ABSTRACT

Introduction: dislocations of carpal bones without associated fractures are considered a rare injury, the most common mechanism of injury being axial loading with wrist in extension plus ulnar deviation. The literature reports a wide variety of complex carpal injuries, even so, it is possible to identify previously undescribed injuries. Objective: to present an atypical case of a patient with an injury to the midcarpal stabilizing mechanism and the stabilizing mechanism of the proximal row of the wrist following trauma to the hand that required carpectomy as definitive surgical treatment. Presentation of case: a 48 year old male patient is presented who is admitted to our hospital unit after presenting injury to the left hand after being run over by a motor vehicle, with axial load mechanism, presenting deformity in the left thoracic extremity, fracture of the proximal metaphysis of the second phalanx of the third finger as well as dislocation of the proximal interphalangeal joint, with traumatic amputation of the second phalanx of the fourth finger plus extensor injury in zone V of the fifth finger with loss of skin coverage of the fourth and fifth finger, attending our hospital unit 24 hours after the injury. Conclusions: carpal bone dislocations are an orthopedic emergency, with 20% going unnoticed in trauma centers. Early closed reduction is the initial treatment to avoid severe complications, however, surgical treatment is the gold standard for fixation. Carpectomy is considered a mostly adequate sequelae management treatment, however it is well accepted for complex injuries to the wrist stabilization mechanisms, as it can be performed in a short surgical time and early rehabilitation can be initiated and functional ranges of motion can be achieved with low sequelae.
