Clinical Experiences of Spinal Surgery using TSRH Instrument / 대한정형외과학회잡지

The main goal of spinal surgery using implant is a rigid fixation to provide the stability until solid fusion will occur. Recently, various implant fixation devices have been introduced and transpedicular screw fixation is the usual method. In the past, we obtained the implant-related complications like screw failure and rod breakage after using the modified Harrington rod. However, we obtained good results after follow up over one year using TSRH instrument. We experienced spinal surgery using TSRH instrument in 42 cases since 1991 and followed from one year to 28 months with average 16 months. We analyzed the 28 cases and evaluated the implant-related problems. The results were as follows: 1. Among 28 patients, 10 patients were operated due to fracture and 9 patients operated due to spinal stenosis. 2. The male patients were 16 cases and the female were 12 cases. 3. The TSRH instruments provided the rigid fixation with three points clamping mechanism. 4. The cross-linking plate of TSRH was found to increase stiffness and strength. 5. There were no case of screw breakage. 6. In functional results by Kirkaldy-Willis; foriteria the excellent cases were 15, and the good were 2 cases.

Application of TSRH Instrumentation In Degenerative Lumbar Surgery

The patients with degenerative lumbar spine disease were treated using TSRH(Texas Scottish Rite Hospital) universal instrumentation system. The patient population consisted of 6 men and 4 women with a mean age of 56 years(43 to 65 years). All patients suffered chronic back pain with other neurological symptoms and signs. Neurological improvement was obtained in all cases postoperatively. Complication include pneumonia in 1 case, deep vein thrombosis in 1 case, flaccid neurogenic bladder in 1 case. Autogenous bone graft, obtained from iliac bone, between transverse process provided excellent bony fusion in 7 cases on radiologic evaluation between 9 months to 12 months after operation. TSRH universal instrumentation system have several advantages compared with other pedicle screw rod systems ; easy to handle, low morbidity, shorter operative time and easier relieval of root compression.
