Bisphosphonates are compounds characterized by a P-C-P structure. They act essentially on bone, inhibiting bone resorption. Through this mechanism they decrease bone loss, increase bone mineral density, and decrease bone turnover. ⋯ In the latter they diminish both vertebral and nonvertebral fractures. The adverse events are few, mostly gastrointestinal, and can be avoided to a large extent by correct administration. Since there are no other compounds available which have a similar profile, they represent today the drugs of choice in the treatment and the secondary prevention of osteoporosis.

Cervical spondylotic myelopathy is a clinical entity that manifests itself due to compression and ischemia of the spinal cord. The goal of treatment is to decompress the spinal cord and stabilize the spine in neutral, anatomical position. Since the obstruction and compression of the cord are localized in front of the cord, it is obvious that an anterior surgical approach is the preferred one. The different surgical procedures, complications, and outcome are discussed here.

Bony metastases are a frequent problem in elderly patients affected by cancer, and those with bony metastases involve the spine in approx. 50%. The most frequent spinal metastases (60%) are from breast, lung, or prostate cancer. The chance that an elderly patient (60-79 years old) is affected by bony metastases is four times higher in men and three times higher in women than a middle-aged patient (40-59 years old). ⋯ Surgical management shows the greatest improvement in pain reduction, but also in other domains of quality of life. Since prospective randomized studies comparing different treatment modalities for spinal metastases including surgery are not available and are ethically difficult to achieve, each case remains an interdisciplinary, shared decision making process for what is considered best for a patient or elderly patient. However, whenever surgery is an option, it should be planned before irradiation since surgery after irradiation has a significant higher complication rate.

There is a relatively high prevalence of osteoporotic vertebral compression fractures (VCFs) in the elderly population, especially in women aged 50 or older. The result of these VCFs is increased morbidity and mortality in the short and long term. Medical treatment of these fractures includes bed rest, orthotics, analgesic medication and time. ⋯ Research continues into the development of injectable biomaterials that are resorbable and allow for new bone formation. Vertebroplasty and kyphoplasty are safe and effective in the treatment of osteoporotic VCFs. They may allow for a faster return to function, and thus avoid the morbidity associated with medical treatment.

Review Multicenter Study Guideline
Classification and management of early complications in open lumbar microdiscectomy.
Complications and side effects in any kind of surgery, especially in spine surgery, should be evaluated to prevent those problems in the future. Since retrospective studies are of minor value and randomized controlled studies for complications are impossible to perform because of ethical and legal reasons, so-called "expert opinion" has to take their place in evidence-based medicine. On the basis of an analysis of the results of three spine centers together with the opinions of experienced spine surgeons, the authors have drawn up a classification of complications in open lumbar disc surgery and recommendations on how to manage common complications such as excessive bleeding, dural opening, nerve root lesions and recurrent disc herniation. The management of intraoperative complications should have the same training in microdiscectomy instructional courses as the operation itself.
