A Double-blinded Randomized Controlled Multicenter Trial Comparing Proximal ROw carpectOmy and Four-corner Fusion (PROOF) for Osteoarthritis of the Wrist

Study purpose is to compare the outcome after proximal row carpectomy (PRC) vs four-corner fusion (FCA) for SLAC/SNAC II-III type osteoarthritis (OA) in a double-blinded randomized controlled study setting.

Patients with radiologically and clinically confirmed OA are randomized (1:1 computer generated sequence with random block size) to two parallel groups and will undergo either PRC or FCA. The study will be patient and assessor blinded.

Baseline data is collected preoperatively and is followed by a follow-up visits at 2 and 6 weeks, 3, 6, 12 months, and 5, 10 years after the intervention. Unveiling of the allocation is at 12 months post-intervention.

Inclusion: SLAC/SNAC II-III; Age 18 - 75; Symptom duration > 3 months; American Society of Anaesthesiologists physical status (ASA) I-II.

Exclusion: Alcohol or drug abuse; Condition or medication affecting bony healing (eg diabetes mellitus with poor glycemic control, malnutrition, use of per oral corticosteroids); Neurological condition affecting upper limb function; Age <18 or >75 years; Patient eligible for SL reconstruction or scaphoid; Ulnocarpal/pancarpal arthritis; Lunate fossa, proximal lunate arthrosis or both; Rheumatoid arthritis; Heavy smoking (> 20 cigarettes per day).
