History: 51 year old female with right thumb pain that had been present for over a year.  Although it began after a fall, x-rays showed arthritis at the base of the thumb (CMC joint arthritis).  After trying splinting, a steroid injection, and anti-inflammatory medication, she elected for surgery to alleviate her pain. 

Diagnosis: Right thumb CMC arthritis

Treatment: Right thumb trapezium excision with ligament reconstruction and tendon interposition (LRTI)

Outcome: Her recovery proceeded smoothly and by 5 months after surgery she had regained full motion, had returned to all her activities, and no longer had any pain.  She was very happy.
