Proximal Row Carpectomy Versus Four Corner Fusion

There are two types of interventions to treat a post-traumatic wrist osteoarthritis: the proximal row carpectomy and the four corner fusion. They are used to reduce pain and to maintain the mobility. In previous studies are shown that the proximal row carpectomy shows a better mobility of the wrist postoperatively, whereas the four corner fusion has lower progression of radiocarpale osteoarthritis.

The purpose of this study is to compare the clinical, radiological and subjective outcomes after the treatment with a proximal row carpectomy or a four corner fusion.

About this study

Two surgical procedures are used to treat a post-traumatic wrist osteoarthritis, especially after scaphoid non-union advanced collapse (SNAC) and scapholunate advanced collapse (SLAC): the proximal row carpectomy and the four corner fusion. Both surgical procedures are rescue operations. They are used to reduce pain and to maintain the mobility, compared to a complete stiffening of the wrist.

In previous studies are shown that the proximal row carpectomy shows a better mobility of the wrist postoperatively and a lower complication rate, whereas the four corner fusion has a lower progression of radiocarpale osteoarthritis and a better grip strength.

The purpose of this study is to compare the clinical, radiological and subjective outcomes after the treatment with a proximal row carpectomy or a four corner fusion.

Treatment and study plan

Proximal Row Carpectomy

Procedure

excision of the scaphoid, lunate and triquetrum

Four corner fusion

Procedure

Primary outcomes

  1. Range of motion of the wrist

    Time frame: participants will be followed up by an expected average of 4.5 years

    measurements of flexion/extension,supination/pronation and radial-/ulnarduction of the wrist

Secondary outcomes

  1. complication rate

    Time frame: participants will be followed up by an expected average of 4.5 years

    Detection of complications of both surgical procedures

Other outcomes

  1. grip strength

    Time frame: participants will be followed up by an expected average of 4.5 years

    measurement of grip strength

  2. Patient-Rated Wirst Evaluation (PRWE)

    Time frame: participants will be followed up by an expected average of 4.5 years

    Comparison of proximal row carpectomy and four corner fusion in respect to PRWE

  4. Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH)

    Time frame: participants will be followed up by an expected average of 4.5 years

    Comparison of proximal row carpectomy and four corner fusion in rsespect to QuickDASH

  5. Detection of radiological parameters

    Time frame: participants will be followed up by an expected average of 4.5 years
