Summary
A painful buttock lesion in a young athlete was diagnosed as myositis ossificans (MO). Treatment with rest, NSAIDs, and extracorporeal shock wave therapy (ESWT) led to a full recovery and return to sports.
Area of Science:
- Pediatric Sports Medicine
- Musculoskeletal Radiology
- Orthopedic Surgery
Background:
- A 13-year-old female athlete presented with a painful right buttock lesion impacting her sports participation.
- Initial physiotherapy was ineffective, prompting further investigation.
Observation:
- Physical examination revealed a tender mass in the right buttock.
- Musculoskeletal ultrasound showed a large hypoechoic lesion.
- MRI findings of calcification were inconclusive for malignancy.
Findings:
- Histological examination confirmed myositis ossificans (MO), a benign condition.
- The patient experienced significant improvement within three months.
- Treatment included rest, NSAIDs, and extracorporeal shock wave therapy (ESWT).
Implications:
- Differentiating MO from other soft tissue lesions requires comprehensive radiological and histological evaluation.
- Effective management can enable athletes to return to pain-free, active lifestyles.
- ESWT is a valuable therapeutic option for MO management in athletes.

The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
