NCT06546306

Brief Summary

Because severe pain, weakened pinch and grip strength produce functional disabilities, the basal joint of the thumb is the most common site of surgical reconstruction in the upper limb due to OA. The cement-free dual mobility Touch® prosthesis consists of a metacarpal implant (stem), a trapezium implant (cup), and a connection implant (neck). The main objective of this study is to describe the performance and safety of the Touch® prosthesis used with its instruments set in accordance with its intention and CE marking in force. Performance and safety will be assessed over the short and long term in accordance with the life cycle of the Touch® prosthesis.

Sampling MethodProbability Sample
Study Population

Any type of population requiring a surgical procedure covered by the device indications and contraindications.

You may qualify if:

  • Adult patients (age ≥ 18 years),
  • Patients suffering from rhizarthrosis (I - IV based on the Dell classification),
  • Pain \>3 on the VAS scale,
  • Patients to undergo a replacement of the trapeziometacarpal joint with the Touch® dual mobility trapeziometacarpal prosthesis.

You may not qualify if:

  • Pregnant women,
  • Patients with contraindications to surgery in general,
  • Patients suffering from Temporary Regional Pain Syndrome (TRPS),
  • Patients with a severe or chronic, local or systemic infection,
  • Patients with severe muscle, neurological or vascular impairments affecting the trapezium-metacarpal joint,
  • Patients with bone demineralization or destruction that may affect the proper fixation of the implant,
  • Patients whose bone dimensions are incompatible with the implant dimensions,
  • The combination of the Touch® prosthesis with other components of another origin is not authorized,
  • Patients with allergies to the components of the product or with known allergies (chromium, cobalt, nickel),
  • Patients with an intellectual disability who cannot, therefore, follow the instructions of their surgeon,
  • Patient with scaphoid-trapezium-trapezoid (STT) arthritis,
  • Patient requiring revision of a trapeziometacarpal prosthesis,
  • Patient who has undergone a TMC joint infiltration within 3 months of the expected date of replacement of the joint with a Touch® prosthesis.
