Open vs. Ultrasound-Guided Carpal Tunnel Release
Prospective Multicenter Trial Comparing Open Surgical Decompression Versus Minimally Invasive Ultrasound-Guided Carpal Tunnel Release

Detaillierte Beschreibung
Carpal Tunnel Syndrome (CTS) is the most common compression neuropathy of the median nerve. Open Surgical Carpal Tunnel Release (OSCTR) has been established as the clinical gold standard. However, the procedure is associated with a palmar incision and may result in scar pain, including pillar pain, and delayed return to manual activities.
Ultrasound-Guided Carpal Tunnel Release (USGCTR) is a minimally invasive technique that permits division of the flexor retinaculum under continuous sonographic visualization through a minimal incision at the distal forearm or wrist crease. Potential advantages include avoidance of a painful scar in the load-bearing area of the hand and potentially faster recovery.
The study aims to compare functional recovery and symptom relief following OSCTR versus USGCTR. Secondary objectives include comparison of postoperative pain, subjective outcome, return to work, patient satisfaction, and complication rates.
This is a prospective, multicenter observational cohort study. Patients are not randomized. Assignment to the two cohorts is determined by the participating treatment center and its respective standard procedure. Patients choose the treatment center based on referral by their previously treating neurologist or on personal information. The study team does not influence this decision. Both procedures are established standard procedures routinely performed at the respective institutions.

Open Surgical Carpal Tunnel Release (OSCTR)
Patients undergoing open surgical decompression at AUVA Unfallkrankenhaus Salzburg as the standard procedure of the participating center.
|
Open surgical decompression of the carpal tunnel (OSCTR) is performed at UKH Salzburg as the established standard surgical treatment for carpal tunnel syndrome.
The procedure involves open surgical release of the flexor retinaculum.
Intraoperative findings and immediate complications are documented.

Ultrasound-Guided Carpal Tunnel Release (USGCTR)
Patients undergoing minimally invasive ultrasound-guided carpal tunnel release at the University Institute of Radiology, Paracelsus Medical Private University Salzburg, as the standard procedure of the participating center.
|
Ultrasound-guided carpal tunnel release (USGCTR) is performed at the University Institute of Radiology of the Paracelsus Medical Private University.
The minimally invasive procedure involves release of the flexor retinaculum under continuous sonographic visualization through a minimal incision at the distal forearm or wrist crease.
Intraoperative findings and immediate complications are documented.
