Case:
We present the case of a twenty-one-year-old right-hand-throwing, right-hand-batting female softball pitcher who presented with a three-month history of right rib pain. A bone scan showed increased uptake in the lateral aspect of the right seventh rib, consistent with a stress fracture. The patient was managed nonoperatively and made a full recovery.
Conclusion:
The forces created by the attachment of the serratus anterior during underhand throwing are the likely etiology of the injury in our patient. Physicians should maintain a high clinical index of suspicion for stress fracture in underhand athletes with lateral rib pain.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
