RESUMO

BACKGROUND: Orthopaedic surgery involves tools which could cause noise-induced hearing loss in theatre staff. Threshold levels for occupational noise exposure have been developed in the U.K., above which action is required to reduce exposure. The aims of our study were to determine whether equivalent continuous sound pressure levels during elective arthroplasty can be measured using readily available materials, and to assess whether noise exposure levels stand within acceptable occupational noise exposure levels. MATERIALS AND METHODS: Sound pressure levels of orthopaedic saws were recorded using the MicW i436 connected to an iPhone 4S and the iOS SoundMeter application, and using a professional sound meter. Equivalent sound pressure levels were recorded for total hip replacement (THR) and total knee replacement (TKR) using the MicW i436 SoundMeter application. Data obtained was then used to calculate a "worst case" daily exposure value to assess if sound levels were compliant with U.K. RESULTS: Sound pressure levels recorded using the MicW i436 and Soundmeter application were accurate compared to professional soundmeter readings. THR showed equivalent sound pressure levels (LAeq) of 77 dBA and TKR showed a LAeq of 80 db. Calculated "worst case" scenarios for daily noise exposure using these values did not meet the lower exposure action values set out by U.K. CONCLUSIONS: It is possible to accurately measure continuous sound pressure levels during elective orthopaedic surgery using readily available materials. Noise exposure values during TKR meet lower exposure action values, and when "worst case" daily exposure levels are calculated this level is still lower than the threshold.

RESUMO

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.

RESUMO

BACKGROUND: No research is available comparing trainee and consultant outcomes for total hip arthroplasty (THA) for hip fracture. The aim of our study is to determine whether trainee-performed and consultant-performed THA produced equivalent radiological outcomes and complication rates for this patient cohort. METHODS: We performed a retrospective cohort study at our institution, with inclusion of patients who underwent a primary THA for hip fracture between March 30, 2017 and February 07, 2019. Relevant perioperative and outcome data were collected through electronic records. Radiological outcomes were assessed by 2 independent reviewers. Follow-up was performed until August 07, 2019. RESULTS: Eighty-seven patients were included in the study. The mean length of follow-up was 13 months (range, 6-29). Forty-three patients underwent consultant-led operations and 44 underwent trainee-performed (ST3-ST8) operations under consultant supervision. There were no significant differences between the 2 groups regarding complication risk (no recorded dislocation, infection requiring reoperation, revision or 30-day mortality in either group). There were also no significant differences between trainees and consultants regarding the radiological outcomes of mean acetabular component inclination (37.2° vs 36.7°, respectively, P = .74); offset difference (+7.1 mm vs +7.2 mm, respectively, P = .91); leg length difference (+6.4 mm vs +5.7 mm, respectively, P = .56); and barrack grade for femoral cement mantle. CONCLUSION: This study suggests that radiological and safety outcomes for trainees performing THA for hip fracture with appropriate supervision are equivalent to consultant surgeons. However, given the low event rate of complications, a larger study is required to determine whether there is any statistically significant difference.

RESUMO

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.

RESUMO

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.

RESUMO

AIMS: Tourniquets have potential adverse effects including postoperative thigh pain, likely caused by their ischaemic and possible compressive effects. The aims of this preliminary study were to determine if it is possible to directly measure intramuscular pH in human subjects over time, and to measure the intramuscular pH changes resulting from tourniquet ischaemia in patients undergoing knee arthroscopy. METHODS: For patients undergoing short knee arthroscopic procedures, a sterile calibrated pH probe was inserted into the anterior fascial compartment of the leg after skin preparation, but before tourniquet inflation. The limb was elevated for three minutes prior to tourniquet inflation to 250 mmHg or 300 mmHg. Intramuscular pH was recorded at one-second intervals throughout the procedure and for 20 minutes following tourniquet deflation. Probe-related adverse events were recorded. RESULTS: A total of 27 patients were recruited to the study. Mean tourniquet time was 21 minutes (10 to 56). Tourniquet pressure was 300 mmHg for 21 patients and 250 mmHg for six patients. Mean muscle pH prior to tourniquet inflation was 6.80. Muscle pH decreased upon tourniquet inflation, with a steeper fall in the first ten minutes than for the rest of the procedure. Change in muscle pH was significant after five minutes of tourniquet ischaemia (p < 0.001). Mean muscle pH prior to tourniquet release was 6.58 and recovered to 6.75 within 20 minutes following release. No probe related adverse events were recorded. CONCLUSION: It is possible to directly measure skeletal muscle pH in human subjects over time. Tourniquet ischaemia results in a decrease in human skeletal muscle pH over time during short procedures. Cite this article: Bone Joint Res 2021;10(6):363-369.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Bilateral fractured necks of femur are rare, particularly in the absence of high energy trauma or metabolic bone disease. We describe a case of an 89 year old man with no history of metabolic bone disease who presented with bilateral neck of femur fractures following a simple fall. Clinicians must be vigilant to ensure that bilateral neck of femur fractures are identified and treated appropriately.

RESUMO

Acute Achilles tendon rupture is frequently treated conservatively using functional rehabilitation protocols in which the ankle is held in equinus. Equinus is achieved using a variety of means including equinus casts and rigid boots with heel wedges. Concerns have been raised that rigid boots with heel wedges do not achieve adequate equinus. Patients presenting to our institutions with an acute Achilles tendon rupture were randomised to treatment with an equinus cast or rigid boot with heel wedges. After application of these lateral radiographs of the hindfoot and ankle were taken, and these used to measure tibiotalar angle (TTA), tibio-1st metatarsal angle (TMA) and posterior malleolar to calcaneal tip height (PCH). 15 patients were randomised to a rigid boot and 14 to an equinus cast. The mean TTA was 124° in the rigid boot group and 136° in the equinus cast group (p<0.001). The mean TMA was 134° in the rigid boot group and 147° in the equinus cast group (p<0.001). The mean PCH was 25mm in the rigid boot group and 15mm in the equinus cast group (p<0.05). Our results demonstrate that the rigid boots with heel wedges used in our institutions produce significantly less equinus than an equinus cast. Whilst the clinical relevance of this remains uncertain, clinicians should be aware that rigid boots with wedges and equinus casts may not achieve the same degree of Achilles tendon shortening.

RESUMO

INTRODUCTION: Intra-operative assessment of total knee arthroplasty (TKA) components is performed with manufacturer specific jigs. Pre-operative templating, patient specific knee cutting blocks and computer-assisted surgeries have also been used to improve alignment and sizing; although the literature shows marginal improvement in functional scores. We propose pre-operative shoe size as a simple measurement tool for estimating the component sizes required for TKA. We investigate the relationship between TKA implant sizes, height, body weight and shoe size. METHODS: Retrospective single centre cohort study of all patients undergoing primary knee arthroplasty over a four-month period (August-November 2015) was conducted. Standard data items recorded during routine admission. The spearman's rank correlation was used to assess the relationship between variables. RESULTS: One hundred and six patients were included in the final analysis. The mean age of the study group was 67.3 ±â€¯10.1 years (Range 44-90.) There were 42 male patients and 64 female patients. Statistically significant correlations were observed between: Shoe size and femoral component (rho = 0.589, p < 0.05); shoe size and tibial component (rho = 0.718, p < 0.05); shoe size and height (rho = 0.692, p < 0.05); height and femoral component (rho = 0.626, p < 0.05); height and tibial component (rho = 0.674, p < 0.05). CONCLUSION: We have demonstrated positive correlation between shoe and TKR component sizes. This relationship allows surgeons to estimate prosthesis size in the pre-operative setting.
