ABSTRACT

Objective:To evaluate the safety and efficacy of one-stage posterior-only jumping hemivertebra (HV) resection combined with respective short fusions in the treatment of congenital scoliosis (CS) caused by multiple HVs.Methods:All of 13 consecutive patients with multiple HVs treated surgically from January 2010 to December 2017 were retrospectively reviewed, including 4 males and 9 females with a mean age of 3.7±1.2 years. One child had 4 HVs, and the rest had 2 HVs. The responsible HVs causing local scoliosis/kyphosis deformity or coronal plane deviation were selected as the target of resection. The distal HV was removed firstly and then the proximal one was resected; both of the fixation vertebraes were horizontalized during surgery. The clinical and imaging data of the children before the initial operation, immediately after the operation and at the latest follow-up were collected, and the short-term and long-term complications related to surgery were recorded. The data were evaluated on the whole-standing spine anteroposterior and lateral films, including the corrections of proximal and distal main curves, coronal balance, local kyphosis, and the improvement of spinal growth height (upper and lower internal fixation length, T 1-S 1 length). At the same time, the re-progression of coronal and sagittal deformities of the spine during growth was recorded (coronal decompensation: emerging postoperative curve progression more than 20°; kyphosis progression: kyphosis aggravation between upper and lower internal fixation more than 40°) and internal-fixation-related complications (screw cutting, screw malposition) were recorded. Results:Dual HVs were resected in each child, of which 8 (61.5%) were located on contralateral side of the spine, and 5 (38.5%) were located on ipsilateral side of the spine. The follow-up time was 6.2±3.3 years (range 2.0-10.5 years) after surgery. The Cobb angles of proximal and distal main curves were 36.7°±11.8° and 35.2°±7.8° respectively before surgery and were corrected to 9.7°±6.6° and 6.1°±4.1° respectively after surgery ( F=31.249, F=93.83, P< 0.001) ( t=6.888, t=10.954, P<0.001), and the correction rates was 73.6%±19.6% and 82.7%±11.7%, respectively. They were maintained at 14.3°±5.4° and 8.0°±4.6° at the latest follow-up, showing the correction rates loss of 15.8%±26.9% and 6.9%±7%, respectively. The coronal balance improved from 17.2±14.8 mm pre-operatively to -0.2±15.7 mm postoperatively ( t=2.703, P=0.008), and it remained at 0±18.4 mm at the final follow-up ( F=4.137, P=0.024). The T 1-S 1 length was corrected to 273.8±27.3 mm postoperatively, slightly increased compared with pre-operation 256.3±24.0 mm, ( t=0.680, P=0.527), and significantly increased to 333.2±33.4 mm at the latest follow-up ( t=2.986, P<0.001; F=6.704, P=0.003). Seven patients had local kyphosis before operation, which was significantly improved from 32.2°±13.6° to 6.1°±9.8° with a correction rate of 93.4%±27.0% after surgery ( t=3.355, P=0.004), which showed no significant loss of correction at the latest follow-up (5.4°±10.4°) ( F=11.187, P=0.002). Six patients (46.2%) developed coronal decompensation (Curve magnitude >20 °), with an average of 21.7°±1.9°. Two cases (15.4%) had progressive kyphosis between the thoracic regional internal fixations at 3 months after surgery, which were 68° and 58° respectively. After bracing, both coronal decompensation and sagittal kyphosis were improved. At the last follow-up, the coronal decompensation was improved to 14.7±8.9° and the kyphosis was alleviated to 55° and 46°, respectively. Conclusion:Posterior-only skipping hemivertebra resection and short fusion is a safe, effective procedure yielding significantly improvement of the growth imbalance and reginal spinal deformities of CS with multiple HVs. The mid-term follow-up results showed that the progress of the scoliosis was common during the growth period, which could be further controlled by supplementary brace treatment.

ABSTRACT

Objective:To investigate the association of the cross-sectional area of lumbar paraspinal muscle with the spino-pelvic profile based on Roussouly classification.Methods:From January 2019 to December 2019, 102 patients with lumbar disc herniation were collected, the index level included L 2, 3 in 3 cases(2.9%), L 3, 4 in 14 cases(13.7%), L 4,5 in 58 cases (56.9%), and L 5S 1 in 27 cases (23.5%). According to Roussouly classification, there were 29 cases of type I (28.4%), aged 57.0±11.7 years old (range 43 to 72 years old), 31 of type II (30.4%), aged 56.9±10.3 years old (range 40 to 70 years old), 28 of type III (27.5%), aged 53.5±12.9 years old (range 42 to 70 years old), and 14 of type IV (13.7%), aged 59.7±9.5 years old (range 51 to 70 years old). The clinical status of the patients were evaluated with the MOS 36-item short-form health survey (SF-36), Oswestry disability index (ODI) and visual analog scale (VAS). Select all patients with L 1, 2, L 2, 3, L 3, 4, L 4, 5 and L 5S 1 disc level axial MRI images, to measure the cross-sectional area (CSA) of paraspinal muscles (back extensor muscle and psoas muscle) and the CSA of intervertebral disc at each disc level, and calculate the relative cross-sectional area (RCSA: the ratio of the CSA of muscles to that of the disc at the same level). One-way ANOVA was used to test the RCSA of the paraspinal muscles of the four groups, and then LSD- t test was used for pair wise comparisons to compare the RCSA of the paraspinal muscles in each group. Results:There was no significant difference in age ( F=1.067, P=0.367), female/male sex ratio ( χ2=2.412, P=0.491) and body mass index ( F=0.326, P=0.481). Roussouly type I group showed lower SF-36 score in both SF-36 PCS (31.5±6.5, F=3.207, P=0.047) and SF-36 MCS (33.9±5.7, F=3.409, P=0.031) compared with the other three types. In contrast, there were no significant differences in VAS Back Pain ( F=0.140, P>0.05), VAS leg pain ( F=0.622, P>0.05). and ODI scores ( F=1.075, P>0.05) among the types. At each level from L 1, 2 to L 5S 1, the RCSA of psoas muscle in Roussouly type IV (19.18±6.98, 35.36±10.37, 41.25±14.35, 61.58±12.03, 59.29±11.73) was significantly lower than that in patients with any other Roussouly type ( P<0.05), while no significant difference in the psoas RCSA among type I, type II and type III curves ( P>0.05). With regards to back extensor muscle, the RCSAs of back extensor muscle in Roussouly types I (135.32±19.86, 138.53±22.92, 125.06±21.44, 122.40±19.69, 110.87±18.08) and II (131.30±18.68, 136.39±24.87, 122.61±22.52, 121.10±20.47, 107.46±18.29) were significantly lower than those in Roussouly type III and IV at each level ( P<0.05), yet no significant difference between type I and II or between type III and IV. The ratio between the RCSA of back extensor muscle and psoas muscle in four types increased gradually from L 1, 2 to L 5S 1, with that being higher in type II (0.20±0.07, 0.33±0.09, 0.40±0.13, 0.58±0.11, 0.65±0.08) and lower in type IV (0.13±0.05, 0.24±0.07, 0.31±0.10, 0.47±0.10, 0.52±0.11). Conclusion:RCSA of paraspinal muscles varied among Roussouly types, suggesting a significant association between paraspinal muscles and the sagittal spino-pelvic alignment. Sagittal spino-pelvic alignment may be involved in the degeneration of paraspinal muscles.

ABSTRACT

Objective:To explore the efficacy and correction mechanism of posterior column osteotomy for treatment of "Lenke 5-like" lumbar congenital scoliosis.Methods:From April 2008 to September 2019, 16 patients with lumbar congenital scoliosis underwent posterior column osteotomy were retrospectively reviewed including 6 males and 10 females, aged 23.9±11.7 years (range, 14-48 years). Among them, 8 cases were unsegmentation, 5 malformation and 3 mixed type. The average segments of PCO were 5.3. Posterior column osteotomy was adapted after the insertion of pedicle screws, then removed spinous process, ligaments, superior and inferior facet and corrected the deformity with the rods. The pre- and post-operative and last follow-up radiographic parameters were measured: Cobb angle of lumbar curve, distance between C 7 plumbline and center sacral vertical line (C7PL-CSVL), deformity angle (DA), disc correction angle (DCA) of instrumented segments, disc angle above upper instrumented vertebra (DAAU), lower instrumented vertebra disc angle (LDA), upper instrumented vertebra slope (US), lower instrumented vertebra slope (LS), lower instrumented vertebra offset (LO) and sagittal parameters such as thoracic kyphosis (TK), lumbar lordosis(LL) and thoracic junctional kyphosis (TJK). The Scoliosis Research Society-22 questionnaire (SRS-22) were conducted at preoperation and the final follow up to evaluate the clinical outcomes. Results:The mean follow-up period was 16.69±7.65 months (range, 12-36 months). The coronal DA was 26.74°±10.59° while the sagittal DA was 14.70°±11.63°. The pre- and post-operative Cobb angle were 51.19°±12.91° and 23.25°±12.86° while the correction rate was 57.17%±16.31% and reached 24.26°±13.19° in the last follow-up. The improvement of DAAU, LDA, US, LS, and LO pre- and post-operative had statistical significance ( P<0.001). The pre- and post-operative and the last follow-up C 7PL-CSVL were 27.13±17.08 mm, 21.81±12.80 mm and 20.24±15.02 mm. The pre-operative, postoperative and last follow-up DAAU were -4.35°±2.12°, 1.36°±2.34° and 1.60°±2.45°. The pre- and post-operative LDA were -7.03°±4.40° and 2.42°±3.39°, and the last follow-up LDA was 2.81°±2.98°. US and LS decreased from pre-operative 12.01°±8.33° and 21.46°±5.79° to 2.84°±7.52° and 11.64°±6.06°. The mean US and LS were 4.22°±6.56° and 11.56°±6.02° in the last follow-up. LO decreased after surgery and keep unchanged in the last follow-up, which were 12.71°±6.43°, 6.31°±5.17° and 7.01°±4.73°, respectively. For the sagittal plane parameters, the changes of TK, LL, and TJK reached statistical significance through the surgery. LL increased from 33.69°±14.01° to 44.28°±10.07° through the surgery and reached 41.97°±6.69° at the last follow-up while TK increased from 13.41°±12.37° to 23.52°±8.10°, TJK decreased from 29.02°±20.74° to 16.20°±12.62° after the surgery and reached 16.07°±13.33° at the last follow-up. The pre-operative, post-operative and last follow-up thoracic kyphosis were 13.41°±12.37°, 23.52°± 8.10°, and 24.21°±7.39°. There was no statistical significance of the change of C 7PL-CSVL, SVA, SSA and PI-LL through the surgery ( P>0.05). At the final follow-up, the self-image and psychologic status scores of SRS-22 were significantly higher than that before surgery ( t=15.457, P<0.001; t=14.726, P<0.001), and there was no significant difference in the rest of the domain ( P>0.05). Conclusion:"Lenke5-like" lumbar congenital scoliosis could obtain satisfactory correction of coronal and sagittal deformities with the treatment of posterior column osteotomy, while there was no significant loss of correction during follow-up. The incidence of surgical complications is low.

ABSTRACT

Objective:To evaluate the outcomes of transforaminal lumbar interbody fusion (TLIF) for patients with lumbar spinal stenosis (LSS) and diffuse idiopathic skeletal hyperostosis (DISH).Methods:This study recruited 33 patients (15 male and 18 female) with LSS and DISH who underwent TLIF surgery from January 2010 to July 2018. The mean age was 65.1±11.2 years old and the instrumented segments averaged 1.45±0.42 levels. Another group of LSS patients without DISH were well matched to the DISH group at a 1∶1 ratio in terms of age, sex, and instrumented levels. Lumbar lordosis, local lordosis as well as lowerlumbarlordosis were measured on X-ray taken before and after surgery. According to Pfirrmann's classification, the degree of preoperative disc degeneration was evaluated on preoperative MRI, and the incidence of postoperative fusion cage subsidence was recorded during follow-up. Oswestry disability index (ODI) was used to evaluate the lumbar function and visual analogue scale(VAS) scores for low back pain and leg pain were used to evaluate the quality of life.Results:There were no significant difference between two groups in terms of age, bone mineral density, operative time, postoperative bleeding volume, fusion levels and postoperative follow-up time. Compared with the non-DISH group (3.20±0.95), the DISH group had higher degeneration disc according to Pfirrmann's classification (3.82±0.64) ( t=3.109, P=0.002), lower lumbar lordosis(37.4°±8.5° vs. 45.2°±12.2°, t=3.013, P=0.003), and lower lower lumbar lordosis (18.3°±3.9° vs. 21.9°±5.4°, t=3.104, P=0.002). After TLIF surgery, lumbar lordosis was significantly improved in both groups. During follow-up, notable correction loss was noted in DISH group in terms of lumbar lordosis (43.6°±9.7° vs. 50.1°±10.2°, t=2.652, P=0.010), lower lumbar lordosis (19.1°±4.7° vs. 22.9°±5.2°, t=2.540, P=0.013) as well as local lumbar lordosis (17.4°±6.5° vs. 22.7°±7.2°, t=3.138, P=0.002). Moreover, these above value in the DISH group were significantly lower than those in the non-DISH group. At the latest follow-up, 12 patients in the DISH group were identified with cage subsidence, which were significantly higher than in the non-DISH group (36.3% vs. 12.1%, χ2=5.280, P=0.022). Till the latest follow-up, both groups had considerable improvement of the ODI score, back pain and leg pain VAS score. However, the back pain VAS scores in the DISH group were significantly higher than that in the non-DISH group ( t=2.862, P=0.005). Conclusion:Compared with LSS patients without DISH, LSS patients with DISH are more likely to have cage subsidence and loss of correction of lumbar lordosis angle after TLIF surgery. Moreover, the VAS score of low back pain in LSS patients with DISH was lower than those without DISH.

ABSTRACT

Objective:To analyze the factors which may influence postoperative early ambulation in patients with fresh fracture so as to further optimize the perioperative protocol based on the concept of enhanced recovery after surgery (ERAS).Methods:A retrospective analysis was conducted of the patients who had been treated for a single fresh fracture at the extremity, pelvis or acetabulum from May 2019 to July 2019. Collected were the data concerning basic features of patients, perioperative ERAS management and surgery, as well as early ambulation on the day of surgery or the first day after surgery. The patients were divided into an early ambulation group and a non-early ambulation group according to the time of ambulation. Statistical analyses were performed of the relationships between early ambulation and 20 potential factors concerning basic features of patients, perioperative ERAS management and surgery. Logistic correlation analysis was performed to identify risk factors for postoperative early ambulation.Results:A total of 306 patients were included, including 96 upper limb, 203 lower limb, 5 acetabular and 2 pelvic fractures. Of them, 150 ambulaed from bed on the day of surgery or the first day after surgery while 156 did not. Significant differences were observed between the 2 groups in fracture site, intake of carbohydrate liquids the night before surgery and the day of surgery, catheter indwelling, intraoperative liquid transfusion volume and postoperative complications ( P < 0.05). Logistic correlation analysis of the relationship between the above factors and postoperative early ambulation found that fracture site and intraoperative liquid transfusion volume were significantly correlated with postoperative early ambulation ( P < 0.05). Conclusions:About half of the patients with a single fresh fracture may ambulate early after surgery. Fracture site and intraoperative liquid transfusion volume may be significantly correlated with postoperative early ambulation.

ABSTRACT

Objective:To compare the perioperative data between the pararectus and ilioinguinal approaches in the internal fixation of acetabular fractures.Methods:A randomized controlled trial was conducted to enroll 74 patients with acetabular fracture who were admitted to Department of Orthopaedic Trauma, Beijing Jishuitan Hospital from June 2018 to January 2021. They were randomly divided into 2 groups. In group A of 37 cases, there were 28 males and 9 females with an age of (55.8±15.2) years, and 10 anterior column fractures, 7 anterior+posterior hemi-transverse fractures, one transverse fracture, 3 T-shaped fractures and 16 both column fractures according to Letournel-Judet classification. In group B of 37 cases, there were 28 males and 9 females with an age of (49.4±14.6) years, and 8 anterior column fractures, 6 anterior+ posterior hemi-transverse fractures, 2 transverse fractures, 2 T-shaped fractures and 19 both column fractures according to Letournel-Judet classification. Group A was subjected to open reduction and plate fixation via the pararectus approach while group B to open reduction and plate fixation via the ilioinguinal approach. The 2 groups were compared in terms of operation time, intraoperative blood loss, postoperative reduction and perioperative complications.Results:There were no significant differences in baseline data between the 2 groups, showing comparability between them ( P>0.05). The operation time in group A [150 (120, 180) min] was significantly shorter than that in group B [180 (150, 225) min] ( P<0.05). There were no significance differences between the 2 groups in intraoperative blood loss [800 (600, 1, 000) mL versus 1, 000(600, 1, 300) mL], rate of good to excellent reduction [91.9%(34/37) versus 78.4%(29/37)], or incidence of complications [24.3%(9/37) versus 45.9%(17/37)] ( P>0.05). Conclusion:Compared with the ilioinguinal approach, the pararectus approach can reduce operation time significantly in the internal fixation of acetabular fractures.

ABSTRACT

Objective:To evaluate the radiographic and clinical outcomes of pre-operative Halo-gravity traction (HGT) and posterior correction surgery in treating patients with neurological deficits secondary to severe focal angular kyphosis of the upper thoracic spine.Methods:A total of 16 patients (11 males, 5 females) with neurologic deficits secondary to severe focal angular kyphosis of the upper thoracic spine undergoing preoperative HGT and posterior correction operation from January 2010 to December 2019 were retrospectively analyzed. The average age was 12.9±5.6 years (range 6-27 years). The standing X-ray of whole spine was taken at pre-, post-traction and post-operation. The Cobb angles of main curve at both sagittal and coronal planes were measured accordingly. The neurologic function at pre-traction, post-traction and post-operation was assessed according to the American Spinal Injury Association (ASIA) grading. The complications during HGT, operation and post-operative follow-up were recorded for each patient.Results:The average values of focal kyphosis and scoliosis were 96.1°±16.0° (71°-128°) and 75.5°±20.5° (40°-107°) at pre-traction respectively. The spinal cord function graded by ASIA criteria at pre-traction was B in 1 patient, C in 6 and D in 9, respectively. The correction rates of focal kyphosis and scoliosis were 32.8%±15.0% (18.0%-65.9%) and 22.9%±8.0% (14.1%-38.6%) after traction, which were further improved to 45.4%±14.9% (29.0%-69.0%) and 33.6%±8.6% (23.3%-49.3%) at post-operation without significant correction loss during 35.6±14.2 (24-72) months follow-up. After traction, the spinal cord function improved to grade D in 4 patients and grade E in 12 patients. At the last follow-up, the spinal cord functions were grade E in 15 patients and grade C in 1 patient. No neurologic monitor events occurred during operation. One patient suffered from transient left brachial plexus after operation. Further, proximal hook loosening was observed in 2 patients during follow-up. The spinal cord function was ASIA grade C pre-operatively in one patient, who recovered to ASIA grade E after operation and significantly deteriorated to ASIA C at 4 years follow-up.Conclusion:The correction of spinal kyphoscoliosis was satisfactory in this cohort. Preoperative HGT followed by posterior spinal correction surgery is an effective and safe procedure in treating neurological deficits secondary to focal angular kyphosis in the upper thoracic spine.

ABSTRACT

Objective:To investigate the outcome of posterior correction surgery for severe kyphoscoliosis secondary to spinal Gorham disease, further to explore the countermeasure in such complicated condition.Methods:From January 2005 to December 2019, a total of 12 consecutive patients were diagnosed with spinal Gorham disease. Four patients who had undergone correction surgery were reviewed retrospectively. There were 3 males and 1 female. The median age of surgery was 14.5 years (11.5 years, 27.5 years), with the median of Cobb angle of scoliosis and kyphosis 29° (21.5°, 78.0°) and 94° (78.0°, 103.0°), respectively. After Halo-gravity traction, one-stage posterior correction surgeryand Schwab grade I or II osteotomy, with pedicle screw fixation bridging the diseased vertebrae was performed. Drug therapy of bisphosphonate was recommended after surgery. The Cobb angle of scoliosis and kyphosis, coronal and sagittal balance were measured on the standing upright radiographs of the spine. CT and MRI were used to give precise evaluation of spinal and peripheral soft tissue involvement.Results:After Halo-gravity traction of 3 months (2.5 months, 3.5 months), the median of Cobb angle of scoliosis decreased to 23.5° (15.5°, 77.0°) and kyphosis decreased to 65° (57°, 83.5°) respectively. Two patients underwent facetectomyand 2 received Ponte osteotomy. The median operative time and blood loss were 5.5 h (5.1 h, 5.9 h) and 3 095ml (2 950 ml, 3 320 ml), with the fusion segment of 13.5 (12.5, 14.5) and the fixation density of 47.8% (40.9%, 57.3%). After surgery, the median of Cobb angle of scoliosis and kyphosis decreased to 18° (10.5°, 38.5°) and 59° (42.0°, 78.0°). Compared to the values before traction, the median of correction rates of scoliosis and kyphosis after surgery were 46.7% (33.1%, 59.5%) and 35% (12.3%, 51.1%) respectively. Moreover, the median of coronal balance decreased from 15.5 mm (9.0 mm, 21.0 mm) to 6.5 mm (4.0 mm, 9.0 mm), while the median of sagittal balance decreased from 14 mm (-18.0 mm, 27.5 mm) to 5.5 mm (-5.5 mm, 12.5 mm). During a median of follow-up of 2.8 years (2.0 years, 3.5 years), no complication was detected except one patient whounderwent revision surgery for rod broken.Conclusion:One-stage posterior correction surgery combined with preoperative halo-gravity tractionand postoperative anti-osteoporosis therapydemonstratedto be safe and effective for severe kyphoscoliosis secondary to spinal Gorham disease. More attention should be paid to the failure of internal fixation after surgery.

ABSTRACT

Objective:To compare the incidence of intraoperative neurological complications during correction surgery of spinal deformities in patients with or without rotatory subluxation (RS), and to analyze the correlation between RS and intraoperative neurological complications.Methods:From January 2012 to August 2017, a total of 37 patients with RS undergoing correction surgery, whom was excluded with preoperative spinal traction or three-column osteotomy during operation were retrospectively reviewedin our hospital. Thirty-seven patients without RS undergoing correction surgery were included asthe control group. The radiographic parameters included Cobb angle of main curve, coronal trunk balance (CTB) which was the distance between C 7 plumb line and center sacral vertical line, global kyphosis (GK), sagittal vertical axis (SVA), RS at coronal plane (CRS), RS at sagittal plane (SRS) and axial rotation (AR). The abnormal intraoperative neurophysiological monitoring events and positive wake-up test were recorded. Results:The mean age was 42.4±17.9 years (12-74 years) in the RS group and 42.7±18.3 years (12-74 years) in the control group( t=0.0713, P=0.943). The mean preoperative Cobb angle of main curve, CTB, GK, and SVA was 75.4°±29.7°, 38.4±28.4 mm, 52.8°±25.2°, and 40.3±36.8 mm respectively in the RS group, which was 75.1°±27.6°( t=0.045, P=0.964), 34.8±24.4 mm( t=0.584, P=0.560), 49.8°±22.5°( t=0.540, P=0.591), and 38.7±25.3 mm ( t=0.219, P=0.828) respectively in the control group. There was no significant difference between the two groups among the above preoperative index. Significant improvements in Cobb angle of main curve, CTB, GK, SVA,CRS, SRS and ARA were found between preoperation and postoperation ( P<0.05 for all), while no significant correction loss was observed during follow-up ( P>0.05 for all). There were 6 patients (16.2%) in the RS group and 4 patients (10.8%) in the control group with preoperative neurological deficit of Frankel grade D ( F=0.463, P=0.496). The abnormal intraoperative neurophysiological monitoring events were observed in 5 patients (13.5%) of the RS group and 1 patient (2.7%) of the control group ( F=2.902, P=0.088). Positive wake-up test was found in 2 patients of RS group (5.4%) ( F=2.056, P=0.493). Conclusion:Patients with RS had higher risks of preoperative neurological deficit, abnormal intraoperative neurophysiological monitoring events and deteriorative neurological deficit at postoperation. The RS at preoperation may be a risk factor for intraoperative neurological deficit.

ABSTRACT

Objective:To investigate the incidence and management of deep surgical site infection(SSI) after the spinal deformity surgery.Methods:This study retrospectively reviewed a consecutive cohort of 8818 patients with spinal deformity who received spinal deformity surgery between January1998 and December 2017 at our center. The diagnosis of deep SSI was based on the clinical symptoms, imaging data and laboratory findings. Early infection and late infection were defined as deep infections occurring <3 months and >3 months after the initial procedure, respectively. All deep SSIs were first treated with irrigation and debridement, closed suction irrigation system and antibiotics. If the infection cannot be eradicated, dressing change is recommended within 2 years after the initial surgery. The instrumentation can be removed 2 years after the initial surgery with careful evaluation of the fusion mass. The posterior-anterior and lateral radiographs were used to measure the coronal parameters and sagittal alignment.Results:Sixty patients were diagnosed as deep SSI after spinal deformity surgery, including 11 patients with early infection and 49 patients with late infection. No significant difference was observed in terms of age, gender ratio, surgical approach and fusion levels between the two groups. Deep SSI seemed to be more likely to occur between 2 and 5 years after surgery. Incidence of SSI was lowest in the patients with idiopathic scoliosis and ankylosing spondylitis, and highest in the patients with neuromuscular and syndromic scoliosis. There was a high rate of negative culture in the primary culture. Staphylococcus aureus and Escherichia coli were the most common organisms in the early infection, while patients with late infection had a high rate of low-virulent skin flora. In the early infection group, nine patients retained instrumentation while the implants were removed 2 years after the primary surgery in 2 patients. In patients with late infection, instrumentation was retained in 5 cases and removed in 10 cases until 2 years after the primary surgery. 34 cases were infected 2 years after the primary surgery and the implants were removed directly. One patient underwent reoperation with instrumentation 1 month after implant removal, another patient underwent reoperation 3 years after implant removal due to progression of deformity. Significant loss of coronal correction was noted at the latest follow-up.Conclusion:The rate of deep SSI after spinal deformity surgery was 0.68%, of which the incidence of early infection and delayed infection was 0.12% and 0.56%, respectively. An increased risk of SSI in patients with neuromuscular and syndromic scoliosis was noted. If the infection cannot be eradicated after repeated debridement, we recommend instrumentation removal 2 years after the initial surgery, but there is still a high risk of loss of correction in these patients.

ABSTRACT

Objective:To evaluate long-term results of growth friendly non-fusion technique (GF) in the treatment of early-onset scoliosis (EOS).Methods:From August 2008 to October 2019, a total of 26 EOS patients (mean age 7.2±2.4 years old) who had completed surgery with GF treatment, including 12 males and 14 females, were reviewed retrospectively. Among them, 16 patients underwent growing rod treatment while 10 patients underwent vertical expandable prosthetic titanium rib (VEPTR) treatment. All patients had minimum 2 lengthening procedure during distraction period and over 2-year follow-up after graduation. Radiographic data were collected before and after index surgery as well as at graduation and the latest follow-up. Complications were also recorded during distraction period and after graduation.Results:A total of 145 lengthening procedures were performed in 26 patients, averagely 5.6 procedures per patient. The mean age at graduation was 12.6±1.6 years old. The average follow-up was 4.7±1.4 years duringdistraction period, and 2.9±0.9 years after graduation.The main Cobb angle was significantly decreased from 81.2°±17.3° to 41.1°±13.1°( t=8.124, P<0.001)after the index surgery, but slightly increased to 48.8°±15.4° at the end of distraction. After definitive spinal fusion, the main Cobb angle was notably decreased from 52.8°±16.1° to 45.4°±14.8° in 16 patients( t=2.415, P=0.035), with an average correction rate of 14.1%±9.4%. At the latest follow-up, the main Cobb angle was 45.2°±15.6° and the average correction rate was 44.3%±15.5% when comparing with the value before the index surgery. The thoracic and spinal height were significantly increased after initial surgery. During distraction period, the average gain of thoracic and spinal height was 3.3±0.9 cm and 5.6±1.9 cm, with the growth rate of 0.6±0.3 cm and 1.0±0.4 cm per distraction, respectively. A total of 36complications were recorded in 14 patients. There were 27 complications occurred during distraction period and 9 after graduation. Conclusion:Surgical management of EOS with growing rod and VEPTR could effectively correct the spinal deformity and maintain spinal growth. The complication rate after graduation was relative lower than distraction period. However, the correction of definitive spinal fusion during graduation was relative lower.

ABSTRACT

Objective: To observe the reversal and prevention effect of New Shengmai Decoction on the rats’ cardiomyocyte apoptosis induced by adriamycin, and provide the experimental foundation basis for the clinical treatment of myocardial injury induced by adriamycin. Method: The rat models with cardiomyocyte apoptosis were established by adriamycin. Forty male SD rats were divided randomly into four groups, including the normal group, the adriamycin model group, the captopril group and the New Shengmai Decoction group. During the experiment, the mental state, activity, feeding, hair color and other conditions of the rats were observed. After 6 weeks of treatment, the cardiac function and left ventricular hypertrophy of rats were measured and the pathological changes of myocardium were observed by HE staining. And the apoptosis of myocardial cells was observed by TUNEL staining and protein expressions of Caspase-3, Bcl-2, and Bax were detected by immunohistochemistry. Results: Compared with the control group, the cardiac function of the model group was significantly decreased. Compared with the model group, the cardiac function of rats after the different drugs’ treatment could be improved in the different degrees and the effect of the New Shengmai Decoction group was significant. Compared with the control group, the heart body ratio, left ventricular hypertrophy index and myocardial cell apoptosis index in the model group were all significantly increased. Compared with the model group, the captopril group and the New Shengmai Decoction group ameliorated cardiac hypertrophy and myocardial cell apoptosis in rats. Compared with the control group, the expression level of bcl-2 protein in the model group was decreased, while the expression level of Bax and Caspase-3 protein was increased. Compared with the model group, captopril and the New Shengmai Decoction increased the expression level of bcl-2 protein and decreased the expression level of Bax and Caspase-3 protein. Conclusion: The New Shengmai Decoction can improve the cardiac function and lessen cardiomyocyte apoptosis of rats. It can also decrease the expression of protein Caspase-3 in the cardiac muscle of rats or inhibit its activity. In order to restrain cardiomyocyte apoptosis, the New Shengmai Decoction can increase the expression of protein Bcl-2 and decrease the expression of protein Bax through improving the expression of Bcl-2/Bax in the cardiac muscle of rats.

ABSTRACT

Objective: To study the correlation between UPLC fingerprint of anti-inflammatory effect of active components from nonvolatile fraction of Blumea balsamifera, and to provide the basis for clarifying the anti-inflammatory material basis of B. balsamifera. Method: UPLC was used to establish fingerprint of nonvolatile fraction of 12 batches of B. balsamifera and their common fingerprint peaks were identified by UPLC-Q-TOF-MS.The corresponding pharmacodynamic data were obtained by auricle swelling and inflammation model mice induced by xylene, and spectrum-effect relationship was established by gray correlation analysis. Result: A total of 14 common peaks in nonvolatile fraction of B. balsamifera were established by UPLC fingerprint and 9 common peaks of them were identified.The correlation between UPLC fingerprint and the anti-inflammatory activity was from 0.717 1 to 0.550 5.The contribution of chemical compositions represented by each characteristic peak to the anti-inflammatory efficacy was in the order of peak 3 > peak 9 > peak 4 > peak 11 > peak 2 > peak 1 > peak 14 > peak 7 > peak 6 > peak 5 > peak 12 > peak 8 > peak 10 > peak 13, and the top two peaks with strong contribution to anti-inflammatory effect were peak 3 and peak 9, they were 3-O-caffeoylquinic acid and 3, 5-di-O-caffeoylquinic acid identified by contrast reference substances, respectively. Conclusion: The active substances in nonvolatile fraction of B. balsamifera are obtained through the study on the relationship between spectrum and efficiency, and the anti-inflammatory efficacy of the nonvolatile fraction is the result of combination of various components.It is clear that the caffeoylquinic acid derivates act as predominant anti-inflammatory active substance of nonvolatile fraction of B. balsamifera.

ABSTRACT

Objective@#To evaluate the efficiency of preoperative Halo-gravity traction (HGT) in the treatment of severe kyphoscoliosis secondary to neurofibromatosis type Ⅰ (NF1).@*Methods@#A retrospective review was conducted on patients with severe kyphoscoliosis secondary to NF1 at Department of Spinal Surgery, Drum Tower Hospital, Medical School of Nanjing University between July 2007 and May 2016. A total of 29 patients including 17 males and 12 females were finally enrolled and the age was (13.7±2.9) years. The Cobb angle of major coronal curve and global kyphosis were measured before and after HGT. The forced vital capacity (FVC)and forced expiratory volume in 1 second (FEV1) before and after traction were also recorded. The paired t test was used for comparison analysis.@*Results@#The average maximum traction weight of HGT was (12.2±2.8) kg and the traction duration was (10.2±6.6) weeks. The coronal Cobb angle before HGT was (87.5±36.5)°, which improved to (68.4±25.9)° after HGT with a correction rate of (21.9±12.1)% (t=9.14, P<0.001); the average global kyphosis before HGT was (79.1±27.1)°, which improved to (59.9±19.4)° after HGT and the correction rate was (20.2±14.1)% (t=8.55, P<0.001). One patient had transient brachial plexus palsy which resolved completely after reducing the traction weight. After HGT treatment, FVC increased from (0.83±0.16) L to (0.89±0.19) L (t=1.48, P=0.12) and FEV1 increased from (0.72±0.16) L to (0.78±0.20) L (t=0.49,P=0.63). FVC predicted and FEV1 predicted improved from (42.9±20.1)% and (40.6±19.6)% to (46.9±20.5)% (t=0.98,P=0.33) and (43.6±25.8)% (t=1.24,P=0.22), respectively.@*Conclusion@#Preoperative HGT in the treatment of severe kyphoscoliosis secondary to NF1 can improve spinal deformity and pulmonary function to some extent, which can further benefit the patients by improving their surgical tolerance.
