Not Applicable
Recruiting
Conditions
Wrist Osteoarthritis
Scapholunate Advanced Collapse
Interventions
Procedure: Four-corner fusion
Procedure: Proximal Row Carpectomy
Registration Number
NCT04260165
Lead Sponsor
Töölö Hospital
Brief Summary

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.

Primary Outcome Measures
NameTimeMethod
Patient-Rated Wrist Evaluation12 months

The PRWE comprises 15 questions to measure wrist pain and disability in daily activities. In PRWE patients rate wrist pain and disability from 0 to 10 and it consists two subscales: Pain and Function (0=best possible outcome, 10=worst possible outcome)

Secondary Outcome Measures
NameTimeMethod
Quick-Disabilities of the Arm, Shoulder and Hand12 months

The QuickDASH is self-reported questionnaire and shortened version of DASH outcome measure to measure physical function and symptoms in people with any or multiple musculoskeletal disorders of the upper limb in 11 dimensions in 1-5 scale (1=best possible outcome, 5=worst possible outcome)

Pain (Visual Analogue Scale)12 months

The VAS is derived by health care professional question of pain in scale 0 to 10 (0=no pain, 10=worst possible pain)

Patient-rated Quality of Life (EQ-5D)12 months
Global improvement12 months

Global rating to treatment effect will be evaluated by question: "How would you rate the function of your hand compared to the situation before the treatment?". The options are in 5-step Likert scale from (-2) Much worse to (+2) Much better

Grip strength12 months

Grip strength is measured with a dynamometer in kg as the mean of three measurements. It will be numbered in kg and percentage of the unaffected side

Wrist range of motion (ROM)12 months

Wrist ROM is measured on both wrists with a handheld goniometer in degrees.

Cost-effectiveness12 months

Quality-adjusted life years/months measured as a change in EQ-5D

Complications12 months

Incidence of complications (i.e. non-union, fracture, reoperation, infection, hematoma, iatrogenic tendon/nerve/arterial injury, complex regional pain syndrome) is recorded and compared between study groups.
