ABSTRACT

Research paper thumbnail of Neurological complications of ankylosing spondylitis

Journal of Neurosurgery, 1993

✓ Thirty-three patients with ankylosing spondylitis with or without spinal neurological symptoms ... more ✓ Thirty-three patients with ankylosing spondylitis with or without spinal neurological symptoms requiring surgical intervention were identified in a retrospective review of all cases of spinal disorders treated at the Mayo Clinic during the period from 1984 to 1989. Spinal fractures (traumatic or pseudoarthroses), progressive spinal deformity, rotary instability secondary to atlanto-occipital or atlantoaxial subluxation, and spinal stenosis with associated neurological deficit, pain, or spinal instability were the most common indications for surgery. Of the 41 operations performed, there were 17 cervical, 14 thoracic, and 10 lumbar procedures. Eight patients had two or more disorders at separate spinal levels that required surgery. Preoperative neurological deficits were recorded in 13 patients: these improved following surgery in nine and stabilized in four. This review emphasizes the fragility of the ankylosed spinal column and its inherent susceptibility to fracture with attenda...

All hips had Paprosky scores of III or IV. Harris hip scores improved from 43 to 82. There was 1 intraoperative and 2 postoperative fractures. A single stem was revised during the study. Radiographic review showed the 40 unrevised stems to be stable, and graft incorporation was seen in at least 1 zone in 100% of the femurs. There was no stem subsidence greater than 2.5 mm. The results of this study demonstrate that preoperative planning and a surgical technique, which emphasizes femoral support and vigorous impaction grafting, resulted in an acceptable incidence of complications.

Computer-assisted navigation systems may reduce positional errors. Total hip arthroplasty results were analyzed using an imageless navigation system. We hypothesized that reliability and accuracy would improve. One hundred forty-nine total hip arthroplasties were performed using minimally invasive surgical techniques in 3 cohorts: manual (n = 53), initial navigation cases (n = 49), navigation second series (n = 47). Manual patients' cup orientation variation from desired range was −19°to +18°anteversion (SD, 9.1°), −11°to +25°abduction (SD, 6.7°). Navigation variation from desired was −18°to +15°(SD, 7.3°) in group 1 and −15°to +9°(SD, 5.9°) in group 2 in anteversion and −15°to +13°(SD, 6.1°) in group 1 and −15°t o +11°(SD, 4.7°) in group 2 in abduction. Results were statistically significant. There were significant differences for operating room time and estimated blood loss, but not incision size or body mass index. Navigation provided controlled, reproducible acetabular alignment; but a learning curve existed in terms of accuracy, estimated blood loss, and operating room time.
