summary Valgus Extension Overload, also known as Pitcher's elbow, is a condition characterized by posteromedial elbow pain related to repetitive microtrauma in throwing athletes. Diagnosis is made clinically with posteromedial elbow pain that worsens with elbow extension, and confirmed with radiographs showing osteophyte formation in the posteromedial olecranon fossa. Treatment is usually nonoperative with rest, activity modifications, and injections. Operative resection of osteophytes and loose bodies are indicated in pitchers with persistent symptoms. Epidemiology Demographics dominant arm of baseball pitchers Etiology Pathophysiology repetitive stress of pitching leads to excessive shear forces on medial aspect of olecranon tip and olecranon fossa lateral radio-capitellar compression posterior extension overload medial tension at MCL pathologic biomechanics leads to cartilage injury from repetitive impaction of olecranon into olecranon fossa osteochondral lesions of the capitellum osteophyte formation (posteromedial humerus and olecranon) loose bodies from fragmentation MCL can become attenuated with repetitive strain Associated conditions cubital tunnel syndrome concurrent cubital tunnel syndrome in ~25% of cases Presentation Symptoms pain in posteromedial elbow with full extension of elbow pain typically occurs in deceleration phase of pitch (sometimes during acceleration phase) loss of terminal elbow extension Physical exam tender to palpation over posteromedial olecranon crepitus pain with forced elbow extension flexion contracture Imaging Radiographs recommended views AP, lateral, oblique of elbow findings often show osteophyte formation in the posteromedial olecranon fossa loose bodies from fragmentation of capitellum possible calcium deposits on the substance of the MCL hypertrophy of the humerus - results in decreased space for articulation of olecranon process within the fossa CT shows osseous pathology best MRI helpful in evaluating associated injuries including partial/complete MCL tears Treatment Nonoperative NSAIDS, throwing rest, activity modification, steroid injections indications first line of treatment technique flexor-pronator strengthening pitching instructions to correct poor technique Operative resection of posteromedial osteophytes, removal of loose bodies, debridement of chondromalacia indications persistent symptoms that fail to improve with nonoperative treatment contraindications MCL insufficiency is a relative contraindication for olecranon debridement alone technique may be arthroscopic or open arthroscopy procedures can include debridement or drilling of chondromalacia, debridement of lateral meniscoid lesion or posterolateral plica, osteophyte excision, loose body excision care must be taken to only remove osteophytes and not normal olecranon as this many result in a loss of bony restraint and increase the tension in the MCL Complications Valgus instability resection of too much olecranon may cause valgus instability Ulnar nerve damage
