This study aims to evaluate the timing of surgery on peri- and post-operative outcomes in patients with hip fracture on DOAC therapy. Methods Single-centre, retrospective, population-based cohort study of patients on DOAC therapy compared to standard care with low-molecular-weight heparin (LMWH) undergoing surgery for hip fracture. Data obtained: patient demographics, fracture classification, American Society of Anaesthesiologists (ASA) classification, time to surgery, procedure performed, type of DOAC, timing of last DOAC dose, use of reversal agents or pro-coagulants and length of stay. Outcomes assessed: pre- and post-operative haemoglobin levels, incidence of blood transfusion, major haemorrhage, venous thromboembolism (VTE) and death within 30 days of surgery. Results A total of 755 patients were included...

The injuries were assessed and treated with closed reduction and stabilised by buddy taping. Early active range of movement was encouraged and a referral to physiotherapy was made. At the final followup, 4 months after the injury, he lacked subtle end of range movement actively, but functionally he was coping well and had made a full return to work.

We present an unusual case of CTS in a 14-year-old girl who developed this following an accidental electrical shock. As far as we are aware, this is the first case report of CTS in a child following electrical injury. This rare complication of electrical injury can easily be disregarded or misdiagnosed as neuropraxia, and this can delay appropriate treatment, as evidenced by this case. We propose that CTS should be considered when instigating initial medical care after an electrical injury, and that a referral to a hand surgeon should not be delayed, as these children need urgent surgical intervention to preserve hand function.

The aim of this study was to create neural network models which can recognise the gait patterns from pre-and post-treatment and the normal ones. Neural network is a method which works on the principle of learning from experience and then uses the obtained knowledge to predict the unknowns. Methods: Twenty-eight patients with cerebral palsy were recruited as subjects whose gait was analysed in pre and post-treatment. A group of twenty-six normal subjects also participated in this study as control group. All subjects' gait was analysed using Vicon Nexus® to obtain the gait parameters and kinetic and kinematic parameters of hip, knee and ankle joints in three planes of both limbs. The gait data was used as input to create neural network models. A total of approximately 300 trials were split into 70% and 30% to train and test the models, respectively. Different models were built using different parameters. The gait modes were categorised as three patterns, i.e., normal, pre-and post-treatments. Results: The results showed that the models using all parameters or using the joint angles and moments could predict the gait patterns with approximately 95% accuracy. Some of the models e.g., the models using joint power and moments, had lower rate in recognition of gait patterns with approximately 70-90% successful ratio. Conclusion: Neural network models can be used in clinical practice to recognise the gait pattern for cerebral palsy patients.

We present an injury with a ballpoint pen that penetrated the soft tissues and the cortex of the proximal third of the tibia.

However, the role of DOACs in preventing VTE following hip fracture surgery in the older adults remains unclear. This study aims to evaluate the efficacy and safety of DOACs in older adults undergoing surgery for hip fracture. Materials and methods: Single-center, retrospective, population-based cohort study of patients receiving either a DOAC or low-molecular-weight heparin (LMWH) for VTE prophylaxis following hip fracture surgery. Data obtained included patient demographics, comorbidities, fracture classification, time to surgery, procedure performed, and length of stay. Main outcomes assessed were incidence of VTE, incidence of major hemorrhage, and death within 30 days of surgery. Results: A total of 321 patients were included. Incidence of VTE was 0% in the DOAC group and 3.4% in the LMWH group (r...
