Object The authors conducted a prospective longitudinal study to assess the efficacy of ProDisc arthroplasty in patients in whom symptomatic adjacent-segment degeneration has developed after remote lumbar fusion. The follow-up period was a minimum of 2 years. Methods The 20 patients in this study ranged in age from 18 to 67 years. They presented with disabling adjacent-level discogenic low-back pain with or without L1–S1 radicular pain. Patients with radiographic evidence of circumferential spinal stenosis or facet joint degeneration had been excluded. Patients were assessed preoperatively and postoperatively at 3, 6, 12, and 24 months. Eighteen patients (90%) fulfilled all follow-up criteria. The median age of all patients was 50 years. Statistical improvements in visual analog scale, Oswestry Disability Index, and patient satisfaction scores were documented 3 months after arthroplasty. These improvements remained at the 24-month follow-up examinations. Patient satisfaction rates were 86% at 24 months. Radicular pain was also significantly decreased. No additional surgeries were necessary at affected or unaffected levels. Conclusions Analysis of early results indicates that ProDisc lumbar total disc arthroplasty is an efficacious treatment for symptomatic adjacent-segment lumbar discogenic low-back pain following remote fusion. Significant improvements in patient satisfaction and disability scores were observed by 3 months postoperatively and were maintained at the 2-year follow-up examination. No device-related complications occurred. Patients should be screened carefully for evidence of facet joint impingement/degeneration, hardware-induced pain, and/or nonunion at prior fusion levels before undergoing disc replacement surgery.

Object During the past decades, lumbar fusion has increasingly become a standard treatment for degenerative spinal disorders. However, it has also been associated with an increased incidence of adjacent-segment degeneration (ASD). Previous studies have reported less ASD in anterior fusion surgeries; thus, the authors hypothesized that the integrity of the posterior complex plays an important role in ASD. This study was designed to investigate the effect of the posterior complex on adjacent instability after lumbar instrumentation and the development of ASD. Methods To evaluate different surgical interventions, 120 patients were randomly allocated into 3 groups of 40 patients each who were statistically similar with respect to demographic and clinical data. Patients in Group A were allocated for facet joint resection and L4–5 fusion, Group B for semilaminectomy and fusion, and Group C for complete laminectomy and fusion. All of the patients were followed up for 5–7 years (mean 5.9 years). The disc height, intervertebral disc angle, dynamic intervertebral angular range of motion (ROM), L3–4 slip, and the total lordosis angle were each measured before the operation and at the final follow-up. The Japanese Orthopaedic Association (JOA) score was determined before surgery and at the final follow-up to evaluate the clinical results. Results Among the 3 groups, no significant differences were detected in all clinical and demographic assessments before surgery. At 3 months after surgery, the JOA score of all groups improved significantly and showed no significant differences among the groups. At the final follow-up, Group C had a significantly (p < 0.05) lower JOA score than the other 2 groups. Moreover, the disc height and total lumbar lordosis in patients of Group C were significantly decreased compared with disc height and total lumbar lordosis in the other 2 groups. In contrast, disc angle, dynamic angular ROM, and listhesis were significantly higher in Group C than in the other 2 groups. Twenty-four patients showed signs of ASD after the operation (3 patients in Group A, 4 in B, and 17 in C). The number of patients in Group C showing ASD was significantly different from that in Groups A and B. Conclusions During follow-up for 6 years, a significantly higher number of patients with ASD were noted in the complete-laminectomy group. The number of reoperations for treating ASD was much higher in this patient group than in the patients undergoing facet joint resection and L4–5 fusion or semilaminectomy and fusion. Therefore, preserving the posterior complex as much as possible during surgery plays an important role in preventing ASD and in reducing the reoperation rate.

Object. The authors examined the effect of psychological and emotional status on the outcome in patients with suspected chronic discogenic low-back pain (LBP) who have undergone lumbar fusion. Methods. The authors retrospectively analyzed the medical records, including the results of the 36-item Short Form (SF-36), of 57 consecutive patients (mean age 42.7 years) who underwent single-level lumbar reconstructive surgery between 1994 and 2000. The SF-36 physical component summary (PCS) and mental component summary (MCS) domains were evaluated. Data were sorted into the following categories: excellent, good, fair, same, and worse. Scores greater than 40 for MCS and PCS were defined as “normal” according to US general population data provided by the Medical Outcomes Trust. Of 57 patients, 47 completed postoperative SF-36 surveys at 1 year and 36 completed the 2-year follow-up surveys. Analysis showed that preoperative MCS scores exhibited a significant, direct correlation with PCS score improvements at 1 (r = 0.584, p = 0.000) and 2 (r = 0.623, p = 0.000) years after surgery. In patients in whom preoperative MCS scores reflected normal status, outcomes were excellent or good in 60% at 1-year (18 of 30 cases) and 2-year (15 of 25 cases) follow-up intervals. Patients in whom MCS scores represented abnormal status had less satisfactory outcomes, with excellent or good outcome in only two (18.2%) of all patients at the 2-year follow-up study. Conclusions. Analysis of the data suggests that psychological and emotional distress may negatively affect postoperative outcome in patients with chronic discogenic LBP. The SF-36 may be easily and effectively used to measure both preoperative psychosocial distress and postoperative outcome.

Abstract Background We investigated whether spinopelvic parameters are important prognostic factors causing adjacent segment degeneration (ASD) after long instrumented spinal fusion for degenerative spinal disease. Methods This uncontrolled, randomized, single arm retrospective study included patients who underwent long instrumented lumbar fusion (fusion levels≥ 4) in the past 5 years with follow-up for at least 2 years. The inclusion criteria included adult patients (≥40 years of age) with a diagnosis of spinal degeneration who underwent instrumented corrective surgery. The exclusion criteria included preexisting adjacent disc degeneration, combined anterior reconstructive surgery, and distal ASD. Clinical and operative characters were evaluated. Angle of lumbar lordosis (LLA), sacral slope (SSA), pelvic tilt (PTA) and pelvic incidence (PIA) were compared preoperatively, postoperatively and at the final follow-up. Results From 2009 to 2014, 60 patients (30 ASD and 30 non-ASD) were enrolled. The average age was 66.82 ± 7.48 years for the study group and 67.97 ± 7.81 years for the control group. There was no statistically significant difference in clinical and operative characteristics. Among all spinopelvic parameters, only pre-, post-operative and final follow-up PIA in ASD group (53.9±10.4ﾟ, 54.6±14.0ﾟ, 54.3±14.1ﾟ) and non-ASD group (60.3±13.0ﾟ, 61.8±11.3ﾟ, 62.5±11.2ﾟ) showed statistically significant differences ( p <0.05). Conclusion This study confirms that preoperative, postoperative and final follow-up PIA is a significant factor contributing to the development of ASD after long instrumented spinal fusion.

Abstract Background Symptomatic adjacent-segment degeneration (ASD) is a common complication after lumbar fusion surgery. We want to evaluate the clinical and imaging outcome of full-endoscopic lumbar decompression (FELD) in comparison with extended posterior lumbar interbody fusion (PLIF) for ASD after lumbar fusion surgeries and develop a staged revision strategy. Methods This retrospective study enrolled 65 patients with ASD who treated with FELD (n=31) or extended PLIF (n=34) between January 2014 and January 2018. Clinical outcome evaluations were performed preoperatively, at 3, 12, 24 months postoperatively, including Oswestry Disability Index (ODI) score and Japanese Orthopaedic Association (JOA) scores for function assessment, visual analog scale (VAS) scores for low-back pain and leg pain. Imaging outcome evaluations were performed preoperatively, immediately after surgery and at the last follow up, including disc height (DH) and lumbar lordosis (LL). Results The ratio of patients with adjacent segmental instability in the PLIF group was significantly higher than that in the FELD group (p<0.05). There was no significant difference in other baseline data for FELD and PLIF groups (p>0.05). Mean operative time, blood loss and length of hospital stay were significantly decreased for the FELD group (p<0.001). For patients with stable adjacent segments, there was no significant difference in preoperative and postoperative low-back pain, leg pain and function between 2 groups (p>0.05). The patients in PLIF group had restored DH after surgery, which was significantly higher than FELD group (p<0.05). For patients with unstable adjacent segments, the low-back and leg pain of PLIF group were significantly relieved than that in FELD group within 24 and 3 months after surgery (p<0.05). The function of PLIF group was significantly improved within 12 months after surgery (p<0.05). The DH was only significantly restored within 3 months after surgery (p<0.05). Recurrence was found in 2 (6.5%, p>0.05) patients in FELD group, while no patient in PLIF group had recurrence. Conclusions FELD could achieve satisfactory safety and efficacy for the treatment of stable ASD, which was not worse than PLIF. With less trauma and faster recovery, FELD may be an alternative surgical treatment for stable ASD.
