Introduction: within musculoskeletal disorders there are, with high frequency, conditions that affect the shoulder and knee joints; in its diagnosis, ultrasound is of vital importance as an auxiliary means. Objective: to characterize shoulder and knee affections by ultrasound. Methods: a descriptive and cross-sectional study was carried out in the Imaging Service of the "Arnaldo Milián Castro" Hospital in the Province of Villa Clara. The population was made up of all the patients (434) referred to the Ultrasound Clinic of the osteomyoarticular system during the period from October 2018 to July 2021. The historical and inductive-deductive methods were used, as well as the documentary analysis of clinical histories and reports. ultrasonographic, observational and statistical. Results: shoulder and knee conditions affected mainly those aged 50 to 59 years, the most frequent shoulder condition was omarthrosis and calcifications and tendinitis prevailed in supraspinatus lesions. Knee conditions were more frequent at 60 years of age and over, and gonarthrosis predominated, significantly related to the popliteal cyst, and lateral and medial ligament injury. The agreement between diagnostic impression and ultrasonographic diagnosis was good for the shoulder and moderate for the knee. Conclusions: ultrasound was a useful means to characterize shoulder and knee conditions. [ABSTRACT FROM AUTHOR]

Introduction: according to the literature there are discrepancies between the findings on ultrasound, nuclear magnetic resonance and arthroscopy, which is why the latter is considered the gold standard for the diagnosis of lesions of internal structures of the knee. Objective: to evaluate the relationship between the echo, nuclear magnetic resonance and arthroscopy in meniscal lesions. Method: a descriptive and observational study was carried out at the "Arnaldo Milián Castro" Hospital in the Province of Villa Clara between January 2015 and March 2017. Results: 33.3% of the patients were between 40 and 49 years old and 77.7% were male. In 58.7% the affected knee was the right and in 86.1% the cause was nontraumatic. According to the location of the meniscal rupture, the greatest number of lesions of the medial meniscus was diagnosed by NMR (61%) and US (58%), those of the lateral meniscus were diagnosed by US (41%) and arthroscopy (39%). Ultrasound and resonance showed good agreement for the location and the exact point of the lesion. Conclusions: the correlation was very good for the variables analyzed between the three diagnostic methods, the largest being between magnetic resonance imaging and arthroscopy due to the coincidence index detected between them.
