BackgroundThe treatment of severe osteoporotic vertebral compression fractures (VCFs) with middle-column (MC) involvement, high fragmentation, large cleft and/or pedicular fracture is challenging. Minimally invasive 'stent-screw-assisted internal fixation' (SAIF) can reduce the fracture, reconstruct the vertebral body (VB) and fix it to the posterior elements.ObjectiveTo assess feasibility, safety, technical and clinical outcome of the SAIF technique in patients with severe osteoporotic VCFs.Methods80 treated vertebrae were analyzed retrospectively. Severe VCFs were characterized by advanced collapse (Genant grade 3), a high degree of osseous fragmentation (McCormack grade 2 and 3), burst morphology with MC injury, pediculo-somatic junction fracture, and/or large osteonecrotic cleft. VB reconstruction was evaluated on postprocedure radiographs and CT scans by two independent raters. Clinical and radiological follow-ups were performed at 1 and 6 months.ResultsSAIF was performed at 28 thoracic and 52 lumbar levels in 73 patients. One transient neurological complication occurred. VB reconstruction was satisfactory in 98.8% of levels (inter-rater reliability 96%, κ=1). Follow-up at 1 month was available for 78/80 levels and at 6 months or later (range 6–24, mean 7.9 months) for 73/80 levels. Significant improvement in the Visual Analog Scale score was noted at 1 and 6 months after treatment (p<0.05). Patients reported global clinical benefit during follow-up (Patient’s Global Impression of Change Scale 5.6±0.9 at 1 month and 6.1±0.9 at 6 months). Fourteen new painful VCFs occurred at different levels in 11 patients during follow-up, treated with vertebral augmentation or SAIF. Target-level stability was maintained in all cases.ConclusionsSAIF is a minimally invasive, safe, and effective treatment for patients with severe osteoporotic VCFs with MC involvement.

Object Symptomatic herniated thoracic discs remain a surgical challenge and historically have been associated with significant complications. While neurological outcomes have improved with the abandonment of decompressive laminectomy, the attempt to minimize surgical complications and associated morbidities continues through less invasive approaches. Many of these techniques, such as thoracoscopy, have not been widely adopted due to technical difficulties. The current study was performed to examine the safety and early results of a minimally invasive lateral approach for symptomatic thoracic herniated intervertebral discs. Methods Sixty patients from 5 institutions were treated using a mini-open lateral approach for 75 symptomatic thoracic herniated discs with or without calcification. The mean age was 57.9 years (range 23–80 years), and 53.3% of the patients were male. Treatment levels ranged from T4–5 to T11–12, with 1–3 levels being treated (mean 1.3 levels). The most common levels treated were T11–12 (14 cases [18.7%]), T7–8 (12 cases [16%]), and T8–9 (12 cases [16%]). Symptoms included myelopathy in 70% of cases, radiculopathy in 51.7%, axial back pain in 76.7%, and bladder and/or bowel dysfunction in 26.7%. Instrumentation included an interbody spacer in all but 6 cases (10%). Supplemental internal fixation included anterolateral plating in 33.3% of cases and pedicle screws in 10%; there was no supplemental internal fixation in 56.7% of cases. Follow-up ranged from 0.5 to 24 months (mean 11.0 months). Results The median operating time, estimated blood loss, and length of stay were 182 minutes, 290 ml, and 5.0 days, respectively. Four major complications occurred (6.7%): pneumonia in 1 patient (1.7%); extrapleural free air in 1 patient (1.7%), treated with chest tube placement; new lower-extremity weakness in 1 patient (1.7%); and wound infection in posterior instrumentation in 1 patient (1.7%). Reoperations occurred in 3 cases (5%): one for posterior reexploration, one for infection in posterior instrumentation, and one for removal of symptomatic residual disc material. Back pain, measured using the visual analog scale, improved 60% from the preoperative score to the last follow-up, that is, from 7.8 to 3.1. Excellent or good overall outcomes were achieved in 80% of the patients, a fair or unchanged outcome resulted in 15%, and a poor outcome occurred in 5%. Moreover, myelopathy, radiculopathy, axial back pain, and bladder and/or bowel dysfunction improved in 83.3%, 87.0%, 91.1%, and 87.5% of cases, respectively. Conclusions The authors' early experience with a large multicenter series suggested that the minimally invasive lateral approach is a safe, reproducible, and efficacious procedure for achieving adequate decompression in thoracic disc herniations in a less invasive manner than conventional surgical techniques and without the use of endoscopes. Symptom resolution was achieved at similar rates using this approach as compared with the most efficacious techniques in the literature, and with fewer complications in most circumstances.

Abstract Changes in vertebral body height depend on various factors which were analyzed in isolation and not as a whole. The aim of this study is to analyze what factors might influence restoration of vertebral body height after vertebral augmentation. We analyzed 48 patients (108 vertebrae) with osteoporotic vertebral fractures underwent vertebral augmentation when conservative treatment proved unsatisfactory. Analyses were carried out at the time of the fracture, during surgery (pre-cementation and post-cementation), at first medical check-up (6 weeks post-surgery) and at last medical check-up. Average vertebral height was measured and differences from preoperative values calculated at each timepoint. Pearson correlation coefficient and linear multivariable regression were carried out at the different timepoints. The time since vertebral fracture was 60.4 ± 41.7 days. Patients’ average age was 70.9 ± 9.3-years. The total follow-up was 1.43 ± 1-year. After vertebral cementation there was an increase in vertebral body height of + 0.3cm (13.6%). During post-operative follow-up, there was a progressive collapse of the vertebral body and pre-surgical height was reached. The factors that most influenced vertebral height restoration were: grade III collapse, intervertebral-vacuum-cleft (IVVC), and use of a flexible trocar before cement augmentation. The factor that negatively influenced vertebral body height restoration was location in the thoracolumbar spine.

Introduction: Open fractures are known as a major predisposing factor for a higher incidence of infection. The aim of this study was to assess the efficacy of antibiotic impregnated collagen sponge in reducing the risk of infection in open fractures Grade 3. Materials and Methods: This was an observational cohort study, evaluating the incidence of infection in open fractures of the femur Grade 3A/3B following insertion of gentamicin impregnated collagen sponge (Collatamp®) during definitive fracture fixation. Eryhtrocyte Sedimentation Rate (ESR) and total white count (TWC) were used as blood parameters to observe for the possibility of infection from pre-operatively up to follow up visits at the clinic. Results: A total number of 36 patients, whom had sustained open fracture of the femur Grade 3A/B, underwent internal fixation with antibiotic impregnated collagen sponge insertion. Overall, ESR and TWC in both male and female gender were downgoing trend, with p values of <0.001, and clinically there was no evidence of infection. No infection was identified in 97.2% of patients, following the internal fixation and antibiotic impregnated collagen sponge insertion. There was only one patient (2.8%) who developed infection following the definitive internal fixation and antibiotics impregnated collagen sponge insertion. Conclusion: The use of antibiotic impregnated collagen sponge in open fractures reduced the occurrence of infection. Furthermore, this allows for an uncomplicated union of the bone following definitive fixation.

ObjectiveThis study was performed to investigate the clinical effects of minimally invasive open reduction and internal fixation with a proximal femoral hollow locking plate on Pauwels type III femoral neck fractures.MethodsThe clinical data of 45 patients aged 32.0 ± 8.1 years (range, 19–45 years) with Pauwels type III femoral neck fractures treated from March 2012 to August 2016 were retrospectively analyzed. All patients underwent anterolateral minimally invasive open reduction and proximal femoral hollow locking plate fixation of the hip joint. Garden’s index was used to evaluate the quality of fracture reduction. Complications and fracture healing were recorded in all patients. At the last follow-up, the functional outcome was recorded using the Harris hip score.ResultsNo complications such as femoral neck shortening, internal fixation loosening, or refracture occurred. However, three patients required reoperation (one with nonunion and two with femoral head necrosis). At the last follow-up, the mean Harris hip score was 92.1 ± 4.5 (range, 76–98). The rate of excellent and good Harris hip scores was 93.3%.ConclusionThe herein-described strategy for Pauwels type III femoral neck fractures is advantageous in terms of high reduction quality, firm fixation, and prevention of neck shortening.

Object The use of minimally invasive noninstrumented fusions has increased as thoracoscopic approaches to the spine have evolved. The addition of instrumentation is infrequent, in part because of the lack of a minimally invasive implant system. The authors describe a technique for thoracoscopic plating after discectomy and report early clinical outcomes. Methods After a standard endoscopic discectomy and partial corpectomy and before exposure of the ventral thecal sac, the authors implanted a polyaxial screw and clamping element under fluoroscopic guidance. Reconstruction involves placement of autograft in the defect and subsequent placement of the remainder of the screw/plate construct with 2 screws per vertebral level. Results Twenty-five patients underwent thoracoscopic and thoracoscopy-assisted discectomies and fusion in which the aforementioned plate system was used. Of 19 patients presenting with pain, 10 had 6-month clinical follow-up with a greater than 50% reduction in visual analog scale score, which continued to improve up to 2 years postoperatively. There were 3 cases of pneumonia, 3 CSF leaks, 1 chyle leak, and 1 death due to a massive pulmonary embolus on the 1st postoperative day. Conclusions The authors conclude that thoracoscopic discectomy and plate-instrumented fusion can be achieved with acceptable results and morbidity. Further studies should evaluate the role of instrumented fusions after thoracoscopic discectomy in larger groups of patients and during a longer follow-up period.

Abstract BACKGROUND Spine stereotactic radiosurgery (SSRS) is a non-invasive technique that delivers ablative radiotherapy for optimal control of bony disease. While SSRS is known to provide excellent local control (LC) and minimal toxicity in adults, the role of SSRS in pediatrics is less clear. PURPOSE To evaluate SSRS in pediatric patients with spinal metastases. METHODS A retrospective review of patients (&lt;18 yrs) treated with SSRS at MDACC was performed after IRB approval. Descriptive statistics were utilized for analysis. RESULTS From 2011–2019, 12 metastatic osseous sites (3 cervical, 4 thoracic, 5 lumbar-sacral) in 9 patients were treated. Median follow-up was 9 months (range 2–41). Six males (67%) and 3 females (33%) all KPS ≥70, received radiation to ≤3 contiguous vertebral bodies. Median age was 16 yrs (range 8–18). No patients required sedation. Histologies included 7 osteosarcomas, one rhabdomyosarcoma and one Ewing’s sarcoma. Metastatic epidural spinal cord compression scores ranged from 0 (6), 1b (3) and 3 (3). No sites had surgery prior to SSRS and one site received prior conventional radiation. SSRS doses included 24 Gy in 1 fraction (7), 24–27 Gy in 3 fractions (4) and 50 Gy in 5 fractions (1). Six-month LC was 83% with one local failure following 27 Gy. OS at 6 and 12 mo were 55% and 23%. There was no grade ≥3 acute toxicity, no radiation myelopathy or vertebral compression fractures. CONCLUSION In this initial report, SSRS represents a promising modality that is well tolerated and provides excellent LC. However, further follow-up is warranted in the pediatric setting.

Abstract Background: Symptomatic osteoporotic vertebral compression fractures (OVCF) are increasing, as are acute and chronic pain episodes and progressive spinal deformities. However, there are no clear surgical treatment criteria for patients with these different symptoms. Therefore, this study aims to explore the surgical approaches for the treatment of OVCF with different symptoms and evaluate the feasibility of these surgical approaches.Methods: We retrospectively analyzed 238 symptomatic OVCF patients who entered our hospital from June 2013 to 2016. According to clinical characteristics and imaging examinations, these patients were divided into I-V grades and their corresponding surgical methods were developed. I, old vertebral fracture with no apparent instability, vertebral augmentation; II, old vertebral fracture with local instability, posterior reduction fusion internal fixation; III, old fractures with spinal stenosis, posterior decompression and reduction fusion and internal fixation; IV, old vertebral fracture with kyphosis, posterior osteotomy with internal fixation and fusion; V, a mixture of the above types, posterior osteotomy (decompression) with internal fixation and fusion. Postoperative visual analog score (VAS), oswestry disability index (ODI) scores, sagittal index (SI) and ASIA grades of neurological function were observed.Results: All 238 patients were followed up for 12-38 months, with an average follow-up of 18.5 months. After graded surgery, the VAS score, ODI score, and vertebral sagittal index SI of 238 patients were significantly improved, and the difference between the last follow-up results and the preoperative comparison was statistically significant (P˂0.05). Besides, the postoperative ASIA grades of 16 patients with nerve injury were improved from 14 patients with preoperative grade C, 2 patients with grade D to 4 patients with postoperative grade D and 12 patients with postoperative grade E.Conclusion: In this study, we concluded that graded surgery could better treat symptomatic old OVCF and restore spinal stability. This provides clinical reference and guidance for the treatment of symptomatic old OVCF in the future.
