Surgical management of symptomatic spinal metastases, in particular anterior decompression, is of benefit in most metastatic lesions in terms of satisfactory postoperative outcome and quality of life. However, in patients with melanoma or lung carcinoma, the authors advocate spinal surgery only in very exceptional cases.

Tendons connect muscles to bones, ensuring joint movement. With advanced age, tendons become more prone to degeneration followed by injuries. Tendon repair often requires lengthy periods of rehabilitation, especially in elderly patients. Existing medical and surgical treatments often fail to regain full tendon function.The development of novel treatment methods has been hampered due to limited understanding of basic tendon biology. Recently, it was discovered that tendons, similar to other mesenchymal tissues, contain tendon stem/progenitor cells (TSPCs) which possess the common stem cell properties.The current strategies for enhancing tendon repair consist mainly of applying stem cells, growth factors, natural and artificial biomaterials alone or in combination. In this review, we summarise the basic biology of tendon tissues and provide an update on the latest repair proposals for tendon tears.Cite this article: EFORT Open Rev 2017;2:332-342.
