Describe your assessment plan for this patient (rib fracture versus rib hypomobility).

1. A 26-year-old male ice hockey player comes to you complaining of back pain that is referred around the chest. He explains that he was “boarded” (hit between another player and the boards). He did not notice the pain and stiffness until the next day. He has had the problem for 2 weeks. Describe your assessment plan for this patient (rib hypomobility versus ligament sprain).

2. A 21-year-old female synchronized swimmer comes to you complaining of pain in her side. She says she was kicked when she helped boost another athlete out of the water 5 days ago. Describe your assessment plan for this patient (rib fracture versus rib hypomobility).
