Injuries of the scapholunate ligament are common amongst the young and active population (Pappou, Basel and Deal, 2013). Scaphoid and lunate are both part of the wrist bones.
The scaphoid bone is a wrist bone located at the base of the thumb and the lunate adjacent to it the scapholunate ligament stabilizes the joint.It is a intra-articular ligament, that lies in synovial fluid, which contributes to its poor healing potential. It is responsible for controlling rotational motions, constantly stabilizing
Injury is caused when the wrist is forcibly hyperextended, which disrupts the adjacent scapholunate ligament.
Management involves following the PRICE regime and stabilisation of the joint. When instability occurs, surgical repair has improved over the last couple of years, which allows a more anatomic reconstruction of the ligament (Pappou, Basel and Deal, 2013). If left untreated, the injury develops a chronic showing of pain and an extension deformity of the affected wrist bone (Miller, Hart and MacKnight, 2010).
