Aim: Curettage and bone grafting are common methods in the treatment of tumor-like cysts in the bone. In this study, we present our
treatment results of curettage and bone grafting in patients with tumor-like bone cysts.
Material and Methods: Ninety-three patients (57 males, 36 females, mean age: 33 years; range: 3 to 67 years) who were diagnosed
with the tumor-like bone cysts in our clinic between march 2009 and December 2016, were evaluated. Curettage and bone grafting
treatment were applied to all patients. The efficacy of the treatments was evaluated according to the Neer/Cole classification, and
recurrence rates were recorded.
Results: Of the treated 93 patients, 35 had a non-ossifying fibroma (NOF), 22 had an aneurysmal bone cyst(ABC), 21 had a unicameral
bone cyst(UBC), and 15 had fibrous dysplasia(FD). Thirty-nine of these cysts were located in the femur,23 in the tibia, 22 in the
humerus, six in the fibula, and three in the radius. Recurrence rates were observed as 14.3% (n=3) in UBCs, 13.6% (n=3) in ABCs,
and 2.9% (n=1) in NOFs.In the tumor-like bone cysts, post-treatment complications were as follows: infection in five patients (5.3%),
wound site problems in 11 patients (11.8%), deformity, fracture, coxa vara, limitation of the range of motion, and lower extremity
shortness in nine patients (9.6%).
Conclusion: These study results show that curettage and bone grafting for the patients who are admitted to the hospital with tumorlike
lesions are effective and useful treatment modalities in the orthopedic oncology.
