Relationship between isolated lunate cysts and scapholunate ligament lesions

Intraosseous ganglion cysts of the lunate are usually asymptomatic, but when symptomatic, they are a rare cause of chronic wrist pain. The standard treatment of these cysts adjacent to the scapholunate ligament is curettage and grafting using open techniques. These techniques may result in postoperative stiffness and vascular disorder. Arthroscopic techniques are a more reliable choice in the prevention of these complications. In this study, we aimed to evaluate the functional outcomes of patients who underwent arthroscopic curettage grafting due to intraosseous ganglion cyst in the lunate and the association of scapholunate ligament damage. Our study is a retrospective study. Eighteen patients with intraosseous cysts in the isolated lunate and treated with arthroscopic curettage and grafting were included in the study. Preoperative and postoperative joint range of motion, Modified Mayo wrist scores, VAS scores and grip strength were recorded. The patients were followed up for an average of 25 months (18-52). Arthroscopic dorsal capsulodesis was applied to patients with scapholunate ligament injury. In these study had scapholunate ligament lesions and were observed and trated fifteen patients. It was observed that there was a significant improvement in the modified wrist scores, VAS scores and grip strength compared to the preoperative period. It was observed that the joint range of motion did not change significantly. All of the patients recovered and no recurrence was observed. We did not encounter any complications. In conclusion, the treatment of intraosseous ganglion cysts in the lunate seems to be satisfactory with developing arthroscopic techniques. It should also be kept in mind that it may be associated with scapholunate ligament lesions and can be treated in the same session.
