 ====== Lateral epicondylitis ======
+Lateral epicondylitis is an overuse syndrome affecting the common extensor tendon at the lateral epicondyle of the humerus, most commonly the extensor carpi radialis brevis (ECRB).
+===== Etiology =====
+  * Repetitive wrist extension and forearm supination
+  * Microtrauma to the ECRB origin
+  * Common in:
+    * Tennis players
+    * Manual laborers (e.g., carpenters, mechanics)
+    * Office workers (e.g., typing, mouse use)
+===== Clinical Presentation =====
+  * Pain and tenderness over lateral epicondyle
+  * Pain exacerbated by:
+    * Gripping
+    * Lifting with pronated forearm
+    * Wrist extension against resistance
+  * Positive special tests:
+    * Cozen’s test
+    * Maudsley’s test
+===== Diagnosis =====
+  * Clinical diagnosis
+  * Imaging (if needed to rule out other causes):
+    * Ultrasound: hypoechoic areas in tendon
+    * MRI: tendinosis, partial tearing
+===== Treatment Options =====
+^ Treatment Type ^ Examples ^ Notes ^
+| Conservative | Rest, ice, NSAIDs, physical therapy | First-line; effective in most cases |
+| Bracing | Counterforce brace or wrist splint | Reduces stress on tendon |
+| Injections | Corticosteroids \\
+PRP (platelet-rich plasma) | Corticosteroids = short-term relief; \\
+PRP = possible long-term benefit (mixed evidence) |
+| Surgery | Tendon debridement and ECRB release | For refractory cases >6–12 months |
+===== Prognosis =====
+  * Most patients improve with conservative management
+  * Symptoms can persist for several months
+  * Recurrence if overuse continues
