Seventy patients with thoracrolumbar vertebrate fractures were treated by short-segment pedicle screw fixation and were randomly divided into two groups. Fractures in group A （n=20） were rein-forced with posterior morselized bone grafting in vertebrae for spinal fusion, while patients group B （n=50） did not receive the morselized bone grafting for bone fusion. The two groups were compared in terms of kyphotic deformity, anterior vertebral height, instrument failure and neurological functions after the treatment. Frankel grading system was used for the evaluation of neurological evaluation and Denis scoring scale was employed for pain assessment. The results showed that the kyphosis correction was achieved in both group A and group B （group A： 6.4 degree; group B： 5.4 degree）/At the end of follow-up, kyphosis correction was maintained in group A but lost in group B （P=0.0001）. Postoperatively, greater anterior height was achieved in group A than in group B （P〈0.01）. During follow-up study, anterior vertebral height was maintained only in Group A （P〈0.001）. Both group A and group B showed good Denis pain scores （P1 and P2） but group A outdid group B in terms of control of severe and constant pain （P4 and P5）. By Frankel criteria, the changes in neurological functions in group A was better than those of group B （P〈0.001）. It is concluded that reinforcement of short-segment pedicle fixation with morselized bone grafting for the treatment of patients with thoracolumbar vertebrae fracture could achieve and maintain kyphosis correction, and it may also increase and maintain anterior vertebral height. Morselized bone grafting in vertebrae offers immediate spinal stability in patients with thoracolumbar vertebrate fractures, decreases the instrument failure and provides better postoperative pain control than without the morselized bone grafting.展开更多

The aim of this study was to identify single nucleotide polymorphisms（SNPs） associated with total number of thoracic-lumbar vertebrae and for each trait（number of thoracic and lumbar vertebrae） separately. A total of 581 individuals from an F2 Large White×Minzhu population were genotyped using an SNP60 K chip. Performing a genome-wide association study（GWAS） for total number of thoracic-lumbar vertebrae, 38 significant SNPs were identified in two QTL regions located on SSC1 and SSC7. Performing a GWAS for number of thoracic vertebrae only, 72 significant SNPs were located on SSC7. While performing a GWAS for number of lumbar vertebrae only, 17 significant SNPs were identified on SSC1. Gene mining suggested that the gene encoding orphan nuclear receptor, germ cell nuclear factor（NR6A1） on SSC1 was a strong candidate affecting the number of lumbar vertebrae in pigs. Additionally, genes encoding vertnin（VRTN）, prospero homeobox 2（PROX2）, Finkel-Biskis-Jinkins murine osteosarcoma viral oncogene homolog（FOS）, and transforming growth factor beta 3（TGFB3） may be important candidates affecting the number of thoracic vertebrae in pigs. QTLs on SSC1 and SSC7 independently influenced the numbers of thoracic and lumbar vertebrae. These results shed light on the complex genetic background of vertebrae development in pigs.展开更多

Methods Orchiectomized and ovariectomized rat models are used to investigate sex hormone deficiency related osteoporosis and efficacy of different therapies. A rat vertebral body can be longitudinally divided into central portion, which contain more trabecular bone, and para-endplate portions which contain more compact bone. In matured male and female Wistar and Sprague-Dawley rat lumbar spines, we investigated baseline bone mineral density （BMD） characteristics and the differential segmental responses in bone loss within the lumbar vertebral body post gonadal surgery with clinical multidetector computed tomography. Results Para-endplate sections had a higher BMD than central sections. The cephalad para-endplate sections had a higher BMD than the caudad para-endplate sections. Eight weeks after gonadal removal, there was more bone loss in central sections than para-endplate sections. The relative difference of bone loss between para-endplate and central sections was more apparent in male rats than in female rats. There was more bone loss in caudad sections than cephalad sections; this lead to a further increase of BMD difference between caudad para-endplate sections and cephalad para-endplate sections post gonadal surgery. Conclusion The approach described in this study provided a consistent way to study BMD change within predominantly compact bone portion and trabecular bone portion of the vertebral body.展开更多

Traditionally, the elastic-model-based method was used to reconstruct 3 D shapes by deforming the control points on the elastic mesh. However, the reconstructed shape is not smooth because the limited control points are only distributed on the edge of the elastic mesh.Alternatively, statistical-model-based methods, which include shape-model-based and intensity-model-based methods, are introduced due to their smooth reconstruction. However, both suffer from limitations. With the shape-model-based method, only the boundary profile is considered, leading to the loss of valid intensity information. For the intensity-based-method, the computation speed is slow because it needs to calculate the intensity distribution in each iteration. To address these issues, we propose a new reconstruction method using X-ray images and a specimen’s CT data. Specifically, the CT data provides both the shape mesh and the intensity model of the vertebra. Intensity model is used to generate the deformation field from X-ray images, while the shape model is used to generate the patient specific model by applying the calculated deformation field.Experiments on the public synthetic dataset and clinical dataset show that the average reconstruction errors are 1.1 mm and1.2 mm, separately. The average reconstruction time is 3 minutes.展开更多

文摘BACKGROUND Although percutaneous vertebral augmentation(PVA)is a commonly used procedure for treating vertebral compression fracture(VCF),the risk of vertebral refracture should be considered.Chronic kidney disease-mineral and bone disorder(CKD-MBD)is a systemic disease of mineral and bone metabolism.It is associated with an increased risk of fracture.Few studies have reported the use of PVA in patients with CKD-MBD.We herein report a rare case wherein the cemented vertebra and the adjacent vertebra refractured simultaneously in a CKD-MBD patient after PVA.CASE SUMMARY A 74-year-old man suffered from low back pain after taking a fall about 3 wk ago.According to physical examination,imaging and laboratory findings,diagnoses of T12 VCF,CKD-MBD,and chronic kidney disease stage 5 were established.He then received percutaneous vertebroplasty at T12 vertebra.Fourteen weeks later,he presented with T12 and L1 vertebral refractures caused by lumbar sprain.Once again,he was given PVA which was optimized for the refractured vertebrae.Although the short-term postoperative effect was satisfactory,he reported chronic low back pain again at the 3-month follow-up.CONCLUSION It is necessary that patients with CKD-MBD who have received PVA are aware of the adverse effects of CKD-MBD.It may increase the risk of vertebral refracture.Furthermore,the PVA surgical technique needs to be optimized according to the condition of the patient.The medium-and long-term effects of PVA remain uncertain in patients with CKD-MBD.
文摘Fossil remains of snakes in Quaternary localities are most often represented by vertebrae.Therefore,it is necessary to carry out a comparative study of the vertebrae of modern species in the areas of interest to identify fossil materials.In this study,we examined 52 specimens of viperids(7 specimens of Gloydius intermedius,12 specimens of Gloydius ussuriensis,6 specimens of Gloydius halys,4 specimens of Vipera sakhalinensis,16 specimens of Vipera berus,and 7 specimens of Vipera renardi).The features of the trunk,cervical,cloacal and caudal vertebrae of 6 species from 2 genera are described.The vertebrae of the Viperidae are highly similar across species,with variation along the vertebral column.Nevertheless,they can be distinguished if their exact position within the vertebral column is known.The most important diagnostic feature is the shape of the hypapophysis,especially when identifying the cervical vertebrae.Among other morphological features,it is important to consider the shape of the ventral surface of the vertebra,prezygapophyseal and parapophyseal processes,neurapophysis,and zygapophysis.For the epistropheus,the position of the anterior edge of the neurapophysis in relation to the anterior edge of the neural arch is also significant.The caudal vertebrae bear the greatest resemblance.There is a significant overlap between the ratios of different measurements(indices)in different species.However,if an index is out of the overlapping zone,it is possible to identify a vertebra more or less accurately,especially when considering it in conjunction with other indices and morphological characteristics.

文摘Objective:To investigate the clinical efficacy and safety of percutaneous kyphoplasty at different surgical timings in the treatment of osteoporotic vertebral compression fracture(OVCF)based on the theory of“dynamic-static integration”.Methods:Patients with OVCF who underwent percutaneous kyphoplasty in our hospital were selected and divided into Groups A,B,and C for those undergoing surgery within 7,7—21,and>21 days of fracture occurrence.The variations in the amount of bone cement injected,pre-and post-operative pain levels,functional activity,deformity correction of the injured vertebrae,bone cement leakage,and vertebral body height loss were compared among the three groups.Results:Regarding pain relief and functional activity,the postoperative Visual Analog Scale and Oswestry Disability Index scores of the three groups significantly improved.Furthermore,the deformities of the injured vertebrae in the three groups were significantly corrected,with Groups A and B exhibiting superior correction compared to Group C.Moreover,the bone cement leakage rates in groups A and C were higher than that in Group B.At the 3-month follow-up,the loss of vertebral height in Group C was significantly higher than those in groups A and B.Conclusion:Kyphoplasty is effective for OVCF treatment.Early surgery can effectively restore the vertebral height of the injured vertebra,reduce kyphosis,and reduce height loss of the injured vertebra after surgery;nevertheless,treatment within 1—3 weeks of the fracture can reduce the occurrence of bone cement leakage,making the surgery safer.Therefore,surgical treatment within 1—3 weeks of fracture is safer and can achieve satisfactory therapeutic effects.From the perspective of traditional Chinese medicine,PKP surgery can transform the fracture end from a micromotion state to a fixed state,which fully embodies the theory of“dynamic-static integration”.

文摘Numbers of vertebrae is an important economic trait associated with body size and meat productivity in animals.However,the genetic basis of vertebrae number in donkey remains to be well understood.The aim of this study was to identify candidate genes affecting the number of thoracic(TVn)and the number of lumbar vertebrae(LVn)in Dezhou donkey.A genome-wide association study was conducted using whole genome sequence data imputed from low-coverage genome sequencing.For TVn,we identified 38 genome-wide significant and 64 suggestive SNPs,which relate to 7 genes(NLGN1,DCC,SLC26A7,TOX,WNT7A,LOC123286078,and LOC123280142).For LVn,we identified 9 genome-wide significant and 38 suggestive SNPs,which relate to 8 genes(GABBR2,FBXO4,LOC123277146,LOC123277359,BMP7,B3GAT1,EML2,and LRP5).The genes involve in the Wnt and TGF-βsignaling pathways and may play an important role in embryonic development or bone formation and could be good candidate genes for TVn and LVn.
文摘To enhance the fusion of graft bone in thoracolumbar vertebrae and minimize the postoperative loss of correction, short-segment pedicle screw fixation was reinforced with posterior moselizee bone grafting in vertebrae for spinal fusion in patients with thoracrolumbar vertebrate fractures. Seventy patients with thoracrolumbar vertebrate fractures were treated by short-segment pedicle screw fixation and were randomly divided into two groups. Fractures in group A （n=20） were rein-forced with posterior morselized bone grafting in vertebrae for spinal fusion, while patients group B （n=50） did not receive the morselized bone grafting for bone fusion. The two groups were compared in terms of kyphotic deformity, anterior vertebral height, instrument failure and neurological functions after the treatment. Frankel grading system was used for the evaluation of neurological evaluation and Denis scoring scale was employed for pain assessment. The results showed that the kyphosis correction was achieved in both group A and group B （group A： 6.4 degree; group B： 5.4 degree）/At the end of follow-up, kyphosis correction was maintained in group A but lost in group B （P=0.0001）. Postoperatively, greater anterior height was achieved in group A than in group B （P〈0.01）. During follow-up study, anterior vertebral height was maintained only in Group A （P〈0.001）. Both group A and group B showed good Denis pain scores （P1 and P2） but group A outdid group B in terms of control of severe and constant pain （P4 and P5）. By Frankel criteria, the changes in neurological functions in group A was better than those of group B （P〈0.001）. It is concluded that reinforcement of short-segment pedicle fixation with morselized bone grafting for the treatment of patients with thoracolumbar vertebrae fracture could achieve and maintain kyphosis correction, and it may also increase and maintain anterior vertebral height. Morselized bone grafting in vertebrae offers immediate spinal stability in patients with thoracolumbar vertebrate fractures, decreases the instrument failure and provides better postoperative pain control than without the morselized bone grafting.
文摘BACKGROUND As one of the most common complications of osteoporosis,osteoporotic vertebral compression fracture(OVCF)increases the risk of disability and mortality in elderly patients.Percutaneous vertebroplasty(PVP)is considered to be an effective,safe,and minimally invasive treatment for OVCFs.The recollapse of cemented vertebrae is one of the serious complications of PVP.However,the risk factors associated with recollapse after PVP remain controversial.AIM To identify risk factors for the recollapse of cemented vertebrae after PVP in patients with OVCFs.METHODS A systematic search in EMBASE,MEDLINE,the Cochrane Library,and PubMed was conducted for relevant studies from inception until March 2020.Studies investigating risk factors for the recollapse of cemented vertebrae after PVP without additional trauma were selected for analysis.Odds ratios(ORs)or standardized mean differences with 95%confidence interval(CI)were calculated and heterogeneity was assessed by both the chi-squared test and the I-squared test.The methodological quality of the included studies was assessed according to the Newcastle-Ottawa Scale.RESULTS A total of nine case-control studies were included in our meta-analysis comprising 300 cases and 2674 controls.The significant risk factors for the recollapse of cemented vertebrae after PVP in OVCF patients were fractures located at the thoracolumbar junction(OR=2.09;95%CI:1.30 to 3.38;P=0.002),preoperative intravertebral cleft(OR=2.97;95%CI:1.93 to 4.57;P<0.00001),and solid lump distribution pattern of the cement (OR = 3.11;95%CI: 1.91 to 5.07;P < 0.00001).The analysis did not support that age, gender, lumbar bone mineral density,preoperative visual analogue scale score, injected cement volume, intradiscalcement leakage, or vertebral height restoration could increase the risk forcemented vertebra recollapse after PVP in OVCFs.CONCLUSIONThis meta-analysis suggests that thoracolumbar junction fractures, preoperativeintravertebral cleft, and solid lump cement distribution pattern are associatedwith the recollapse of cemented vertebrae after PVP in OVCF patients.

The author has treated 66 cases by massotherapy, who were confirmatively diagnosed as having protrusion of the lumbar intervertebral disc by X-ray film and computer-aided tomography, with satisfactory results as reported in the following.Clinical DataAmong the 66 cases in this series, 49 were male and 17 female, ranging in age from 26 to 59 years, averaging 36.2 years. All the patients had got lumbago and unilateral ischialgia, with the left side affected in 37 cases and the right side in 29 cases. The leg pain radiating to lateral malleolus was found in 28 cases, to dorsum of the foot in 24 cases, and to the toes in 14 cases. Intermittent claudication was present in 22 cases, numbness of the affected foot in 16 cases, pain exacerbated when coughing in 35 cases, scoliosis in 21 cases, and positive Lasegue's sign in 48 cases.
文摘Fifty-six cases of the protrusion of the lumbar intervertebral disc in the treatment group were treated by drug-penetration and oral administration of traditional Chinese decoction plus traction, and the other 35 cases in the control group by oral administration of Chinese decoction and traction. The results showed that the cure rate in the treatment group was 83.9%, and that in the control group was 57.1%, with a statistically significant difference between the two groups (P<0.01), indicating that the former is a more effective therapy for protrusion of the lumbar intervertebral disc.
文摘Since 1996,the author has treated 40 cases of protrusion of lumbar intervertebral disc with ultra short wave and the point injection,and obtained good therapeutic effects.This is reported as follows.

文摘Although quantitative trait loci（QTLs） for number of thoracic-lumbar vertebrae have been identified on Sus scrofa chromosomes（SSCs） 1 and 7, the influence of these QTLs on the thoracic and lumbar vertebrae is not clear. The aim of this study was to identify single nucleotide polymorphisms（SNPs） associated with total number of thoracic-lumbar vertebrae and for each trait（number of thoracic and lumbar vertebrae） separately. A total of 581 individuals from an F2 Large White×Minzhu population were genotyped using an SNP60 K chip. Performing a genome-wide association study（GWAS） for total number of thoracic-lumbar vertebrae, 38 significant SNPs were identified in two QTL regions located on SSC1 and SSC7. Performing a GWAS for number of thoracic vertebrae only, 72 significant SNPs were located on SSC7. While performing a GWAS for number of lumbar vertebrae only, 17 significant SNPs were identified on SSC1. Gene mining suggested that the gene encoding orphan nuclear receptor, germ cell nuclear factor（NR6A1） on SSC1 was a strong candidate affecting the number of lumbar vertebrae in pigs. Additionally, genes encoding vertnin（VRTN）, prospero homeobox 2（PROX2）, Finkel-Biskis-Jinkins murine osteosarcoma viral oncogene homolog（FOS）, and transforming growth factor beta 3（TGFB3） may be important candidates affecting the number of thoracic vertebrae in pigs. QTLs on SSC1 and SSC7 independently influenced the numbers of thoracic and lumbar vertebrae. These results shed light on the complex genetic background of vertebrae development in pigs.

Methods： Ninety patients with VBIV were randomly divided into two groups; 45 patients （the treated group） were treated with YXDM and BHI intravenous dripping, once a day for 14 days. Another 45 patients （control group） were treated with Xueshuantong （血栓通） and BHI intravenous dripping, once daily for 14 days. The clinical syndromes and the index of the transcranial Doppler （TCD） and hemorheology were observed. Results： The total effective rate was 100% in the treated group, which was better than that in the control group 90.5%, （P〈0. 05）. The indexes of TCD and hemorheology in the treated group were obviously improved after treatment, （P〈0.01）. Conclusion： YXDM combined with BHT injection had better effect in treating patients with VBIV is an ideal drug for VBIV.

文摘Objective To investigate sex hormone deficiency related osteoporosis and efficacy of different therapies. Methods Orchiectomized and ovariectomized rat models are used to investigate sex hormone deficiency related osteoporosis and efficacy of different therapies. A rat vertebral body can be longitudinally divided into central portion, which contain more trabecular bone, and para-endplate portions which contain more compact bone. In matured male and female Wistar and Sprague-Dawley rat lumbar spines, we investigated baseline bone mineral density （BMD） characteristics and the differential segmental responses in bone loss within the lumbar vertebral body post gonadal surgery with clinical multidetector computed tomography. Results Para-endplate sections had a higher BMD than central sections. The cephalad para-endplate sections had a higher BMD than the caudad para-endplate sections. Eight weeks after gonadal removal, there was more bone loss in central sections than para-endplate sections. The relative difference of bone loss between para-endplate and central sections was more apparent in male rats than in female rats. There was more bone loss in caudad sections than cephalad sections; this lead to a further increase of BMD difference between caudad para-endplate sections and cephalad para-endplate sections post gonadal surgery. Conclusion The approach described in this study provided a consistent way to study BMD change within predominantly compact bone portion and trabecular bone portion of the vertebral body.

文摘Structure reconstruction of 3 D anatomy from biplanar X-ray images is a challenging topic. Traditionally, the elastic-model-based method was used to reconstruct 3 D shapes by deforming the control points on the elastic mesh. However, the reconstructed shape is not smooth because the limited control points are only distributed on the edge of the elastic mesh.Alternatively, statistical-model-based methods, which include shape-model-based and intensity-model-based methods, are introduced due to their smooth reconstruction. However, both suffer from limitations. With the shape-model-based method, only the boundary profile is considered, leading to the loss of valid intensity information. For the intensity-based-method, the computation speed is slow because it needs to calculate the intensity distribution in each iteration. To address these issues, we propose a new reconstruction method using X-ray images and a specimen’s CT data. Specifically, the CT data provides both the shape mesh and the intensity model of the vertebra. Intensity model is used to generate the deformation field from X-ray images, while the shape model is used to generate the patient specific model by applying the calculated deformation field.Experiments on the public synthetic dataset and clinical dataset show that the average reconstruction errors are 1.1 mm and1.2 mm, separately. The average reconstruction time is 3 minutes.
文摘In the present study, 121 patients with lumbar vertebra hyperosteogeny were dividedinto following four groups for treatment and comparison: intense electro-acupuncture group (Group1), hydro-acupuncture group (Group 2), electro-acupuncture plus hydro-acupuncture group (Group3) and analgesic liquid for spur group (Group 4). It is indicated that the effect of electro-acupunctureplus hydro-acupuncture is the best in the treatment of lumbar vertebra hyperosteogeny.

文摘BACKGROUND Scedosporium apiospermum(S.apiospermum)is a clinically rare and aggressive fungus mainly found in contaminated water,wetlands,decaying plants,stagnant water,and potted plants in hospitals.The lung,bone,joint,eye,brain,skin,and other sites are easily infected,and there is a marked risk of misdiagnosis.There have been few case reports of infection by S.apiospermum of the lumbar vertebrae;most reports have focused on infection of the lung.CASE SUMMARY An otherwise healthy 60-year-old man presented with a 4-mo history of lumbosacral pain,stooping,and limited walking.The symptoms were significantly aggravated 10 d prior to hospitalization,and radiating pain in the back of his left lower leg developed,which was so severe that he could not walk.Movement of the lumbar spine was significantly limited,anterior flexion was about 30°;backward extension,right and left lateral curvature,and rotational mobility were about 10°;tenderness of the spinous processes of the lumbar 3-5 vertebrae was evident,and the muscle strength of both lower limbs was gradeⅣ.Imaging suggested bony destruction of the lumbar 3,4,and 5 vertebrae and sacral 1 vertebra;in addition,the corresponding intervertebral spaces were narrowed and the lumbar 5 vertebra was posteriorly displaced and unstable.Lumbar vertebral infection was also noted,and the possibility of lumbar tuberculosis was considered.We first performed surgical intervention on the lesioned lumbar vertebrae,cleared the infected lesion,and performed stable fixation of the lesioned vertebral body using a lumbar internal fixation device,which restored the stability of the lumbar vertebrae.Cytological and pathological examination of the lesioned tissue removed during surgery confirmed S.apiospermum infection of the lumbar vertebrae;on this basis,the patient was administered voriconazole.At the 6-mo followup,efficacy was significant,no drug-related side effects were observed,and imaging examination showed no evidence of recurrence.CONCLUSION S.apiospermum infection can occur in immunocompetent individuals with no history of near drowning.Voriconazole is effective for the treatment of S.apiospermum infection of the lumbar vertebrae for which it is suitable as the first-line therapy.
