Trigger finger is a common pathology in the hand. Patients suffer from pain and depending on which tasks, patients have difficulty to perform them. Its treatment in initial and less serious phases includes conservative measures, but failure of these may require releasing the trigger finger with surgery. The surgical technique performed for trigger finger is the opening of the A1 pulley, the skin incisions used for this surgery are various (transverse, longitudinal, oblique). Trigger finger surgery presents good results in terms of resolution, but complications may also occur. The reason for this study is to assess whether there are functional differences using the Dash scale when we perform a transverse or longitudinal incision in trigger finger surgery.

Inclusion Criteria:

• Patients over 18 years of age.
• Clinical diagnosis of trigger finger grade II to IV.

Grade I (pre-trigger) Pain, history of entrapment, but not demonstrable on physical examination, tenderness over the A1 pulley.

Grade II (active) Demonstrable entrapment, but the patient can actively extend the finger.

Grade III (passive) Demonstrable entrapment, patient requires passive extension IIIA or inability to actively flex IIIB.

Grade IV (contracture) Demonstrable entrapment with fixed flexion contracture of the PIP.

Exclusion Criteria:

• Thumb
• Polydigital
• Allergy to local anesthetics and/or vasoconstrictor agents.
• Previous surgery
• Patients who, in the researcher's opinion, are not good candidates for the study (e.g. inability to comply with the follow-up program, comorbidity, poor physical or mental health in general, drug or alcohol abuse problems...).
