Techniques of vertebral body augmentation have been developed in an effort to treat these refractory cases. The injection of low-viscosity poly-methylemethacrylate (PMMA) under high pressure poses a potential risk for neural compromise and pulmonary embolism by uncontrolled leakage. Therefore, balloon kyphoplasty and vertebroplasty using a large cannula low pressure injection of PMMA in a high-viscosity state has been introduced. Percutaneous kyphoplasty (PKP) is a recently developed, minimally invasive surgical approach for the treatment of osteoporotic vertebral compression fractures (OVCF). Objective Our objective is directed towards the study of the role of kyphoplasty in the management of osteoporotic thoracolumbar fractures, following the analysis of clinical and radiographic outcomes. Our objective is to evaluate the efficacy and safety of kyphoplasty in the treatment of acute vertebral osteoporotic compression fractures and to validate the hypothesis that kyphoplasty will help diminish pain, disability and improve the quality of life (QoL). The goal of this study was to determine the safety and effectiveness of kyphoplasty in improving vertebral body height, decreasing pain, and improving affected functions. Patients and Methods A prospective analysis of 30 patients (10 males and 20 females), being treated with kyphoplasty, was performed at our institution, after a clinical follow-up of 6 months. The patients had vertebral compression fractures (VCFs) at levels T7 to L4 due to osteoporosis arising from primary and secondary etiological factors. There were 41 VCFs in these 30 patients. The median age was 69 years (range 53-87 years). Subjects were excluded if they had associated spinal stenosis, neurologic deficit, an active infection, and severe comorbidities, such as uncorrected coagulopathy. Results According to the pain scores, 26 (87%) patients showed a drastic post-operative improvement whereas, in 2 cases, significant improvement was noted after a follow-up in 3 months. On the other hand, 2 (7%) patients showed a deteriorated pain score. 24 (80%) patients showed constant improvement over a period of 6 months. 7 patients (23%) showed further improvement after the 6 months clinical follow-up. Conclusion All PMMA extravasations were asymptomatic; the cement was observed at a close vicinity to the treated vertebrae. We treated 41 fractures with balloon kyphoplasty (BKP); however, the failure of balloon distension occurred in 6 fractures (14%), which were managed with conventional vertebroplasty; Therefore, the exact cause behind the failure of the procedure is still unclear.

Eight patients (mean age 47.6 years) underwent MIS for LDLLS involving in all but one the L5-S1 level. VAS and ODI were used for clinical assessment. Imaging included pre-operative X-rays, CT and MRI scans. Post-operatively, all patients underwent X-rays and CT-scans. Pelvic incidence (PI), pelvic tilt (PT) and sacral slope (SS) values as well as lumbar lordosis (LL) have been derived from pre- and post-operative standard X-rays. Mean follow-up is 30.12 months (range 15-42). No complications related to the surgical procedure were observed. Patients reported a satisfactory clinical outcome, as demonstrated by variation in mean VAS (from 9.1 to 3.6) and ODI (from 70.50 to 28.25 %) scores. Comparison between pre- and post-operative sacro-pelvic parameters documented moderate changes, with reduction of PT and increase of SS in all but one patient. Overall sagittal balance of the spine has been evaluated using the sagittal vertical axis (SVA), obtained from post-operative X-rays. Mean value of SVA demonstrated a good sagittal balance of the spine. This series demonstrates that MIS is feasible and effective for LDLLS, as witnesses by the satisfactory clinical results maintained at medium-term follow-up. We submit that TLIF is a valid option but an adequately sized and positioned interbody cage is a key factor to allow satisfactory restoration of segmental lordosis.

The use of standard plate in a minimally invasive technique is both possible and advantageous to patient outcome. Prospective surgeon-randomized blinded outcome clinical study comparing new technique to conventional technique. Pain, operative time and mean hemoglobin drop in percutaneous hip fixation. The minimally invasive technique had significantly less blood loss (P < 0.001), operative time (P < 0.001) and a trend to less morphine use. Minimal invasive technique significantly reduces blood loss and operative time for fixation of intertrochanteric hip fractures without sacrifice of fixation stability or bone healing.
