OBJECTIVE To explore the pharmaceutical care of reactivating anthracycline chemotherapy in patients with advanced breast cancer complicated with thyroid cancer. METHODS Clinical pharmacists participated in the whole treatment process of a patient with advanced breast cancer complicated with thyroid cancer and provided personalized medication recommendations. Considering that the patient currently has multiple primary anti-tumor drug resistance， clinical pharmacists recommend reactivating the EC rescue protocol （intravenous infusion of epirubicin hydrochloride 140 mg+cyclophosphamide 1 g， d1， 21 days for a cycle）. The cumulative lifetime dose of epirubicin and the optimal course of chemotherapy was estimated according to the body weight change of the patient. Given the issue that abnormal fluctuation of thyroid stimulating hormone （TSH） level during chemotherapy may increase the risk of cardiac toxicity， clinical pharmacists suggest adopting a dose adjustment strategy of “fast first and slow later” for Levothyroxine sodium tablet according to the target range of TSH and test results. RESULTS The doctors adopted the pharmacists’ suggestion； the clinical pharmacists assisted the doctors in reactivating the anthracycline-based 7-cycle combination regimen， during which the patient had no significant cardiac adverse events and was repeatedly evaluated as stable. TSH decreased steadily after Levothyroxine sodium tablets were added， and no adverse reaction related to TSH inhibition was observed. CONCLUSIONS Patients with primary drug-resistant breast cancer complicated with thyroid cancer may be reactived anthracyclines if necessary， but baseline cardiac function and thyroid hormone levels should be tested before initiation， and cardiac toxicity risk assessment should be performed in combination with the patient’s history. Clinical pharmacists should actively exert their professional advantages to carry out whole-process pharmaceutical care for such patients， so as to ensure the safety of drug use for patients.

The cervicothoracic scoliosis Cobb angle, compensatory scoliosis Cobb angle, local kyphosis Cobb angle, torticollis angle, T 1 tilt angle and clavicular angle were measured before operation, model design, 1 week after operation and at the last follow-up to evaluate the effect of surgical design, intraoperative orthosis and the correction loss at follow-up. The Society for Scoliosis Research-22 (SRS-22) questionnaire was used to evaluate the functional and treatment effect. At the last follow-up, the osteotomy fusion was evaluated by Eck criterion. Results:All patients successfully completed the operation, the operation time was 228.5±41.8 min, the intraoperative blood loss was 355.6±46.7 ml, and the number of fusion segments was 5.5±0.8. Follow-up duration was 35.5±13.2 months. A total of 140 pedicle screws were inserted, with an accuracy of 97.1% (136/140). The Cobb angle of cervicothoracic scoliosis was 53.9°±17.9° preoperatively, 11.3°±4.4° in the model design, 10.8°±2.6° one week postoperatively, and 14.5°±3.5° at the last follow-up, with statistical significance ( P<0.001). The preoperative and postoperative one week difference was statistically significant ( P<0.001) with a correction rate of 78.6%±6.7%. The Cobb angle of compensatory scoliosis was 33.1°±12.1° before surgery, 11.9°±2.4° for model design, 10.5°±3.4° for one week after surgery, and 14.1°±2.5° for the last follow-up, with statistically significant differences ( P<0.001). The postoperative correction rate was 65.2%±16.2%. The Cobb angle of local kyphosis was 27.8°±9.8° preoperatively, 10.1°±2.1° in the model design, 9.8°±1.9° one week postoperatively, and 12.7°±1.6° at the last follow-up, with statistical significance ( P<0.001). The preoperative and postoperative one week difference was statistically significant ( P<0.001) with a correction rate of 59.2%±18.9%. The preoperative and postoperative one week difference was statistically significant ( P<0.001) with a correction rate of 78.6%±6.7%. The neck tilt angle was 20.6°±6.7° preoperatively, 6.2°±1.9° in the model design, 5.9°±2.1° one week postoperatively, and 7.1°±1.4° at the last follow-up, with statistical significance ( P<0.001). The preoperative and postoperative one week difference was statistically significant ( P<0.001) with a correction rate of 70.0%±11.1%. The T 1 inclination angle was 20.2°±5.8° preoperatively, 11.5°±3.1° in the model design, 10.2°±2.3° one week postoperatively, and 9.5°±3.0° at the last follow-up, with statistical significance ( P<0.001). The preoperative and postoperative one week difference was statistically significant ( P<0.001) with a correction rate of 53.2%±10.4%. There was no significant difference between preoperative design and actual measurement one week after surgery ( P>0.05). At the last follow-up, the scores of self-image (4.6±0.7), mental health (4.7±0.6) and treatment satisfaction (4.6±0.6)in SRS-22 scale were significantly improved compared with those before operation ( P<0.05). The symptoms of hemivertebra ipilateral C 8 nerve root injury occurred in 1 patient, who was treated conservatively with dehydration, hormones and nutraceutical drugs, and recovered to normal at 3 months follow-up. At the last follow-up, the appearance of the head, neck and shoulders of the patients was improved compared with that before surgery, the bone grafts have achieved osseous fusion in all patients. All fusion were grade I by Eck criterion. No complications such as serious neurological or vascular injury occurred during perioperative period. No pseudoarthrosis formation, internal fixation loosening or fracture occurred during follow-up. Conclusion:The application of 3D printing combined with O-arm navigation assistance technology in posterior hemivertebra resection and correctional surgery for cervicothoracic hemivertebra deformities can display the deformities in advance, stereoscopic and real-time, accurately place pedicle screws and complete hemivertebra resection, improve surgical safety and deformity correction rate.

Derived from embryonic stem cells, induced pluripotent stem cells, or adult stem cells, liver organoids not only mimic the tissue structure, gene expression patterns, and genetic characteristics of in vivo liver but also demonstrate significant potential in simulating liver diseases, drug screening, precision medicine, and regenerative medicine. This technology is particularly valuable in modeling various conditions such as malignant liver tumors, liver fibrosis, cirrhosis, viral hepatitis, and a range of genetic and metabolic liver diseases. However, challenges remain in enhancing the derivation and proliferation efficiency of organoids, constructing immune microenvironments, developing functional vascular networks, and achieving standardization and automation in the organoid preparation process. Looking forward, with continued technological advancements and innovations, these issues are expected to be resolved, paving the way for liver organoids to play a more substantial role in clinical and research applications, ultimately contributing significantly to public health. This review comprehensively explores the development and extensive applications of liver organoid technology in the field of biomedical science. The aim is to inform subsequent research.

Objective:To investigate the clinical efficacy of satellite rod revision surgery via a combined anterior and posterior approach for rod fracture after posterior vertebral column resection (PVCR) in patients with severe thoracolumbar kyphosis.Methods:A retrospective case series study was conducted on the clinical data of 11 patients with rod fracture after PVCR for severe thoracolumbar kyphosis, who were treated in Henan Provincial People′s Hospital from January 2013 to January 2021. There were 6 males and 5 females, with the age range of 21-62 years [(35.4±13.0)years]. Among them, 4 patients had traumatic kyphosis, 4 presented congenital kyphosis and 3 showed tuberculous kyphosis. All the patients had obvious low back pain. According to the American Spinal Injury Association (ASIA) score, 2 patients were found with grade C, 2 with grade D and 7 with grade E. All the patients underwent revision surgery for internal fixation using satellite rod via a combined anterior and posterior approach. The operation time, intraoperative blood loss and postoperative hospital stay were recorded. The imaging parameters such as kyphosis Cobb angle, scoliosis Cobb angle, distance between C 7 plumb line and central sacral vertical line (C 7-CSVL), and distance between C 7 plumb line and sagittal vertical axis (SVA) were measured preoperatively, at 1 week postoperatively and at latest follow-up. At the same time, the visual analogue scale (VAS), Oswestry dysfunction index (ODI), and simplified Chinese version of the scoliosis research society-22 (SRS-22) questionnaire were used to evaluate the clinical efficacy. At the latest follow-up, the osteotomy fusion was evaluated by Suk criterion and ASIA score was used to evaluate the recovery of neurological function. The complications were also recorded for the patients. Results:All the patients were followed up for 24-84 months [(47.5±16.2)months]. The operation time was 100-220 minutes [(149.4±37.6)minutes], with the intraoperative blood loss of 150-350 ml [(246.3±64.6)ml] and the postoperative hospital stay of 5-8 days [(6.1±1.1)days]. The kyphosis Cobb angles [(18.5±3.2)° and (19.3±2.9)°] and the scoliosis Cobb angles [(11.8±2.2)°, (11.1±2.2)°] at 1 week post-operation and at the latest follow-up were all improved significantly compared with the preoperative ones [(60.4±6.3)°, (21.7±5.5)°] (all P<0.01), with the average correction rates being 69.4% and 45.6%, respectively, with no significant differences between 1 week post-operation and latest follow-up (all P>0.05). The C 7-CSVL was reduced from preoperative (21.2±4.3)mm to (15.7±2.4)mm at 1 week post-operation, and to (15.9±2.2)mm at the latest follow-up (all P<0.01). The SVA was improved from preoperative (51.0±6.8)mm to (16.6±3.6)mm at 1 week post-operation, and to (15.3±3.9)mm at the latest follow-up (all P<0.01). There were no significant differences in C 7-CSVL or SVA at 1 week post-operation or at the latest follow-up (all P>0.05). The VAS [(2.5±0.9)points, (1.9±0.9)points], ODI (20.1±5.4, 18.4±5.2) and SRS-22 [(83.4±5.8)points, (85.0±4.1)points] at 1 week post-operation and at the latest follow-up were significantly improved compared with the preoperative ones [(6.0±1.4)points, 57.2±8.7, (62.0±9.1)points] (all P<0.01), but no significant differences were found between 1 week post-operation and latest follow-up (all P>0.05). At the latest follow-up, the bone grafts achieved osseous fusion in all the patients, and the ASIA grade was improved from grade C to grade D in 2 patients and from grade D to grade E in 2 patients. No complications such as serious neurological or vascular injury occurred during perioperative period. No pseudoarthrosis formation, internal fixation loosening or fracture occurred during follow-up. Conclusion:Satellite rod revision surgery via a combined anterior and posterior approach for rod fracture after PVCR in patients with severe thoracolumbar kyphosis has the advantages of less trauma and faster convalescence, excellent results of deformity correction, significant pain relief, functional improvement, and fewer complications.

Objective:To investigate the clinical efficacy and precautions of O-arm combined with navigation-assisted steotomy and hemivertebra resection for congenital cervicothoracic hemivertebra.Methods:From February 2016 to October 2020, the clinical data of 12 patients with cervicothoracic hemivertebra admitted in Henan Provincial People's Hospital were retrospectively analyzed, including 5 males and 7 females, aged 9.4±2.6 years (range, 4-15 years). Intraoperative neural monitoring system was used to ensure the safety of surgical correction process and O-arm navigation system assisted the implantation of pedicle screws,hemivertebra resection, and scoliosis deformity correction. Postoperative CT was used to evaluate the accuracy of screw placement, and routine preoperative and postoperative X-ray films of the full-length spine in standing position were taken to measure the coronal and sagittal Cobb angles. The correction rate of scoliosis and kyphosis, internal fixation, shoulder height difference and bone graft fusion were calculated at the final follow-up.Results:A total of 108 pedicle screws were inserted in 12 patients, and the screw placement accuracy rate was 96.3% (104/108). The follow-up time was 37.9±10.2 months (range, 24-61 months). The number of fused segments was 5.4±1.1 (range, 4-7). One week after surgery, the correction rate of Cobb angle was 78.5%±3.2% for scoliosis and 70.1%±5.4% for kyphosis. There were statistically significant differences in side and kyphosis Angle and Scoliosis Research Society (SRS)-22 score between preoperative and 1 week after surgery ( P<0.05). There was no significant difference between the operation and the last follow-up ( P>0.05). At the last follow-up, all the 12 patients achieved gradeⅠ fusion. SI was 2.4±0.8 cm before operation, 1.0±0.6 cm at 1 week after operation, and 0.7±0.5 cm at last follow-up, and the difference was statistically significant ( F=38.30, P<0.001). No pseudojoint formation, significant loss of correction Angle, or rupture of internal fixation relaxant occurred during the operation or during follow-up. Conclusion:O-arm combined with navigation-assisted steotomy and hemivertebra resection for the treatment of congenital cervicothoracic hemivertebra has the advantages of good orthopedic effect, reduced radiation exposure and fewer complications, and accurate pedicle screw implantation and hemivertebra resection.

Objective:To investigate the imaging features of solitary bone plasmacytoma (SBP) and to improve the diagnosis of SBP.Methods:The imaging and clinical data of 8 cases clinically diagnosed as SBP at different sites from September 2012 to September 2020 in Yuanping First People's Hospital of Shanxi Province were retrospectively analyzed. Imaging examinations included CT, magnetic resonance imaging (MRI) plain scan and enhanced MRI scan.Results:The lesion sites of 8 patients included 3 cases of thoracic vertebrae, 2 cases of lumbar vertebrae, 2 cases of skull, and 1 case of rib. Among them, 1 case was misdiagnosed as thoracic metastatic tumor, 1 case as thoracic tuberculosis, 1 case as lumbar lymphoma and 1 case as cranial meningioma. Osteolytic destruction of bone was found in all cases accompanied by expansible changes of bone and soft tissue masses. There were 5 cases of vertebral bodies compressed and flattened; CT showed equal/low density, T1WI showed equal/low signal, T2WI showed low/slightly high signal, and 2 cases showed typical "mini brain sign". There were 2 cases of skull with slight hyperintensity on CT, isointensity on T1WI, and equal/mixed hyperintensity on T2WI. The rib cases showed isodensity on CT, T1WI showed isointensity, T2WI showed slightly high intensity. The lesions of 4 SBP patients showed obvious uniform enhancement on MRI enhanced scan.Conclusions:SBP at different sites can show osteolytic destruction with uniform enhancement of lesions and soft tissue masses. "Mini brain sign" is the SBP-specific imaging sign of the spine.

Objective: To investigate the clinical efficacy of percutaneous fixation assisted by O-arm-based navigation for thoracolumbar fractures without neurologic deficits. Methods: A retrospective case control study was conducted to analyze the clinical data of 35 thoracolumbar fracture patients without neurologic deficits admitted to Henan Provincial People's Hospital from January 2018 to December 2018. There were 26 males and 9 females, aged 17-51 years, with an average age of 30.4 years. The injured segments were distributed at T₁₁ in 10 patients, T₁₂ in 15, L₁ in 11, and L₂ in 4 patients. A total of 19 patients (22 vertebrae, 98 pedicle screws) were treated with O-arm guided navigation assisted percutaneous internal fixation (Group A), and 16 patients (18 vertebrae, 82 pedicle screws) were treated with C-arm guided percutaneous internal fixation (Group B). The operation time, accuracy rate of nail placement, complications, Cobb angle of fracture vertebral body, visual analogue score (VAS) and Japanese Orthopaedic Association (JOA) score were recorded and compared before operation, 7 days after operation and at the last follow-up. Results: The patients were followed up for 2-12 months [(7.2±2.9)months] in Group A and 3-13 months [(7.1±3.3)months] in Group B. The operation time was (70.5±11.2)minutes in Group A and (81.3±10.9)minutes in Group B (P<0.01). A total of 93 screws were completely placed in the pedicle in Group A (accuracy rate of 95%), and 74 screws in Group B (accuracy rate of 90%) (P<0.01). There were no complications such as infection, pulmonary embolism, spinal cord, nerve injury or lower extremity deep vein thrombosis in either group. The Cobb angle of the fractured vertebral body at day 7 after operation in Group A and Group B was (9.4±2.1)° and (10.4±2.5)° respectively, while the Cobb angle of the fractured vertebral body at the final follow-up in Group A and Group B was (9.7±2.3)° and (11.4±2.9)° respectively. The postoperative Cobb angle was significantly increased compared with the preoperative Cobb angle (P<0.05), but there was no significant difference between the two groups (P>0.05). The VAS at day 7 after operation was (2.3±1.1)points and (2.8±1.0)points in Group A and Group B, respectively, while the VAS at the final follow-up was (0.7±0.7)points and (0.8±0.7)points in Group A and Group B respectively. The postoperative VAS was significantly decreased compared with the preoperative VAS (P<0.05), but there was no significant difference between the two groups (P>0.05). The JOA at day 7 after operation was (21.1±2.2)points and (21.8±2.5)points in Group A and Group B respectively, while the JOA at the final follow-up was (24.9±2.2)points and (23.8±1.9)points in Group A and Group B respectively. The postoperative JOA was significantly increased compared with the preoperative JOA (P<0.05), but there was no significant difference between the two groups (P>0.05). Conclusion For thoracolumbar fractures without neurologic deficits, percutaneous fixation assisted by O-arm-based navigation can shorten the operation time and deliver a higher accuracy rate in the placement of pedicle screws, in addition to the similar effects with percutaneous fixation assisted by C-arm in pain relief, function improvement and correction of fracture vertebral kyphosis.

Objective To investigate the effect of LncRNA HULC on radiosensitivity of osteosarcoma cells. Methods Osteosarcoma cells OS732 was infected by shRNA HULC lentivirus, and the interference effect was determined by qRT-PCR. Osteosarcoma cells infected with shRNA HULC lentivirus were irradiated with 8 Gy X-rays. MTT, PI monochrome staining and Annexin V-FITC/PI double staining were used to detect cell proliferation, cell cycle and apoptosis, respectively. Western blot was used to detect the protein levels of p21, Cyclin D1, C-Caspase-3 and Cyt-C in cytoplasm and mitochondria. Plate cloning assay was used to evaluate cell radiosensitivity. Results The expression of HULC in osteosarcoma cells was significantly down-regulated by shRNA HULC lentivirus infection. Down-regulation of HULC or irradiation inhibited osteosarcoma cell proliferation [(100. 00±9. 65)％ vs. (71. 36±5. 27)％, (63. 48± 5. 93)％, t=4. 512, 5. 585, P<0. 05 ] , blocked cell cycle [ ( 50. 15 ± 5. 14 )％ vs. ( 62. 35 ± 4. 22 )％, (66. 05±5. 23)％,t=3. 177,3. 756,P<0. 05], induced cell apoptosis [(2. 98±0. 23)％ vs. (22. 61± 3. 26)％, (26. 14±2. 81)％,t=8. 898,10. 498,P<0. 05], promoted the expressions of p21 and Cyclin D1 in cells, down-regulated the level of C-Caspase-3 protein, increased the level of Cyt-C protein in cytoplasm, and down-regulated the level of Cyt-C protein in mitochondria. Downregulation of HULC combined with irradiation yield much more effects on cell proliferation inhibition [ ( 71. 36 ± 5. 27 )％, (63.48±5.93)％ vs. (49.32±5.76)％, t=4.890, 2.967, P<0.05], cell cycle arrest [(62.35± 4. 22)％, (66. 05±5. 23)％ vs. (77. 17±7. 54)％, t=2. 983, 2. 106, P<0. 05], apoptosis induction [(22. 61±3. 26)％, (26. 14±2. 81)％ vs. (36. 21±3. 26) ％,t=6. 164, 4. 564, P<0. 05] and the expressions of p21, Cyclin D1, C-Caspase-3 and Cyt-C in osteosarcoma cells. The radiosensitization ratio of down-regulation of HULC was 1. 432. Conclusions Down-regulation of HULC enhances radiosensitivity of osteosarcoma cells, which may be related to cell cycle arrest and apoptosis induction.

Objective To investigate the clinical efficacy of percutaneous vertebroplasty (PVP) with bone filling container (BFC) and percutaneous kyphoplasty (PKP) by unilateral puncture approach in the treatment of osteoporotic vertebral compression fractures.Methods A retrospective case control study was conducted on 65 patients (65 vertebral bodies) with osteoporotic vertebral compression fractures (OVCF) who received PVP from March 2015 to March 2017 in Henan Provincial People's Hospital.There were 21 males and 44 females,aged 60-91 years,with an average of 76.2 years.The patients were divided into PVP with BFC group (BFC group) and PKP group treated by unilateral puncture approach.There were 10 males and 23 females in BFC group,with an average age of 75.8 years (range,60-91 years).The injured segments were distributed at T10 in seven patients,T11 in nine,T12 in eight,L1 in five,and L2 in four patients.There were 11 males and 21 females in PKP group,with an average age of 76.7 years (range,60-88 years).The injured segments were distributed at T10 in five patients,T11 in seven,T12 in ten,L1 in eight,and L2 in two patients.The operation time,cement leakage,as well as pain visual analogue score (VAS),modified Oswestry dysfunction index (ODI) and the Cobb angle of the fractured vertebral body at 3 days after operation and 12 months after operation were recorded and compared.Results All operations were completed successfully,without serious complications.The patients were followed up for 16-29 months [(21.2 ± 4.5) months] in BFC group and 15-32 months [(23.8 ± 6.2) months] in PKP group.The operation time was (27.8 ± 3.6) minutes in BFC group and (31.0 ± 5.2) minutes in PKP group (P ＜ 0.05).Postoperative X-ray and CT showed that bone cements leakage occurred in three patients of BFC group (9％) and in ten patients of PKP group (31％) (P ＜0.05).The VAS at 3 days after operation in BFC group and PKP group was (2.3 ± 1.0) points and (2.1 ±0.8)points respectively.The VAS at 12 months after operation in BFC group and PKP group was (0.7 ± 0.7) points and (O.8 ± 0.7) points respectively.The postoperative VAS was significantly decreased compared with the preoperative VAS (P ＜0.05),but there was no significant difference between the two groups (P ＞ 0.05).The modified ODI at 3 days after operation in BFC group and PKP group were (31.5 ± 4.7) ％ and (30.4 ± 5.7) ％,respectively.The modified ODI at 12 months after operation in BFC group and PKP group was (16.7 ±4.9)％ and (15.1 ±5.6)％,respectively.The postoperative ODI were significantly decreased compared with the preoperative ODI(P ＜0.05),but there was no significant difference between the two groups (P ＞ 0.05).The Cobb angle of the fractured vertebral body at 3 days after operation in BFC group and PKP group was (9.2 ± 3.0) ° and (10.0 ±2.9)°,respectively.The Cobb angle of the fractured vertebral body at 12 months after operation was (9.6 ± 2.8)° and (10.3 ± 3.0)°respectively.The postoperative Cobb angle was significantly decreased compared with the preoperative Cobb angle (P ＜ 0.05),but there was no significant difference between the two groups (P ＞ 0.05).Conclusions For OVCF,PVP with BFC by unilateral puncture approach can shorten the operation time and reduce the leakage rate of bone cement.It has similar effects with PKP in pain relief,function improvement of daily life and the correction of fracture vertebral kyphosis.

Objective To investigate the different operation methods for kyphosis deformity of ankylosing spondylitis(AS)complicated with cervical vertebral fracture and their effects.Methods A retrospective case series study was conducted to analyze the clinical data of 19 patients with AS kyphosis complicated with cervical vertebral fracture admitted to Henan People's Hospital from April 2007 lo October 2017.There were 18 males and one female,aged 28-73 years,with an average age of 38.6 years.Among the patients,17 were complicated with spinal cord dysfunction.According to the American spinal injury association(ASIA)classification,there were four patients with grade A,five with grade B,five with grade C and three with grade D.According to the degree of nerve injury and the displacement of fracture,reduction and fixation or orthopedic fixation were selected;14 patients with severe nerve injury(ASIA grades A-C)were treated with reduction and fixation,of which six were treated by simple anterior approach,two by simple posterior approach,five by combined anterior-posterior approach,and one by combined anterior-posterior approach 2 months after Halo fixation.Five patients with ASIA grade D or E were treated with orthopedic fixation.Firstly,kyphosis was corrected with manual technique and the Halo external fixator was installed,and then surgical fixation fusion was performed via simple posterior approach(one patient)or combined anterior-posterior approach(four patients).Visual analogue scale(VAS)was used to evaluate the relief of neck pain.The improvement of nerve function,the effect of orthopedic fixation,the fracture healing time and the postoperative complications were recorded.Results One patient died 11 days after operation due to pulmonary infection and respiratory failure.The remaining patients were followed up for 1-10 years,with an average of 27.3 months.The neck pain in all patients was relieved significantly,and the VAS score[(2.9±0.9)points]decreased significantly 3 days after operation compared with that before operation[(8.2±1.0)points](P＜ 0.05).The nerve function of 12 patients improved significantly(P＜ 0.05).The chin-brow vertical angle of the patients after orthopedic fixation was 60-180(mean,11.8°),suggesting that the level vision function was restored.Fracture healing time ranged from 3 to 8 months,with an average of 3.9 months.There were 4 patients with cerebrospinal fluid leakage and three patients with pulmonary infection.No complications such as wound infection and aggravation of nerve injury occurred.Conclusions For AS kyphosis combined with cervical spine fracture,if without severe nerve injury,manual correction of kyphosis and installation of Halo frame followed by fixation and fusion can effectively correct spinal deformity and improve the quality of life.Patients with severe spinal cord injury should avoid stage I correction and receive reduction of fracture and long segment fusion fixation as far as possible to facilitate the recovery of nerve function.
