OBJECTIVE: To evaluate the effectiveness of the channel-assisted minimally invasive repair (CAMIR) technique combined with flexor hallucis longus (FHL) tendon transfer in the treatment of Achilles tendon sleeve avulsion. METHODS: A retrospective analysis was conducted on 17 patients with Achilles tendon sleeve avulsion who underwent CAMIR technique combined with FHL transfer between January 2019 and January 2023. The cohort comprised 13 males and 4 females, aged 32 to 65 years (mean, 49.7 years). Etiologies included sports-related injuries in 15 cases and blunt trauma in 2 cases. The interval from injury to surgery ranged from 4 to 368 days (median, 15 days). All patients exhibited calcification at the Achilles tendon insertion site, with 7 cases complicated by Haglund deformity. Postoperative complications were meticulously monitored, and tendon healing was assessed via MRI. Clinical outcome were evaluated using the visual analogue scale (VAS) score for pain, Tegner activity level rating scale, ankle activity score (AAS), American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score, Victorian Institute of Sport Assessment-Achilles (VISA-A) score, and subjective clinical scoring systems preoperatively and at last follow-up. RESULTS: The operation time was 50-62 minutes (mean, 56 minutes), and the intraoperative blood loss was 5-50 mL (mean, 19.7 mL). All patients were followed up 12-67 months (mean, 38 months). No postoperative complication, such as Achilles tendon re-rupture, incision infection, deep vein thrombosis, heel raise insufficiency, or sural nerve injury, was observed. At last follow-up, MRI examination confirmed satisfactory tendon healing in all cases. Significant improvements were noted in VAS scores, Tegner activity level rating scale, AAS scores, AOFAS ankle-hindfoot scores, and VISA-A scores compared to preoperative ones ( P<0.05). At last follow-up, the subjective clinical score ranged from 6 to 10 (median, 9). CONCLUSION The CAMIR technique combined with FHL tendon transfer is a good treatment for repair of Achilles tendon sleeve avulsion, with good recovery of ankle function and few complications.

OBJECTIVE: To evaluate the positional relationship between protective channel and sural nerve while treating acute Achilles tendon rupture with channel assisted minimally invasive repair (CAMIR) technique based on anatomical observations of cadaver specimens. METHODS: Twelve adult cadaveric lower limb specimens (6 left, 6 right) were utilized. A CAMIR device was implanted at a distance of 4 cm from the proximal end of the specimen to the Achilles tendon insertion. The skin was incised along the tendon's medial side, the sural nerve was dissected, and the positional relationship with the protective channel was observed. The distance from the sural nerve-Achilles tendon intersection to the calcaneal insertion, the vertical distance between protective channel and the calcaneal insertion, and the horizontal distance between the sural nerve and protective channel were measured by using vernier caliper. RESULTS: Anatomical examination demonstrated a variable positional relationship between the sural nerve and protective channel, with the sural nerve positioned above (8 specimens) or below (4 specimens) the protective channel. The distance from the sural nerve-Achilles tendon intersection to the calcaneal insertion was (105.67±14.94) mm, the vertical distance between protective channel and the calcaneal insertion was (93.20±9.57) mm, and the horizontal distance between the sural nerve and protective channel was (0.31±0.14) mm. CONCLUSION The use of CAMIR technique for the treatment of acute Achilles tendon rupture can effectively avoid iatrogenic injury to the sural nerve.

OBJECTIVE: To explore the difference in effectiveness between a dynamic rehabilitation protocol and a traditional static rehabilitation protocol after the treatment of acute Achilles tendon rupture with channel assisted minimally invasive repair (CAMIR) technique through a prospective comparative trial, aiming to provide a reference for clinically selecting a feasible treatment regimen. METHODS: Patients with acute Achilles tendon rupture admitted between June 2021 and June 2022 were included in the study, with 60 patients meeting the selection criteria. They were randomly divided into a dynamic rehabilitation group ( n=30) and a static rehabilitation group ( n=30) using a computer-generated random number method. There was no significant difference in baseline data such as gender, age, body mass index, smoking history, injured side, cause of injury, and disease duration between the two groups ( P>0.05). After Achilles tendon anastomosis by using CAMIR technique, the dynamic rehabilitation group implemented early partial weight-bearing training with the assistance of an Achilles heel boot and controlled ankle joint exercises for 6 weeks, while the static rehabilitation group maintained a non-weight-bearing status during this period. Complications in both groups were recorded. At 3 and 6 months after operation, the Achilles tendon total rupture score (ATRS) was used to evaluate the degree of functional limitation of the Achilles tendon in the affected limb, and the 12-Item Short Form Health Survey (SF-12 scale) was used to assess the patients' quality of life, including physical component summary (PCS) and mental component summary (MCS) scores. RESULTS: No sural nerve injury occurred during operation in both groups. All patients were followed up 12-18 months (mean, 14 months). The dynamic rehabilitation group had significantly higher ATRS scores at 3 and 6 months after operation compared to the static rehabilitation group ( P<0.05). At 3 months after operation, the dynamic rehabilitation group had significantly lower PCS, MCS, and SF-12 total scores compared to the static rehabilitation group ( P<0.05). At 6 months, all quality of life scores in the two groups were similar ( P>0.05). Two cases (6.6%) in the dynamic rehabilitation group and 5 cases (16.7%) in the static rehabilitation group developed complications, with no significant difference in incidence of complications ( P>0.05). CONCLUSION For acute Achilles tendon rupture, the dynamic rehabilitation protocol after Achilles tendon anastomosis by using CAMIR technique can improve early functional recovery and maintains comparable safety and effectiveness compared to static rehabilitation.

OBJECTIVE: To investigate the early effectiveness of transiliac-transsacral screws internal fixation assisted by augmented reality navigation system HoloSight (hereinafter referred to as "computer navigation system") in the treatment of posterior pelvic ring injuries. METHODS: A retrospective analysis was made in the 41 patients with posterior pelvic ring injuries who had been treated surgically with transiliac-transsacral screws between June 2022 and June 2023. The patients were divided into navigation group (18 cases, using computer navigation system to assist screw implantation) and freehand group (23 cases, using C-arm X-ray fluoroscopy to guide screw implantation) according to the different methods of transiliac-transsacral screws placement. There was no significant difference in gender, age, body mass index, causes of injuries, Tile classification of pelvic fracture, days from injury to operation, usage of unlocking closed reduction technique between the two groups ( P>0.05). The time of screw implantation, the fluoroscopy times, the guide wire adjustment times of each screw, and the incidence of complications were recorded and compared between the two groups. The position of the transiliac-transsacral screw was scanned by CT within 2 days after operation, and the position of the screw was classified according to Gras standard. RESULTS: The operation was successfully completed in both groups. The time of screw implantation, the fluoroscopy times, and the guide wire adjustment times of each screw in the navigation group were significantly less than those in the freehand group ( P<0.05). There were 2 cases of incision infection in the freehand group, and the incision healed by first intention after active dressing change; there was no screw-related complication in the navigation group during operation and early period after operation; the difference in incidence of complications between the two groups (8.7% vs. 0) was not significant ( P=0.495). According to the Gras standard, the screw position of the navigation group was significantly better than that of the freehand group ( P<0.05). CONCLUSION Compared with the traditional freehand method, the computer navigation system assisted transiliac-transsacral screws internal fixation in the treatment of posterior pelvic ring injuries has advantages of improving the accuracy of screw implantation and reducing radiation damage and the time of screw implantation.

Objective:To investigate the long-term survival and safety in patients with muscle-invasive bladder cancer (MIBC) who experienced a noninvasive down-staging (≤pT 1)after transurethral resection of bladder tumor (TURBT) plus systemic chemotherapy and received bladder-sparing treatment. Methods:The records of patients with MIBC who underwent maximal TURBT plus systemic chemotherapy-guided bladder-sparing treatment were reviewed retrospectively from Dec 2013 to Dec 2020. Eventually, 22 patients who achieved noninvasive down-staging underwent conservative management. The total patient cohort contained 10 males and 12 females. A majority of patients had single lesion and stage T2 disease. The median age of the patients was 66 years and the median tumor size was 3.0 cm. All patients underwent maximal TURBT to resect all visible diseases and followed by 3-4 cycles platinum-based systemic chemotherapy. After achieving noninvasive down-staging, 14 patients received concurrent chemoradiotherapy, and the other 8 patients underwent surveillance. Overactive bladder symptom score (OABSS) was used to assess the bladder function after treatment.Results:Twelve patients achieved pT 0 and 10 patients were down-staged to cT a-T 1. At a median follow-up of 36.7 months, 90.9%(20/22) patients retained their bladder function successfully. Among the 14 patients who received concurrent chemoradiotherapy, 4 had grade 3 or 4 adverse events. Among the 8 patients who underwent surveillance, 3 had grade 3 or 4 adverse events after systemic chemotherapy.Nine patients experienced tumor recurrence in the bladder, and 2 patients died of bladder cancer. Seven (31.8%) patients experienced Ⅲ/Ⅳ grade complications. The 5-year recurrence-free survival (RFS) and overall survival (OS) in patients achieved pT0 were 66.7% and 100.0%, respectively. The 5-year RFS and OS in patients achieved cTa-T1 were 40% and 72%, respectively. The OABSS score of 20 patients who retained their bladder successfully was (1.00±1.03). Conclusions:MIBC patients who achieved noninvasive down-staging might be candidates for the bladder-sparing treatment with maximum TURBT followed by systemic chemotherapy.The patients who achieved pT 0 might have better prognosis with functional bladder.

Objective: To investigate adolescent haze weather health protection behavior, and to provide scientific basis for behavioral intervention and health guidance for adolescents in haze weather. Methods: From June 2015 to April 2016, 1 025 adolescents were selected from 22 classes in two middle schools of Baoding City, Hebei Province, by stratified cluster sampling method. General information questionnaire and the Brief Haze Weather Health Protection Behavior Assessment Scale Adolescent Version (BHWHPBAS AV) were used. Multiple linear regressions were conducted to explore factors affecting adolescent haze weather health protection behavior. Different models were used to confirm associations between influencing factors and BHWHPBAS AV scores. Results: Adolescents had a low overall score of BHWHPBASAV (45.81±13.16). The score rate of self adjustment after haze weather was the highest (64.54%). The score rate of obtaining relevant knowledge before haze weather was the lowest (50.28%). Compared with adolescents in urban area, rural adolescents had a lower BHWHPBAS AV score ( β=-3.20, P <0.01). Compared with students (living with parents), those living without parents had a lower BHWHPBAS AV score ( β=-4.16, P =0.01). Compared with students never receive physical examination,those had received physical examination during the past years had a higher BHWHPBAS AV score ( β=4.44，5.66，9.04, P <0.01). Compared with students with no knowledge of respiratory system diseases, those with moderate to sufficient knowledge had a higher BHWHPBAS AV score ( β=9.34，12.19，P <0.01). These associations were stable and consistent.Multiple linear regression analysis showed that residence, residence with parents, physical examination and knowledge of respiratory diseases were the relevant factors of BHWHPBAS AV score ( P <0.05). Conclusion Adolescent haze weather health protection behavior level is low and is affected by many factors. Cooperation should be strengthened to conduct behavioral interventions and health guidance on haze health protection for adolescents, so as to promote healthy growth of adolescents.

Purpose: Reduced quality of life after cystectomy has made bladder preservation a popular research topic for muscle-invasive bladder cancer (MIBC). Previous research has indicated significant tumor downstaging after neoadjuvant chemotherapy (NAC). However, maximal transurethral resection of bladder tumor (TURBT) was performed before NAC to define the pathology, impacting the real evaluation of NAC. This research aimed to assess real NAC efficacy without interference from TURBT and apply combined modality therapies guided by NAC efficacy. Materials and Methods: Patients with cT2-4aN0M0 MIBC were confirmed by cystoscopic biopsy and imaging. NAC efficacy was assessed by imaging, urine cytology, and cystoscopy with multidisciplinary team discussion. Definite responders (≤ T1) underwent TURBT plus concurrent chemoradiotherapy. Incomplete responders underwent radical cystectomy or partial cystectomy if feasible. The primary endpoint was the bladder preservation rate. Results: Fifty-nine patients were enrolled, and the median age was 63 years. Patients with cT3-4 accounted for 75%. The median number of NAC cycles was three. Definite responders were 52.5%. The complete response (CR) was 10.2%, and 59.3% of patients received bladder-sparing treatments. With a median follow-up of 44.6 months, the 3-year overall survival (OS) was 72.8%. Three-year OS and relapse-free survival were 88.4% and 60.0% in the bladder-sparing group but only 74.3% and 37.5% in the cystectomy group. The evaluations of preserved bladder function were satisfactory. Conclusion After stratifying MIBC patients by NAC efficacy, definite responders achieved a satisfactory bladder-sparing rate, prognosis, and bladder function. The CR rate reflected the real NAC efficacy for MIBC. This therapy is worth verifying through multicenter research.
