Objective: To explore the integrated traditional Chinese and Western medicine treatment plan for ankylosing spondylitis complicated with lower cervical spine fracture and dislocation, adopt the treatment plan of preoperative continuous traction, intraoperative prizing reduction combined with anterior long-segment plate-screw and posterior short-segment pedicle screw-rod system internal fixation, and evaluate its surgical efficacy and clinical application value.Methods: From June 2018 to September 2022, 7 male patients with ankylosing spondylitis complicated with lower cervical spine fractures were admitted, aged 43 to 65 years old. Among them, there was 1 case of C3,4 fracture, 1 case of C4,5 fracture, 1 case of C6,7 fracture, and 4 cases of C5,6 fracture, all of which were fracture and dislocation. All patients received preoperative continuous skull traction, and intraoperative prizing reduction combined with anterior long-segment plate-screw and posterior short-segment pedicle screw-rod system internal fixation. The Neck Disability Index (NDI), Japanese Orthopedic Association (JOA) score, and Frankel scale were used to evaluate the neurological function and quality of life before and after surgery. The visual analogue scale (VAS) was used to evaluate neck and limb pain. The operation time, blood loss, hospital stay, and surgery-related complications were recorded.Results: All 7 patients were followed up for 6 to 24 months after surgery. The operation time of the 7 patients ranged from 300 to 480 minutes, the blood loss ranged from 300 to 1000 ml, and the hospital stay ranged from 8 to 25 days. The preoperative NDI of the 7 patients ranged from 25% to 42%, which decreased to 12% to 30% at 1 week after surgery and 5% to 25% at the last follow-up. The preoperative JOA score ranged from 8 to 13 points, which increased to 12 to 15 points at 1 week after surgery and 13 to 16 points at the last follow-up. The preoperative VAS ranged from 6 to 8 points, which decreased to 2 to 4 points at 1 week after surgery and 0 to 3 points at the last follow-up. Regarding the Frankel grade of neurological function, 2 patients were grade C before surgery and recovered to grade D at the last follow-up after surgery, and the remaining patients recovered to grade E at the last follow-up after surgery. There were 3 cases of pressure ulcers, including 1 case of intraoperative pressure ulcer, 1 case of cervical cerebrospinal fluid leakage, 1 case of screw loosening, and 1 case of aggravated fracture dislocation due to preoperative traction.Conclusion: Preoperative cervical traction combined with intraoperative prizing reduction and anterior long-segment plate combined with posterior short-segment pedicle screw internal fixation provides a safe and effective surgical option for ankylosing spondylitis complicated with lower cervical spine f

Objective: To explore the optimal vertical traction weight, clinical efficacy, and safety of bidirectional cervical traction in the treatment of cervical kyphosis.

Methods: A total of 130 patients with neck pain and cervical kyphosis confirmed by cervical DR who visited the hospital from April 2023 to April 2024 were enrolled. They were divided into 4 groups according to the vertical traction weight accounting for 5%, 10%, 15%, and 20% of their body weight, respectively. The 5% body weight traction group included 33 cases (13 males and 20 females) with an average age of (34.00±10.58) years old;the 10% body weight traction group included 35 cases (17 males and 18 females) with an average age of (32.23±8.39) years old;the 15% body weight traction group included 32 cases (14 males and 18 females) with an average age of (33.88±10.09) years old;the 20% body weight traction group included 30 cases (11 males and 19 females) with an average age of (36.20±9.13) years old. Each group received treatment for 2 weeks. The visual analogue scale (VAS) score, neck disability index (NDI), and C₂-C₇ Cobb angle on cervical lateral X-ray films before and after treatment were recorded to evaluate the clinical efficacy of the 4 groups.

Results: When the traction weight was 10% and 15% of body weight, the pain VAS and NDI were significantly improved, and the C₂-C₇ Cobb angle increased, with statistically significant differences (P<0.05), and no adverse reactions occurred. However, in the 5% body weight group, the above indicators showed no significant changes, with no statistically significant differences (P>0.05). In the 20% body weight group, some patients could not tolerate the treatment, and adverse reactions such as dizziness, nausea, and aggravated neck pain occurred.

Conclusion: The optimal vertical traction weight of bidirectional cervical traction for cervical kyphosis is 10%-15% of body weight, which can effectively improve neck pain and cervical function, increase the C₂-C₇ Cobb angle of the cervical spine, with high safety, and is worthy of promotion and application.

Objective: To establish a two-segment vertebrectomy model using the finite element method, and to measure and compare the biomechanical properties of the lower cervical anterior transpedicular root screw (ATPRS) plate system, lower cervical anterior pedicle screw (ATPS) plate system, and lower cervical anterior cervical locked-plate (ACLP) system on this model.Methods: CT data of the cervical spine (C0-T1) from a 34-year-old healthy adult male volunteer were collected. A nonlinear complete model of the lower cervical spine (C3-C7) was established using Mimics 10.01 software, based on which the ATPRS fixation model, ATPS fixation model, and ACLP fixation model were constructed respectively. An axial pressure of 75 N and a pure couple moment of 1.5 N·m were applied to C3 to make the model perform flexion-extension, left-right lateral bending, and left-right rotation movements. The range of motion (ROM) and stress distribution of each model under different working conditions were compared.Results: The ROM of the C4-C7 segments in the ACLP group, ATPS group, and ATPRS group was reduced to 0.65° (-95.2%), 0.58° (-95.7%), and 0.62° (-95.4%) respectively compared with the intact model during flexion-extension movement;during lateral bending movement, it was reduced to 0.58° (-95.2%), 0.51°(-95.8%), and 0.60° (-95.1%) respectively;during rotation movement, it was reduced to 1.17° (-89.6%), 1.26° (-88.8%), and 1.27°(-88.7%) respectively. In terms of the stress on the titanium mesh graft, the ATPS group and ATPRS group had the maximum load during extension and the minimum load during flexion. Compared with the ACLP group, the stress on the titanium mesh graft in ATPS and ATPRS decreased by (-33.7%) and (-15.8%) in flexion, (-29.4%) and (-13.2%) in extension, (-26.2%) and (-23.4%) in lateral bending, and (-18.8%) and (-5.4%) in rotation, respectively. In terms of bone-screw interface stress, the peak bone stress near the C7 screw in the ACLP group, ATPS group, and ATPRS group increased by 49.2%, 45.0%, and 47.6% respectively compared with the peak bone stress near the C4 screw during extension. However, during flexion and lateral bending, there was no significant difference in the peak bone stress near the C4 and C7 screws. During rotation, the difference between the peak bone stress near the C4 screw and that near the C7 screw showed that in the ACLP group, left rotation (37.6%) was similar to right rotation (36.7%), while in the ATPS group and ATPRS group, left rotation was lower than right rotation.Conclusion: Compared with the ACLP group, the ATPS group and ATPRS group have greater fixation stiffness and more stable fixation. However, in rotational movement, due to the uneven distribution of fixation stiffness, the stress distributio

Objective: To explore the clinical efficacy and safety of the "Three-Step Nine-Method Lumbar Correction" combined with physical therapy in the treatment of patients with degenerative lumbar spondylolisthesis(DLS).Methods: From January 2021 to December 2021, 72 patients diagnosed with DLS were enrolled and divided into the Three-Step Nine-Method Lumbar Correction group and the pelvic traction group, with 36 cases in each group. In the Three-Step Nine-Method Lumbar Correction group, there were 15 males and 21 females;aged 54 to 66 years old, with an average of (59.07±5.69) years old;the course of disease was 14 to 26 years old, with an average of (20.35±5.66) years old. They were treated with the Three-Step Nine-Method Lumbar Correction combined with low-frequency physical therapy, 3 times a week, for a 4-week course. In the pelvic traction group, there were 12 males and 24 females;aged 54 to 66 years old, with an average of (59.69±5.59) years old;the course of disease was 13 to 26 years old, with an average of (19.74±5.80) years old. They were treated with pelvic traction combined with low-frequency physical therapy. Efficacy evaluation was conducted using the visual analogue scale(VAS), Oswestry disability index(ODI), Japanese Orthopaedic Association (JOA) score, and Short Form 36 Health Survey (SF-36) before treatment, after 2 and 4 weeks of treatment, and at the 8-week follow-up after the end of treatment. In addition, imaging parameters of paravertebral muscles were evaluated before treatment and at the completion of treatment.Results: All 72 patients completed the follow-up for 8 weeks. At the 8-week follow-up after the end of treatment, in the Three-Step Nine-Method Lumbar Correction group, the VAS score for low back pain decreased from (6.25±1.23) points before treatment to (1.25±0.65) points, with a statistically significant difference (P<0.05);the ODI decreased from (57.17±7.13)% before treatment to (19.89±5.66)%, with a statistically significant difference (P<0.05);the JOA score and SF-36 score increased from (15.46±3.20) points and (35.25±9.28) points before treatment to (23.75±2.10) points and (62.31±13.03) points, respectively, with statistically significant differences (P<0.05). The improvement of each index in the Three-Step Nine-Method Lumbar Correction group was better than that in the pelvic traction group (P<0.05), but the change in imaging parameters was not significant (P>0.05). There was no statistically significant difference in the incidence of adverse reactions between the two groups (P>0.05), and no serious adverse events occurred.Conclusion: The Three-Step Nine-Method Lumbar Correction combined with physical therapy has a definite efficacy in the treatment of DLS. It can significantly relieve pain symptoms, improve physical function and patients' quality of life. Its effect is better than

目的：探讨“三步九法腰椎矫正”联合物理治疗退行性腰椎滑脱（DLS）的临床疗效和安全性。方法：选取2021年1月至2021年12月诊断为DLS的患者72例，分为三步九法腰椎矫正组和盆腔牵引组，每组36例。三步九法腰椎矫正组男性15例，女性21例；年龄54 ~ 66岁，平均（59.07±5.69）岁；病程14 ~ 26岁，平均（20.35±5.66）岁。采用三步九法腰椎矫正结合低频物理治疗，每周3次，疗程为4周。盆腔牵引组男性12例，女性24例；年龄54 ~ 66岁，平均（59.69±5.59）岁；病程13 ~ 26岁，平均（19.74±5.80）岁。盆腔牵引联合低频物理治疗。采用视觉模拟量表（VAS）、Oswestry残疾指数（ODI）、日本骨科协会（JOA）评分、SF-36健康问卷（SF-36）进行疗效评价，分别于治疗前、治疗后2周、4周及治疗结束后8周随访。此外，在治疗前和治疗结束时评估椎旁肌肉的影像学参数。结果：72例患者均完成随访8周。治疗结束后8周随访，三步九法腰椎矫正组腰痛VAS评分由治疗前的（6.25±1.23）分下降至（1.25±0.65）分，差异有统计学意义（PPPPP>0.05）。两组患者不良反应发生率比较，差异无统计学意义（P < 0.05），均未发生严重不良事件。结论：三步九法腰椎矫正配合物理疗法治疗腰椎间盘突出症疗效确切。能显著缓解疼痛症状，改善身体机能，提高患者生活质量。其效果优于盆腔牵引联合物理治疗，且安全性高。然而，其对椎旁肌肉的改善并不明显。

Objective: To explore the early clinical efficacy of a three-stage external treatment with traditional Chinese medicine (TCM) in the treatment of talar bone contusion caused by acute ankle sprain.Methods: A retrospective analysis was performed on 360 patients with primary lateral ankle sprain admitted from September 2021 to July 2024. Patients with talar bone contusion were selected based on MRI examination, and 73 cases were finally included. According to different treatment methods, they were divided into the observation group and the control group. The observation group consisted of 35 cases, including 16 males and 19 females, aged 24 to 37 years old with an average of (30.34±2.68) years old, and received the three-stage external TCM treatment combined with the "POLICE" protocol. The control group included 38 cases, including 18 males and 20 females, aged 24 to 35 years old with an average of (29.87±2.57) years old, and was treated with the "POLICE" protocol alone. The volume of bone marrow edema (BME) area shown by MRI before treatment and 6 weeks after treatment was measured using 3D Slicer software, and the BME improvement rate was calculated. The "Figure of 8" measurement method was used to assess ankle swelling before treatment and at 1 and 3 weeks after treatment. The visual analogue scale (VAS) was used to evaluate ankle pain before treatment and at 1 and 6 weeks after treatment. At 6 weeks after treatment, the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and Karlsson ankle function score system were used to evaluate the improvement of ankle function.Results: A total of 73 patients with talar bone contusion caused by ankle sprain completed the 6-week follow-up. At 6 weeks after treatment, the BME improvement rate in the observation group was (39.18±0.06)%, which was higher than (26.75±0.03)% in the control group, with a statistically significant difference (P<0.05). After 1 week of treatment, the VAS score in the observation group was (2.89±0.72) points, lower than (3.37±0.79) points in the control group, and the difference was statistically significant (P<0.05). The ankle swelling degree in the observation group was (50.20±3.19) cm, lower than (52.00±3.60) cm in the control group, with a statistically significant difference (P<0.05). After 3 weeks of treatment, there was no statistically significant difference in ankle swelling between the two groups. At 6 weeks after treatment, there was no statistically significant difference in VAS scores between the two groups. At 6 weeks after treatment, the AOFAS ankle-hindfoot score and Karlsson score in the observation group were (87.43±4.18) and (82.77±5.93) points, respectively, which were higher than (82.92±4.87) and (76.45±6.85) points in the control group, with statistically significant differences (P<0.05). According to the AOFAS ankle-hindfoot score, 8 cases were ex

Objective: To study the efficacy of lumbar oblique manipulation in the treatment of lumbar disc herniation with different herniation locations based on MSU classification.

Methods: A total of 272 patients with lumbar disc herniation who were treated from June 2023 to December 2023 were divided into central type group, paracentral type group, and far lateral type group. Among them, there were 73 cases in the central type group, including 41 males and 32 females, with an age of (46.39±6.89) years;161 cases in the paracentral type group, including 88 males and 73 females, with an age of (37.14±5.89) years;and 38 cases in the far lateral type group, including 22 males and 16 females, with an age of (28.56±4.89) years. The visual analogue scale (VAS) and straight leg raising angle of the three groups of patients before treatment, after treatment, and at 1 and 3 months after treatment were recorded, and inter-group, intra-group, and correlation comparisons were made.

Results: A total of 272 patients were followed up, with a follow-up time of (3.0±0.2) months. The VAS score of central type patients after treatment was 2(2, 3) points, which was lower than 4(3, 5) points before treatment, and the difference was statistically significant (P<0.05). There was no statistically significant difference between 1 month and 3 months after treatment and before treatment (P>0.05). The VAS score of paracentral type patients after treatment 2(2, 3) points and 1 month after treatment 3(2, 4) points were lower than that before treatment 5(4, 6) points, and the differences were statistically significant (P<0.05). There was no statistically significant difference in VAS between 3 months after treatment and before treatment (P>0.05). There were no statistically significant differences in VAS scores of far lateral type patients before treatment, after treatment, and at 1 and 3 months after treatment (P>0.05). The straight leg raising angle of central type patients after treatment 64(58, 69) and 1 month after treatment 58(52, 65) were significantly different from that before treatment 44(40, 51) (P<0.05);there was no statistically significant difference between 3 months after treatment and before treatment (P>0.05). The straight leg raising angle of paracentral type patients after treatment 61(55, 67)°, 1 month after treatment 61(53, 66)°, and 3 months after treatment 47(41, 56)° were significantly different from that before treatment 44(36, 52)° (P<0.05). There were no statistically significant differences in the straight leg raising angle of far lateral type patients before treatment, after treatment, and at 1 and 3 months after treatment (P>0.05). There was a correlation between VAS and straight leg raising angle in the three groups of patients, but there was no linear relationship.

Conclusion: Lumbar oblique manipulation

Objective: To explore the clinical efficacy of orthopedic manipulation combined with daoyin exercises in the treatment of chronic lumbar disc herniation under the guidance of the theory of "equal emphasis on muscles and bones".

Methods: A total of 60 patients with single-segment, unilateral chronic lumbar disc herniation from January 2023 to January 2024 were randomly divided into the traditional physical therapy group and the manipulation treatment group, with 30 cases in each group. Among them, 3 cases were lost to follow-up in the traditional physical therapy group and 2 cases in the manipulation treatment group. There were 27 cases in the traditional physical therapy group, including 15 males and 12 females, aged 25 to 65 years old with an average of (51.96±14.42) years;the course of disease ranged from 3 to 15 months with an average of (9.89±3.32) months;11 cases were on the left side and 16 cases on the right side;15 cases were at the L4, 5 segment and 12 cases at the L5S1 segment. They were treated with lumbar traction, medium-frequency electrical stimulation and ultrasonic therapy. There were 28 cases in the manipulation treatment group, including 14 males and 14 females, aged 24 to 68 years old with an average of (49.82±14.85) years old;the course of disease ranged from 3 to 14 months with an average of (9.61±3.05) months;15 cases were on the left side and 13 cases on the right side;17 cases were at the L4, 5 segment and 11 cases at the L5S1 segment. They were treated with orthopedic manipulation combined with daoyin exercises. The visual analogue scale (VAS), Oswestry disability index (ODI) and bilateral erector spinae muscle tone were compared between the two groups before treatment, after 2 weeks and 4 weeks of treatment.

Results: The two groups of patients were followed up and evaluated before treatment, 2 weeks and 4 weeks after treatment. The VAS of the manipulation treatment group and the traditional physical therapy group decreased from (5.46±0.99) and (5.41±1.05) points before treatment to (1.75±0.79) and (2.29±0.82) points after 4 weeks of treatment, respectively. Both groups were significantly improved after treatment compared with before treatment, and the differences were statistically significant (P<0.05);and the manipulation treatment group was better than the traditional physical therapy group at 4 weeks of treatment, with a statistically significant difference (P<0.05).

Objective: To explore the early efficacy and safety of hip arthroscopy in the treatment of patients with borderline developmental dysplasia of the hip(BDDH).

Methods: A total of 111 patients diagnosed with BDDH from January 2020 to December 2022 were selected and divided into two groups according to the surgical method. Among them, 63 patients who underwent arthroscopy were assigned to the arthroscopy group, including 22 males and 41 females with an average age of (35.67±6.83) years;48 patients who underwent periacetabular osteotomy were assigned to the PAO group, including 18 males and 30 females with an average age of (36.85±7.10) years. The operation time, hospital stay, blood loss, rehabilitation time, complication rate, and reoperation rate were recorded in both groups. Imaging indicators of the two groups were measured and recorded. The modified Harris hip score (mHHS), nonarthritic hip score (NAHS), and hip outcome score-activity of daily living scale (HOS-ADL) were used to evaluate hip function and quality of life before and after surgery.

Results: All patients were followed up for 12 months. The operation time (90.43±9.85) min, hospital stay(4.32±0.56) days, rehabilitation time (15.22±2.15) weeks, blood loss (25.69±6.57) ml, and number of complications (15 cases) in the arthroscopy group were all lower than those in the PAO group (117.25±15.83) min, (5.81±0.92) days, (21.10±3.74) weeks, (358.52±126.73) ml, 30 cases, with statistically significant differences (P<0.05). At the last follow-up after treatment, the lateral center edge angle (LCEA) (19.82±1.90)° and anterior center edge angle (ACEA) (20.01±1.85)° in the arthroscopy group decreased compared with those before treatment (21.43±2.10)°, (21.54±2.05)°, while in the PAO group, the LCEA (33.03±3.45)° and ACEA (33.48±4.22)° at the last follow-up after treatment increased compared with those before treatment, with statistically significant differences (P<0.05). The T?nnis angle in the arthroscopy group after treatment (11.05±1.83)° increased compared with that before treatment, while in the PAO group, the T?nnis angle at the last follow-up after treatment (2.98±0.75)° decreased compared with that before treatment, with statistically significant differences (P<0.05). In the arthroscopy group, the extrusion index (30.68±2.85) and T?nnis grade after treatment increased compared with those before treatment, while the α angle after treatment (38.79±4.27)° significantly decreased compared with that before treatment, with statistically significant differences (P<0.05);in the PAO group, the extrusion index (15.03±2.18) and α angle (53.58±6.02)° after treatment significantly decreased compared with those before treatment, with statistically significant differences (P<0.05). The mHHS score at the last follow-up after treatment in the arthroscopy group (86.41±7.33) was higher than that in the PAO g

目的：探讨髋关节镜治疗边缘性发育不良（BDDH）患者的早期疗效和安全性。方法：选取2020年1月至2022年12月诊断为BDDH的患者111例，根据手术方式分为两组。其中经关节镜检查的患者63例分为关节镜组，其中男性22例，女性41例，平均年龄（35.67±6.83）岁；48例行髋臼周围截骨术患者分为PAO组，其中男性18例，女性30例，平均年龄（36.85±7.10）岁。记录两组手术时间、住院时间、出血量、康复时间、并发症发生率、再手术率。测量并记录两组患者的影像学指标。采用改良Harris髋关节评分（mHHS）、非关节炎髋关节评分（NAHS）和髋关节结局评分-日常生活活动量表（HOS-ADL）评估手术前后髋关节功能和生活质量。结果：所有患者随访12个月。关节镜组手术时间（90.43±9.85）min、住院时间（4.32±0.56）d、康复时间（15.22±2.15）周、出血量（25.69±6.57）ml、并发症发生次数（15例）均低于PAO组（117.25±15.83）min、（5.81±0.92）d、（21.10±3.74）周、（358.52±126.73）ml、30例，差异有统计学意义（ppppppppppp）。与PAO相比，髋关节镜治疗BDDH患者的早中期临床疗效更好。但PAO在改善BDDH患者髋臼影像学指标方面更有优势，而髋关节镜只能改善患者的α角。同时，髋关节镜对患者的创伤较小，减少了出血量，更有利于患者的后续康复。

Objective: To explore the effect of nano-hydroxyapatite/collagen composite (nHAC) on bone graft fusion after anterior cervical discectomy and fusion (ACDF) in patients with cervical spondylosis and low bone mass.

Methods: A retrospective analysis was conducted on 47 patients with low bone mass who underwent ACDF from 2017 to 2021. They were divided into the nHAC group and the allogeneic bone group according to different bone graft materials. The nHAC group included 26 cases, with 8 males and 18 females;aged 50 to 78 years old with an average of (62.81±7.79) years old;the CT value of C₂-C₇ vertebrae was (264.16±36.33) HU. The allogeneic bone group included 21 cases, with 9 males and 12 females;aged 54 to 75 years old with an average of (65.95±6.58) years old;the CT value of C₂-C₇ vertebrae was (272.39±40.44) HU. The visual analogue scale (VAS), neck disability index (NDI), and Japanese Orthopaedic Association (JOA) spinal cord function score were compared before surgery, 1 week after surgery, and at the last follow-up to evaluate the clinical efficacy. Imaging assessment included C₂-C₇ Cobb angle, surgical segment height, intervertebral fusion, and whether the cage subsidence occurred at 1 week after surgery and the last follow-up.

Results: The follow-up duration ranged from 26 to 39 months with an average of (33.27±3.34) months in the nHAC group and 26 to 41 months with an average of (31.86±3.57) months in the allogeneic bone group. At 1 week after surgery and the last follow-up, the VAS, NDI scores, and JOA scores in both groups were significantly improved compared with those before surgery, with statistically significant differences (P<0.05). At 1 week after surgery, the C₂-C₇ Cobb angles in the nHAC group and the allogeneic bone group were (14.26±10.32)° and (14.28±8.20)° respectively, which were significantly different from those before surgery (P<0.05). At the last follow-up, the C₂-C₇ Cobb angles in both groups were smaller than those at 1 week after surgery, with statistically significant differences (P<0.05). At 1 week after surgery, the height of the surgical segment in the nHAC group was (31.65±2.55) mm, and that in the allogeneic bone group was (33.63±3.26) mm, which were significantly different from those before surgery (P<0.05). At the last follow-up, the height of the surgical segment in both groups decreased compared with that at 1 week after surgery, with statistically significant differences (P<0.05). At the last follow-up, 39 surgical segments were fused and 6 cages subsided in the nHAC group;40 surgical segments were fused and 7 cages subsided in the allogeneic bone group;there was no statistically significant difference between the two groups (P>0.05). Compared with the CT value of vertebrae without cage subsiden
