Brief Summary
A multi-center randomized controlled clinical trial which determines the efficacy of proximal median nerve release in patients with persistent proximal median nerve compression. The primary outcome is patient reported improvement of symptoms on a 7-point Likert scale at 6 months after the randomization to treatment group.

Study Arms (2)
Proximal median nerve release
EXPERIMENTALOperative treatment: proximal median nerve release
Physiotherapy
ACTIVE COMPARATORConservative treatment: physiotherapy
Interventions
Participants randomized to operative treatment will be scheduled for surgery. During surgery, the proximal median nerve compression will be released in a manner deemed best by the treating surgeon. Patients randomized to surgery will also receive conservative management following surgery.
Participants randomized to conservative treatment will receive information about median nerve compression and written instructions for self-directed nerve stretching exercises. There will be one supervision visit with a physiotherapist at the beginning of the treatment period.
Eligibility Criteria
You may qualify if:
- Clinically diagnosed PMNC
- If the patient has clinically and electrodiagnostically confirmed carpal tunnel syndrome, at least 6 months must have passed since surgical treatment
- Age 18 or over
- Ability to understand Finnish
- Ability to complete electronic questionnaires independently
- Willingness to participate in research and follow research instructions
- Provision of informed consent from the participant
You may not qualify if:
- Nerve root disorder findings in ENMG
- Thoracic outlet syndrome, TOS
- Other neurological condition that causes upper limb symptoms such as MS, previous nerve injury
- Active rheumatoid arthritis or any other active inflammatory joint disease that affects hand function
- Significant compression symptoms of another peripheral nerve in association with PMNC
- Other upper extremity operation performed less than 6 months ago
- Another disease or condition that accounts for most of the patient's symptoms
- Other known reasons that may prevent participation or implementation of treatment during the study
