Corticosteroids in Carpal Tunnel Syndrome. Prospective Randomised Controlled Non-inferiority Study
Systemic Versus Local Corticosteroids in the Treatment of Carpal Tunnel Syndrome. Prospective Randomised Controlled Non-inferiority Study.
The goal of this prospective, randomised, controlled, non-inferiority analytical study is to compare the Boston score in patients treated with systemic (intramuscular) versus local infiltration corticosteroids in mild and moderate carpal tunnel syndrome in patients over 18 years of age with mild or moderate carpal tunnel syndrome.
The main questions it aims to answer are:
- What is the effectiveness of intramuscular injection of corticosteroids compared to local infiltration in the treatment of mild/moderate carpal tunnel syndrome?
- What are the adverse effects and application site pain associated with each route of administration?
Patients who meet the inclusion criteria will be asked to participate in the study and sign an informed consent form.
The Redcap randomizer will be used to assign the patient to one of the branches.
Researchers will compare
- Branch A: patients treated with local corticosteroid infiltration in carpal tunnel under ultrasound
- Branch B: patients treated with intramuscular corticosteroid injection.
Researchers will:
- Compare Boston Carpal Tunnel Questionnaire score at 1.5 months, 3 months, 6 months and 12 months post-procedure.
- Describe adverse reactions associated with the route of administration.
- Compare the pain at the site of application associated with the route of administration.

Detailed Description
Carpal tunnel syndrome (CTS) is the most common peripheral compressive neuropathy of the upper limb, consisting of involvement of the median nerve at the level of the carpal tunnel. It has a prevalence of 7% to 16% in the United Kingdom adult population, while in the United States between 400/500 thousand patients are treated surgically, with an annual economic cost exceeding $2 billion.
A variety of treatments are available according to the stage of the pathology, including splinting, kinesic therapy, ultrasound, non-steroidal anti-inflammatory drugs, systemic or local corticosteroids , as well as surgical treatment in patients who do not respond to previous options.
Corticosteroid infiltration is one of the most widely used methods for the treatment of idiopathic carpal tunnel syndrome (ICTS) in mild and moderate stages, and short-term symptomatic improvement is reported in the literature, although the optimal dose and drug used for the same is varied in the various published studies, and is still a matter of debate in the literature. Betamethasone has greater anti-inflammatory power and a longer duration of action at the same equivalent dose than other corticosteroids used in the treatment of CTS (prednisolone, methylprednisolone, triamcinolone, cortisone).
In addition, ultrasound-guided local infiltration helps prevent iatrogenic injury compared to anatomical repair-guided infiltration. Studies show improvement in scores assessing symptomatology, although there is no strength in determining improvement in functional and electromyographic assessment. The rate of adverse reactions with this technique is low, reported to be <0.1% for major complications, and 2% for minor complications.
The effectiveness of local and systemic corticosteroids has been demonstrated, but whether there is any difference in clinical improvement in patients between one route of administration versus the other remains a question mark.
Rationale for the study In the institution, both intramuscular and ultrasound-guided administration of systemic corticosteroids are part of standard practice, with systemic administration indicated in the trauma department and ultrasound-guided administration in the rheumatology department. Although, given that these are standard practices, retrospective evaluation of the cases could answer the objective of this study, in the review of the cases the investigators found an imbalance in the type of CTS in the cohorts treated in each department. This is mainly due to the fact that in the orthopaedics service most patients consult for CTS and in the rheumatology service, due to the speciality itself, there is a large proportion of patients with secondary CTS (rheumatoid arthritis, juvenile arthritis, gout, etc.). Because of this, and to avoid patient selection bias, the aim of this study was to compare the efficacy of systemic (intramuscular) corticosteroid treatment with local infiltration in ICTS.
The same efficacy of systemic administration (intramuscular) as local administration (via ultrasound-guided infiltration in the carpal tunnel) should reduce the cost of treatment and the complications associated with local injection. In addition, it would allow effective treatment in centres where there are no specialists trained in the ultrasound-guided infiltration technique, allowing greater generalization of the treatment.
The investigator's hypothesis is that intramuscular corticosteroid infiltration (systemic effect) offers the same results in terms of symptom improvement as locally applied corticosteroids under ultrasound.
The primary objective is to compare the Boston score in patients treated with systemic (intramuscular) versus local infiltration corticosteroids in mild and moderate ICTS at 1.5 months, 3 months, 6 months and 12 months post-procedure.
The exploratory objectives are to describe adverse reactions associated with the route of administration and to compare the pain at the site of application associated with both methods, in relation to the technique used, measured with the Visual Analogue Pain Scale (VAS).
