My 17 yr. old son, junior catcher on varsity, just had hamate hook excised yesterday. Terrific surgeon Dr. Steven Shin diagnosed and confirmed with a CT scan - which apparently is the most efficient way to see the fracture. The last 6 months have been very frustrating as my son's "sports" doctor misdiagnosed his wrist and palm pain and relied only on Xray and one MRI (that indicated a bruised hamate but no fracture). So the result was my son spending 4 weeks then resuming to play only to experience pain. Finally decided to go to a specialist at Kerlan Jobe clinic in Los Angeles. Dr. Shin went right to the pain points on my son's palm then ordered a CT scan to confirm the break. He explained that MRIs are actually too thorough often times to see this injury.
We're confident our son is on the right course for recovery and are hopeful he can resume play in 6 weeks or so - and not miss his entire season. Hope this story helps anyone in a similar situation.
