Objective To assess the motor function of school-aged children with congenital muscular torticollis(CMT),and analyze the spatiotemporal parameters of their walking motion as well as the kinematic parameters of the trunk and lower limbs,so as to explore the potential long-term impact of CMT on the growth and development of children.Methods Using three-dimensional(3D)gait analysis technology,the gait of children with CMT was evaluated in detail and compared with that of normal children.The motion angles and ranges of the trunk,pelvis,hip,knee,and ankle joints,along with spatio-temporal parameters,were analyzed.Thirty-one children with CMT aged 6-12 years were recruited into the torticollis group,and 31 normal children of the same age range were included in the control group.The data of the torticollis group were divided into the healthy side and the affected side based on the side of the torticollis.Statistical analysis was performed among the three groups to calculate the differences in kinematic and spatio-temporal parameters.Results Compared with nomal children of the same age in the control group,significant differences were observed in the affected and unaffected sides of the torticollis group in terms of stride length,gait speed,percentage of support phase time,average ankle inversion angle during the swing phase,average ankle inversion angle during the support phase,average foot orientation angle during the support phase,average ankle internal rotation angle relative to the tibia during the stance phase,average knee valgus angle during the stance phase,average shoulder joint elevation,and shoulder joint height at landing.Specifically,the torticollis group had significantly lower stride length,gait speed,ankle inversion angle,knee valgus angle,and foot eversion angle in both the affected and unaffected sides compared to the control group,while the percentage of support phase time and the internal rotation angle of the foot relative to the tibia during the stance phase were higher than those in the control group.Conclusions For school-aged children with CMT,there are still residual manifestations of overall motor development abnormalities.These abnormalities also affect the non-affected side.Children with CMT have a relatively high risk of developing uneven shoulders,their overall walking efficiency is lower than that of normal children of the same age,and they exhibit lower limb motor abnormalities such as insufficient ankle joint stability.

Objective:To observe the effect of governor vessel(GV)electroacupuncture on potassium chloride cotransport-er 2(KCC2)and γ-Aminobutyric acid type a receptor(GABAAR α 1)and to explore the possible mecha-nism of GV electroacupuncture in improving post-stroke limb spasticity(PSLS).Method:45 male SD rats of SPF grade were randomly selected into the blank group and the sham operation group,with 9 rats in each group.The remaining rats were used to make the middle cerebral artery occlusion model.On the 3rd day after the completion of modeling,the rats with limb spasticity were chosen and random-ly divided into the model group,the electroacupuncture group,and the baclofen group,with 9 rats in each group,following a series of behavioral tests.Acupuncture was provided to the electroacupuncture group at"Da-zhui","Jizhong"and"Houhui",whereas the baclofen group received a baclofen solution by gavage for 7 days.Rats in each group were observed for the changes in nerve function by the symptom score of nerve function defect,and the changes in muscle tension level were evaluated by the modified Ashworth grading score and EMG signal value change.KCC2 and GABAARα1 mRNA and protein in the cerebral cortex of rats were de-tected by qPCR and Western Blot,and changes in chloride ion content were detected with a colorimetric kit.Result:The neurological function defect score,the modified Ashworth grading score,the water content of brain tissue,the volume of cerebral infarction,and the expression of chloride ion content in the model group were all significantly increased compared with the sham operation group at the same time point(P＜0.01),while the EMG signal value,cerebral cortex KCC2 and GABAAR α 1 mRNA and protein were significantly decreased(P＜0.01).Compared with the model group,the nerve function defect score,the modified Ashworth grading score,the water content of brain tissue,the volume of cerebral infarction and the expression of chlo-ride ion content in the electroacupuncture group and the baclofen group were all decreased(P＜0.01),while the EMG signal value and KCC2,with GABAARα1 mRNA and protein expression were all increased(P＜0.01,P＜0.05,respectively);There was no significant difference in all indexes between the GV electroacupuncture group and the baclofen group(P＞0.05).Conclusion:GV electroacupuncture can increase the expression of KCC2,GABAARα1 mRNA,and protein in the cerebral cortex of rats,in order to exert the inhibitory effect of γ-aminobutyric acid,thus improving the symptoms of PSLS.

Objective:To investigate the clinical efficacy of posterior midline incision combined with anteromedial approach in the treatment of complex olecranon fracture-dislocation.Methods:A retrospective analysis was performed on 26 patients (15 males and 11 females) with olecranon fracture-dislocation who were admitted from January 2020 to January 2024, including 5 cases of anterior transolecranon fracture-dislocation (2 cases of upper ulnar-radial joint dislocation), 21 cases of posterior transolecranon fracture-dislocation (5 cases of them were accompanied by upper ulnar-radial joint dislocation). Among them, there were 13 cases of traffic accidents, 7 cases of falling from heights, and 6 cases of walking falls. The average age is 45.1±15.3 years old (21-84 years old).Results:The operation time was 151.2±41.9 minutes, average tourniquet time was 93.7±22.6 minutes, and the intraoperative blood loss was 76.2±20.2 ml. The average follow-up was 16(12, 23) months, and the VAS score decreased significantly and the MEPS score increased significantly over time. At the last follow-up, the VAS score was 2(1, 2), and the MEPS score was 86.5±10.3, with 16 cases excellent, 7 cases good, and 3 cases medium, with an excellent rate of 89%. The range of motion of flexion-extension and pronation-supination were 119.3°±13.5°and 138.6°±15.2° respectively. Complications included 16 cases of ectopic ossification, of which 4 patients with significant effects on elbow function underwent surgical release 3-6 months after surgery. 1 case of ulnar nerve injury symptoms improved after emergency ulnar nerve release, and 1 case of elbow subluxation due to inaccurate coronoid process reduction and fixation. There were no serious complications such as vascular injury, internal fixation failure, fracture nonunion, and incision infection.Conclusion:The posterior midline incision combined with anteromedial approach can effectively treat complex olecranon fracture-dislocation and meet the requirements of early postoperative elbow rehabilitation.
