ABSTRACT

OBJECTIVE@#To compare the efficacy between vesselplasty and percutanous kyphoplasty (PKP) in the treatment of Kümmell disease.@*METHODS@#The clinical data of patients with Kümmell disease from July 2018 to December 2019 were retrospectively analyzed. According to the different therapeutic methods, the patients were divided into vesselplasty group and PKP group. There were 20 patients in vesselplasty group, including 2 males and 18 females, aged from 54 to 83 years with an average of (67.40±7.44)years, 1 case of T10 fracture, 3 cases of T12 fracture, 9 cases of L1 fractures, 5 cases of L2 fractures and 2 cases of L3 fractures. There were 20 patients in PKP group, including 3 males and 17 females, aged from 56 to 81 with an average of(67.20±7.01) years, 2 cases of T10 fracture, 1 case of T11 fracture, 6 cases of T12 fracture, 10 cases of L1 fracture and 1 case of L3 fracture. Visual analogue scale(VAS), Cobb angle, anterior vertebral height were recorded before operation, 1 day after operation and 1 year after operation. Oswestry Disability Index(ODI) was recorded before operation, 1 month after operation and 1 year after operation. And bone cement leakage rate was compared between two groups after operation.@*RESULTS@#All the patient were followed up for more than 1 year. In vesselplasty group, VAS score was 1.20±0.41, ODI was(13.50±3.10)%, Cobb angle was(17.20±3.12)° and anterior vertebral height was(20.20±1.35) mm at 1 year after operation. In PKP group, VAS score was 1.15±0.40, ODI was (13.20±3.00)%, Cobb angle was (17.10±3.19)° and anterior vertebral height was (20.10±1.37) mm at 1 year after operation. These index was significantly better than pre-operation through intra-group comparison(P<0.05), and there was no statistically difference between the two groups(P>0.05). There were 20 cases (20 vertebrae) in vesselplasty group, of which 1 case had bone cement leakage at the upper endplate, with a leakage rate of 5%(1/20). In PKP group, there were 20 cases (20 vertebrae), 3 cases of upward endplate leakage(3/7), 1 case of downward endplate leakage(1/7), 1 case of leakage to the front of the vertebral body(1/7), 2 cases of leakage to the side of the vertebral body(2/7), with a leakage rate of 35% (7/20). The difference between two groups was statistically significant(P<0.05).@*CONCLUSION@#Vesselplasty in the treatment of Kümmell disease can better reduce leakage rate of bone cement and reduce complications.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the validity and reliability of Thread-tooth Arc-track Screw Plate System (TASPS) in the fixation fusion through expandable channels.</p><p><b>METHODS</b>From August 2007 to August 2010, 108 patients with lumbar instability were treated with surgery, including 61 males and 47 females, ranging in age from 26 to 57 years, with an average of 41 years. All the patients were divided into two groups : minimally invasive fusion group and traditional operation group (54 patients in each group). The patients in the minimally invasive fusion group were treated with self-designed TASPS to conduct the fixation fusion through expandable channels by minimally invasive pedicle screw; and the patients in traditional operation group were treated with traditional interbody fixation fusion by pedicle screw. The data were collected and investigated at the 1st week, 3rd month and 1st year postoperatively. The comparative parameters of two groups contained the total operation time, the implanted time, the total amount of bleeding; the VAS score, ODI score and improvement rate at each investigated period; the intervertebral space height of preoperative and postoperative periods; the inefficiency rate of implantation and the fusion rate of postoperative period.</p><p><b>RESULTS</b>All incisions were healed by first stage without any complications such as dural tear, injury of nerve root or cauda equine, intervertebral space infection. The patients in the minimally invasive fusion group needed longer operative time than that of the traditional operation group, but had less total amount of intraoperative and postoperative bleeding and shorter implanted time of pedicle screw than those of the traditional operation group. The VAS scores of two groups at the 1st week after operation significantly decreased compared with that of the 1st day before the operation, and the difference was of high statistical significance. And the VAS scores of two groups at the 3rd month and 1st year after operation also significantly decreased compared with that of the 1st day before the operation, and the difference was highly statistically significant. By comparing the VAS score and ODI score at the 1st week, 3rd month and 1st year postoperatively, the results showed that the VAS score and ODI score of the minimally invasive fusion group were all lower than those of the traditional operation group, and the differences were of high statistical meaningfulness. After 1 year, the improvement rate of the minimally invasive fusion group was (77.46 +/- 6.34)%, while that of the traditional operation group was (72.73 +/- 4.49)%, and the difference was highly statistically significant (P < 0.01). The intervertebral space heights of two groups remarkably increased. At the 3rd month after operation, the difference of intervertebral space heights of the two groups was of no statistical significance. At the 1st year after operation, intervertebral space heights of the two groups were lost to some extent, but the height of the minimally invasive fusion group was higher than that of the traditional operation group, and the difference was statistically significant. The fusion rates of the two groups after 1 year were 100%.</p><p><b>CONCLUSION</b>The fixation fusion through expandable channels by minimally invasive pedicle screw possesses the characteristics of fewer traumas, less intraoperative blood loss, less postoperative pain and rapid recovery. Since its intervertebral fusion rate is similar to the open surgery, it can be viewed as one effective approach for the treatment of lumbar instability diseases. And TASPS is reasonably designed, easy to install and reliably fixed with good reduction effect, which can be applied through expandable channels.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate methods and therapeutic effects of sequential drugs treatment for central pain following spinal cord injury.</p><p><b>METHODS</b>A total of 28 patients suffered from central pain following spinal cord injury were treated with sequential drugs from 1994 to 2008, including 23 males and 5 females, ranging in age from 25 to 59 years (mean 42 years). According to the patients' response to drugs, the therapy grade was adjusted step by step until the pain was relieved. Basing on VAS scores before and after drugs treatment, analgesic effect was evaluated. The first grade drugs: COX-2 inhibitors. The second grade drugs: Tricyclic antidepressant drugs (Amitriptyline) + COX-2 inhibitors + Carbamazepine. The third grade drugs: Tricyclic antidepressant drugs (Amitriptyline) + Gabapentin + Neurotropin/COX-2 inhibitors.</p><p><b>RESULTS</b>The pain of all of 28 patients was relieved to different extent. The VAS scores decreased by 23.3 +/- 1.2 in the first grade drugs treatment group. The VAS scores decreased by 54.5 +/- 3.8 in the second grade drugs treatment group. The VAS scores decreased by 65.8 +/- 5.1 in the third grade drugs treatment group (P<0.05).</p><p><b>CONCLUSION</b>The sequential drugs treatment for central pain following spinal cord injury has a good analgesia effect and little adverse reaction.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To compare the effect between mini-traumatic bone-grafting and non-bone-grafting in percutaneous K-wire fixation for treating the calcaneal fractures.</p><p><b>METHODS</b>From 2002 to 2006, 112 patients with the type II (Paley type) fractures of calcaneus were studied. There were 56 cases in bone-grafting group involving 36 males and 20 famales,aged from 21 to 65, averaged (42.0 +/- 2.3) years; 11 cases were in type II a and 45 were in type II b; the course was from 3 to 14 days, averaged (6.0 +/- 1.2) days. And there were 56 cases in non-bone-grafting group involving 38 males and 18 famales,aged from 22 to 67, averaged (43.0 +/- 2.5)years; 13 cases were in type II a and 43 were in type II b; the course was from 2 to 15 days, averaged (5.0-2.1) days. All the cases were treated by closed reduction and percutaneous K-wire fixation, and bone-grafting group(56 cases) were treated by mini-traumatic bone-grafting, but the other group (56 cases) were not. The collapsing rate and fineness rate were compared.</p><p><b>RESULTS</b>All the cases were followed up from 5 to 52 months. There were no collapsing cases in the bone-grafting group after operation, but 3 cases occurrenced re-collapsing in the non-bone-grafting group. According to the Zhang Tie-liang's evaluation criterion, in the bone-grafting group,the results were excellent in 43 cases, good in 12, fair in 1, the fineness rate was 98.2%. In the non-bone-grafting group,the results were excellent in 37 cases, good in 16, fair in 2, poor in 1, the fineness rate was 94.7%.</p><p><b>CONCLUSION</b>Treatment of the type II fracture of calcaneus with closed reduction, percutaneous K-wire fixation and mini-traumatic bone-grafting can prevent the posterior talar articular surface of caltaneus from collapsing again after operation, enhance the union of fracture, elevate the curative effect, thus it should be taken with the standard therapeutic regimen.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To introduce a new method using calcium phosphate cement/Danshen drug delivery system for treating ischemic necrosis of the femoral head and evaluate its curative effect.</p><p><b>METHODS</b>From May 2000 to June 2005, 48 adult patients (54 hips) with ischemic necrosis of the femoral head at Stages I, II and III of antigen reactive cell opsonization (ARCO) were treated with implantation of calcium phosphate cement/Danshen drug delivery system in the involved femoral head. The operation consisted of removal of the necrotic bone under weight-loading cartilage and the implantation of phosphate cement/Danshen drug delivery system, and all manipulations were made percutaneously through a bone tunnel in the trochanter. The functions of the hip joint were evaluated and X-ray films were taken preoperatively and postoperatively.</p><p><b>RESULTS</b>Postoperative follow-up was 45.5 months on average, ranging from 27 to 78 months. According to the evaluation criterion of "Dandong 1995" for therapeutic effect of adult ischemic necrosis of the femoral head, the therapeutic effects were excellent in 33 hips, good in 17, fair in 3 and poor in 1, with the excellent and good rate of 92.6%.</p><p><b>CONCLUSIONS</b>This method is relatively simple with little invasion. It not only improves the microcirculation of the femoral head by local application of traditional Chinese medicine, but also provides mechanic buttress in the weight-loading area to prevent collapse during repairing, which is beneficial to repair and reconstruction of femoral head. It may be a choice of minimal invasion surgery for ischemic necrosis of the femoral head at Stages I, II and III of ARCO.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the biomechanical performance of the spinal universal fixation system(GSPS) in treating the diseases related to spinal instability.</p><p><b>METHODS</b>Four instable models and 4 fracture models were made of fresh pig's thoracolumbar specimens (T10-L3). Self-designed GSPS were used in the simulated operation. Axial loading test and torsion test were made. The stress-strain relation of the GSPS was observed. The extracting force of link bar from elastic jig was tested.</p><p><b>RESULTS</b>The strain value of each tested point changed linearly when the axial load changed from 0 to 600 N. There was linear relation between the torsion and the torsion angle. The latter was less than 6 degrees when the former reached 300 N x cm. The minimum extracting force of the link bar from the elastic jig was more than 3 300 N.</p><p><b>CONCLUSION</b>The GSPS has high energy and high elasticity on anti-axial and anti-torsion load. It is stable to use elastic link bar.</p>
