Embolization of spinal metastases reduces peroperative blood loss : 21 patients operated on for renal cell carcinoma
(1993) Olerud, Claes; Jónsson, Halldór; Löfberg, Ann Marie; Lörelius, Lars Erik; Sjöström, Lennart; Department of Engineering
We evaluated the peroperative blood loss in 21 patients who were treated with 29 operative procedures for thoracolumbar spinal renal cell carcinoma metastases. Embolization was undertaken prior to 11 operations. At posterior surgery the average blood loss was one third after embolization compared with when embolization had not been performed. the blood loss was also lower during anterior surgery, although this difference was smaller. We recommend that preoperative embolization should precede surgical treatment of spinal metastases of renal cell carcinoma where it can be anticipated that the operation will extend into the pathological tissue.

Surgery for multiple myeloma of the spine : A retrospective analysis of 12 patients
(1992) Jonsson, Bogi; Sjöström, Lennart; Jónsson, Halldór; Karlström, Göran; Department of Engineering
We report on 12 surgically treated patients with myeloma of the spine. Pain relief was obtained in all the patients. Paraparesis was present in 5 patients. All 12 patients subsequently became ambulatory. the average postoperative survival was 2.3 years. Eight patients, all without symptoms from the treated lesion, survived for more than 1 year. Our experience suggests that surgical treatment of multiple myeloma of the spine may be rewarding.

Posterior reduction of a pathologic spinal fracture a case of indirect anterior Dural decompression
(1992) Olerud, Claes; Sjöström, Lennart; Jónsson, Halldór; Karlström, Göran; Department of Engineering
In a patient with paraparesis resulting from a pathologic fracture of Th9, which was due to a breast cancer metastasis, indirect anterior decompression via posterior reduction was performed. the rationale for the operation technique was the similarity between a pathologic fracture of the thoracolumbar spine and a traumatic burst fracture. the method, which uses a transpedicular reduction and fixation device, is substantially less invasive than a formal anterior decompression.

Compression of the cervical spine cord after reduction of fracture dislocations : Report of 2 cases
(1991) Olerud, Claes; Jónsson, Halldór; Department of Engineering
Two cases of severe neurologic damage after open reduction of locked facet joint dislocations of the cervical spine are described. Both patients had progressive neurologic deterioration after the accident. In both cases, the cause of the neurologic injury was sequestrated disk material compressing the spinal cord. One patient, who was reoperated on as an emergency, recovered after removal of the sequestra, whereas the other patient, who was reoperated on later, remained tetraplegic.

Anterior stabilization of pathologic dens fractures
(1990) Sjöström, Lennart; Olerud, Sven; Karlström, Göran; Hamberg, Mats; Jonsson, Halldor; Department of Engineering
By an anterior approach, six pathologic dens fractures were stabilized with screws and methyl methacrylate cement. All the patients had immediate pain relief and could be mobilized without external support. Using the anterior approach, the tumor can be removed and the instability neutralized at the site of the lesion.
