Introduction: Frozen shoulder is common and disabling. While the natural history indicates improvement over time, many patients experience enduring limitations. Hydrodistension has been previously shown to improve pain and range of motion in the short and medium term, but longer-term outcome data is lacking.
Aim: The current study aims to assess the longer-term efficacy of hydrodistension for frozen shoulder.
Methods: 67 patients who had failed noninvasive management of frozen shoulder were treated with hydrodistension and reviewed at 23.93±16.32 months (range 58.5 –2 months). Cohort mean age was 52.25±7.03. 35/67 were female. Data included Constant, QuickDASH and VAS satisfaction scores both pre- and post-procedure.
Results: Patient satisfaction improved from 1.69±1.81 to 9.30±1.48 (p<0.0001). Quick DASH improved from 44.23±22.45 to 6.85±9.54 (p<0.0001). Constant scores increased from 23.86±12.81 to 84.18±15.27 (p<0.0001).
Discussion: Hydrodistension achieves high efficacy and satisfaction score and it maintains a strongly positive treatment effect at two years in frozen shoulder. Hydrodistension should be considered as a first line treatment in the invasive management of frozen shoulder.
