Clinical Trial Summary

Study purpose is to compare the outcome after total wrist arthrodesis (TWA) with proximal carpal row (Proximal Row Carpectomy = PRC) as bone graft versus iliac crest cancellous bone graft.

Patients with radiologically and clinically confirmed advanced osteoarthritis are randomized (1:1 computer generated sequence with random block size) to two parallel groups and will undergo either total wrist arthrodesis with PRC or TWA with iliac crest bone grafting.

Baseline data is collected preoperatively and is a follow-up visits at every 6 weeks after the surgery is arranged until the wrist is fused. The primary end-point is 6 months and the primary outcome is fusion rate.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Fusion rate (percent)		6 months
Secondary	Pain (Visual Analogue Scale)	The VAS is derived by health care professional question of pain in scale 0 to 100 mm (0 mm =no pain, 100 mm =worst possible pain)	6 months
Secondary	Patient-Rated Wrist Evaluation (PRWE)	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)	6 months
Secondary	Quick-Disabilities of the Arm, Shoulder and Hand (QuickDASH)	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)	6 months
Secondary	Global improvement	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	6 months
Secondary	Grip strength	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	6 months
Secondary	Operative time	Operative time is measured in minutes for time in the operation theatre and time used for surgery	Perioperative
Secondary	Complications	Incidence of complications (i.e. non-union, fracture, re-operation, infection, hematoma, iatrogenic tendon/nerve/arterial injury, complex regional pain syndrome) is recorded and compared between study groups.	12 months
