Eligibility Criteria

Inclusion

Inclusion Criteria:

  • Radiological signs of osteoarthritis on posteroanterior and lateral radiograph.

Exclusion

Exclusion Criteria:

  • Previous PIN or AIN neurectomy.

  • Rheumatoid arthritis or other chronic inflammatory arthritis.

  • Symptomatic osteoarthritis in the distal radio-ulnar (DRU),Scapho-trapezio-trapezoid (STT) or thumb carpometacarpal (CMC) joints.

  • Ongoing infection.

  • Inability to co-operate with the follow-up protocol.

  • Systemic or intra-articular glucocorticoids or intraarticular PRP or Hyaluronic acidinjections in the affected joint within 3 months prior to enrollment.

Study Description

Backgroud:

High quality evidence regarding the effectiveness of non-operative and operative treatments in wrist osteoarthritis are lacking.

Aim:

To analyze:

  1. Does partial wrist denervation and self-managed exercise therapy improve patient-reported outcomes, pain, grip strength and range of motion (ROM) in wrist OA?

  2. Is any of the two treatment concepts partial wrist denervation and self-managed exercise therapy more efficient than the other in terms of patient-reported outcomes, pain relief, grip strength and range of motion?

Method:

A multicenter parallel group, two-arm, randomized, controlled, assessor blinded, trial of 140 patients. The study is conducted at the departments of hand surgery at Södersjukhuset Stockholm and Malmö University hospital.

Group1:

Self-managed exercise therapy program containing:

  • Patient education:

  • Exercise therapy program:

The exercise therapy program is designed by Sara Larsson (physiotherapist at the Department of hand surgery in Malmö, Sweden), influenced by previous studies on wrist stability and proprioception. Focus is on functional re-learning and strengthening of the musculoskeletal system with the aim to create a stable wrist that can be used in a pain-free manner in activities of daily living. The program consists of neuromuscular exercises that focus on coordination, wrist stability and strength.

Group 2:

Surgery will be performed under local anesthesia (+ blood-less field or wide-awake local anesthesia no torniquet (WALANT) according to the surgeon's preference) through a single dorsal incision. AIN and PIN neurectomy will be performed as described by Berger (Berger, 1998).

Primary outcome:

Patient Rated Wrist Evaluation (PRWE) score (0-100) (MacDermid et al., 1998) 12 months after intervention.
