Acute carpal instability can present a difficult management problem for the surgeon. Our knowledge of carpal instability has improved, primarily as a result of an improved understanding of wrist anatomy, biomechanics, and the postulated pathomechanics of the common instability patterns. This review will discuss the prevailing understanding of carpal instability, with an emphasis on the commonly encountered patterns- isolated scapholunate injuries, perilunate injuries, and lunotriquetral injuries.
