Scapholunate Ligament Injury

A ligament is a substantial band of connective tissue between two bones. The wrist has several ligaments. Sprains are used to describe injuries to ligaments. The scapholunate ligament is a ligament that is frequently hurt when a wrist is twisted. Between the scaphoid and lunate bones in the middle of the wrist is where this ligament is located (Figure 1). It is a crucial structural component for pain-free and complete wrist motion. The scapholunate ligament can be injured at several levels, from stretching to tearing.


Scapholunate ligament injuries frequently cause swelling and pain in the wrist, especially when performing certain activities. Additional signs include the ones listed below:

  • Pain when bending the wrist backward
  • Limited range of motion
  • Bruising
  • Pain and swelling that has developed over several days, usually on the back side of the wrist
  • Popping or grinding
  • Weakness in the wrist


When the wrist is subjected to a great deal of strain, the scapholunate ligament frequently ruptures. A fall onto the hand is a frequent cause. Usually, when the wrist is flexed backward or into an odd position, the ligament is harmed. The ligament may occasionally swell with time. This can be the result of recurrent stresses or age-related loosening. A persistent inflammatory condition may potentially gradually weaken the ligament. Chronic gout frequently injures this ligament.
