Arthroscopic Ablation of Osteoid Osteoma in the Wrist

-

  Osteoid osteoma is a benign bone tumor that rarely involves joints. Although there are several reports of arthroscopic osteoid osteoma excisions, to our knowledge, there are no reports of this type of treatment for osteoid osteoma in carpal bones. We report two cases of arthroscopic (a person who had a pain in the left wrist and the other one with carpal tunnel syndrome) with excision of osteoid osteoma in the carpal bones. We think arthroscopic excision is the best choice for treatment as long as the tumor is accessible for arthroscopic surgery, when osteoid osteoma has classic clinical and imaging findings and is near an articular surface. However, when the tumor is far from the joint surfaces, when we need pathologic confirmation or when the tumor is easily accessible using a non-articular approach, arthroscopic excision may not be the most appropriate technique.
