Evaluation and characterization of concurrent carpal bone fractures in distal radius fractures
Journal Title: International Journal of Orthopaedics Traumatology & Surgical Sciences - Year 2016, Vol 2, Issue 2
Abstract
Background: Aim of the study was to evaluate the incidence and characteristics of carpal bone fractures occurring concurrently with distal radius fractures. Methods: We retrospectively analyzed 260 patients with distal radius fractures who were treated between May 2013 – May 2016 at St. John’s Medical College Hospital, Bangalore. AP, lateral and oblique radiographs of the wrist were examined and CT was done to rule out carpal bone fractures. We evaluated the frequency and characteristics of carpal bone fractures occurring concurrently with distal radius fractures with the AO classification and patient factors age and gender. Results: 66 cases (25.3%) had simultaneous carpal bone fractures of one or more bones in the 260 distal radius fractures we encountered. Fall on an outstretched hand with extended wrist was the commonest mechanism of injury.The distribution of carpal bone fractures were 30 cases in the triquetrum, 18 in the lunate, 14 in the scaphoid, 7 in the hamate and 5 in pisiform.Hamate was the only carpal bone fractured in the distal row of carpals. Conclusion: The incidence of concurrent carpal bone fractures in distal radius fractures was significant. Almost all carpal fractures had no or minimal displacement. Suspicion of carpal fractures occurring concurrently with distal radius fracture should be high. CT should be considered for the diagnosis as misdiagnosed or untreated carpal bone fractures may have a poor surgical outcome with complications.
