Presentation consists of acute medial elbow pain with associated loss of command, control, and throwing velocity in pitchers. Attention should be given to associated risk factors including workload. Ulnar neuritis is a commonly associated condition because of its close proximity to the posterior band of the ulnar collateral ligament. Physical examination focuses on the ulnar collateral ligament, but also identifies associated pathology and kinetic chain factors that may predispose a player to injury. Tears are classified by location (proximal, midsubstance, distal) and extent (partial versus full thickness).

Generally, outcomes of surgical treatment have been superior to those of nonsurgical treatment for active individuals and the general population. Surgical treatment options include primary repair, reconstruction, or augmentation. However, the ideal timing of treatment, both surgery and rehabilitation, is unclear. Options include acute (ie, within 3 weeks), subacute (3 to 8 weeks), and delayed treatment of all ligaments simultaneously, or alternatively managed in two stages. Primary repair can be considered in avulsion injuries of the posterior cruciate ligament and posteromedial corner and distal posterolateral corner avulsions; however, treatment paradigms are still evolving. Reconstruction is preferred in younger patients, for most midsubstance injuries and cruciate ligament injuries, and when presentation is delayed. Early surgery may be associated with better outcomes and a lower incidence of cartilage lesions compared with delayed surgery, although there may be an increased risk of arthrofibrosis. More traditional protocols often restrict weight bearing in the first weeks to protect ligament healing. Although early range-of-motion exercises decrease the risk of stiffness following surgery for multiligamentous knee injury, concern remains regarding attenuation or loosening of the surgically repaired or reconstructed ligaments. The Surgical Timing and Rehabilitation trial has been designed to assess the outcomes of early versus delayed surgery and early versus delayed rehabilitation.</p>","PeriodicalId":73392,"journal":{"name":"Instructional course lectures","volume":"74 ","pages":"129-140"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142916479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For zone II injuries, the tendons are often amenable to surgical repair with extension splinting for 6 weeks.

FRIs can span a wide range of severity, and only recently has the international community come to a consensus on specific definitions and guidelines for treatment. Principles of FRI management include identification of at-risk injuries with correction of modifiable risk factors, the achievement of adequate bony union and fracture healing, thorough eradication of the offending microorganism, and restoration of function.
