Needle fasciotomy versus limited fasciectomy for the treatment of Dupuytren’s contractures of the fingers (Hand-2): study protocol for a randomised controlled trial

Background: Dupuytren’s contractures (DC) are fibrous cords under the skin of the hand that cause one or more fingers to curl gradually and irreversibly towards the palm. These contractures are usually painless but can cause a loss of hand function. Two treatments for Dupuytren’s contractures are widely used within the National Health Service (NHS) in the United Kingdom: removal of the contractures via surgery (limited fasciectomy), and division of the contractures via a needle inserted through the skin (needle fasciotomy).
This study aims to establish the clinical and cost effectiveness of needle fasciotomy (NF) versus limited fasciectomy (LF) for treatment of DC in the NHS, in terms of patient reported hand function and resource utilisation.
Methods/design: Hand-2 is a national multi-centre, two-arm, parallel group randomised, non-inferiority trial. Patients will be eligible to join the trial if they are aged 18 years or older, have at least one previously untreated finger with a well-defined Dupuytren’s contracture of 30 degrees or greater that causes functional problems and is suitable for treatment with either LF or NF. Patients with a contracture of the distal interphalangeal joint only are ineligible. Eligible consenting patients will be randomised 1:1 to receive either NF or LF and will be followed up for 24 months post treatment. A QuinteT Recruitment Intervention will be used to optimise recruitment. The primary outcome measure is the participant reported assessment of hand function, assessed by the Hand Health Profile of the Patient Evaluation Measure (PEM) questionnaire at 12 months post treatment. Secondary outcomes include other patient reported measures, loss of finger movement, and cost-effectiveness, reported over the 24 months post treatment. Embedded qualitative research will explore patient experiences and acceptability of treatment at 2 years post-surgery. Discussion: This study will determine whether treatment with needle fasciotomy is non-inferior to limited fasciectomy in terms of patient-reported hand function at 12 months post-treatment.
