Skier’s Thumb

The thumb of a skier is a group of symptoms resulting from an injury leading to the rupture of the posterior intercostal artery. This disease occurs mainly in people who are at risk of hand injuries (e.g. goalkeepers, skiers or rugby players), as well as in less physically active people. In this case, the thumbs of the skier arise as a result of prolonged and systematic loading of the joints of the fingers.

The symptomatic course of this type of ulnar collateral ligament injury of the thumb demonstrates a high degree of consistency regardless of the trauma’s initial etiology. During the acute phase, pronounced soft-tissue edema and subcutaneous ecchymosis develop, localized to the metacarpophalangeal joint region. Patients additionally report significant impairment of grip strength in the affected hand, rendering the manipulation of heavier or bulkier objects highly challenging. Further diagnostic indicators include: radiating pain along the ulnar aspect of the thumb’s base, a palpably displaced first metacarpal head, and an abnormal ulnar deviation of the thumb upon active flexion attempts.

The management of skier’s thumb syndrome is primarily determined by the severity of the injury and the elapsed time since the traumatic event occurred. In cases of acute and recent trauma, the initial therapeutic measure should involve the application of an intense cold compress with ice, which serves to constrict blood vessels and thereby reduce the likelihood of inflammatory responses and subsequent tissue swelling. Following this, continuous monitoring of symptoms is essential—if pain, swelling, or restricted mobility persist beyond a few days, a medical consultation is necessary to conduct a thorough diagnostic evaluation. The most effective initial diagnostic tool is an X-ray (RTG), which provides a clear assessment of bone integrity and potential fractures. Supplementary evaluations should include ultrasonography (USG) and a manual examination of ligamentous stability to fully comprehend the injury mechanism. The anticipated recovery period for mild to moderate sprains or strains of the ulnar collateral ligament of the thumb typically ranges from four to six weeks. During this interval, physiotherapeutic interventions can be employed to accelerate tissue healing and restore full joint functionality. Should conservative treatment fail to yield satisfactory results after approximately three weeks, surgical intervention may be considered. Absolute indications for surgery include advanced pathological changes such as bone fragment rotation, a Stener lesion (displacement of the torn ligament), or articular surface incongruities that impede normal joint movement. The surgical procedure generally involves ligament reconstruction through reattachment or suturing of torn segments in cases of central ligament damage.
