Aim To compare the accuracy of shoulder ultrasound (US) in diagnosing rotator cuff tendon tears between junior and experienced musculoskeletal (MSK) radiologists. Also, to compare the overall ultrasound accuracy referenced to MRI. Methods A retrospective data collection for patients with clinically suspected rotator cuff tears who underwent ultrasound from June 2021 - June 2023 was conducted. ⋯ Sensitivity, specificity, positive (PPV) and negative predictive values (NPV), and accuracy of US interpreted by junior vs experienced MSK radiologists for supraspinatus full thickness tears (FTTs) were 100% vs 91%, 90% vs 93%, 79% vs 83%, 100% vs 97%, and 93% vs 93%, respectively. After the second consensus, sensitivity, specificity, PPV and NPV, and accuracy were 91%, 90%, 77%, 96%, and 90%, respectively. Conclusion The accuracy of shoulder ultrasound in diagnosing supraspinatus FTTs by junior MSK radiologists compares well to the more experienced ones, but not for partial thickness tears (PTTs).

Aim Stroke treatment is a time-critical condition. Understanding the impact of timing and types of treatment on patient outcomes can help develop and optimize stroke management strategies. The study aimed to analyse the effect of different time intervals and mechanical thrombectomy methods on outcomes of stroke patients in Kazakhstan. ⋯ Our results demonstrated a statistically significant decrease in NIHSS, mRS after surgical treatment compared to baseline. The association between the extended time from stroke onset to hospitalization and reduced survival rates was observed. Conclusion Our findings indicate the essential role of timely intervention in managing stroke patients, as well as the need for a comprehensive and patient-centred approach to stroke care.

Aim Significant risk factors for femoral nail cutout are well-documented, primarily in the context of single-screw proximal nails. However, it remains uncertain whether those same risk factors are applicable when considering different implant devices. The aim of this retrospective cohort study was to compare cutout risk factors between single- versus double-screw proximal femoral nails. ⋯ Conclusion This study provides insights into the choice of nail systems for intertrochanteric femur fractures, highlighting the importance of distal locking configurations and TAD values. The double screw nail exhibits quite a tolerance by having a higher average TAD value. These findings may guide clinical decisionmaking in the treatment of this challenging fracture type.

Aim Kyphoplasty and vertebroplasty are minimally invasive procedures used in bone augmentation following vertebral fractures when conservative management has failed. Cement injection could leak into surrounding structures leading to post-operative sequelae, which could be symptomatic. This study compared the rate and site of cement extravasation in vertebroplasty, kyphoplasty, and a combined approach. ⋯ Bone metastases were the aetiology with the highest cement leakage rate (27.5%). Conclusion The use of kyphoplasty alone or in conjunction with vertebroplasty decreases the risk of cement extravasation and subsequent complications compared to vertebroplasty alone. The use of pedicle screws appears to be safe and was not found to increase the risk of cement extravasation.

Aim To study the character of blood circulation in the bone stump at tight and loose closure of the medullary cavity. Methods Two series of experiments on 39 rabbits with mid-third femoral amputation and muscular plasty were carried out. In the 1st (experimental) series, the bone scapula was closed by thin cortical autograft taken from the epimetaphyseal area, and then the muscles were sutured, and in the 2nd - the scapula was closed by myoplasty only. ⋯ Results In the 1st series there was a rapid restoration of the disturbed macro- and microcirculation due to the reserve sources of blood circulation and the development of extravascular ways of microcirculation. In the 2nd series, blood circulation recovery was significantly slower and occurred mainly due to the development of extravascular microcirculatory pathways. Conclusion The study established undeniable usefulness of tight closure of the bone marrow cavity during amputation.
