplicated’, 136 (69.4%) as ‘Complex’ and 19 (9.7%) as ‘Limited treatment options available’. Within classification stratification, patients with ‘Uncomplicated’ long bone infections reported a mean EQ-index score of 0.618 (SD 0.227) which was significantly higher compared to ‘Complex’ (EQ-index: 0.410 SD 0.359, p=0.004) and ‘Limited treatment options available’ (EQ-index: 0.400 SD 0.346, p=0.007). Conclusions. Bone and joint infections have a significant impact on patient quality of life. It is much worse when compared to other common chronic conditions, including malignancy, cardiovascular and neurological diseases. This has not been previously reported but may focus attention on the need for more investment in this patient group

The purpose of this study is to find the clinical outcome of decompression of Cauda Equina presenting late in the course of disease. There were 33 males and 17 females with average age of 48 years, ranging from 25 to 85 years. All patients presented to us with a fully developed Cauda Equina syndrome (CES). All of them presented late with mean delay of 12.2 days. Time interval between bladder and bowel dysfunction and admission to hospital varied from 1 to 35 days. The average follow-up was 34.5 months, ranging from 12 to 60 months. There was no statistically significant difference in time of delay in surgery between the recovered and non-recovered group as tested by Student's t test. But there was a statistically significant positive correlation between duration taken for total recovery and delay in surgery. Anal wink as a predictor of bladder and bowel recovery also showed statistical significance, as patients with an absence had a poorer prognosis for bladder recovery. The result of surgery in CES is not as dramatic and fast as seen after routine disc surgery. Some improvement can be expected with decompression even in those patients presenting late and results are not universally poor as previously thought. The treating physicians of such patients should be aware that the recovery in this group of patients can take an exceptionally long time and hence should involve in constant reassurance and rehabilitation of the patient. Presence of anal wink is a very good predictor of bladder and bowel recovery

Introduction. Urinary catheterisation can cause bacteraemia and therefore may be associated with a risk of infection in hip and knee arthroplasty. However postoperative urinary retention can be distressing for the patient. This study investigates the factors that might predict the need for postoperative catheterisation in order to help develop a protocol to decide who should be electively catheterised. Methods. A prospective blinded study of 128 consecutive patients undergoing lower limb arthroplasty was carried out. No patient underwent perioperative catheterisation. Data obtained included sex, age, joint (hip or knee replacement), prostate score (IPSS), previous urinary retention, comorbidities and residual bladder volume after attempted complete voiding measured using an ultrasound bladder scanner. The type of anaesthesia and the requirement for urinary catheterisation postoperatively were recorded. Predictive risk factors were identified using binary logistic regression, and expressed as odds ratios (OR) and 95% confidence intervals (CI). Results. The mean age was 69.5 years (SD 8.9). There were 56 males and 72 females. 38 patients (30%) required postoperative catheterisation. Logistic regression identified the following predictive risk factors: bladder scan volume per ml increase (OR 1.006; CI 1.000–1.012); male sex (OR 5.51; CI 2.01–15.16); previous catheter (OR 4.26; CI 1.53–11.82); spinal/epidural/combined spinal epidural (CSE) anaesthesia (OR 6.78; CI 1.75–26.32); moderate IPSS score (OR 5.15; CI 1.73–15.37); severe IPSS score (OR 3.53; CI 0.605–20.54). The specificity of our model is 91%, the positive predictor value 71% and negative predictor value 82%. Discussion. Post-voiding bladder scan volume (1ml increase = 0.6% increased risk), male sex, history of retention, medium or high IPSS score and an epidural, spinal or CSE anaesthetic are independent risk factors that can be used preoperatively to predict the likelihood of postoperative retention

Urinary catheterisation may be associated with a risk of infection in hip and knee arthroplasty, however post-operative urinary retention can be distressing for the patient. This study investigates the factors that might predict the need for post-operative catheterisation. A prospective blinded study of 128 consecutive patients undergoing lower limb arthroplasty was carried out. Data obtained included sex, age, joint (hip or knee), prostate score (IPSS), previous urinary retention, co-morbidities and residual bladder volume after attempted complete voiding measured using an ultrasound bladder scanner. Anaesthetic type and requirement for urinary catheterisation postoperatively were recorded. Predictive risk factors were identified using binary logistic regression, and expressed as odds ratios (OR) and 95% confidence intervals (CI). The mean age was 69.5 years. There were 56 males and 72 females. 38 patients (30%) required post-operative catheterisation. Logistic regression identified the following predictive risk factors: bladder scan volume per ml increase (OR 1.006; CI 1.000–1.012); male sex (OR 5.51; CI 2.01–15.16); previous catheter (OR 4.26; CI 1.53–11.82); spinal/epidural/combined spinal epidural anaesthesia (OR 6.78; CI 1.75–26.32); moderate IPSS score (OR 5.15; CI 1.73–15.37); severe IPSS score (OR 3.53; CI 0.605–20.54). Our model specificity is 91%, positive predictor value 71% and negative predictor value 82%

Introduction. Neurological involvement occurs in 10-30% cases of caries spine. Surgical debridement and stabilisation is needed to decompress the cord and prevent progression of deformity. This prospective study was undertaken to determine the efficacy of operative treatment in the management and neurological recovery in patients with caries spine with neural deficit. Material & methods. 20 patients, 14 male, 6 female, were included and followed up for 1 year after surgery. The mean age was 39.45 years. 10 patients had complete paraplegia and 9 patients had paraparesis. 1 patient with cervical involvement had quadriplegia. Anterior decompression and stabilisation was done in all the cases. Objective of surgery was adequate debridement of diseased foci, decompression of cord and stabilisation of spine with correction of deformity. In 19 (95%) patients there with thoraco-lumbar involvement. This was addressed with a titanium mesh cage filled with impacted bone graft and supplemented with 2 Moss Miami screws and a rod construct. In the cervical spine, cervical spine locking plate was used for stabilisation after decompression and bone grafting (tricortical iliac crest graft). Results. Fifteen patients had complete and 5 patients had incomplete neurologic recovery. Neurological recovery started as early as first post-op week (range 3 days to 12 weeks). The ASIA motor score improved from 60.80 (60.80 +/− 20.206) before surgery to 73.55 (73.55 +/− 13.828) at 1 month and 95.30 (95.30+/−11.934) at 6 months after surgery. The ASIA sensory score improved from 173.30 (173.30 +/− 50.689), to 186.85 (186.65 +/− 37.452) at one month and 218.45 (218.45 +/−11.843) at 6 months. All 8 patients with bladder and bowel involvement recovered normal bladder and bowel functions at 6 months. There was no recurrence of infection. Bony fusion was achieved in all patients and there were no implant failures. Conclusion. Anterior debridement, decompression, stabilisation and anti-tubercular chemotherapy resulted in neurological recovery in the majority of the patients

Aim. Posttraumatic pelvic-osteomyelitis is one of the most serious complications after pelvic-fractures. The necessary extensive surgical debridement as part of interdisciplinary treatment is complicated by the possible persistence of pelvic instability. The aim of this study was to determine the outcome and outline the course of treatment after early posttraumatic pelvic bone infections due to type-C pelvic ring injuries. Method. In a retrospective cohort study (2005–2015) all patients with pelvic-osteomyelitis within six weeks of surgical stabilization of a type-C pelvic-fracture were assessed. Microbiological results, risk factors, course of treatment and functional long-term outcome using the Orlando-Pelvic-Score were analyzed. Results. A total of 18 patients (age 43.7 years; Body-Mass-Index 27.9 kg/m2; ASA-physical-status 1.8; Injury-Severity-Score 38) developed a pelvic-osteomyelitis within an average of 27 days after internal surgical stabilization of a type-C pelvic injury (AO-type C1: 10, C2: 4, C3: 4). Os pubis was affected in 7 and Os ilium in 11 cases. In addition to the pelvic-fracture, major vascular injuries occurred in 8, nerve injuries in 9, and intestinal and/or bladder ruptures in 11 cases. In 14 cases a mass transfusion was necessary. In addition to clinical signs of inflammation, (10 × redness, 12 × wound secretion, 6 × fistula) elevated levels of c-reactive-protein (7.7 mg/dl) and white-blood-cells (10.5/nl) were found. Bacterial cultures harvested during the initial surgical revision demonstrated mixed cultures in 17/18 cases, with an average of 3 different organisms isolated per case (61% intestinal bacteria). During the scheduled repetitive debridement a reduction of the initial mixed cultures into a single organism was observed. Overall 6.8 surgical interventions, including implant removal, were necessary until osteomyelitis was eradicated. In no cases was re-osteosynthesis performed. In 6/18 cases recurrence of infection occurred after an average of 5 months, followed by an additional repetitive debridement. An average 3-year-follow-up after the initial osteomyelitis-diagnosis demonstrated eradication of infection in 17/18 cases combined with an Orlando-Pelvic-Score of 21.9 points (best possible function: 40 points). Despite significant pelvic malalignment the ability to walk was achieved in all patients, with one exception due to a spinal cord injury. Conclusions. Despite no new surgical stabilization of the initial unstable pelvic injury, the early removal of implants combined with extensive debridement and antibiotic therapy led to sufficient long-term outcomes in patients with early posttraumatic pelvic-osteomyelitis. In particular, due to the severity of the initial injury and the complex interdisciplinary approach, early diagnosis of the osteomyelitis is essential

Aims

Bacterial infection activates neutrophils to release neutrophil extracellular traps (NETs) in bacterial biofilms of periprosthetic joint infections (PJIs). The aim of this study was to evaluate the increase in NET activation and release (NETosis) and haemostasis markers in the plasma of patients with PJI, to evaluate whether such plasma induces the activation of neutrophils, to ascertain whether increased NETosis is also mediated by reduced DNaseI activity, to explore novel therapeutic interventions for NETosis in PJI in vitro, and to evaluate the potential diagnostic use of these markers.

Post-traumatic avascular necrosis of the femoral head usually occurs after hip dislocation and femoral neck fracture. Recently along the development of hip arthroscopy, early stage of avascular necrosis of the femoral head can be treated rthroscopically. We hereby present two cases of post-traumatic avascular necrosis patients treated with hip arthroscopy. Case 1. Twenty one year old female patient came to the hospital because of fall from height of 3 floors. Left acetabular fracture, both superior pubic rami fractures and severely displaced left femoral neck fracture were identified at the emergency department (Fig. 1-A). She underwent surgery at the injury day. After the repair of ruptured urinary bladder, internal fixation of the femoral neck was done. Four cannulated screws with washers were inserted for displaced femoral neck fracture, consistent with garden stage IV (Fig. 1-B). Skeletal traction of ipsilateral lower extremity was applied four weeks after the surgery for acetabular fracture. She visited us for painful limitation of motion on left hip at eight months postoperatively. Plain radiograph showed collapse of femoral head and osteophyte formation which were caused by post-traumatic avascular necrosis (Fig. 1-C,D). Femoral head was perforated by a screw. She was planned to remove the screw and resect the osteophyte arthroscopically. On arthroscopic examination, severe synovitis and folded, collapsed femoral cartilage were identified (Fig. 1-E). Screws were removed and osteophyte were also resected (Fig. 1-F). We filled the cavity caused by the screws with allogenic strut graft for structural support. After the surgery, pain was relieved and she came back to her active daily living and for six months, no other complication nor further collapse were identified postoperatively. Case 2. Fourty year old male patient was admitted to the hospital for fall from height about fifteen feet from the ground. Left femoral neck fracture was identified on the emergency department. Previously he had underwent intramedullary nailing for the femoral shaft fracture about five years ago. Urgent internal fixation with four cannulated screws was done on the day of injury. The fixation was unsatisfactory because previously inserted intramedullary nail hindered the proper trajectory of screws. Furthermore, direction of cephalad interlocking holes of the nail were not consistent with the anteversion of femoral neck, we could not place the screws through the nail. Four months after the index surgery, collapse of femoral head and loosening of screws have occurred. MRI showed the collapse of femoral head and posttraumatic avascular necrosis. Prominent bony beak of femoral neck were identified and he complained difficulty and pain on his hip during abduction. We left two screws for secure fixation and resected the bony beak using arthroscopic burr. After the surgery, he felt free from the pain on abduction of hip. Discussion. Even though collapse of the femoral head is identified, early intervention by the arthroscopy could minimize pain or delay the progression of arthritic change. Authors think that it might be helpful for the young adult patients in terms of pain relief and potential delay of the total hip arthroplasty

Aim/Purpose. Review our unique experience in the management of 29 consecutive casualties who survived open pelvic fractures following a blast mechanism. Methods and Results. Retrospective study utilising a prospectively collected combat trauma registry. Records of UK Service Personnel sustaining open pelvic fractures from an explosion from Aug 2008 – Aug 2010 identified. Casualties who survived to be repatriated to the Royal Centre for Defence Medicine, University Hospital Birmingham were selected for further study. The median New Injury Severity Score (NISS) was 41. Mean blood requirement in the first 24 hours was 60.3 units. In addition to their orthopaedic injury, 6 (21%) had an associated vascular injury, 7(24%) had a bowel injury, 11 (38%) had a genital injury and 7(24%) had a bladder injury. 8 (28%) fractures were managed definitively with external fixation, and 7 (24%) fractures required internal fixation. Of those patients who underwent internal fixation, 5 (57%) required removal of metalwork for infection. Faecal diversion was performed on 9 (31%) casualties. Median length of stay was 70.5 days, and mean total operative time was 29.6 hours. At a mean 20.3 months follow-up, 24 (83%) were able to ambulate, and 26 (90%) had clinical and radiological evidence of pelvic ring stability. Conclusion. As a result of the “Global War on Terror” injuries that were previously confined exclusively to conflict areas can now occur anywhere in the form of terrorist attacks. Given the nature of the soft tissue injury, we would advocate an approach of predominantly external fixation in the management of these fractures. With the advent of emerging wound and faecal management techniques, we do not believe that faecal diversion is mandated in all cases

The aim of this study is to review our unique experience in the management of 29 consecutive casualties who survived open pelvic fractures following a blast mechanism, in order to determine the injury pattern, clinical management and outcome of these devastating injuries. All patients were serving soldiers who were injured whilst on operations in Afghanistan. The median New Injury Severity Score (NISS) was 41. Mean blood requirement in the 1. st. 24 hours was 60.3 units. In addition to their orthopaedic injury, 6 (21%) had an associated vascular injury, 7(24%) had a bowel injury, 11 (38%) had a genital injury and 7(24%) had a bladder injury. 8 (28%) fractures were managed definitively with external fixation, and 7 (24%) fractures required ORIF. Of those patients who underwent ORIF, 4 (57%) required removal of metalwork for infection. Faecal diversion was performed on 9 (31%) casualties. Median length of stay was 70.2 days, and mean total operative time was 29.6 hours. At a mean 20.3 months follow-up, 24 (83%) were able to ambulate, and 26 (90%) had clinical and radiological evidence of pelvic ring stability. The “Global War on Terror” has resulted in incidents that were previously confined exclusively to conflict areas can now occur anywhere, and surgeons who are involved in trauma care may be required to manage similar injuries from terrorist attacks. Our study clearly demonstrates that the management of this injury pattern is extremely resource intensive with the need for significant multi-disciplinary input. Given the nature of the soft tissue injury, we would advocate an approach of minimal internal fixation in the management of these fractures. With the advent of emerging wound and faecal management techniques, we do not believe that faecal diversion is mandated in all cases

Background. The relationship between obesity and cauda equina syndrome (CES) has not been previously evaluated or defined. Aim. Purpose of this study was to examine the presentation, timing of surgery, peri-operative complications and outcome of Cauda Equina Syndrome in relation to Body Mass Index. Methods. A single centre retrospective analysis was performed on 40 patients admitted with cauda equina syndrome. Data was collected regarding patient demographics, body mass index (BMI), co-morbidities, onset & mode of presentation and speed of functional recovery following surgery. Results. There were 18 males and 22 females with an overall average age of 38.9 years. The average height was 168.7 cm, and the average weight was 89.3 kg, giving an average BMI of 30.6 Kg/m2. 80% of patients were considered overweight (BMI 25–29.5) or obese (BMI >30). The average duration of back or leg pain prior to presentation was 4.2 years for the obese group and 1.3 years for the non-obese group. Bilateral sciatica, urinary incontinence and dense peri-anal numbness were the predominant presenting features in the obese group. Onset of symptoms was slow and gradually evolving in the obese group compared to the fast onset in the obese group. In the non-obese group, 71% underwent surgery within 24 hrs as opposed to 31% in the obese group. Average follow-up was 6months (6 weeks to 14 months). We observed that higher the BMI more slower the recovery with residual neurology and sphincter dysfunction. Patients in ideal group had prompt early symptomatic recovery with no residual neurology and full bladder recovery. There was correlation between increasing BMI and increased rate of surgical complications. Conclusion. This is the first study exploring the impact of body mass index on CES presentation and outcome. Specific care in establishing an early diagnosis in obese individuals is imperative for timely intervention

Background. Arthroplasty requires an interdisciplinary multimodal approach with anaesthetists playing a key role; providing stable intra-operative conditions, allowing rapid patient recovery, optimising analgeisa and minimizing side-effects. The incidence of post-operative urinary retention (POUR) varies significantly in joint arthroplasty (10–84%). Current literature quotes lower doses of opioids have been shown to reduce POUR, however studies consistently show spinal opioids influence bladder function causing urinary retention. Existing literature fails to comment upon the rate of POUR following joint arthroplasty comparing intrathecal diamorphine against intrathecal local anaesthetic (ITLA) within a modern fast track arthroplasty system (FTA). Methods. A two-year (2009–11) retrospective analysis was conducted encompassing a multi-surgeon duel-centre review. Rates of POUR were compared when utilising ITLA and multimodal analgesia including local anaesthetic infiltration (LIA) (site A) against ITLA in combination with intrathecal diamorphine (site B) for joint arthroplasty under spinal analgesia. Outcomes were analysed using 30-day POUR rates coding data and cross-referenced against patient records. Information was collected on patient co-morbidity, age, gender, surgery duration and renal function. Patients were excluded for previous POUR, prostate pathology, postoperative PCA, and conversion to general anaesthetic. Results. 2343 patients underwent joint arthroplasty within this period. At Site A 12 episodes of POUR were identified, whilst 71 were identified at site B. After exclusions, 56 cases underwent analysis. All had a clinical and radiological diagnosis of POUR. The study participants' mean age was 71 years, BMI 27.9 (range 20–47) and 96% were male. Patients across both sites had comparable co-morbidities. All patients at site B had intrathecal morphine with 96% having 3 micrograms of diamorphine. 30-day POUR rates at Site A (ITLA and LAI) were 1.2% and Site B (ITLA and intrathecal morphine) 5.4% (p=0.0001). Conclusion. The absence of intrathecal diamorphine in spinal anaesthesia significantly reduces the rates of POUR in patients undergoing joint arthroplasty

The femur is a common site for skeletal metastases. The Gamma2 nail has proved effective in relieving pain and restoring function. Little data exists on the use of the Gamma3 Long Nail (GLN) in this condition. Improved instrumentation is suggested to reduce operative time and facilitate minimally invasive surgery. This study reports a series of patients treated in a District General Hospital. A retrospective casenote review was performed of all patients treated with the GLN for femoral metastatic disease over a five year period. Patients were followed-up for a minimum of one year. Functional level was assessed using the Parker Mobility Score (PMS). 12 patients underwent 15 nailings. Mean age was 75.4 years (median 75.7, range 61-92). In bilateral cases, the operations were performed during the same hospital admission. There were seven prophylactic nailings for impending fracture from proximal femoral lesions, seven procedures for actual fractures distal to the intertrochanteric line, and one basicervical fracture associated with multiple femoral metastases. Primaries were four prostate, two breast, two lung, one bowel, one bladder, one renal, and one myeloma. Average anaesthetic time for all procedures was 134 mins (median 125, range 90-210). Average peri-operative drop in serum haemoglobin was 2.3g/dL (median 2.1, range 0.6-4.8). Five patients with actual fracture and one patient with impending fracture required blood transfusion, receiving 2.2 units on average. In-hospital mortality rate was 0.83%, with only one patient not surviving to discharge. One year mortality was 83.3%. Only two patients were alive one year post-operation. Of the remaining patients, average survival was 3.2 months (median 3, range 1-6). Patients spent an average of 17 days on an acute orthopaedic unit (median 14, range 4-80). Two patients required further convalescence in a rehabilitation unit. There were three surgical complications. Two impending fractures became complete, One intra-operatively and one post-operatively. In the case of basi-cervical fracture, the proximal screw cut out of the femoral head, requiring revision to a long-stem bipolar hemiarthroplasty. This was the only re-operation required in this series. Average pre-operative PMS was 5.2 (median 4, range 2-9). Average peri-operative drop in PMS was two points (median 1.5, range 0-6). Of the 11 patients who survived to discharge, 10 were independently mobile and returned to their pre-operation residence. Nine required a change in walking aids. Only one patient reported post-operative pain. This small patient series suggests that the Gamma3 Long Nail is a suitable treatment option for impending and actual metastatic femoral fractures in the District General setting. Length of stay, in-hospital mortality and re-operation rates compare favourably with published data on the Gamma2. There was a significant drop in Parker Mobility Score but all patients bar one were independently mobile and returned to their home. Anaesthetic time was not lower than with the Gamma2, suggesting little tangible benefit of the new instrumentation

Virtual encounters have experienced an exponential rise amid the current COVID-19 crisis. This abrupt change, seen in response to unprecedented medical and environmental challenges, has been forced upon the orthopaedic community. However, such changes to adopting virtual care and technology were already in the evolution forecast, albeit in an unpredictable timetable impeded by regulatory and financial barriers. This adoption is not meant to replace, but rather augment established, traditional models of care while ensuring patient/provider safety, especially during the pandemic. While our department, like those of other institutions, has performed virtual care for several years, it represented a small fraction of daily care. The pandemic required an accelerated and comprehensive approach to the new reality. Contemporary literature has already shown equivalent safety and patient satisfaction, as well as superior efficiency and reduced expenses with musculoskeletal virtual care (MSKVC) versus traditional models. Nevertheless, current literature detailing operational models of MSKVC is scarce. The current review describes our pre-pandemic MSKVC model and the shift to a MSKVC pandemic workflow that enumerates the conceptual workflow organization (patient triage, from timely care provision based on symptom acuity/severity to a continuum that includes future follow-up). Furthermore, specific setup requirements (both resource/personnel requirements such as hardware, software, and network connectivity requirements, and patient/provider characteristics respectively), and professional expectations are outlined. MSKVC has already become a pivotal element of musculoskeletal care, due to COVID-19, and these changes are confidently here to stay. Readiness to adapt and evolve will be required of individual musculoskeletal clinical teams as well as organizations, as established paradigms evolve.
