Clinical Evaluation of the Articulinx InterCarpoMetacarpal Cushion (ICMC) for Osteoarthritis of the First Metacarpal Joint
Study Overview
Status
Conditions
Detailed Description
The Articulinx ICMC is intended to be implanted into the basilar, or first carpometacarpal (CMC) joint, as an interpositional spacer between the first metacarpal and trapezium bones. The device is intended to be used in the treatment of thumb disabilities resulting from osteoarthritis of the CMC-1 joint.
The primary objective is to document the performance of the Articulinx ICMC by evaluating pain relief in the CMC joint following device implantation. CMC-1 joint function will be assessed by measurement of lateral key and tripod pinch strength, grip strength, and range of motion. Patient reported physical functioning and symptoms will be measured by DASH scores. Trapezial height will be measured on standard PA xrays of the CMC joint. Incidence of unanticipated device and procedure related adverse events will be documented intraoperatively through one year follow-up.
Primary and secondary outcomes will be evaluated through one year and subjects will continue to be followed for two years for evaluation of longer term performance.

Description
Inclusion Criteria:
- Patient is diagnosed by the investigator to be medically acceptable for a surgical procedure
- Patient is aged 40 to 75 inclusive
- Patient has symptomatic osteoarthritis of the carpometacarpal (CMC-1) joint as demonstrated by a minimum DASH score of 40 at baseline
- Patient has pain in the target CMC joint as demonstrated by an average VAS pain score greater than or equal to 40 at baseline on a 100mm VAS
- Patient has radiographic evidence of Stage II OA with no free-floating bodies in the CMC-1 joint
- Patient has subluxation of less than one-third of the target CMC joint
- Patient agrees to return to the clinic for follow-up visits at the required times per protocol and follow the requirements of this protocol
- Patient is able and willing to provide voluntary consent to participate
Exclusion Criteria:
- Patient has non-symptomatic osteoarthritis of the first CMC joint
- Patient has small bone or calcific fragments (spurs, osteophytes) in the target CMC joint greater than two millimeters (>2mm) in diameter
- Patient has free floating bodies of any size within the target CMC joint
- Patient has radiographic/imaging evidence of significant osteoarthritic changes within the first metacarpal, or scaphotrapezotrapezoidal (STT) joint of the target wrist consistent with Stage III/IV OA, according to Eaton-Glickel
- Patient has concomitant musculoskeletal pathology of the target hand, such as carpal tunnel syndrome, palmar tenosynovitis, schaphoulnate ligament instability/degeneration, ulnocarpal impaction syndrome, or trigger finger
- Patient has concomitant rheumatic disease (e.g., inflammatory rheumatoid arthritis, cutaneous psoriasis, polyarticular chondrocalcinosis, gout, fibromyalgia) or exhibits signs of metabolic disorders affecting the bone or joint (e.g., osteoporosis,osteomalacia, hyper- or hypo-parathyroidism,Paget's disease)
- Patient has an active infection, sepsis or osteomyelitis
- Patient has skin disease or eruption at the CMC target site
- Patient had previous surgery on the target CMC joint or; prior surgery within the previous 12 months on the wrist of the target hand that could alter the biomechanics of the wrist or CMC-1 joint or; prior surgery on the wrist of the target hand more than 12 months previously fro which there are existing sequelae
- Patient had significant injury to the target CMC joint within the 6 months prior to study enrollment or a significant permanent injury at any time prior to study enrollment
- Patient has a significant comorbid medical condition that could exacerbate pain symptoms or adversely affect physical functioning or healing of the thumb CMC joint (e.g. de Quervains disease, Ehler-Danlos Syndrome, Complex Regional Pain Syndrome)
- Patient has had corticosteroid injections in the target CMC joint within 6 months prior to study enrollment
- Patient takes concomitant immunosuppressive therapy (e.g., oral/injectable glucocorticoids, alkylating agents, antimetabolites, antibodies, drugs acting on immunophilins [Ciclosporin, Sirolimus], interferons, opioids) that could adversely affect healing
- Patient has uncontrolled diabetes mellitus
- Patient takes anticoagulation and or antiplatelet therapy that cannot be stopped prior to surgery
- Patient is planning a pregnancy, or patient is pregnant and/or lactating
- Patient is participating in any other clinical investigation that could impact the outcome of this study
- Patient has a known history of drug or alcohol abuse in the previous 12 months
- Patient has a history of, or is currently engaged in, litigation for musculoskeletal injuries or disorders or medical malpractice
- Patient has other life circumstances that the Investigator feels would interfere with study participation such as planned relocation, difficulty complying with schedule of study follow-up visits, is generally uncooperative
