Abstract：Objective To observe the clinical efficacy of ultrasound-guided multi-point injection of platelet-rich plasma(PRP)in the treatment of primary frozen shoulder.Methods A total of 64 patients with primary frozen shoulder who met the inclusion criteria from January 2019 to December 2021 were selected,and the patients were divided into PRP treatment group and non-PRP treatment group,with 32 patients in each,according to the patients'wishes and daily life needs.Patients in PRP treatment group received ultrasound-guided injection of PRP into the subacromial bursa,coraco-humeral ligament and shoulder joint cavity;patients in non-PRP treatment group were only given symptomatic and sup-portive treatment.The shoulder function was evaluated by visual analogue scale(VAS),Constant-murley score and range of motion(ROM)before and after treatment.Results There was no significant difference in VAS score of shoulder joint between the two groups before treatment(P＞0.05).The VAS score of PRP treatment group were lower than those of non-PRP treatment group at each timing(1 week,6 weeks and 3 months)after treatment,and the differences between the two groups were statistically significant(all P＜0.05).In addition,the shoulder joint VAS score of the two groups after treatment had a significant downward trend,which were significantly lower than those before treatment(all P＜0.05).There was no significant difference in Constant-murly score and the forward flexion,abduction and external rota-tion angles of shoulder joint between the two groups before treatment(P＞0.05),the Constant-murly score and forward flexion,abduction and external rotation angles of shoulder joint in PRP treatment group were higher than those in non-PRP treatment group at each timing(1 week,6 weeks and 3 months)after treatment(all P＜0.05).Constant-murly score and the forward flexion,abduction and external rotation angles of shoulder joint in the two groups showed a significant upward trend,and were significantly higher than those before treatment(all P＜0.05).Conclusion Ultrasound-guided PRP multi-point injection can effectively reduce the pain of patients with frozen shoulder and improve the function of shoulder joint.
