| Popis: | From 1986 to 1990 50 patients with increasing spinal instability due to pathologic fractures of one or more vertebrae were operated in the Orthopedic Department of Mainz University Hospital. In the course of 57 operations anterior decompression and stabilization were performed 3 times, whereas dorsal spondylodesis was done with Cotrel-Dubousset's instrumentation (CDI) 32 times, with Luque's 7 times and with Harrington's 1 time; a combination of CDI and Luque was chosen in 2 cases, a combination of Harrington and Luque in 1 case. 3 times a single-stage combination and 4 times a two-stage combination of ventral and dorsal stabilization was used. The application of the CDI required no postoperative external support. 35 patients suffered from major neurologic deficits preoperatively--among them 11 from a complete and 6 from an incomplete paraparesis--which made spinal cord decompression necessary in advance of the dorsal stabilization. Of these, 16 improved significantly; however, deterioration of the neurologic status occurred in 4 cases with a paraparesis in 3 of them. Survival time postoperatively was approximately 13 months in 27 patients. 9 of these died within half a year after the operative intervention. Failure of fixation as a result of tumor lesion was found in 2 cases of CDI procedure and in 1 case of the Harrington instrumentation. All required a revisional operation. 3 patients developed a radiologic lysis of methylmethacrylate implants fixed by an anterior procedure. Posterior decompression and stabilization render possible resolution of spine pain as well as restoration of mobility until a few days before exitus letalis without restricting adjuvant radio- or chemotherapy.(ABSTRACT TRUNCATED AT 250 WORDS) |
