Objective: To explore clinical accuracy of remote sensing navigation alignment (RSNA) system in total knee arthroplasty (TKA) and its influence on postoperative clinical efficacy.
Methods: From May 2021 to May 2022, 60 knee osteoarthritis (KOA) patients with Kellgren-Lawrence (K-L) grade Ⅲ to Ⅳ treated by unilateral primary TKA were selected and divided into RSNA group and traditional operation group according to treatment methods, and 30 patients in each group. There were 6 males and 24 females in RSNA group, aged from 55 to 86 years old with an average of (68.06±8.23) years old;body mass index (BMI) ranged from 22.15 to 34.58 kg·m-2 with an average of (28.20±3.01) kg·m-2;the courses of disease ranged from 2 to 60 months with an average of (18.80±14.80) months;13 patients with grade Ⅲ and 17 patients with grade Ⅳ according to K-L grading. In traditional operation group, there were 8 males and 22 females, aged from 57 to 85 years old with an average of (67.26±6.32) years old;BMI ranged from 23.94 to 34.55 kg·m-2 with an average of (27.49±2.32) kg·m-2;the courses of disease ranged from 3 to 60 months with an average of (21.30±16.44) months;14 patients with grade Ⅲ and 16 patients with grade Ⅳ according to K-L grading. Western Ontario and McMaster Universities (WOMAC) osteoarthritis index and Knee Society score(KSS) were used to evaluate functional recovery of patients. Hip-knee-ankle angle (HKAA), distal femoral valgus angle (FVA) and distal fermoral flexion angle (DFFA) were measured before operation. HKAA and HKAA deviation angle were measured at 1 week after operation, and defective rate of lower limb force line, femur prosthesis valgus angle (FPVA) and femoral prosthesis flexion angle (FPFA), respectively, were calculated.
Results: There were no serious complications such as vascular and nerve injury during operation, and wound healed at stage Ⅰ. Both groups were followed up for 6 months. There were no significant difference in WOMAC index, KSS, HKAA, FVA and DFFA between two groups before operation (P>0.05). The force line defect rate, HKAA, HKAA deviation angle, FPVA deviation angle and FPFA of RSNA group were 6.7%, (178.74±1.56) °, (1.25±1.56) °, (1.84±0.16) ° and (4.85±2.46) °, respectively;while in traditional operation group were 20%, (176.73±3.46) °, (3.27±3.46) °, (2.44±0.26) °, (6.60±1.86) °;the difference between two groups were statistically significant (P<0.05). There were no significant difference in WOMAC index and KSS between two groups at 3 and 6 months after operation (P>0.05).
Conclusion: RSNA system could reduce defective rate of lower limb force line, FPVA deviation angle and FPFA after TKA, which is more accurate and easy to operate than traditional intramedullary localization surgery while ensuring postoperative efficacy.

Objective: To explore medium and long term efficacy of oblique lateral interbody fusion (OLIF) in treating lumbar specific infection.
Methods: From October 2017 to January 2021, 24 patients with lumbar specific infection were treated by OLIF combined with vertebral screw internal fixation, including 15 males and 9 females, aged from 27 to 61 years old with an average of (43.0±15.0) years old;the courses of disease ranged from 6 to 24 months with an average of (14.0±7.0) months;7 patients with L2-L3, 12 patients with L3-L4 and 5 patients with L4-L5;19 patients with tuberculosis infection and 5 patients with brucella infection. The amount of intraoperative blood loss, operative time and complications were recorded, and erythrocyte sedimentation rate(ESR), C-reactive protein (CRP), visual analogue scale (VAS), Japanese Orthopaedic Association(JOA) score and American Spinal Injury Association (ASIA) rating were compared before and one month after opertaion.
Results: All patients were followed up from 9 to 24 months with an average of (13.0±6.0) months. Operative time was (132.5±21.4) min, and intraoperative blood loss was (227.3±43.1) ml. ESR and CRP were decreased from (82.34±18.62) mmol·h-1 and (53.08±21.84) mg·L-1 before operation to (33.52±17.31) mmol·h-1 and (15.48±8.36) mg·L-1 at one month after operation, respectively (P<0.05). VAS was decreased from (7.52±1.36) before opertaion to (1.74±0.87) at one month after operation (P<0.05). JOA was increased from (17.86±3.95) before operation to (24.72±3.19) at one month after operation (P<0.05). Four patients had neurological symptoms before operation, and were classified to grade D according to ASIA classification, who were recovered to grade E at 1 month after operation. One patient was suffered from psoas major muscle injury after operation, and returned to normal at 3 weeks. One patient was suffered from abdominal distension and difficulty in defecation, and relieved after gastrointestinal decompression and enema. No complications such as abdominal organ injury and poor wound healing occurred in all patients.
Conclusion: OLIF combined with vertebral screw internal fixation is a new minimally invasive surgical method for the treatment of lumbar specific infection, especially the lesion located on the middle lumbar vertebra. It has advantages of less trauma, short operation time, less blood loss, convenient operation, complete removal of the lesion, safety and effectiveness, and has good medium-and long-term efficacy for lumbar specific infection.

Objective: To explore establishment and finite element analysis of personalized proximal clavicular anatomical plate screw fixation model.
Methods: A 40-year-old male healthy volunteer was selected and the finite element analysis modules of 3D reconstruction software Mimics 15.01, Hypermesh 2019 and Abaqus 2020 were used. The finite element model of anatomic plate at the proximal clavicle was established, and a vertical load of 250 N was applied to the distal end of long axis of clavicle about 15 mm, then the overall structure, plate and screw displacement cloud image, Mises stress distribution were observed.
Results: The displacement distribution of the overall structure shows the maximum displacement was distributed on the distal clavicle. Under the four conditions of normal upper limb weight, longitudinal clavicle fracture, oblique fracture and shoulder impact violence during fall, longitudinal clavicle fracture and oblique fracture, the maximum displacement were 1.04 mm, 1.03 mm, 1.35 mm and 1.33 mm, respectively. The displacement cloud map of titanium alloy steel plate showed the largest displacement was distributed near the distal clavicular bone, and the maximum displacement were 0.89 mm, 0.88 mm, 1.10 mm and 1.09 mm, respectively. The displacement cloud map of titanium alloy screw showed the largest displacement was distributed at the root of the distal screw, and the maximum displacement were 0.88 mm, 0.87 mm, 1.08 mm and 1.06 mm, respectively. Mises stress distribution showed the maximum stress was mainly distributed on titanium alloy plates and screws, and the stress on the clavicle was very small. Mises stress distribution cloud showed the maximum Mises stress was distributed at the second row of screw holes near the clavicle, and the maximum Mises stress were 673.1, 678.1, 648.5, 654.4 MPa, respectively. The maximum stresses of titanium alloy screws were 414.5, 417.4, 415.8 and 419.7 MPa, respectively.
Conclusion: The biomechanical changes of personalized proximal clavicular anatomical plates are demonstrated by using 3D finite element method to provide biomechanical data for personalized proximal clavicular anatomical plates.

Mongolian medicine external treatment, which called five kinds of treatment in ancient time, is a kind of external treatment including fire moxibustion, poultice, soaking and other therapies. The therapy was gradually developed and perfected in the course of Mongolian people's long-term struggle against diseases, which has characteristics of small trauma and suitable for long-term application. In this paper, the research progress of external treatment of orthopedic diseases in Mongolian medicine in recent years was summarized, and it was concluded that external treatment of orthopedic diseases in Mongolian medicine had distinct characteristics and accurate efficacy. However, there are still deficiencies in the standardization of clinical operation and the study of the mechanism of therapeutic action, which need further research and improvement.

Objective: To explore influencing factors of functional recovery after ankle fracture of typeⅡdegree and above supination-external rotation.
Methods: Clinical data of 120 patients with ankle fractures of typeⅡdegree and above supination-external rotation admitted from February 2019 to April 2021 were retrospectively analyzed. According to American Orthopaedic Foot and Ankle Society (AOFAS), patients were divided into excellent group with 73 patients (90 to 100 points), good group with 35 patients (75 to 89 points), and fair group with 12 patients(<50 points). The differences of ankle active range of motion (ROM) and AOFAS score were compared among three groups at the latest follow-up. Multivariate Logistic regression analysis was performed to analyze the factors related to functional recovery after ankle fracture of supination-external rotation.
Results: There were significant differences in postoperative ROM (dorsoextension, plantar flexion, varus and valgus) and complications between excellent group and good and acceptable group (P<0.05). Univariate analysis showed there were differences in age above 50 years old, Ⅳ degree of supination-external rotation fracture, lower tibiofibular ligament injury, posterior ankle fracture, no drainage tube placed, infection, antibiotic use time above 7 days (P<0.05). Multivariate Logistic regression analysis showed age above 50 years old[OR=2.829, 95%CI(1.049, 7.628), P=0.040], Ⅳ degree fracture of supination-external rotation[OR=6.13, 95%CI(1.153, 32.593), P=0.033], lower tibiofibular ligament injury[OR=10.785, 95%CI(3.338, 34.894), P=0.000], and posterior ankle fracture[OR=6.349, 95%CI(1.869, 21.560), P=0.003] were independent risk factors for functional recovery after ankle fracture of supination-external rotation (P<0.05).
Conclusion: The postoperative excellent outcome of ankle fracture was good, and the recovery of joint motion was better. The older age of patient, Ⅳ degree of supination-external rotation fracture, the lower tibiofibular ligament injury, and posterior ankle fracture are all adverse factors affecting functional recovery after supination-external rotation ankle fracture. In clinical, effective measures should be taken to deal with these influencing factors, and strive to improve the functional recovery after the operation of this type of fracture and reduce the occurrence of related complications.
