Abstract Background Minimally invasive, thoracoscopic anterior spondylodesis (MIAS) is an established treatment for burst fractures of the thoracolumbar spine. Good restoration of the local sagittal alignment and good functional results have been reported. The aim of this study was to evaluate long-term results of MIAS in patients with incomplete burst fractures and to analyze the influence on global sagittal alignment, clinical outcomes, and adjacent segment degeneration. Methods From 2002 to 2003, 18 patients were treated with MIAS for incomplete thoracolumbar burst fractures. Mono-segmental spondylodesis was performed with an iliac crest bone graft and bisegmental spondylodesis with a titanium cage. In this single-center prospective cohort study, 15 patients were available for follow-up (FU) after an average of 12.9 years (12.1–14.4). Seven patients were treated with a combined anterior and posterior instrumentation and eight patients with anterior spondylodesis only. The primary clinical outcome parameter was the Oswestry Disability Index (ODI); secondary parameters were the Short Form 36 (SF36) and the visual analog scale (VAS spine). Full spine radiographs were assessed for bisegmental Cobb angle, alignment parameters, and signs of adjacent segment degeneration (ASD). Results ODI evaluation showed a mean impairment of 11.7% with minimal limitations in 13 patients. Neither a significant deterioration over time nor significant differences between both therapy strategies were found in the clinical scores at the latest follow-up. The mean bisegmental increase of regional malalignment of reduction was 8.8° (± 7.3°) with no significant correlation to any clinical outcome scores. The majority of patients had no signs of adjacent segment degeneration. Two patients showed minor radiologic changes. All patients had a balanced sagittal spine profile. Conclusions In conclusion, MIAS leads to good clinical results with—in majority—minimal spine-related impairment at the latest follow-up. No significant deterioration at 12-year FU was detectable compared to the 6-year results for the SF36 and VAS spine scores. There was no association between sagittal alignment, clinical outcome scores, and ASD. Trial registration The study was retrospectively registered in the German Clinical Trials Register (Nr.00015656).

Object A systematic review concerning surgical management of lumbar degenerative spondylolisthesis (DS) showed that a satisfactory clinical outcome was significantly more likely with adjunctive spinal fusion than with decompression alone. However, the role of adjunctive fusion and the optimal type of fusion remain controversial. Therefore, operative management for multilevel DS raises more complicated issues. The purpose of this retrospective study was to elucidate clinical and radiological outcomes after 2-level PLIF for 2-level DS with the least bias in determination of operative procedure. Methods Since 2005, all patients surgically treated for lumbar DS at the authors' hospital have been treated using posterior lumbar interbody fusion (PLIF) with pedicle screws, irrespective of severity of slippage, patient age, or bone quality. The authors conducted a retrospective review of 20 consecutive cases involving patients who underwent 2-level PLIF for 2-level DS and had been followed up for 2 years or longer (2-level PLIF group). They also analyzed data from 92 consecutive cases involving patients who underwent single-level PLIF for single-level DS during the same time period and had been followed for at least 2 years (1-level PLIF group). This second group served as a control. Clinical status was assessed using the Japanese Orthopaedic Association (JOA) score. Fusion status and sagittal alignment of the lumbar spine were assessed by comparing serial plain radiographs. Surgery-related complications and the need for additional surgery were evaluated. Results The mean JOA score improved significantly from 12.8 points before surgery to 20.4 points at the latest follow-up in the 2-level PLIF group (mean recovery rate 51.8%), and from 14.2 points preoperatively to 22.5 points at the latest follow-up in the single-level PLIF group (mean recovery rate 55.3%). At the final follow-up, 95.0% of patients in the 2-level PLIF group and 96.7% of those in the 1-level PLIF group had achieved solid spinal fusion, and the mean sagittal alignment of the lumbar spine was more lordotic than before surgery in both groups. Early surgery-related complications, including transient neurological complications, occurred in 6 patients in the 2-level PLIF group (30.0%) and 11 patients in the 1-level PLIF group (12.0%). Symptomatic adjacent-segment disease was found in 4 patients in the 2-level PLIF group (20.0%) and 10 patients in the 1-level PLIF group (10.9%). Conclusions The clinical outcome of 2-level PLIF for 2-level lumbar DS was satisfactory, although surgery-related complications including symptomatic adjacent-segment disease were not negligible.

Background: The value of drug-eluting stents in patients (P) with in-stent restenosis (ISR) has been established. However, the long-term results of this strategy in P with ISR remains unknown. Objective: We sought to determine the long-term clinical outcome of P treated with sirolimus-eluting stents (SES) for ISR. Methods: A systematic, pre-specified, long-term clinical follow-up (FU) was performed in all P included in the RIBS II (Restenosis Intra-stent: Balloon angioplasty [BA] vs elective SES implantation) randomized trial. In RIBS II 150 P with ISR after bare-metal stent implantation were included: 74 allocated to BA and 76 to SES. Late angiography was obtained in 96% of eligible P. A structured clinical questionnaire (cardiac/non cardiac death, myocardial infarction [MI], target vessel revascularization [TVR], thrombosis [TH], and medical therapy) was used during FU. Results: Angiographic restenosis (primary end-point) was more frequently found in the BA arm (39% vs 11%, p<0.001). Clinical FU at 1-year was obtained in 150 P (100%). During this time period 6 P died (3 SES, 3 BA), 4 P suffered a MI (2 SES, 2 BA), 2 P experienced TH (1 P in each arm) and 30 required TVR (8 SES, 22 BA, p<0.01). A complete clinical FU >3 years was obtained in 145 P (97%) (mean 38±9 months, median 40 months [IQR 37–42]). Late events (after 1 year, non-exclusive) included: 3 deaths (1 SES, 2 BA), 3 MI (3 SES, 2 due to late TH) and 7 late TVR (5 SES, 2 BA). At 4 years, event-free survival was 76% in the SES arm and 65% in the BA arm (p=0.03). Survival free from TVR at 4 years was 80% in the SES arm and 67% in the BA arm (p=0.02). Conclusion: In P with ISR SES implantation improve the long-term clinical outcome as compared with BA treatment.

Purpose: Presently, there is no publication combining clinical follow-up with magnetic resonance imaging (MRI) to determine possible post-traumatic alterations following paediatric intra-articular fractures of the medial malleolus. Therefore, the aims of this study were to retrospectively analyze a cohort of patients with Salter–Harris (SH) III and IV fractures of the medial malleolus and to evaluate their long-term outcome. MRI was used to assess possible changes of the articular surface that cannot be diagnosed on native radiographs. Patients and Methods: Fifty-four patients with SH III ( n = 38) or IV fractures ( n = 17) of the medial malleolus treated between 2001 and 2011 were invited for a follow-up examination. Clinical outcome was assessed with the Weber score and osteoarthritis with the Kellgren and Lawrence classification. MRI was rated by the Outerbridge classification. Correlations between the clinical and radiological outcomes were calculated. Results: Seventeen patients were recruited for long-term follow-up at a mean of 112 (range, 65–184) months. The Weber score was very good for 5 patients, good for 10 patients and poor for 2 patients; the Kellgren and Lawrence score revealed a favourable grade 0 in 15 patients and grade 1 in 2 patients. The MRI-based Outerbridge classification yielded grade 0 for 12 patients, grade 1 for 1 patient, grade 2 for 2 patients and grade 3 for 1 patient. The Outerbridge score significantly ( p < 0.05) correlated with the Weber score. Conclusion: This study shows excellent and good outcome of SH III and IV fractures of the medial malleolus. Worse clinical outcome correlated with post-traumatic changes of the articular cartilage seen on MRI.

Abstract BACKGROUND: Although favorable clinical outcomes have been reported for instrumented lumbar interbody fusion (LIF), adjacent segment degeneration (ASD) has been reported as a long-term complication after LIF. OBJECTIVE: To investigate ASD after instrumented LIF performed at a single level and only for the homogeneous disease of adult low-grade isthmic spondylolisthesis. METHODS: A total of 128 patients who had undergone LIF for the treatment of adult low-grade isthmic spondylolisthesis involving the lower lumbar spine at our institution between February 2001 and December 2004 were retrospectively reviewed by chart review and telephone survey. Of them, 103 patients with a minimum of a 36-month follow-up period were enrolled in this study. The mean age was 48.5 years. The average follow-up period was 59 months. Clinical and radiological data related to segmental lordosis (SL), whole lumbar lordosis, sacral slope, pelvic tilt, pelvic incidence, and L1 axis S1 distance were analyzed to identify significant risk factors for ASD. RESULTS: The overall incidence of ASD was 10.6% (11/103). The incidences of radiographic and symptomatic ASD were 8.7% (9/103) and 1.9% (2/103), respectively. All patients improved clinically and functionally during the follow-up period. Postoperative SL, preoperative SL, whole lumbar lordosis, and L1 axis S1 distance were significant risk factors for ASD. Only SL was a significant risk factor for both the preoperative and postoperative states. CONCLUSION: ASD may occur at a relatively lower incidence in adult low-grade isthmic spondylolisthesis compared with other degenerative lumbar spinal diseases. SL is significantly correlated with ASD, whereas mechanical alterations caused by LIF are less likely to affect the adjacent segment. Restoration of normal SL is important for preventing ASD, and long-term follow-up is necessary.

Purpose: Cervical sagittal balance plays important roles in transmitting the load of the head and maintaining global spinal balance. This study aimed to identify the association of cervical sagittal alignment with adjacent segment degeneration (ASD) and heterotopic ossification (HO) after Prestige-LP cervical disc replacement (CDR). Methods: We enrolled 132 patients who underwent one-level Prestige-LP CDR with 2–10 years of follow-up. Cervical sagittal alignment parameters, including the degree of C2–C7 lordosis (CL), functional spinal unit angle (FSUA), sagittal vertical axis (SVA),, and T1 slope (T1s), were measured. ASD and HO were evaluated at the last follow-up. Unpaired t tests and logistic regression analysis were used to identify the associations of cervical sagittal alignment with ASD and HO. Results: We found that patients who developed ASD showed significantly lower FSUA (2.1° vs. −1.4°, p < 0.001) and T1s values (28.4° vs. 25.5°, p = 0.029) after surgery. Similarly, the postoperative CL was significantly better in patients without ASD or HO (18.0° vs. 14.4°, p = 0.043). The decrease in the T1s at the last follow-up was significantly larger in the patients with ASD (−11.0° vs. −3.2°, p = 0.003), HO (−6.7° vs. −2.7°, p = 0.050), and ASD or HO (−7.0° vs. −0.8°, p < 0.001) than in those without ASD or HO. Multivariate logistic regression analysis showed that both the FSUA and T1s are associated with ASD and that the degree of CL is associated with postoperative complications. Conclusion: The results imply that maintaining cervical sagittal alignment after Prestige-LP CDR is important.

Abstract Purpose Cervical spine surgery may affect sagittal alignment parameters and induce accelerated degeneration of the cervical spine. Cervical sagittal alignment parameters of surgical patients will be correlated with radiological adjacent segment degeneration (ASD) and with clinical outcome parameters. Methods Patients were analysed from two randomized, double-blinded trials comparing anterior cervical discectomy with arthroplasty (ACDA), with intervertebral cage (ACDF) and without intervertebral cage (ACD). C2–C7 lordosis, T1 slope, C2–C7 sagittal vertical axis (SVA) and the occipito-cervical angle (OCI) were determined as cervical sagittal alignment parameters. Radiological ASD was scored by the combination of decrease in disc height and anterior osteophyte formation. Neck disability index (NDI), SF-36 PCS and MCS were evaluated as clinical outcomes. Results The cervical sagittal alignment parameters were comparable between the three treatment groups, both at baseline and at 2-year follow-up. Irrespective of surgical method, C2–C7 lordosis was found to increase from 11° to 13°, but the other parameters remained stable during follow-up. Only the OCI was demonstrated to be associated with the presence and positive progression of radiological ASD, both at baseline and at 2-year follow-up. NDI, SF-36 PCS and MCS were demonstrated not to be correlated with cervical sagittal alignment. Likewise, a correlation with the value or change of the OCI was absent. Conclusion OCI, an important factor to maintain horizontal gaze, was demonstrated to be associated with radiological ASD, suggesting that the occipito-cervical angle influences accelerated cervical degeneration. Since OCI did not change after surgery, degeneration of the cervical spine may be predicted by the value of OCI. NECK trial Dutch Trial Register Number NTR1289.

Abstract Purpose: To identify the importance of sagittal alignment with self-locked stand-alone cage (SSC) and anterior cage-with-plate (ACP) system after 3-level anterior cervical discectomy and fusion (ACDF) on cervical spondylotic myelopathy (CSM) after minimal 5-year follow-up.Methods: 38 patients with SSC system (SSC group) and 26 with ACP system (ACP group) from February 2007 to September 2013 were enrolled. Cervical alignment were C2-7 lordosis (CL), operated-segment CL (OPCL), upper and lower adjacent-segment CL (UCL and LCL) at preoperation (POP), immediate postoperation (IPO) and final follow-up (FFU). Clinical outcomes contained the neck disability index (NDI), the Japanese Orthopaedic Association (JOA) score and adjacent segment degeneration (ASD). Patients were divides into CL improved subgroup (IM subgroup) and non-improved subgroup (NIM subgroup).Results: There were improvements on CL and OPCL in both groups. The change of CL and OPCL larger in ACP group (P<0.05) but UAL and LAL were of no significance. NDI and JOA got improvement in both groups at IPO and FFU while ASD was in no difference between SSC and ACP. A total of 40 patients (18 vs 22) acquired CL improvement with a larger population in ACP group. There were no differences on the rate if ASD, NDI, JOA and their change between IM and NIM subgroup and the change of CL were not correlated with NDI, JOA and their change.Conclusion: SSC and ACP both provide long-term efficacy on OPCL correction with little impact on adjacent segment. The improvement of CL after three-level ACDF seems not so essential.
