Background: We present a case series of high-level baseball players having sustained a rare, isolated injury to the fourth carpometacarpal joint of the nondominant or bottom hand during a jammed swing.
Methods: Ten patients were evaluated for ulnar-sided wrist pain and were subsequently diagnosed with fourth carpometacarpal joint synovitis based on physical examination and magnetic resonance imaging revealing increased signal intensity within the joint.
Results: Conservative treatment modalities including rest, nonsteroidal anti-inflammatory medications, splinting, and corticosteroid injections resulted in return to play within 4 weeks for all patients.

Age-adjusted incidence rates of female breast cancer from the surveillance, epidemiology, and end results (SEER) program of the US National Cancer Institute were collected and analyzed using SEER*Stat 8.3.
