Objective: To explore clinical effect of modified Chinese-way technique under shoulder arthroscopy in treating massive rotator cuff tears.
Methods: From January 2019 to June 2022, 22 patients with massive rotator cuff tears who underwent arthroscopic rotator cuff repair with improved Chinese-way technique, including 10 males and 12 females, aged from 46 to 76 years old with an average of(64.14±7.45) years old;the courses of disease ranged from 5 to 14 months with an average of(8.32±2.42) months;19 patients were complete repaired, and 3 patients were partial repaired. Visual analogue scale (VAS) and University of California at Los Angeles (UCLA) scale were used to evaluate pain and function of shoulder joint preoperatively and 1 year postoperatively. Postoperative complications, the integrity of reconstructed tissue structure and the size of subacromial space were observed.
Results: All patients were followed up from 12 to 34 months with an average of (17.14±5.93) months. Re-tear were occurred in 4 patients during MRI follow-up, but clinical symptoms of patients were improved significantly and they were satisfied with the treatment, the others were no complications such as incision infection, peripheral nerve injury, loosening and falling off of internal fixation anchors. Preoperative and 1 year after operation VAS were (8.05±1.12) and (1.82±1.50), UCLA scores were (7.45±1.65) and (31.41±2.87) respectively, and the difference was statistically significant (P<0.05).
Conclusion: The modified Chinese-way technique under shoulder arthroscopy for the massive rotator cuff tear could relieve pain obviously and recovery postoperative function well, with satisfactory curative effect.
Objective: To explore causal relationship between atopic diseases (asthma and atopic dermatitis) and osteoarthritis (OA) by using mendelian randomization(MR).
Methods: Asthma and atopic dermatitis as instrumental variables were selected, searched them through IEU database, and selected the latest data with a large number of cases and single nucleotide polymorphism (SNP). Data were collected and processed using R language, inverse varianceweighted (IVW) method was adopted as main MR Evaluation method. Single linear regression was performed to estimate causality based on pooled knee and hip data from genome-wide association studies (GWAS). The forest map was drawn to visualize the results, and gene pleiotropy and sensitivity were analyzed by scatter plot and funnel plot. At the same time, asthma, atopic dermatitis, body mass index (BMI), osteoporosis and OA were selected for multivariate MR Analysis to exclude the effect of horizontal pleiotropy on the results in GWAS data.
Results: Analysis of MR-IVW results showed asthma was positively correlated with causal effect of OA [OR=1.41, 95%CI(1.07, 1.85), P=0.02], multivariate Mendelian randomization (MVMR) adjusted for BMI and osteoporosis and a direct causal effect on OA was observed [OR=1.57, 95%CI(1.03, 2.39), P=0.03)]. MR Results of two samples of atopic dermatitis and OA were [OR=1.01, 95%CI(0.97, 1.04), P=0.76], and MVMR results were [OR=1.02, 95%CI(0.99, 1.05), P=0.25], indicating no clear causal relationship between two samples.
Conclusion: Asthma could increase risk of OA, atopic dermatitis has no obvious relationship with OA, and the relationship between atopic diseases and OA still needs to be discussed.
Objective: To explore the clinical efficacy and safety of one-stage posterior lesion removal and internal spinal fixation in patients with lumbar Brucellosis spondylitis.
Methods: The clinical data of 24 patients admitted from October 2017 to October 2022 were retrospectively analyzed, 2 patients were lost to follow-up at 10 months after surgery, at the final 22 cases were included in the study, including 13 males and 9 females with an average age of (52.00±6.89) years old, were treated with one-stage posterior lesion removal and internal spinal fixation. The operation time, intraoperative bleeding, follow-up time, erythrocyte sedimentation rate(ESR) and C-reactive protein(CRP) before and after operation were recorded. The pain visual analogue scale(VAS), Oswestry disability index(ODI), the Japanese Orthopaedic Association(JOA) score for neurofunction, American Spinal Injury Association(ASIA) spinal cord injury grade and modified MacNab criteria were ussed to evaluate the efficacy.
Results: All patients were followed up from 12 to 30 months with an average of (17.41±4.45) months. The operation time was 70 to 155 min with an average of (116.59±24.32) min;the intraoperative bleeding volume was 120 to 520 ml with an average of (275.00±97.53) ml. CRP and ESR levels decreased more significantly at 1 week and at the final follow-up than preoperative levels(P<0.05). VAS, JOA score and ODI at 1 week and at the latest follow-up were more significantly improved than preoperative results(P<0.05). There was no significant difference between ASIA preoperative and 1 week after operation(P>0.05), and a significant difference between preoperative and last follow-up(P<0.05). In the final follow-up, 21 patients had excellent efficacy, 1 patient had fair, and there was no recurrence during the follow-up.
Conclusion: One-stage transpedicular lesion removal and internal spinal fixation, with few incisions and short operation time, helps the recovery of neurological function, and the prognosis meets the clinical requirements, which can effectively control Brucella spondylitis.
Objective: To investigate the effect of locking plate internal fixation for the treatment of proximal lateral femoral wall fracture.
Methods: From January 2021 to June 2022, 31 patients with intertrochanteric fractures and lateral wall fractures were treated. Among them, 15 patients were treated with proximal femoral nail antirotation (PFNA) fixation including 3 males and 12 females with an average age of (75.87±7.46) years old;the other 16 patients were treated with 3.5 mm pre-curved screw locking plate fixtion for lateral wall fracture including 4 males and 12 females with an average age of (76.15±9.47) years old. After surgery, the surgical index, tip-apical distance(TAD), postoperative standing weight-bearing time, and fracture reduction were compared between two groups. Postoperative hip function was evaluated according to Harris hip score.
Results: All patients were followed up for an average of (12±5) months ranging from 7 to 17 months. The immediate postoperative neck angle ranged from 111° to 132°(119.3±8.3)°. Fracture reduction results were excellent in 11 cases, fair in 2, worse in 1 in PFNA group;excellent in 12, fair in 3, worse in 1 in PFNA+locking plate group. One case of the PFNA group had a spiral blade cut out through the femoral head. There were significant differences in the time of operation, the amount of blood loss during the operation, the length of incision between two groups(P<0.05). There was no significant difference in TAD and postoperative standing weight-bearing time between two groups(P>0.05). There were significant differences in Harris scores at 6 months after surgery between two groups(P<0.05).
Conclusion: The application of PFNA-assisted locking plate in the treatment of femoral intertrochanteric fractures with lateral wall fractures is effective, and can restore the integrity of lateral wall, improve the stability of PFNA internal fixation, and reduce postoperative complications.
Objective: To analyze the relational factors influencing the formation of cauda equina redundant nerve roots (RNRs) of the lumbar spinal stenosis.
Methods: Clinical data of 116 patients with lumbar spinal stenosis treated from January 2016 to June 2019 were retrospectively analyzed. The patients were divided into redundant nerve roots(RNRs) group and non-RNRs group based on the presence or absence of RNRs on sagittal T2-weighted MRI. In the non-RNRs group, there were 74 patients, including 38 males and 36 females with an average age of (62.00±10.41) years old, the body mass index (BMI) was (23.09±2.22) kg·m-2;the maximum stenosis segment was L2-L3 in 12 cases, L3-L4 in 38, L4-L5 in 20, and L5S1 in 4, respectively. In the RNRs group, there were 42 patients, including 18 males and 24 females with an average age of (63.36±8.73) years old, the BMI was (22.63±2.60) kg·m-2;the maximum stenosis segment was L2-L3 in 3 cases, L3-L4 in 9, L4-L5 in 27 and L5S1 in 3, respectively. MRI was performed in the supine position to observe the conshape and morphology of the redundant nerve in the sagittal position. The preoperative low back and leg pain visual analogue scale(VAS), and preoperative Oswestry disability index(ODI) were analyzed, and the rate of spondylolisthesis and ligamentum flavum hypertrophy were compared. Simultaneously, the inter-vertebral height, intervertebral foramen height, inter-vertebral height+vertebral height, median sagittal diameter at the inter-vertebral space level(DIW-MSD), median sagittal diameter at the pedicel level(DV-MSD), range of motion(ROM) of the stenotic segment were measured and analyzed.
Results: Among the 116 patients with lumbar spinal stenosis, 42 patients developed RNRs, with an incidence of 36.2%. There were no significant differences in gender, age, BMI, preoperative VAS for lumbar and leg pain and ODI between two groups(P>0.05). There were statistically significant differences regard to the duration of symptoms and the rate of spondylolisthesis and ligamentum flavum hypertrophy (P<0.05);the inter-vertebral height, intervertebral foramen height, inter-vertebral height+vertebral height, DIW-MSD, ROM of the stenotic segment were also significantly different between two groups(P<0.05). However, there was no significant difference in DV-MSD between two groups(P>0.05).
Conclusion: The inter-vertebral height, inter-vertebral foramen height, inter-vertebral height+vertebral height, DIW-MSD and ROM of the stenotic segment were the crucial factors related to RNRs in lumbar spinal stenosis.
Objective: To observe the clinical efficacy of meridian massage in the treatment of cervical spondylotic radiculopathy.
Methods: Sixty-four patients with cervical radiculopathy treated from March 2020 to June 2023 were divided into the observation group and the treatment group, with 32 cases in each group. The observation group received conventional treatment, including 14 males and 18 females with an average age of (41.34±7.23) years old ranging from 32 to 55 years old;the disease duration ranged from 9 to 17 months with an average of (14.23±3.56) months;C5 and C6 nerve root compression occurred in 12 cases, C7 nerve root compression occurred in 17 cases, C8 nerve root compression occurred in 3 cases. The treatment group received massage therapy on the basis of conventional treatment, including 17 males and 15 females with an average age of (40.86±6.97) years old ranging from 30 to 54 years old;the disease duration ranged from 8 to 18 months with an average of (15.43±3.48) months;C5 and C6 nerve root compression occurred in 14 cases, C7 nerve root compression occurred in 16 cases, C8 nerve root compression occurred in 2 cases. The clinical efficacy was evaluated by visual analogue scale(VAS), neck disability index(NDI) and clinical assessment scale for cervical spondylosis(CASCS) before and after 2-week treatment, and the range of motion of cervical spine was compared before and after treatment.
Results: After 2-week treatment, the VAS and NDI scores of the treatment group and the observation group decreased, while the CASCS scores increased(P<0.001). After 2-week treatment, the VAS and NDI scores were lower and the CASCS scores were higher in the treatment group than those of the observation group(P<0.001). Comparing with those before treatment, the range of motion of flexion, extension, left flexion, right flexion, left rotation and right rotation after 2-week treatment increased in two groups(P<0.05). Comparing with the observation group, the range of motion of flexion, extension, left flexion, right flexion, left rotation and right rotation increased more significantly in the treatment group(P<0.05).
Conclusion: Meridian massage is effective in the treatment of cervical Spondylotic radiculopathy, which can effectively relieve neck pain, improve clinical symptoms and improve patient satisfaction.
Objective: To study the effect of intervertebral grafting area on the effect of single segment lumbar posterior decompression and intervertebral bone grafting fusion.
Methods: The clinical data of 52 patients who underwent single-segment lumbar posterior decompression pedicle internal fixation and bone grafting fusion from January 2020 to December 2022 were retrospective reviewed. The area of the intervertebral bone graft was measured one week postoperatively using Computed Tomography (CT), and based on the ratio of the bone graft area to the average area of the endplates, the patients were divided into three groups:17 cases in group A(the intervertebral bone graft area did not exceed the area of one pedicle) included 9 males and 8 females with an average age of (56.0±11.5) years old;15 cases in group B(the intervertebral bone graft area exceeded one pedicle but did not reach the opposite pedicle) included 10 males and 5 females with an average of (52.0±14.0) years old; 20 cases in group C (the intervertebral bone graft area exceeded the opposite pedicle) included 12 males and 8 females with an average of (49.5±12.8) years old. X-rays and CT scans were performed at 3, 6, 12 months, and the final follow-up postoperatively, the interbody fusion Brantigan scores, pain visual analogue scale (VAS), and Oswestry Disability Index (ODI) at each follow-up were recorded.
Results: The gender, age, and surgical segments showed no significant differences among three groups(P>0.05). There was also no significant difference in the preoperative VAS and ODI among three groups (P>0.05). All patients of three groups were followed up from 12 to 36 months. Compared with preoperative, VAS and ODI scores of three groups showed significant improvement at 1 week postoperatively and the final follow-up (P<0.05). Compared with preoperative measurements, the height of the intervertebral space was restored at 1 week postoperatively in three groups;at the final follow-up, the loss of height in the intervertebral space was less in groups B and C, and the height of the intervertebral space in group B and C was significantly higher than in group A(P<0.05). The modified Brantigan scores at 3 and 6 months postoperatively were significantly higher in group C than in groups A and B (P<0.05);at 12 months postoperatively, the scores in groups B and C were significantly higher than in group A(P<0.05);however, at the final follow-up, there was no significant difference in the modified Brantigan scores among three groups(P>0.05). The bone graft fusion rate in group C was significantly higher than in groups A and B at 3 months postoperatively(P<0.05);at 6 and 12 months postoperatively, the fusion rates in groups B and C were significantly higher than in group A(P<0.05);at the final follow-up, the fusion rate in group A was still lower than in groups B and C, but
