Spinal fusion: A surgical procedure in which two or more of the vertebrae in the spine are united together so that motion no longer occurs between them. Spinal fusion may be done to treat a number of conditions, including scoliosis, deformity, fracture, and disc disease. Bone grafts are usually placed around the section of the spine to be fused. The body then heals the grafts over several months, which joins the vertebrae together. The bone for the graft may be taken from another bone in the patient (autograft) or from a bone bank (allograft).

May sees temperatures rising by around 3 degrees on the south coast of Spain and around 4 degrees in central areas. Temperatures on the north coast are now being held back by the cooling effect of the Atlantic Ocean, rising just over 2 degrees on the previous month, with Madrid now significantly warmer than La Coruna.id-winter, and in most cases, the coldest month of the year. The Canary Islands are of course still quite mild and coastal areas of mainland Spain are not doing too badly but there is a cold band inland across the north of the country which is colder than London, with Soria only averaging 2.0 o C.
