Brief summary: The aim of this study is to assess the effectiveness of therapeutic modalities (paraffin, ultrasound and orthotics) versus corticosteroid injection for trigger finger.

Detailed description: There are several forms of nonsurgical treatment for trigger finger, the most used are:

* Oral nonsteroidal and steroidal antiinflammatory's drugs use to resolve the inflammatory process
* Corticosteroids local injection: that proposes to control the inflammation, these injections have shown good effectiveness for trigger finger treatment.
* Orthotic: with the aim of to immobilize the affected joint until the resolution of the inflammatory process.
* Electrotherapeutic modalities:
* Paraffin that increases cellular metabolism and promotes peripheral vasodilatation, favoring the transduction tissue fluid, lymph flow, hyperemia and consequent absorption of exsudato.
* LASER -Lower Level Laser Therapy (LLLT): the absorption of light through the skin's photoreceptors stimulates mitochondrial chain reactions, promoting adenosine triphosphate (ATP) synthesis, acting on gene expression, which raises the level of growth factors and Tissue repair

Although the non-surgical treatment is often used there is no evidence in the literature of which is the most effective conservative treatment for trigger finger. Thus, it is necessary use appropriate methodology to define the benefits and harms of each treatment modality and assess the effectiveness of these nonsurgical treatments, and may define which one has a higher resolution and lower rates of trigger finger recurrences in short, medium and long term.

Eligibility criteria: Inclusion Criteria:

* 2-3 grade of trigger finger (Quinnell´s classification)
* Signing the Terms of Consent.

Exclusion Criteria:

* Presence of finger trigger in children
* Presence of traumatic finger trigger
* Secondary causes (patients with tumor of the tendon sheath,

synovitis tuberculosis, etc ...)
