Abstract

We present the case report of a 21-year-old man with a late diagnosis of retrosternal dislocation of the sternoclavicular joint with a fractured sternal end of the clavicle.The first symptom leading to the diagnosis was dysphagia associated with physical activity.The diagnosis was based on computed tomography examination.In the first place, the fragment of the medial clavicular end was fixed with two screws.During surgery the sternoclavicular joint was wrongly identified; this fact was revealed by the following radiographic examination.On revision surgery, the sternoclaviculr ligament was reconstructed using a semitendinosus tendon graft.The reconstructed ligament was augmented with two Orthocord sutures running between the clavicle and the first rib.At 2 years after surgery the functional outcome and sternoclavicular joint stability were excellent Key words: dorsal sternoclavicular fracture dislocation, ligament reconstruction, dysphagia, semitendinosus, graft. ÚVODSternoklavikulární (SC) kloub patří mezi složené sedlové klouby pohyblivé ve 3 rovinách, hybnost v kloubu jsou 30-35º elevace v koronální rovině a 35º předozadní pohyb v transversální rovině, 45-50º rotace v longitudinální ose (14).Kloubní plochy si vzájemně neodpovídají.Nestejný tvar je vyrovnán diskem.Stabilita kloubu je závislá na integritě kloubního pouzdra zesíleného lig.sternoclaviculare anterius a posterius, dále lig.costoclaviculare a interclaviculare a m.subclavius (6).Jako dominantní stabilizační struktura se jeví ligamenta stabilizující disk -tj.lig.sternoclaviculare (1).Nestabilita SC kloubu může vzniknout akutně úrazovým mechanismem, nebo chronicky následkem laxity vazů či následkem jiných afekcí například osteonekrózy mediálního konce klíčku (Friedrichovo onemocnění), artritid, mediastinitidy a SAPHO syndromu (13, 18).
