A Case Report of U-Type Sacral Fracture After Chiropractic Adjustment.

CASE: A U-type sacral fracture, or spinopelvic dissociation, resulting from chiropractic manipulation has not been described in the medical literature. This report presents the case of a 74-year-old male patient who sustained a U-type sacral fracture after drop-table chiropractic manipulation. CONCLUSION: Our case demonstrates that chiropractic manipulative therapy involving the commonly used drop-table can cause severe injury. The patient's course was complicated by a delay in diagnosis and a prolonged hospital stay. Orthopaedic surgeons should have a high degree of suspicion for spinopelvic dissociation in the setting of bilateral sacral fractures. One year after injury, with conservative management, the patient returned to baseline function with mild residual neuropathy.

Benefits and harms of non-surgical and non-pharmacological management of osteoporotic vertebral fractures: A systematic review and meta-analysis.

BACKGROUND: Osteoporotic vertebral fractures affect a large number of older adults OBJECTIVES: Systematically review evidence of the benefits and harms of non-surgical and non-pharmacological management of people with osteoporotic vertebral fractures compared with standard care (control); and evaluate the benefits and harms of non-surgical and non-pharmacological management of people with osteoporotic vertebral fractures compared with an alternative non-pharmacological, non-invasive intervention. DESIGN: Systematic review and meta-analysis of randomized controlled trials. Five electronic databases (CINAHL, EMBASE, MEDLINE, PUBMED, and COCHRANE) were searched. Eligible trials included participants with primary osteoporosis and at least one vertebral fracture diagnosed on radiographs, with treatment that was non-surgical and non-pharmacological involving more than one session. RESULTS: Twenty randomized controlled trials were included with 2083 participants with osteoporotic vertebral fractures. Exercise, bracing, multimodal therapy, electrotherapy, and taping were investigated interventions. Meta-analyses provided low certainty evidence that exercise interventions compared to no exercise were effective in reducing pain in patients with osteoporotic vertebral fractures (mean difference (MD)= 1.01; 95% confidence interval (CI): 0.08, 1.93), and low certainty evidence that rigid bracing intervention compared with no bracing was effective in reducing pain in patients with osteoporotic vertebral fractures (MD= 2.61; 95%CI: 0.95, 4.27). Meta-analyses showed no differences in harms between exercise and no exercise groups. No health-related quality of life or activity improvements were demonstrated for exercise interventions, bracing, electrotherapy, or multimodal interventions. CONCLUSIONS: Exercise and rigid bracing as management for patients with osteoporotic vertebral fractures may have a small benefit for pain without increasing risk of harm.

Osteoporotic Fractures of the Thoracic and Lumbar Vertebrae: Diagnosis and Conservative Treatment.

BACKGROUND: The prevalence of osteoporotic vertebral body fractures in Europe is 18-26%. Although most of these injuries can be treated conservatively, the underlying concepts have not been defined clearly or uniformly. In this article, we present the current state of the evidence on the diagnosis and conservative treatment of osteoporotic fractures of the thoracic and lumbar vertebrae. METHODS: A systematic review of the literature up to May 2020 was carried out in the PubMed and Web of Science Core Collection databases. 549 articles were identified, of which 36 were suitable for inclusion in the review. Articles were sought in the areas of diagnosis, provision of physical aids, pharmacotherapy, physiotherapy, and treatments from the realm of alternative medicine. RESULTS: The primary diagnostic technique was conventional x-ray in two planes (with the patient standing, if possible), which had 51.3% sensitivity and 75% specificity. If a fracture was suspected, magnetic resonance imaging (MRI) of the entire spine and regional computed tomography (CT) were carried out. The overall state of the evidence on treatment is poor; the best available evidence is for exercise therapy and physiotherapy, which are supported by three level I and four level II studies. Improvements were seen mainly in mobility and a reduced fear of falling. The use of an active orthosis can be useful as well. No evidence was found on the use of drugs or alternative medicine exclusively in the conservative treatment of osteoporotic vertebral body fractures. CONCLUSION: It is reasonable to evaluate instability with imaging repeatedly, at regular intervals, over a period of six months. There is still a lack of reliable data on the optimal intensity and duration of physiotherapy, and on the use of orthoses.

Vertebral fracture during one repetition maximum testing in a breast cancer survivor: A case report.

RATIONALE: One repetition maximum (1-RM) testing is a standard strength assessment procedure in clinical exercise intervention trials. Because no adverse events (AEs) are published, expert panels usually consider it safe for patient populations. However, we here report a vertebral fracture during 1-RM testing. PATIENT CONCERNS: A 69-year-old breast cancer survivor (body-mass-index 31.6 kg/m2), 3 months after primary therapy, underwent 1-RM testing within an exercise intervention trial. At the leg press, she experienced pain accompanied by a soft crackling. DIAGNOSIS: Imaging revealed a partially unstable cover plate compression fracture of the fourth lumbar vertebra (L4) with a vertical fracture line to the base plate, an extended bone marrow edema and a relative stenosis of the spinal canal. INTERVENTIONS: It was treated with an orthosis and vitamin D supplementation. Another imaging to exclude bone metastases revealed previously unknown osteoporosis. OUTCOMES: The patient was symptom-free 6.5 weeks after the event but did not return to exercise. CONCLUSION: This case challenges safety of 1-RM testing in elderly clinical populations. LESSONS: Pre-exercise osteoporosis risk assessment might help reducing fracture risk. However, changing the standard procedure from 1-RM to multiple repetition maximum (x-RM) testing in studies with elderly or clinical populations would be the safest solution.

[Analgesic effect of combined therapy of medication and acupuncture in PVP for osteoporotic vertebral compression fracture: a randomized controlled trial].

OBJECTIVE: To evaluate the analgesic effect and application advantage of acupuncture combined with local anesthesia of lidocaine in percutaneous vertebroplasty (PVP) for the patients with osteoporotic vertebral compression fracture (OVCF). METHODS: A total of 60 patients with OVCF and receiving PVP at single vertebra under local anesthesia were selected and randomized into an acupuncture plus medication group and a simple medication group, 30 cases in each one. In the simple medication group, the local laying infiltration anesthesia with 1% lidocaine 30 mL was used. In the acupuncture plus medication group, firstly, filiform needles were used to stimulate Hegu (LI 4), Neiguan (PC 6), Jinmen (BL 63) and Yintang (GV 29) with reducing technique, and then the epidermal infiltration anesthesia was followed with 1% lidocaine 4 mL. The needles were retained till the end of operation. Successively, before operation (T0), during skin incision (T1), at the time of working channel completion (T2) and at the time of the injection of bone cement by half a dose (T3), as well as at the end of operation (T4), the mean arterial pressure (MAP), heart rate (HR), oxygen saturation (SpO2) and numerical rating scale (NRS) score were recorded. Besides, the key time of operation and adverse reactions during the operation were recorded, as well as the hospital stays after operation and the subjective satisfaction of the patients. RESULTS: In the acupuncture plus medication group, MAP and HR were lower than those in the simple medication group at T2, T3 and T4 respectively (P<0.05). NRS scores in the acupuncture plus medication group were lower than the simple medication group at T1 and T2 respectively (P<0.05). The key time of operation in the acupuncture plus medication group was shorter than the simple medication group (P<0.05). The incidence of adverse reaction in the acupuncture plus medication group was lower than the simple medication group (P<0.05) and the excellence rate of subjective satisfaction was higher than the simple medication group (P<0.05). CONCLUSION: Acupuncture combined with medication reduces the dose and adverse reactions of anesthetics, alleviates pain degree of patients, shortens the duration of operation and improves patients' subjective satisfaction in PVP for OVCF.

Three-step Reduction Therapy of Integrated Chinese and Western Medicine for Thoracolumbar Burst Fracture.

Objective: To investigate and compare the efficacy of three-step reduction (TSR) therapy of integrated Chinese and Western Medicine and posterior open (PO) surgery for thoracolumbar burst fracture. Methods: We selected 60 patients diagnosed with thoracolumbar burst fracture and received treatment in our hospital from December 2014 to March 2017. According to randomized digital table, they were randomly divided into TSR and PO groups. VAS pain grade, Oswestry disability index, height of centrum front, Cobb's angle of spine, bleeding, and complication of internal fixation of the two groups were compared. Results: Postoperative reduction of injured centrum, regained volume of canalis vertebralis, volume of bleeding, and early functional rehabilitation of TSR group were better than that of PO groups (P < 0.05). Conclusion: Through three-step reduction combined pedicle screw fixation surgery, we can achieve satisfied reduction of thoracolumbar burst fracture, rebuild the height of centrum, recover the biomechanics function of spine, and reduce bleeding. Three-step reduction therapy is an effective therapy for thoracolumbar burst fracture.

Osteoporotic Thoracolumbar Fractures-How Are They Different?-Classification and Treatment Algorithm.

Osteoporotic vertebral fractures constitute at least 50% of the osteoporotic fractures that happen worldwide. Occurrence of osteoporotic fractures make the elderly patient susceptible for further fractures and increases the morbidity due to kyphosis and pain; the mortality risk is also increased in these patients. Most fractures occur in the thoracic and thoracolumbar region and are often stable. Different descriptive and prognostic classification systems have been described, but none are universally accepted. Radiographs, computed tomography, and magnetic resonance imaging are useful in imaging the fracture and evaluating the bone density. In acute stages, the fractures are well treated with conservative measures including short bed rest, analgesics, bracing, and exercises. Although most fractures heal well, up to 30% of fractures can develop painful nonunion, progressive kyphosis, and neurological deficit. For patients who develop severe pain not responding to nonoperative measures and painful nonunion, percutaneous cement augmentation procedures including vertebroplasty or kyphoplasty have been suggested. For fractures with severe collapse and that lead to neurological deficit and increasing kyphosis, instrumented stabilization is advised. Prevention and management of osteoporosis is the key element in the management of osteoporotic fractures in the elderly. Guidelines for essential adequate dietary and supplemental calcium and vitamin D, and antiosteoporotic medications have been described.

Treating the Aging Spine.

Demographic trends make it incumbent on orthopaedic spine surgeons to recognize the special challenges involved in caring for older patients with spine pathology. Unique pathologies, such as osteoporosis and degenerative deformities, must be recognized and dealt with. Recent treatment options and recommendations for the medical optimization of bone health include vitamin D and calcium supplementation, diphosphonates, and teriparatide. Optimizing spinal fixation in elderly patients with osteoporosis is critical; cement augmentation of pedicle screws is promising. In the management of geriatric odontoid fractures, nonsurgical support with a collar may be considered for the low-demand patient, whereas surgical fixation is favored for high-demand patients. Management of degenerative deformity must address sagittal plane balance, including consideration of pelvic incidence. Various osteotomies may prove helpful in this setting.

The Metastatic Spine Disease Multidisciplinary Working Group Algorithms.

The Metastatic Spine Disease Multidisciplinary Working Group consists of medical and radiation oncologists, surgeons, and interventional radiologists from multiple comprehensive cancer centers who have developed evidence- and expert opinion-based algorithms for managing metastatic spine disease. The purpose of these algorithms is to facilitate interdisciplinary referrals by providing physicians with straightforward recommendations regarding the use of available treatment options, including emerging modalities such as stereotactic body radiation therapy and percutaneous tumor ablation. This consensus document details the evidence supporting the Working Group algorithms and includes illustrative cases to demonstrate how the algorithms may be applied.

CAPACITIVE COUPLING ELECTRIC FIELDS IN THE TREATMENT OF VERTEBRAL COMPRESSION FRACTURES.

Positive effects of Capacitive Coupling Electric Field (CCEF) stimulation are described for several orthopedic indications such as the healing of recent fractures, non-unions and spinal fusion, due to the capacity to involve the up-regulation of osteopromotive factors. In vitro studies on MC3T3-E1 bone cells showed that CCEF acts opening the plasma membrane voltage gated calcium channels, thus increasing the cytosolic calcium concentration and the phospholipase A2 (PLA2) activity. Cytosolic calcium activates the calmodulin pathway, thus resulting in an up-regulated expression of osteogenic genes, such as transforming growth factor-ß superfamily genes (TGF-ß1, -ß2 -ß3, bone morphogenetic protein-2 and -4), fibroblast growth factor (FGF)-2, osteocalcin (BGP) and alkaline phosphatase (ALP). PLA2 acts increasing the synthesis of Prostaglandin E2 (PGE2), which promotes osteogenesis by raising the cellular L-ascorbic acid uptake through the membrane carrier sodium vitamin C transporter-2 (SVCT-2). In vivo, Brighton et al. in a castration-induced osteoporosis animal model, demonstrated that CCEF was able to restore bone mass/unit volume in the rat vertebral body. To investigate the role of CCEF stimulation in vertebral bone marrow edema (VBME) its percentage was assessed in 24 patients with 25 acute vertebral compression fractures (VCFs) conservatively treated with CCEF (group A) or without CCEF (group B) using serial MR imaging follow-up at 0, 30, 60, 90 days. Pain and quality of life were assessed by visual analog scale (VAS) and Oswestry Low Back Disability Index (ODI) in the same periods. At 90 day follow-up the complete resolution of VBME was found only in group A (p=0.0001). A significant improvement of VAS (p=0.007) and ODI (p=0.002) was also observed in group A. This preliminary observational study shows that patients treated with CCEF stimulation present an improvement of clinical symptoms with faster fracture healing and a complete VBME resolution.

Effects of transcutaneous electrical nerve stimulation on rats with the third lumbar vertebrae transverse process syndrome.

OBJECTIVE: To investigate the analgesic and anti-inflammatory effects of transcutaneous electrical nerve stimulation (TENS) at local or distant acupuncture points in a rat model of the third lumbar vertebrae transverse process syndrome. METHODS: Forty Sprague-Dawley rats were randomly divided into control, model, model plus local acupuncture point stimulation at BL23 (model+LAS) and model plus distant acupuncture point stimulation at ST36 (model+DAS) groups. All rats except controls underwent surgical third lumbar vertebrae transverse process syndrome modelling on day 2. Thereafter, rats in the model+LAS and model+DAS groups were treated daily with TENS for a total of six treatments (2/100 Hz, 30 min/day) from day 16 to day 29. Thermal pain thresholds were measured once a week during treatment and were continued until day 57, when local muscle tissue was sampled for RT-PCR and histopathological examination after haematoxylin and eosin staining. mRNA expression of interleukin-1 ß (IL-1ß), tumour necrosis factor-α (TNF-α) and inducible nitric oxide synthase (iNOS) was determined. RESULTS: Thermal pain thresholds of all model rats decreased relative to the control group. Both LAS and DAS significantly increased the thermal pain threshold at all but one point during the treatment period. Histopathological assessment revealed that the local muscle tissues around the third lumbar vertebrae transverse process recovered to some degree in both the model+LAS and model+DAS groups; however, LAS appeared to have a greater effect. mRNA expression of IL-1ß, TNF-α and iNOS in the local muscle tissues was increased after modelling and attenuated in both model+LAS and model+DAS groups. The beneficial effect was greater after LAS than after DAS. CONCLUSIONS: TENS at both local (BL23) and distant (ST36) acupuncture points had a pain-relieving effect in rats with the third lumbar vertebrae transverse process syndrome, and LAS appeared to have greater anti-inflammatory and analgesic effects than DAS.

Vertebral Bone Marrow Edema (VBME) in Conservatively Treated Acute Vertebral Compression Fractures (VCFs): Evolution and Clinical Correlations.

STUDY DESIGN: Prospective observational study. OBJECTIVE: To assess (1) the evolution of vertebral bone marrow edema (VBME) in patients with A1 vertebral compression fractures (VCFs) conservatively treated and (2) the relationship between VBME and clinical symptoms, evaluated as Visual Analogue Scale (VAS) back pain and Oswestry Disability Index (ODI). SUMMARY OF BACKGROUND DATA: VBME is a marker of acute-subacute vertebral fractures. Little is known about the evolution of VBME in conservatively managed VCFs, as well as its clinical meaning. METHODS: 82 thoracic or lumbar VCFs (21 post-traumatic; 61 osteoporotic VCFs), type A1 according to the AOSpine thoracolumbar spine injury classification system, in 80 patients were treated with C35 hyperextension brace for 3 months, bed rest for the first 25 days. Patients with osteoporotic fractures also received antiresorptive therapy and vitamin D supplementation. At 0 (T0), 30 (T1), 60 (T2), and 90 (T3) days, patients underwent magnetic resonance imaging evaluation and clinical evaluation, using VAS for pain and ODI.The paired t test was used to compare changes within groups at each follow-up versus baseline. The unpaired t test after ANOVA (analysis of variance) was used to compare the 2 groups at each follow-up.The association between VBME area, VAS score, and ODI score was analyzed by the Pearson correlation test. The tests were 2-tailed with a confidence level of 5%. RESULTS: A significant VBME mean area, VAS, and ODI scores reduction was recorded at 60 and 90-days follow-ups versus baseline. A positive correlation between VBME reduction and clinical symptoms improvement (VAS and ODI scores improvement) was found in both traumatic and osteoporotic VCFs. CONCLUSION: In benign A1 VCFs conservatively managed, VBME slowly decreases in the first 3 months of magnetic resonance imaging follow-up. This VBME reduction is related to clinical symptoms improvement. LEVEL OF EVIDENCE: 4.

A survey of outcomes and management of patients post fragility fractures in China.

UNLABELLED: We found that the fragility hip and vertebral fractures caused excess mortality rates in this Chinese female population, which was unexpectedly lower than those in western countries and other Asian countries. This was the first nationwide survey relating to post-fracture outcomes conducted among Chinese population in Mainland China. INTRODUCTION: This study aimed to investigate the mortality, self-care ability, diagnosis, and medication treatment of osteoporosis following fragility hip and vertebral fractures through a nationwide survey among female patients aged over 50 in Mainland China. METHODS: This was a multicenter, retrospective cohort study based on medical chart review and patient questionnaire. Female patients aged 50 or older admitted for low-trauma hip or vertebral fractures and discharged from Jan 1, 2008 to Dec 31, 2012 were followed. RESULTS: Total of 1151 subjects of hip fracture and 842 subjects of vertebral fracture were included. The mean age was 73.4 ± 10.0, and the median of duration from index fracture to interview was 2.6 years. The overall 1-year, 2-year, 3-year, 4-year, and 5-year cumulative mortality rates were 3.5, 7.0, 11.2, 13.1, and 16.9 %, respectively. The first year mortality rates in hip (3.8 %, 95% CI 3.3-4.4 %) and vertebral fracture (3.1 %, 95% CI 2.5-3.7 %) were significantly higher than that in the general population (1.6 %). Impaired self-care ability was observed in 33.2, 40.6, and 23.8 % of overall, hip fracture, and vertebral fracture group, respectively. The overall diagnosis rate of osteoporosis was 56.8 %, and bone mineral density (BMD) measurement had never been conducted in 42.0 % among these women. After the index fracture, 69.6 % of them received supplements and/or anti-osteoporotic medications, among which 39.6 % only received calcium with/without vitamin D supplementation. CONCLUSIONS: The osteoporotic hip and vertebral fractures caused excess mortality rates in this population of Mainland China. The current diagnosis and medical treatment following the fragility fractures is still insufficient in Mainland China.

Failure and success in the treatment of breast carcinoma in men: a case report.

BACKGROUND: Male breast cancer (MBC) represents a rare cause of vertebral body compression fractures along with severe pain restricting the patient's daily functioning. Limited number of cases, lack of awareness among patients and physicians leading to delayed management, further increase the average age and disease progression at presentation, resulting in a poor prognosis. Additionally, studies on MBC treatment protocols and the use of female algorithms are unavailable. The implementation of vertebroplasty or kyphoplasty often results in unsatisfactory outcome due to recurrent pain and loss of vertebral height. Stentoplasty could become an alternative procedure, as described in the following case study. CASE REPORT: 54-yr-old male patient with history of breast carcinoma presented with pain in the vertebral column. Baseline X-ray and CT scan revealed multiple osteosclerotic and osteolytic metastatic lesions in the thoracic vertebrae along with a compression fracture at T9. Stentoplasty was performed to limit fracture progression. Intraoperative scan revealed restoration of the vertebral body shape. Following surgery, direct reduction in pain was obtained. Postoperative 1-year follow-up did not show any loss in height of the operated vertebra. Results of adjuvant chemotherapy administration and a new method of treatment of compression fractures caused by metastatic lesions were compared with previously published studies. CONCLUSIONS: Stentoplasty with Vertebral Body Stenting-System is an innovative method that can be applied in kyphoplasty for compression fractures caused by metastatic lesions. Nevertheless, further research on the systemic treatment of MBC is needed.

Novel biodegradable electrospun nanofibrous P(DLLA-CL) balloons for the treatment of vertebral compression fractures.

Significant interest has been expressed by the spinal surgeon community for the use of calcium phosphate cement (CPC) in the treatment of vertebral compression fractures (VCFs), but the water-induced collapsibility and poor mechanical properties limit its clinical use. Here we fabricated novel electrospun nanofibrous P(DLLA-CL) balloons (ENPBs) using the nanotechnique of electrospinning. The ENPBs could separate the cements from the surrounding environment, and therefore can prevent the water-induced collapsibility of CPC and eliminate cement leakage. The ENPBs filling with CPC had enough load-bearing ability to restore the height of the fractured vertebral body and had no obvious effects on the initial strength and stiffness of natural bones. Further, the ENPBs had good biodegradability and cell proliferation ability. Calcium can be released from ENPBs filling with CPC. All these results strongly demonstrate ENPBs can be potentially used as CPC filling containers that keep the advantages and eliminate the disadvantages of CPC. FROM THE CLINICAL EDITOR: Calcium phosphate cement (CPC) is a promising modality in vertebral compression fracture treatment, but its water-induced collapsibility limits clinical applications. This team of investigators fabricated novel nanofibrous balloons using electrospinning, which enabled the separation of CPC from its surrounding environment, and therefore prevented water-induced collapsibility of CPC and eliminated cement leakage while maintaining all the advantages of CPC treatment.

[Efficacy analysis of intermediate screws technique plus injectable calcium sulfate for thoracolumbar fracture in postmenopausal patients].

OBJECTIVE: To explore the clinical efficacies of intermediate screws plus injectable calcium sulfate MIIGX3 for thoracolumbar fracture in postmenopausal patients. METHODS: A total of 21 postmenopausal patients with vertebral compression fractures reconstructed with posterior internal fixation of intermediate screws technique and anterior vertebral augmentation of MIIGX3 technique in three dimension were retrospectively analyzed. The changes of fracture vertebral height and Cobb's angle were compared.Visual analogue scale (VAS) was performed to evaluate their symptoms. All patients were followed up. RESULTS: Intermediate screws surgical technique plus MIIGX3 was successfully performed. The average injection dose was 4.6 ml.Leakage occurred intraoperatively in two cases. The average follow-up period was 15 (6-36) months. The VAS system demonstrated that pain decreased significantly (preoperative:7.8, postoperative:2.2). The height and Cobb's angle of fractured vertebra improved greatly. The preoperative values were 45.0 ± 6.4% and 19.4 ± 4.5° and postoperative ones 15.4 ± 3.9% and 8.64 ± 3.18° respectively. There was no occurrence of severe complications related with treatment.Except for 2 patients with a loss of 15% of vertebral height, the average heights of fractured vertebra in other 19 patients recovered to 85% of normal ones. CONCLUSION: Thoracolumbar fracture in postmenopausal patients may be managed satisfactorily by intermediate screws and injectable calcium sulfate technique.Such a technique is both safe and effective. And its stable and durable reduction offers significant improvement.

[Clinical observation of treating osteoporosis vertebral compression fracture of senile patients by restitution combined percutaneous vertebroplasty].

OBJECTIVE: To explore the methods and therapeutic efficacy of restitution combined with percutaneous vertebroplasty (PVP) for treating osteoporosis vertebral compression fracture (OVCF). METHODS: Recruited were 132 senile patients with OVCF who were willing to receive minimally invasive therapy were assigned to the comprehensive treatment group and the percutaneous kyphoplasty (PKP) group. The 89 vertebral bodies in the 68 cases of the comprehensive treatment group received restitution combined with PVP, while the 81 vertebral bodies in the 64 cases of the control PKP group received PKP alone. All patients completed the follow-ups for more than 3 years. The therapeutic efficacy was assessed using visual analogue scale (VAS), Oswestry disability index (ODI), Cobb's angle, the height ratios of the diseased vertebral anterior edge and middle edge. The operation time for a single centrum, the perspective time during the operation, the incidence of bone cement leakage, the injection rate of the bone cement, the cost of hospitalization, and the hospital days were compared between t he comprehensive treatment group and the PKP group. RESULTS: Compared with before treatment in the same group, the VAS and ODI were significantly lower, the height ratios of the diseased vertebral anterior edge and middle edge, and the Cobb's angle were obviously improved in the two groups, showing statistical difference (P < 0.01). There was no significant difference in the aforesaid indices between the two groups after treatment at the same time point (P > 0.05). There was no significant difference in the incidence of bone cement leakage, th e injection rate of the bone cement, or the hospital days between the two groups (P > 0.05). But the operation time f or individual vertebral body, the perspective time during the operation, and the cost of hospitalization were obviously less in the comprehensive treatment group than in the PKP group (P < 0.01). CONCLUSIONS: Restitution combined PVP could achieve the same therapeutic efficacy as that of the PKP. It could effectively restore the diseased vertebral height and correct the spinal kyphosis. Besides, there was no statistical difference in the incidence of bone cement leakage.

Nuevas estrategias en el tratamiento del trauma raquimedular: actualización bibliográfica / New strategies in treatment of spinal cord injury: literature update

Better understanding of spinal cord injury pathophysiology has allowed the development of new areas of investigation, focused in reducing the injury and stimulating cord regeneration. The preliminary results of these investigations have generated great expectation in the scientific world, together with ambiguous information for patients with these injuries. In this article, we present a review of the available literature in this area, describing several non-pharmacological interventions, together with new drugs, immune therapies to block processes that inhibit cord regeneration and the renowned cell therapy. After evaluating the available articles included in this review, we observed a progress towards an increased efficacy of these treatments, but with limitations due to methodological flaws in the study protocols, which do not allow us to make applicability recommendations of them in humans.
