Clinical Trial Summary
This study aims to investigate whether intra-articular corticosteroid injection, followed by
hypertonic dextrose injection and shoulder joint capsular distension, is more effective than
saline injection and shoulder joint capsular distension for treating frozen shoulder.
Description:
Frozen shoulder (FS), also known as adhesive capsulitis, is a prevalent shoulder condition,
with an annual incidence of around 2.4 individuals per 100,000, representing approximately 2%
of the total population. Symptoms typically manifest in individuals aged forty to sixty
years, characterized by persistent limitations in shoulder joint mobility accompanied by
pain.
While the specific mechanisms driving frozen shoulder remain unclear, arthroscopic
examination of the shoulder joint reveals thickening and contraction of the shoulder joint
capsule, adhesion with the humeral head, and a reduction in joint cavity volume, particularly
in the folds of the axillary recess of the joint capsule and its surrounding areas. These
changes contribute to restricted shoulder joint mobility. Additionally, research suggests
that severe inflammation may lead certain cytokines and growth factors to drive fibroblasts
to replace normal tissue through repair and remodeling responses. This excessive fibrosis,
along with the loss of a normal collagen remodeling response, further contributes to the
development of frozen shoulder.
The 2020 meta-analysis published in JAMA Network underscored the importance of medium to
long-term physical therapy in enhancing subsequent improvements in range of motion and
functionality for patients with adhesive capsulitis or frozen shoulder. Furthermore, numerous
studies indicate that combining intra-articular injections with shoulder joint capsular
distension procedures, such as hydrodilatation, can enhance shoulder joint function and
mobility.
Prolotherapy, a non-surgical regenerative injection therapy, involves injecting a solution
into painful or degenerated areas. The injected proliferants induce a local inflammatory
response, triggering the release of growth factors and stimulating fibroblasts and
collagen-producing cells. This process mimics the natural healing mechanisms of the body,
promoting cellular tissue growth through a beneficial inflammatory response. In clinical
practice, the most commonly utilized solution for prolotherapy is hypertonic dextrose, with
concentrations ranging from 15% to 25%. Concentrations exceeding 10% are generally considered
to induce local inflammation, thereby initiating a cascade of reparative effects.
Although numerous studies have investigated shoulder joint capsular distension procedures in
the past, the injected solutions often comprised corticosteroids and saline. In clinical
observations, the use of hypertonic dextrose injection combined with shoulder joint capsular
distension appears to yield improved outcomes in terms of pain relief and joint angle
progression in patients with adhesive capsulitis. However, there is currently no research
investigating the effectiveness of hypertonic dextrose injection combined with shoulder joint
capsular distension for treating frozen shoulder. This study aims to explore whether
intra-articular corticosteroid injection, followed by hypertonic dextrose injection and
shoulder joint capsular distension, is more effective than saline injection and shoulder
joint capsular distension for treating frozen shoulder.
