Background:
The incidence of adhesive capsulitis varies from 2-5% in the general population to 20% in people with diabetes. One of the most effective treatment methods is hydrodilatation, which can be done under US-guidance or Fluoroscopic guidance. However, the clinical effectiveness of US-guided injections in comparison to fluoroscopy-guided injections is still debatable. The possibility of severe side effects, the expense, and the time required to carry out this minimally invasive procedure highlight how crucial it is for patients to have a precise intra-articular injection. This study aims to compare the effectiveness of Ultrasound-guided vs. Fluoroscopic guided hydrodilatation for patients with adhesive capsulitis.
Methods:
Sixty-four patients were randomly selected for hydrodilatation using any one of the techniques. The patients were evaluated for clinical improvements using the visual analog scale (VAS), oxford shoulder score (OSS), and range of motion (ROM).
Results:
The US-guided group experienced more pain reduction than the fluoroscopy group within the first four weeks (P < 0.001). The increase in ROM was much more significant in the US-guided group for the first 8 weeks. Improvement in Abduction and External rotation was much more significant (P < 0.001) in the first 4 weeks after hydrodilatation in the US-guided group. The improvement in ROM was maintained on long-term follow-up (mean 24 months), with 45 out of 64 (70.3%) reporting a normal or near normal ROM. On assessing the Oxford shoulder score improvements, the US-guided group's score significantly increased after the first week (P = 0.003), but the fluoroscopy-guided group's score increased after the second week. On comparison between the two groups, the amount of score improvement was more significant in the US-guided group than in the fluoroscopy-guided group in the first 4 weeks (P < 0.001).
Conclusion:
US-guided technique for intra-articular injection for patients with adhesive capsulitis provided a quicker pain reduction and a larger improvement in range of motion and overall shoulder functions.
