Blocker's Exostosis

Blocker's Exostosis, also known as Arm Exostosis, is a bony growth (exostosis) that occurs on the humerus (upper arm bone) or radius/ulna (forearm bones).

Causes:

1. Repetitive trauma or stress from throwing or blocking activities

2. Overuse or fatigue

3. Genetics

4. Abnormal bone growth

Symptoms:

1. Pain or tenderness on the affected arm

2. Swelling or redness

3. Limited mobility or stiffness

4. Bony lump or growth

5. Weakness or fatigue

Treatment:

1. Rest and ice to reduce pain and inflammation

2. Physical therapy to improve mobility and strength

3. Pain management with medication

4. Surgery to remove the exostosis (if necessary)

5. Modification of throwing or blocking techniques

Prevention:

1. Proper warm-up and cool-down exercises

2. Gradual increase in throwing or blocking intensity

3. Strengthening exercises for the arm and shoulder

4. Use of protective gear (e.g., arm guards)

5. Regular breaks to avoid fatigue

Complications:

1. Fracture or breakage of the affected bone

2. Nerve damage or compression

3. Chronic pain or stiffness

4. Limited mobility or function
