Objective:To evaluate the clinical efficacy of percutaneous channel screwing assisted by the robot navigation positioning system combined with pelvic unlocking reduction frame for pelvic fractures.Methods:A retrospective analysis was conducted of the 12 patients with pelvic fracture who had been admitted to Department of Orthopaedics, The First Affiliated Hospital to Anhui Medical University from January to October 2018. They were 7 men and 5 women with an average age of 42.3 years (from 25 to 62 years). The time from injury to operation averaged 5.1 days (from 2 to 10 days). There were 2 cases of type B1, 5 ones of type B2 and 5 ones of type C1 according to the Tile classification. After closed reduction using the pelvic unlocking reduction frame, the orthopedics robot navigation positioning system was used to guide the placement of percutaneous screws. The posterior rings were fixated with sacroiliac screws, and the anterior rings with pubis screws, pubic symphysis screws or external fixation. The placement time for each screw, fluoroscopy frequency, reduction quality, fracture union time, function of the affected hip and complications at the final follow-up were recorded.Results:A total of 25 percutaneous screws were inserted in the 12 patients with a mean fluoroscopic frequency of 4.7 times (from 3 to 8 times) and a mean placement time of 14.9 min (from 12 to 20 min). According to the Matta rating system, the fracture reduction was rated as excellent in 7 cases, as good in 4 and as fair in one. The average follow-up time was 11.3 months (from 6 to 16 months). All fractures healed after an average period of 11.8 weeks (from 10 to 14 weeks). By the Majeed scoring, the pelvic function at the final follow-up was excellent in 8 cases and good in 4. The follow-ups observed no infection, nerve injury, deep vein thrombosis, heterotopic ossification, implant looseningor traumatic arthritis in these patients.Conclusion:Percutaneous channel screwing assisted by the robot navigation positioning system combined with pelvic unlocking reduction frame can reduce operative time and risks and lead to minimal invasion for pelvic fractures.

Acetabular both-column fractures, the most complex type in acetabular fractures, are usually caused by high-energy violence, accounting for 20% of all the acetabular fractures. Most of them need surgical treatment. Because fracture fragments in the posterior column are various, controversy exists in the treatment of the posterior column. This article summarizes the modes of exposure and internal fixation, like anterior approach, posterior approach, screwing and plating, for the posterior column injury in the acetabular both-column fractures, hoping to help proper clinical choice of the modes.

Objective To explore the importance of high-quality nursing in the process of wavefront aberration test. Methods This study retrospectively analyzed the nursing cooperation in 16 patients (32 eyes) during their wavefront aberration test. Results The uncorrected visual acuity ( UCVA ) in 15 patients of 16 patients reached more than 1. 0 both in one month and 6 months after the surgery; the post-operation refraction were less than 0. 5D with expected refraction; none of the 16 patients′ best corrected visual acuity ( BCVA) reduced after surgery. Conclusions The accuracy of data collection of wavefront aberration test is the foundation for excimer laser and high-quality nursing plays an important role in the test.

Objective To observe the nursing efficacy for myopic patients with high cornea curvature undergoing laser-assisted insight keratomileusis ( LASIK ) . Methods We retrospectively analyzed the nursing experience and surgery cooperation during LASIK for 35 myopic patients with pure high cornea curvature, including pre-operation examination, pre-operation preparation, cooperativeness during surgery, and post-operative nursing instruction. We also compared the pre-operation and post-operation anterior corneal surface elevation and posterior corneal surface elevation. Results All 35 patients had achieved their pre-operation best corrected visual acuity, without cornea staphyloma. The long-term efficacy needed to be follow-up in further study. Conclusions LASIK has shown safety and efficacy for myopic patients with high cornea curvature, and the success of which not only depended on the skill of the surgeon, but also on the peri-op nursing.

Objective:To explore the role of metagenomic next-generation sequencing (mNGS) in the diagnosis of pathogens in primary infectious diseases of the spine (IDS) and to reveal its pathogen spectrum.Methods:This is a retrospective multi-center case series study. Clinical data of 380 patients with primary IDS who were treated at four medical centers in China from December 2019 to April 2024 were retrospectively analyzed. Among them, 82 cases were from the Department of Spine Surgery at the Affiliated Hospital of Qingdao University, 129 cases were from the Orthopedics Section Ⅱ (Bone Infection), Public Health Clinical Center Affiliated to Shandong University, 112 cases were from the Department of Spine Surgery, Fuzhou Second General Hospital, and 57 cases were from the Department of Orthopedic Surgery, Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine. There were 238 males and 242 females, with an age of (61.4±13.1) years (range: 10 to 91 years). Specimens from the site of spinal infection were obtained for pathogen culture, pathological examination, and mNGS detection preoperatively or intraoperatively in all patients. The number, types, and positive rates of pathogens detected by the two methods were analyzed and compared using the Chi-square test.Results:Among the 380 patients, 320 had confirmed pathogenic bacteria, with the highest proportion being pyogenic bacterial infections, accounting for 76.9% (246/320). The most common pathogen was Staphylococcus aureus, accounting for 22.8% (73/320). Brucella accounted for 13.8% (44/320); Mycobacterium tuberculosis accounted for 6.3% (20/320). Fungal infections accounted for 3.4% (11/320), mainly Aspergillus and Candida. In addition, Mycoplasma was detected in 3 cases (0.9%) and Benacox body in 4 cases (1.2%). The pathogen spectrum constructed by mNGS covered 46 types of pathogens, higher than the 22 types detected by traditional methods. The positive rate of mNGS was 80.8% (308/381), significantly higher than the 27.9% (106/381) of traditional methods ( χ2=182.53, P<0.01). Conclusions:mNGS improves the positive rate of pathogen diagnosis in IDS, detecting a broader spectrum of pathogens, and serves as a valuable complement to traditional diagnostic methods. Combining both methods in the diagnosis of IDS can maximize detection rates, providing robust evidence for precise anti-infective treatment.

Objective:To investigate the effect of Ilizarov bone transport technique combined with vancomycin bone cement for treatment of posttraumatic tibial bone infection combined with bone and soft tissue defects.Methods:A retrospective case series study was performed on 11 patients with posttraumatic tibial bone infection combined with bone and soft tissue defects admitted to First Affiliated Hospital of Anhui Medical University from June 2016 to June 2019.There were 7 males and 4 females, with age of 21-56 years [(41.5±12.1)years]. After debridement, the length of bone defect was 4-13.2 cm [(8.1±2.6)cm], and the area of soft tissue defect was 6.5-23.4 cm 2 [(16.2±4.7)cm 2]. All patients were treated firstly with debridement of bone infection and vancomycin loaded bone cement pad filling, followed by Ilizarov technique to repair bone and soft tissue defects. The soft tissue docking time, fracture docking time, external fixation time and external fixation index were recorded. At the last follow-up, Johner wruhs score was used to evaluate the curative effect and American Orthopedic Foot and Ankle Society (AOFAS) ankle hindfoot score to evaluate the ankle joint function. The postoperative complications were observed. Results:All patients were followed up for 17-23 months [(17.9±4.5)months]. The soft tissue docking time was 48-155 days [(101.7±29.0)days] and fracture docking time was 55-167 days [(111.6±29.5)days]. The external fixation time was 154-450 days [(322.9±86.3)days] with an external fixation index of 31.1-61.5 cm/day [(40.8+ 7.5)cm/day]. At the last follow-up, the results were excellent in 2 patients, good in 4 and fair in 5 based on Johner-Wruhs score. At the last follow-up, the AOFAS ankle hindfoot score was 61-94 points [(76.6±12.7)points], with excellent results in 3 patients, good in 2 and fair in 6. Four patients were treated with secondary operation, and two of them bad docking site nonunion which healed after secondary bone grafting. No free or local transposition flap repair was performed in regardless of soft tissue defect. During the follow-up, there were no complications such as fever, wound weeping, soft tissue necrosis or neurovascular injury.Conclusion:For posttraumatic tibial bone infection combined with bone and soft tissue defects, the Ilizarov bone transport technique combined with vancomycin-loaded bone cement has advantage of shorter operation time, trauma and complications, and can achieve bone lengthening and soft tissue healing simultaneously.

OBJECTIVE: To explore the reduction and support effect of the subchondral screw compression technique for residual or secondary collapse of the lateral tibial plateau during operation. METHODS: Between January 2020 and June 2021, 11 patients with residual or secondary collapse of the lateral tibial plateau during operation were treated with the subchondral screw compression technique. There were 6 males and 5 females, aged 52.3 years old (range, 27-64 years). The fractures were caused by traffic accident in 10 cases and falling from height in 1 case and located at the left knee in 6 cases and the right knee in 5 cases. According to Schatzker classification, there were 5 cases of type Ⅱ fractures, 4 cases of type Ⅲ fractures, and 2 cases of type Ⅴfractures. According to the three columns classification, there were 5 cases of lateral column, 4 cases of lateral column and posterior column, and 2 cases of three columns. The time from injury to operation was 4.5 days (range, 3-7 days). During the follow-up, X-ray films were obtained and the Rasmussen standard was used to evaluate the quality of fracture reduction, meanwhile fracture healing was observed. The medial proximal tibial angle (mPTA), posterior tibial slope angle (pTSA), and articular surface collapse were measured at immediate and 12 months after operation. The knee joint range of motion was evaluated at last follow-up, and the knee joint function was evaluated using the Hospital for Special Surgery (HSS) score. RESULTS: All operations were successfully completed, with a mean operation time of 71.4 minutes (range, 55-120 minutes), and a mean hospital stay of 8.0 days (range, 5-13 days). The incisions all healed by first intention, without complications such as infection, flap necrosis, or vascular and nerve injury. All patients were followed up 16.5 months on average (range, 12-24 months). X-ray films showed that the fracture reduction score was 14-18 (mean, 16.7) according to Rasmussen score criteria; and 5 cases were rated as excellent and 6 as good. All fractures healed clinically with a mean clinical healing time of 14.9 weeks (range, 12-16 weeks), and there was no complications such as plate or screw loosening. At 12 months after operation, the mPTA and pTSA were (87.5±1.7)° and (6.2±3.1)°, respectively; there was no significant difference when compared to the values at immediate after operation [(87.6±1.8)° and (6.5±3.1)°] ( P>0.05). The articular surface of the tibial plateaus was effectively supported, and it collapsed again by 0-1.0 mm at 12 months, with an average of 0.4 mm. At last follow-up, the knee joint range of motion was 115°-135° (mean, 126.8°) and the HSS score for knee joint function was 87-98 (mean, 93.9). Five patients underwent secondary operation to remove the internal fixator at 12-18 months after operation. CONCLUSION The subchondral screw compression technique is helpful for the reduction of residual or secondary collapse of the lateral tibial plateau during operation, and can provide good support for osteochondral blocks.

Background The contracted family doctor services are the embodiment of the implementation of the new medical reform policy, and the transformation of the grass-roots health service mode. Studies have proved that the occupational stress in medical staff was at a high level. The enhancement of professional identity will contribute to strengthen team building，alleviate job burnout, and reduce turnover intention of family doctors. Objective To investigate the current situation of occupational identity among family doctor teams in Chengdu, to examine potential influencing factors of occupational identity, and to provide a reference for promoting career development and team building of family doctor teams. Methods Multi-stage random cluster sampling was adopted to enroll study participants form 46 primary healthcare centers where family doctor contract services were implemented among 23 districts and counties in Chengdu between March 4 and 26, 2021. A total of 2 681 family doctors participated in this survey. A self-reported survey was conducted to collect participants' demographic and occupational data. The Effort-Reward Imbalance (ERI）questionnaire was implemented to assess occupational stress. The Professional Identity Scale was used to appraise occupational identity. Results A total of 2 327 valid questionnaires were collected, with a valid recovery rate of 86.80%, involving 1 715 females (73.7%) and 612 males (26.3%), with dominant age groups of 26−35 years (43.3%) and 36−45 years (30.4%), a high proportion of being married (82.8%), having college (36.0%) and undergraduate (47.3%) education, a high proportion of primary titles (66.0%) and informal work contract (66.1%). About 88.7% of family doctor team workers reported occupational stress. The average score of occupational identity was (3.68±0.62) points. There were significant differences in occupational identity scores among different professional title, work contract, working years in medical institutions, income, and effort/reward ratio (EER) groups (P < 0.05). ERR was negatively correlated with occupational identity (r_s=−0.495, P<0.05）. The multiple regression model showed that occupational identity score in the non-staffed participants was lower than the score in the staffed ones (OR=0.429, 95%CI: 0.299−0.825). The occupational identity score in the participants having associate senior title or above was higher than in without professional title (OR=1.424, 95%CI: 1.194−2.328). The longer the working years, the higher the occupational identity score among the participants. The score of the more than 20 working years group was 1.820 times that of the less than 5 working years group (95%CI: 1.342−2.543). The higher the income, the higher the occupational identity score. The score of the 9001−12000 yuan per month group was 1.977 times that of the 1000−3000 yuan per month group (95%CI: 0.811−9.696) , and the score of the more than 12000 yuan per month group was 2.283 times that of the 1000−3000 yuan per month group (95%CI: 1.199−10.267）. Conclusion The family doctor team workers generally report occupational stress, and their occupational identity is at a medium level in Chengdu. Relevant managers should implement intervention measures against the main influencing factors to reduce their work tension and improve their occupational identity.
