To explore the clinical efficacy of ultrasound-guided peri-shoulder injection of anti-inflammatory analgesic solution and external application of musk chase analgesic paste in the treatment of shoulder periarthritis.

Between January 2020 and December 2020, 86 patients with periarthritis in The Department of Pain Clinic, The First Affiliated Hospital of Xinxiang Medical College, were enrolled and divided into combined treatment group and oral drug group, 43 cases in each group. The patients were treated by ultrasound-guided peri-shoulders injection of anti-inflammatory analgesic solution and topical musk chase analgesic paste in the combined treatment group. The anti-inflammatory analgesic fluid was prepared as 2% lidocaine 5 ml+ triamcinolone acetonide 10 mg, with 0.9% normal saline diluted to 20 ml, and injected once a week, a total of 3 times; the next day after each injection, musk chase analgesic paste was applied topically, 1 paste a day, a total of 10 paste. The patients in the oral medication group were treated with meloxicam 7.5 mg orally, once a day; tizanidine tablet 1 mg orally, 3 times a day, for 2 weeks. The numerical rating scale (NRS), Pittsburgh sleep quality index (PSQI) and range of shoulder motion were compared in the two groups before the treatment and 1 month after the treatment.

There were no significant differences in gender, age, course of disease and NRS before the treatment between the two groups (all P>0.05). One month after the treatment, the NRS and PSQI were lower in both groups than those before the treatment (all P<0.05). NRS and PSQI were lower and the shoulder joint function improved better in the combined treatment group than those in the oral medication group (all P<0.05). The total effective rate was higher in the combined treatment group than that in the oral medication group (P<0.05).

Ultrasound-guided peri-shoulder injection of anti-inflammatory analgesic solution combined with topical musk chase analgesic paste can effectively relieve pain, improve sleep quality and improve the function of shoulder joint, which is better than oral medication treatment.
