骨干为管状骨的中部，由坚硬的骨密质构成。因骨干周围包裹一层血运丰富和生骨能力极强的骨外膜，而在骨膜外还有丰富的肌肉附着，因此结核杆菌较少侵及骨干形成结核病灶，故骨干结核临床病例较少。我所4826例骨关节结核中骨干结核仅81例，占1．7％。骨干结核可分为长骨骨干结 The backbone of the middle of the tubular bone, composed of hard bone cilia. Due to the backbone surrounded by a layer of rich blood supply and strong ability of bone formation of the adventitia, but also in the periosteum, there are a wealth of muscle attachment, so Mycobacterium tuberculosis less invasion and the formation of tuberculosis, so less clinical cases of bone tuberculosis . In our 4826 cases of osteoarticular tuberculosis in the backbone of the tuberculosis only 81 cases, accounting for 1.7%. Backbone tuberculosis can be divided into long bone backbone
