Davies AM, et al. - A total of 387 individuals were recognized with a central cartilage tumor (CCT) in the proximal humerus, distal femur, and proximal tibia, who were referred to a single unit either from primary/secondary care or tertiary care straight to Royal Orthopaedic Hospital which is a specialist orthopedic oncology service over a period of 10-year, in order to authenticate an imaging protocol for the management of solitary CCTs of the proximal humerus and around the knee. With ascending Birmingham Atypical Cartilage Tumour Imaging Protocol (BACTIP) a rise in the incidence of malignancy (chondrosarcoma) was noted. A 100%, 96%, and 83% benign diagnosis (enchondroma) in types IA and IB, in IIA, and in IIB, respectively, was observed. Of type IIC and type III, 57% and 97% were diagnosed as malignant. Just in one case would the application of the protocol have resulted in a 5-month delay in the diagnosis of chondrosarcoma. Therefore, this retrospective study authenticates that in the primary evaluation of CCT in the proximal humerus and around the knee with the exception of the proximal fibula, the BACTIP is a beneficial tool for the general radiologist. Especially, it also aids in ascertaining which cases require immediate referral to a specialist orthopedic oncology service for additional evaluation.
