A Comparison of Stainless Steel and Bioabsorbable Screw Fixation of Lisfranc Foot Injuries
NCT00985023 · View on ClinicalTrials.gov ↗
Study Summary
The Lisfranc ligaments are a group of ligaments that connect the bones of the middle portion of the foot to each other. The Lisfranc ligaments allow for a normal and stable range of motion and shape to the foot. In certain foot fractures where the Lisfranc ligaments are damaged, the constraint and stability it had given to the middle of the foot is lost. Attempted activity at the foot will result in pain and abnormal motion. If injury to the Lisfranc ligaments is left untreated, the eventual end result is foot arthritis and deformity. The current standard orthopaedic treatment of foot fractures with Lisfranc ligament injuries is surgery. The foot fractures are fixed with metal screws. The Lisfranc ligaments are fixed by compressing the space between the middle bones of the foot with steel screws. These screws allow for ligament healing. As the ligaments heal, the patient should not resume activity with the fixed foot too soon as the screw may break. Upon breakage, the ligament repair may fail and the screw is now difficult to surgically remove. Regardless of breakage, a second surgical procedure is often recommended to remove the steel screw 6 months after foot surgery. This allows for a complete return of normal foot range of motion, but at the cost of a second surgical procedure. The investigators hypothesize that absorbable screw fixation of the Lisfranc ligaments does not yield significant differences in postoperative foot stability, ligament function, and symptoms when compared to steel screw fixation. In addition, absorbable screw fixation of the Lisfranc ligaments offers the advantage that a second surgical procedure to remove the screw is not necessary.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00985023
The ClinicalTrials.gov registry entry for NCT00985023 describes a study currently listed as completed. It is categorized as Phase 4, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 50 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Rothman Institute Orthopaedics, which has 5 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Unstable Lisfranc Fracture-dislocations of the Midfoot appearing as the primary indexed condition, and to 2 interventions — of which Steel screw fixation of Lisfranc fracture-dislocation. is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00985023 reports 2 study locations spanning 1 distinct geographic area — top geographies include Pennsylvania. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
