Abstract:
For the evaluation of the clinical and radiologicaI result in the surgical reduction and internal stabilization of the fracture-dislocations in the thoracic and lumbar area, the authors analysed the 39 patients who were treated with Harrington instrumentation supplemented by segmental sublaminar wiring and were follow up 24 months in average. l. Indications for the operation were: compression type with more than 50% of body wedging, bursting type with less than 30% of canal involvement without cord injury, fracture-dislocation type with instability and any type with complete cord injury. 2. Amount of fusion were 6 segments in 25 cases, 7 segments in 11 cases, 5, 8 and 10 segments in 1 case each. 3. Among 31 cases whose lumbar segment were involved in fusion, numbers of movable lumbar motion segments were three or less in 26 and two or less in 8. 4. Angular deformity were changed from 27 preoperatively to 8 postoperatively and to 12 at the end of follow up. Wedging amount of anterior vertebral height were 53% preoperatively, 23% postoperatively and 27% at the end of follow up. 5. External support were applied for 4 months in 35 cases; Taylor brace in 22, TLSO in 10 and body cast in 3. Ambulation was started within a week according to the general status. 6. Solid bony union were observed in 38 cases within 4 months period. Dislodgement of instrumentation and deep infection in one each patient were observed as operative complications. 7. Among 21 cases with cord injury symptoms, 18 cases with complete type showed no neurological recovery, but 3 cases with incomplete type showed complete recovery. It is concluded that the Harrington instrumentation with sublaminar wiring is an effective method of reduction and stabilization for the fracture and dislocations of the thoracic and lumbar spine. On the other hand, the operation is an extensive procedure with significant involvement of lumbar motion segments.
