Musculoskeletal · Overuse Injuries
The facts most likely to be tested
Medial epicondylitis is caused by repetitive overuse of the pronator teres and flexor carpi radialis muscles.
Patients present with medial elbow pain that is exacerbated by resisted wrist flexion and forearm pronation.
Physical examination reveals point tenderness directly over or just distal to the medial epicondyle.
The diagnosis is clinical, and imaging is generally reserved for cases that fail to improve with conservative management.
First-line treatment consists of activity modification, ice, NSAIDs, and a structured physical therapy program focusing on eccentric strengthening.
Chronic cases may be associated with ulnar neuropathy due to the proximity of the ulnar nerve to the medial epicondyle.
Corticosteroid injections are generally avoided in the acute phase due to the risk of tendon rupture and delayed healing.
Vignette unlocked
A 34-year-old male presents to the clinic complaining of persistent pain on the inside of his right elbow for the past 3 months. He is an avid golfer and reports that the pain worsens when he swings his club or performs repetitive wrist movements at his job as a carpenter. On physical examination, there is focal tenderness over the medial epicondyle. The patient experiences significant pain with resisted wrist flexion and forearm pronation. There is no evidence of sensory deficits in the fourth or fifth digits.
What is the most appropriate initial management for this patient?
Activity modification, ice, and physical therapy
The patient's presentation is classic for medial epicondylitis, and the first-line treatment is conservative management focusing on rest and eccentric strengthening as outlined in the fifth bet.

Etiology / Epidemiology
Overuse syndrome from repetitive wrist flexion and forearm pronation. Common in golfers, pitchers, and manual laborers.
Clinical Manifestations
Tenderness over the medial epicondyle exacerbated by resisted wrist flexion. Pain may radiate to the forearm.
Diagnosis
Primarily a clinical diagnosis. Imaging is reserved for refractory cases to rule out ulnar neuropathy.
Treatment
Conservative management (rest, ice, NSAIDs, bracing). Avoid corticosteroid injections due to risk of tendon rupture.
Prognosis
Most resolve with conservative therapy within 6-12 months. Surgical intervention is rarely required.

Epidemiology & Etiology
Occurs most frequently in patients aged 40-50 years. Primarily caused by microtrauma from repetitive valgus stress and forceful wrist flexion. Common in athletes performing overhead throwing or racquet sports.
Pertinent Anatomy
Involves the origin of the pronator teres and flexor carpi radialis muscles. The ulnar nerve runs posterior to the medial epicondyle and is at risk of secondary irritation.
Pathophysiology
Repetitive strain leads to angiofibroblastic hyperplasia at the common flexor tendon origin. Unlike inflammatory conditions, this is a degenerative tendinosis process rather than acute inflammation. Chronic micro-tearing results in collagen disorganization.
Clinical Manifestations
Patients report medial elbow pain that worsens with gripping or wrist flexion. Physical exam reveals point tenderness distal to the medial epicondyle. Ulnar nerve paresthesias in the 4th and 5th digits suggest concurrent cubital tunnel syndrome.
Diagnosis
Diagnosis is clinical. Provocative testing includes pain with resisted wrist flexion and forearm pronation. MRI is the gold standard for visualizing tendon thickening or tears if surgery is considered.
Treatment
First-line is activity modification and NSAIDs. Use a counterforce brace to offload the tendon. Corticosteroid injections are discouraged due to high risk of tendon atrophy and rupture. Physical therapy focusing on eccentric strengthening is the mainstay of long-term recovery.
Prognosis
Over 90% of patients improve with non-operative management. Failure to improve after 6-12 months of physical therapy may warrant surgical debridement of the diseased tissue.
Differential Diagnosis
Cubital tunnel syndrome: associated with ulnar nerve distribution paresthesias
Medial collateral ligament injury: associated with valgus instability
Cervical radiculopathy: associated with neck pain and dermatomal sensory loss
Lateral epicondylitis: pain localized to the lateral epicondyle with wrist extension
Osteochondritis dissecans: common in adolescent athletes with locking/catching
