Diffuse idiopathic skeletal hyperostosis may lead to osteophyte-associated pathologies of the aerodigestive tract. Preoperative investigations with esophageal and laryngoscopic examinations combined with fluoroscopic swallowing tests are essential. Surgical decompression through osteophytectomy and fusion is an effective management strategy in selected patients and should be considered when non-operative strategies have failed.

BackgroundThe stand-alone treatment of degenerative cervical spine pathologies is a proven method in clinical practice. However, its impact on subsidence, the resulting changes to the profile of the cervical spine and the possible influence of clinical results compared to treatment with additive plate osteosynthesis remain under discussion until present.MethodsThis study was designed as a retrospective observational cohort study to test the hypothesis that radiographic subsidence of cervical cages is not associated with adverse clinical outcomes. 33 cervical segments were treated surgically by ACDF with stand-alone cage in 17 patients (11 female, 6 male), mean age 56 years (33–82 years), and re-examined after eight and twenty-six months (mean) by means of radiology and score assessment (Medical Outcomes Study Short Form (MOS-SF 36), Oswestry Neck Disability Index (ONDI), painDETECT questionnaire and the visual analogue scale (VAS)).ResultsSubsidence was observed in 50.5% of segments (18/33) and 70.6% of patients (12/17). 36.3% of cases of subsidence (12/33) were observed after eight months during mean time of follow-up 1. After 26 months during mean time of follow-up 2, full radiographic fusion was seen in 100%. MOS-SF 36, ONDI and VAS did not show any significant difference between cases with and without subsidence in the two-sample t-test. Only in one type of scoring (painDETECT questionnaire) did a statistically significant difference in t-Test emerge between the two groups (p = 0.03; α = 0.05). However, preoperative painDETECT score differ significantly between patients with subsidence (13.3 falling to 12.6) and patients without subsidence (7.8 dropped to 6.3).ConclusionsThe radiological findings indicated 100% healing after stand-alone treatment with ACDF. Subsidence occurred in 50% of the segments treated. No impact on the clinical results was detected in the medium-term study period.

Both groups demonstrated equivalent clinical outcomes. HA and autologous bone from decompression sites can achieve similar fusion rates to those achieved with identical volumes of the gold standard autologous graft. The graft mixture can be used for one- or two-level lumbar spondylodeses to avoid donor site morbidity.

Introduction Solitary bone plasmacytoma (SP) is a rare diagnosis for which the primary treatment is local radiotherapy. There is no established consensus suggesting a total spondylectomy in spinal SP. Materials and Methods We report the case of a 43-yearold woman with solitary plasmacytoma of the lumbar spine treated with complete vertebral resection. Radiographs, CT scan and MRI showed a single osteolytic lesion of the third lumbar vertebra. Further diagnostics following recommended algorithm for tumour screening were negative.

Purpose The purpose of this study was to determine the extent to which magnetic resonance imaging (MRI) performed in patients with ankylosing spondylitis (AS) after low-and no-energy trauma leads to an improved diagnosis and, as a result, to a change in the therapeutic strategy. Methods All patients with AS, who underwent surgery after minor traumas (low-energy traumas, LETs) and patients without trauma history (NET: no-energy trauma), were retrospectively analysed. The diagnostic and planned surgical procedure was examined initially and again after total spine MRI in patients with persistent and/or new complaints. Results One hundred and thirty-six patients with AS after trauma were surgically treated. A total of 92 patients with LETs and 12 patients with NETs were included. After initial diagnostics (CT and X-ray) were performed in 15.4% of the patients with LET or NET (n = 16), we found occult fractures on MRI scans. In ten of these patients (6 LET, 4 NET) in which a previous decision was made to follow conservative therapy, no fracture indication was found on CT or X-ray. Two fracture heights were observed in six patients who experienced LET. However, on X-ray and CT, the fractures were only visible at one height. All fractures were treated surgically with stabilization and decompression if indicated. Conclusion Considering the high percentage of our patient population with occult fractures, we recommend supplementing the basic diagnostic procedures with an MRI of the entire spinal column in patients with painful spinal column findings after minor trauma and for those with persistent pain without trauma.

BackgroundLow back pain is a very common disorder. In this field chronic low back pain represents a special challenge. The management of chronic low back pain consists of a range of different intervention strategies. Usually operative intervention should be avoided if possible. However, there are constellations were surgical therapy in patients with chronic low back pain seems to be meaningful.The aim of this study was to investigate the clinical outcomes after spine surgery and hip replacement in patients with chronic low back pain after undergoing a structured rehabilitation program including cognitive – behavioral therapy.MethodsFrom January 1, 2007 to January 1, 2010 patients were indicated for total hip replacement (THA) or spine surgery after receiving inpatient multidisciplinary pain programs including cognitive – behavioral therapy at our orthopedic institute with a specialized unit for the rehabilitation of chronic pain patients. Indications for surgery were based on the synopsis of clinical and imaging findings and on positive effects after local injections during the multidisciplinary pain program. The tools for assessment included follow-up at 6 and 12 months and analyses of pain, chronicity, physical functioning and depression.ResultsOf the 256 patients admitted for multidisciplinary pain program, fifteen were indicated to benefit from a surgical intervention during multidisciplinary pain program. Ten patients received spine surgery. THA was indicated in five patients. In all cases, the peri- and postoperative clinical courses were uneventful. Only two of the patients subjected to spine surgery and three patients who had THA were improved after 12 months. One patient reported a worsened condition. All patients presented with good functional outcomes and normal radiological findings.ConclusionsThe indication for surgical intervention in patients with chronic low back pain and degenerative diseases must be critically assessed. THA in this cohort should focus on functional aspects, such as the improvement of range of motion, rather than the reduction of pain. Spine surgery in chronic low back pain patients after multidisciplinary pain program including cognitive – behavioral therapy cannot be recommended due to its questionable success.
