目的：分析前臂良性骨肿瘤的流行病学特征及影像学特点，提高对前臂良性骨肿瘤的认识及诊断水平。方法回顾1959年11月至2014年3月，北京积水潭医院肿瘤科收治的215例前臂良性骨肿瘤患者资料，记录患者的年龄、性别，分析前臂良性骨肿瘤的好发年龄、性别比例；回顾病理及影像资料，确定肿瘤的病理类型、解剖部位、影像学特点；综合上述资料按性别、年龄、肿瘤类型、发生部位、影像学特点进行统计，分析各类前臂良性骨肿瘤的流行病学特点。结果共215例前臂良性骨肿瘤，尺骨52例，桡骨163例；男132例，女83例，男：女为1.6∶1；发病年龄4～63岁，中位年龄26.0岁，平均27.9岁，20岁以下病例50例(23.26%)，21～30岁79例(36.74%)，31～40岁60例(27.91%)，41～50岁19例(8.84%)，50岁以上7例(3.26%)。较多见的有骨巨细胞瘤140例(65.12%)，骨软骨瘤23例(10.70%)，骨样骨瘤16例(7.44%)，骨纤维结构不良14例(6.51%)，动脉瘤样骨囊肿6例(2.79%)，其它还包括非骨化性纤维瘤、单纯性骨囊肿、内生软骨瘤等。骨巨细胞瘤好发于尺桡骨远端骨端，骨软骨瘤及动脉瘤样骨囊肿好发于尺桡骨远端干骺端，骨样骨瘤及纤维结构不良好发于尺桡骨骨干及近端干骺端；骨巨细胞瘤及动脉瘤样骨囊肿具有较强侵袭性，可呈中心或偏心生长。结论前臂良性骨肿瘤以骨巨细胞瘤最为多见，好发于尺桡骨远端骨端，综合流行病学情况及影像学研究有利于疾病的诊断和鉴别诊断。

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.
