Outcomes of Surgical Management of Intraosseous Ganglia of the Carpal Bones: A Case Series.

ABSTRACT

BACKGROUND: Intraosseous ganglia of the carpal bones are uncommon with sparse publications to guide treatment. The purpose of this study was to review a single-institution experience to determine the outcomes of patients with surgically treated intraosseous carpal ganglia. METHODS: Skeletally mature patients with intraosseous carpal ganglia between 1995 and 2016 treated operatively were identified. Demographic information, clinical data, and radiographic studies were evaluated. RESULTS: Thirty-three ganglia in 31 patients were identified. Intraosseous ganglia were located in the lunate (23), scaphoid (9), and trapezoid (1). Patients who presented with pathologic fracture or collapse had larger intraosseus ganglia than those presenting with pain alone. Surgery significantly improved pain. Patients treated with debridement with autograft bone graft had a higher consolidation rate compared with allograft bone but no difference in pain. CONCLUSIONS: Patients with large or symptomatic lesions can be treated successfully with curettage and debridement, which leads to relief of pain. The use of bone grafting remains controversial.
