This is a late (about 15 years) follow-up study of a randomized prospective clinical study originally conducted as a collaboration of the Rheumatism Foundation Hospital, Heinola, Finland and Päijät-Häme Central Hospital, Lahti Finland.
For the original study thirty-five patients with symptomatic end-stage inflammatory arthritis of the trapeziometacarpal joint were recruited. All patients signed written informed consent and were randomised to undergo surgery using either tendon interposition or poly-L-D-lactic acid implant interposition arthroplasty of said joint. The study was approved by the Päijät-Häme hospital district ethics committee.
Results of up to two years of follow-up have been published previously (DOI: 10.3109/2000656X.2012.669202).
For the current study all patients included in the final data analysis of the original study are to be contacted for a late follow-up using the same metrics used in the original study (hand pain and hand function rated on a visual analogue scale, hand strenght measurements, hand range of motion measurements, hand dexterity tests and tests simulating hand function in activities of daily living). Additionally outcomes will be assessed using the Patient Rated Wrist/Hand Evaluation and QuickDASH clinical outcome measurement scores.
Collected follow-up data will be statistically analyzed and a summary will be published in a peer-reviewed scientific journal.

|
| Measure | Description | Time Frame |
|---|---|---|
| Hand pain | Pain of the studied / operated hand using a 0-100mm visual analogue scale where 0mm denotes no pain at all and 100mm denotes worst pain imaginable. | Approximately 15 years from enrollment |
| Hand function | Function of the studied / operated hand using a 0-100mm visual analogue scale where 0mm denotes normal hand function and 100mm denotes the hand not functioning at all. | Approximately 15 years from enrollment |
| Hand grip strength | Power grip strength (in kg) measured using a jamar hand dynamometer. Key pinch and tip pinch strength (in kg) mearured using a mechanical pinch gauge. | Approximately 15 years from enrollment |
| QuickDASH score | The Disabilities of the Arm, Shoulder, and Hand (DASH) is a clinical outcome measure questionnaire consisting of thirty questions and has been validated several times. The QuickDASH score includes eleven of those questions and has been validated as well. Both scores are used to evaluate upper limb function and symptoms during the previous week. | The previous week before approximately 15 years from enrollment |
| Hand range of motion | Active range of motion for following joints / parts of the hand: trapeziometacarpal joint radial abduction, thumb metacarpophalangeal joint extension and flexion, thumb interphalangeal joint extension and flexion. | Approximately 15 years from enrollment |
| Box and block dexterity test | The Box and block dexterity consists of a rectangular box with a central dividing wall. The box is set on a table in front of the patient in a lengthwise orientation with the dividing wall at the patients midline. At the beginning of the test all 150 wooden cubes each 2,5cm are placed in the compartment on the side of the hand being tested. The test performed by moving as many 2,5cm wooden cubes one by one by hand from one box to another within 60 seconds as possible. Before the actual test the patient practices performing the test for 15 seconds with each hand, |

At present we have no plan to share IPD as local legislature and the study protocol do not allow us to do so. If other researchers were to ask us to share IPD, we would be happy to apply permission to do so from our institution.

| Poly-L-D-lactic acid implant (RegJoint) interposition arthroplasty | Procedure | Trapeziometacarpal arthroplasty using poly-L-D-lactic acid implant (RegJoint) interposition to fill the space left by resecting affected joint surfaces. |
|
| Approximately 15 years from enrollment |
| Simulated activities of daily living tests | Decanting water from a jug gripping the jug by its handle into a glass / cup. Decanting water from a glass / cup into jug gripping the glass with a palm grip. Cutting medical putty disc with knife and fork simulating cutting food on a plate. Picking up a wooden bead approximately 1cm in diameter using a pinch grip. The test is repeated four times for each hand so that the patient always uses their thumb but the opposing finger is different each time. Grading for all tests: Normal grip / adapted grip / unable to perform. | Approximately 15 years from enrollment |
| Radiological results | Trapeziometacarpal joint (sub)luxation, joint trapeziometacarpal joint space height and bone destruction adjacent to the trapeziometarcpal joint using posterior to anteriot as well as lateral plain radiographs. | Approximately 15 years from enrollment |
| Patient Rated Wrist/Hand Evaluation clinical outcome measure | The Patient-Rated Wrist and Hand Evaluation questionnaire is a region specific, patient reported outcome measure that aims to evaluate pain and disability of the wrist and hand. In one question the patient is asked about their hand / wrist today, while in fifteen questions the patient is asked about their hand / wrist this week. The score has been validated multiple times. | The previous week before approximately 15 years from enrollment |
