PurposeDetails regarding risk factors, onset, and outcomes for denosumab-related osteonecrosis (DRONJ) are sparse. This study examines the clinical characteristics and operative and non-operative therapeutic outcomes in patients with DRONJ not previously exposed to other antiresorptives.MethodsA retrospective medical record review was conducted, and data were collected, including clinical findings, management, healing outcomes, and radiologic, histologic, and micro-computed tomography (CT) analyses.ResultsSeventeen patients were treated with denosumab, with 14.1 ± 8.3 doses before DRONJ onset. The majority of lesions were observed at sites of dental prostheses (41%) and dental extractions (35%). Sixteen patients were managed non-operatively (10/16) or operatively (6/16) with either major (5/6) or minor surgery (1/6) and included in the follow-up analysis. Complete healing was significant in patients treated with major surgery (80%) compared to the non-operative group (20%; p<0.035). Denosumab was discontinued in 60% of non-operative patients and major surgery patients with no effect on healing. Histologic findings of 4 patients analysed exhibited a decreased number of osteocyte lacunae, and micro-CT of 3 patients scanned revealed trabecular thickening.ConclusionDRONJ lesions occurred mostly at sites of prostheses sores after a mean of 14 doses of denosumab. Major surgery demonstrated more complete healing than non-operative management, and denosumab cessation did not improve healing outcomes.
