Abstract：Objective To deepen the understanding of benign forearm bone tumors and to improve the diagnosis through analyzing the epidemiological and radiological features of benign forearm bone tumors.Methods Data of 215 patients with benign forearm bone tumors who were adopted in our department from November 1959 to March 2014 were reviewed. The age and gender of patients were recorded, and the age group in which forearm bone tumors occurred frequently and the sex ratio were analyzed. The pathological data were reviewed to determine the pathological types of tumors. The radiological data were examined to determine the anatomic sites and radiological features of tumors. Based on the data stated above, epidemiological features of all kinds of benign forearm bone tumors were analyzed, with statistical analysis of gender, age, tumor types, positions and radiological features.Results There were 132 male patients and 83 female patients, and the ratio of males to females was 1.6 : 1. Age of onset was 4-63 years old. The median age was 26.0 years old. The mean age was 27.9 years old. Fifty patients were younger than 20 years old ( 23.26% ), 79 patients were of 21-30 years old ( 36.74% ), 60 patients were of 31-40 years old ( 27.91% ), 19 patients were of 41-50 years old ( 8.84% ) and 7 patients were older than 50 years old ( 3.26% ). The common tumors were giant cell tumor of bone ( 140 cases ), osteochondroma ( 23 cases ), osteoid osteoma ( 16 cases ), ifbrous dysplasia ( 14 cases ), aneurysmal bone cyst ( 6 cases ), non-ossifying ifbroma ( 4 cases ), simple bone cyst ( 3 cases ), enchondroma ( 3 cases ). Giant cell tumors of bone occurred frequently in distal epiphysis of radius and ulna, osteochondromas and aneurysmal bone cysts occurred frequently in distal metaphysis of radius and ulna, osteoid osteomas and ifbrous dysplasias occurred frequently in diaphysis and proximal metaphysis of radius and ulna. Giant cell tumors of bone and aneurysmal bone cysts were more invasive.Conclusions The most common benign forearm bone tumor is giant cell tumor of the bone, and the most frequent location is distal epiphysis of the radius and ulna. Theunderstanding of the epidemiological and radiological features is helpful for early diagnosis and differential diagnosis of benign forearm bone tumors.
