Most cartilage forming tumors are benign and rarely affect the spinal canal, their principal location is in humerus metaphysis, femur and tibia. They represent 2% of all tumors and 2.6% of the benign tumors of the spine, usually located at the cervical spine. It is speculated that the secondary ossification center may be aberrant cartilaginous tissue that causes the formation of osteochondroma. From 1 to 4% of osteochondromas involve the spine and are commonly included in the posterior elements of the vertebrae and if located near neurological structures causing irritation and spinal compression is rare but potentially catastrophic. The average age of clinical onset is at the 2nd and 3rd decade of life.
50-year-old male who began his illness four years ago with pain in the lumbar region with right leg paresthesias, muscle strength 4/5 in the dermatomes L4 and L5, pain was increasing in intensity and frequently. The complete cure was to remove the exostosis of the lamina of right side of L4 with projection to the medullary canal and origin of the contact with the root of L4. We performed: clinical history, physical examination, X-rays, magnetic resonance imaging, electromyography, histology. It was performed: total removal of the tumor effectively and symptoms disappeared. As the spinal osteochondromas are rare and tend to occur in young adults.
大多数软骨形成性肿瘤是良性的，很少累及椎管，其主要部位在肱骨近端、股骨和胫骨。它们占所有肿瘤的2%，占脊柱良性肿瘤的2.6%，通常位于颈椎。据推测，继发骨化中心可能是导致骨软骨瘤形成的异常软骨组织。1%至4%的骨软骨瘤累及脊柱，通常累及椎体的后部结构，如果位于神经结构附近，引起刺激和脊髓压迫虽罕见但可能是灾难性的。临床发病的平均年龄在20至30岁。
一名50岁男性，四年前开始出现腰部疼痛伴右下肢感觉异常，L4和L5皮节的肌力为4/5级，疼痛强度不断增加且频繁发作。彻底治愈方法是切除L4右侧椎板的骨赘，其向髓管突出并与L4神经根接触。我们进行了：临床病史、体格检查、X线、磁共振成像、肌电图、组织学检查。进行了：有效彻底切除肿瘤，症状消失。由于脊柱骨软骨瘤罕见且倾向于发生在年轻人中。
