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. 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.Aims

The aim of this study was to identify the effect of COVID-19 lockdown on the rates, types, mechanisms and mortality of musculoskeletal trauma across Scotland. Data for all musculoskeletal trauma requiring operative treatment was collected prospectively from five orthopaedic units across Scotland during the initial lockdown period (23/03/2020-28/05/2020). This was compared with data for the same timeframe in 2018 and 2019. Data collected included all cases requiring surgery, injury type, mechanism of injury, and inpatient mortality. 1315 patients received operative treatment in 2020 compared to 1791 in 2019 and 1719 in 2018. The numbers of all injury types decreased, but the relative frequency of hip fractures increased(36.3% 2020 vs 30.2% 2019, p<0.0001 & 30.7% 2018, p<0.0001). Significant increases were seen in proportion of DIY-related injuries(3.1% 2020 vs 1.7% 2019, p=0.01 & 1.6% 2018, p<0.01) and injuries caused by falls(65.6% 2020 vs 62.6% 2019, p=0.08 & 61.9% 2018, p=0.05). Significant decreases were seen in proportion of RTCs(2.6% 2020 vs 5.4% 2019, p<0.0001 & 4.2% 2018, p=0.02) and occupational injuries(1.8% 2020 vs 3.0% 2019, p=0.03 & 2.3% 2018, p=0.01). A significant increase in proportion of self-harm injuries was seen(1.7% 2020 vs 1.1% 2019, p=0.19 & 0.5% 2018, p<0.0001). Mortality of trauma patients was significantly higher in 2020 (4.9%), than in 2019 (3.2%, p=0.02) and 2018 (2.6%, p<0.0001). In conclusion, lockdown has resulted in a marked reduction of musculoskeletal trauma requiring surgery in Scotland. There have been major changes in types and mechanisms of injury, and mortality of trauma patients has risen significantly.
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. 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.Aims
