A Case with isolated pain and swelling at the base of the left thumb is reported. The problem had lasted for 2 years, and it was getting worse with increasing pain also at the base of the right thumb. The X-ray showed a subluxation and an arthritis of the first CMCJ was diagnosed in left hand. An excision arthroplasty was successfully carried out. The excessive mobile phone use with active texting had been probably the main cause of the problem. Many, especially youngsters use their phones to text and play games a lot. The purpose of this report is to make the researchers and practitioners aware of this problem and to encourage them to record these cases that may be common in future.
