When Too Much Healing Becomes a Stress Fracture Problem
Can a stress fracture actually heal with too much bone? Yes - and in some runners, that extra bone canbecome a problem of its own. In this episode of the Doc On The Run Podcast, Dr. Christopher Segler explains why a very large bone callus does not always mean a stress fracture is safely healed. He walks through two runner cases: one in which a large callus hid an unstable fracture heading toward nonunion, and another in which prolonged irritation produced a completely healed but excessively thick metatarsal that crowded the surrounding soft tissues. In this episode you'll learn: • Why bone callus forms around a stress fracture • How continued motion can create a deceptively large callus • Why a big callus can coexist with an unstable fracture or nonunion • How prolonged irritation can leave a healed bone too thick • Why excess bone can crowd muscles, nerves, and other soft tissues • Why simply “running less” may not reduce stress enough • What pain, bruising, and swelling can tell you about injury severity • Why measuring improvement matters before you increase activity
