The scapholunate interosseous ligament (SLIL) is a crucial stabilizing structure of the wrist. Damage to this ligament often results from falling upon an outstretched hand, leading to carpal instability­.1,2,3 Tears to the SLIL create a gap in the scapholunate joint and allow the scaphoid to flex and the lunate to extend, rather than moving with one another as they do in healthy physiologic motion.4,5 The SLIL is normally repaired following injury in order to decrease the risk of arthritis and pain.1,2,5,6,7 Patients will often begin rehabilitation exercises after SLIL repair in order to reduce recovery time.8,9 In high activity patients, such as athletes, a pushup regimen of gradually increasing difficulty is often implemented to strengthen the upper body for rehabilitation.9 We hypothesize that normal military style pushups, with the wrist in extension, produce greater loads on the scaphoid and lunate than pushups performed with the wrist in neutral.
