Osteoporotic vertebral compression fractures are a commonly encountered clinical problem. Although the majority of patients with this injury experience a benign and self-limited course of gradually resolving pain, a significant number continue to experience chronic pain and disability. In evaluating a patient with a vertebral compression fracture, the differential diagnosis must consider not only osteoporosis, but also various causes of osteomalacia, endocrinopathy, and malignancy. Accumulation of multiple compression fractures and increased thoracolumbar kyphosis are associated with a poor prognosis. Multiple medical treatments--including hormone replacement therapy, calcitonin, and bisphosphonates--are effective in maintaining or increasing bone mass and reducing the risk of compression fracture. Conventional treatment in the form of pain medication, activity limitation, and occasionally bracing is effective in returning most patients to their previous level of functioning. When therapies fail, patients may be considered for minimally invasive treatments such as vertebroplasty or kyphoplasty. Surgery, although enormously challenging because of poor underlying health status and structurally weak bone, may be the last resort for a small percentage of patients experiencing progressive deformity or neurologic deficit.
骨质疏松性椎体压缩骨折是临床常见问题。虽然大多数此类损伤患者经历良性且自限性病程,疼痛会逐渐缓解,但仍有相当一部分患者持续遭受慢性疼痛和功能障碍。在评估椎体压缩骨折患者时,鉴别诊断不仅要考虑骨质疏松,还要考虑骨软化、内分泌病及恶性肿瘤的各种病因。多个压缩骨折的累积以及胸腰段后凸增加与预后不良相关。多种医学治疗方法,包括激素替代疗法、降钙素和双膦酸盐,在维持或增加骨量以及降低压缩骨折风险方面有效。以止痛药物、限制活动以及偶尔使用支具等形式的传统治疗,能使大多数患者恢复到先前的功能水平。当治疗失败时,可考虑对患者进行诸如椎体成形术或后凸成形术等微创治疗。手术尽管因基础健康状况差和骨质结构薄弱而极具挑战性,但对于一小部分出现进行性畸形或神经功能缺损的患者可能是最后的手段。
