Abstract:
Objective:To investigate the effects of musculoskeletal ultrasound(MSUS)-guided shoulder joint capsule hydraulic expansion method combined with rotator interval(RI)injection method on ultrasound imaging indicators,shoulder function,and serum inflammatory factors in treating patients with early primary frozen shoulder(PFS).Methods:A total of 168 patients with early PFS admitted to Jiangbei District of The Frist Affiliated Hospital to Army Medical University between June 2021 and June 2023 were selected.They were randomly divided into a control group and an observation group by using a random number table,with 84 patients in each group.The control group received the therapy with MSUS-guided shoulder joint capsule hydraulic expansion.The observation group received the therapy with RI injection on the basis of the control group.After 5 weeks of treatment,the changes of the following parameters were compared and analyzed between the two groups:Visual Analog Scale(VAS)score for shoulder pain,Simple Shoulder Test(SST)score,Constant-Murley Score(CMS),thickness of the glenohumeral joint capsule at the axilla of ultrasound imaging,thickness of coracohumeral ligament(CHL),RI thickness,positivity rate of RI blood flow,passive range of motion(ROM)of the shoulder joint,and serum inflammatory factor levels including tumor necrosis factor-α(TNF-α),C-reactive protein(CRP)and interleukin-6(IL-6).Results:At 5th week after treatment,both groups showed VAS scores decreased,and SST and CMS scores increased.The VAS score(1.34±0.30)of observation group was significantly lower than(1.97±0.46)of control group,and the SST score and CMS score were significantly higher than those of control group(t=10.514,9.597,7.910,P<0.05),respectively.Both groups showed decreases in thickness of the glenohumeral joint capsule at the axilla,CHL thickness,RI thickness,and positivity rate of RI blood flow,and these indicators of observation group were significantly lower than them of control group,with statistically significant differences(t=5.518,16.106,9.050,25.211,P<0.05).The ranges of backward extension and outward rotation of observation group were larger than those of control group,and the differences were statistically significant(t=9.209,12.447,P<0.05).The serum levels of TNF-α,IL-6 and CRP of observation group were significantly lower than those of control group,and the differences were statistically significant(t=10.523,17.750,19.995,P<0.05),respectively.Conclusion:The treatment of MSUS-guided shoulder joint capsule hydraulic expansion combined with RI injection can effectively alleviate the degrees of shoulder pain and dysfunction in patients with early PFS,and improve indicators of ultrasound imaging,the ROM values of outward rotation and backward extension,and reduce serum levels of inflammatory factors,which have favorable therapeutic effects.
