Department of Orthopaedic Surgery, Japan Community Healthcare Organization Osaka Hospital, Osaka, Japan.
Article Synopsis
- Sports activity can lead to elbow osteoarthritis (OA) and potentially worsen bone deformities, especially in athletes with osteochondritis dissecans (OCD), a condition that affects joint surfaces.
- A study involving 21 patients with sports-related elbow OA showed that those with a history of OCD had significantly larger bone deformities compared to those without OCD.
- The research concluded that the presence and size of OCD correlated with increased deformity in specific regions of the elbow, indicating that OCD aggravates the effects of elbow OA in athletes.

Department of Physical Therapy, Akita University Graduate School of Health Sciences, Akita, Japan.
Article Synopsis
- The study aimed to analyze medial elbow torque in youth baseball pitchers and assess the impact of prior elbow injuries on this torque during pitching.* -
- A sample of 171 youth pitchers aged 9-12 was grouped based on injury history, and the analysis showed that those with an injury within the last year exhibited higher medial elbow torque compared to a control group.* -
- The findings indicated that while higher ball velocity was linked to increased medial elbow torque, previous injuries alone did not significantly affect torque levels, suggesting that managing pitching velocity may help reduce injury risk.*

Department of Orthopaedic Surgery. Electronic address:
Article Synopsis
- Osteochondritis dissecans (OCD) of the capitellum is treated with marrow stimulation techniques, and MRI is used to evaluate the healing of cartilage but lacks a formal assessment system for this specific condition.
- This study analyzed postoperative MRI results of repair cartilage in patients with capitellar OCD and compared outcomes between those who were symptomatic and asymptomatic, using a classification system for cartilage repair tissue.
- The findings showed that 59% of cartilage defects were completely filled, but many had surface irregularities, with no significant differences between symptomatic and asymptomatic patients, and indicated challenges in correlating clinical scores with MRI results due to a small sample size.

Department of Orthopaedic Surgery, Gunma University Graduate School of Medicine, Maebashi, Japan.
Article Synopsis
- Osteochondritis dissecans (OCD) commonly affects young athletes, especially those engaging in repetitive overhead sports like baseball, with conservative treatment showing promise for spontaneous healing if the growth plates are still open.
- A case study of a 12-year-old male baseball player revealed OCD of the humeral capitellum, and after a diagnosis via ultrasonography, he was advised to avoid heavy elbow use and began conservative treatment.
- After 12 months of physiotherapy focusing on flexibility and core strength, the OCD lesion healed completely, suggesting conservative measures may be effective even with closed epiphyseal lines.

Radiographic evaluation of osteochondritis dissecans of the humeral capitellum: A systematic review.
J Orthop
September 2021
Department of Orthopedics, University of Maryland School of Medicine, 110 S. Paca Street, 6th Floor Suite 300. Baltimore, MD, 21201, USA.
Article Synopsis
- The study aimed to assess different radiographic classification systems for osteochondritis dissecans (OCD) of the capitellum and their effectiveness in correlating with findings during surgery.
- After analyzing 44 studies and 19 classification systems, it was found that MRI-based systems had a higher predictive value for intraoperative staging, particularly the Itsubo and Kohyama classifications for lesion stability.
- Ultimately, no single classification system reliably matched intraoperative results, suggesting that a combined approach using radiographs, MRI, and CT scans is necessary for accurately determining OCD lesion stability.
