Research Objectives
To investigate the effectiveness of thread carpal tunnel release (TCTR) with newly
developed thread (Ultra V sswire™, 0.45mm in diameter, Korea) in clinical settings.
Design
Observational cohort study (During 42-month period).
Setting
Outpatient rehabilitation clinic and University medical center.
Participants
Patients diagnosed with carpal tunnel syndrome (N=12).
Interventions
Thread carpal tunnel release was standardized by keeping the entry point at the middle
of the palm, exit point at just the medial to the palmaris longus tendon. Modified
thread carpal tunnel release, an ultrasound-guided minimally invasive technique which
accomplishes transection of transverse carpal ligament using needle and thread, was
performed to each patient.
Main Outcome Measures
The Numeral Rating Scale and Boston Carpal Tunnel Syndrome Questionnaire were used
to assess the monthly outcomes after the procedure, for 3 months.
Results
The average age of patients was 53.6±13.3 (31 to 73 years). There were 9 females and
3 males. The diagnosis of carpal tunnel syndrome was based on standard clinical criteria
including electromyography, resulting 8 wrists as severe degree, 6 wrists as moderate
degree by the AANEM classification. Fourteen wrists were analyzed. Thread carpal tunnel
release procedure with our newly developed thread had significantly improved all variables,
showing its effectiveness in both pain and patient's functional ability. Numeral Rating
Scale and Boston Carpal Tunnel Syndrome Questionnaire severity and the functional
scale showed a significant decrease at the initial stage and progressive improvement
during each monthly follow-up of our study until last 3 months' period.
Conclusions
Thread carpal tunnel release applying our newly developed thread is effective in pain
relief and increasing functional activity, lasting for more than 3 months. Future
studies with more samples are needed to further support the results.
