Abstract

From January, 1984 to January, 1985 twelve patients with unstable fracture and fracture-dislocation of the thoraco . lumbar spine with neurologic deficits were treated with Harrington Instrument. Fixation by Harrington Instrumentation appeared to provide stabilization, reduction and return of neural function. Author performed Harrington Instrumentation with experience of 12 cases of unstable thoraco . lumbar spine fructure and fracture-dislocation with neurologic deficits. Results were as follows : 1) Spinal fracture and fracture-dislocation were most common in thoraco . lumbar Junction. 2) Harrington Instrumentation was very effective for keeping the spine stability in unstable fracture. 3) Six cases (50%) had a complete neurologic deficit and six cases (50%) had a incomplete neurologic deficit, two cases of the six patients with complete neurologic deficits recovered slightly but two cases with incomplete neurological deficit gained complete recovery. 4) During the postoperative period, early ambulation was possible and average admission period were 71 days. 5) Correction of spinal deformity. A. Average value of kyphotic angle (12.5 degrees). B. Average value of Iw(Index of weding) (1.32). C. Displacement was completely corrected in eight patients (100%).
