Objective To investigate the efficacy of acupuncture combined with ozone local injection in the treatment of stenosing tenosynovitis of radial styloid process.Methods A total of 86 patients with stenosing tenosynovitis of radial styloid process who were admitted to Affiliated Sport Hospital of Chengdu Sport University from September 2020 to September 2021 were enrolled in this prospective study.They were randomly divided into observation group(n=43)and control group(n=43)with the method of random sampling.The control group was treated with acupuncture,and the observation group was treated with acupuncture and ozone local injection.After 2 weeks of treatment,the clinical efficacy and adverse reactions were compared between the two groups.The traditional Chinese medicine(TCM)symptom score,Cooney wrist score and inflammatory reaction were recorded before and after treatment.Results The total effective rate of the observation group was higher than that of the control group(P<0.05).The scores of local swelling,tenderness and TCM symptoms of fist-clenching and ulnar deviation,and the levels of C-reactive protein(CRP),interleukin 6(IL-6)and tumor necrosis factor α(TNF-α)were decreased after treatment in both groups,and these indexes in the observation group were significantly lower than those in the control group(P<0.05).After treatment,the scores of wrist joint function,range of motion and grip strength were increased after treatment in both groups,and the scores in the observation group were significantly higher than those in the control group(P<0.05).There was no significant difference in the total incidence of adverse reactions between the two groups(P>0.05).Conclusion Acupuncture combined with ozone local injection can achieve good outcomes in the treatment of stenosing tenosynovitis of radial styloid process.The curative effect of acupuncture combined with ozone local injection is superior to ozone local injection alone.

Objective: To investigate the clinical efficacy of tight suturing for shortening healing scar tissues in repair of Myerson type III old rupture of Achilles tendon. Methods: A retrospective case series study was performed to analyze the clinical data of 16 patients with Myerson III type chronic Achilles tendon ruptures admitted to Sports Hospital Affiliated to Chengdu Sport University from January 2015 to December 2017. All of the patients were males with sports injuries, aged 19-71 years (mean, 40.6 years). The Achilles tendon defect was 5-7 centimeter (mean, 5.2 centimeter). The patients received tight suturing and shortening healing scar tissue for the repair. The operation time and surgical wound size were recorded. The clinical efficacy was evaluated by Amer-Lindholm standard and American 0rthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score. Meanwhile, the complications such as wound infection, Achilles tendon re-rupture, heel lifting weakness, muscle strength decline, ankle dysfunction, lameness and symptoms of sural nerve injury were recorded. Results: All patients were followed up for 11-41 months, with an average of 26 months. The operation time ranged from 25-51 minutes, with an average of 37 minutes. The incision was 4-12 cm, averaging 7 cm. According to the Amer-Lindholm standard, 14 patients were graded as excellent and two were graded as good, with the excellent and good rate of 100%. AOFAS ankle-hindfoot score increased from (42.7±6.8)points before operation to (95.1±4.9)points at the last follow-up (P<0.05). During the follow-up, there were no complications such as infection, Achilles tendon rupture, heel lifting weakness, muscle strength decline, ankle joint dysfunction, lameness and gastrocnemial nerve injury. Conclusion For Myerson type III old rupture of Achilles tendon, tight suturing for shortening healing scar tissue can increase the postoperative function scores without wound infection or complications.
