Abstract The prevention and control of myopia in Chinese children and adolescents has become a major public health issue. While maintaining increased outdoor activity as a cornerstone intervention, there is an urgent need to explore new complementary approaches that can be effectively implemented in both indoor and outdoor settings. In recent years, environmental spatial frequency has gained increasing attention as one of the key environmental factors influencing the development and progression of myopia. Both animal studies and human research have confirmed that indoor environments lacking mid to high spatial frequency components, often characterized as "visually impoverished", can promote axial elongation and myopia through mechanisms such as disruption of retinal neural signaling, impaired accommodative function, and altered expression of related molecules. Based on the scientific consensus, it is recommended that "enriching of environmental spatial frequency" should be integrated into the myopia prevention and control framework. Following the principles of schoolled organization, family cooperation, community involvement, and student participation, specific measures are put forward in three areas：optimizing school visual settings, improving home spatial environments, and promoting healthy visual behavior. The aim is to create "visually friendly" indoor environments as an important supplement to outdoor activity, thereby providing a novel perspective and strategy for comprehensively advancing myopia prevention and control among children and adolescents.

Objective To make a comparative analysis on mechancial properties of the modified cortical bone trajectory(MCBT)nailing technique using a novel variable-diameter screw and the traditional pedicle nailing technique using the cement-augmented pedicle screw(CAPS)in the L4 vertebral body.Merthods CAPS and MCBT instrumentation in the L4 vertebral body model were established by obtaining CT scan data from osteoporotic patients.The finite element method was used to compare the stability,screw axial pull-out force and lumbar spine motion under four working conditions(upper,lower,left and right loads)by using different nailing techniques.Results The axial pull-out force of the screws in MCBT group was 25.3％higher than that of the CAPS group(P＜0.05);the load-displacement ratios of the screws in MCBT group were 14.9％(P＞0.05),23.2％(P＞0.05),and 19.1％(P＜0.05)higher than those of CAPS group under the lower,left,and right working conditions,respectively;the load-displacement ratios of the screws in MCBT group were slightly lower than those of CAPS group under the upper working condition,but the differences were not statistically significant(P＞0.05);under the anterior and posterior flexion conditions,the lumbar spine motion of MCBT group was reduced by 13.3％and 2.5％,respectively,compared with CAPS group;under the left lateral bending,right lateral bending,and axial rotational conditions,the lumbar spine motion of MCBT group was improved by 69.1％,74.6％,and 118.1％,respectively,compared with CAPS group,but these differences were not statistically significant(P＞0.05).Conclusions MCBT screw was slightly better than CAPS in axial resistance to extraction force,and stability of vertebral anterior flexion under lower,left and right working conditions,and slightly weaker than CAPS in stability under upper,left lateral bending,right lateral bending,and axial rotational conditions.This study demonstrates that MCBT screw has certain advantages over CAPS,providing a pre-basic foundation for the clinical application of MCBT nailing technique for treating osteoporosis.

Objective To investigate the efficacy and safety of conventional open Latarjet surgery,arthroscopic Latarjet surgery,arthroscopic Bankart repair combined with Remplissage surgery in the treatment of recurrent anterior shoulder dislocation(RASD)with scapula glenoid bone defect>15%and meshing Hill-Sachs lesion.Methods The clinical data of 65 patients with RASD with 15%～25%scapula glenoid bone defect and meshing Hill-Sachs lesion admitted to our hospital from January 2022 to December 2024 were retrospectively analyzed.They were divided into group A,group B,and group C according to different surgical methods.Among them,group A underwent conventional open Latarjet surgery(n=18),group B underwent arthroscopic Latarjet surgery(n=21),and group C underwent arthroscopic Bankart repair combined with Remplissage surgery(n=26).The surgical conditions,preoperative and postoperative scores of related scales[visual analogue scale(VAS),Constant-Murley shoulder score,the University of California Los Angeles(UCLA)shoulder score],shoulder range of motion,postoperative complications and recurrence were compared among the three groups.Results Operation time:group B was longer than group A and group C(P<0.05),and group A was longer than group C(P<0.05).Intraoperative blood loss and hospital stay:group A was more or longer than group B and group C(P<0.05),group B was more or longer than group C(P<0.05).The VAS scores of the three groups at 1,6 and 12 months after operation were lower than those before operation(P<0.05).Pain VAS score at 1 and 6 months after operation:group A was higher than group B and group C(P<0.05).Pain VAS score at 1 month after operation:group B was higher than group C.Pain VAS score at 12 months after operation:there was no significant difference among the three groups(P>0.05).The UCLA shoulder scores of group A at 6 and 12 months after operation and group B and group C at 1,6 and 12 months after operation were higher than those before operation(P<0.05).UCLA score at 1 month after operation:group A0.05).The Constant-Murley scores of group A at 6 and 12 months after operation and group B and group C at 1,6 and 12 months after operation were higher than those before operation(P<0.05).Constant-Murley score at 1 month after operation:group A was lower than group B and group C(P<0.05).Constant-Murley score at 6 and 12 months after operation:three groups were equivalent(P>0.05).Forward flexion and lifting range of motion in the three groups:at 12 months after operation>before operation(P<0.05).Forward flexion and lifting range of motion was evaluated at 12 months after operation:there was no significant difference among the three groups(P>0.05).The range of motion of external rotation at body side and external rotation at 90° abduction before operation and at 12 months after operation:there was no significant difference between group A and group B(P>0.05).External rotation at body side and external rotation at 90° abduction of group C:at 12 months after operation of it was less than that before operation(P<0.05).The range of motion of external rotation at body side and external rotation at 90° abduction was obtained at 12 months after operation:group A and group B were greater than group C(P<0.05).Postoperative complication rate and recurrence rate:three groups were equivalent(P>0.05).Conclusion Conventional open Latarjet surgery,arthroscopic Latarjet surgery,arthroscopic Bankart repair combined with Remplissage surgery can effectively improve shoulder joint function and relieve pain in the treatment of RASD with 15%～25%scapula glenoid bone defect and meshing Hill-Sachs lesion.However,the two shoulder arthroscopic procedures are less traumatic and have faster postoperative recovery.

Objectives:To evaluate the difference in biomechanical properties of lumbar spine between tradi-tional trajectory(TT)and modified cortical bone trajectory(MCBT)pedicle screws in different osteoporotic condi-tions using finite element analysis.Methods:CT scanning was used to obtain lumbar spinal tomographic im-ages of osteoporotic patients,and then the L4 lumbar spine structure was reconstructed in three dimensions and validated.Two nail channels were constructed by varying the bone density as osteopenia(A1),moderate osteoporosis(A2),and severe osteoporosis(A3),respectively.One was a conventional double-threaded pedicle screw used in TT with a diameter of 6mm and an overall length of 45mm(TT group),the other was a vari-able-diameter,all-cortical bone threaded pedicle screw used in MCBT with a diameter of 4-5.5mm and an overall length of 45mm(MCBT group).The effects of the two designs on screw pullout resistance,stability(load-displacement ratio of upward,downward,left and right working conditions,defined as the ratio of load value to displacement when screw tail end displaced 0.1mm upward,downward,left and right towards its vertical axis)and lumbar spine mobility(when forward flexion,backward extension,lateral bending and axial rotation)were analyzed under different osteoporotic conditions.Results:In terms of axial pullout force,the MCBT group significantly improved 93.5％,96.5％,and 98.5％than the TT group in A1,A2,and A3,respec-tively.In terms of stability,at upward,downward,left,and right working conditions,the load-displacement ratios of the screws in the MCBT group were improved in comparison with the TT group in A1,A2,and A3,respectively,by 42.2％,40.8％,41.7％;49％,49％,51.5％;82.4％,81.5％,85.2％;73.1％,70.8％,72.5％.In terms of lumbar spine mobility,at forward flexion,under A1,A2,and A3,the TT group increased by 25％,26.6％and 28.7％compared to the MCBT group,respectively;at backward extension,the TT group increased by 24.5％and 22.9％compared to the MCBT group under A1 and A2,respectively,whereas under A3,the difference was not significant(P＞0.05);at lateral bending and axial rotation,the MCBT group had a slightly slight increase compared to the TT group under A1,A2,and A3(P＞0.05).Conclusions:Under different degrees of osteoporosis grading,MCBT technique was inferior in stability to TT technique only in spinal axial rotation and lateral flexion,while it outperformed TT technique in axial pull-out force,screw stability,and spinal stability during forward flexion and backward extension.
