“…The fusion rate of 23 out of 36 patients reported in this review compares favourably with the results reported for anterior interbody fusion (Flynn & Hoque 1979, Frymoyer 1978, Freebody et al 1971, but less favourably with the results of intertransverse fusion (Rombold 1976, Stauffer & Coventry 1972.…”

“…Reported fusion rates have varied widely in patients with anterior interbody fusions without posterior fixation as exemplified by those of Harmon, 95% [15]; Hoover, 70% [17]; Fujimaki et al 96% [13]; Stauffer and Coventry, 56% [30]; Flynn and Hoque, 56% [10]; and Calandruccio and Benton 19% [4]. However, these studies used non-comparable types of graft procedures and patient populations.…”

This is a radiographic report of 40 patients (20 men, 20 women) who underwent anterior lumbar interbody fusions (73 levels) utilizing a "hybrid" interbody graft composed of femoral cortical allograft (FCA) bone and iliac crest cancellous autograft bone. The average age at surgery was 38 years (range 17-64 years), and follow-up averaged 1.4 years (range 1.0-2.4 years). Nineteen of the patients had undergone previous lumbar surgery. Thirty-two patients (63 levels) underwent anterior fusion combined with some type of posterior fixation, and eight patients (10 levels) had no posterior fixation. Types of posterior fixation included: for 20 patients (36 levels) Steffee variable screw placement fixation, for 10 patients (23 levels) translaminar facet screws (TFS), for 1 patient (3 levels) Knodt rods and for 1 patient (1 level) facet screws. Based on the persistence of lucent lines at the graft-host interface, three patients (one level each) were felt to have non-unions at their latest follow-ups at 1.4, 1.5 and 2.0 years, respectively. Two of these patients had no posterior fixation, and the other had TFS fixation. The overall fusion rate was 96% (70 of 73 levels). The fusion rate for all levels treated with posterior fixation was 98% compared with 75% for those without fixation. Intervertebral disc heights (IVDH) were measured on all films and corrected for magnification with computer assistance. On average, the IVDH was increased postoperatively but returned to preoperative values at follow-up. IVDH loss was independent of the type of instrumentation used. No complications arose from the use of the hybrid graft.(ABSTRACT TRUNCATED AT 250 WORDS)

“…Reviews of repeat fusion for failed surgery in the lumbar spine show a 50-65% fusion rate and a clinical failure rate as high as 40-70% in patients with symptomatic lumbar pseudarthrosis 11,16,33,35 . Although some authors have contended that a pseudarthrosis after an attempted arthrodesis cannot automatically be assumed to be the principal cause of continuing symptoms and that operative repair is therefore not always mandatory 8,32 , it is our experience, as well as that of others 14,16,20,30 , that a pseudarthrosis after an attempted arthrodesis in the lumbar spine does result in continuing pain and impairment and that patients may be helped by successful pseudarthrosis repair 15,14,20 .…”
