Lead Sponsor
Diakonhjemmet Hospital
Brief Summary

A placebo-controlled randomized controlled trial exploring the effect of intraarticular steroids, saline or an occupational therapy intervention in inflammatory carpometacarpal-1 osteoarthritis

Detailed Description

The primary aim of the PICASSO trial is to examine the efficacy and safety of intraarticular corticosteroid injections and a multimodal occupational therapy intervention in patients with CMC-1 OA (Phase 1). By comparing available non-pharmacological and pharmacological treatments head-to-head, our results will be of interest to the range of health professionals who are involved in the management of CMC-1 OA patients. By including patients who are likely to benefit from the intervention (painful and inflammatory CMC-1 OA), appropriate dosage of drug and ultrasound-guided injections, our trial is more guarded against possible false negative results than previous studies. We will also explore predictors for treatment effects. Due to the heterogeneous presentation of OA, it is unlikely that one treatment will fit all, and treatment should be tailored to the patients´ clinical presentation. Second, we will explore the long-term safety of IACS, and whether the occupational therapy intervention can prevent or halt CMC-1 subluxation (Phase 2).

GroupInterventionDescription
Intraarticular corticosteroid injection (IACS)Injection of triamcinolone acetonide into the CMC-1 jointA single ultrasound-guided intraarticular injection of 0.50 ml of 40 mg/ml triamcinolone acetonide at baseline. A smaller dosage can be considered if there is increased resistance during injection. The same injection procedure will be repeated after 12 weeks if there is pain (NRS≥3) and inflammation (grey scale synovitis grade 1-3) present in the CMC-1 joint.
Occupational Therapy interventionMultimodal Occupational therapy for CMC-1 joint OAPatient education, instructions about hand exercises and training in the Happy Hands app. Administration of day and night orthosis. The Happy Hands app involves a 12 week intervention.
Saline injectionPlaceboA single ultrasound-guided intraarticular injection of 0.50 ml of sodium chloride 9 mg/ml at baseline. A smaller dosage can be considered if there is increased resistance during injection. The same injection procedure will be repeated after 12 weeks if there is pain (NRS≥3) and inflammation (grey scale synovitis grade 1-3) present in the CMC-1 joint.
