Flesch et al evaluated 40 patients with unstable thoracolumbar fractures, with 34 of these injuries being rotatory fracturedislocations, with the remaining fractures being burst or compression injuries that subsequently became unstable following laminectomy. All 40 patients underwent Harrington rod instrumentation and fusion, and a subset of these patients also underwent laminectomy for decompression. Instrumentation and fusion were performed on average 46 days following injury (range of 7 days to 11 months). At follow-up all patients had a stable spine without evidence of deformity and with one exception all had a solid fusion. Although there was no neurological improvement in the cases with complete deficit 406 at presentation (n 12), 90% of the patients with incomplete cord or cauda equina lesions regained some neural function. Based on historical comparisons, the authors argued that Harrington instrumentation also produced earlier mobilization, rehabilitation, and hospital discharge. Dickson et al evaluated 95 patients, all with thoracolumbar fracture-dislocations, who were treated with open reduction and stabilization with Harrington instrumentation and fusion. The authors reported earlier mobilization and rehabilitation but noted that the recovery rate was no better than prior reports that relied on postural reduction and prolonged bed rest.
