Objective Toobserve the clinical efficacy of arthroscopic superior fulcrum reconstruction versus superior capsule reconstruction in the treatment of irreparable massive rotator cuff tears,in order to provide more therapeutic choices.Methods A total of 28 patients with irreparable massive rotator cuff tears,who had been admitted to the Department of Orthopedics,the Third Affiliated Hospital of Anhui Medical University from September 2021 to July 2023 were selected,14 of whom underwent arthroscopic superior fulcrum reconstruction(superior fulcrum reconstruction group)and 14 underwent arthroscopic superior capsule reconstruction(superior capsule reconstruction group).The observation indexes were operative time,intraoperative blood loss,shoulder joint active range of motion,the university of California at Los Angeles shoulder rating scale(UCLA),American Shoulder and Elbow Surgeons' score(ASES),the shoulder score of Constant-Murley(CMS)and Visual Analogue Scale(VAS).Results All patients had a successful surgery and a postoperative follow-up was at least 12 months.The postoperative shoulder joint active range of motion,UCLA,ASES and CMS between the two groups,which were statistically significant(P＜0.05),superior fulcrum reconstruction group was better than superior capsule reconstruction group.There was no significant difference in postoperative VAS,operative time or intraoperative blood loss between the two groups(P＞0.05).Conclusions Arthroscopic superior fulcrum reconstruction outper-forms superior capsule reconstruction in the treatment of irreparable massive rotator cuff tears.

Objective To investigate the radiographic anatomical relationship between tibial plateau and distal femur and evaluate the impact of reset tibial plateau of various widths after reduction of the Schatzker Ⅳ-C tibial plateau fractures on postoperative outcomes.Methods We collected and reviewed the X-ray images of the normal knees of 207 standard neutrally-positioned adults(non-fracture group)and pre-and post-operative immediate anterior-posterior X-ray images of the knees of 60 patients with Schatzker Ⅳ-C fractures(fracture group)in our hospital from August 2012 to August 2022.We measured the proximal tibial joint width(TAW),distal femoral width(DFW),and distal femoral joint width(FAW)in both groups and calculated the TAW/DFW and TAW/FAW ratios.In the fracture group,the cases with TAW between FAW and DFW were assigned to the well-reduced group,while those with TAW outside this range between FAW and DFW to the poorly-reduced group.Both groups were assessed using the Hospital for Special Surgery knee score(HSS)one year after operation.Results In the non-fracture group,there were no significant differences in gender or affected side in terms of TAW/DFW and TAW/FAW ratios(P＞0.05),while in the fracture group,there were statistically significant differences in the TAW/DFW and TAW/FAW ratios compared to the non-fracture group(P＜0.05).There was a statistically signifi-cant difference in the one-year postoperative HSS scores between the well-reduced and poorly-reduced groups in the fracture group(P＜0.05).Conclusion The radiographic anatomical relationship between the tibial plateau and distal femur in normal adults is relatively constant,providing a radiological reference for resetting the tibial plateau to a satisfactory width during reduction of Schatzker Ⅳ-C fractures.TAW/DFW＞1 or TAW/FAW＜1 indicates a poor reduction of the fracture and predicts poor postoperative recovery of knee joint function.

OBJECTIVE: To investigate early effectiveness of arthroscopic superior fulcrum reconstruction in the treatment of irreparable massive rotator cuff tear (IMRCT). METHODS: A retrospective analysis was conducted on the clinical data of 24 patients with IMRCT who met the inclusion criteria between January 2020 and April 2022. Among them, there were 11 males and 13 females with an average age of 56.2 years (range, 42-68 years). There were 12 cases of falling injuries, 3 cases of traction injuries, and the other 9 cases had no obvious causes. The disease duration ranged from 1 to 25 months (median, 6 months). The rotator cuff tears were classified as Hamada grade 2 in 18 cases and grade 3 in 6 cases, and Goutallier grade 1 in 3 cases, grade 2 in 20 cases, and grade 3 in 1 case. All patients were treated with arthroscopic superior fulcrum reconstruction. Visual analogue scale (VAS) score, Constant-Murley score, the University of California at Los Angeles (UCLA) score, and the American Shoulder and Elbow Surgeons (ASES) score were recorded before operation and at 1, 3, 6, and 12 months after operation. RESULTS: The operations were all successfully completed. The incisions healed by first intention and no related complications occurred. All patients were followed up 12-33 months (mean, 24.6 months). The VAS, Constant-Murley, UCLA, and ASES scores at different time points after operation were superior to those before operation ( P<0.05). All of the above indicators further improved with time. Except for no significant difference in VAS and Constant-Murley scores between 6 and 12 months ( P>0.05), the differences between the other time points were significant ( P<0.05). At 12 months after operation, according to UCLA scoring standard, shoulder joint function was rated as excellent in 4 cases, good in 19 cases, and poor in 1 case, with an excellent and good rate of 96.0%. MRI showed that there was no graft re-tear and the transplanted tendon and bone tunnel healed. CONCLUSION The arthroscopic superior fulcrum reconstruction for IMRCT can effectively relieve the pain, improve the shoulder range of motion, and restore good shoulder function.

OBJECTIVE To understand the safety of Ilaprazole sodium for injection in clinical practice. METHODS From Jan. 1st 2019 to Feb. 29th 2020， the data of 3 926 valid hospitalized patients receiving Ilaprazole sodium for injection were collected prospectively from 5 third-level hospitals through CHPS， and the post-marketing safety analysis was performed by using retrospective multicenter single cohort study. At the same time， a nested case-control study （the ratio of trial group and control group was 1∶4） was used to confirm the baseline stability of this study cohort and the correlation between adverse reactions and Ilaprazole sodium for injection. RESULTS Among 3 926 patients， 3 patients experienced 5 adverse drug events after using Ilaprazole sodium for injection， with the incidence of 0.076%. There was no serious adverse event， and the occurrence time was 2 days after medication； adverse drug events mainly include elevated liver function indicators （alanine transaminase， aspartate transaminase， total bilirubin）， which were mild and untreated， and all adverse drug events were improved. The results of the nested case-control study showed that the trial group and the control group belonged to the same background baseline， and the occurrence of adverse drug events was more closely related to Ilaprazole sodium for injection. CONCLUSIONS The overall safety of Ilaprazole sodium for injection is relatively high， and the occurrence of adverse events is more related to it.
