ABSTRACT

Here we present a novel adaptation of the previously described fibula pro-tibial fixation in a case requiring salvage fixation of a bimalleolar ankle fracture in an osteoporotic patient. Unstable osteoporotic ankle fractures are a challenging injury to manage and typically occur in a frail and comorbid subgroup of patients. Various techniques have been described in the evolution of managing these injuries, e.g. hindfoot nailing and anatomical locking plates, however in this uniquely challenging case a novel strategy was required to mitigate bone loss in the distal fibular fracture fragment. There is some evidence to suggest fibular protibial fixation offers a lower complication profile to its alternatives. The novel use of distal fibula pro-tibial screws offers a new alternative to hindfoot nailing of bimalleolar ankle fracture in osteoporotic bone with compromised distal fibular fragment bone purchase. Further research is required to investigate the compatibility of this technique with early weightbearing.

ABSTRACT

INTRODUCTION: The aim of this study was to evaluate noise exposure to the operating room staff consisting of the surgeon, assistant, anaesthetist and Mako Product Specialist (MPS) during Mako robotic-arm assisted total knee arthroplasty (TKA) and total hip arthroplasty (THA). We aimed to determine whether employees were exposed to noise at or above a lower exposure action value (LEAV) set out by the Noise at Work Regulations 2005, Health and Safety Executive (HSE), UK. MATERIALS AND METHODS: We prospectively recorded intra-operative noise levels in Mako robotic-arm assisted TKA and THA over a period of two months using the MicW i436 connected to an iOS device (Apple), using the Sound Level Meter App (iOS) by the National Institute for Occupation Safety and Health (NIOSH). Data obtained was then used to calculate "worst case" daily exposure value to assess if sound levels were compliant with UK guidelines. Comparison between operating room staff groups was performed with ANOVA testing. RESULTS: A total of 19 TKA and 11 THA operations were recorded. During TKA, for the primary surgeon and the assistant, the equivalent continuous sound pressure level (LAeq) was over 80 dB, exceeding the LEAV set out by the Noise at Work Regulations by HSE. During THA, the average LAeq and peak sound pressure levels did not exceed the LEAV. The calculated daily exposure for the primary surgeon in TKA was 82 dB. A Tukey post hoc test revealed that LAeq was statistically significantly lower in the anaesthetist and MPS (p < .001) compared to the primary surgeon and assistant in both TKA and THA. CONCLUSIONS: Operating room staff, particularly the primary surgeon and assistant are exposed to significant levels of noise during Mako robotic-arm assisted TKA and THA. Formal assessments should be performed to further assess the risk of noise induced hearing loss in robotic-arm assisted arthroplasty.

ABSTRACT

Background: This study aimed to assess the outcomes of patients with complex rib fractures undergoing operative or nonoperative management at our major trauma center. Methods: A retrospective review of all patients who were considered for surgical stabilization of rib fractures (SSRF) at a single major trauma center from May 2016 to September 2022 was performed. Results: In total, 352 patients with complex rib fractures were identified. Thirty-seven patients (11%) fulfilled the criteria for surgical management and underwent SSRF. The SSRF group had a significantly higher proportion of patients with flail chest (32 [86%] vs. 94 [27%], p<0.001) or Injury Severity Score (ISS) >15 (37 [100%] vs. 129 [41%], p<0.001). No significant differences were seen between groups for 1-year mortality. Patients who underwent SSRF within 72 hours were 6 times less likely to develop pneumonia than those in whom SSRF was delayed for over 72 hours (2 [18%] vs. 15 [58%]; odds ratio, 0.163; 95% confidence interval, 0.029-0.909; p=0.036). Prompt SSRF showed non-significant associations with shorter intensive care unit length of stay (6 days vs. 10 days, p=0.140) and duration of mechanical ventilation (5 days vs. 8 days, p=0.177). SSRF was associated with a longer hospital length of stay compared to nonoperative patients with flail chest and/or ISS >15 (19 days vs. 13 days, p=0.012), whilst SSRF within 72 hours was not. Conclusion: Surgical fixation of complex rib fractures improves outcomes in selected patient groups. Delayed surgical fixation was associated with increased rates of pneumonia and a longer hospital length of stay.

ABSTRACT

Introduction: There is increasing evidence that the prescription opioid crisis is spreading internationally. However, there is scarce literature comparing contemporary prescribing practices between units in different countries, particularly in the context of this evolving international problem. We sought to determine the patterns of postoperative opioid prescribing in three hospitals from geographically distinct regions. Methods: This is a retrospective cohort study involving patients from three hospitals: XXX, Maine, USA; XXX, Scotland; and XXX, Australia. The health records, surgical details, and frequency and potency of discharge prescriptions were analyzed for 350 patients receiving surgery for isolated wrist or ankle fractures. Regression analysis was used to identify independent predictors of prescription opioid provision. Results: Following ankle fracture surgery, Aberdeen patients (OR 6.0, 95% CI 3.0-11.5) and Adelaide patients (11.8, 95% CI 4.1-39.6) were significantly more likely to receive a prescription for opioids than those in Augusta (p < 0.001). For distal radius fractures, this was also the case (Aberdeen OR 21.2, 95% CI 7.2-79.3, Adelaide OR 21.6, 95% CI 7.3-81.3). For both fracture groups, the potency of prescription provided (measured in morphine milligram equivalents) was not significantly different. When opioids were included in the discharge prescription, Adelaide prescribers favored strong opioids, Aberdeen prescribers selected weak opioids, and prescribers in Augusta chose an even distribution of both types (p < 0.001). Multivariate analysis demonstrated that the odds of receiving prescription opioids were significantly influenced by geographic location and decreased by advancing patient age. Conclusions: Geographic location is a key factor influencing the provision of postoperative opioids. We found no association with fracture type, patient demographic factors or intra-operative practices. Prescriber culture is likely an influential determinant of postoperative opioid provision. Emphasis on patient and prescriber education regarding the risks of prescription opioids and their potential long-term sequelae is key if we wish to change modifiable prescriber behavior.

ABSTRACT

The American 'opioid crisis' is rapidly spreading internationally. Perioperative opioid use increases the risk of long-term opioid use. We review opioid use following wrist and ankle fracture fixation across Scotland, establishing prescribing patterns and associations with patient, injury, or perioperative factors. Six Scottish orthopedic units contributed. A total of 598 patients were included. Patient demographics were similar across all sites. There was variation in anesthetic practice, length of stay, and AO fracture type (p < 0.01). For wrist fractures, 85.6% of patients received a discharge opioid prescription; 5.0% contained a strong opioid. There was no significant variation across the six units in prescribing practice. For ankle fractures, 82.7% of patients received a discharge opioid prescription; 17% contained a strong opioid. Dundee and Edinburgh used more strong opioids; Inverness and Paisley gave the least opioids overall (p < 0.01). Younger patient age, location, and length of stay were independent predictors of increased prescription on binary regression. Despite variability in perioperative practices, discharge opioid analgesic prescription remains overwhelmingly consistent. We believe that the biggest influence lies with the prescriber-institutional 'standard practice'. Education of these prescribing clinicians regarding the risk profile of opioids is key to reducing their use following surgery, thus lowering long-term opioid dependence.

ABSTRACT

PURPOSE: Recent research has outlined the increasing incidence of acute kidney injury (AKI) and its effect on morbidity/mortality. There is evidence that current rates are significantly under-reported nationally, with uncertainty about pre-operative factors that might influence AKI reduction and the impact on other healthcare outcomes such as mortality and later Chronic Kidney Disease (CKD) development. We set out to help address these current deficiencies in the literature. METHODS: A retrospective cohort study was undertaken using data collected from patients undergoing elective primary lower limb arthroplasty within our institution from 01/10/16-31/09/17 with a 2-year follow-up. RESULTS: 53/782 (6.8%) patients had an AKI during the study time period. This was associated with a longer inpatient stay (p < 0.001). There was no significant difference in 30-day mortality (p = 0.134), 30-day readmission (p = 1.00) or later CKD development (p = 0.63). Independent predictors of AKI were as follows: Diabetes (OR 2.49; 95%CI 1.15-5.38; p = 0.021), CKD (OR 4.59; 95%CI 2.37-8.92; p < 0.001) and Male sex (OR 2.61; 95%CI 1.42-4.78; p = 0.002). CONCLUSIONS: AKI in those undergoing hip and knee arthroplasty remains under-reported at a national level. AKI development was associated with an increased length of stay, but not long-term healthcare outcomes. This may be due to the mechanism of AKI development or the low absolute numbers of AKI suffered. We have identified three pre-operative factors (Diabetes, CKD & Male Sex) that were independently predictive of AKI. Targeted interventions may reduce the risk of AKI after lower limb arthroplasty.

ABSTRACT

INTRODUCTION: The COVID-19 lockdown resulted in decreased vehicle use and an increased uptake in cycling. This study investigated the trends in cycling-related injuries requiring orthopaedic intervention during the COVID-19 lockdown period compared with similar time periods in 2018 and 2019. METHODS: Data were collected prospectively for patients in 2020 and collected retrospectively for 2019 and 2018, from hospitals within four NHS Scotland Health Boards encompassing three major trauma centres. All patients who sustained an injury as a result of cycling requiring orthopaedic intervention were included. Patient age, sex, mechanism of injury, diagnosis and treatment outcome from electronic patient records. RESULTS: Number of injuries requiring surgery 2020: 77 (mean age/years - 42.7); 2019: 47 (mean age/years - 42.7); 2018: 32 (mean age/years - 31.3). Overall incidence of cycling injuries 2020: 6.7%; 2019: 3.0%; 2018: 2.1%. Commonest mechanism of injury: fall from bike 2020 n = 54 (70.1%); 2019 n = 41 (65.1%); 2018 n = 25 (67.6%). Commonest injury type: fracture 2020 n = 68 (79.1%); 2019 n = 33 (70.2%); 2018 n = 20 (62.5%). Commonest areas affected: Upper extremity: 2020 n = 45 (58.5%); 2019 n = 25 (53.2%); 2018 n = 25 (78.1%). Lower extremity: 2020 n = 23 (29.9%); 2019 n = 14 (29.7%); 2018 n = 7 (21.8%). CONCLUSION: A significant increase in the number of cycling related injuries requiring orthopaedic intervention, a greater proportion of female cyclists and an older mean age of patients affected was observed during the COVID-19 lockdown period compared with previous years. The most common types of injury were fractures followed by lacerations and fracture-dislocations. The upper extremity was the commonest area affected.

ABSTRACT

We present the case of a 56-year-old man who sustained a tibial tuberosity fracture with an associated patellar fracture. In the adult population there are only a few documented cases of tibial tuberosity fractures. This is only the second recorded case of bifocal patella tendon avulsion. The patient was managed successfully by fixation of the tibial tuberosity alone as the patella fracture was undisplaced and the patella retinaculum intact. A key point was screening the patella fracture at time of fixation to aid this decision. We achieved a good outcome at one year with internal fixation and early mobilisation.

ABSTRACT

AIMS: The UK government declared a national lockdown on 23 March 2020 to reduce transmission of COVID-19. This study aims to identify the effect of lockdown on the rates, types, mechanisms, and mortality of musculoskeletal trauma across Scotland. METHODS: Data for all musculoskeletal trauma requiring operative treatment were collected prospectively from five key orthopaedic units across Scotland during lockdown (23 March 2020 to 28 May 2020). This was compared with data for the same timeframe in 2019 and 2018. Data collected included all cases requiring surgery, injury type, mechanism of injury, and inpatient mortality. RESULTS: A total of 1,315 patients received operative treatment from 23 March 2020 to 28 May 2020 compared with 1,791 in 2019 and 1,719 in 2018. The numbers of all injury types decreased, but the relative frequency of hip fractures increased (36.3% in 2020 vs 30.2% in 2019, p < 0.0001 and 30.7% in 2018, p < 0.0001). Significant increases were seen in the proportion of DIY-related injuries (3.1% in 2020 vs 1.7% in 2019, p = 0.012 and 1.6% in 2018, p < 0.005) and injuries caused by falls (65.6% in 2020 vs 62.6% in 2019, p = 0.082 and 61.9% in 2018, p = 0.047). Significant decreases were seen in the proportion of road traffic collisions (2.6% in 2020 vs 5.4% in 2019, p < 0.0001 and 4.2% in 2018, p = 0.016), occupational injuries (1.8% in 2020 vs 3.0% in 2019, p = 0.025 and 2.3% in 2018, p = 0.012) and infections (6.8% in 2020 vs 7.8% in 2019, p = 0.268 and 10.3% in 2018, p < 0.012). Cycling injuries increased (78 in 2020 vs 64 in 2019 vs 42 in 2018). A significant increase in the proportion of self-harm injuries was seen (1.7% in 2020 vs 1.1% in 2019, p = 0.185 and 0.5% in 2018, p < 0.0001). Mortality of trauma patients was significantly higher in 2020 (5.0%) than in 2019 (2.8%, p = 0.002) and 2018 (1.8%, p < 0.0001). CONCLUSION: The UK COVID-19 lockdown has resulted in a marked reduction in musculoskeletal trauma patients undergoing surgery in Scotland. There have been significant changes in types and mechanisms of injury and, concerningly, mortality of trauma patients has risen significantly.Cite this article: Bone Joint Open 2020;1-9:541-548.

ABSTRACT

AIM: Patients with hip fractures are often frail with multiple comorbidities and at risk of medical serious adverse events (SAEs). We investigated the HEALTH trial patient population to ascertain predictors of SAEs. METHODS: We performed a multivariable Cox regression analysis. Occurrence of SAEs was included as the dependent variable with 31 potential prognostic factors being included as independent variables. RESULTS: One thousand four hundred forty-one patients were included in this analysis. Three hundred seventy (25.6%) patients suffered from an SAE. The most common events were cardiac (38.4%, n = 105), respiratory (20.8%, n = 77), and neurological (14.1%, n = 77). The majority of SAEs (50.8%, n = 188) occurred in the first 90 days after hip fracture with 35.4% occurring in the first 30 days (n = 131). Body mass index (BMI) between 18.5 and 24.9 compared with BMI between 25 and 29.9 [hazard ratio (HR) 1.32, P = 0.03] and receiving a total hip arthroplasty compared with a bipolar hemiarthroplasty (HR 1.36, P = 0.03) were associated with a higher risk of a medical SAE within 24 months of femoral neck fracture. Age (P = 0.09), use of femoral cement (P = 0.59), and use of canal pressurization (P = 0.37) were not associated with a medical SAE. CONCLUSION: Total hip arthroplasty is associated with more SAEs in the immediate postoperative period, and care should be taken in selecting patients for this treatment compared with a hemiarthroplasty. A higher BMI may be protective in hip fracture patients while age alone does not predict SAEs and neither does the use of femoral cement and/or pressurization. LEVEL OF EVIDENCE: Prognostic Level II. See Instructions for Authors for a complete description of levels of evidence.

ABSTRACT

BACKGROUND: The primary objective of this study was to determine the incidence of symptomatic venous thromboembolism (VTE), including pulmonary embolism (PE) and deep vein thrombosis (DVT), in the hip fracture population. Secondary objectives included determining timing of VTE diagnosis, VTE thromboprophylaxis given, and identifying any factors associated with VTE. METHODS: Using data from the FAITH and HEALTH trials, the incidence of VTE, including DVT and PE, and the timing of VTE were determined. A multivariable Cox regression analysis was used to determine which factors were associated with increased risk of VTE, including age, treatment for comorbidity, thromboprophylaxis, time to surgery, and method of fracture management. RESULTS: 2520 hip fracture patients were included in the analysis. Sixty-four patients (2.5%) had a VTE [DVT: 36 (1.4%), PE: 28 (1.1%)]. Thirty-five (54.7%) were diagnosed less than 6 weeks postfracture and 29 (45.3%) more than 6 weeks postfracture. One thousand nine hundred ninety-three (79%) patients received thromboprophylaxis preoperatively and 2502 (99%) received thromboprophylaxis postoperatively. The most common method of preoperative (46%) and postoperative (73%) thromboprophylaxis was low molecular weight heparin. Treatment with arthroplasty compared to internal fixation was the only variable associated with increased risk of VTE (hazard ratio 2.67, P = 0.02). CONCLUSIONS: The incidence of symptomatic VTE in hip fracture patients recruited to the 2 trials was 2.5%. Although over half of the cases were diagnosed within 6 weeks of fracture, VTE is still prevalent after this period. The majority of patients received thromboprophylaxis. Treatment with arthroplasty rather than fixation was associated with increased incidence of VTE. LEVEL OF EVIDENCE: Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

ABSTRACT

PURPOSE: Distal femoral fractures in the elderly are associated with high morbidity and mortality and their incidence is increasing with an ageing population. Management of these fractures has evolved over recent decades and there is now an accepted recognition of the important role that acute arthroplasty may have in treatment of these fractures. Our purpose was to systematically review the evidence available in the literature for arthroplasty as a treatment option for distal femoral fractures. METHODS: This systematic review was conducted in accordance with the PRISMA reporting guidelines. We searched CENTRAL, MEDLINE, EMBASE, and Science Citation Index Expanded (until October 2018) for studies and case series. Furthermore, clinical trial registries were searched for ongoing studies. We included all studies or case series that described total knee arthroplasty for distal femoral fractures irrespective of language, publication status, sample size, or follow-up period due to limited studies available in the literature. Exclusion criteria included single patient case reports, isolated tibia fractures, and periprosthetic fractures. Two authors independently identified trials for inclusion and independently extracted the data. Outcome measures included mortality, peri-operative complications (excluding mortality), anaesthetic time, blood loss, time to mobilisation, length of hospital stay, functional scores, radiological loosening, and revision rate. RESULTS: Fourteen papers were included for subsequent quantitative and qualitative synthesis incorporating a total of 181 patients. The highest level of evidence identified was a single cohort study (level III), the remaining 13 papers consisted of multi- or single-centre case series (level IV). The mean mortality rate was 3.34% (range 0-10) at 30 days and 18.4% (range 0-42) at 1 year. The mean revision rate was 3.43% (range 0-25) at 1 year. The mean time to mobilisation was 3.90 days (range 2.5-6) with a mean time to discharge from the acute ward being 16.6 days (range 8-33). CONCLUSIONS: Although there is limited evidence in the literature available, our review suggests that there is a role for acute knee arthroplasty in distal femoral fractures. This mode of treatment has satisfactory mortality and revision rates, and may result in faster time to mobilisation and discharge. There is a need for a higher level of evidence to delineate this issue further.

ABSTRACT

There is an enormous burden of disease associated with the management of a failed hip fracture fixation. The goal of surgical management is to facilitate an early return to mobilization with the retention of as much independence as possible. Despite numerous studies that are focused on the care of patients with proximal femur fractures, complication rates remain high. Surgeons should review current strategies to avoid and manage complications after hip fracture fixation. This will have important implications given the detrimental consequences of failed management of hip fractures, including permanent disability, life-threatening medical complications, and an increased risk of death.

ABSTRACT

The majority of femoral fractures are surgically treated with intramedullary nails. Non-union rate is low but challenging and costly if it occurs. There have been encouraging results from the use of augmentative plating as a treatment for non-union of femoral fractures. We performed a systematic review of the literature to compare union rates, time to union and complications between exchange nailing and augmentative plating as a primary procedure following a diagnosis of femoral non-union following initial nailing. We found a total of 21 papers, which found the mean union rate of augmentative plating to be 99.8% compared to 74% (P = 2.05-12) found for exchange nailing. Times to union were comparable at 5.9 months for augmentative plating and 6.3 months for exchange nailing (P = 0.68916), and complication rate was 4% for augmentative plating compared to 20% for exchange nailing. From the evidence available, plate augmentation provides a more reliable union rate if used as the first operative intervention on a non-union of a femoral fracture compared to exchange nailing.Level of Evidence IV Systematic review of therapeutic studies.

ABSTRACT

The surgical management of tibial plateau fractures can be technically demanding. In younger patients, the mainstay is fixation with cartilage preservation. In older patients with osteoporotic bone, this method has higher rates of fixation failure; in addition, it requires prolonged bed rest or protected weight bearing, which are major challenges in this group. In contrast, total knee arthroplasty performed acutely for primary treatment of tibial plateau fractures has potential advantages for elderly patients, such as immediate stability, early mobilization, and positive functional outcomes with decreased rates of reoperation. Additionally, arthroplasty can be technically challenging in younger patients with previous tibial plateau fractures in whom debilitating posttraumatic arthritis develops. In these patients, old wounds, retained metalwork, bony deficiency, and instability can lead to poorer outcomes and higher complication rates than in routine knee arthroplasty. In both cases, we recommend surgery be performed by experienced arthroplasty surgeons with ample access to a range of implants with varying constraints and the option of stems and augments.

ABSTRACT

Unicondylar knee replacement is a relatively common elective orthopedic procedure but is not often seen in the Emergency Department setting. Familiarity with normal clinical and radiological appearances is difficult to gain. Dislocation of the mobile bearing component "spacer" is a known complication of unicondylar knee replacements, and these patients will initially present to the accident and Emergency Department. In this setting, an accurate and prompt diagnosis is necessary to appropriately manage the patient's condition. There is normally a radiological challenge in identifying dislocated mobile bearings on plain radiographs. These patients may need to have further imaging, such as a computer tomographic scan to identify the dislocated mobile bearing.

ABSTRACT

BACKGROUND: Total hip arthroplasty (THA) is now an increasingly common procedure for people sustaining acetabular fractures. The incidence of acetabular fractures among the elderly population is increasing, and contemporary treatment aims to avoid the risks of prolonged incumbency associated with poor bone stock for fixation or inability to comply with limited weightbearing in this patient group. The concept of acute hip arthroplasty as a treatment for acetabular fracture is, therefore, becoming more topical and relevant. Our systematic review investigates whether THAs for acetabular fractures should be performed acutely, with a short delay, or as a late procedure for posttraumatic osteoarthritis (PTOA) if it develops. MATERIALS AND METHODS: Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines were followed when undertaking this systematic review. Detailed searches were performed on three different databases, using keywords, such as "acetabular fracture," "acetabular trauma," "total hip arthroplasty," "hip arthroplasty," and "hip prosthesis." Studies from 1975 to September 2016 were included in the study. All studies included in the review were independently critically appraised by two of the authors. RESULTS: Forty three studies were included in this review. Only two of them actually compared acute and delayed THAs for acetabular fractures with the rest focusing on one or the other. Results were comparable between acute and late THAs in terms of aseptic loosening, operative time, blood loss, Harris Hip Score, and ability to mobilize postoperatively without aid. Complication rates, however, were much higher in the acute group. CONCLUSION: Evidence based on this topic is scarce and therefore we have to be cautious about drawing a definitive conclusion. The findings of this systematic review do suggest, however, that acute THAs should be considered in elderly patients, where fixation is not possible, or when their health and ability to rehabilitate are poor. It should also be considered in patients where PTOA is very likely, or where there is already some preexisting degenerative osteoarthritis.

ABSTRACT

BACKGROUND: The objective is to assess the ability of volar locking plates to maintain fracture reduction when used to treat dorsally displaced extra- and intra-articular distal radial fractures. METHODS: This prospective study was conducted over an 12-month period. Consenting patients who had sustained a closed, dorsally displaced distal radial fracture, treated by open reduction and internal fixation using a volar distal radial locking plate were included in the study. Radial inclination, volar tilt, and ulnar variance were measured from radiographs taken at least 3 months after surgery and compared with radiographs of the uninjured side. Only two of the eight participating surgeons have a specialist interest in upper limb surgery. RESULTS: Thirty-three patients were included in the study. There were 23 women and 10 men. The mean age was 49.5 years (range, 26-82 years). According to the Orthopaedic Trauma Association (OTA) classification, there were 19 Type A, 1 Type B, and 13 Type C fractures. The average restoration of volar tilt was 1-degree angle of under correction with a range of 7.3-degree angle of under correction to 3.7-degree angle of over correction, when compared with the uninjured side. The mean restoration of radial inclination was 1.9-degree angle of under correction with a range of 10-degree angle of under correction to 8.4-degree angle of over correction. As a group, the mean ulnar variance was 0 mm with a range of 2 mm of relative ulnar shortening to 3.5 mm of ulnar prominence when compared with the uninjured side. CONCLUSION: In the hands of general trauma surgeons, the volar approach combined with the application of a suitable volar locking plate is a good treatment for restoring and maintaining the anatomy of dorsally displaced intra- and extra-articular distal radial fractures.
