When you break your scaphoid wrist bone, how often is a ligament also torn?

If you break the small scaphoid bone in your wrist, a common worry is whether you've also torn a crucial ligament that could lead to long-term arthritis. Doctors looked back at data from 439 patients who had this specific, minimally displaced fracture to see how often this happened. They found that a ligament tear severe enough to create a visible gap on an X-ray was actually quite rare—it affected the scapholunate ligament in about 3% of cases and the lunotriquetral ligament in none at all. Even more reassuringly, in the patients they could follow for five years, these gaps didn't get any wider over time. This suggests that for the vast majority of people with this specific type of fracture, focusing treatment on healing the bone itself is likely sufficient. It's important to note this analysis only included fractures with very little displacement, so the findings might not apply to more severe breaks. Also, the study relied on standard X-rays, so it's possible some subtle ligament injuries were missed, though any that were didn't seem to cause progressive damage.
