Fracture of the Volar Lip of the Lunate in the Face of Perilunate Injury. Report of Three Cases and Review of Literature

Lunate fractures associated with perilunate dislocation are very rare.The diagnosis is often difficult as is the treatment itself.Up to 25% go on to be undiagnosed in the emergency room (ER) setting.We present 3 very different cases of perilunate dislocation with lunate volar lip fracture occurring in the different hospitals around the world (Spain, Colombia and Chile).All 3 were diagnosed in the ER, however the treatments differ.We aim to show the spectrum of treatment of these high energy lesions either acute or chronic and the outcomes of these.
