Background:
and Purpose In patients with large vessel occlusion (LVO), intravenous thrombolysis (IVT) frequently alters thrombus location; however, the clinical impact of this phenomenon remains unclear. We aimed to compare post-IVT thrombus dynamics between tenecteplase and alteplase and to evaluate the association between thrombus dynamics and 3-month outcomes.
Methods:
This retrospective study analyzed prospectively collected, multicenter data from consecutive patients with LVO who underwent bridging therapy between January 2022 and December 2024. Thrombus dynamics were classified as resolution, migration, or stability. Analyses incorporated propensity score matching with weighting to balance baseline characteristics.
Results:
Of the 806 initially included patients, 746 were included after matching (373 treated with tenecteplase and 373 treated with alteplase). The incidence of thrombus migration was significantly higher in the tenecteplase group than in the alteplase group (19.3% vs. 11.3%; odds ratio [OR]: 1.92; 95% confidence interval [CI] 1.27–2.91). The advantage of tenecteplase over alteplase was restricted to patients with an IVT-to-puncture time of <60 minutes (18.6% vs. 6.2%; p=0.001) and was no longer significant when the interval ≥60 minutes (19.7% vs. 15.0%; p=0.204; pinteraction=0.043). Additionally, thrombus migration was associated with a better functional outcome (OR: 1.62; 95% CI 1.04–2.53). Finally, tenecteplase was associated with improved functional independence compared with alteplase (OR: 1.43; 95% CI 1.04–1.95).
Conclusions
Tenecteplase demonstrated superior efficacy in inducing thrombus migration compared with alteplase, particularly within 60 minutes of IVT administration. Thrombus migration independently predicted improved functional independence. These findings support the preferential use of tenecteplase for bridging therapy in patients with LVO.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

Objective:To study the clinical outcome of palmar approach to on-top plasty in the treatment of unequal radial polydactyly.Methods:A retrospective analysis was conducted on patients with unequal radial polydactyly in which neither thumb duplicates possess both well-developed proximal and distal components. All the patients underwent palmar approach to on-top plasty between September 2013 and September 2023 at Shanghai Ninth People’s Hospital, Shanghai Jiao Tong University School of Medicine and Shanxi Children’s Hospital. At the final follow-up, the active flexion-extension range of motion of the first metacarpophalangeal and interphalangeal joints was measured, along with grip and pinch strength. The Vancouver scar scale was used to assess scar formation (total score 0-15, with higher scores indicating more severe scarring). Additionally, the pediatric quality of life inventory (total score 0-100, with higher scores indicating better quality of life, evaluated by the children themselves or by their parents/guardians on their behalf) and the satisfaction questionnaire (total score ranges from 1 to 5, with higher scores indicating greater satisfaction) were used to assess the patients’ daily quality of life and parents’satisfaction.Results:A total of 28 pediatric patients were included, comprising 15 males and 13 females, with an average age of 15 months (range: 10-36 months). All cases presented unilateral radial polydactyly, including 18 right hands and 10 left hands. The mean follow-up duration was 4.2 years (range: 1.5-6.0 years). All incisions healed in one stage, and the skin flaps survived well without infection. Joint stability was maintained without any deviation. All reconstructed thumbs demonstrated satisfactory aesthetic appearance. The reconstructed thumbs demonstrated mean active flexion-extension arcs of 76° (range 61°-85°) at the first metacarpophalangeal joint, and 42° (range 21°-65°) at the interphalangeal joint. The grip strength of the hand was 82% (63%-90%) of the normal opposite hand. The key, tip and tripod pinch strength were 76%(66%-83%), 77%(66%-85%) and 79%(68%-87%) of the normal opposite hand, respectively. No scar hyperplasia was found in all cases, and the Vancouver scar scale score was 1.2(0-3) points. The self-assessment score of the children on the pediatric quality of life inventory was 86 points, and the score of the parents/guardians was 91 points. In terms of family satisfaction, 23 patients scored 5, and 5 patients scored 4.Conclusion:The use of palmar approach to on-top plasty to treat unequal radial polydactyly can achieve functional and aesthetic results.
