Clinical Trial Summary

Digital osteoarthritis is the second localization of symptomatic osteoarthritis, after the knee. Its cardinal symptoms are particularly intense pain and functional impairment in the case of the erosive form. There is currently no etiological treatment for osteoarthritis. Symptomatic treatments have a modest efficacy, which justifies the search for new treatments. The surgical options are arthrodesis or prosthesis, invasive techniques potentially sources of complications, and finally proposed infrequently given the prevalence of digital osteoarthritis. DECAD is a prospective phase II trial aimed at evaluating the efficacy of surgical joint denervation in painful digital osteoarthritis.


Description:

Osteoarthritis is the most common joint pathology of the musculoskeletal system. It affects 6 million French people and constitutes a public health problem. Osteoarthritis of the hands or digitalis is the second localization of symptomatic osteoarthritis, after the knee. Its main risk factors are female sex, age, genetic factors, and obesity. Osteoarthritis combines articular cartilage degradation, synovial inflammation, subchondral bone remodeling and osteophyte development. Its cardinal symptoms are pain and functional impairment (at a level sometimes close to inflammatory rheumatism such as rheumatoid arthritis), particularly intense in the case of the erosive form. There is also local joint inflammation associated with pain. Pain in osteoarthritis is a complex phenomenon involving joint tissues other than cartilage, a tissue that is not innervated (subchondral bone, joint capsule, synovial membrane). There is currently no etiological treatment for osteoarthritis. Symptomatic treatments have a modest efficacy, which justifies the search for new treatments. The surgical options are arthrodesis or prosthesis, invasive techniques potentially sources of complications, and finally proposed infrequently given the prevalence of digital osteoarthritis. The only current conservative surgical solution that can be proposed for intractable painful proximal interphalangeal joint (PIPJ) osteoarthritis is denervation. This technique consists of cutting the nerve branches intended for the PIPJ in order to directly interrupt the pain pathways. It reduces pain by 80% after 5 years, without loss of mobility. There are only 4 published series reporting the results of this technique (2-3). These were retrospective case series with a low level of evidence. The patient satisfaction rate reached 90%, with transient paresthesias as the only reported complication. The mechanism of action for the effectiveness of this intervention has never been studied. Our hypothesis is that denervation of the PIP has clinical efficacy in painful digital osteoarthritis refractory to usual treatments, and that it would have a structural effect that can be objectified on MRI. The results of this pilot study will make it possible to construct a prospective randomized study.

Outcome

Type Measure Description Time frame Safety issue
Primary Success of the intervention at 3 months Success of the intervention at 3 months, defined by a reduction in pain of at least 2 points compared to the measurement at inclusion, with the numerical painscale (from 0 to 10) for the operate finger 3 months
Secondary Pain at 6 months Assessement with Numerical pain scale of the operated finger and the operated hand (from 0 to 10) 6 months
Secondary Quality of life at 6 months : Score quick-DASH Calculation of score by quick-DASH questionnary: main functional and quality of life and function score used in hand surgery 6 months
Secondary Quality of life at 6 months : Score AUSCAN Calculation of score by AUSCAN questionnary (Australian/Canadian Osteo Arthritis Hand Index, self-administered questionnaire validated in AD measuring pain, function and stiffness) 6 months
Secondary Grip strength at 6 months Grip strength measured by JAMAR hydraulic dynamometer to assess the impact of pain on function 6 months
Secondary PGI-C Score at 6 months Calculation of score on PGI-C scale (Patient Global Impressions scale-Change, assesses the perception of a change induced by the treatment) to assess patient satisfaction 6 months
