Bone graft and cement were used in 53 (77.9%) and 15 (22.1%) patients, respectively. Prophylactic internal fixation was performed in 63 (92.7%) patients. The median (IQR) follow-up duration was 42 (30\u201364) months. Normal imaging findings were identified at follow-up in 45 patients (66.2%). Our reported complications included peri- (2.9%) and post-operative (8.8%) bone fractures, incomplete bone graft integration (24.5%, out of patients treated with bone grafting), cement loosening (26.7%, out of patients treated with cementation), fixation hardware rupture (1.6%) or loosening (6.3%, out of patients treated with internal fixation) and residual disease (1.5%). Incomplete bone graft integration and cement loosening were associated with tumor location in the humerus (p\u2009=\u20090.023).
