Article Synopsis
- Researchers developed a computer-aided diagnosis (CAD) system using deep learning to detect osteochondritis dissecans (OCD) in ultrasound images of the elbow in baseball players.
- The study involved 196 players, with high accuracy results shown through confusion matrices and area under the curve (AUC) metrics on a separate external dataset.
- The CAD system demonstrated over 90% accuracy in detecting OCD across various ultrasound directions, indicating its potential to enhance OCD screenings in medical checkups.

Article Synopsis
- The study focuses on developing a deep learning model to help diagnose osteochondritis dissecans (OCD) in the humeral capitellum using ultrasound images, particularly beneficial for young throwing athletes.
- The proposed method utilizes YOLO for detecting the specific bone area and VGG16 for estimating the likelihood of OCD, achieving impressive accuracy metrics such as 0.890 for overall probability estimation.
- Results indicate that concentrating on the humeral capitellum enhances diagnostic performance and future research should evaluate the model's practical application in medical settings.
Background: Excessive elbow valgus stress can often cause pitching elbow injuries, and rehabilitation is usually required before an athlete can resume playing. However, there is a lack of information on the partial load rehabilitation of pitching elbow injuries caused by valgus extension overload based on elbow valgus stress. The purpose of this study was to clarify how quantitative partial elbow valgus stress while pitching affects ball velocity and subjective pitch-effort.

The disease was discovered by chance when evaluating a traumatic olecranon fracture. Radiography showed not only olecranon fracture but also a shortening of the epiphysis of the humeral trochlea and a segmental lesion with sclerosis.

We report a previously unrecognized ecological risk to marine organisms from waste tyres. Over 1 year, we made monthly counts of hermit crabs ( = 1278) invading and/or being trapped within six tyres anchored to the seabed at 8 m depth in Mutsu Bay, Japan.
