Patient Reported Function Following Combined First MTP and First TMT Arthrodesis.

October 19, 2023 updated by: Midwest Bunion Center, LLC

What do Patients Report Regarding Their Real-world Function Following Combined First MTP and First TMT Arthrodesis?

The goal of the study is to gather sufficient patient data to assess real world postoperative function after a first metatarsophalangeal (MTP) joint arthrodesis done in conjunction with first tarsometatarsal arthrodesis (TMT) (double fusion). Many studies have demonstrated the success of a first MTP joint arthrodesis in eliminating pain and reducing the intermetatarsal angle. Very little research has been published to assess the outcomes of double arthrodesis. Limited research has specifically assessed patients' everyday function and gait following MTP arthrodesis and no studies are available to assess real world function following double arthrodesis. More data that includes patient reported function during activities of daily living is needed to understand the benefits and draw backs of combined first MTP/TMT joint arthrodesis used to treat and correct first ray deformity.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

  • Retrospective clinical data will be collected on a Clinical Data Collection Form from a chart abstraction at the research site.
  • All radiographs will be anonymized and transferred in a secure process to a Central Radiologist for the study. The data will be collected in excel spreadsheet or on a Radiographic Data Collection Form.
  • Post-operative function and satisfaction will be collected by study personnel via telephone call with the patient
  • De-identified data will be entered into a database for analysis.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Inclusion Criteria:

  1. Patients with surgeon identified indications for double joint arthrodesis
  2. Previous double joint arthrodesis procedure (Lapiplasty® Procedure) between 2017-2021
  3. Procedure completed at least 12 months from the onset of the study
  4. Early weight-bearing protocol (< 3 weeks)
  5. Patients between 18 and 80 years of age, inclusive at the time of the procedure
  6. Clinical and radiographic follow up available at least 6 months post double joint arthrodesis procedure

  • Primary Purpose: Supportive Care
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Other: Patient reported function of daily ADL's post combined first MTP/TMT joint arthrodesis
Patients that meet the inclusion criteria will be contacted for participation in the study. If the patient agrees to participate in the study, informed consent will be obtained. The retrospective study will consist of a chart review and baseline radiographic analysis. The prospective follow-up will consist of the patient completing the Post-Operative Function and Satisfaction Survey via phone call with study staff. Radiographic images will be analyzed by a single central radiologist.
Device: Lapiplasty
The Lapiplasty® System instruments and implants will be retrospectively evaluated in patients previously surgically treated with the Lapiplasty® Procedure for Triplane MTP and TMT joint arthrodesis.
