NCT05435950

Brief Summary

Carpal Tunnel (CT) syndrome is a collection of characteristic symptoms and signs that occurs following compression of the median nerve within the CT. In Trigger Finger / trigger thumb (TF), one of the most common causes of hand pain and disability, the flexor tendon causes painful popping or snapping as the patient flexes and extends the digit. In case of failure of non-operative treatments, patients with CT syndrome or TF are operated. Clearly any improvement in surgical device design would be of great advantage to the patient and the surgeon. Spirecut's single use, pre-CE Sono-Instruments (SI) allow the percutaneous treatment of Carpal Tunnel (CT)syndrome and Trigger Finger/thumb (TF) under sonography (instead of open or endoscopic approach). Two models will be assessed in this clinical investigation:

  1. 1.The Carpal Tunnel Sono-Instrument® (CT-SI), for CT syndrome release, by progressively cutting the transverse carpal ligament.
  2. 2.The Trigger Finger Sono-Instrument® (TF-SI), for TF release by progressively cutting the A1 annual pulley.

Spirecut's single use, pre-CE Sono-Instruments (SI) allow the percutaneous treatment of Carpal Tunnel (CT) syndrome and Trigger Finger/thumb (TF) under sonography (instead of open or endoscopic approach). Two models will be assessed: * The Carpal Tunnel Sono-Instrument® (CT-SI), for CT syndrome release, by progressively cutting the transverse carpal ligament. * The Trigger Finger Sono-Instrument® (TF-SI), for TF release by progressively cutting the A1 annual pulley.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adults ≥ 18 years of age;
  • Primary CT confirmed by typical symptoms, signs and altered nerve conduction studies;
  • Pain and/or numbness in the hand which worsen at night (or are present only at night);
  • Participant and investigator signed and dated the Informed Consent Form (ICF) prior to the index-procedure.
  • Participants with Trigger Finger/thumb:
  • Adults ≥ 18 years of age;
  • Typical signs and symptoms of TF/thumb caused by friction or blockade of flexor tendon(s) in digital sheath, without flexion contracture over 30° of the proximal interphalangeal (or interphalangeal for the thumb) joint, confirmed by altered flexor tendon(s) gliding and/or increased thickness of A1 digital pulley under sonography (sonography can be done just before the operation, that is after signature of the ICF);
  • Participant and investigator signed and dated the ICF prior to the index-procedure.

You may not qualify if:

  • Participants with one or more of the following conditions are excluded from the study:
  • Dwarfism or participants with small size hand/CT/TF-thumb;
  • Past or active infection;
  • Known allergic reaction to metals;
  • Coagulation problems, with significant risk of per/postoperative bleeding;
  • In case of TF: long evolution, with ankylosis of the proximal interphalangeal joint;
  • In case of CT: severe median nerve dysfunction;
  • Previous facture or dislocation in the operated area or any affection causing malalignment or distortion of the local skeleton due to trauma, arthritis or other causes;
  • Other known clinical risks outweighing the expected clinical benefits or increasing the risk of a postoperative lesion (e.g. tissue adhesions, anatomical abnormalities, neuro-vascular structures in the zone of the intended release, local tumors);
  • Insufficient sonographic identification of the operated tissue;
  • Previous attempt to treat the condition;
  • Currently receiving treatment for CT or TF;
  • Contra-indication to local anesthesia (general, regional or local);
  • Participant unable (vulnerable participant)/unwilling to provide informed consent;
  • Participant is enrolled in another study.
