ARTHROSCOPIC CURETTAGE OF INTRAOSSEOUS LUNATE BONE CYST : A CASE REPORT AND TECHNICAL CONSIDERATION

Intraosseous lunate bone cysts are rare benign lesions that can cause significant wrist pain and functional impairment. Various treatment modalities have been described, including open surgical techniques and arthroscopic approaches. Incisions for an arthroscopic procedure are extremely small. Therefore, compared to open surgery, the patient experiences less pain, less blood loss, less swelling, less inflammation, and smaller scars. This case report presents the successful management of an intraosseous lunate bone cyst using arthroscopic curettage.

A 49-year-old female presented with a six-month history of progressively worsening right wrist pain and limited range of motion. Radiographic imaging revealed a well-defined intraosseous lunate bone cyst. After failed conservative management, the patient underwent arthroscopic curettage of the cyst under general anesthesia. The procedure involved access through standard portals and identifying the accurate location of lunate with wire guiding and fluoroscopic control careful curettage and grafting of the cystic lesion using arthroscopic instruments.

Arthroscopic curettage of the intraosseous lunate bone cyst was well-tolerated, with minimal intraoperative bleeding. Postoperatively, the patient was placed in a splint for two weeks, followed by a structured rehabilitation program focusing on range of motion and strengthening exercises. The evaluation, which was completed by self-report using The Disabilities of the Arm, Shoulder, and Hand (DASH), provided total score of 2.5/100, and Patient rate wrist/hand evaluation (PRWHE) provided total score of 15/100, where both things showed significant improvement

Arthroscopic curettage of intraosseous lunate bone cysts can be a safe and effective treatment, providing symptomatic relief and functional improvement.
