Trial summary

The scaphotrapeziotrapezoid (STT) joint is a dome shaped joint in the radial wrist that is important in transfer of load from the thumb and radial hand to the scaphoid and the radioscaphoid and scaphocapitate joints. Read more about this study

About this study

The scaphotrapeziotrapezoid (STT) joint is a dome shaped joint in the radial wrist that is important in transfer of load from the thumb and radial hand to the scaphoid and the radioscaphoid and scaphocapitate joints. Arthritis in this joint is the second most common degenerative arthritis in the wrist, reported in 15% of wrist radiographs. The true incidence of arthritis in the STT joint however is unknown though we assume that most cases of arthritis are not clinically significant. Furthermore, the clinical and biomechanical significance of arthritis in this joint is unclear. The investigators' clinical impression is that the incidence of STT joint arthritis is inversely related to that of radiocarpal joint arthritis. In an ongoing study, we are examining the relationship between STT joint arthritis and radiocarpal joint arthritis on radiographs.

We suggest that STT joint arthritis alters the biomechanics of the wrist by limiting movement of the scaphoid within the STT joint thereby protecting the wrist from radiocarpal arthritis by limiting instability of the scaphoid.

The specific aims of this pilot study are to evaluate the movement of the arthritic scaphoid within the STT joint using a computer-generated model based on CT scan of the wrist and to compare this model with the already established model of the normal STT joint.

The investigators' hypothesis is that there is significantly less motion in the arthritic STT joint.

Read the detailed description

Because it is poorly understood, the treatment of wrist arthritis remains limited to suboptimal salvage operations and wrist fusions. These are surgeries, which greatly limit function. This study is designed to evaluate arthritis of the STT joint and its affect on arthritis in other parts of the wrist. This may improve the understanding of wrist mechanics enabling us to develop better treatment of wrist arthritis. STT joint arthrodesis is an accepted surgery whose indications may be influenced by information obtained in this study.

Five patients being treated by the PI that have a diagnosis or a finding of STT joint arthritis stage 3 on X-ray will be included in the study. The radiographs are standard of care for various hand and wrist conditions and patients will be sent for radiographs only as part of their care. The patients will be eligible for the study following informed consent. The CT scan will be performed at 5-7 wrist positions: neutral, maximum extension, flexion, radial deviation, ulnar deviation (plus radial extension and ulnar flexion for 7 positions). Slice thickness will be less than 1 mm. The slices will be located between distal radioulnar joint (DRUJ) and the 2nd carpometacarpal (CMC) joint. The CT scans will then be sent for evaluation by the computer based kinematic program. No identifiable information will be collected or recorded. The program will develop a kinematic model of the STT joint in the presence of arthritis.

The model (kinematic data) will be compared to an existent "normal" model, based on 7 CT scans of normal STT joints. This data is already in existence and therefore no normal wrists are accrued.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. motion in the STT joint

    A kinematic model based on data from the wrist CT acquired in the different wrist positions.(kinematic data) will be compared to an existent "normal" model, based on 7 CT scans of normal STT joints.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Wrist Osteoarthritis, run by Clalit Health Services at 1 site in Israel.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Jan 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

motion in the STT joint (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jan 2018.
