|
|
Term
|
Definition

|
|
Term
|
Definition

|
|
Term
|
Definition
| inflammation and irritation of lateral epicondyle (extensor carpi radialis, longus and brevis, extensor carpi ulnaris, extensor digitorum, supinator), results from activities that stress extensors and supinator |
|
|
Term

|
|
Term
