ObjectiveTo compare the effectiveness of lateral approach minimally invasive plate osteosynthesis (MIPO) and helical plate MIPO in the treatment of proximal humeral shaft fractures. Methods The clinical data of patients with proximal humeral shaft fractures who underwent MIPO via lateral approach (group A, 25 cases) and MIPO with helical plate (group B, 30 cases) between December 2009 and April 2021 were retrospectively analyzed. There was no significant difference in gender, age, injured side, cause of injury, American Orthopaedic Trauma Association (OTA) fracture classification, and time from fracture to operation between the two groups (P>0.05). The operation time, intraoperative blood loss, fluoroscopy times, and complications were compared between two groups. The angular deformity and the fracture healing were evaluated according to anteroposterior and lateral X-ray films postoperatively. The modified University of California Los Angeles (UCLA) score for shoulder and the Mayo Elbow Performance (MEP) score for elbow were analyzed at last follow-up. Results The operation time in group A was significantly shorter than that in group B (P<0.05). However, the intraoperative blood loss and fluoroscopy times presented no significant difference between the two groups (P>0.05). All patients were followed up 12-90 months, with an average of 19.4 months. There was no significant difference in follow-up time between the two groups (P>0.05). In terms of the quality of postoperative fracture reduction, there were 4 (16.0%) and 11 (36.7%) patients with angulation deformity in group A and group B, respectively, and there was no significant difference in the incidence of angulation deformity (χ2=2.936, P=0.087). All fractures achieved bony union, there was no significant difference in fracture healing time between group A and group B (P>0.05); delayed union occurred in 2 cases and 1 case in group A and group B, respectively (healing time was 30, 42, and 36 weeks after operation, respectively). In group A and group B, 1 patient had superficial infection of incision, respectively; 2 patients and 1 patient had subacromial impact after operation, respectively; and 3 patients in group A had symptoms of radial nerve paralysis of different degrees; all of them were cured after symptomatic treatment. The overall complication incidence of group A (32%) was significantly higher than that of group B (10%) (χ2=4.125, P=0.042). At last follow-up, there was no significant difference in the modified UCLA score and MEPs score between the two groups (P>0.05). Conclusion Both lateral approach MIPO and helical plate MIPO can achieve satisfied effectiveness in the treatment of proximal humeral shaft fractures. Lateral approach MIPO may be beneficial to shorten the operation time, while the overall complication incidence of helical plate MIPO is lower.
Thirty patients of primary cholangiolithiasis were treated by the use of a rigid choledochoscope passing through the left lateral liver lobe for removal. 20 cases of them were manipulated with mini-incisions, the stones in 14 patients (70.0%) were completely removed. In the remaining 10 cases of conventional laparotomy, left lateral liver incised in 4, left lateral lobectomy in 6 before rigid choledochoscopic lithotomy; the stons were completely removed in eight patients (80.0%). No case had complications, the short-term effect of the method is obviously better than that of other various operative treatments. It has the advantages of less trauma, less pain, and quick recovery. It is a economical and effective new technique and has prospects of application.

Methods A total of 217 patients who underwent PCI from April 2007 to May 2009 were randomly divided into Perclose ProGlide group (105 patients, hemostasis by Perclose ProGlide Suture-Mediated Closure System) and control group (112 patients, hemostasis by compression). The Lower-limb braking time and the complications were recorded and analyzed. Results The successful rate was 98.1% (103 patients) in Perclose ProGlide group, and 100% (112 patients) in the control group; the difference between the two groups was not significant (Pgt;0.05). But there was a significant difference (Plt;0.01) in Lower-limb braking time between the two groups[(4.1±1.2) and (25±3.1) hours]. The post-operative complications between the two groups didn’t differ much. Conclusions Perclose ProGlide Suture-Mediated Closure System is a safe,effective and simple method after percutaneous coronary intervention to achieve immediate hemastasis. Skillfully processing may reduce the vascular complications.
Objective To investigate the prel iminary effectiveness of percutaneous kyphoplasty (PKP) in treating vertebral compressive fractures in patients with osteoporosis. Methods Between February 2008 and June 2010, 31 cases (31vertebrae) of osteoporotic vertebral compressive fractures were treated with PKP. Of 31 cases, 10 were male and 21 were female, aged from 64 to 80 years (mean, 70.7 years). All fractures were caused by mild trauma with an disease duration of 1-13 days. Affected vertebrae included T12 in 8 cases, L1 in 9 cases, L2 in 12 cases, and L4 in 2 cases. The effectiveness was evaluated with visual analogue scale (VAS), the Cobb’s angle, and the anterior vertebral height. Results The operation was completed successfully in all cases, without serious postoperative complication. Cement leakage occurred in 11 cases (35.5%), including 3 cases at the anterior vertebral edge, 4 cases at the lateral vertebra, and 4 cases at the puncture tunnel. All the cases were followed up 6-15 months (mean, 11 months). The mean fracture healing time was 11.5 weeks (range, 8-12 weeks). VAS score was decreased from 8.1 ± 1.2 preoperatively to 2.5 ± 0.6 at 3 months postoperatively and to 2.3 ± 0.8 at last follow-up; the Cobb’s angle was improved from (30.2 ± 5.3)° to (21.3 ± 3.6)° and (23.5 ± 3.8)° respectively; and the anterior vertebral height was increased from (13.98 ± 4.62) mmto (22.03 ± 4.93) mm and (22.56 ± 4.34) mm respectively. There were significant differences in VAS, the Cobb’s angle, and the anterior vertebral height between pre- and post-operation (P lt; 0.05), but there was no significant difference between 3 months postoperatively and last follow-up (P gt; 0.05). Conclusion PKP is effective for osteoporotic vertebral compressive fractures, which can rel ieve pain effectively, correct kyphosis, and prevent collapse of vertebra.
ObjectiveTo compare the clinical efficacy and safety between percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral compression fracture (OVCF) with intravertebral vacuum cleft (IVC). MethodsBetween January 2010 and December 2013, 68 patients with single OVCF and IVC were treated, and the clinical data were retrospectively analyzed. Of 68 patients, 48 underwent PVP (PVP group) and 20 underwent PKP (PKP group). There was no significant difference in age, gender, disease duration, fracture level, bone mineral density (BMD), visual analogue scale (VAS), Oswestry disability index (ODI), and preoperative radiological parameters between 2 groups (P > 0.05). The intraoperative incidence of cement leakage, cement volume, and operative time were compared between 2 groups; VAS score was used for evaluation of back pain and ODI for evaluation of dysfunction; the incidence of adjacent vertebral fracture was observed within 2 years. The vertebral height and kyphotic angle were measured on X-ray films; the rate of vertebral compression (CR), reduction rate (RR), progressive height loss (PHL), reduction angle (RA), and progressive angle (PA) were calculated. ResultsThere was no significant difference in cement volume and the incidence of cement leakage between 2 groups (P > 0.05). The operative time in PVP group was shorter than that in PKP group, showing significant difference (t=-8.821, P=0.000). The mean follow-up time was 2.4 years (range, 2.0-3.1 years). The VAS scores and ODI were significantly reduced at 1 day, 1 year, and 2 years after operation when compared with preoperative scores (P < 0.05), but there was no significant difference between different time points after operation in 2 groups (P > 0.05). Adjacent vertebral fracture occurred in 5 cases (10.4%) of PVP group and in 2 cases (10.0%) of PKP group, showing no significant difference (χ2=0.003, P=0.963). BMD was significantly increased at 1 year and 2 years after operation when compared with preoperative BMD (P < 0.05), but no significant difference was found between 2 groups (t=0.463, P=0.642; t=0.465, P=0.646). The X-ray films showed that CR and kyphotic angle were significantly restored at immediate after operation in 2 groups (P < 0.05); but vertebral height and kyphotic angle gradually aggravated with time, showing significant difference between at immediate and at 1 and 2 years after operation (P < 0.05); there was no significant difference in CR and kyphotic angle between 2 groups at each time point (P > 0.05). RR, RA, PHL, and PA showed no significant difference between 2 groups (P > 0.05). ConclusionThere is similar clinical and radiological efficacy between PVP and PKP for treatment of OVCF with IVC. Re-collapse could happen after operation, so strict observation and follow-up are needed.
ObjectiveTo explore the impact of different tracts on the effectiveness and safety of percutaneous nephrolithotomy (PCNL) on complete staghorn calculus.MethodsPatients with complete staghorn calculus who underwent single channel PCNL by the same surgeon in West China Hospital of Sichuan University from October 2009 to August 2019 were included. The removing time, the rate of immediate stone removal, the average extubating time, and the incidences of postoperate complications such as fever and bleeding were analyzed statistically.ResultsA total of 379 patients were included. There were 146 cases in the upper tract group, 170 cases in the lower tract group and 63 cases in the middle tract group. Compared with the upper and middle tract groups, the lower tract group had shorter stone removing time [(50.34±18.52) vs. (53.41±22.75) vs. (41.79±17.45) min, P<0.001], shorter average extubating time [(5.53±1.83) vs. (6.17±1.44) vs. (4.96±1.91) d, P=0.007]. The rate of immediate stone removal was higher in the the upper tract group (40.56% vs. 32.79% vs. 34.71% ), but there was no statistical difference among the three groups (P=0.447). There was no significant difference among the three groups in the fever incidence (25.44% vs. 24.24% vs. 26.85%, P=0.938) or bleeding incidence (3.54% vs. 3.03% vs. 4.03%, P=1.000). In addition, there were 8 cases of pleural injury in the upper tract group.ConclusionsCompared with the lower and middle tract, PCNL with upper tract has a higher rate of removing stones for complete staghorn calculus, but there was no significant difference among the three groups. The incidences of bleeding and fever after surgery are similar in the three groups, but the risk of pleural injury may be increased in the upper tract group.
ObjectiveTo compare the effectiveness of robot assisted and C-arm assisted percutaneous kyphoplasty (PKP) in the treatment of single/double-segment osteoporotic vertebral compression fracture (OVCF).MethodsThe clinical data of 108 cases of single/double-segment OVCF who met the selection criteria between May 2018 and October 2019 were retrospectively analyzed. There were 65 cases of single-segment fractures, of which 38 cases underwent “TiRobot” orthopedic robot-assisted PKP (robot group), 27 cases underwent C-arm X-ray machine fluoroscopy-assisted PKP (C-arm group). There were 43 cases of double-segment fractures, including 21 cases in robot group and 22 cases in C-arm group. There was no significant difference in gender, age, T value of bone mineral density, fracture segment distribution, time from injury to operation, and preoperative visual analogue scale (VAS) score, vertebral kyphosis angle (VKA), and height of fractured vertebra (HFV) in the patients with single/double-segments fractures between robot group and C-arm group (P>0.05). The operation time, the fluoroscopy frequency of the surgeons and the patient, the fluoroscopy exposure time of the surgeons and the patient, the radiation dose of the C-arm; the VAS scores, VKA, HFV before operation, at 1 day and 6 months after operation; and the complications in the two groups were recorded and compared.ResultsAll patients underwent surgery successfully. The operation time of the single-segment robot group was significantly longer than that of the C-arm group (t=5.514, P=0.000), while the operation time of the double-segment robot group was not significantly different from that of the C-arm group (t=1.892, P=0.205). The single/double-segment robot group required three-dimensional scanning, so the fluoroscopy frequency, fluoroscopy exposure time, and radiation dose of C-arm received by the patient were significantly higher than those of the C-arm group (P<0.05); the fluoroscopy frequency and the fluoroscopy exposure time received by the surgeons were significantly less than those of the C-arm group (P<0.05). There was no infection, embolism, neurological injury, and adjacent segmental fractures. The single/double-segment robot group showed lower rate of cement leakage when compared with the C-arm group (P<0.05), all the cases of cement leakage happened outside the spinal canal. The VAS score, VKA, and HFV of the single/double-segment robot group and the C-arm group were significantly improved at 1 day and 6 months after operation (P<0.05), and the VAS score at 6 months after operation was further improved compared with that at 1 day after operation (P<0.05). At 1 day and 6 months after operation, there was no significant difference in VAS score between the single/double-segment robot group and the C-arm group (P>0.05). The VKA and HFV of robot group were significantly better than those of the C-arm group (P<0.05).ConclusionFor single/double-segment OVCF, robot assisted PKP has more advantages in correcting VKA and HFV, reducing fluoroscopy exposure of surgeons and bone cement leakage rate; C-arm assisted PKP has more advantages in reducing the operation time of single-segment OVCF and fluoroscopy exposure of patients during operation.
